                               EXPLANATION

    The Code of Federal Regulations is a codification of the general and 
permanent rules published in the Federal Register by the Executive 
departments and agencies of the Federal Government. The Code is divided 
into 50 titles which represent broad areas subject to Federal 
regulation. Each title is divided into chapters which usually bear the 
name of the issuing agency. Each chapter is further subdivided into 
parts covering specific regulatory areas.
    Each volume of the Code is revised at least once each calendar year 
and issued on a quarterly basis approximately as follows:

Title 1 through Title 16.................................as of January 1
Title 17 through Title 27..................................as of April 1
Title 28 through Title 41...................................as of July 1
Title 42 through Title 50................................as of October 1

    The appropriate revision date is printed on the cover of each 
volume.

LEGAL STATUS

    The contents of the Federal Register are required to be judicially 
noticed (44 U.S.C. 1507). The Code of Federal Regulations is prima facie 
evidence of the text of the original documents (44 U.S.C. 1510).

HOW TO USE THE CODE OF FEDERAL REGULATIONS

    The Code of Federal Regulations is kept up to date by the individual 
issues of the Federal Register. These two publications must be used 
together to determine the latest version of any given rule.
    To determine whether a Code volume has been amended since its 
revision date (in this case, April 1, 2015), consult the ``List of CFR 
Sections Affected (LSA),'' which is issued monthly, and the ``Cumulative 
List of Parts Affected,'' which appears in the Reader Aids section of 
the daily Federal Register. These two lists will identify the Federal 
Register page number of the latest amendment of any given rule.

EFFECTIVE AND EXPIRATION DATES

    Each volume of the Code contains amendments published in the Federal 
Register since the last revision of that volume of the Code. Source 
citations for the regulations are referred to by volume number and page 
number of the Federal Register and date of publication. Publication 
dates and effective dates are usually not the same and care must be 
exercised by the user in determining the actual effective date. In 
instances where the effective date is beyond the cut-off date for the 
Code a note has been inserted to reflect the future effective date. In 
those instances where a regulation published in the Federal Register 
states a date certain for expiration, an appropriate note will be 
inserted following the text.

OMB CONTROL NUMBERS

    The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires 
Federal agencies to display an OMB control number with their information 
collection request.

[[Page vi]]

Many agencies have begun publishing numerous OMB control numbers as 
amendments to existing regulations in the CFR. These OMB numbers are 
placed as close as possible to the applicable recordkeeping or reporting 
requirements.

PAST PROVISIONS OF THE CODE

    Provisions of the Code that are no longer in force and effect as of 
the revision date stated on the cover of each volume are not carried. 
Code users may find the text of provisions in effect on any given date 
in the past by using the appropriate List of CFR Sections Affected 
(LSA). For the convenience of the reader, a ``List of CFR Sections 
Affected'' is published at the end of each CFR volume. For changes to 
the Code prior to the LSA listings at the end of the volume, consult 
previous annual editions of the LSA. For changes to the Code prior to 
2001, consult the List of CFR Sections Affected compilations, published 
for 1949-1963, 1964-1972, 1973-1985, and 1986-2000.

``[RESERVED]'' TERMINOLOGY

    The term ``[Reserved]'' is used as a place holder within the Code of 
Federal Regulations. An agency may add regulatory information at a 
``[Reserved]'' location at any time. Occasionally ``[Reserved]'' is used 
editorially to indicate that a portion of the CFR was left vacant and 
not accidentally dropped due to a printing or computer error.

INCORPORATION BY REFERENCE

    What is incorporation by reference? Incorporation by reference was 
established by statute and allows Federal agencies to meet the 
requirement to publish regulations in the Federal Register by referring 
to materials already published elsewhere. For an incorporation to be 
valid, the Director of the Federal Register must approve it. The legal 
effect of incorporation by reference is that the material is treated as 
if it were published in full in the Federal Register (5 U.S.C. 552(a)). 
This material, like any other properly issued regulation, has the force 
of law.
    What is a proper incorporation by reference? The Director of the 
Federal Register will approve an incorporation by reference only when 
the requirements of 1 CFR part 51 are met. Some of the elements on which 
approval is based are:
    (a) The incorporation will substantially reduce the volume of 
material published in the Federal Register.
    (b) The matter incorporated is in fact available to the extent 
necessary to afford fairness and uniformity in the administrative 
process.
    (c) The incorporating document is drafted and submitted for 
publication in accordance with 1 CFR part 51.
    What if the material incorporated by reference cannot be found? If 
you have any problem locating or obtaining a copy of material listed as 
an approved incorporation by reference, please contact the agency that 
issued the regulation containing that incorporation. If, after 
contacting the agency, you find the material is not available, please 
notify the Director of the Federal Register, National Archives and 
Records Administration, 8601 Adelphi Road, College Park, MD 20740-6001, 
or call 202-741-6010.

CFR INDEXES AND TABULAR GUIDES

    A subject index to the Code of Federal Regulations is contained in a 
separate volume, revised annually as of January 1, entitled CFR Index 
and Finding Aids. This volume contains the Parallel Table of Authorities 
and Rules. A list of CFR titles, chapters, subchapters, and parts and an 
alphabetical list of agencies publishing in the CFR are also included in 
this volume.

[[Page vii]]

    An index to the text of ``Title 3--The President'' is carried within 
that volume.
    The Federal Register Index is issued monthly in cumulative form. 
This index is based on a consolidation of the ``Contents'' entries in 
the daily Federal Register.
    A List of CFR Sections Affected (LSA) is published monthly, keyed to 
the revision dates of the 50 CFR titles.

REPUBLICATION OF MATERIAL

    There are no restrictions on the republication of material appearing 
in the Code of Federal Regulations.

    Source: 49 FR 11165, Mar. 26, 1984, unless otherwise noted.



Sec. 2002.1  Scope of the part and applicability of other HUD regulations.

    (a) General. This part contains the regulations of the Office of 
Inspector General which implement the Freedom of Information Act (5 
U.S.C. 552). It informs the public how to request records and 
information from the Office of Inspector General and explains the 
procedure to use if a request is denied. Requests for documents made by 
subpoena or other order are governed by procedures contained in part 
2004 of this chapter. In addition to the regulations in this part, the 
following provisions of part 15 of this title covering the production or 
disclosure of material or information apply (except as limited in 
paragraph (b) of this section) to the production or disclosure of 
material in the possession of the Office of Inspector General:
    Sec. 15.2--What definitions apply to this part?
    Sec. 15.3--What exemptions are authorized by 5 U.S.C. 552?;
    Sec. 15.108--What are HUD's policies concerning designating

    Sec. 15.110--What fees will HUD charge?
    (b) Limited applicability of section 15.110. For purposes of this 
part, paragraphs (d) through (k) of Sec. 15.110 are not applicable.
    (c) Use of the term ``HUD''. For purposes of this part, and when the 
words ``HUD'' or ``Department'' are used in this part or Sec. Sec. 
15.2(b), 15.3, 15.108 and 15.110 of this title, the term means the 
Office of the Inspector General.
    (d) Request for declassification and release of classified material. 
Section 15.107 of this title contains provisions for requesting 
declassification and release of declassified material.

[67 FR 47216, July 17, 2002]



Sec. 2002.3  OIG's overall policy concerning discloseable records and 
requests for OIG records.

    (a) The Office of Inspector General will fully and responsibly 
disclose its identifiable records and information consistent with 
competing public interests, such as national security, personal privacy, 
grand jury and investigative secrecy, complainant confidentiality, 
agency deliberative process, as are recognized by FOIA and other federal 
statutes.
    (b) A request for Office of Inspector General records may be made in 
person during normal business hours at any office where Office of 
Inspector General employees are permanently stationed. Although oral 
requests may be honored, a requester may be asked to submit the request 
in writing. A written request shall be addressed to: The Office of 
Inspector General, Department of Housing and Urban Development, 451 
Seventh Street, SW, Room 8260, Washington, DC 20410.
    (c) Each request must reasonably describe the desired record 
including the name, subject matter, and number or date, where possible, 
so that the record

[[Page 10]]

may be identified and located. The request should also include the name, 
address and telephone number of the requester, and the format in which 
the requester would like the desired record to be reproduced. In order 
to enable the Office of Inspector General to comply with the time 
limitations set forth in Sec. 2002.17, both the envelope containing a 
written request and the letter itself should clearly indicate that the 
subject is a Freedom of Information Act request.
    (d) The request must be accompanied by the fee or an offer to pay 
the fee as determined in Sec. 15.110.
    (e) Copies of available records will be made as promptly as 
possible. Copying service will be limited to not more than 10 copies of 
any single page. Records that are published or available for sale need 
not be reproduced.
    (f) To the extent that records are readily reproducible, the Office 
of Inspector General will send records in the form requested, including 
electronic format.

[67 FR 47217, July 17, 2002]



Sec. 2002.5  Records produced upon request when reasonably described.

    (a) When a request is made which reasonably describes a record of 
the Office of Inspector General (see Sec. 2002.3) which has been stored 
in the National Archives or other record center of the General Services 
Administration, the record will be requested by the Office of Inspector 
General if it otherwise would be available under this part.
    (b) Every effort will be made to make a record in use by the staff 
of the Office of Inspector General available when requested, and such 
availability will be deferred only to the extent necessary to avoid 
serious interference with the business of the Office of Inspector 
General.



Sec. 2002.7  OIG processing of requests.

    (a) Multitracking. (1) The Office of Inspector General places each 
request in one of two tracks. The Office of Inspector General places 
requests in its simple or complex track based on the amount of work and 
time involved in processing the request. Factors the Office of Inspector 
General will consider in assigning a request in the simple or complex 
track will include whether the request involves the processing of 
voluminous documents and/or whether the request involves responsive 
documents from more than one organizational unit. Within each track, the 
Office of Inspector General processes requests in the order in which 
they are received.
    (2) For requests that have been sent to the wrong office, the Office 
of Inspector General will assign the request within each track using the 
earlier of either:
    (i) The date on which the request was referred to the appropriate 
office; or,
    (ii) The end of the ten (10) working day period in which the request 
should have been referred to the appropriate office.
    (b) Expedited processing. The Office of Inspector General may take 
your request or appeal out of normal order if the Office of Inspector 
General determines that you have a compelling need for the records or in 
other cases as determined by the Office of Inspector General. If the 
Office of Inspector General grants your request for expedited 
processing, the Office of Inspector General will give your request 
priority and will process it as soon as practicable. The Office of 
Inspector General will consider a compelling need to exist if:
    (1) Your failure to obtain the requested records on an expedited 
basis could reasonably be expected to pose an imminent threat to the 
life or physical safety of an individual or a threatened loss of 
substantial due process rights; or,
    (2) You are primarily engaged in disseminating information and there 
is an urgency to inform the public concerning actual or alleged Federal 
Government activity.

[67 FR 47217, July 17, 2002]



Sec. 2002.9  Where to review records.

    (a) You may inspect and copy hardcopy records that section 552(a)(2) 
of FOIA requires the Office of Inspector General make available to the

Sec. 2002.11  Review of records, aggregating requests and waiving or 
reducing fees.

    (a) Review of records. Only requesters who are seeking documents for 
commercial use may be charged for the time HUD spends reviewing records 
to determine whether they are exempt from mandatory disclosure. Charges 
may be assessed only for the initial review (i.e., the review undertaken 
the first time HUD analyzes the applicability of a specific exemption to 
a particular record or portion of a record). HUD will not charge for 
review at the administrative appeal level of an exemption already 
applied. However, records or portions of records withheld in full under 
an exemption which is subsequently determined not to apply may be 
reviewed again to determine the applicability of other exemptions not 
previously considered. The costs for such a subsequent review would be 
properly assessable. Review time will be assessed at the same rates 
established for search time in Sec. 15.110 of this title.
    (b) Aggregating requests. A requester may not file multiple requests 
at the same time, each seeking portions of a document or documents, 
solely in order to avoid payment of fees. When HUD reasonably believes 
that a requester or a group of requesters acting in concert, is 
attempting to break a request down into a series of requests for the 
purpose of evading the assessment of fees, HUD may aggregate any such 
requests and charge accordingly.
    (c) Waiving or reducing fees. HUD will furnish documents without 
charge or at reduced charge if disclosure of the information is in the 
public interest because it is likely to contribute significantly to 
public understanding of the operations or activities of the government 
and is not primarily in the commercial interest of the requester. The 
official authorized to grant access to records may waive or reduce the 
applicable fee where requested. The determination not to waive or reduce 
the fee will be subject to administrative review as provided in Sec. 
2002.25 after the decision on the request for access has been made. Six 
factors shall be used in determining whether the requirements for a fee 
waiver or reduction are met. These factors are as follows:
    (1) The subject of the request: Whether the subject of the requested 
records concerns ``the operations or activities of the government'';
    (2) The informative value of the information to be disclosed: 
Whether the disclosure is ``likely to contribute'' to an understanding 
of government operations or activities;
    (3) The contribution to an understanding of the subject by the 
general public likely to result from disclosure: Whether disclosure of 
the requested information will contribute to ``public understanding'';
    (4) The significance of the contribution to public understanding: 
Whether the disclosure is likely to contribute ``significantly'' to 
public understanding of government operations or activities;
    (5) The existence and magnitude of a commercial interest: Whether 
the requester has a commercial interest that would be furthered by the 
requested disclosure; and, if so
    (6) The primary interest in disclosure: Whether the magnitude of the 
identified commercial interest of the requester is sufficiently large, 
in comparison with the public interest in disclosure, that disclosure is 
``primarily in the commercial interest of the requester.''

[53 FR 37551, Sept. 27, 1988, as amended at 67 FR 47217, July 17, 2002]



Sec. 2002.13  Charges for interest and for unsuccessful searches; 
utilization of Debt Collection Act.

    (a) Charging interest. HUD will begin assessing interest charges on 
an unpaid bill starting on the 31st day following the day on which the 
billing was sent. A fee received by HUD, even if not processed, will 
suffice to stay the accrual of interest. Interest will be at the rate 
prescribed in section 3717 of title 31 U.S.C. and will accrue from the 
date of the billing.

[[Page 12]]

    (b) Charge for unsuccessful search. Ordinarily no charge for search 
time will be assessed when the records requested are not found or when 
the records located are withheld as exempt. However, if the requester 
has been notified of the estimated cost of the search time and has been 
advised specifically that the requested records may not exist or may be 
withheld as exempt, fees shall be charged.
    (c) Use of Debt Collection Act of 1982. When a requester has failed 
to pay a fee charged in a timely fashion (i.e., within 30 days of the 
date of the billing), HUD may, under the authority of the Debt 
Collection Act and part 17, subpart C of this title, use consumer 
reporting agencies and collection agencies, where appropriate, to 
recover the indebtedness owed the Department.

[53 FR 37552, Sept. 27, 1988]



Sec. 2002.15  Advance payments.

    (a) HUD may not require a requester to make an advance payment, 
i.e., payment before work is commenced or continued on a request, 
unless:
    (1) HUD estimates or determines that allowable charges that a 
requester may be required to pay are likely to exceed $250. Then, HUD 
will notify the requester of the likely cost and obtain satisfactory 
assurance of full payment where the requester has a history of prompt 
payment of FOIA fees, or require an advance payment of an amount up to 
the full estimated charges in the case of requesters with no history of 
payment; or
    (2) Where a requester has previously failed to pay a fee charged in 
a timely fashion (i.e., within 30 days of the date of the billing), HUD 
may require the requester to pay the full amount owed plus any 
applicable interest as provided by Sec. 2002.13(a) or demonstrate that 
he has, in fact, paid the fees, and to make an advance payment of the 
full amount of the estimated fee before HUD begins to process a new 
request or a pending request from that requester.
    (b) When HUD acts under paragraph (a)(1) or (a)(2) of this section, 
the administrative time limits prescribed in subsection (a)(6) of the 
FOIA (i.e., 20 working days from receipt of initial requests and 20 
working days from receipt of appeals from initial denial, plus 
permissible extensions of these time limits) will begin only after HUD 
has received fee payments described in paragraph (a) of this section.
    (c) Where it is anticipated that either the duplication fee 
individually, the search fee individually, or a combination of the two 
exceeds $25.00 over and above the free search time and duplication 
costs, where applicable, and the requesting party has not indicated in 
advance a willingness to pay so high a fee, the requesting party shall 
be promptly informed of the amount of the anticipated fee or such 
portion thereof as can readily be estimated. The notification shall 
offer the requesting party the opportunity to confer with agency 
representatives for the purpose of reformulating the request so as to 
meet that party's needs at a reduced cost.

[53 FR 37552, Sept. 27, 1988, as amended at 67 FR 47217, July 17, 2002]



Sec. 2002.17  Time limitations.

    (a) Upon receipt of a request for records, the appropriate Assistant 
Inspector General or an appointed designee will determine within twenty 
(20) working days whether to grant the request. The Assistant Inspector 
General or designee will notify the requestor immediately in writing of 
the determination and the right of the person to request a review by the 
Inspector General of an adverse determination.
    (b) The time of receipt for processing a request for records 
purposes is the time it is received by the appropriate office for 
review. If a request is misdirected by the requester, the Office of 
Inspector General or Department official who receives the request will 
promptly refer it to the appropriate office and will advise the 
requester about the delayed time of receipt.
    (c) A determination with respect to a request for review by the 
Inspector General of HUD under Sec. 2002.25 will be made within 20 
working days after receipt and will be communicated immediately to the 
person requesting review.
    (d) If the Office of Inspector General grants the request for 
records, the records will be made available promptly to the requester.

[[Page 13]]

    (e) In unusual circumstances as specified in this paragraph, and 
subject to the concurrence of any Assistant Inspector General or 
appointed designee, the time limits prescribed in either paragraph (a) 
or (c) of this section may be extended. Any extension will be in writing 
to the requester and will include reasons for the extension and the date 
on which the disposition of the request will be sent. No extension will 
be for more than ten working days. As used in this paragraph, unusual 
circumstances means (but only to the extent necessary to the proper 
processing of the particular request) that there is a need:
    (1) To search for and collect the requested records from field 
facilities or other establishments that are separate from the office 
processing the request; or
    (2) To search for, collect, and appropriately examine a voluminous 
amount of separate and distinct records which are demanded in a single 
request; or
    (3) For consultation, which shall be conducted with all practicable 
speed, with another agency having a substantial interest in the 
determination of the request or among two or more offices of the Office 
of Inspector General having a substantial interest in the subject matter 
of the request.

    Any Assistant Inspector General or an appointed designee is 
authorized to release any record (or copy) pertaining to activities for

inappropriate under this part. No authorized person may release records 
for which another officer has primary responsibility without the consent 
of the officer or his or her designee.

executive order to be kept secret in the interest of national defense or 
foreign policy; and
    (ii) Are in fact properly classified under the cited executive 
order;
    (2) Related solely to the internal personnel rules and practices of 
HUD;
    (3) Specifically exempted from disclosure by statute (other than 
section 552b of title 5), provided that the statute either:
    (i) Requires that the matters be withheld from the public in a 
manner that leaves no discretion on the issue; or
    (ii) Establishes particular criteria for withholding or refers to 
particular types of matters to be withheld;
    (4) Trade secrets and commercial or financial information that are 
obtained from a person and are privileged or confidential;
    (5) Inter-agency or intra-agency memoranda or letters that would not 
be available by law to a party other than an agency in litigation with 
HUD;
    (6) Personnel and medical files and similar files the disclosure of 
which would constitute a clearly unwarranted invasion of personal 
privacy;
    (7) Records or information compiled for law enforcement purposes, 
but only to the extent that the production of such law enforcement 
records or information:
    (i) Could reasonably be expected to interfere with enforcement 
proceedings;

[[Page 14]]

    (ii) Would deprive a person of a right to a fair trial or an 
impartial adjudication;
    (iii) Could reasonably be expected to constitute an unwarranted 
invasion of personal privacy;
    (iv) Could reasonably be expected to disclose the identity of a 
confidential source, including a state, local, or foreign agency or

source;
    (v) Would disclose techniques and procedures for law enforcement 
investigations or prosecutions, or would disclose guidelines for law 
enforcement investigations or prosecutions if the disclosure could 
reasonably be expected to risk circumvention of the law; or
    (vi) Could reasonably be expected to endanger the life or physical 
safety of any individual;
    (8) Contained in or related to examination, operating, or condition 
reports prepared by, on behalf of, or for the use of an agency 
responsible for the regulation or supervision of financial institutions; 
or
    (9) Geological and geophysical information and data, including maps, 
concerning wells.
    (c) With regard to a request for commercial or financial 
information, predisclosure notification to business submitters is

the business submitter an opportunity to object to disclosure of the 
requested information.
    (d) Any reasonably segregable portion of a record shall be provided 
to any person requesting the record, after deletion of the portions that 
are exempt under this section.

Sec. 2002.25  Administrative review.

    (a) Review is available only from a written denial of a request for 
a record issued under Sec. 2002.21 and only if a written request for 
review is filed within 30 days after issuance of the written denial.
    (b) A review may be initiated by mailing a request for review to the 
Inspector General of HUD, Department of Housing and Urban Development, 
451 Seventh Street, SW., Room 8256, Washington, DC 20410. Each request 
for review must contain the following:
    (1) A copy of the request, if in writing;
    (2) A copy of the written denial issued under Sec. 2002.21; and
    (3) A statement of the circumstances, reasons, or arguments advanced 
in support of disclosure of the original request for the record.

In order to enable the Inspector General of HUD to comply with the time 
limitations set forth in Sec. 2002.17, both the envelope containing the 
request for review and the letter itself should clearly indicate that 
the subject is a Freedom of Information Act request for review.
    (c) Review will be made promptly by the Inspector General of HUD on 
the basis of the written record described in paragraph (b) of this 
section. Before a denial, the Inspector General will obtain the 
concurrence of legal counsel for the Office of Inspector General.
    (d) The time of receipt for processing of a request for review 
purposes is the time it is received by the Inspector General of HUD. If 
a request is misdirected by the requester and is received by one other 
than the Inspector General, the Office of Inspector General or 
Department official who receives the request will forward it promptly to 
the Inspector General and will advise the requester about the delayed 
time of receipt.
    (e) The decision after review will be in writing, will constitute 
final agency

action on the request, and, if the denial of the request for records is 
in full or in part upheld, the Inspector General will notify the person 
making the request of his or her right to seek judicial review under 5 
U.S.C. 552(a)(4).

that are contained in systems of records maintained by the OIG and that 
are retrieved by an individual's name or personal identifier.
    (b) Applicability of part 16. In addition to these regulations, the 
provisions of 24 CFR part 16 apply to the OIG, except that appendix A to 
part 16 is not applicable. The provisions of this part shall govern in

Sec. 2003.3  Requests for records.

    (a) A request from an individual for an OIG record about that 
individual which is not contained in an OIG system of records will be 
considered to be a Freedom of Information Act (FOIA) request and will be 
processed under 24 CFR part 2002.
    (b) A request from an individual for an OIG record about that 
individual which is contained in an OIG system of records will be 
processed under both the Privacy Act and the FOIA in order to ensure 
maximum access under both statutes. This practice will be undertaken 
regardless of how an individual characterizes the request.
    (1) The procedures for inquiries and requirements for access to 
records under the Privacy Act are more specifically set forth in 24 CFR 
part 16, except that appendix A to part 16 does not apply to the OIG.
    (2) An individual will not be required to state a reason or 
otherwise justify his or her request for access to a record.



Sec. 2003.4  Officials to receive requests and inquiries.

    Officials to receive requests and inquiries for access to, or

Officers described in Sec. 2003.2 of this part. Written requests may be 
addressed to the appropriate Privacy Act Officer at: Office of Inspector 
General, Department of Housing and Urban Development, Washington, DC 
20410.

[[Page 16]]



Sec. 2003.5  Initial denial of access to records.

    (a) Access by an individual to a record about that individual which 
is contained in an OIG system of records will be denied only upon a 
determination by the Privacy Act Officer that:
    (1) The record was compiled in reasonable anticipation of a civil 
action or proceeding; or the record is subject to a Privacy Act 
exemption under Sec. 2003.8 or Sec. 2003.9 of this part; and
    (2) The record is also subject to a FOIA exemption under Sec. 
2002.21(b) of this chapter.
    (b) If a request is partially denied, any portions of the responsive 
record that can be reasonably segregated will be provided to the 
individual after deletion of those portions determined to be exempt.
    (c) The provisions of 24 CFR 16.6(b) and 16.7, concerning 
notification of an initial denial of access and administrative review of 
the initial denial, apply to the OIG, except that:
    (1) The final determination of the Inspector General, as Privacy 
Appeals Officer for the OIG, will be in writing and will constitute 
final action of the Department on a request for access to a record in an 
OIG system of records; and
    (2) If the denial of the request is in whole or in part upheld, the 
final determination of the Inspector General will include notice of the 
right to judicial review.



Sec. 2003.6  Disclosure of a record to a person other than the individual
to whom it pertains.

    (a) The OIG may disclose an individual's record to a person other 
than the individual to whom the record pertains in the following 
instances:
    (1) Upon written request by the individual, including authorization 
under 24 CFR 16.5(e);
    (2) With the prior written consent of the individual;
    (3) To a parent or legal guardian of the individual under 5 U.S.C. 
552a(h); or
    (4) When permitted by the provisions of 5 U.S.C. 552a(b) (1) through 
(12).
    (b) [Reserved]



Sec. 2003.7  Authority to make law enforcement-related requests for records
maintained by other agencies.

    (a) The Inspector General is authorized by written delegation from 
the Secretary of HUD and under the Inspector General Act to make written 
requests under 5 U.S.C. 552a(b)(7) for transfer of records maintained by 
other agencies which are necessary to carry out an authorized law 
enforcement activity under the Inspector General Act.
    (b) The Inspector General delegates the authority under paragraph 
(a) of this section to the following OIG officials:
    (1) Deputy Inspector General;
    (2) Assistant Inspector General for Audit;
    (3) Assistant Inspector General for Investigation; and
    (4) Assistant Inspector General for Management and Policy.
    (c) The officials listed in paragraph (b) of this section may not 
redelegate the authority described in paragraph (a) of this section.



Sec. 2003.8  General exemptions.

    (a) The systems of records entitled ``Investigative Files of the 
Office of Inspector General,'' ``Hotline Complaint Files of the Office 
of Inspector General,'' ``Name Indices System of the Office of Inspector 
General,'' and ``AutoInvestigation of the Office of Inspector General'' 
consist, in part, of information compiled by the OIG for the purpose of 
criminal law enforcement investigations. Therefore, to the extent that 
information in these systems falls within the scope of exemption (j)(2) 
of the Privacy Act, 5 U.S.C. 552a(j)(2), these systems of records are 
exempt from the requirements of the following subsections of the Privacy 
Act, for the reasons stated in paragraphs (a)(1) through (6) of this 
section.
    (1) From subsection (c)(3), because release of an accounting of 
disclosures to an individual who is the subject of an investigation 
could reveal the nature and scope of the investigation and could result 
in the altering or destruction of evidence, improper influencing of 
witnesses, and other evasive actions that could impede or compromise the 
investigation.

[[Page 17]]

    (2) From subsection (d)(1), because release of investigative records 
to an individual who is the subject of an investigation could interfere 
with pending or prospective law enforcement proceedings, constitute an 
unwarranted invasion of the personal privacy of third parties, reveal 
the identity of confidential sources, or reveal sensitive investigative 
techniques and procedures.
    (3) From subsection (d)(2), because amendment or correction of 
investigative records could interfere with pending or prospective law 
enforcement proceedings, or could impose an impossible administrative 
and investigative burden by requiring the OIG to continuously retrograde 
its investigations attempting to resolve questions of accuracy, 
relevance, timeliness and completeness.
    (4) From subsection (e)(1), because it is often impossible to 
determine relevance or necessity of information in the early stages of 
an investigation. The value of such information is a question of 
judgment and timing; what appears relevant and necessary when collected 
may ultimately be evaluated and viewed as irrelevant and unnecessary to 
an investigation. In addition, the OIG may obtain information concerning 
the violation of laws other than those within the scope of its 
jurisdiction. In the interest of effective law enforcement, the OIG 
should retain this information because it may aid in establishing 
patterns of unlawful activity and provide leads for other law 
enforcement agencies. Further, in obtaining evidence during an 
investigation, information may be provided to the OIG which relates to 
matters incidental to the main purpose of the investigation but which 
may be pertinent to the investigative jurisdiction of another agency. 
Such information cannot readily be identified.
    (5) From subsection (e)(2), because in a law enforcement 
investigation it is usually counterproductive to collect information to 
the greatest extent practicable directly from the subject thereof. It is 
not always feasible to rely upon the subject of an investigation as a 
source for information which may implicate him or her in illegal 
activities. In addition, collecting information directly from the 
subject could seriously compromise an investigation by prematurely 
revealing its nature and scope, or could provide the subject with an 
opportunity to conceal criminal activities, or intimidate potential 
sources, in order to avoid apprehension.
    (6) From subsection (e)(3), because providing such notice to the 
subject of an investigation, or to other individual sources, could 
seriously compromise the investigation by prematurely revealing its 
nature and scope, or could inhibit cooperation, permit the subject to 
evade apprehension, or cause interference with undercover activities.
    (b) [Reserved]

[57 FR 62142, Dec. 29, 1992, as amended at 65 FR 50904, Aug. 21, 2000]



Sec. 2003.9  Specific exemptions.

    (a) The systems of records entitled ``Investigative Files of the 
Office of Inspector General,'' ``Hotline Complaint Files of the Office 
of Inspector General,'' ``Name Indices System of the Office of Inspector 
General,'' and ``AutoInvestigation of the Office of Inspector General'' 
consist, in part, of investigatory material compiled by the OIG for law 
enforcement purposes. Therefore, to the extent that information in these 
systems falls within the coverage of exemption (k)(2) of the Privacy 
Act, 5 U.S.C. 552a(k)(2), these systems of records are exempt from the 
requirements of the following subsections of the Privacy Act, for the 
reasons stated in paragraphs (a) (1) through (4) of this section.
    (1) From subsection (c)(3), because release of an accounting of 
disclosures to an individual who is the subject of an investigation 
could reveal the nature and scope of the investigation and could result 
in the altering or destruction of evidence, improper influencing of 
witnesses, and other evasive actions that could impede or compromise the 
investigation.
    (2) From subsection (d)(1), because release of investigative records 
to an individual who is the subject of an investigation could interfere 
with pending or prospective law enforcement proceedings, constitute an 
unwarranted invasion of the personal privacy of third parties, reveal 
the identity of

[[Page 18]]

confidential sources, or reveal sensitive investigative techniques and 
procedures.
    (3) From subsection (d)(2), because amendment or correction of 
investigative records could interfere with pending or prospective law 
enforcement proceedings, or could impose an impossible administrative 
and investigative burden by requiring the OIG to continuously retrograde 
its investigations attempting to resolve questions of accuracy, 
relevance, timeliness and completeness.
    (4) From subsection (e)(1), because it is often impossible to 
determine relevance or necessity of information in the early stages of 
an investigation. The value of such information is a question of 
judgment and timing; what appears relevant and necessary when collected 
may ultimately be evaluated and viewed as irrelevant and unnecessary to 
an investigation. In addition, the OIG may obtain information concerning 
the violation of laws other than those within the scope of its 
jurisdiction. In the interest of effective law enforcement, the OIG 
should retain this information because it may aid in establishing 
patterns of unlawful activity and provide leads for other law 
enforcement agencies. Further, in obtaining evidence during an 
investigation, information may be provided to the OIG which relates to 
matters incidental to the main purpose of the investigation but which 
may be pertinent to the investigative jurisdiction of another agency. 
Such information cannot readily be identified.
    (b) The systems of records entitled ``Investigative Files of the 
Office of Inspector General,'' ``Hotline Complaint Files of the Office 
of Inspector General,'' ``Name Indices System of the Office of Inspector 
General,'' and ``Autoinvestigation of the Office of Inspector General'' 
consist in part of investigatory material compiled by the OIG for the 
purpose of determining suitability, eligibility, or qualifications for 
Federal civilian employment or Federal contracts, the release of which 
would reveal the identity of a source who furnished information to the 
Government under an express promise that the identity of the source 
would be held in confidence. Therefore, to the extent that information 
in these systems fall within the coverage of exemption (k)(5) of the 
Privacy Act, 5 U.S.C. 552a(k)(5), these systems of records are exempt 
from the requirements of subsection (d)(1), because release would reveal 
the identity of a source who furnished information to the Government 
under an express promise of confidentiality. Revealing the identity of a 
confidential source could impede future cooperation by sources, and 
could result in harassment or harm to such sources.

    This subpart applies to demands and requests to employees for 
factual or expert testimony relating to official information, or for 
production of official records or information, in legal proceedings in 
which HUD or OIG is not a named party. However, this subpart does not 
apply to:
    (a) Demands upon or requests for an OIG employee to testify as to 
facts or events that are unrelated to his or her official duties or that 
are unrelated to the functions of OIG;
    (b) Requests for the release of records under the Freedom of

             Subpart B_Office of Inspector General Subpoenas



Sec. 2004.10  Service of an Office of Inspector General subpoena.

    Service of a subpoena issued by OIG may be accomplished as follows:
    (a) Personal service. Service may be made by delivering the subpoena 
to the person to whom it is addressed. If the subpoena is addressed to a 
corporation or other business entity, it may be served upon an employee 
of the corporation or entity. Service made to an employee, agent, or 
legal representative of the addressee shall constitute service upon the 
addressee.
    (b) Service by mail. Service may also be made by mailing the 
subpoena, certified mail--return receipt requested, to the addressee at 
his or her last known business or personal address.



      Subpart C_Requests for Testimony and Production of Documents



Sec. 2004.20  General prohibition.

    No employee may produce official records and information or provide 
any testimony relating to official information in response to a demand 
or request without the prior, written approval of the Inspector General 
or the Counsel.



Sec. 2004.21  Factors OIG will consider.

    The Counsel or Inspector General, in their discretion, may grant an 
employee permission to testify on matters relating to official 
information, or produce official records and information, in response to 
a demand or request. Among the relevant factors that the Inspector 
General or the Counsel may consider in making this decision are whether:
    (a) The purposes of this part are met;
    (b) OIG has an interest in the decision that may be rendered in the 
legal proceeding;
    (c) Allowing such testimony or production of records would assist or 
hinder OIG in performing its statutory duties or use OIG resources where 
responding to the request will interfere with the ability of OIG 
employees to do their work;
    (d) The records or testimony can be obtained from other sources;
    (e) The demand or request is unduly burdensome or otherwise 
inappropriate under the applicable rules of discovery or the rules of 
procedure governing the case or matter in which the demand or request 
arose;
    (f) Disclosure would violate or be inconsistent with a statute, 
Executive Order, or regulation;
    (g) Disclosure would reveal confidential or privileged information, 
trade secrets, or similar, confidential commercial, or financial 
information;
    (h) Disclosure would impede or interfere with an ongoing law 
enforcement investigation or proceedings, or compromise constitutional 
rights;
    (i) Disclosure would result in OIG appearing to favor one litigant 
over another;
    (j) Disclosure relates to documents that were produced by another 
agency;
    (k) The demand or request is in conformance with all other 
applicable rules;
    (l) The demand or request is sufficiently specific to be answered; 
and
    (m) For any other good cause.



Sec. 2004.22  Filing requirements for demands or requests for documents
or testimony.

    You must comply with the following requirements whenever you issue 
demands or requests to an OIG employee for official records and 
information or testimony.
    (a) Your request must be in writing and must be submitted to the 
Counsel. If you serve a subpoena on OIG or on an OIG employee before 
submitting a written request and receiving a final determination from 
the Counsel, OIG will oppose the subpoena on grounds that your request 
was not submitted in accordance with this subpart.
    (b) Your written request must contain the following information:
    (1) The caption of the legal proceeding, docket number, and name and 
address of the court or other authority involved;

[[Page 21]]

    (2) A copy of the complaint or equivalent document setting forth the 
assertions in the case and any other pleading or document sufficient to 
show relevance;
    (3) A list of categories of records sought, a detailed description 
of how the information sought is relevant to the issues in the legal 
proceeding, and a specific description of the substance of the testimony 
or records sought;
    (4) A statement as to how the need for the information outweighs the 
need to maintain any confidentiality of the information and outweighs 
the burden on OIG to produce the records or provide testimony;
    (5) A statement indicating that the information sought is not 
available from another source, from other persons or entities, or from 
the testimony of someone other than an OIG employee, such as a retained 
expert;
    (6) If testimony is requested, the intended use of the testimony, a 
general summary of the desired testimony, and a showing that no document 
could be provided and used in lieu of testimony;
    (7) A description of all prior decisions, orders, or pending motions 
in the case that bear upon the relevance of the requested records or 
testimony;
    (8) The name, address, and telephone number of counsel to each party 
in the case; and
    (9) An estimate of the amount of time that the requester and other 
parties will require with each OIG employee for time spent by the 
employee to prepare for testimony, in travel, and for attendance in the 
legal proceeding.
    (c) The OIG reserves the right to require additional information to 
complete your request where appropriate.
    (d) Your request should be submitted at least 30 days before the 
date that records or testimony are required. Requests submitted less 
than 30 days before records or testimony are required must be 
accompanied by a written explanation stating the reasons for the late 
request and the reasons for expedited processing.
    (e) Failure to cooperate in good faith to enable the Counsel to make 
an informed decision may serve as the basis for a determination not to 
comply with your request.



Sec. 2004.23  Service of subpoenas or requests.

    Subpoenas or requests for official records or information or 
testimony must be served on the Counsel to the Inspector General, Office 
of Inspector General, U.S. Department of Housing and Urban Development, 
451 Seventh Street, SW, Room 8260, Washington, DC 20410-4500.



Sec. 2004.24  Processing demands or requests.

    (a) After service of a demand or request to testify, the Counsel 
will review the demand or request and, in accordance with the provisions 
of this subpart, determine whether, or under what conditions, to 
authorize the employee to testify on matters relating to official 
information and/or to produce official records and information.
    (b) The OIG will process requests in the order in which they are 
received. Absent exigent or unusual circumstances, OIG will respond 
within 30 days from the date that we receive all information necessary 
to the evaluation of the demand or request. The time for response will 
depend upon the scope of the request.
    (c) The Counsel may grant a waiver of any procedure described in 
this subpart where a waiver is considered necessary to promote a 
significant interest of OIG, HUD, and the United States, or for other 
good cause.



Sec. 2004.25  Final determination.

    The Counsel makes the final determination on demands and requests to 
employees for production of official records and information or 
testimony. All final determinations are within the sole discretion of 
the Counsel. The Counsel will notify the requester of the final 
determination, the reasons for the grant or denial of the demand or 
request, and any conditions that the Counsel may impose on the release 
of records or information, or on the testimony of an OIG employee.



Sec. 2004.26  Restrictions that apply to testimony.

    (a) The Counsel may impose conditions or restrictions on the 
testimony of OIG employees including, for example, limiting the areas of 
testimony or

[[Page 22]]

requiring the requester and other parties to the legal proceeding to 
agree that the transcript of the testimony will be kept under seal or 
will only be used or made available in the particular legal proceeding 
for which testimony was requested. The Counsel may also require a copy 
of the transcript of testimony at the requester's expense.
    (b) The OIG may offer the employee's written declaration in lieu of 
testimony.
    (c) If authorized to testify pursuant to this part, an employee may 
testify as to facts within his or her personal knowledge, but, unless 
specifically authorized to do so by the Counsel, the employee shall not:
    (1) Disclose confidential or privileged information;
    (2) Testify as to facts when the Counsel determines such testimony 
would not be in the best interest of OIG, HUD and the United States; or
    (3) Testify as an expert or opinion witness with regard to any 
matter arising out of the employee's official duties or the functions of 
OIG. This provision does not apply to requests from the United States 
for expert or opinion testimony.



Sec. 2004.27  Restrictions that apply to released records.

    (a) The Counsel may impose conditions or restrictions on the release 
of official records and information, including the requirement that 
parties to the proceeding obtain a protective order or execute a 
confidentiality agreement to limit access and any further disclosure. 
The terms of the protective order or of a confidentiality agreement must 
be acceptable to the Counsel. In cases where protective orders or 
confidentiality agreements have already been executed, OIG may condition 
the release of official records and information on an amendment to the 
existing protective order or confidentiality agreement.
    (b) If the Counsel so determines, original OIG records may be 
presented for examination in response to a demand or request, but they 
are not to be presented as evidence or otherwise used in a manner by 
which they could lose their identity as official OIG records, nor are 
they to be marked or altered. In lieu of the original records, certified 
copies will be presented for evidentiary purposes.



Sec. 2004.28  Procedure in the event of an adverse ruling.

    (a) Opportunity to review adverse ruling. Any person aggrieved by a 
decision made by the Counsel under this part denying a request for 
documents or testimony, or restricting the release of documents or 
testimony, may seek review of that decision pursuant to paragraph (c) of 
this section.
    (b) Procedure in the event of conflicting court order. If the 
Inspector General or Counsel declines to approve a demand for records or 
testimony and a court or other authority rules that the demand must be 
complied with irrespective of the instructions from the OIG not to 
produce the material or disclose the information sought, the employee or 
former employee upon whom the demand has been made shall respectfully 
decline to comply with the demand, citing United States ex rel. Touhy v. 
Ragen, 340 U.S. 462 (1951).
    (c) Procedure--(1) Notice of intention to petition for review. A 
party or any person aggrieved by the decision made pursuant to this part 
denying or restricting the release of documents or testimony may seek 
review of the decision by filing a written Notice of Intention to 
Petition for Review (Notice) within five business days of the date of 
this decision. The Notice shall identify the petitioner, the adverse 
decision, and any dates (such as deposition, hearing, or court dates) 
that are significant to the party. The Notice shall be served in 
accordance with Sec. 2004.23.
    (2) Petition for review. Within five business days of the filing of 
a Notice, the person or party seeking review shall file a Petition for 
Review (Petition) containing a clear and concise statement of the issues 
to be reviewed and the reasons why the review is appropriate. The 
petition shall include exceptions to any findings of fact or conclusions 
of law made, together with supporting reasons and arguments for such 
exceptions based on appropriate citations to such record or law as may 
exist. These reasons may be stated in

[[Page 23]]

summary form. Decisions on the Petition may be made by either the 
Inspector General or the Counsel and shall become the final decisions of 
the OIG. The Petition will be served in accordance with Sec. 2004.23.
    (d) Prerequisite to judicial review. Pursuant to Section 704 of the 
Administrative Procedure Act, 5 U.S.C. 704, a petition to the agency for 
review of a decision made under the authority of this part is a 
prerequisite to the seeking of judicial review of the final decision.

[70 FR 36791, June 24, 2005]



Sec. 2004.29  Fees.

    (a) Generally. The Counsel may condition the production of records 
or appearance for testimony upon advance payment of a reasonable 
estimate of the costs to OIG.
    (b) Fees for records. Fees for producing records will include fees 
for searching, reviewing, and duplicating records, costs of attorney 
time spent in reviewing the demand or request, and expenses generated by 
materials and equipment used to search for, produce, and copy the 
responsive information. Costs for employee time will be calculated on 
the basis of the hourly pay of the employee (including all pay, 
allowance, and benefits). Fees for duplication will be the same as those 
charged by OIG in its Freedom of Information Act Regulations at 24 CFR 
part 2002.
    (c) Witness fees. Fees for attendance by a witness will include 
fees, expenses, and allowances prescribed by the court's rules. If no 
such fees are prescribed, witness fees will be determined based upon the 
rule of the federal district court closest to the location where the 
witness will appear. Such fees will include cost of time spent by the 
witness to prepare for testimony, in travel, and for attendance in the 
legal proceeding.
    (d) Payment of fees. You must pay any applicable witness fees for 
current OIG employees and any records certification fees by submitting 
to the Counsel a check or money order for the appropriate amount made 
payable to the Treasury of the United States. In the case of testimony 
by former OIG employees, you must pay applicable fees directly to the 
former employee in accordance with applicable statutes.
    (e) Waiver or reduction of fees. The Counsel, in his or her sole 
discretion, may, upon a showing of reasonable cause, waive or reduce any 
fees in connection with the testimony or production of records. 
Additionally, fees will not be assessed if the total charge would be 
$10.00 or less.

                            Subpart A_General



Sec. 3280.1  Scope.

    This standard covers all equipment and installations in the design, 
construction, transportation, fire safety, plumbing, heat-producing and 
electrical systems of manufactured homes which are designed to be used 
as dwelling units. This standard seeks to the maximum extent possible to 
establish performance requirements. In certain instances, however, the 
use of specific requirements is necessary.

[58 FR 55002, Oct. 25, 1993]



Sec. 3280.2  Definitions.

    Definitions in this subpart are those common to all subparts of the 
standard and are in addition to the definitions provided in individual 
parts. The definitions are as follows:
    Approved, when used in connection with any material, appliance or 
construction, means complying with the requirements of the Department of 
Housing and Urban Development.
    Bay window--a window assembly whose maximum horizontal projection is 
not more than two feet from the plane of an exterior wall and is 
elevated above the floor level of the home.
    Certification label means the approved form of certification by the 
manufacturer that, under Sec. 3280.8, is permanently affixed to each 
transportable section of each manufactured home manufactured for sale in 
the United States.
    Dwelling unit means one or more habitable rooms which are designed 
to be occupied by one family with facilities for living, sleeping, 
cooking and eating.
    Equipment includes materials, appliances, devices, fixtures, 
fittings or accessories both in the construction of, and in the fire 
safety, plumbing, heat-producing and electrical systems of manufactured 
homes.
    Federal manufactured home construction and safety standard means a 
reasonable standard for the construction, design, and performance of a 
manufactured home which meets the needs of the public including the need 
for quality, durability, and safety.
    Installations means all arrangements and methods of construction, as 
well as fire safety, plumbing, heat-producing and electrical systems 
used in manufactured homes.
    Labeled means a label, symbol or other identifying mark of a 
nationally recognized testing laboratory, inspection agency, or other 
organization concerned with product evaluation that maintains periodic 
inspection of production of labeled equipment or materials, and by whose 
labeling is indicated compliance with nationally recognized standards or 
tests to determine suitable usage in a specified manner.
    Length of a manufactured home means its largest overall length in 
the traveling mode, including cabinets and other projections which 
contain interior space. Length does not include bay windows, roof 
projections, overhangs,

[[Page 31]]

or eaves under which there is no interior space, nor does it include 
drawbars, couplings or hitches.
    Listed or certified means included in a list published by a 
nationally recognized testing laboratory, inspection agency, or other 
organization concerned with product evaluation that maintains periodic 
inspection of production of listed equipment or materials, and whose 
listing states either that the equipment or material meets nationally 
recognized standards or has been tested and found suitable for use in a 
specified manner.
    Manufacturer means any person engaged in manufacturing or assembling 
manufactured homes, including any person engaged in importing 
manufactured homes for resale.
    Manufactured home means a structure, transportable in one or more 
sections, which in the traveling mode is 8 body feet or more in width or 
40 body feet or more in length or which when erected on-site is 320 or 
more square feet, and which is built on a permanent chassis and designed 
to be used as a dwelling with or without a permanent foundation when 
connected to the required utilities, and includes the plumbing, heating, 
air-conditioning, and electrical systems contained in the structure. 
This term includes all structures that meet the above requirements 
except the size requirements and with respect to which the manufacturer 
voluntarily files a certification pursuant to Sec. 3282.13 of this 
chapter and complies with the construction and safety standards set 
forth in this part 3280. The term does not include any self-propelled 
recreational vehicle. Calculations used to determine the number of 
square feet in a structure will include the total of square feet for 
each transportable section comprising the completed structure and will 
be based on the structure's exterior dimensions measured at the largest 
horizontal projections when erected on site. These dimensions will 
include all expandable rooms, cabinets, and other projections containing 
interior space, but do not include bay windows. Nothing in this 
definition should be interpreted to mean that a manufactured home 
necessarily meets the requirements of HUD's Minimum Property Standards 
(HUD Handbook 4900.1) or that it is automatically eligible for financing 
under 12 U.S.C. 1709(b).
    Manufactured home construction means all activities relating to the 
assembly and manufacture of a manufactured home including, but not 
limited to, those relating to durability, quality and safety.
    Manufactured home safety means the performance of a manufactured 
home in such a manner that the public is protected against any 
unreasonable risk of the occurrence of accidents due to the design or 
construction of such manufactured home, or any unreasonable risk of 
death or injury to the user or to the public if such accidents do occur.
    Registered Engineer or Architect means a person licensed to practice 
engineering or architecture in a state and subject to all laws and 
limitations imposed by the state's Board of Engineering and Architecture 
Examiners and who is engaged in the professional practice of rendering 
service or creative work requiring education, training and experience in 
engineering sciences and the application of special knowledge of the 
mathematical, physical and engineering sciences in such professional or 
creative work as consultation, investigation, evaluation, planning or 
design and supervision of construction for the purpose of securing 
compliance with specifications and design for any such work.
    Secretary means the Secretary of Housing and Urban Development, or 
an official of the Department delegated the authority of the Secretary 
with respect to title VI of Pub. L. 93-383.
    State includes each of the several States, the District of Columbia, 
the Commonwealth of Puerto Rico, Guam, the Virgin Islands, the Canal 
Zone, and American Samoa.
    Width of a manufactured home means its largest overall width in the 
traveling mode, including cabinets and other projections which contain 
interior space. Width does not include bay windows, roof projections, 
overhangs,

[[Page 32]]

                    Subpart B_Planning Considerations



Sec. 3280.101  Scope.

    Subpart B states the planning requirements in manufactured homes. 
The intent of this subpart is to assure the adequacy of architectural 
planning considerations which assist in determining a safe and healthful 
environment.



Sec. 3280.102  Definitions.

    (a) Gross floor area means all space, wall to wall, including 
recessed entries not to exceed 5 sq. ft. and areas under built-in 
vanities and similar furniture. Where the ceiling height is less than 
that specified in Sec. 3280.104, the floor area under such ceilings 
shall not be included. Floor area of closets shall not be included in 
the gross floor area.
    (b) Habitable room means a room or enclosed floor space arranged for 
living, eating, food preparation, or sleeping purposes not including 
bathrooms, foyers, hallways, and other accessory floor space.
    (c) Laundry area means an area containing or designed to contain a 
laundry tray, clothes washer and/or clothes dryer.



Sec. 3280.103  Light and ventilation.

    (a) Lighting. Each habitable room shall be provided with exterior 
windows and/or doors having a total glazed area of not less than 8 
percent of the gross floor area.
    (1) Kitchens, bathrooms, toilet compartments, laundry areas, and 
utility rooms may be provided with artificial light in place of windows.
    (2) Rooms and areas may be combined for the purpose of providing the 
required natural lighting provided that at least one half of the common 
wall area is open and unobstructed, and the open area is at least equal 
to 10 percent of the combined floor area or 25 square feet whichever is 
greater.

[[Page 44]]

    (b) Whole-house ventilation. Each manufactured home must be provided 
with whole-house ventilation having a minimum capacity of 0.035 ft\3\/
min/ft\2\ of interior floor space or its hourly average equivalent. This 
ventilation capacity must be in addition to any openable window area. In 
no case shall the installed ventilation capacity of the system be less 
than 50 cfm nor more than 90 cfm. The following criteria must be adhered 
to:
    (1) The ventilation capacity must be provided by a mechanical system 
or a combination passive and mechanical system. The ventilation system 
or provisions for ventilation must not create a positive pressure in Uo 
Value Zone 2 and Zone 3 or a negative pressure condition in Uo Value 
Zone 1. Mechanical systems must be balanced. Combination passive and 
mechanical systems must have adequately sized inlets or exhaust to 
release any unbalanced pressure. Temporary pressure imbalances due to 
gusting or high winds are permitted.
    (2) The ventilation system or provisions for ventilation must 
exchange air directly with the exterior of the home, except the 
ventilation system, or provisions for ventilation must not draw or expel 
air with the space underneath the home. The ventilation system or 
provisions for ventilation must not draw or expel air into the floor, 
wall, or ceiling/roof systems, even if those systems are vented. The 
ventilation system must be designed to ensure that outside air is 
distributed to all bedrooms and main living areas. The combined use of 
undercut doors or transom grills connecting those areas to the room 
where the mechanical system is located is deemed to meet this 
requirement.
    (3) The ventilation system or a portion of the system is permitted 
to be integral with the home's heating or cooling system. The system 
must be capable of operating independently of the heating or cooling 
modes. A ventilation system that is integral with the heating or cooling 
system is to be listed as part of the heating and cooling system or 
listed as suitable for use with that system.
    (4) A mechanical ventilation system, or mechanical portion thereof, 
must be provided with a manual control, and must be permitted to be 
provided with automatic timers or humidistats.
    (5) A whole-house ventilation label must be attached to the whole-
house ventilation control, must be permanent, and must state: ``WHOLE-
HOUSE VENTILATION''.
    (6) Instructions for correctly operating and maintaining whole-house 
ventilation systems must be included with the homeowner's manual. The 
instructions must encourage occupants to operate these systems whenever 
the home is occupied, and must refer to the labeled whole-house 
ventilation control.
    (c) Additional ventilation. (1) At least half of the minimum 
required glazed area in paragraph (a) of this section shall be openable 
directly to the outside of the manufactured home for unobstructed 
ventilation. These same ventilation requirements apply to rooms combined 
in accordance with Sec. 3280.103(a)(2).
    (2) Kitchens shall be provided with a mechanical ventilation system 
that is capable of exhausting 100 cfm to the outside of the home. The 
exhaust fan shall be located as close as possible to the range or cook 
top, but in no case farther than 10 feet horizontally from the range or 
cook top.
    (3) Each bathroom and separate toilet compartment shall be provided 
with a mechanical ventilation system capable of exhausting 50 cfm to the 
outside of the home. A separate toilet compartment may be provided with 
1.5 square feet of openable glazed area in place of mechanical 
ventilation, except in Uo value Zone 3.

[58 FR 55003, Oct. 25, 1993, as amended at 70 FR 72042, Nov. 30, 2005]



Sec. 3280.104  Ceiling heights.

    (a) Every habitable room and bathroom shall have a minimum ceiling 
height of not less than 7 feet, 0 inches for a minimum of 50 percent of 
the room's floor area. The remaining area may have a ceiling with a 
minimum height of 5 feet, 0 inches. Minimum height under dropped ducts, 
beams, etc. shall be 6 feet, 4 inches.
    (b) Hallways and foyers shall have a minimum ceiling height of 6 
feet, 6 inches.

length of path of travel between doors.
    (iii) Double wide units. Doors may not be less than 20 ft. c-c from 
each other as measured in any straight line direction regardless of the 
length of path of travel between doors.
    (iv) One of the required exit doors must be accessible from the 
doorway of each bedroom without traveling more than 35 feet. The travel 
distance to the exit door must be measured on the floor or other walking 
surface along the center-line of the natural and unobstructed path of 
travel starting at the center of the bedroom door, curving around any 
corners or permanent obstructions with a one-foot clearance from, and 
ending at, the center of the exit door.

successfully tested in accordance with this paragraph.
    (2) Home manufacturers must provide specific written instructions 
for installers on how to inspect and test the operation of smoke alarms 
during installation of the home. These instructions must indicate that 
any smoke alarm that does not meet the inspection or testing 
requirements needs to be replaced and retested.
    (3) Home manufacturers must provide the homeowner with the alarm 
manufacturer's information describing the operation, method and 
frequency of testing, and proper maintenance of the smoke alarm. This 
information must be provided in same manner and location as the consumer 
manual required by Sec. 3282.207 of this chapter, but does not have to 
be incorporated into the consumer manual. No dealer, distributor, 
construction contractor, or other person shall interfere with the 
distribution of this information

Sec. 3280.305  Structural design requirements.

    (a) General. Each manufactured home shall be designed and 
constructed as a completely integrated structure capable of sustaining 
the design load requirements of this standard, and shall be capable of 
transmitting these loads to stabilizing devices without exceeding the 
allowable stresses or deflections. Roof framing shall be securely 
fastened to wall framing, walls to floor structure, and floor structure 
to chassis to secure and maintain continuity between the floor and 
chassis, so as to resist wind overturning, uplift, and sliding as 
imposed by design loads in this part. Uncompressed finished flooring 
greater than \1/8\ inch in thickness shall not extend beneath load-
bearing walls that are fastened to the floor structure.
    (b) Design loads--(1) Design dead loads. Design dead loads shall be 
the actual dead load supported by the structural assembly under 
consideration.
    (2) Design live loads. The design live loads and wind and snow loads 
shall be as specified in this section and shall be considered to be 
uniformly distributed. The roof live load or snow load shall not be 
considered as acting simultaneously with the wind load and the roof live 
or snow load and floor live loads shall not be considered as resisting 
the overturning moment due to wind.
    (3) When engineering calculations are performed, allowable unit 
stresses may be increased as provided in the documents referenced in 
Sec. 3280.304 except as otherwise indicated in Sec. Sec. 
3280.304(b)(1) and 3280.306(a).
    (4) Whenever the roof slope does not exceed 20 degrees, the design 
horizontal wind loads required by Sec. 3280.305(c)(1) may be determined 
without including the vertical roof projection of the manufactured home. 
However, regardless of the roof slope of the manufactured home, the 
vertical roof projection shall be included when determining the wind 
loading for split level or clerestory-type roof systems.
    (c) Wind, snow, and roof loads--(1) Wind loads--design requirements. 
(i) Standard wind loads (Zone I). When a manufactured home is not 
designed to resist the wind loads for high-wind areas (Zone II or Zone 
III) specified in paragraph (c)(1)(ii) of this section, the manufactured 
home and each of its wind-resisting parts and portions must be designed 
for horizontal wind loads of not less than 15 psf and a net uplift roof 
load of not less than 9 psf. The net uplift roof load must not be 
reduced by the dead load of the roof structure for the purposes of 
engineering design or structural load testing.
    (ii) Wind loads for high wind areas (Zone II and Zone III). When 
designed for high wind areas (Zone II and Zone III), the manufactured 
home, each of its wind resisting parts (including, but not limited to, 
shear walls, diaphragms, ridge beams, and their fastening and anchoring 
systems), and its components and cladding materials (including, but not 
limited to, roof trusses, wall studs, exterior sheathing, roofing and 
siding materials, exterior glazing, and their connections and fasteners) 
shall be designed by a Professional Engineer or Architect to resist:
    (A) The design wind loads for Exposure C specified in ANSI/ASCE 7-
88, ``Minimum Design Loads for Buildings and Other Structures,'' for a 
fifty-year

------------------------------------------------------------------------
NOTES:
 
\1\ The net horizontal drag of 39 PSF to be used
  in calculating Anchorage for Lateral and Vertical Stability and for
  the design of Main Wind Force Resisting Systems is based on a
  distribution of wind pressures of +0.8 or +24 PSF to the windward wall
  and -0.5 or -15 PSF to the leeward wall.
\2\ Horizontal drag pressures need not be applied to roof projections
  when the roof slope does not exceed 20 degrees.
\3\ + sign would mean pressures are acting towards or on the structure;
   sign means pressures are acting away from the structure; sign means forces can act in either direction, towards
  or away from the structure.
\4\ Design values in this ``Table'' are only applicable to roof slopes
  between 10 degrees (nominal 2/12 slope) and 30 degrees.
\5\ The design uplift pressures are the same whether they are applied
  normal to the surface of the roof or to the horizontal projection of
  the roof.
\6\ Shingle roof coverings that are secured with 6 fasteners per shingle
  through an underlayment which is cemented to a 3/8'' structural rated
  roof sheathing need not be evaluated for these design wind pressures.
\7\ Structural rated roof sheathing that is at least 3/8'' in thickness,
  installed with the long dimension perpendicular to roof framing
  supports, and secured with fasteners at 4'' on center within 3[foot]-
  0[foot] of each gable end or endwall if no overhang is provided and
  6'' on center in all other areas, need not be evaluated for these
  design wind pressures.
\8\ Exterior coverings that are secured at 6 o.c. to a 3/8 structural rated sheathing that is fastened to wall framing
  members at 6 on center need not be evaluated for these
  design wind pressures.

    (iii) One-piece metal roofing capable of resisting the design wind 
pressures for ``Components and Cladding: (Exterior roof coverings)'' in 
the Table for Design Wind Pressures in this section is allowed to be 
used without structural sheathing, provided the metal roofing is tested 
using procedures that have been approved by HUD and that meet all 
requirements of Sec. Sec. 3280.303(c) and (g) and 3280.401.
    (2) Wind loads--zone designations. The Wind Zone and specific wind 
design load requirements are determined by the fastest basic wind speed 
(mph) within each Zone and the intended location, based on the Basic 
Wind Zone Map, as follows:
    (i) Wind Zone I. Wind Zone I consists of those areas on the Basic 
Wind Zone Map that are not identified in paragraphs (c)(2)(ii) or (iii) 
of this section as being within Wind Zone II or III, respectively.
    (ii) Wind Zone II.....100 mph. The following areas are deemed to be 
within Wind Zone II of the Basic Wind Zone Map:

    Local governments: The following local governments listed by State 
(counties, unless specified otherwise):
    Alabama: Baldwin and Mobile.

    (C) South Roof Load Zone. The states and counties that are not 
listed for the North Roof Load Zone in paragraph

[[Page 60]]

(c)(3)(i)(A) of this section, or the Middle Roof Load Zone in paragraph 
(c)(3)(i)(B) of this section, are deemed to be within the South Roof 
Load Zone.
    (ii) Consideration of local requirements. For exposures in areas 
(mountainous or other) where recognized snow records, wind records, or 
the requirements of the State or local authority indicate significant 
differences from the loads stated in this paragraph (c)(3), the 
Department may establish, through rulemaking, more stringent 
requirements for manufactured homes to be installed in such areas. For 
snow loads, such requirements must be based on a roof snow load of 0.6 
of the ground snow load for areas exposed to wind and a roof snow load 
of 0.8 of the ground snow load for sheltered areas.
    (iii) Eaves and cornices shall be designed for a net uplift pressure 
of 2.5 times the design uplift wind pressure cited in Sec. 
3280.305(c)(1)(i) for Wind Zone I, and for the design pressures cited in 
Sec. 3280.305(c)(1)(ii) for Wind Zones II and III.
    (iv) Skylights must be capable of withstanding roof loads as 
specified in paragraphs (c)(3)(i) or (c)(3)(ii) of this section. 
Skylights must be listed and tested in accordance with AAMA 1600/I.S.7-
00, 2003, Voluntary Specification for Skylights.
    (4) Data plate requirements. The Data Plate posted in the 
manufactured home (see Sec. 3280.5) shall designate the wind and roof 
load zones or, if designed for higher loads, the actual design external 
snow and wind loads for which the home has been designed. The Data Plate 
shall include reproductions of the Load Zone Maps shown in this 
paragraph (c)(4), with any related information. The Load Zone Maps shall 
be not less than either 3\1/2\ in. by 2\1/4\ in., or one-half the size 
illustrated in the Code of Federal Regulations.

    (d) Design load deflection. (1) When a structural assembly is 
subjected to total design live loads, the deflection for structural 
framing members shall not exceed the following (where L equals the clear 
span between supports or two times the length of a cantilever):


[[Page 63]]


Floor--L/240
Roof and ceiling--L/180
Headers, beams, and girders (vertical load)--L/180
Walls and partitions--L/180

    (2) The allowable eave or cornice deflection for uplift is to be 
measured at the design uplift load of 9 psf for Wind Zone I, and at the 
design uplift pressure cited in paragraph (c)(1)(ii) of this section for 
Wind Zones II and III. The allowable deflection shall be (2xLc)/180, 
where Lc is the measured horizontal eave projection from the wall.
    (e) Fastening of structural systems. (1) Roof framing must be 
securely fastened to wall framing, walls to floor structure, and floor 
structure to chassis, to secure and maintain continuity between the 
floor and chassis in order to resist wind overturning, uplift, and 
sliding, and to provide continuous load paths for these forces to the 
foundation or anchorage system. The number and type of fasteners used 
must be capable of transferring all forces between elements being 
joined.
    (2) For Wind Zone II and Wind Zone III, roof framing members must be 
securely fastened at the vertical bearing points to resist design 
overturning, uplift, and sliding forces. When engineered connectors are 
not installed, roof framing members must be secured at the vertical 
bearing points to wall framing members (studs), and wall framing members 
(studs) must be secured to floor framing members, with 0.016 inch base 
metal, minimum steel strapping or engineered connectors, or by a 
combination of 0.016 inch base metal, minimum steel strapping or 
engineered connectors, and structural-rated wall sheathing that overlaps 
the roof and floor system if substantiated by structural analysis or by 
suitable load tests. Steel strapping or engineered connectors are to be 
installed at a maximum spacing of 24 inches on center in Wind Zone II, 
and 16 inches on center in Wind Zone III. Exception: Where substantiated 
by structural analysis or suitable load tests, the 0.016 inch base metal 
minimum steel strapping or engineered connectors may be omitted at the 
roof to wall and/or wall to floor connections, when structural rated 
sheathing that overlaps the roof and wall and/or wall and floor is 
capable of resisting the applicable design wind loads.
    (f) Walls. The walls shall be of sufficient strength to withstand 
the load requirements as defined in Sec. 3280.305(c) of this part, 
without exceeding the deflections as specified in Sec. 3280.305(d). The 
connections between the bearing walls, floor, and roof framework members 
shall be fabricated in such a manner as to provide support for the 
material used to enclose the manufactured home and to provide for 
transfer of all lateral and vertical loads to the floor and chassis.
    (1) Except where substantiated by engineering analysis or tests, 
studs shall not be notched or drilled in the middle one-third of their 
length.
    (2) Interior walls and partitions shall be constructed with 
structural capacity adequate for the intended purpose and shall be 
capable of resisting a horizontal load of not less than five pounds per 
square foot. An allowable stress increase of 1.33 times the permitted 
published design values may be used in the design of wood framed 
interior partitions. Finish of walls and partitions shall be securely 
fastened to wall framing.
    (g) Floors. (1) Floor assemblies shall be designed in accordance 
with accepted engineering practice standards to support a minimum 
uniform live load of 40 lb/ft \2\ plus the dead load of the materials. 
In addition (but not simultaneously), floors shall be able to support a 
200-pound concentrated load on a one-inch diameter disc at the most 
critical location with a maximum deflection not to exceed one-eighth 
inch relative to floor framing. Perimeter wood joists of more than six 
inches depth shall be stabilized against overturning from superimposed 
loads as follows: at ends by solid blocking not less than two-inch 
thickness by full depth of joist, or by connecting to a continuous 
header not less than two-inch thickness and not less than the depth of 
the joist with connecting devices; at eight-feet maximum intermediate 
spacing by solid blocking or by wood cross-bridging of not less than one 
inch by three inches, metal cross-bridging of equal strength, or by 
other approved methods.

[[Page 64]]

    (2) Wood, wood fiber or plywood floors or subfloors in kitchens, 
bathrooms (including toilet compartments), laundry areas, water heater 
compartments, and any other areas subject to excessive moisture shall be 
moisture resistant or shall be made moisture resistant by sealing or by 
an overlay of nonabsorbent material applied with water-resistant 
adhesive. Use of one of the following methods would meet this 
requirement:
    (i) Sealing the floor with a water-resistant sealer; or
    (ii) Installing an overlay of a non-absorbent floor covering 
material applied with water-resistant adhesive; or
    (iii) Direct application of a water-resistant sealer to the exposed 
wood floor area when covered with a non-absorbent overlay; or
    (iv) The use of a non-absorbent floor covering which may be 
installed without a continuous application of a water-resistant adhesive 
or sealant when the floor covering meets the following criteria:
    (A) The covering is a continuous membrane with any seams or patches 
seam bonded or welded to preserve the continuity of the floor covering; 
and
    (B) The floor is protected at all penetrations in these areas by 
sealing with a compatible water-resistant adhesive or sealant to prevent 
moisture from migrating under the nonabsorbent floor covering; and
    (C) The covering is fastened around the perimeter of the subfloor in 
accordance with the floor covering manufacturer's instructions; and,
    (D) The covering is designed to be installed to prevent moisture 
penetration without the use of a water-resistant adhesive or sealer 
except as required in this paragraph (g). The vertical edges of 
penetrations for plumbing shall be covered with a moisture-resistant 
adhesive or sealant. The vertical penetrations located under the bottom 
plates of perimeter walls of rooms, areas, or compartments are not 
required to be sealed; this does not include walls or partitions within

Sec. 3280.306  Windstorm protection.

    (a) Provisions for support and anchoring systems. Each manufactured 
home shall have provisions for support/anchoring or foundation systems 
that, when properly designed and installed, will resist overturning and 
lateral movement (sliding) of the manufactured home as imposed by the 
respective design loads. For Wind Zone I, the design wind loads to be 
used for calculating resistance to overturning and lateral movement 
shall be the simultaneous application of the wind loads indicated in 
Sec. 3280.305(c)(1)(i), increased by a factor of 1.5. The 1.5 factor of 
safety for Wind Zone I is also to be applied simultaneously to both the 
vertical building projection, as horizontal wind load, and across the 
surface of the full roof structure, as uplift loading. For Wind Zones II 
and III, the resistance shall be determined by the simultaneous 
application of the horizontal drag and uplift wind loads, in accordance 
with Sec. 3280.305(c)(1)(ii). The basic allowable stresses of materials 
required to resist overturning and lateral movement shall not be 
increased in the design and proportioning of these members. No 
additional shape or location factors need to be applied in the design of 
the tiedown system. The dead load of the structure may be used to resist 
these wind loading effects in all Wind Zones.
    (1) The provisions of this section shall be followed and the support 
and anchoring systems shall be designed by a Registered Professional 
Engineer or Architect.
    (2) The manufacturer of each manufactured home is required to make 
provision for the support and anchoring systems but is not required to 
provide the anchoring equipment or stabilizing devices. When the 
manufacturer's installation instructions provide for the

[[Page 66]]

main frame structure to be used as the points for connection of diagonal 
ties, no specific connecting devices need be provided on the main frame 
structure.
    (b) Contents of instructions. (1) The manufacturer must provide 
printed instructions with each manufactured home that specify the 
location and required capacity of stabilizing devices on which the 
home's design is based. The manufacturer must identify by paint, label, 
decal stencil, or other means: the location of each column support pier 
location required along the marriage line(s) of multi-section 
manufactured homes; each pier location required along the perimeter of 
the home; each required shear wall pier support; and any other special 
pier support locations specified in the manufacturer's printed 
instructions. Such identifications must be visible after the home is 
installed. The manufacturer must provide drawings and specifications, 
certified by a registered professional engineer or architect, that 
indicate at least one acceptable system of anchoring, including the 
details or required straps or cables, their end connections, and all 
other devices needed to transfer the wind loads from the manufactured 
home to an anchoring or foundation system.
    (2) For anchoring systems, the instructions shall indicate:
    (i) The minimum anchor capacity required;
    (ii) That anchors should be certified by a professional engineer, 
architect, or a nationally recognized testing laboratory as to their 
resistance, based on the maximum angle of diagonal tie and/or vertical 
tie loading (see paragraph (c)(3) of this section) and angle of anchor 
installation, and type of soil in which the anchor is to be installed;
    (iii) That ground anchors are to be embedded below the frost line, 
unless the foundation system is frost-protected in accordance with 
Sec. Sec. 3285.312(b) and 3285.404 of the Model Manufactured Home 
Installation Standards in this chapter.
    (iv) That ground anchors must be installed to their full depth, and 
stabilizer plates must be installed in accordance with the ground anchor 
listing or certification to provide required resistance to overturning 
and sliding.
    (v) That anchoring equipment should be certified by a registered 
professional engineer or architect to resist these specified forces in 
accordance with testing procedures in ASTM D3953-97, Standard 
Specification for Strapping, Flat Steel and Seals (incorporated by 
reference, see Sec. 3280.4).
    (c) Design criteria. The provisions made for anchoring systems shall 
be based on the following design criteria for manufactured homes.
    (1) The minimum number of ties provided per side of each home shall 
resist design wind loads required in Sec. 3280.305(c)(1).
    (2) Ties shall be as evenly spaced as practicable along the length 
of the manufactured home, with not more than two (2) feet open-end 
spacing on each end.
    (3) Vertical ties or straps shall be positioned at studs. Where a 
vertical tie and a diagonal tie are located at the same place, both ties 
may be connected to a single anchor, provided that the anchor used is 
capable of carrying both loadings, simultaneously.
    (4) Add-on sections of expandable manufactured homes shall have 
provisions for vertical ties at the exposed ends.
    (d) Requirements for ties. Manufactured homes in Wind Zone I require 
only diagonal ties. These ties shall be placed along the main frame and 
below the outer side walls. All manufactured homes designed to be 
located in Wind Zones II and III shall have a vertical tie installed at 
each diagonal tie location.
    (e) Protection requirements. Protection shall be provided at sharp 
corners where the anchoring system requires the use of external straps 
or cables. Protection shall also be provided to minimize damage to 
siding by the cable or strap.
    (f) Anchoring equipment--load resistance. Anchoring equipment shall 
be capable of resisting an allowable working load equal to or exceeding 
3,150 pounds and shall be capable of withstanding a 50 percent overload 
(4,725 pounds total) without failure of either the anchoring equipment 
or the attachment point on the manufactured home.
    (g) Anchoring equipment--weatherization. Anchoring equipment exposed 
to

[[Page 67]]

weathering shall have a resistance to weather deterioration at least 
equivalent to that provided by a coating of zinc on steel of not less 
than 0.30 ounces per square foot of surface coated, and in accordance 
with the following:
    (1) Slit or cut edges of zinc-coated steel strapping do not need to 
be zinc coated.
    (2) Type 1, Finish B, Grade 1 steel strapping, 1\1/4\ inches wide 
and 0.035 inches in thickness, certified by a registered professional 
engineer or architect as conforming with ASTM D3953-97, Standard 
Specification for Strapping, Flat Steel and Seals (incorporated by 
reference, see Sec. 3280.4).

Sec. 3280.307  Resistance to elements and use.

    (a) Exterior coverings shall be of moisture and weather resistive 
materials attached with corrosion resistant fasteners to resist wind, 
snow and rain. Metal coverings and exposed metal structural members 
shall be of corrosion resistant materials or shall be protected to 
resist corrosion. All joints between portions of the exterior covering 
shall be designed, and assembled to protect against the infiltration of 
air and water, except for any designed ventilation of wall or roof 
cavity.
    (b) Joints between dissimilar materials and joints between exterior 
coverings and frames of openings shall be protected with a compatible 
sealant suitable to resist infiltration of air or water.
    (c) Where adjoining materials or assemblies of materials are of such 
nature that separation can occur due to expansion, contraction, wind 
loads or other loads induced by erection or transportation, sealants 
shall be of a type that maintains protection against infiltration or 
penetration by air, moisture or vermin.
    (d) Exterior surfaces shall be sealed to resist the entrance of 
rodents.



Sec. 3280.308  Formaldehyde emission controls for certain wood products.

    (a) Formaldehyde emission levels. All plywood and particleboard 
materials bonded with a resin system or coated with a surface finish 
containing formaldehyde shall not exceed the following formaldehyde 
emission levels when installed in manufactured homes:
    (1) Plywood materials shall not emit formaldehyde in excess of 0.2 
parts per million (ppm) as measured by the air chamber test method 
specified in Sec. 3280.406.
    (2) Particleboard materials shall not emit formaldehyde in excess of 
0.3 ppm as measured by the air chamber test specified in Sec. 3280.406.
    (b) Product certification and continuing qualification. All plywood 
and particleboard materials to be installed in manufactured homes which 
are bonded with a resin system or coated with a surface finish 
containing formaldehyde, other than an exclusively phenol-formaldehyde 
resin system or finish, shall be certified by a nationally recognized 
testing laboratory as complying with paragraph (a) of this section.
    (1) Separate certification shall be done for each plant where the 
particleboard is produced or where the plywood or particleboard is 
surface-finished.
    (2) To certify plywood or particleboard, the testing laboratory 
shall witness or conduct the air chamber test specified in Sec. 
3280.406 on randomly selected panels initially and at least quarterly 
thereafter.
    (3) The testing laboratory must approve a written quality control 
plan for each plant where the particleboard is produced or finished or 
where the plywood is finished. The quality control plan must be designed 
to assure that all panels comply with paragraph (a) of this section. The 
plan must establish ongoing procedures to identify increases in the 
formaldehyde emission characteristics of the finished product resulting 
from the following changes in production.
    (i) In the case of plywood:
    (A) The facility where the unfinished panels are produced is 
changed;

[[Page 68]]

    (B) The thickness of the panels is changed so that the panels are 
thinner; or
    (C) The grooving pattern on the panels is changed so that the 
grooves are deeper or closer together.
    (ii) In the case of particleboard:
    (A) The resin formulation is changed so that the formaldehyde-to-
urea ratio is increased;
    (B) The amount of formaldehyde resin used is increased; or
    (C) The press time is decreased.
    (iii) In the case of plywood or particleboard:
    (A) The finishing or top coat is changed and the new finishing or 
top coat has a greater formaldehyde content; or
    (B) The amount of finishing or top coat used on the panels is 
increased, provided that such finishing or top coat contains 
formaldehyde.
    (4) The testing laboratory shall periodically visit the plant to 
monitor quality control procedures to assure that all certified panels 
meet the standard.
    (5) To maintain its certification, plywood or particleboard must be 
tested by the air chamber test specified in Sec. 3280.406 whenever one 
of the following events occurs:
    (i) In the case of particleboard, the resin formulation is changed 
so that the formaldehyde-to-urea ratio is increased; or
    (ii) In the case of particleboard or plywood, the finishing or top 
coat is changed and the new finishing or top coat contains formaldehyde; 
or
    (iii) In the case of particleboard or plywood, the testing 
laboratory determines that an air chamber test is necessary to assure 
that panels comply with paragraph (a) of this section.
    (6) In the event that an air chamber test measures levels of 
formaldehyde from plywood or particleboard in excess of those permitted 
under paragraph (a) of this section, then the tested product's 
certification immediately lapses as of the date of production of the 
tested panels. No panel produced on the same date as the tested panels 
or on any day thereafter may be used or certified for use in 
manufactured homes.
    (i) Provided, however, that a new product certification may be 
obtained by testing randomly selected panels which were produced on any 
day following the date of production of the tested panels. If such 
panels pass the air chamber test specified in Sec. 3280.406, then the 
plywood or particleboard produced on that day and subsequent days may be 
used and certified for use in manufactured homes.
    (ii) Provided further, that plywood or particleboard produced on the 
same day as the tested panels, and panels produced on subsequent days, 
if not certified pursuant to paragraph (b)(4)(i) of this section, may be 
used in manufactured homes only under the following circumstances:
    (A) Each panel is treated with a scavenger, sealant, or other means 
of reducing formaldehyde emissions which does not adversely affect the 
structural quality of the product; and
    (B) Panels randomly selected from the treated panels are tested by 
and pass the air chamber test specified in Sec. 3280.406.
    (c) Panel identification. Each plywood and particleboard panel to be 
installed in manufactured homes which is bonded or coated with a resin 
system containing formaldehyde, other than an exclusively phenol-
formaldehyde resin system, shall be stamped or labeled so as to identify 
the product manufacturer, date of production and/or lot number, and the 
testing laboratory certifying compliance with this section.
    (d) Treatment after certification. If certified plywood or 
particleboard subsequently is treated with paint, varnish, or any other 
substance containing formaldehyde, then the certification is no longer 
valid. In such a case, each stamp or label placed on the panels pursuant 
to paragraph (c) of this section must be obliterated. In addition, the 
treated panels may be recertified and reidentified in accordance with 
paragraphs (b) and (c) of this section.

[49 FR 32011, Aug. 9, 1984]



Sec. 3280.309  Health Notice on formaldehyde emissions.

    (a) Each manufactured home shall have a Health Notice on 
formaldehyde emissions prominently displayed in a

[[Page 69]]

temporary manner in the kitchen (i.e., countertop or exposed cabinet 
face). The Notice shall read as follows:

                         Important Health Notice

    Some of the building materials used in this home emit formaldehyde. 
Eye, nose, and throat irritation, headache, nausea, and a variety of 
asthma-like symptoms, including shortness of breath, have been reported 
as a result of formaldehyde exposure. Elderly persons and young 
children, as well as anyone with a history of asthma, allergies, or lung 
problems, may be at greater risk. Research is continuing on the possible 
long-term effects of exposure to formaldehyde.
    Reduced ventilation resulting from energy efficiency standards may 
allow formaldehyde and other contaminants to accumulate in the indoor 
air. Additional ventilation to dilute the indoor air may be obtained 
from a passive or mechanical ventilation system offered by the 
manufacturer. Consult your dealer for information about the ventilation 
options offered with this home.
    High indoor temperatures and humidity raise formaldehyde levels. 
When a home is to be located in areas subject to extreme summer 
temperatures, an air-conditioning system can be used to control indoor 
temperature levels. Check the comfort cooling certificate to determine 
if this home has been equipped or designed for the installation of an 
air-conditioning system.
    If you have any questions regarding the health effects of 
formaldehyde, consult your doctor or local health department.

    (b) The Notice shall be legible and typed using letters at least \1/
4\ inch in size. The title shall be typed using letters at least \3/4\ 
inch in size.
    (c) The Notice shall not be removed by any party until the entire 
sales transaction has been completed (refer to part 3282--Manufactured 
Home Procedural and Enforcement Regulations for provisions regarding a 
sales transaction).
    (d) A copy of the Notice shall be included in the Consumer Manual 
(refer to part 3283--Manufactured Home Consumer Manual Requirements).

                            Subpart E_Testing



Sec. 3280.401  Structural load tests.

    Every structural assembly tested shall be capable of meeting the 
Proof Load Test or the Ultimate Load Test as follows:
    (a) Proof load tests. Every structural assembly tested must be 
capable of sustaining its dead load plus superimposed live loads equal 
to 1.75 times the required live loads for a period of 12 hours without 
failure. Tests must be conducted with loads applied and deflections 
recorded in \1/4\ design live load increments at 10-minute intervals 
until 1.25 times design live load plus dead load has been reached. 
Additional load shall then be applied continuously until 1.75 times 
design live load plus dead load has been reached. Assembly failure shall 
be considered as design live load deflection (or residual deflection 
measured 12 hours after live load removal) that is greater than the 
limits set in Sec. 3280.305(d), rupture, fracture, or excessive 
yielding. Design live load deflection criteria do not apply when the 
structural assembly being evaluated does not include structural framing 
members. An assembly to be tested shall be of the minimum quality of 
materials and workmanship of the production. Each test assembly, 
component, or subassembly shall be identified as to type and quality or 
grade of material. All assemblies, components, or subassemblies 
qualifying under this test shall be subject to a continuing 
qualification testing program acceptable to HUD.
    (b) Ultimate load tests. Ultimate load tests must be performed on a 
minimum of three assemblies or components to generally evaluate the 
structural design. Every structural assembly or component tested must be 
capable of sustaining its total dead load plus the design live load 
increased by a factor of safety of at least 2.5. A factor of safety 
greater than 2.5 shall be used when required by an applicable reference 
standard in Sec. 3280.304(b)(1). Tests shall be conducted with loads 
applied and deflections recorded in 1/4 design live load increments at 
10-minute intervals until 1.25 times design live load plus dead load has 
been reached. Additional loading shall then be applied continuously 
until failure occurs, or the total of the factor of safety times the 
design live load plus the dead load is reached. Assembly failure shall 
be considered as design live load deflection greater than

[[Page 70]]

the limits set in Sec. 3280.305(d), rupture, fracture, or excessive 
yielding. Design live load deflection criteria do not apply when the 
structural assembly being evaluated does not include structural framing 
members. Assemblies to be tested shall be representative of average 
quality or materials and workmanship of the production. Each test 
assembly, component, or subassembly shall be identified as to type and 
quality or grade of material. All assemblies, components, or 
subassemblies qualifying under this test shall be subject to a periodic 
qualification testing program acceptable to HUD.

Sec. 3280.402  Test procedures for roof trusses.

    (a) Roof load tests. This section provides the roof truss test 
procedure for vertical loading conditions. Where roof trusses act as 
support for other members, have eave or cornice projections, or support 
concentrated loads, roof trusses must also be tested for those 
conditions. These test procedures are required for new truss designs in 
all three wind zones and for existing truss designs used in Wind Zones 
II and III.
    (b) General. Trusses must be tested in a truss test fixture that 
replicates the design loads, and actual support points, and does not 
restrain horizontal movement. When tested singly or in groups of two or 
more trusses, trusses shall be mounted on supports and positioned as 
intended to be installed in the manufactured home in order to give the 
required clear span distance (L) and eave or cornice distance (Lo), if 
applicable, as specified in the design.
    (l) When trusses are tested singly, trusses shall be positioned in a 
test fixture, with supports properly located and the roof loads evenly 
applied. See Figure 3280.402(b)(1).
[GRAPHIC] [TIFF OMITTED] TR18JA13.001


[[Page 71]]


    (2) When tested in groups of two or more, the top chords are 
permitted to be sheathed with nominal 1/4-inch x 12-inch plywood strips. 
The plywood strips shall be at least long enough to cover the top chords 
of the trusses at the designated design truss spacing. Adjacent plywood 
strips shall be separated by at least 1/8-inch. The plywood strips shall 
be nailed with 4d nails or equivalent staples no closer than 8 inches on 
center along the top chord. The bottom chords of the adjacent trusses 
shall be permitted to be one of the following:
    (i) Unbraced; or
    (ii) Laterally braced together (not cross-braced) with 1-inch x 2-
inch stripping no closer than 24 inches on center, nailed with only one 
8d nail at each truss. See Figure 3280.402(b)(2).
[GRAPHIC] [TIFF OMITTED] TR18JA13.002

    (c) Measuring and loading methods. Deflections must be measured at 
the free end of an eave or cornice projection and at least at the truss 
mid-span and quarter points. Scissors or other unique truss 
configurations are to be measured at as many additional bottom chord 
panel points as necessary to obtain an accurate representation of the 
deflected shape of the truss so as to be able to locate and record the 
point(s) of maximum deflection. Deflections must be read and recorded 
relative to a fixed reference datum. Deflections must be read and 
recorded to the nearest 1/32-inch. Dead load must be applied to the top 
and bottom chord, and live load must be applied to the top chord through 
a suitable hydraulic, pneumatic, or mechanical system or weights to 
simulate design loads. Load unit weights for uniformly distributed top 
chord loads must be separated so that arch action does not occur and be 
spaced not more than 12 inches on center so as to simulate uniform 
loading. Bottom chord loading must be spaced as uniformly as practical. 
Truss gravity loads must be calculated based on the overall truss length 
(horizontal projection), including eave or cornice projections.
    (d) Testing procedures. Either the testing method in paragraph 
(d)(1) or (d)(2) of this section may be used, however, the testing 
method in paragraph (d)(3) of this section must be used, to test trusses 
to establish compliance with the provisions of these standards.
    (1) Proof load truss test procedure. At least three average quality/
consecutively tested trusses must pass all requirements of the test, for 
initial qualification of the truss design. All tests for initial 
qualification of the truss designs evaluated by this procedure must be 
certified by a Registered Engineer or Architect, or by a nationally 
recognized testing laboratory. An in-house quality control and follow-up 
testing

[[Page 72]]

program (see paragraphs (e) and (f) of this section) must be approved 
prior to entering production of any truss design evaluated by this 
procedure.
    (i) Dead load. Measure and record initial elevation of the truss or 
trusses in the test position at no load. Apply to the top and bottom 
chords of the truss dead loads that are representative of the actual 
weights of materials to be supported by the truss. However, the dead 
load may only be applied as indicated in paragraph (e)(4) of this 
section for ongoing follow-up testing. Dead loads to be applied to the 
truss test assembly are permitted to include only the weights of 
materials supported by the truss and not the weight of the truss itself. 
However, readings from load cells (when used) on which the test truss 
rests must reflect the sum of the applied load plus the weight of the 
truss. Apply dead loads and hold for 5 minutes. Measure and record the 
deflections.
    (ii) Live load. Maintaining the dead loads, apply live load to the 
top chord in approximate \1/4\ live load increments until dead load plus 
the live load is reached. Measure and record the deflections no sooner 
than one minute after each \1/4\ live load increment has been applied 
and 5 minutes after the full live load has been reached.
    (iii) Initial recovery phase. Remove the design live load but not 
the dead load. Measure and record the deflections 5 minutes after the 
total live load has been removed.
    (iv) Continue to load the truss to:
    (A) Dead load plus 2.0 times the design live load. Maintain this 
loading for 6 hours and inspect the truss for failure. Failure is 
rupture, fracture, or excessive yielding; or
    (B) Dead load plus 1.75 times the design live load. Maintain this 
loading for 12 hours and inspect the truss for failure. Failure is 
rupture, fracture, or excessive yielding.
    (v) Final recovery phase. Remove 2.0 times the design live load, but 
not the dead load or 1.75 times the design live load, but not the dead 
load. Measure and record deflections within 4 hours after removing 2.0 
times the design live load or 1.75 times the design live load.
    (vi) Acceptance criteria. The truss design is acceptable if all of 
the following conditions are met:
    (A) The maximum deflection between no load and dead load must be L/
480 or less for simply supported clear spans and Lo/180 or less for eave 
and cornice projections; and
    (B) The maximum deflection between dead load and design live load 
must be L/180 or less for simply supported clear spans and Lo/90 or less 
for eave and cornice projections; and
    (C) After the design live load is removed, and with the dead load 
still applied, the maximum recovery deflection must be L/360 or less for 
simply supported spans and Lo/180 or less for eave and cornice 
projections; and
    (D) The truss must maintain the overload condition for 6 hours 
without rupture or fracture, or excessive yielding; and
    (E) After 2.0 times the design live load has been removed, and with 
the dead load still applied, the maximum recovery deflection must be L/
180 or less for simply supported clear spans and Lo/90 or less for eave 
and cornice projections; and
    (F) As applicable, each truss design must also meet all requirements 
for uplift loads required by paragraph (d)(3) of this section. For Wind 
Zone I uplift load requirements, see paragraph (d)(3)(i) of this 
section. For Wind Zones II and III uplift load requirements, see 
paragraph (d)(3)(ii) of this section.
    (2) Ultimate load truss test procedure. (i) At least two average 
quality/consecutively tested trusses must pass all requirements of the 
test, for initial qualification of the truss design. All tests for 
initial qualification of the truss designs evaluated by this procedure 
must be certified by a Registered Engineer or Architect, or by a 
nationally recognized testing laboratory. An in-house quality control 
and follow-up testing program (see paragraph (e) and (f) of this 
section) must be approved prior to entering production of any truss 
design evaluated by this procedure.
    (ii) Dead load. Measure and record initial elevation of the truss or 
trusses in the test position at no load. Apply to the top and bottom 
chords of the

[[Page 73]]

truss dead loads that are representative of the actual weights of 
materials to be supported by the truss. However, the dead load may only 
be applied as indicated in paragraph (e)(4) of this section for ongoing 
follow-up testing. Dead loads to be applied to the truss test assembly 
shall be permitted to include only the weights of materials supported by 
the truss, and not the weight of the truss itself. However, readings 
from load cells (when used) on which the test truss rests must reflect 
the sum of the applied load plus the weight of the truss. Apply dead 
loads and hold for 5 minutes. Measure and record the deflections.
    (iii) Live load. Maintaining the dead loads, apply live load at a 
uniform rate to the top chord in approximate \1/4\ live load increments 
until the dead load plus the live load is reached. Measure and record 
the deflections no sooner than one minute after each \1/4\ live load 
increment has been applied and 5 minutes after the full live load has 
been reached.
    (iv) Initial recovery phase. Remove the design live load but not the 
dead load. Measure and record the deflections 5 minutes after the design 
live load has been removed.
    (v) Overload phase. After the recovery phase is completed, reapply 
the full live load to the truss assembly. Additional loading shall then 
be applied continuously until the dead load plus 2.5 times the design 
live load is reached. This overload condition must be maintained for at 
least 5 minutes.
    (vi) Final recovery phase. Remove 2.5 times the design live load but 
not the dead load. Measure and record deflections within 4 hours after 
2.5 times the design live load has been removed.
    (vii) Acceptance criteria. The truss design is acceptable if all of 
the following conditions are met:
    (A) The maximum deflection between no load and dead load must be L/
480 or less for simply supported clear spans and Lo/180 or less for eave 
and cornice projections; and
    (B) Dead load to design live load deflections shall be L/180 or less 
for simply supported clear spans and Lo/90 or less for eave and cornice 
projections; and
    (C) After the design live load is removed and with the dead load 
still applied, the maximum recovery deflection must be L/360 or less for 
simply supported spans and Lo/180 or less for eave and cornice 
projections; and
    (D) The truss shall maintain the overload condition for 5 minutes 
without rupture, fracture, or excessive yielding; and
    (E) After 2.5 times the design live load is removed, and with the 
dead load still applied, the truss must recover to at least L/180 for 
simply supported clear spans and Lo/90 for eave and cornice within 4 
hours after the total live load has been removed; and
    (F) As applicable, each truss design must also meet all requirements 
for uplift loads in Wind Zone I or Wind Zone II and III, as required by 
paragraph (d)(3) of this section. For Wind Zone I uplift load 
requirements, see paragraph (d)(3)(i) of this section. For Wind Zones II 
and III uplift load requirements, see paragraph (d)(3)(ii) of this 
section.
    (3) Uplift load tests. Each truss design must also pass all 
requirements of the uplift load test, as applicable, in paragraph 
(d)(3)(i) or (d)(3)(ii) and paragraphs (d)(3)(iii) and (d)(3)(iv) of 
this section.
    (i) Wind Zone I uplift load test. Where there are engineered 
connectors between the top chord and web members of the truss, such as 
metal connector plates or wood gussets or their equivalents, uplift 
testing in Wind Zone I is at the discretion of the Registered Engineer 
or Architect or nationally recognized testing laboratory certifying the 
truss design. When testing is deemed necessary by the Registered 
Engineer or Architect or nationally recognized testing laboratory 
certifying the truss design, a minimum of one average quality uplift 
load test is to be conducted for each such truss design and must pass 
all requirements of the test for initial qualification of the truss 
design. The net uplift load for trusses designed for use in Wind Zone I 
is 9 psf for the clear span of the truss and 22.5 psf for eave or 
cornice projections.
    (ii) Wind Zones II and III uplift loads test. This test is required 
for all trusses designed for use in Wind Zones II and

[[Page 74]]

III. A minimum of three average quality/consecutive uplift load tests 
are to be conducted for each truss design when tested in the inverted 
position and a minimum of two average quality/consecutive uplift load 
tests are to be conducted for trusses in the upright position. The 
trusses must pass all requirements of the test for initial qualification 
of the truss design. The uplift load for trusses designed to be used in 
Wind Zones II and III for the clear span or eave cornice projections is 
to be determined by subtracting the dead load applied to the truss from 
the uplift load provided in the Table of Design Wind Pressures in Sec. 
3280.305(c)(1)(ii)(B).
    (iii) Trusses designed for use in Wind Zone I, when tested (see 
paragraph (d)(3)(i) of this section), must be tested in either the 
inverted position to 2.5 times the net wind uplift load or in the 
upright position to 1.75 times the net wind uplift load. Trusses 
designed for use in Wind Zones II and III (see paragraph (d)(3)(ii) of 
this section) must be tested to 2.0 times the uplift load minus the dead 
load in the inverted position and to 1.75 times the uplift load minus 
the dead load in the upright position. See Figure 3280.402(b)(3).
    (iv) The following describes how to conduct the uplift test with the 
truss in the upright position. Similar procedures must be used if 
conducting the test in the inverted position.
    (A) Place the truss in the test fixture and position as it is 
intended to be installed in the manufactured home. See Figure 
3280.402(b)(3).
[GRAPHIC] [TIFF OMITTED] TR18JA13.003

    (B) Position the load measurement devices to register the wind 
uplift loads that will be applied to the top chord of the truss. The 
uplift loads shall be applied through tension devices not wider than one 
inch and spaced not greater than approximately 12 inches on center

[[Page 75]]

and shall be applied as uniform as possible, so as to simulate uniform 
loading. Gravity and wind uplift load tests may be performed on the same 
truss in this single setup mode. For the wind uplift test, it is 
permissible to stabilize the bottom chord of the truss in the test 
fixture to simulate ceiling materials or purlin supports. Measure and 
record the initial elevation of the bottom chord of the truss in the 
test position at the mid-span and quarter points of the truss, and at 
the free end of an eave or cornice projection greater than 12 inches. 
Scissors or other unique truss configurations are to be measured at as 
many additional bottom chord panel points as necessary to obtain an 
accurate representation of the deflected shape of the truss, so as to be 
able to locate and record the point(s) of maximum deflection. Eave or 
cornice projection loads are applied separately for eaves or cornice 
projections greater than 12 inches. For eave or cornice projections 
greater than 12 inches, the additional required load must be applied to 
the eave simultaneously with the main body load. For eave or cornice 
projections of 12 inches or less, add the additional required load to 
the main body load and apply it to the entire top chord.
    (C) Measure and record the deflection 5 minutes after the net uplift 
load has been applied. Design load deflection shall be L/180 or less for 
a simply supported clear span and Lo/90 or less for eave or cornice 
projections.
    (D) For trusses tested in the upright position, continue to load the 
truss to 1.75 times the net uplift load in paragraph (d)(3)(i) of this 
section for Wind Zone I and 1.75 times the uplift load in paragraph 
(d)(3)(ii) for Wind Zones II and III, and maintain the load for one 
minute. For trusses tested in the inverted position, continue to load 
the truss to 2.50 times the net uplift load in paragraph (d)(3)(i) for 
Wind Zone I and to 2.0 times the uplift load minus the dead load in 
paragraph (d)(3)(ii) for Wind Zones II and III, and maintain the full 
load for one minute. Regardless of the test position of the truss, 
upright or inverted, trusses must maintain the overload for the 
specified time period without rupture, fracture, or excessive yielding.
    (e) Follow-up testing. Follow-up testing procedures must include the 
following:
    (1) All trusses qualifying under these test procedures must be 
subject to a quality control and follow-up testing program.
    (i) Manufacturers of listed or labeled trusses must follow an in-
house quality control program with follow-up testing approved by a 
nationally recognized testing program as specified in paragraph (e)(3) 
of this section. The in-house quality control program must include, at a 
minimum, procedures for quality of materials including, but not limited 
to, grade(s) of materials, allowable splits, knots, and other applicable 
lumber qualities; workmanship including, but not limited to, plate 
placement and embedment tolerances; other manufacturing tolerances; 
description and calibration of test equipment; truss retesting criteria; 
and procedures in the event of noncomplying results.
    (ii) Those home manufacturers producing trusses for their own use, 
and which are not listed or labeled, must have an in-house quality 
control program (see paragraph (i) of this section) that includes 
follow-up testing, as specified in this section, and is approved by 
their Design Approval Primary Inspection Agency (DAPIA).
    (2) Truss designs that are qualified but not in production are not 
subject to follow-up testing until produced. When the truss design is 
brought into production, a follow-up test is to be performed if the 
truss design has been out of production for more than 6 months.
    (3) The frequency of truss manufacturer's quality control follow-up 
testing for trusses must be at least:
    (i) One test for the first 100 trusses produced, with a subsequent 
test for every 2,500 trusses for trusses qualified under the proof load 
truss test procedure or inverted uplift test procedure for trusses used 
in Wind Zones II and III or once every 6 months, whichever is more 
frequent, for every truss design produced; or
    (ii) One test for every 4,000 trusses produced for trusses qualified 
under the ultimate load truss test procedure or upright uplift test 
procedure for trusses used in Wind Zones II and III or

[[Page 76]]

once every 6 months, whichever is more frequent, for every truss design 
produced.
    (4) For follow-up testing only, the full dead load may be applied to 
the top chord of the truss, when the bottom chord dead load is 5 psf or 
less.

with a permeance no greater than 1 perm (dry cup method) installed on 
the living space side of the wall; or
    (2) Unventilated wall cavities must have an external covering and/or 
sheathing that forms the pressure envelope. The covering and/or 
sheathing must have a combined permeance of not less than 5.0 perms. In 
the absence of test data, combined permeance is permitted to be computed 
using the following formula: P total = (1/[(1/P1) + (1/
P2)]), where P1 and P2 are the

[[Page 80]]

permeance values of the exterior covering and sheathing in perms. Formed 
exterior siding applied in sections with joints not caulked or sealed, 
are not considered to restrict water vapor transmission; or
    (3) Wall cavities must be constructed so that ventilation is 
provided to dissipate any condensation occurring in these cavities; or
    (4) Homes manufactured to be sited in ``humid climates'' or ``fringe 
climates'' as shown on the Humid and Fringe Climate Map in this 
paragraph are permitted to have a vapor retarder specified in paragraph 
(b)(1) of this section installed on the exterior side of the wall 
insulation or be constructed with an external covering and sheathing 
with a combined permeance of not greater than 1.0 perms, provided the 
interior finish and interior wall panel materials have a combined 
permeance of not less than 5.0 perms. The following need not meet the 
minimum combined permeance rating of not less than 5.0 perms for 
interior finish or wall panel materials:
    (i) Kitchen back splash materials, less than 50 square feet in area 
installed around countertops, sinks, and ranges;
    (ii) Bathroom tub areas, shower compartments;
    (iii) Cabinetry and built-in furniture;

    (c) Liquid applied vapor retarders. Each liquid applied vapor 
retarder must be tested by a nationally recognized testing agency for 
use on the specific substrate to which it is applied. The test report 
must include the perm rating, as measured by ASTM E 96-95, Standard Test 
Methods for Water Vapor Transmission of Materials, and associated 
application rate for each specific substrate.
    (d) Attic or roof ventilation. (1) Attic and roof cavities shall be 
vented in accordance with one of the following:
    (i) A minimum free ventilation area of not less than 1/300 of the 
attic or roof cavity floor area. At least 50 percent of the required 
free ventilation area shall be provided by ventilators located in the 
upper portion of the space to be ventilated. At least 40 percent shall 
be provided by eave, soffit or low gable vents. The location and spacing 
of the vent openings and ventilators shall provide cross-ventilation to 
the entire attic or roof cavity space. A clear air passage space having 
a minimum height of 1 inch shall be provided between the top of the 
insulation and the roof sheathing or roof covering. Baffles or other 
means shall be provided where needed to insure the 1 inch height of the 
clear air passage space is maintained.
    (ii) A mechanical attic or roof ventilation system may be installed 
instead of providing the free ventilation area when the mechanical 
system provides a minimum air change rate of 0.02 cubic feet per minute 
(cfm) per sq. ft. of attic floor area. Intake and exhaust vents shall be 
located so as to provide air movement throughout space.
    (2) Single section manufactured homes constructed with metal roofs 
and having no sheathing or underlayment installed, are not required to 
be provided with attic or roof cavity ventilation provided that the air 
leakage paths from the living space to the roof cavity created by 
electrical outlets, electrical junctions, electrical cable penetrations, 
plumbing penetrations, flue pipe penetrations and exhaust vent 
penetrations are sealed.

[[Page 82]]

    (3) Parallel membrane roof section of a closed cell type 
construction are not required to be ventilated.
    (4) The vents provided for ventilating attics and roof cavities 
shall be designed to resist entry of rain and insects.

Sec. 3280.505  Air infiltration.

    (a) Envelope air infiltration. The opaque envelope shall be designed 
and constructed to limit air infiltration to the living area of the 
home. Any design, material, method or combination thereof which 
accomplishes this goal may be used. The goal of the infiltration control 
criteria is to reduce heat loss/heat gain due to infiltration as much as 
possible without impinging on health and comfort and within the limits 
of reasonable economics.
    (1) Envelope penetrations. Plumbing, mechanical and electrical 
penetrations of the pressure envelope not exempted by this part, and 
installations of window and door frames shall be constructed or treated 
to limit air infiltration. Penetrations of the pressure envelope made by 
electrical equipment, other than distribution panel boards and cable and 
conduit penetrations, are exempt from this requirement. Cable 
penetrations through outlet boxes are considered exempt.
    (2) Joints between major envelope elements. Joints not designed to 
limit air infiltration between wall-to-wall, wall-to-ceiling and wall-
to-floor connections shall be caulked or otherwise sealed. When walls 
are constructed to form a pressure envelope on the outside of the wall 
cavity, they are deemed to meet this requirement.



Sec. 3280.506  Heat loss/heat gain.

    The manufactured home heat loss/heat gain shall be determined by 
methods outlined in Sec. Sec. 3280.508 and 3280.509. The Uo 
(Coefficient of heat transmission) value zone for which the manufactured 
home is acceptable and the lowest outdoor temperature to which the 
installed heating equipment will maintain a temperature of 70 F shall be 
certified as specified in Sec. 3280.510 of this subpart. The Uo value 
zone shall be determined from the map in figure 506.

[[Page 83]]

    (a) Coefficient of heat transmission. The overall coefficient of 
heat transmission (Uo) of the manufactured home for the respective zones 
and an indoor design temperature of 70 F, including internal and 
external ducts, and excluding infiltration, ventilation and condensation 
control, shall not exceed

[[Page 84]]

the Btu/(hr.) (sq. ft.) (F) of the manufactured home envelope are as 
tabulated below:

                                            (F).
------------------------------------------------------------------------

    (b) To assure uniform heat transmission in manufactured homes, 
cavities in exterior walls, floors, and ceilings shall be provided with 
thermal insulation.
    (c) Manufactured homes designed for Uo Value Zone 3 shall be factory 
equipped with storm windows or insulating glass.

Sec. 3280.507  Comfort heat gain.

    Information necessary to calculate the home cooling load shall be 
provided as specified in this part.
    (a) Transmission heat gains. Homes complying with this section shall 
meet the minimum heat loss transmission coefficients specified in Sec. 
3280.506(a).



Sec. 3280.508  Heat loss, heat gain and cooling load calculations.

    (a) Information, values and data necessary for heat loss and heat 
gain determinations must be taken from the 1997 ASHRAE Handbook of 
Fundamentals, Inch-Pound Edition, chapters 22 through 27. The following 
portions of those chapters are not applicable:

23.1 Steel Frame Construction
23.2 Masonry Construction
23.3 Foundations and Floor Systems
23.15 Pipes
23.17 Tanks, Vessels, and Equipment
23.18 Refrigerated Rooms and Buildings
24.18 Mechanical and Industrial Systems
25.19 Commercial Building Envelope Leakage
27.9 Calculation of Heat Loss from Crawl Spaces

    (b) The calculation of the manufactured home's transmission heat 
loss coefficient (Uo) must be in accordance with the fundamental 
principles of the 1997 ASHRAE Handbook of Fundamentals, Inch-Pound 
Edition, and, at a minimum, must address all the heat loss or heat gain 
considerations in a manner consistent with the calculation procedures 
provided in the document, Overall U-values and Heating/Cooling Loads--
Manufactured Homes--February 1992-PNL 8006, HUD User No. 0005945.
    (c) Areas where the insulation does not fully cover a surface or is 
compressed shall be accounted for in the U-calculation (see Sec. 
3280.506). The effect of framing on the U-value must be included in the 
Uo calculation. Other low-R-value heat-flow paths (``thermal shorts'') 
shall be explicitly accounted for in the calculation of the transmission 
heat loss coefficient if in the aggregate all types of low-R-value paths 
amount to more than 1% of the total exterior surface area. Areas are 
considered low-R-value heat-flow paths if:
    (1) They separate conditioned and unconditioned space; and
    (2) They are not insulated to a level that is at least one-half the 
nominal insulation level of the surrounding building component.
    (d) High efficiency heating and cooling equipment credit. The 
calculated transmission heat loss coefficient (Uo) used for meeting the 
requirement in Sec. 3280.506(a) may be adjusted for heating and cooling 
equipment above that required by the National Appliance Energy 
Conservation Act of 1987 (NAECA) by applying the following formula:

Uo adjusted = Uo standardx[1+(0.6) (heating efficiency increase 
factor)+(cooling multiplier) (cooling efficiency increase factor)]

where:

Uo standard = Maximum Uo for Uo Zone required by Sec. 3280.506(a)
Uo adjusted = Maximum Uo standard adjusted for high efficiency HVAC 
          equipment
Heating efficiency increase factor = The increase factor in heating 
          equipment efficiency measured by the Annual Fuel Utilization 
          Efficiency (AFUE), or the Heating Seasonal Performance Factor 
          (HSPF) for heat pumps, above that required by NAECA (indicated 
          as ``NAECA'' in formula). The formula is heating efficiency 
          increase factor = AFUE (HSPF) home - AFUE (or HSPF) NAECA 
          divided by AFUE (HSPF) NAECA.
Cooling efficiency increase factor = the increase factor in the cooling 
          equipment

[[Page 85]]

          efficiency measured by the Seasonal Energy Efficiency Ratio 
          (SEER) above that required by NAECA.
The formula being cooling equipment=SEER home--SEER NAECA divided by 
          SEER NAECA.

    The cooling multiplier for the Uo Zone is from the following table:

------------------------------------------------------------------------
                 Uo zone                      Cooling multiplier (Cm)
------------------------------------------------------------------------
1........................................  0.60 (Florida only).
1........................................  0.20 (All other locations).
2........................................  0.07.
3........................................  0.03.
------------------------------------------------------------------------

    (e) U values for any glazing (e.g., windows, skylights, and the 
glazed portions of any door) must be based on tests using AAMA 1503.1-
1988, Voluntary Test Method for Thermal Transmittance and Condensation 
Resistance of Windows, Doors, and Glazed Wall Sections, or the National 
Fenestration Rating Council 100, 1997 Edition, Procedure for Determining 
Fenestration Product U-factors. In the absence of tests, manufacturers 
are to use the residential window U values contained in Chapter 29, 
Table 5 of the 1997 ASHRAE Handbook of Fundamentals, Inch-Pound Edition. 
In the event that the classification of the window type is 
indeterminate, the manufacturer must use the classification that gives 
the higher U value. Where a composite of materials from two different 
product types is used, the product is to be assigned the higher U value. 
For the purpose of calculating Uo values, storm windows are 
treated as an additional pane.
    (f) Annual energy used based compliance. As an alternative, homes 
may demonstrate compliance with the annual energy used implicit in the 
coefficient of heat transmission (Uo) requirement. The annual energy use 
determination must be based on generally accepted engineering practices. 
The general requirement is to demonstrate that the home seeking 
compliance approval has a projected annual energy use, including both 
heating and cooling, less than or equal to a similar ``base case'' home 
that meets the standard. The energy use for both homes must be 
calculated based on the same assumptions; including assuming the same 
dimensions for all boundaries between conditioned and unconditioned 
spaces, site characteristics, usage patterns and climate.

Sec. 3280.509  Criteria in absence of specific data.

    In the absence of specific data, for purposes of heat-loss/gain 
calculation, the following criteria shall be used:
    (a) Infiltration heat loss. In the absence of measured infiltration 
heat loss data, the following formula shall be used to calculate heat 
loss due to infiltration and intermittently operated fans exhausting to 
the outdoors. The perimeter calculation shall be based on the dimensions 
of the pressure envelope.

Infiltration Heat-Loss=0.7 (T) (ft. of perimeter), BTU/hr.

where: T=70 minus the heating system capacity certification temperature 
          stipulated in the Heating Certificate, in F.

    (b) Framing areas.

Wall.....................................  15 percent of wall area less
                                            windows and doors.
Floor and Ceiling........................  10 percent of the area.
 

    (c) Insulation compression. Insulation compressed to less than 
nominal thickness and loose-fill insulation in sloping cavities must 
have its nominal R-values reduced in compressed areas in accordance with 
the following table:

------------------------------------------------------------------------
 Note: To use this table, first compute the restricted insulation
  thickness as a fraction of the uncompressed (full) insulation
  thickness. Then look up the R-value remaining from the appropriate
  column (Non-uniform Restriction, Batt Non-uniform Restriction, Blown
  or Uniform Compression, Batt). Example: Assume a section of loose-fill
  ceiling insulation went from R-25 insulation at a height of 10 inches
  to a minimum height of 2 inches at the edge of the ceiling. The ratio
  of minimum to full thickness is 0.20 (2 divided by 10). Look up 0.20
  (20 percent), read across to column 3 (Non-uniform Restriction,
  Blown), and read 50 percent. Therefore, the R-value of the loose-fill
  insulation over the restricted area would be R-12.5 (50 percent of
  25).
(a) Non-uniform restriction is that which occurs between non-parallel
  planes, such as in the ceiling near the eaves.
(b) Uniform compression is compression between parallel planes, such as
  that which occurs in a wall.

    (d) Air supply ducts within floor cavity. Air supply ducts located 
within a floor cavity shall be assumed to be heating or cooling the 
floor cavity to living space temperatures unless the duct is 
structurally isolated by the framing system or thermally insulated from 
the rest of the floor cavity with a thermal insulation at least equal to 
R-4.
    (e) Air supply ducts within ceiling cavity. Where supply ducts are 
located in ceiling cavities, the influence of the duct on cavity 
temperatures shall be considered in calculating envelope heat loss or 
heat gain.
    (f) The supply duct loss (and/or heat gain where applicable--See 
Sec. 3280.511) shall be calculated using the actual duct surface area 
and the actual thickness of insulation between the duct and outside of 
the manufactured home. If there is an air space of at least \1/2\ inch 
between the duct and the insulation, heat loss/gain need not be 
calculated if the cavity in which the duct is located

[[Page 87]]

is assumed to be at living space temperature. The average temperature 
inside the supply duct, including ducts installed outside the 
manufactured home, shall be assumed to be 130 F for purposes of 
calculation of heat loss and 60 F for heat gain.
    (g) Return air cavities. Cavities used as return air plenums shall 
be considered to be at living space temperature.

[deg]F temperature inside the home without storm sash or insulating 
glass for Zones 1 and 2, and with storm sash or insulating glass for 
Zone 3 and complying with Sec. 3280.508 and Sec. 3280.509.
    (c) Operating economy certification temperature. The temperature to 
be specified for operating economy and energy conservation shall be 20 
[deg]F or 30% of the design temperature difference, whichever is 
greater, added to the temperature specified as the heating system 
capacity certification temperature without storm windows or insulating 
glass in Zones 1 and 2 and with storm windows or insulating glass in 
Zone 3. Design temperature difference is 70[deg] minus the heating 
system capacity certification temperature in degrees Fahrenheit.

methods for evidence or indication of leakage:
    (1) Water test. Before plumbing fixtures are connected, all of the 
openings into the piping shall be plugged and the entire piping system 
subjected to a static water test for 15 minutes by filling it with water 
to the top of the highest vent opening. There shall be no evidence of 
leakage.
    (2) Air test. After all fixtures have been installed, the traps 
filled with water, and the remaining openings securely plugged, the 
entire system shall be subjected to a 2-inch (manometer) water column 
air pressure test. If the system loses pressure, leaks may be located 
with smoke pumped into the system, or with soap suds spread on the 
exterior of the piping (Bubble test).
    (3) Flood level test. The manufactured home shall be in a level 
position, all fixtures shall be connected, and the entire system shall 
be filled with water to the rim of the water closet bowl. (Tub and 
shower drains shall be plugged). After all trapped air has been 
released, the test shall be sustained for not less than 15 minutes 
without evidence of leaks. Then the system shall be unplugged and 
emptied. The waste piping above the level of the water closet bowl shall 
then be tested and show no indication of leakage when the high fixtures 
are filled with water and emptied simultaneously to obtain the maximum 
possible flow in the drain piping.
    (c) Fixture test. The plumbing fixtures and connections shall be 
subjected to a flow test by filling them with water and checking for 
leaks and retarded flow while they are being emptied.
    (d) Shower compartments. Shower compartments and receptors shall be 
tested for leaks prior to being covered by finish material. Each pan 
shall be filled with water to the top of the dam for not less than 15 
minutes without evidence of leakage.

manufactured home and shall be based on a 3-wire, 120/240 volt supply 
with 120 volt loads balanced between the two legs of the 3-wire system. 
The total load for determining power supply by this method is the 
summation of:
    (1) Lighting and small appliance load as calculated below:
    (i) Lighting volt-amperes: Length time width of manufactured home 
(outside dimensions exclusive of coupler) times 3 volt-amperes per 
square foot; e.g. Length x width x 3=lighting volt-amperes.
    (ii) Small appliance volt-amperes: Number of circuits time 1,500 
volt-amperes for each 20-ampere appliance receptacle circuit (see 
definition of ``Appliance Portable'' with Note): e.g. Number of circuits 
x 1,500=small appliance volt-amperes.
    (iii) Total volts-amperes: Lighting volts-amperes plus small 
appliance=total volt-amperes.
    (iv) First 3,000 total volts-amperes at 100 percent plus remainder 
at 35 percent=watts to be divided by 240 volts to obtain current 
(amperes) per leg.
    (2) Nameplate amperes for motors and heater loads (exhaust fans, air 
conditioners, electric, gas, or oil heating). Omit smaller of air 
conditioning and heating except include blower motor if used as air 
conditioner evaporator

[[Page 134]]

motor. When an air conditioner is not installed and a 40-ampere power 
supply cord is provided, allow 15 amperes per leg for air conditioning.
    (3) 25 percent of current of largest motor in paragraph (a)(2) of 
this section.
    (4) Total of nameplate amperes for: Disposal, dishwasher, water 
heater, clothes dryer, wall-mounted oven, cooking units. Where number of 
these appliances exceeds three, use 75 percent of total.
    (5) Derive amperes for free-standing range (as distinguished from 
separate ovens and cooking units) by dividing values below by 240 volts.

[40 FR 58752, Dec. 18, 1975. Redesignated at 44 FR 20679, Apr. 6, 1979, 
as amended at 47 FR 28093, June 29, 1982]



Sec. 3280.903  General requirements for designing the structure to
withstand transportation shock and vibration.

    (a) The cumulative effect of highway transportation shock and 
vibration upon a manufactured home structure may result in incremental 
degradation of its designed performance in terms of providing a safe, 
healthy and durable dwelling. Therefore, the manufactured home shall be 
designed, in terms of its structural, plumbing, mechanical and 
electrical systems, to fully withstand such transportation forces during 
its intended life. (See Sec. Sec. 3280.303(c) and 3280.305(a)).
    (b) Particular attention shall be given to maintaining watertight 
integrity and conserving energy by assuring that structural components 
in the roof and walls (and their interfaces with vents, windows, doors, 
etc.) are capable of resisting highway shock and vibration forces during 
primary and subsequent secondary transportation moves.
    (c) In place of an engineering analysis, either of the following may 
be accepted:
    (1) Documented technical data of suitable highway tests which were 
conducted to simulate transportation loads and conditions; or
    (2) Acceptable documented evidence of actual transportation 
experience which meets the intent of this subpart.



system.

    (a) General. The entire system (frame, drawbar and coupling 
mechanism, running gear assembly, and lights) shall be designed and 
constructed as an integrated, balanced and durable unit

[[Page 137]]

which is safe and suitable for its specified use during the intended 
life of the manufactured home. In operation, the transportation system 
(supporting the manufactured home structure and its contents) shall 
effectively respond to the control of the braking, while traveling at 
applicable towing vehicle in terms of tracking and highway speeds and in 
normal highway traffic conditions.
    Note: While the majority of manufactured homes utilize a fabricated 
steel frame assembly, upon which the manufactured home structure is 
constructed, it is not the intent of this standard to limit innovation. 
Therefore, other concepts, such as integrating the frame function into 
the manufactured home structure, are acceptable provided that such 
design meets the intent and requirements of this part).
    (b) Specific requirements--(1) Drawbar. The drawbar shall be 
constructed of sufficient strength, rigidity and durability to safely 
withstand those dynamic forces experienced during highway 
transportation. It shall be securely fastened to the manufactured home 
frame by either a continuous weld or by bolting.
    (2) Coupling mechanism. The coupling mechanism (which is usually of 
the socket type) shall be securely fastened to the drawbar in such a 
manner as to assure safe and effective transfer of the maximum loads, 
including dynamic loads, between the manufactured home structure and the 
hitch-assembly of the towing vehicle. The coupling shall be equipped 
with a manually operated mechanism so adapted as to prevent 
disengagement of the unit while in operation. The coupling shall be so 
designed that it can be disconnected regardless of the angle of the 
manufactured home to the towing vehicle. With the manufactured home 
parked on level ground, the center of the socket of the coupler shall 
not be less than 20 inches nor more than 26 inches from ground level.
    (3) Chassis. The chassis, in conjunction with the manufactured home 
structure, shall be designed and constructed to effectively sustain the 
designed loads consisting of the dead load plus a minimum of 3 pounds 
per square foot floor load, (example: free-standing range, refrigerator, 
and loose furniture) and the superimposed dynamic load resulting from 
highway movement but shall not be required to exceed twice the dead 
load. The integrated design shall be capable of insuring rigidity and 
structural integrity of the complete manufactured home structure and to 
insure against deformation of structural or finish members during the 
intended life of the home.
    (4) Running gear assembly. (i) The running gear assembly, as part of 
the chassis, shall be designed to perform, as a balanced system, in 
order to effectively sustain the designed loads set forth in Sec. 
3280.904(b)(3) and to provide for durable dependable safe mobility of 
the manufactured home. It shall be designed to accept shock and 
vibration, both from the highway and the towing vehicle and effectively 
dampen these forces so as to protect the manufactured home structure 
from damage and fatigue. Its components shall be designed to facilitate 
routine maintenance, inspection and replacement.
    (ii) Location of the running gear assembly shall be determined by 
documented engineering analysis, taking into account the gross weight 
(including all contents), total length of the manufactured home, the 
necessary coupling hitch weight, span distance, and turning radius. The 
coupling weight shall be not less than 12 percent nor more than 25 
percent of the gross weight.
    (5) Spring assemblies. Spring assemblies (springs, hangers, 
shackles, bushings and mounting bolts) shall be capable of withstanding 
all the design loads as outlined in Sec. 3280.904(b)(3) without 
exceeding maximum allowable stresses for design spring assembly life as 
recommended by the spring assembly manufacturer. The capacity of the 
spring system shall assure, that under maximum operating load 
conditions, sufficient clearance shall be maintained between the tire 
and manufactured home frame or structure to permit unimpeded wheel 
movement and for changing tires.
    (6) Axles. Axles, and their connecting hardware, shall be capable of 
withstanding all of the design loads outlined in Sec. 3280.904(b)(3) 
without exceeding maximum allowable stresses for design axle life as 
recommended by the axle manufacturer. The number of

[[Page 138]]

axles required to provide a safe tow and good ride characteristics shall 
be determined and documented by engineering analysis. Those alternatives 
listed in Sec. 3280.903(c) may be accepted in place of such an 
analysis.
    (7) Hubs and bearings. Hubs and bearings shall meet the requirements 
of Sec. 3280.904(b)(3) and good engineering practice. Both of these 
components shall be accessible for inspection, routine maintenance and 
replacement of parts.
    (8) Tires, wheels and rims. Tires, wheels and rims shall meet the 
requirements of Sec. 3280.904(b)(3). Tires shall be selected for 
anticipated usage.
    (9) Brake assemblies. (i) The number, type, size and design of brake 
assemblies required to assist the towing vehicle in providing effective 
control and stopping of the manufactured home shall be determined and 
documented by engineering analysis. Those alternatives listed in Sec. 
3280.903(c) may be accepted in place of such an analysis.
    (ii) Brakes on the towing vehicle and the manufactured home shall be 
capable of assuring that the maximum stopping distance from an initial 
velocity of 20 miles per hour does not exceed 40 feet (U.S. Department 
of Transportation Regulations).
    (10) Lights and associated wiring. Highway safety electrical lights 
and associated wiring shall conform to applicable Federal requirements 
in terms of location and performance. The manufacturer shall have the 
option of meeting this requirement by utilizing a temporary light/wiring 
harness provided by the manufactured home transportation carrier.

Sec. 3282.11  Preemption and reciprocity.

    (a) No State manufactured home standard regarding manufactured home 
construction and safety which covers aspects of the manufactured home 
governed by the Federal standards shall be established or continue in 
effect with respect to manufactured homes subject to the Federal 
standards and these regulations unless it is identical to the Federal 
standards.
    (b) No State may require, as a condition of entry into or sale in 
the State, a manufactured home certified (by the application of the 
label required by Sec. 3282.362(c)(2)(i)) as in conformance with the 
Federal standards to be subject to State inspection to determine 
compliance with any standard covering any aspect of the manufactured 
home covered by the Federal standards. Nor may any State require that a 
State label be placed on the manufactured home certifying conformance to 
the Federal standard or an identical standard. Certain actions that 
States are permitted to take are set out in Sec. 3282.303.
    (c) States may participate in the enforcement of the Federal 
standards enforcement program under these regulations either as SAAs or 
PIAs or both. These regulations establish the exclusive system for 
enforcement of the Federal standards. No State may establish or keep in 
effect through a building code enforcement system or otherwise, 
procedures or requirements which constitute systems for enforcement of 
the Federal standards or of identical State standards which are outside 
the system established in these regulations or which go beyond this 
system to require remedial actions which are not required by the Act and 
these regulations. A State may establish or continue in force consumer 
protections, such as warranty or warranty performance requirements, 
which respond to individual consumer complaints and so do not constitute 
systems of enforcement of the Federal standards, regardless of whether 
the State qualifies as an SAA or PIA.
    (d) No State or locality may establish or enforce any rule or 
regulation or take any action that stands as an obstacle to the 
accomplishment and execution of the full purposes and objectives of 
Congress. The test of whether a State rule or action is valid or must 
give way is whether the State rule can be enforced or the action taken 
without impairing the Federal superintendence of the manufactured home 
industry as established by the Act.

[[Page 146]]

    (c) When a manufacturer makes a certification provided for under 
paragraph (b) of this section, the certification shall state as follows:

    The manufacturer of this structure, Name --------------------; 
Address --------------------; (location where structure was 
manufactured).

    Certifies that this structure (Ser. No. --------) is not a 
manufactured home subject to the provisions of the National Manufactured 
Housing Construction and Safety Standards Act and is--
    (1) designed only for erection or installation on a site-built 
permanent foundation,
    (2) not designed to be moved once so erected or installed,
    (3) designed and manufactured to comply with -------------- (Here 
state which code included in paragraph (b)(3) of this section has been 
followed), and
    (4) to the manufacturer's knowledge is not intended to be used other 
than on a site-built permanent foundation.

    (d) This certification shall be affixed in a permanent manner near 
the electrical panel, on the inside of a kitchen cabinet door, or in any 
other readily accessible and visible location.
    (e) As part of this certification, the manufacturer shall identify 
each certified structure by a permanent serial number placed on the 
structure during the first stage of production. If the manufacturer also 
manufactures manufactured homes that are certified under Sec. Sec. 
3282.205 and 3282.362(c), the series of serial numbers for structures 
certified under this section shall be distinguishable on the structures 
and in the manufacturer's records from the series of serial numbers for 
the manufactured homes that are certified under Sec. Sec. 3282.205 and 
3282.362(c).
    (1) If a manufacturer wishes to certify a structure as a 
manufactured home under Sec. Sec. 3282.205 and 3282.362(c) after having 
applied a serial number identifying it as exempted under this section, 
the manufacturer may do so only with the written consent of the 
Production Inspection Primary Inspection Agency (IPIA) after thorough 
inspection of the structure by the IPIA at at least one stage of 
production and such removal or equipment, components, or materials as 
the IPIA may require to perform inspections to assure that the structure 
conforms to the Federal manufactured home standards. The manufacturer 
shall remove the original serial number and add the serial number 
required by Sec. 3280.6.
    (2) A manufacturer may not certify a structure under this section 
after having applied the manufactured home serial number under Sec. 
3280.6.
    (f) All certifications made under this section are subject to 
investigation by the Secretary to determine their accuracy. If a 
certification is false or inaccurate, the certification for purposes of 
this section is invalid and the structures that have been or may be the 
subject of the certification are not excluded from the coverage of the 
Act, the Federal Manufactured Home Construction and Safety Standards, or 
these Regulations.
    (1) If the Secretary has information that a certification may be 
false or inaccurate, the manufacturer will be given written notice of 
the nature of this information by certified mail and the procedure of 
this subparagraph will be followed.
    (i) The manufacturer must investigate this matter and report its 
findings in writing as to the validity of this information to the 
Secretary within 15 days from the receipt of the Secretary's notice.
    (ii) If a written report is received within the time prescribed in 
paragraph (f)(1)(i) of this section, the Secretary will review this 
report before determining whether a certification is false or 
inaccurate. If a report is not received within 15 days from the receipt 
of the Secretary's notice, the Secretary will make the determination on 
the basis of the information presented.
    (iii) If the Secretary determines that a certification is false or 
inaccurate, the manufacturer will be given written notice and the 
reasons for this determination by certified mail.
    (2) The Secretary may seek civil and criminal penalties provided for 
in section 611 of the Act, 42 U.S.C. 5410, if the party in question in 
the exercise of due care has reason to know that such certification is 
false or misleading as to any material fact.

Sec. 3282.13  Voluntary certification.

    (a) The purpose of this section is to provide a procedure for 
voluntary certification of non-conforming manufactured homes as required 
by 42 U.S.C. 5402(6) as amended by section 308(d)(B) of the Housing and 
Community Development Act of 1980.
    (b) Structures which meet all of the requirements of a manufactured 
home as set out in Sec. 3282.7(u), except the size requirements, shall 
be manufactured homes if the manufacturer files with the Secretary a 
certification in the following form:

    [Name of manufacturer and address where structures are to be 
manufactured] certifies that it intends to manufacture structures that 
meet all of the requirements of manufactured homes set forth at 42 
U.S.C. 5402(6) except the size requirements. Such structures are to be 
treated as manufactured homes for the purposes of the National 
Manufactured Housing Construction and Safety Standards Act of 1974 and 
the regulations promulgated pursuant thereto. Such structures will be 
built in conformance with the Standards. [Name of manufacturer] further 
certifies that if, at any time it manufactures structures which are not 
manufactured homes, it will identify each such structure by a permanent 
serial number placed on the structure during the first stage of 
production and that the series of serial numbers for such structures 
shall be distinguishable on the structures and in its records from the 
series of serial numbers used for manufactured homes.

    (c) Whenever a manufacturer which has filed a certification pursuant 
to Sec. 3282.13(b) produces structures which are not manufactured 
homes, it must identify each such structure by placing a permanent 
serial number on the structure during the first stage of production. The 
series of serial numbers placed on these structures shall be 
distinguishable on the structure and in the manufacturer's records from 
the series of serial numbers used for manufactured homes.
    (d) A manufacturer may certify a structure as a manufactured home 
after having applied a serial number identifying it as a structure which 
is not a manufactured home. To do so, the manufacturer must secure the 
written consent of the IPIA. This consent may only be given after a 
DAPIA has approved the manufacturer's design and quality assistance 
manual in accordance with Sec. 3282.361, and after the IPIA has 
thoroughly inspected the structure in at least one stage of production 
and after such removal of equipment, components or materials as the IPIA 
may require to assure that the structure conforms to the standards. 
After certification as a manufactured home has been approved, the 
manufacturer shall remove the original serial number and add the serial 
number required by Sec. 3280.6.
    (e) Once a manufacturer has certified under Sec. 3282.13(b) that it 
intends to build structures which are manufactured homes in all respects 
except size, the manufacturer must then, with respect to those 
structures, comply with all of the requirements of the Act and its 
regulations. The structures may not thereafter be exempted under any 
other section of these regulations.

[47 FR 28093, June 29, 1982]



Sec. 3282.14  Alternative construction of manufactured homes.

    (a) Policy. In order to promote the purposes of the Act, the 
Department will permit the sale or lease of one or more manufactured 
homes not in compliance with the Standards under circumstances wherein 
no affirmative action is needed to protect the public interest. The 
Department encourages innovation and the use of new technology in 
manufactured homes. Accordingly, HUD will permit manufacturers to 
utilize new designs or techniques not in compliance with the Standards 
in cases:
    (1) Where a manufacturer proposes to utilize construction that would 
be prohibited by the Standards;
    (2) Where such construction would provide performance that is 
equivalent to or superior to that required by the Standards; and
    (3) Where (i) compliance with the Standards would be unreasonable 
because of the circumstances of the particular case, or (ii) the 
alternative construction would be for purposes of research, testing or 
development of new techniques or designs. If a request for alternative 
construction is submitted and the facts are consistent with these 
principles, the Secretary may issue a

[[Page 148]]

letter under paragraph (c) of this section stating that no action will 
be taken under the Act based upon specific failures to conform to the 
Standards or these regulations, provided that certain conditions are 
met. The issuance of a letter under paragraph (c) of this section will 
not affect any right that any purchaser may have under the Act or other 
applicable law and will not preclude any further agency action that may 
become necessary.
    (b) Request for alternative construction. A manufacturer may submit 
a request for alternative construction of a manufactured home. The 
request should be sent to the U.S. Department of Housing and Urban 
Development, Manufactured Housing Standards Division, 451 Seventh 
Street, SW., Washington, DC 20410. The request must include:
    (1) A copy of the manufactured design or plan for each nonconforming 
model which a manufacturer plans to build;
    (2) An explanation of the manner in which the design fails to 
conform with the Standards, including a list of the specific standards 
involved;
    (3) An explanation of how the design will result in homes that 
provide the same level of performance, quality, durability and safety as 
would be provided under the Standards;
    (4) A copy of data adequate to support the request, including 
applicable test data, engineering calculations or certifications from 
nationally recognized laboratories;
    (5) An estimate of the maximum number of manufactured home units 
affected and the location, if known, to which the units will be shipped;
    (6) An indication of the period of time during which the 
manufacturer proposes to engage in the manufacture, sale or lease of the 
nonconforming homes;
    (7) A copy of the proposed notice to be provided to home purchasers;
    (8) A list of the names and addresses of any retailers that would be 
selling the nonconforming homes; and
    (9) A letter from the manufacturer's DAPIA indicating that the 
design(s) to which any nonconforming homes would be built meet the 
Standards in all other respects.
    (c) Issuance of the letter by the Secretary--(1) Contents of the 
letter. If the Secretary issues a letter in response to a request for 
alternative construction, the letter shall include the specific 
standards affected, an explanation of the proposed activity or design, 
an explanation of how the request is consistent with the objectives of 
the Act, and any conditions that the manufacturer must meet.
    (2) Letter sent to IPIA, DAPIA and SAA. The Secretary shall forward 
a copy of the letter to the manufacturer's IPIA and DAPIA along with a 
letter authorizing the DAPIA to approve plans containing the alternative 
construction, and authorizing the IPIA to permit use of the alternative 
construction, provided that the conditions set forth in the letter are 
met. The Secretary shall also forward a copy of the letter to the SAAs 
in the State of manufacture and the State(s) in which the homes are to 
be located, if known.
    (3) Alternative construction in additional models. In cases where 
the Secretary grants a letter under this paragraph that is not model-
specific, the Secretary may permit the manufacturer to include the 
alternative construction in additional models. In such cases, the DAPIA 
shall notify the Department of additional models that incorporate the 
alternative construction.
    (d) Revocation. The Secretary may revoke or amend a letter issued 
under paragraph (c) of this section at any time. Such revocation or 
amendment will be prospective only. Where manufacturers have requested 
alternative construction for research, testing or development such 
alternative construction may not achieve the anticipated results. 
Therefore, the Secretary may require a manufacturer to bring those homes 
into compliance with the standards if, after the alternative 
construction has been in use for a period of time specified by the 
Secretary, these homes are not, in the Secretary's judgment, providing 
the levels of safety, quality and durability which would have been 
provided had the homes been built in compliance with the Standards.
    (e) Notice to prospective purchasers. Manufacturers receiving 
letters under

[[Page 149]]

paragraph (c) of this section shall provide notice to prospective 
purchasers that the home does not conform to the Standards. Such notice 
shall be delivered to each prospective purchase before he or she enters 
into an agreement to purchase the home. The notice shall be in the 
following form or in such other form as may be approved by the 
Secretary:

                          Notice to Purchasers

    The Department of Housing and Urban Development has issued a letter 
to (Name of Manufacturer) concerning the homes in (location if known). 
As designed, the homes do not meet Federal Manufactured Home 
Construction and Safety Standards regarding (brief statement of 
manufacturer's nonconformance).
    HUD has evaluated the alternative construction and believes that it 
provides an equivalent level of quality, durability and safety to that 
provided by the Standards.
    For further information about the specific Federal Standards

   Subpart D_Informal and Formal Presentations of Views, Hearings and 
                             Investigations



Sec. 3282.151  Applicability and scope.

    (a) This subpart sets out procedures to be followed when an 
opportunity to present views provided for in the Act is requested by an 
appropriate party. Section 3282.152 provides for two types of procedures 
that may be followed, one informal and nonadversary, and one more formal 
and adversary. Section 3282.152 also sets out criteria to govern which 
type of procedure will be followed in particular cases.
    (b) The procedures of Sec. 3282.152 also apply to:
    (1) Proceedings held by the Secretary whenever the suspension or 
disqualification of a primary inspection agency, which has been granted 
final approval, is recommended under Sec. 3282.356 of these 
regulations, and
    (2) Resolution of disputes where an SAA or manufacturer disagrees 
with a determination of a DAPIA under Sec. 3282.361 that a manufactured 
home design does or does not conform to the standards or that a quality 
assurance manual is or is not adequate with a decision by an IPIA to red 
tag or not to red tag or to provide or not to provide a certification 
label for a manufactured home under Sec. 3282.362 when the IPIA 
believes that the manufactured home does or does not conform to the 
standards.
    (c) The procedures set out in Sec. 3282.152 shall also be followed 
whenever State Administrative Agencies hold Formal or Informal 
Presentations of Views under Sec. 3282.309.
    (d) To the extent that these regulations provide for Formal or 
Informal Presentations of Views for parties that would otherwise qualify 
for hearings under 2 CFR part 2424, the procedures of 2 CFR part 2424 
shall not be available and shall not apply.

[41 FR 19852, May 13, 1976, as amended at 51 FR 34467, Sept. 29, 1986; 
61 FR 10442, Mar. 13, 1996; 72 FR 73497, Dec. 27, 2007]



Sec. 3282.152  Procedures to present views and evidence.

    (a) Policy. All Formal and Informal Presentations of Views under 
this subpart shall be public, unless, for good cause, the Secretary 
determines it is in the public interest that a particular proceeding 
should be closed. If the Secretary determines that a proceeding should 
be closed, the Secretary shall state and make publicly available the 
basis for that determination.
    (b) Request. Upon receipt of a request to present views and evidence 
under the Act, the Secretary shall determine whether the proceeding will 
be a Formal or an Informal Presentation of Views, and shall issue a 
notice under paragraph (c) of this section.
    (c) Notice. When the Secretary decides to conduct a Formal or an 
Informal Presentation of Views under this section, the Secretary shall 
provide notice as follows:
    (1) Except where the need for swift resolution of the question 
involved prohibits it, notice of a proceeding hereunder shall be 
published in the Federal Register at least 10 days prior to the date of 
the proceeding. In any case, notice shall be provided to interested 
persons to the maximum extent practicable. Direct notice shall be sent 
by certified mail to the parties involved in the hearing.
    (2) The notice, whether published or mailed, shall include a 
statement of the time, place and nature of the proceeding; reference to 
the authority under which the proceeding will be held; a statement of 
the subject matter of the proceeding, the parties and issues involved; 
and a statement of the

[[Page 152]]

manner in which interested persons shall be afforded the opportunity to 
participate in the hearing.
    (3) The notice shall designate the official who shall be the 
presiding officer for the proceedings and to whom all inquiries should 
be directed concerning such proceedings.
    (4) The notice shall state whether the proceeding shall be held in 
accordance with the provisions of paragraph (f)--(Informal Presentation 
of Views) or paragraph (g)--(Formal Presentation of Views) of this 
section, except that when the Secretary makes the determinations 
provided for in sections 623 (d) and (f) of the Act, the requirements of 
paragraph (g) of this section shall apply. In determining whether the 
requirements of paragraph (f) or those of paragraph (g) of this section 
shall apply the Secretary shall consider the following:
    (i) The necessity for expeditious action;
    (ii) The risk of injury to affected members of the public;
    (iii) The economic consequences of the decisions to be rendered; and
    (iv) Such other factors as the Secretary determines are appropriate.
    (d) Department representative. If the Department is to be 
represented by Counsel, such representation shall be by a Department 
hearing attorney designated by the General Counsel.
    (e) Reporting and transcription. Oral proceedings shall be 
stenographically or mechanically reported and transcribed under the 
supervision of the presiding officer, unless the presiding officer and 
the parties otherwise agree, in which case a summary approved by the 
presiding officer shall be kept. The original transcript or summary 
shall be a part of the record and the sole official transcript, or 
summary. A copy of the transcript or summary shall be available to any 
person at a fee established by the Secretary, which fee the Secretary 
may waive in the public interest. Any information contained in the 
transcript or summary which would be exempt from required disclosure 
under Sec. 3282.54 of these regulations may be protected from 
disclosure if appropriate under that section upon a request for such 
protection under Sec. 3282.54(c).
    (f) Informal presentation of views. (1) An Informal Presentation of 
Views may be written or oral, and may include an opportunity for an oral 
presentation, whether requested or not, whenever the Secretary concludes 
that an oral presentation would be in the public interest, and so states 
in the notice. A presiding officer shall preside over all oral 
presentations held under this subsection. The purpose of any such 
presentation shall be to gather information to allow fully informed 
decision making. Informal Presentations of Views shall not be adversary 
proceedings. Oral presentations shall be conducted in an informal but 
orderly manner. The presiding officer shall have the duty and authority 
to conduct a fair proceeding, to take all necessary action to avoid 
delay, and to maintain order. In the absence of extraordinary 
circumstances, the presiding officer at an oral Informal Presentation of 
Views shall not require that testimony be given under an oath or 
affirmation, and shall not permit either cross-examination of witnesses 
by other witnesses or their representatives, or the presentation of 
rebuttal testimony by persons who have already testified. The rules of 
evidence prevailing in courts of law or equity shall not control the 
conduct of oral Informal Presentations of Views.
    (2) Within 10 days after an Informal Presentation of Views, the 
presiding officer shall refer to the Secretary all documentary evidence 
submitted, the transcript, if any, a summary of the issues involved and 
information presented in the Informal Presentation of Views and the 
presiding official's recommendations, with the rationale therefor. The 
presiding officer shall make any appropriate statements concerning the 
apparent veracity of witnesses or the validity of factual assertions 
which may be within the competence of the presiding officer. The 
Secretary shall issue a Final Determination concerning the matters at 
issue within 30 days of receipt of the presiding officer's summary. The 
Final Determination shall include:
    (i) A statement of findings, with specific references to principal 
supporting items of evidence in the record and conclusions, as well as 
the reasons or bases therefor, upon all of the material

[[Page 153]]

issues of fact, law, or discretion as presented on the record, and
    (ii) An appropriate order. Notice of the Final Determination shall 
be given in writing and transmitted by certified mail, return receipt 
requested, to all participants in the presentation of views. The Final 
Determination shall be conclusive, with respect to persons whose 
interests were represented.
    (g) Formal presentation of views. (1) A Formal Presentation of Views 
is an adversary proceeding and includes an opportunity for the oral 
presentation of evidence. All witnesses shall testify under oath or 
affirmation, which shall be administered by the presiding officer. 
Participants shall have the right to present such oral or documentary 
evidence and to conduct such cross-examination as the presiding officer 
determines is required for a full and true disclosure of facts. The 
presiding officer shall receive relevant and material evidence, rule 
upon offers of proof and exclude all irrelevant, immaterial or unduly 
repetitious evidence. However, the technicalities of the rules of 
evidence prevailing in courts of law or equity shall not control the 
conduct of a Formal Presentation of Views. The presiding officer shall 
take all necessary action to regulate the course of the Formal 
Presentation of Views to avoid delay and to maintain order. The 
presiding officer may exclude the attorney or witness from further 
participation in the particular Formal Presentation of Views and may 
render a decision adverse to the interests of the excluded party in his 
absence.
    (2) Decision. The presiding officer shall make and file an initial 
written decision on the matter in question. The decision shall be filed 
within 10 days after completion of the oral presentation. The decision 
shall include:
    (i) A statement of findings of fact, with specific references to 
principal supporting items of evidence in the record and conclusions, as 
well as the reasons or bases therefor, upon all of the material issues 
of law or discretion presented on the record, and
    (ii) An appropriate order.

The presiding officer's decision shall be final and shall constitute the 
Final Determination of the Secretary unless reversed or modified within 
30 days by the Secretary. Notice of the Final Determination shall be 
given in writing, and transmitted by registered or certified mail, 
return receipt requested, to all participants in the proceeding. The 
Final Determination shall be conclusive with respect to persons whose 
interests were represented.

Sec. 3282.153  Public participation in formal or informal presentation
of views.

    (a) Any interested persons may participate, in writing, in any 
Formal or Informal Presentation of Views held under the provisions of 
paragraph (f) or (g) of Sec. 3282.152. The presiding officer shall, to 
the extent practicable, consider any such written materials.
    (b) Any interested person may participate in the oral portion of any 
Formal or Informal Presentation of Views held under paragraphs (f) and 
(g) of Sec. 3282.152 unless the presiding officer determines that 
participation should be limited or barred so as not unduly to prejudice 
the rights of the parties directly involved or unnecessarily to delay 
the proceedings.

Sec. 3282.155  Investigations.

    The procedures for investigations and investigational proceedings 
are set forth in part 3800 of this chapter.

[61 FR 10442, Mar. 13, 1996]



Sec. 3282.156  Petitions for investigations.

    (a) Any person may petition the Secretary in writing to open an 
investigation into whether noncompliances, defects, serious defects, or 
imminent safety hazards exist in manufactured homes. A petition shall 
include the reasons that the petitioner believes warrant an 
investigation, and it shall state any steps which have previously been 
taken to remedy the situation. The petition shall include all 
information known to the petitioner concerning the identity of 
manufactured homes which may be affected and where those manufactured 
homes were manufactured. The Secretary shall respond to petitions 
concerning alleged imminent safety hazards and serious defects within 60 
days and to petitions alleging the existence of defects or 
noncompliances within 120 days.
    (b) Any person may petition the Secretary in writing to undertake an 
investigation for the purpose of determining whether a primary 
inspection agency should be disqualified. The petition shall set out all 
facts and information on which the petition is based and a detailed 
statement of why such information justifies disqualification. The 
Secretary shall consider such petitions when making determinations on 
final acceptance and continued acceptance. The Secretary shall respond 
to such petition within 120 days.



    Subpart E_Manufacturer Inspection and Certification Requirements



Sec. 3282.201  Scope and purpose.

    (a) This subpart sets out requirements which must be met by 
manufacturers of manufactured homes for sale to purchasers in the United 
States with respect to certification of manufactured home designs, 
inspection of designs, quality assurance programs, and manufactured home 
production, and certification of manufactured homes. Other than 
references and a general description of responsibilities, this subpart 
does not set out requirements with respect to remedial actions or 
reports which must be taken or filed under the Act and these 
regulations.
    (b) The purpose of this subpart is to require manufacturers to 
participate in a system of design approvals and inspections which serve 
to assist them in assuring that manufactured homes which they 
manufacture will conform to Federal standards. Such approvals and 
inspections provide significant protection to the public by decreasing 
the number of manufactured homes with possible defects in them, and 
provide protection to manufacturers by reducing the number of instances 
in which costly remedial actions must be undertaken after manufactured 
homes are sold.



Sec. 3282.202  Primary inspection agency contracts.

    Each manufacturer shall enter into a contract or other agreement 
with as many Design Inspection Primary Inspection Agencies (DAPIAs) as 
it wishes and with enough Production Inspection Primary Inspection 
Agencies (IPIAs) to provide IPIA services for each manufacturing plant 
as set out in this subpart and in subpart H of this part. In return for 
the services provided by the DAPIAs and IPIAs, each manufacturer shall 
pay such reasonable fees as are agreed upon between the manufacturer and 
the primary inspection agency or, in the case of a State acting as an 
exclusive IPIA under Sec. 3282.3 such fees as may be established by the 
State.



Sec. 3282.203  DAPIA services.

    (a) Each manufacturer shall have each manufactured home design and 
each quality assurance manual which it intends to follow approved by a 
DAPIA under Sec. 3282.361. The manufacturer is free to choose which 
DAPIA will evaluate and approve its designs and quality assurance 
materials manufacturer may obtain design and quality assurance manual 
approval from a single DAPIA regardless of the number of plants in which 
the design and quality assurance manual will be followed. A manufacturer 
may also obtain approval

[[Page 155]]

for the same design and quality assurance manual from more than one 
DAPIA. The choice of which DAPIA or DAPIAs to employ is left to the 
manufacturer.
    (b) The manufacturer shall submit to the DAPIA such information as 
the DAPIA may require in order to carry out design approvals. This 
information shall, except where the manufacturer demonstrates to the 
DAPIA that it is not necessary, include the following:
    (1) Construction drawings and/or specifications showing structural 
details and layouts of frames, floors, walls and roofs, and chassis; 
material specifications, framing details, door locations, etc., for each 
floor plan proposed to be manufactured,
    (2) Structural analysis and calculations, test data and/or other 
accepted engineering practices used by the manufacturer to validate the 
design,
    (3) Complete heat loss calculations for each significant variation 
of home design,
    (4) Floor plans showing room arrangement and sizes, window sizes, 
emergency exists and locations, locations of smoke alarms, fixed 
appliance range hoods, and other standards related aspects of the 
manufactured home that can be shown on the floor plans,
    (5) Diagrams of the fuel supply system, potable water system and 
drain, waste and vent systems. The diagrams shall specify the types of 
materials used, types of fittings and methods of installing required 
safety equipment,
    (6) Wiring diagrams, including circuit allocation of electrical load 
and branch circuit calculations, a table of the branch circuit 
protection provided, the type of wiring used, and wiring methods,
    (7) Details showing the design of air supply and return systems,
    (8) Details of chassis construction, components, connections and 
running gear including rating capacities of tires,
    (9) A list of fixed and portable appliances furnished with the 
manufactured home, including type of appliance, rating of appliance, and 
applicable minimum and maximum performance ratings and/or energy 
requirements,
    (10) Detailed manufacturer installation instructions including 
specifications and procedures for the erection and hook-up of the home 
at its permanent location, and
    (11) Reports of all tests that were run to validate the conformance 
of the design to the standards.
    (c) The manufacturer shall submit to the DAPIA such information as 
the DAPIA may require in order to carry out quality assurance manual 
approvals. At a minimum, this information shall include the quality 
assurance manual for which approval is sought. That manual shall include 
the manufacturer's quality assurance program, an organizational chart 
showing the accountability, by position, of the manufacturer's quality 
control personnel, a description of production tests and test equipment 
required for compliance with the standards, a station-by-station 
description of the manufacturing process, a list of quality control 
inspections required by the manufacturer at each station, and 
identification by title of each person who will be held accountable for 
each quality control inspection.
    (d) Manufacturers may be required to furnish supplementary 
information to the DAPIA if the design information or the quality 
assurance manual is not complete or if any information is not in 
accordance with accepted engineering practice.
    (e) When a manufacturer wishes to make a change in an approved 
design or quality assurance manual, the manufacturer shall obtain the 
approval of the DAPIA which approved the design or manual prior to 
production for sale. The procedures for obtaining such approval are set 
out in Sec. 3282.361.
    (f) The information to be submitted to a DAPIA under Sec. 3282.203 
(b) and (c) may be prepared by the manufacturer's staff or outside 
consultants, including other DAPIAs. However, a DAPIA may not perform 
design or quality assurance manual approvals for any manufacturer whose 
design or manual has been created or prepared in whole or in part by 
members of the DAPIA's organization or of any affiliated organization.

[[Page 156]]

    (g) Each manufacturer shall maintain a copy of the drawings, 
specifications, and sketches from each approved design received from a 
DAPIA under Sec. 3282.361(b)(4) in each plant in which manufactured 
homes are being produced to the design. Each manufacturer shall also 
maintain in each manufacturing plant a copy of the approved quality 
assurance manual received from a DAPIA under Sec. 3282.361(c)(3) that 
is being followed in the plant. These materials shall be kept current 
and shall be readily accessible for use by the Secretary or other 
parties acting under these regulations.

[41 FR 19852, May 13, 1976, as amended at 67 FR 12818, Mar. 19, 2002]



Sec. 3282.204  IPIA services.

    (a) Each manufacturer shall obtain the services of an IPIA as set 
out in Sec. 3282.362 for each manufacturing plant operated by the 
manufacturer.
    (b) The manufacturer shall make available to the IPIA operating in 
each of its plants a copy of the drawings and specifications from the 
DAPIA approved design and the quality assurance manual for that plant, 
and the IPIA shall perform an initial factory inspection as set out in 
Sec. 3282.362(b). If the IPIA issues a deviation report after the 
initial factory inspection, the manufacturer shall make any corrections 
or adjustments which are necessary to conform with the DAPIA approved 
designs and manuals. After the corrections required by the deviation 
report are completed to the satisfaction of the IPIA, the IPIA shall 
issue the certification report as described in Sec. 3282.362(b)(2). In 
certain instances a DAPIA may provide the certification report. (See 
Sec. 3282.362) The manufacturer shall maintain a current copy of each 
certification report in the plant to which the certification report 
relates.
    (c) After the certification report has been signed by the IPIA, the 
manufacturer shall obtain labels from the IPIA and shall affix them to 
completed manufactured homes as set out in Sec. 3282.362(c)(2). During 
the initial factory certification, the IPIA may apply labels to 
manufactured homes which it knows to be in compliance with the standards 
if it is performing complete inspections of all phases of production of 
each manufactured home and the manufacturer authorizes it to apply 
labels.
    (d) During the course of production the manufacturer shall maintain 
a complete set of approved drawings, specifications, and approved design 
changes for the use of the IPIA's inspector and always available to that 
inspector when in the manufacturing plant.
    (e) If during the course of production, an IPIA finds a failure to 
conform to a standard exists in a manufactured home under production, 
the manufacturer must correct the failure to conform in any manufactured 
home still in the factory and held by distributors or retailers and 
shall carry out remedial actions under Sec. 3282.416(a) with respect to 
any other manufactured homes which may contain the same failure to 
conform.

[41 FR 19852, May 13, 1976, as amended at 78 FR 60199, Oct. 1, 2013]



Sec. 3282.205  Certification requirements.

    (a) Every manufacturer shall make a record of the serial number of 
each manufactured home produced, and a duly authorized representative of 
the manufacturer shall certify that each manufactured home has been 
constructed in accordance with the Federal standards. The manufacturer 
shall furnish a copy of that certification to the IPIA for the purpose 
of determining which manufactured homes are subject to the notification 
and correction requirements of subpart I of this part.
    (b) Every manufacturer of manufactured homes shall certify on the 
data plate as set out in Sec. 3280.5 of chapter XX of 24 CFR and Sec. 
3282.362(c)(3) that the manufactured home is designed to comply with the 
Federal manufactured home construction and safety standards in force at 
the time of manufacture in addition to providing other information 
required to be completed on the data plate.
    (c) Every manufacturer of manufactured homes shall furnish to the 
retailer or distributor of each of its manufactured homes a 
certification that such manufactured home, to the best of

[[Page 157]]

the manufacturer's knowledge and belief, conforms to all applicable 
Federal construction and safety standards. This certification shall be 
in the form of the label provided by the IPIA under Sec. 
3282.362(c)(2). The label shall be affixed only at the end of the last 
stage of production of the manufactured home.
    (d) The manufacturer shall apply a label required or allowed by the 
regulations in this part only to a manufactured home that the 
manufacturer knows by its inspections to be in compliance with the 
standards.

Sec. 3282.206  Disagreement with IPIA or DAPIA.

    Whenever a manufacturer disagrees with a finding by a DAPIA or an 
IPIA acting in accordance with subpart H of this part, the manufacturer 
may request a Formal or Informal Presentation of Views as provided in 
Sec. 3282.152. The manufacturer shall not, however, produce 
manufactured homes pursuant to designs which have not been approved by a 
DAPIA or produce manufactured homes which the relevant IPIA believes not 
to conform to the standards unless and until:
    (a) The Secretary determines that the manufacturer is correct in 
believing the design of the manufactured home conforms to the standards; 
or
    (b) Extraordinary interim relief is granted under Sec. 3282.154; or
    (c) The DAPIA or IPIA otherwise resolves the disagreement.

61 FR 10860, Mar. 15, 1996]



Sec. 3282.207  Manufactured home consumer manual requirements.

    (a) The manufacturer shall provide a consumer manual with each 
manufactured home that enters the first stage of production on or after 
July 31, 1977, pursuant to section 617 of the National Manufactured 
Housing Construction and Safety Standards Act, 42 U.S.C. 5416.
    (b) The manufacturer shall provide the consumer manual by placing a 
manual in each such manufactured home before the manufactured home 
leaves the manufacturing plant. The manual shall be placed in a 
conspicuous location in a manner likely to assure that it is not removed 
until the purchaser removes it.
    (c) If a manufacturer is informed that a purchaser did not receive a 
consumer manual, the manufacturer shall provide the appropriate manual 
to the purchaser within 30 days of being so informed.
    (d) No retailer or distributor may interfere with the distribution 
of the consumer manual. When necessary, the retailer or distributor 
shall take any appropriate steps to assure that the purchaser receives a 
consumer manual from the manufacturer.
    (e) Dispute resolution information. (1) The manufacturer must 
include the following language under a heading of ``Dispute Resolution 
Process'' in the consumer manual:

    Many states have a consumer assistance or dispute resolution program 
that homeowners may use to resolve problems with manufacturers, 
retailers, or installers concerning defects in their manufactured homes 
that render part of the home unfit for its intended use. Such state 
programs may include a process to resolve a dispute among a 
manufacturer, a retailer, and an installer about who will correct the 
defect. In states where there is not a dispute resolution program that 
meets the federal requirements, the HUD Manufactured Home Dispute 
Resolution Program will operate. These are ``HUD-administered states.'' 
The HUD Manufactured Home Dispute Resolution Program is not for cosmetic 
or minor problems in the home. You may contact the HUD Manufactured 
Housing Program Office at (202) 708-6423 or (800) 927-2891, or visit the 
HUD website at www.hud.gov to determine whether your state has a state 
program or whether you should use the HUD Manufactured Home Dispute 
Resolution Program. Contact information for state programs is also 
available on the HUD website. If your state has a state program, please 
contact the state for information about the program, how it operates, 
and what steps to take to request dispute resolution. When there is no 
state dispute resolution program, a homeowner may use the HUD 
Manufactured Home Dispute Resolution Program to resolve disputes among 
the manufacturer, retailer, and installer about responsibility for the 
correction or repair of defects in the manufactured home that were 
reported during the 1-year period starting on the date of installation. 
Even after the 1-year period, manufacturers have

[[Page 158]]

continuing responsibility to review certain problems that affect the 
intended use of the manufactured home or its parts, but for which 
correction may no longer be required under federal law.

    (2) The manufacturer must include the following language under a 
heading of ``Additional Information `` HUD Manufactured Home Dispute 
Resolution Program'' in the consumer manual:

    The steps and information outlined below apply only to the HUD 
Manufactured Home Dispute Resolution Program that operates in HUD-
administered states, as described under the heading ``Dispute Resolution 
Information'' in this manual. Under the HUD Manufactured Home Dispute 
Resolution Program, homeowners must report defects to the manufacturer, 
retailer, installer, a State Administrative Agency, or HUD within 1 year 
after the date of the first installation. Homeowners are encouraged to 
report defects in writing, including, but not limited to, email, written 
letter, certified mail, or fax, but they may also make a report by 
telephone. To demonstrate that the report was made within 1 year after 
the date of installation, homeowners should report defects in a manner 
that will create a dated record of the report: for example, by certified 
mail, by fax, or by email. When making a report by telephone, homeowners 
are encouraged to make a note of the phone call, including names of 
conversants, date, and time. No particular format is required to submit 
a report of an alleged defect, but any such report should at a minimum 
include a description of the alleged defect, the name of the homeowner, 
and the address of the home.
    Homeowners are encouraged to send reports of an alleged defect first 
to the manufacturer, retailer, or installer of the manufactured home, or 
a State Administrative Agency. Reports of alleged defects may also be 
sent to HUD at: HUD, Office of Regulatory Affairs and Manufactured 
Housing, Attn: Dispute Resolution, 451 Seventh Street, SW., Washington, 
DC 20410-8000; faxed to (202) 708-4213; e-mailed to [email protected], or 
reported telephonically at (202) 708-6423 or (800) 927-2891.
    If, after taking the steps outlined above, the homeowner does not 
receive a satisfactory response from the manufacturer, retailer, or 
installer, the homeowner may file a dispute resolution request with the 
dispute resolution provider in writing, or by making a request by phone. 
No particular format is required to make a request for dispute 
resolution, but the request should generally include the following 
information:
    (1) The name, address, and contact information of the homeowner;
    (2) The name and contact information of the manufacturer, retailer, 
and installer of the manufactured home;
    (3) The date or dates the report of the alleged defect was made;
    (4) Identification of the entities or persons to whom each report of 
the alleged defect was made and the method that was used to make the 
report;
    (5) The date of installation of the manufactured home affected by 
the alleged defect; and
    (6) A description of the alleged defect.
    Information about the dispute resolution provider and how to make a 
request for dispute resolution is available at http://www.hud.gov or by 
contacting the Office of Manufactured Housing Programs at (202) 708-6423 
or (800) 927-2891.
    A screening agent will review the request and, as appropriate, 
forward the request to the manufacturer, retailer, installer, and 
mediator. The mediator will mediate the dispute and attempt to 
facilitate a settlement. The parties to a settlement include, as 
applicable, the manufacturer, retailer, and installer. If the parties 
are unable to reach a settlement that results in correction or repair of 
the alleged defect, any party or the homeowner may request nonbinding 
arbitration. Should any party refuse to participate, the arbitration 
shall proceed without that party's input. Once the arbitrator makes a 
non-binding recommendation, the arbitrator will forward it to the 
parties and HUD. HUD will have the option of adopting, modifying, or 
rejecting the recommendation when issuing an order requiring the 
responsible party or parties to make any corrections or repairs in the 
home. At any time before HUD issues a final order, the parties may 
submit an offer of settlement to HUD that may, at HUD's discretion, be 
incorporated into the order.
    In circumstances where the parties agree that one or more of them, 
and not the homeowner, is responsible for the alleged defect, the 
parties will have the opportunity to resolve the dispute outside of the 
HUD Mediation and Arbitration process by using the Alternative Process. 
Homeowners will maintain the right to be informed in writing of the 
outcome when the Alternative Process is used, within 5 days of the 
outcome. At any time after 30 days of the Alternative Process 
notification, any participant or the homeowner may invoke the HUD 
Manufactured Home Dispute Resolution Program and proceed to mediation.
    The HUD Manufactured Home Dispute Resolution Program is not a 
warranty program and does not replace the manufacturer's or any other 
warranty program.

    (f) If a consumer manual or a change or revision to a manual does 
not substantially comply with the guidelines

[[Page 159]]

issued by HUD, the manufacturer shall cease distribution of the consumer 
manual and shall provide a corrected manual for each manufactured home 
for which the inadequate or incorrect manual or revision was provided. A 
manual substantially complies with the guidelines if it includes the 
language in paragraph (e) of this section and presents current material 
on each of the subjects covered in the guidelines in sufficient detail 
to inform consumers about the operation, maintenance, and repair of 
manufactured homes. An updated copy of guidelines published in the 
Federal Register on March 15, 1996, can be obtained by contacting the 
Office of Manufactured Housing and Regulatory Functions, Department of 
Housing and Urban Development, 451 Seventh Street, SW., Washington, DC, 
20410; the Information Center, Department of Housing and Urban 
Development, Room 1202, 451 Seventh Street, SW., Washington, DC, 20410; 
or any HUD Area or State Office.

Sec. 3282.208  Remedial actions--general description.

    (a) Notification. A manufacturer may be required to provide formal 
notice to manufactured home owners and retailers, as set out in subpart 
I of this part, if the manufacturer, the Secretary, or a State 
Administrative Agency determines under that subpart that an imminent 
safety hazard, serious defect, defect, or noncompliance exists or may 
exist in a manufactured home produced by that manufacturer.
    (b) Correction. A manufacturer may be required to correct imminent 
safety hazards and serious defects which the manufacturer or the 
Secretary determines under subpart I exist in manufactured homes 
produced by the manufacturer. This correction would be carried out in 
addition to the sending of formal notice as described in paragraph (a) 
of this section.
    (c) Cooperation. The manufacturer shall be responsible for working 
with the DAPIA, IPIA, any SAA, the Secretary, and the Secretary's agent 
as necessary in the course of carrying out investigations and remedial 
actions under subpart I.
    (d) Avoidance of formalities. The provisions for notification and 
required correction outlined in paragraphs (a) and (b) of this section 
and described more fully in subpart I may be waived or avoided in 
certain circumstances under that subpart.



Sec. 3282.209  Report requirements.

    The manufacturer shall submit reports to the PIAs, SAAs, and the 
Secretary as required by subpart L of these regulations.



Sec. 3282.210  Payment of monitoring fee.

    (a) Each manufacturer shall pay the monitoring fee established under 
Sec. Sec. 3282.307 and 3282.454 for each transportable section of each 
manufactured housing unit that it manufactures under the Federal 
standards.
    (b) The monitoring fee shall be paid in the form of a check made 
payable to the Secretary or the Secretary's agent. The manufacturer 
shall give to the IPIA (or to any other person or agency designated in 
writing by the Secretary) the required check in the amount of the number 
of labels, as required by Sec. 3282.365, multiplied by the amount of 
the fee per transportable section of each manufactured housing unit.

[50 FR 28398, July 12, 1985]



Sec. 3282.211  Record of purchasers.

    (a) Information requirements for purchasers. (1) Every manufacturer 
of manufactured homes shall, for each manufactured home manufactured 
under the Federal standards, provide with the manufactured home a 
booklet containing at least 3 detachable cards as described in paragraph 
(a)(2) of this section. On the front of the booklet, in bold faced type, 
shall be printed the following language:

    ``Keep this booklet with your manufactured home. Title VI of the 
Housing and Community Development Act of 1974 provides you with 
protection against certain construction and safety hazards in your 
manufactured home. To help assure your protection, the manufacturer of 
your manufactured home needs the information which these cards, when 
completed and mailed, will supply. If you bought your home from a 
retailer, please be sure that your retailer has completed and mailed a 
card for you. If you acquired your home from someone who is not

[[Page 160]]

a retailer, you should promptly fill out and send a card to the 
manufacturer. It is important that you keep this booklet and give it to 
any person who buys the manufactured home from you.''

    (2) The detachable cards shall contain blanks for the following 
information:
    (i) Name and address of the retailer or other person selling the 
manufactured home to the purchaser;
    (ii) Name and complete mailing address of the manufactured home 
purchaser;
    (iii) Address where the manufactured home will be located, if not 
the same as item (a)(2)(ii) of this section.
    (iv) Date of sale to the purchaser;
    (v) Month, day and year of manufacture;
    (vi) Identification number of the manufactured home;
    (vii) Model and/or type designation of the manufactured home as 
provided by the manufacturer; and
    (viii) A designation of the zones for which the manufactured home is 
equipped, as set forth in Sec. 3280.305 in this title.

Additionally, the cards shall have the name and address of the 
manufacturer printed clearly on the reverse side and shall contain 
adequate postage or business reply privileges to ensure return to the 
manufacturer. The manufacturer shall have the responsibility for filing 
in the blanks on the cards for paragraphs (a)(2) (v), (vi), (vii), and 
(viii) of this section.
    (3) The manufacturer shall maintain all cards received so that the 
manufacturer has a readily accessible record of the current purchaser or 
owner and the current address of all manufactured homes manufactured by 
it for which a card has been received.



           Subpart F_Retailer and Distributor Responsibilities



Sec. 3282.251  Scope and purpose.

    (a) This subpart sets out the responsibilities which shall be met by 
distributors and retailers with respect to manufactured homes 
manufactured after the effective date of the standards for sale to 
purchasers in the United States. It prohibits the sale, lease, or offer 
for sale or lease of manufactured homes known by the distributor or 
retailer not to be in conformance with the standards, and it includes 
responsibilities for maintaining certain records and assisting in the 
gathering of certain information.
    (b) The purpose of this subpart is to inform distributors and 
retailers when they may sell manufactured homes, when they are 
prohibited from selling manufactured homes, and what they may do in 
order to prepare a manufactured home for sale if it is not in 
conformance with the standards.
    (c) For purposes of this part, any manufacturer or distributor who 
sells, leases, or offers for sale or lease a manufactured home to a 
purchaser shall be a retailer for purposes of that transaction.



Sec. 3282.252  Prohibition of sale.

    (a) No distributor or retailer shall make use of any means of 
transportation affecting interstate or foreign commerce or the mails to 
sell, lease, or offer for sale or lease in the United States any 
manufactured home manufactured on or after the effective date of an 
applicable standard unless:
    (1) There is affixed to the manufactured home a label certifying 
that the manufactured home conforms to applicable standards as required 
by Sec. 3282.205(c), and
    (2) The distributor or retailer, acting as a reasonable distributor 
or retailer, does not know that the manufactured home does not conform 
to any applicable standards.
    (b) This prohibition applies to any affected manufactured homes 
until the completion of the entire sales transaction. A sales 
transaction with a purchaser is considered completed when all the goods 
and services that the retailer agreed to provide at the time the 
contract was entered into have been provided. Completion of a retail 
sale will be at the time the retailer completes set-up of the 
manufactured home if the retailer has agreed to provide the set-up, or 
at the time the retailer delivers the home to a transporter, if the 
retailer has not agreed to transport or set up the manufactured home, or 
to the site if the retailer has not agreed to provide set-up.

[[Page 161]]

    (c) This prohibition of sale does not apply to manufactured homes 
which are placed in production prior to the effective date of the 
standards, and it does not apply to ``used'' manufactured homes which 
are being sold or offered for sale after the first purchase in good 
faith for purposes other than the resale.



Sec. 3282.253  Removal of prohibition of sale.

    (a) If a distributor or retailer has a manufactured home in its 
possession or a manufactured home with respect to a sales transaction 
has not yet been completed, and a distributor or retailer knows as a 
result of notification by the manufacturer or otherwise that the 
manufactured home contains a failure to conform or imminent safety 
hazard, the distributor or retailer may seek the remedies available 
under Sec. 3282.415.
    (b) When, in accordance with Sec. 3282.415, a manufacturer corrects 
a failure to conform to the applicable standard or an imminent safety 
hazard, the distributor or retailer, acting as a reasonable distributor 
or retailer, may accept the remedies provided by the manufacturer as 
having corrected the failure to conform or imminent safety hazard. The 
distributor or retailer, therefore, may sell, lease, or offer for sale 
or lease any manufactured home so corrected by the manufacturer.
    (c) When a distributor or retailer is authorized by a manufacturer 
to correct a failure to conform to the applicable standard or an 
imminent safety hazard and completes the correction in accordance with 
the manufacturer's instructions, the distributor or retailer may sell, 
or lease or offer for sale or lease the manufactured home in question, 
provided that the distributor or retailer, acting as a reasonable 
distributor or retailer knows that the manufactured home conforms to the 
standards. A distributor or retailer and a manufacturer, at the 
manufacturer's option, may agree in advance that the distributor or 
retailer is authorized to make such corrections as the manufacturer 
believes are within the expertise of the dealer.
    (d) If the corrections made under paragraphs (b) and (c) of this 
section do not bring the manufactured home into conformance or correct 
the imminent safety hazard, the provisions of Sec. 3282.415 will 
continue in effect prior to completion of the sales transaction.

[41 FR 19852, May 13, 1976, as amended at 78 FR 60199, Oct. 1, 2013]



Sec. 3282.254  Distributor and retailer alterations.

    (a) If a distributor or retailer alters a manufactured home in such 
a way as to create an imminent safety hazard or to create a condition 
which causes a failure to conform with applicable Federal standards, the 
manufactured home affected may not be sold, leased, or offered for sale 
or lease.
    (b) After correction by the distributor or retailer of the failure 
to conform or imminent safety hazard, the corrected manufactured home 
may be sold, leased, or offered for sale or lease.
    (c) Distributors and retailers shall maintain complete records of 
all alterations made under paragraphs (a) and (b) of this section.



Sec. 3282.255  Completion of information card.

    (a) Whenever a distributor or retailer sells a manufactured home 
subject to the standards to a purchaser, the distributor or retailer 
shall fill out the card with information provided by the purchaser and 
shall send the card to the manufacturer. (See Sec. 3282.211.)
    (b) Whenever a distributor or retailer sells a manufactured home to 
an owner which was originally manufactured under the standards, the 
distributor or retailer shall similarly use one of the detachable cards 
which was originally provided with the manufactured home. If such a card 
is no longer available, the distributor or retailer shall obtain the 
information which the card would require and send it to the manufacturer 
of the manufactured home in an appropriate format.



Sec. 3282.256  Distributor or retailer complaint handling.

    (a) When a distributor or retailer believes that a manufactured home 
in its possession which it has not yet sold to a purchaser contains an 
imminent safety hazard, serious defect, defect, or

[[Page 162]]

noncompliance, the distributor or retailer shall refer the matter to the 
manufacturer for remedial action under Sec. 3282.415. If the 
distributor or retailer is not satisfied with the action taken by the 
manufacturer, it may refer the matter to the SAA in the state in which 
the manufactured home is located, or to the Secretary if there is no 
such SAA.
    (b) Where a distributor or retailer receives a consumer complaint or 
other information concerning a manufactured home sold by the distributor 
or retailer, indicating the possible existence of an imminent safety 
hazard, serious defect, defect, or noncompliance in the manufactured 
home, the distributor or retailer shall refer the matter to the 
manufacturer.

    (e) Exclusive IPIA status. (1) A State that wishes to act as an 
exclusive IPIA

[[Page 164]]

under Sec. 3282.352 shall so indicate in its State Plan and shall 
include in the information provided under paragraph (b)(11) of this 
section the fee schedule for the State's activities as an IPIA and the 
relationship between the proposed fees and the other information 
provided under paragraph (b)(11) of this section. If the Secretary 
determines that the fees to be charged by a State acting as an IPIA are 
unreasonable, the Secretary shall not grant the State status as an 
exclusive IPIA.
    (2) The State shall also demonstrate in its State Plan that it has 
the present capability to act as an IPIA for all plants operating in the 
State.

Sec. 3282.303  State plan--suggested provisions.

    The following are not required to be included in the State plan, but 
they are urged as necessary to provide full consumer protection and 
assurances of manufactured home safety:
    (a) Provision for monitoring of retailers' lots within the State for 
transit damage, seal tampering, and retailer performance generally,
    (b) Provision of approvals of all alterations made to certified 
manufactured homes by retailer in the State. Under this program, the 
State would assure that alterations did not result in the failure of the 
manufactured home to comply with the standards.
    (c) Provision for monitoring of the installation of manufactured 
homes set up in the State to assure that the homes are properly 
installed and, where necessary, tied down,
    (d) Provision for inspection of used manufactured homes and 
requirements under State authority that used manufactured homes meet a 
minimal level of safety and durability at the time of sale, and,
    (e) Provision for regulation of manufactured home transportation 
over the road to the extent that such regulation is not preempted by 
Federal authority.



Sec. 3282.304  Inadequate State plan.

    If the Secretary determines that a State plan submitted under this 
subpart is not adequate, the designated State agency shall be informed 
of the additions and corrections required for approval. A revised State 
plan shall be submitted within 30 days of receipt of such determination. 
If the revised State plan is inadequate or if the State fails to 
resubmit within the 30 day period or otherwise indicates that it does 
not intend to change its State plan as submitted, the Secretary shall 
notify the designated State agency that the State plan is not approved 
and that it has a right to a hearing on the disapproval in accordance 
with subpart D of this part.



Sec. 3282.305  State plan approval.

    The Secretary's approval or conditional approval of a State plan 
Application shall qualify that State to perform the functions for which 
it has been approved.



Sec. 3282.306  Withdrawal of State approval.

    The Secretary shall, on the basis of reports submitted by the State, 
and on the basis of HUD monitoring, make a continuing evaluation of the 
manner in which each State is carrying out its State plan and shall 
submit the reports of such evaluation to the appropriate committees of 
the Congress. Whenever the Secretary finds, after affording due notice 
and opportunity for a hearing in accordance with subpart D of this part, 
that in the administration of the State program there is a failure to 
comply substantially with any provision of the State plan or that the 
State plan has become inadequate, the Secretary shall notify the State 
of withdrawal of approval or conditional approval of the State program. 
The State program shall cease to be in effect at such time as the 
Secretary may establish.



Sec. 3282.307  Monitoring inspection fee establishment and distribution.

    (a) Each approved State shall establish a monitoring inspection fee 
in an amount required by the Secretary. This fee shall be an amount paid 
by each manufactured home manufacturer in the State for each 
transportable section of each manufactured housing unit produced by the 
manufacturer in that

[[Page 165]]

State. In non-approved and conditionally-approved States, the fee shall 
be set by the Secretary.
    (b) The monitoring inspection fee shall be paid by the manufacturer 
to the Secretary or to the Secretary's Agent, who shall distribute a 
portion of the fees collected from all manufactured home manufacturers 
among the approved and conditionally-approved States in accordance with 
an agreement between the Secretary and the States and based upon the 
following formula:
    (1) $9.00 of the monitoring inspection fee collected for each 
transportable section of each new manufactured housing unit that, after 
leaving the manufacturing plant, is first located on the premises of a 
retailer, distributor, or purchaser in that State; plus
    (2) $2.50 of the monitoring inspection fee collected for each 
transportable section of each new manufactured housing unit produced in 
a manufacturing plant in that State.
    (c) A portion of the monitoring inspection fee collected also shall 
be distributed by the Secretary or the Secretary's Agent based on the 
extent of participation of the State in the Joint Team Monitoring 
Program set out in Sec. 3282.308.
    (d) To assure that a State devotes adequate funds to carry out its 
State Plan, a State may impose an additional reasonable inspection fee 
to offset expenses incurred by that State in conducting inspections. 
Such fee shall not exceed that amount which is the difference between 
the amount of funds distributed to the State as provided in paragraph 
(b) of this section and the amount necessary to cover the costs of 
inspections. Such fee shall be part of the State Plan pursuant to Sec. 
3282.302(b) (11) and (12) and shall be subject to the approval of the 
Secretary pursuant to Sec. 3282.305.
    (e) The Secretary may establish by notice in the Federal Register a 
monitoring inspection fee which is to be paid by manufacturers for each 
transportable section of each manufactured housing unit manufactured in 
nonapproved and conditionally approved States as described in Sec. 
3282.210. To determine the amount of the inspection fee to be paid for 
each transportable section of each manufactured home, the Secretary 
shall divide the (estimated) number of transportable sections of 
manufactured homes (based on recent industry production figures) into 
the anticipated aggregate cost of conducting the inspection program in 
the foreseeable feature. The time period selected for projecting the 
Department's inspection-related costs and number of transportable 
sections need not always be the same, but must be for a period of 
sufficient duration to provide for access to reasonable underlying data. 
To determine the aggregate cost of conducting the inspection program, 
the Secretary shall calculate the sum necessary to support:
    (1) Inspection-related activities of State Administrative Agencies;
    (2) Inspection-related activities performed by the Department of 
Housing and Urban Development;
    (3) Inspection-related activities performed by monitoring inspection 
contractors;
    (4) Miscellaneous activities involving the performance of 
inspection-related activities by the Department, including on-site 
inspections on an ad hoc basis; and
    (5) Maintenance of adequate funds to offset short-term fluctuations 
in costs that do not warrant revising the fee under the authority of 
this section.
    (f) The Secretary may at any time revise the amount of the fees 
established under paragraph (a) or (e) of this section by placing a 
notice of the amount of the revised fee in the Federal Register.

Sec. 3282.308  State participation in monitoring of primary inspection agencies.

    (a) An SAA may provide personnel to participate in joint team 
monitoring of primary inspection agencies as set out in subpart J. If an 
SAA wishes to do so, it must include in its State plan a list of what 
personnel would be supplied for the teams, their qualifications, and how 
many person-years the State would supply. All personnel will be subject 
to approval by the Secretary or the Secretary's agent. A person-year is 
2,080 hours of work.

[[Page 166]]

    (b) If an SAA wishes to monitor the performance of primary 
inspection agencies acting within the State, it must include in its 
State plan a description of how extensively, how often, and by whom this 
will be carried out. This monitoring shall be coordinated by the 
Secretary, or the Secretary's agent with monitoring carried out by joint 
monitoring teams, and in no event shall an SAA provide monitoring where 
the State is also acting as a primary inspection agency.



Sec. 3282.309  Formal and informal presentations of views held by SAAs.

    (a) When an SAA is the appropriate agency to hold a Formal or 
Informal Presentation of Views under Sec. 3282.412 of subpart I, the 
SAA shall follow the procedures set out in Sec. Sec. 3282.152 and 
3282.153, with the SAA acting as the Secretary otherwise would under 
that section. Where Sec. 3282.152 requires publication of notice in the 
Federal Register, the SAA shall, to the maximum extent possible, provide 
equivalent notice throughout the State by publication in the newspaper 
or newspapers having statewide coverage or otherwise. The determination 
of whether to provide an Informal Presentation of Views under Sec. 
3282.152(f), or a Formal Presentation of Views under Sec. 3282.152(g), 
is left to the SAA.
    (b) Notwithstanding the provisions of Sec. 3282.152(f)(2) and 
(g)(2) relating to the conclusive effect of a final determination, any 
party, in a proceeding held at an SAA under this section, including 
specifically the owners of affected manufactured homes, States in which 
affected manufactured homes are located, consumer groups representing 
affected owners and manufacturers (but limited to parties with similar 
substantial interest) may appeal to the Secretary in writing any Final 
Determination by an SAA which is adverse to the interest of that party. 
This appeal on the record shall be made within 30 days of the date on 
which the Final Determination was made by the SAA.

                  Subpart H_Primary Inspection Agencies



Sec. 3282.351  General.

    (a) This subpart sets out the requirements which must be met by 
States or private organizations which wish to qualify as primary 
inspection agencies under these regulations. It also sets out the 
various functions which will be carried out by primary inspection 
agencies.
    (b) There are four basic functions which are performed by primary 
inspection agencies:
    (1) Approval of the manufacturer's manufactured home design to 
assure that it is in compliance with the standard;
    (2) Approval of the manufacturer's quality control program to assure 
that it is compatible with the design;
    (3) Approval of the manufacturer's plant facility and manufacturing 
process to assure that the manufacturer can perform its approved quality 
control program and can produce manufactured homes in conformance with 
its approved design, and
    (4) Performance of ongoing inspections of the manufacturing process 
in each manufacturing plant to assure that the manufacturer is 
continuing to perform its approved quality control program and, with 
respect to those aspects of manufactured homes inspected, is continuing 
to produce manufactured homes in performance with its approved designs 
and in conformance with the standards (see Sec. 3282.362(c)(1)).
    (c) There are two types of primary inspection agencies which perform 
these functions:
    (1) Those which approve designs and quality control programs (Design 
Approval Primary Inspection Agencies--DAPIAs) and
    (2) Those which approve plants and perform ongoing inspections in 
the manufacturing plants (Production Inspection Primary Inspection 
Agencies--IPIAs).
    (d) States and private organizations whose submissions under this 
subpart are acceptable shall be granted provisional acceptance. Final 
acceptance shall be conditioned upon adequate performance, which will be 
determined

[[Page 167]]

through monitoring of the actions of the primary inspection agencies. 
Monitoring of all primary inspection agencies shall be carried out as 
set out in subpart J. HUD accepted agencies can perform DAPIA functions 
for any manufacturer in any State and IPIA functions in any State except 
those in which the State has been approved to act as the exclusive IPIA 
under Sec. 3282.352.
    (e) Primary inspection agencies approved under this subpart may 
contract with manufactured home manufacturers (see Sec. 3282.202) to 
provide the services set out in this subpart. Any PIA which charges fees 
which are excessive in relation to the services rendered shall be 
subject to disqualification under Sec. 3282.356.



Sec. 3282.352  State exclusive IPIA functions.

    (a) Any State which has an approved State Administrative Agency may, 
if accepted as an IPIA, act as the exclusive IPIA within the State. A 
State which acts as an IPIA but is not approved as an SAA may not act as 
the exclusive IPIA in the State. A State which acts as an exclusive IPIA 
shall be staffed to provide IPIA services to all manufacturers within 
the state and may not charge unreasonable fees for those services.
    (b) States which wish to act as exclusive IPIAs shall apply for 
approval to do so in their State plan applications. They shall specify 
the fees they will charge for IPIA services and shall submit proposed 
fee revisions to the Secretary prior to instituting any change in fees. 
If at any time the Secretary finds that those fees are not commensurate 
with the fees generally being charged for similar services, the 
Secretary will withhold or revoke approval to act as an exclusive IPIA. 
States acting as DAPIAs and also as exclusive IPIAs shall establish 
separate fees for the two functions and shall specify what additional 
services (such as approval of design changes and full time inspections) 
these fees cover. As provided in Sec. 3282.302(b)(11), each State shall 
submit fee schedules for its activities and, where appropriate, the fees 
presently charged for DAPIA and IPIA services, and any fees charged for 
DAPIA and IPIA services during the preceding two calendar years.
    (c) A State's status as an exclusive IPIA shall commence upon 
approval of the State Plan Application and acceptance of the State's 
submission under Sec. 3282.355. Where a private organization accepted 
or provisionally accepted as an IPIA under this subpart H is operating 
in a manufacturing plant within the State on the date the State's status 
as an exclusive IPIA commences, the private organization may provide 
IPIA services in that plant for 90 days after that date.

[61 FR 10861, Mar. 15, 1996]

    (b) A detailed schedule of fees to be charged broken down by the 
services for which they will be charged.
    (c) A detailed description of how the submitting party intends to 
carry out all of the functions for which it wishes to be approved under 
this subpart, with appropriate cross-references to sections of this 
subpart, including examples and complete descriptions of all reports, 
tests, and evaluations which the party would be required to make. Where 
appropriate, later sections of this subpart identify particular items 
which must be included in the submission. The Secretary may request 
further detailed information, when appropriate.
    (d) A party wishing to be approved as a DAPIA shall submit a copy of 
a manufactured home design that it has approved (or if it has not 
approved a design, one that it has evaluated and a deviation report 
showing where the design is not in conformance with the standards) and a 
copy of a quality assurance manual that it has approved (or if it was 
not approved a manual, one that it has evaluated and a deviation report 
showing where the manual is inadequate).
    (e) A party wishing to be approved as an IPIA shall submit a copy of 
a certification report which it has prepared for a manufactured home 
plant or, if it has not prepared such a report, an evaluation of a 
manufacturing plant which it has inspected with a description of what 
changes shall be made before a certification report can be issued. A 
party that has not previously inspected manufactured homes may 
nevertheless be accepted on the basis of the qualifications of its 
personnel and its commitment to perform the required functions.

FR 60199, Oct. 1, 2013]



Sec. 3282.354  Submittal of false information or refusal to submit
information.

    The submittal of false information or the refusal to submit 
information required under this subpart may be sufficient cause for the 
Secretary to revoke or withhold acceptance.



Sec. 3282.355  Submission acceptance.

    (a) A party whose submission is determined by the Department to be 
adequate shall be granted provisional acceptance until December 15, 
1976, or for a six month period from the date of such determination, 
whichever is later.
    (b) Final acceptance of a party to act as a primary inspection 
agency will be contingent upon adequate performance during the period of 
provisional acceptance as determined through monitoring carried out 
under subpart J and upon satisfactory acceptance under Sec. 3282.361(e) 
or Sec. 3282.362(e). Final acceptance shall be withheld if performance 
is inadequate.
    (c) Continued acceptance as a primary inspection agency shall be 
contingent upon continued adequacy of performance as determined through 
monitoring carried out under subpart J. If the Secretary determines that 
a primary inspection agency that has been granted final acceptance is 
performing inadequately, the Secretary shall suspend the acceptance, and 
the primary inspection agency shall be entitled to a Formal or Informal 
Presentation of Views as set out in subpart D of this part.

[41 FR 19852, May 13, 1976, as amended at 51 FR 34468, Sept. 29, 1986; 
61 FR 10861, Mar. 15, 1996]



Sec. 3282.356  Disqualification and requalification of primary
inspection agencies.

    (a) The Secretary, based on monitoring reports or on other reliable 
information, may determine that a primary inspection agency which has 
been accepted under this subpart is not adequately carrying out one or 
more of its required functions. In so determining, the Secretary shall 
consider the impact of disqualification on manufacturers and other 
affected parties and shall seek to assure that the manufacturing process 
is not disrupted unnecessarily. Whenever the Secretary disqualifies a 
primary inspection agency under this section, the primary inspection 
agency shall have a right to a Formal or Informal Presentation of Views 
under subpart D of this part.
    (b) Interested persons may petition the Secretary to disqualify a 
primary

[[Page 169]]

inspection agency under the provisions of Sec. 3282.156(b).
    (c) A primary inspection agency which has been disqualified under 
paragraph (a) may resubmit an application under Sec. 3282.353. The 
submission shall include a full explanation of how problems or 
inadequacies which resulted in disqualifications have been rectified and 
how the primary inspection agency shall assure that such problems shall 
not recur.
    (d) When appropriate, the Secretary shall publish in the Federal 
Register or otherwise make available to the public for comment a 
disqualified PIA's application for requalification, subject to the 
provisions of Sec. 3282.54.
    (e) Both provisional and final acceptance of any IPIA (or DAPIA) 
automatically expires at the end of any period of one year during which 
it has not acted as an IPIA (or DAPIA). An IPIA (or DAPIA) has not acted 
as such unless it has actively performed its services as an IPIA (or 
DAPIA) for at least one manufacturer by which it has been selected. An 
IPIA (or DAPIA) whose acceptance has expired pursuant to this section 
may resubmit an application under Sec. 3282.353 in order to again be 
qualified as an IPIA (or DAPIA), when it can show a bona fide prospect 
of performing IPIA (or DAPIA) services.

organizations' experience in the housing industry, including a list of 
housing products, equipment, and structures for which evaluation, 
testing and follow-up inspection services have been furnished. They 
shall also submit statements regarding the length of time these services 
have been provided by them. In addition, all such submissions shall 
include a list of other products for which the submitting party provides 
evaluation, inspection, and listing or labeling services and the 
standard applied to each product, as well as the length of time it has 
provided these additional services.



Sec. 3282.358  Personnel.

    (a) Each primary inspection agency shall have qualified personnel 
capable of carrying out all of the functions for which the primary 
inspection agency is seeking to be approved or disapproved. Where a 
State intends to act as the exclusive IPIA in the State, it shall show 
that it has adequate personnel to so act in all plants in the State.
    (b) Each submission shall indicate the total number of personnel 
employed by the submitting party, the number of personnel available for

Sec. 3282.360  PIA acceptance of product certification programs or listings.

    In determining whether products to be included in a manufactured 
home are acceptable under the standards set out in part 3280 of 24 CFR, 
all PIAs shall accept all product verification programs, labelings, and 
listings unless the PIA has reason to believe that a particular 
certification is not acceptable, in which case, the PIA shall so inform 
the Secretary and provide the Secretary with full documentation and 
information on which it bases its belief. Pending a determination by the 
Secretary, the PIA shall provisionally accept the certification. The 
Secretary's determination shall be binding on all PIAs.

Sec. 3282.361  Design Approval Primary Inspection Agency (DAPIA).

    (a) General. (1) The DAPIA selected by a manufacturer under Sec. 
3282.203 shall be responsible for evaluating all manufactured home 
designs submitted to it by the manufacturer and for assuring that they 
conform to the standards. It shall also be responsible for evaluating 
all quality control programs submitted to it by the manufacturer by 
reviewing the quality assurance manuals in which the programs are set 
out to assure that the manuals reflect programs which are compatible 
with the designs to be followed and which commit the manufacturer to 
make adequate inspections and tests of every part of every manufactured 
home produced.
    (2) A design or quality assurance manual approved by a DAPIA shall 
be accepted by all IPIAs acting under Sec. 3282.362 who deal with the 
design, quality assurance manual, or manufactured homes built to them, 
and by all other parties, as, respectively, being in conformance with 
the Federal standards or as providing for adequate quality control to 
assure conformance. However, each design and quality assurance manual is 
subject to review and verification by the Secretary or the Secretary's 
agent at any time.
    (b) Designs. (1) In evaluating designs for compliance with the 
standards, the DAPIA will not allow any deviations from accepted 
engineering practice standards for design calculations or any deviations 
from accepted test standards, except that the DAPIA, for good cause, may 
request the Secretary to accept innovations which are not yet accepted 
practices. Acceptances by the Secretary shall be published in the form 
of interpretative bulletins, where appropriate.
    (2) The DAPIA shall require the manufacturer to submit floor plans 
and specific information for each manufactured home design or variation 
which the DAPIA is to evaluate. It shall also require the submission of 
drawings, specifications, calculations, and test records of the 
structural, electrical and mechanical systems of each such manufactured 
home design or variation. The manufacturer need not supply duplicate 
information where systems are common to several floor plans. Each DAPIA 
shall develop and carry out procedures for evaluating original 
manufactured home designs by requiring manufacturers to submit necessary 
drawings and calculations and carry out such verifications and 
calculations as it deems necessary. Where compliance with the standards 
cannot be determined on the basis of drawings and calculations, the 
DAPIA shall require any necessary tests to be carried out at its own 
facility, at separate testing facilities or at the manufacturer's plant.
    (3) Design deviation report. After evaluating the manufacturer's 
design, the DAPIA shall furnish the manufacturer with a design deviation 
report which specifies in detail, item by item with appropriate 
citations to the standards, the specific deviations in the 
manufacturer's design which must be rectified in order to produce 
manufactured homes which comply with the standards. The design deviation 
report may acknowledge the possibility of alternative designs, tests, 
listings, and certifications and state the conditions under which they 
will be acceptable. The design deviation report shall, to the extent 
practicable, be complete for each design evaluated in order to avoid 
repeated rejections and additional costs to the manufacturer.
    (4) Design approval. The DAPIA shall signify approval of a design by 
placing its stamp of approval or authorized signature on each drawing 
and each sheet of test results. The DAPIA shall clearly cross-reference 
the calculations and test results to applicable drawings. The DAPIA may 
require the manufacturer to do the cross-referencing if it wishes. It 
shall indicate on each sheet how any deviations from the standards have 
been or shall be resolved. Within 5 days after approving a design, the 
DAPIA shall forward a copy of the design to the manufacturer and the 
Secretary or the Secretary's agent (prior to the effective date of the 
standards the latter copy shall go to the Secretary.)

The DAPIA shall maintain a complete up-to-date set of approved designs 
and design changes approved under paragraph (b)(5) of this section which 
it can duplicate and copies of which it can furnish to interested 
parties as needed when disputes arise.

[[Page 172]]

    (5) Design change approval. The DAPIA shall also be responsible for 
approving all changes which a manufacturer wishes to make in a design 
approved by the DAPIA. In reviewing design changes, the DAPIA shall 
respond as quickly as possible to avoid disruption of the manufacturing 
process. Within 5 days after approving a design change, the DAPIA shall 
forward a copy of this change to the manufacturer and the Secretary or 
the Secretary's agent as set out in paragraph (b)(4) of this section to 
be included in the design to which the change was made.
    (c) Quality assurance manuals. (1) In evaluating a quality assurance 
manual, the DAPIA shall identify any aspects of designs to be 
manufactured under the manual which require special quality control 
procedures. The DAPIA shall determine whether the manual under which a 
particular design is to be manufactured reflects those special 
procedures, and shall also determine whether the manuals which it 
evaluates provide for such inspections and testing of each manufactured 
home so that the manufacturer, by following the manual, can assure that 
each manufactured home it manufactures will conform to the standards. 
The manual shall, at a minimum, include the information set out in Sec. 
3282.203(c).
    (2) Manual deviation report. After evaluating a manufacturer's 
quality assurance manual, the DAPIA shall furnish the manufacturer with 
a manual deviation report which specifies in detail any changes which a 
manufacturer must make in order for the quality assurance manual to be 
acceptable. The manual deviation report shall, to the extent 
practicable, be complete for each design in order to avoid repeated 
rejections and additional costs to the manufacturer.
    (3) Manual approval. The DAPIA shall signify approval of the 
manufacturer's quality assurance manual by placing its stamp of approval 
or authorized signature on the cover page of the manual. Within 5 days 
of approving a quality assurance manual, the DAPIA shall forward a copy 
of the quality assurance manual to the manufacturer and the Secretary or 
the Secretary's agent (prior to the effective date of the standards, the 
latter copy shall go to the Secretary). The DAPIA shall maintain a 
complete up-to-date set of approved manuals and manual changes approved 
under paragraph (c)(4) of this section which it can duplicate and copies 
of which it can furnish to interested parties as needed when disputes 
arise.
    (4) Manual change approval. Each change the manufacturer wishes to 
make in its quality assurance manual shall be approved by the DAPIA. 
Within 5 days after approving a manual change, the DAPIA shall forward a 
copy of the change to the manufacturer and the Secretary or the 
Secretary's agent as set out in paragraph (c)(3) of this section to be 
included in the manual to which the change was made.
    (d) Requirements for full acceptance--DAPIA. (1) Before granting 
full acceptance to a DAPIA, the Secretary or the Secretary's agent shall 
review and evaluate at least one complete design and one quality 
assurance manual which has been approved by the DAPIA. These shall be 
designs and manuals approved to the Federal standards, and they shall be 
chosen at random from those approved by the DAPIA during the period of 
provisional acceptance.
    (2) If the Secretary determines that a design or quality assurance 
manual shows an inadequate level of performance, the Secretary or the 
Secretary's agent shall carry out further evaluations. If the Secretary 
finds the level of performance to be unacceptable, the Secretary shall 
not grant full acceptance. If full acceptance has not been granted by 
the end of the provisional acceptance period, provisional acceptance 
shall lapse unless the Secretary determines that the failure to obtain 
full acceptance resulted from the fact that the Secretary or her agent 
has not had adequate time in which to complete an evaluation.

Sec. 3282.362  Production Inspection Primary Inspection Agencies (IPIAs).

    (a) General--(1) IPIA responsibilities. An IPIA selected by a 
manufacturer under Sec. 3282.204 to act in a particular manufacturing 
plant shall be responsible for assuring:

[[Page 173]]

    (i) That the plant is capable of following the quality control 
procedures set out in the quality assurance manual to be followed in 
that plant;
    (ii) That the plant continues to follow the quality assurance 
manual;
    (iii) That any part of any manufactured home that it actually 
inspects conforms with the design, or where the design is not specific 
with respect to an aspect of the standards, to the standards;
    (iv) That whenever it finds a manufactured home in production which 
fails to conform to the design or where the design is not specific, to 
the standards, the failure to conform is corrected before the 
manufactured home leaves the manufacturing plant; and
    (v) That if a failure to conform to the design, or where the design 
is not specific, to the standards, is found in one manufactured home, 
all other homes still in the plant which the IPIA's records or the 
records of the manufacturer indicate might not conform to the design or 
to standards are inspected and, if necessary, brought up to the 
standards before they leave the plant.
    (2) No more than one IPIA shall operate in any one manufacturing 
plant, except that where a manufacturer decides to change from one IPIA 
to another, the two may operate in the plant simultaneously for a 
limited period of time to the extent necessary to assure a smooth 
transition.
    (b) Plant approval. (1) Each IPIA shall, with respect to each 
manufacturing plant for which it is responsible, evaluate the quality 
control procedures being followed by the manufacturer in the plant to 
determine whether those procedures are consistent with and fulfill the 
procedures set out in the DAPIA approved quality assurance manual being 
followed in the plant. As part of this evaluation, and prior to the 
issuance of any labels to the manufacturer, the IPIA shall make a 
complete inspection of the manufacture of at least one manufactured home 
through all of the operations in the manufacturer's plant. The purpose 
of this initial factory inspection is to determine whether the 
manufacturer is capable of producing manufactured homes in conformance 
with the approved design and, to the extent the design is not specific 
with respect to an aspect of the standards, with the standards and to 
determine whether the manufacturer's quality control procedures as set 
out in the quality assurance manual, plant equipment, and personnel, 
will assure that such conformance continues. This inspection should be 
made by one or more qualified engineers who have reviewed the approved 
design and by an inspector who has been carefully briefed by the 
engineers on the restrictive aspects of the design. The manufactured 
home shall be inspected to the approved design for the home except that 
where the design is not specific with respect to any aspect of the 
standards, the inspection shall be to the standards as to that aspect of 
the manufactured home. If the first manufactured home inspected fails to 
conform to the design or, with respect to any aspect of the standards 
not specifically covered by the design, to the standards, additional 
units shall be similarly inspected until the IPIA is satisfied that the 
manufacturer is conforming to the approved design, or where the design 
is not specific with respect to any aspect of the standards, to the 
standards and quality assurance manual.
    (2) Certification report. If, on the basis of the initial 
comprehensive factory inspection required by paragraph (b)(1) of this 
section, the IPIA determines that the manufacturer is performing 
adequately, the IPIA shall prepare and forward to the manufacturer, to 
HUD, and to HUD's agent a certification report as described in this 
paragraph (b)(2) of this section. The issuance of the certification 
report is a prerequisite to the commencement of production surveillance 
under paragraph (c) of this section in the plant for which the report is 
issued. At the time the certification report is issued, the IPIA may 
provide the manufacturer with a two to four week supply of labels to be 
applied to manufactured homes produced in the plant. The IPIA shall 
maintain a copy of each certification report which it issues.
    (3) The certification report shall include:
    (i) The name of the DAPIA which approved the manufacturer's design 
and

[[Page 174]]

quality assurance manual and the dates of those approvals,
    (ii) The names and titles of the IPIA engineers and inspectors who 
performed the initial comprehensive inspection,
    (iii) A full report of inspections made, serial numbers inspected, 
any failures to comply which were observed, corrective actions taken, 
and dates of inspections, and
    (iv) A certification that at least one manufactured home has been 
completely inspected in all phases of its production in the plant, that 
the manufacturer is performing in conformance with the approved designs 
and quality assurance manual and, to the extent the design is not 
specific with respect to any aspects of the standards, with the 
standards, and the IPIA is satisfied that the manufacturer can produce 
manufactured homes in conformance with the designs, and where the 
designs are not specific, with the standards on a continuing basis.
    (4) Inadequate manufacturer performance. Where an IPIA determines 
that the performance of a manufacturer is not yet adequate to justify 
the issuance of a certification report and labels to the manufacturer, 
the IPIA may label manufactured homes itself by using such of its 
personnel as it deems necessary to perform complete inspections of all 
phases of production of each manufactured home being produced and 
labeling only those determined after any necessary corrections to be in 
conformance with the design and, as appropriate, with the standards. 
This procedure shall continue until the IPIA determines that the 
manufacturer's performance is adequate to justify the issuance of a 
certification report.
    (c) Production surveillance. (1) After it has issued a certification 
report under paragraph (b) of this section, the IPIA shall carry out 
ongoing surveillance of the manufacturing process in the plant. The IPIA 
shall be responsible for conducting representative inspections to assure 
that the manufacturer is performing its quality control program pursuant 
to and consistent with its approved quality assurance manual and to 
assure that whatever part of a manufactured home is actually inspected 
by the IPIA is fully in conformance with the design and, as appropriate 
under paragraph (a)(1)(iii) of this section, with the standards before a 
label is issued for or placed on that manufactured home. The 
surveillance visits shall commence no later than that date on which the 
IPIA determines they must commence so that the IPIA can assure that 
every manufactured home to be produced after the effective date of the 
standards to which a label provided for in paragraph (c)(2) of this 
section is affixed, is inspected in at least one stage of its 
production. The frequency of subsequent visits to the plant shall 
continue to be such that every manufactured home is inspected at some 
stage in its production. In the course of each visit, the IPIA shall 
make a complete inspection of every phase of production and of every 
visible part of every manufactured home which is at each stage of 
production. The inspection shall be made to the approved design except 
where the design is not specific with respect to an aspect of the 
standards, in which case the inspection of that aspect of the 
manufactured home shall be made to the standards. The IPIA shall assure 
that no label is placed on any manufactured home which it finds fails to 
conform with the approved design or, as appropriate, the standards in 
the course of these inspections and shall assure that no labels are 
placed on other manufactured homes still in the plant which may also not 
conform until those homes are inspected and if necessary corrected to 
the design or the standards. If an IPIA finds a manufactured home that 
fails to conform to the design, or as appropriate under paragraph 
(a)(1)(iii) of this section, to the standards, the IPIA may, in addition 
to withholding the label for the unit, proceed to red tag the home until 
the failure to conform is corrected. Only the IPIA is authorized to 
remove a red tag. When manufactured homes repeatedly fail to conform to 
the design, or as appropriate under paragraph (a)(1)(iii) of this 
section, to the standards in the same assembly station or when there is 
evidence that the manufacturer is ignoring or not performing under its 
approved quality assurance manual, the IPIA shall increase the frequency 
of

[[Page 175]]

these inspections until it is satisfied that the manufacturer is 
performing to its approved quality assurance manual. Failure to perform 
to the approved manual justifies withholding labels until an adequate 
level of performance is attained. As part of its function of assuring 
quality control, the IPIA shall inspect materials in storage and test 
equipment used by the manufacturer at least once a month, and more 
frequently if unacceptable conditions are observed. With the prior 
approval of the Secretary, an IPIA may decrease the frequency of any 
inspections.
    (2) Labeling--(i) Labels required. (A) The IPIA shall continuously 
provide the manufacturer with a two- to four-week supply (at the 
convenience of the IPIA and the manufacturer) of the labels described in 
this subsection, except that no labels shall be issued for use when the 
IPIA is not present if the IPIA is not satisfied that the manufacturer 
can and is producing manufactured homes which conform to the design and, 
as appropriate, to the standards. Where necessary, the IPIA shall 
reclaim labels already given to the manufacturer. In no event shall the 
IPIA allow a label to be affixed to a manufactured home if the IPIA 
believes that the manufactured home fails to conform to the design, or, 
where the design is not specific with respect to an aspect of the 
standards, to the standards. Labels for such manufactured homes shall be 
provided only after the failure to conform has been remedied, or after 
the Secretary has determined that there is no failure to conform.
    (B) A permanent label shall be affixed to each transportable section 
of each manufactured home for sale or lease to a purchaser or lessor in 
the United States in such a manner that removal will damage the label so 
that it cannot be reused. This label is provided by the IPIA and is 
separate and distinct from the data plate that the manufacturer is 
required to provide under Sec. 3280.5.
    (C) The label shall read as follows:

    ``As evidenced by this label No. ABC 000 001, the manufacturer 
certifies to the best of the manufacturer's knowledge and belief that 
this manufactured home has been inspected in accordance with the 
requirements of the Department of Housing and Urban Development and is 
constructed in conformance with the Federal Manufactured Home 
Construction and Safety Standards in effect on the date of manufacture. 
See data plate.''

    (D) The label shall be 2 in. by 4 in. in size and shall be 
permanently attached to the manufactured home by means of 4 blind 
rivets, drive screws, or other means that render it difficult to remove 
without defacing it. It shall be etched on .032 in. thick aluminum 
plate. The label number shall be etched or stamped with a 3 letter IPIA 
designation which the Secretary shall assign and a 6 digit number which 
the label supplier shall stamp sequentially on labels supplied to each 
IPIA.
    (E) The label shall be located at the tail-light end of each 
transportable section of the manufactured home approximately one foot up 
from the floor and one foot in from the road side, or as near that 
location on a permanent part of the exterior of the manufactured home as 
practicable. The roadside is the right side of the manufactured home 
when one views the manufactured home from the tow bar end of the 
manufactured home. It shall be applied to the manufactured home unit in 
the manufacturing plant by the manufacturer or the IPIA, as appropriate.
    (F) The label shall be provided to the manufacturer only by the 
IPIA. The IPIA shall provide the labels in sequentially numbered series. 
The IPIA may obtain labels from the Secretary or the Secretary's agent, 
or where the IPIA obtains the prior approval of the Secretary, from a 
label manufacturer. However, if the IPIA obtains labels directly from a 
label supplier, those labels must be sequentially numbered without any 
duplication of label numbers.
    (G) Whenever the IPIA determines that a manufactured home which has 
been labeled, but which has not yet been released by the manufacturer 
may not conform to the design or, as appropriate under paragraph 
(a)(1)(iii) of this section, to the standards, the IPIA by itself or 
through an agent shall red tag the manufactured home. Where the IPIA 
determines that a manufactured home which has been labeled and released 
by the manufacturer, but not yet sold to a purchaser (as described in

[[Page 176]]

Sec. 3282.252(b)) may not conform, the IPIA may, in its discretion, 
proceed to red tag the manufactured home. Only the IPIA is authorized to 
remove red tags, though it may do so through agents which it deems 
qualified to determine that the failure to conform has been corrected. 
Red tags may be removed when the IPIA is satisfied, through inspections, 
assurances from the manufacturer, or otherwise, that the affected homes 
conform.
    (H) Labels that are damaged, destroyed, or otherwise made illegible 
or removed shall be replaced by the IPIA, after determination that the 
manufactured home is in compliance with the standards, by a new label of 
a different serial number. The IPIA's labeling record shall be 
permanently marked with the number of the replacement label and a 
corresponding record of the replacement label.
    (ii) Label control. The labels used in each plant shall be under the 
direct control of the IPIA acting in that plant. Only the IPIA shall 
provide the labels to the manufacturer. The IPIA shall assure that the 
manufacturer does not use any other label to indicate conformance to the 
standards.
    (A) The IPIA shall be responsible for obtaining labels. Labels shall 
be obtained from HUD or its agent, or with the approval of the 
Secretary, from a label manufacturer. The labels shall meet the 
requirements of this section. Where the IPIA obtains labels directly 
from a label manufacturer, the IPIA shall be responsible for assuring 
that the label manufacturer does not provide labels directly to the 
manufacturer of manufactured homes. If the label manufacturer fails to 
supply correct labels or allows labels to be released to parties other 
than the IPIA, the IPIA shall cease dealing with the label manufacturer.
    (B) The labels shall be shipped to and stored by the IPIA's at a 
location which permits ready access to manufacturing plants under its 
surveillance. The labels shall be stored under strict security and 
inventory control. They shall be released only by the IPIA to the 
manufacturer under these regulations.
    (C) The IPIA shall be able to account for all labels which it has 
obtained through the date on which the manufactured home leaves the 
manufacturing plant, and it shall be able to identify the serial number 
of the manufactured home to which each particular label is affixed.
    (D) The IPIA shall keep in its central record office a list of the 
serial numbers of labels issued from the label producer to the IPIA and 
by the IPIA to the manufacturing plant.
    (E) Failure to maintain control of labels through the date the 
manufactured home leaves the manufacturing plant and failure to keep 
adequate records of which label is on which manufactured home shall 
render the IPIA subject to disqualification under Sec. 3282.356.
    (3) Data plate. (i) The IPIA shall assure that each manufactured 
home produced in each manufacturing plant under its surveillance is 
supplied with a data plate which meets the requirements of this section 
and of Sec. 3280.5 of chapter XX of 24 CFR. The data plate shall be 
furnished by the manufacturer and affixed inside the manufactured home 
on or near the main electrical distribution panel. The data plate shall 
contain the following information:
    (A) The name and address of the manufacturing plant in which the 
manufactured home was manufactured,
    (B) The serial number and model designation of the unit and the date 
the unit was manufactured,
    (C) The statement ``This manufactured home is designed to comply 
with the Federal Manufactured Home Construction and Safety Standards in 
force at the time of manufacture.'',
    (D) A list of major factory-installed equipment including the 
manufacturer's name and the model designation of each appliance,
    (E) Reference to the roof load zone and wind load zone for which the 
home is designed and duplicates of the maps as set forth in Sec. 
3280.305. This information may be combined with the heating/cooling 
certificate and insulation zone map required by Sec. Sec. 3280.510 and 
3280.511. The Wind Zone Map on the Data Plate shall also contain the 
statement:

    This home has not been designed for the higher wind pressures and 
anchoring provisions required for ocean/coastal areas and

[[Page 177]]

should not be located within 1500[foot] of the coastline in Wind Zones 
II and III, unless the home and its anchoring and foundation system have 
been designed for the increased requirements specified for Exposure D in 
ANSI/ASCE 7-88.

    (F) The statement:

    This home has ---- has not ---- (appropriate blank to be checked by 
manufacturer) been equipped with storm shutters or other protective 
coverings for windows and exterior door openings. For homes designed to 
be located in Wind Zones II and III, which have not been provided with 
shutters or equivalent covering devices, it is strongly recommended that 
the home be made ready to be equipped with these devices in accordance 
with the method recommended in the manufacturers printed instructions.

    (G) The statement: ``Design Approval by'', followed by the name of 
the agency that approved the design.
    (ii) A copy of the data plate shall be furnished to the IPIA, and 
the IPIA shall keep a permanent record of the data plate as part of its 
labeling record so that the information is available during the life of 
the manufactured home in case the data plate in the manufactured home is 
defaced or destroyed.
    (d) Permanent records. The IPIA shall maintain the following records 
as appropriate:
    (1) Records of all labels issued, applied, removed, and replaced by 
label number, manufactured home serial number, manufactured home type, 
manufacturer's name, retailer destination, and copies of corresponding 
data plates.
    (2) Records of all manufactured homes which are red tagged, and the 
status of each home.
    (3) Records of all inspections made at each manufacturing plant on 
each manufactured home serial number, each failure to conform found, and 
the action taken in each case.
    (4) Records of all inspections made at other locations of 
manufactured homes identified by manufacturer and serial number, all 
manufactured homes believed to contain the same failure to conform, and 
the action taken in each case.

All records shall specify the precise section of the standard which is 
in question and contain a clear and concise explanation of the process 
by which the IPIA reached any conclusions. All records shall be 
traceable to specific manufactured home serial numbers and through the 
manufacturer's records to retailers and purchasers.
    (e) Requirements for full acceptance--IPIA. (1) Before granting full 
acceptance to an IPIA, the Secretary or the Secretary's agent shall 
review and evaluate at least one certification report which has been 
prepared by the IPIA during the period of provisional acceptance. The 
Secretary or the Secretary's agent shall also review in depth the IPIA's 
administrative capabilities and otherwise review the IPIA's performance 
of its responsibilities under these regulations.
    (2) Where the Secretary determines on the basis of these reviews 
that an IPIA is not meeting an adequate level of performance, the 
Secretary or the Secretary's agent shall carry out further evaluations. 
If the Secretary finds the level of performance to be unacceptable, the 
Secretary shall not grant full acceptance. If full acceptance has not 
been granted by the end of the provisional acceptance period, 
provisional acceptance shall lapse unless the Secretary determines that 
the failure to obtain full acceptance resulted from the fact that the 
Secretary or the Secretary's agent has not had adequate time in which to 
complete an evaluation.

1996]



Sec. 3282.363  Right of entry and inspection.

    Each primary inspection agency shall secure from each manufacturer 
and manufacturing plant under its surveillance an agreement that the 
Secretary, the State Administrative Agency and the primary inspection 
agency have the right to inspect the plant and its manufactured home 
inspection, labeling, and delivery records, and any of its manufactured 
homes in the hands of retailers or distributors at any reasonable time.

[[Page 178]]



Sec. 3282.364  Inspection responsibilities and coordination.

    All primary inspection agencies shall be responsible for acting as 
necessary under their contractual commitment with the manufacturer to 
determine whether alleged failures to conform to the standards may exist 
in manufactured homes produced under their surveillance and to determine 
the source of the problems. The DAPIA may be required to examine the 
designs in question or the quality assurance manual under which the 
manufactured homes were produced. The IPIA may be required to reexamine 
the quality control procedures which it has approved to determine if 
they conform to the quality assurance manual, and the IPIA shall have 
primary responsibility for inspecting actual units produced and, where 
necessary, for inspecting units released by the manufacturer. All 
primary inspection agencies acting with respect to particular 
manufacturer or plant shall act in close coordination so that all 
necessary functions are performed effectively and efficiently.



Sec. 3282.365  Forwarding monitoring fee.

    The IPIA shall, whenever it provides labels to a manufacturer, 
obtain from the manufacturer the monitoring fee to be forwarded to the 
Secretary or the Secretary's agent as set out in Sec. 3282.210. If a 
manufacturer fails to provide the monitoring fee as required by Sec. 
3282.210 to be forwarded by the IPIA under this section, the IPIA shall 
immediately inform the Secretary; or the Secretary's Agent.



Sec. 3282.366  Notification and correction campaign responsibilities.

    (a) Both IPIAs and DAPIAs are responsible for assisting the 
Secretary or an SAA in identifying the class of manufactured homes that 
may have been affected where the Secretary or an SAA makes or is 
contemplating making a preliminary determination of imminent safety 
hazard, serious defect, defect, or noncompliance under Sec. 3282.412 
with respect to manufactured homes for which the IPIA and DAPIA provided 
either plant inspection or design approval services.
    (b) The IPIA must in each manufacturing plant review at least 
monthly the manufacturer's service and inspection records to verify if 
appropriate determinations are being made by the manufacturer under 
Sec. 3282.404 and, if not, take the actions required by this section 
and Sec. 3282.404.
    (c) The IPIA in each manufacturing plant is also responsible for 
reviewing manufacturer determinations of the class of manufactured homes 
affected when the manufacturer is acting under subpart I. The IPIA must 
concur in the method used to determine the class of potentially affected 
manufactured homes or is to state why it finds the method to be 
inappropriate, inadequate, or incorrect.

       Subpart I_Consumer Complaint Handling and Remedial Actions

    Source: 78 FR 60200, Oct. 1, 2013, unless otherwise noted.



Sec. 3282.401  Purpose and scope.

    (a) Purpose. The purpose of this subpart is to establish a system of 
protections provided by the Act with respect to imminent safety hazards 
and failures to conform to the construction and safety standards with a 
minimum of formality and delay, while protecting the rights of all 
parties.
    (b) Scope. This subpart sets out the procedures to be followed by 
manufacturers, retailers, and distributors, SAAs, primary inspection 
agencies, and the Secretary to assure that notification and correction 
are provided with respect to manufactured homes when required under this 
subpart. Notification and correction may be required with respect to 
manufactured homes that have been sold or otherwise released by the 
manufacturer to another party.



Sec. 3282.402  General provisions.

    (a) Purchaser's rights. Nothing in this subpart shall limit the 
rights of the purchaser under any contract or applicable law.
    (b) Manufacturer's liability limited. A manufacturer is not 
responsible for

[[Page 179]]

failures that occur in any manufactured home or component as the result 
of normal wear and aging, consumer abuse, or neglect of maintenance. The 
life of a component warranty may be one of the indicators used to 
establish normal wear and aging. A failure of any component may not be 
attributed by the manufacturer to normal wear and aging under this 
subpart during the term of any applicable warranty provided by the 
original manufacturer of the affected component.



Sec. 3282.403  Consumer complaint and information referral.

    (a) Retailer responsibilities. When a retailer receives a consumer 
complaint or other information about a home in its possession, or that 
it has sold or leased, that likely indicates a noncompliance, defect, 
serious defect, or imminent safety hazard, the retailer must forward the 
complaint or information to the manufacturer of the manufactured home in 
question as early as possible, in accordance with Sec. 3282.256.
    (b) SAA and HUD responsibilities. (1) When an SAA or the Secretary 
receives a consumer complaint or other information that likely indicates 
a noncompliance, defect, serious defect, or imminent safety hazard in a 
manufactured home, the SAA or HUD must:
    (i) Forward the complaint or information to the manufacturer of the 
home in question as early as possible; and
    (ii) Send a copy of the complaint or other information to the SAA of 
the State where the manufactured home was manufactured or to the 
Secretary if there is no such SAA.
    (2) When it appears from the complaint or other information that an 
imminent safety hazard or serious defect may be involved, the SAA of the 
State where the home was manufactured must also send a copy of the 
complaint or other information to the Secretary.
    (c) Manufacturer responsibilities. Whenever the manufacturer 
receives information from any source that the manufacturer believes in 
good faith relates to a noncompliance, defect, serious defect, or 
imminent safety hazard in any of its manufactured homes, the 
manufacturer must, for each such occurrence, make the determinations 
required by Sec. 3282.404.



Sec. 3282.404  Manufacturers' determinations and related concurrences.

    (a) Initial determination. (1) Not later than 30 days after a 
manufacturer receives information that it believes in good faith may 
indicate a noncompliance, defect, serious defect, or imminent safety 
hazard, the manufacturer must make a specific initial determination that 
there is a noncompliance, defect, serious defect, or imminent safety 
hazard, or that the information requires no further action under this 
subpart. If a manufacturer makes a final determination of noncompliance 
for an individual home (see Sec. 3282.412(b)) and a class of homes is 
not involved, no further action is needed by the manufacturer other than 
to keep a record of its determination as required by Sec. 3282.417. If 
the manufacturer determines that it is not the cause of the problem, but 
a problem still exists, the manufacturer must forward the information in 
its possession to the appropriate retailer (see Sec. 3282.254), and, if 
known, to the installer (see Sec. Sec. 3286.115 and 3286.811) for their 
consideration. Alternatively, the manufacturer, retailer, or installer 
may choose to submit the issue for resolution under dispute resolution 
(see 24 CFR part 3288).
    (2) When a manufacturer makes an initial determination that there is 
a serious defect or an imminent safety hazard, the manufacturer must 
immediately notify the Secretary, the SAA in the state of manufacture, 
and the manufacturer's IPIA.
    (3) In making the determination of noncompliance, defect, serious 
defect, or imminent safety hazard, or that no further action is required 
under this subpart, the manufacturer must review the information it 
received and carry out investigations, including, a review of service 
records, IPIA inspection records, and, as appropriate, inspections of 
homes in the class. The manufacturer must review the information, the 
known facts, and the circumstances relating to the complaint or 
information, including service records, approved designs, and audit 
findings, as applicable, to decide what investigations are reasonable.

[[Page 180]]

    (b) Class determination. (1) When the manufacturer makes an initial 
determination of defect, serious defect, or imminent safety hazard, the 
manufacturer must also make a good-faith determination of the class that 
includes each manufactured home in which the same defect, serious 
defect, or imminent safety hazard exists or likely exists. Multiple 
occurrences of defects may be considered the same defect if they have 
the same cause, are related to a specific workstation description, or 
are related to the same failure to follow the manufacturer's approved 
quality assurance manual. Good faith may be used as a defense to the 
imposition of a penalty, but does not relieve the manufacturer of its 
responsibilities for notification or correction under this subpart I. 
The manufacturer must make this class determination not later than 20 
days after making a determination of defect, serious defect, or imminent 
safety hazard.
    (2) Paragraph (c) of this section sets out methods for a 
manufacturer to use in determining the class of manufactured homes. If 
the manufacturer can identify the precise manufactured homes affected by 
the defect, serious defect, or imminent safety hazard, the class of 
manufactured homes may include only those manufactured homes actually 
affected by the same defect, serious defect, or imminent safety hazard. 
The manufacturer is also permitted to exclude from the class those 
manufactured homes for which the manufacturer has information that 
indicates the homes were not affected by the same cause. If it is not 
possible to identify the precise manufactured homes affected, the class 
must include every manufactured home in the group of homes that is 
identifiable, since the same defect, serious defect, or imminent safety 
hazard exists or likely exists in some homes in that group of 
manufactured homes.
    (3) For purposes related to this section, a defect, a serious 
defect, or an imminent safety hazard likely exists in a manufactured 
home if the cause of the defect, serious defect, or imminent safety 
hazard is such that the same defect, serious defect, or imminent safety 
hazard would likely have been introduced systematically into more than 
one manufactured home. Indications that the defect, serious defect, or 
imminent safety hazard would likely have been introduced systematically 
may include, but are not limited to, complaints that can be traced to 
the same faulty design or faulty construction, problems known to exist 
in supplies of components or parts, information related to the 
performance of a particular employee or use of a particular process, and 
information signaling a failure to follow quality control procedures 
with respect to a particular aspect of the manufactured home.
    (4) If the manufacturer must determine the class of homes pursuant 
to paragraph (b) of this section, the manufacturer must obtain from the 
IPIA, and the IPIA must provide, either:
    (i) The IPIA's written concurrence on the methods used by the 
manufacturer to identify the homes that should be included in the class 
of homes; or
    (ii) The IPIA's written statement explaining why it believes the 
manufacturer's methods for determining the class of homes were 
inappropriate or inadequate.
    (c) Methods for determining class. (1) In making a class 
determination under paragraph (b) of this section, a manufacturer is 
responsible for carrying out reasonable investigations. In carrying out 
investigations, the manufacturer must review the information, the known 
facts, and the relevant circumstances, and generally must establish the 
cause of the defect, serious defect, or imminent safety hazard. Based on 
the results of such investigations and all information received or 
developed, the manufacturer must use an appropriate method or 
appropriate methods to determine the class of manufactured homes in 
which the same defect, serious defect, or imminent safety hazard exists 
or likely exists.
    (2) Methods that may be used in determining the class of 
manufactured homes include, but are not limited to:
    (i) Inspection of the manufactured home in question, including its 
design, to determine whether the defect, serious defect, or imminent 
safety hazard resulted from the design itself;
    (ii) Physical inspection of manufactured homes of the same design or 
construction, as appropriate, that were

[[Page 181]]

produced before and after a home in question;
    (iii) Inspection of the service records of a home in question and of 
homes of the same design or construction, as appropriate, produced 
before and after that home, if it is clear that the cause of the defect, 
serious defect, or imminent safety hazard is such that the defect, 
serious defect, or imminent safety hazard would be visible to and 
reportable by consumers or retailers;
    (iv) Inspection of manufacturer quality control records to determine 
whether quality control procedures were followed and, if not, the time 
frame during which they were not;
    (v) Inspection of IPIA records to determine whether the defect, 
serious defect, or imminent safety hazard was either detected or 
specifically found not to exist in some manufactured homes;
    (vi) Identification of the cause as relating to a particular 
employee whose work, or to a process whose use, would have been common 
to the production of the manufacturer's homes for a period of time; and
    (vii) Inspection of records relating to components supplied by other 
parties and known to contain or suspected of containing a defect, a 
serious defect, or an imminent safety hazard.
    (3) When the Secretary or an SAA decides the method chosen by the 
manufacturer to conduct an investigation in order to make a class 
determination is not the most appropriate method, the Secretary or SAA 
must explain in writing to the manufacturer why the chosen method is not 
the most appropriate.
    (d) Documentation required. The manufacturer must comply with the 
recordkeeping requirements in Sec. 3282.417 as applicable to its 
determinations and any IPIA concurrence or statement that it does not 
concur.



Sec. 3282.405  Notification pursuant to manufacturer's determination.

    (a) General requirement. Every manufacturer of manufactured homes 
must provide notification, as set out in this section, with respect to 
any manufactured home produced by the manufacturer in which the 
manufacturer determines, in good faith, that there exists or likely 
exists in more than one home, the same defect introduced systematically, 
a serious defect, or an imminent safety hazard.
    (b) Requirements by category. (1) Noncompliance. A manufacturer must 
provide notification of a noncompliance only when ordered to do so by 
the Secretary or an SAA, pursuant to Sec. Sec. 3282.412 and 3282.413.
    (2) Defects. When a manufacturer has made a class determination in 
accordance with Sec. 3282.404 that a defect exists or likely exists in 
more than one home, the manufacturer must prepare a plan for 
notification in accordance with Sec. 3282.408, and must provide 
notification with respect to each manufactured home in the class of 
manufactured homes.
    (3) Serious defects and imminent safety hazards. When a manufacturer 
has made an initial determination in accordance with Sec. 3282.404(a) 
that a serious defect or imminent safety hazard exists or likely exists, 
the manufacturer must prepare a plan for notification in accordance with 
Sec. 3282.408, must provide notification with respect to all 
manufactured homes in which the serious defect or imminent safety hazard 
exists or likely exists, and must correct the home or homes in 
accordance with Sec. 3282.406.
    (c) Plan for notification required. (1) If a manufacturer determines 
that it is responsible for providing notification under this section, 
the manufacturer must prepare and receive approval on a plan for 
notification as set out in Sec. 3282.408, unless the manufacturer meets 
alternative requirements established in Sec. 3282.407.
    (2) If the Secretary or SAA orders a manufacturer to provide 
notification in accordance with the procedures in Sec. Sec. 3282.412 
and 3282.413, the Secretary or SAA has the option of requiring a 
manufacturer to prepare and receive approval on a plan for notification.
    (d) Method of notification. When a manufacturer provides 
notification as required under this section, notification must be:
    (1) By certified mail or other more expeditious means that provides 
a receipt to each retailer or distributor to whom any manufactured home 
in the class of homes containing the defect,

[[Page 182]]

serious defect, or imminent safety hazard was delivered;
    (2) By certified mail or other more expeditious means that provides 
a receipt to the first purchaser of each manufactured home in the class 
of manufactured homes containing the defect, serious defect, or imminent 
safety hazard, and, to the extent feasible, to any subsequent owner to 
whom any warranty provided by the manufacturer or required by federal, 
state, or local law on such manufactured home has been transferred, 
except that notification need not be sent to any person known by the 
manufacturer not to own the manufactured home in question if the 
manufacturer has a record of a subsequent owner of the manufactured 
home; and
    (3) By certified mail or other more expeditious means that provides 
a receipt to each other person who is a registered owner of a 
manufactured home in the class of homes containing the defect, serious 
defect, or imminent safety hazard and whose name has been ascertained 
pursuant to Sec. 3282.211 or is known to the manufacturer.



Sec. 3282.406  Required manufacturer correction.

    (a) Correction of noncompliances and defects. (1) Section 3282.415 
sets out requirements with respect to a manufacturer's correction of any 
noncompliance or defect that exists in each manufactured home that has 
been sold or otherwise released to a retailer but that has not yet been 
sold to a purchaser.
    (2) In accordance with section 623 of the Act and Part 3288, 
``Manufactured Home Dispute Resolution Program,'' of this chapter, the 
manufacturer, retailer, or installer of a manufactured home deemed 
responsible for correction of repairs or defects must correct, at its 
expense, each failure in the performance, construction, components, or 
material of the home that renders the home or any part of the home not 
fit for the ordinary use for which it was intended and that is reported 
during the one-year period beginning on the date of installation of the 
home (see Sec. 3286.115).
    (b) Correction of serious defects and imminent safety hazards. (1) A 
manufacturer required to furnish notification under Sec. 3282.405 or 
Sec. 3282.413 must correct, at its expense, any serious defect or 
imminent safety hazard that can be related to an error in design or 
assembly of the manufactured home by the manufacturer, including an 
error in design or assembly of any component or system incorporated into 
the manufactured home by the manufacturer.
    (2) If, while making corrections under any of the provisions of this 
subpart, the manufacturer creates an imminent safety hazard or serious 
defect, the manufacturer shall correct the imminent safety hazard or 
serious defect.
    (3) Each serious defect or imminent safety hazard corrected under 
this paragraph (b) must be brought into compliance with applicable 
construction and safety standards or, where those standards are not 
specific, with the manufacturer's approved design.
    (c) Inclusion in plan. (1) In the plan required by Sec. 3282.408, 
the manufacturer must provide for correction of those homes that are 
required to be corrected pursuant to paragraph (b) of this section.
    (2) If the Secretary or SAA orders a manufacturer to provide 
correction in accordance with the procedures in Sec. 3282.413, the 
Secretary or SAA has the option of requiring a manufacturer to prepare 
and receive approval on a plan for correction.
    (d) Corrections by owners. A manufacturer that is required to make 
corrections under paragraph (b) of this section, or that elects to make 
corrections in accordance with Sec. 3282.407, must reimburse any owner 
of an affected manufactured home who choses to make the correction 
before the manufacturer did so, for the reasonable cost of correction.
    (e) Correction of appliances, components, or systems. (1) If any 
appliance, component, or system in a manufactured home is covered by a 
product warranty, the manufacturer, retailer, or installer that is 
responsible under this section for correcting a noncompliance, defect, 
serious defect, or imminent safety hazard in the appliance, component, 
or system may seek the required correction directly from the producer. 
The SAA that approves

[[Page 183]]

any plan of notification required pursuant to Sec. 3282.408 or the 
Secretary, as applicable, may establish reasonable time limits for the 
manufacturer of the home and the producer of the appliance, component, 
or system to agree on who is to make the correction and for completing 
the correction.
    (2) Nothing in this section shall prevent the manufacturer, 
retailer, or installer from seeking indemnification from the producer of 
the appliance, component, or system for correction work done on any 
appliance, component, or system.



Sec. 3282.407  Voluntary compliance with the notification and
correction requirements under the Act.

    A manufacturer that takes corrective action that complies with one 
of the following three alternatives to the requirement in Sec. 3282.408 
for preparing a plan will be deemed to have provided any notification 
required by Sec. 3282.405:
    (a) Voluntary action--one home. When a manufacturer has made a 
determination that only one manufactured home is involved, the 
manufacturer is not required to provide notification pursuant to Sec. 
3282.405 or to prepare or submit a plan if:
    (1) The manufacturer has made a determination of defect; or
    (2) The manufacturer has made a determination of serious defect or 
imminent safety hazard and corrects the home within the 20-day period. 
The manufacturer must maintain, in the plant where the manufactured home 
was manufactured, a complete record of the correction. The record must 
describe briefly the facts of the case and any known cause of the 
serious defect or imminent safety hazard, state what corrective actions 
were taken, and be maintained in the service records in a form that will 
allow the Secretary or an SAA to review all such corrections.
    (b) Voluntary action--multiple homes. Regardless of whether a plan 
has been submitted under Sec. 3282.408, the manufacturer may act prior 
to obtaining approval of the plan. Such action is subject to review and 
disapproval by the SAA of the state where the home was manufactured or 
by the Secretary, unless the manufacturer obtains the written agreement 
of the SAA or the Secretary that the corrective action is adequate. If 
such an agreement is obtained, the correction must be accepted as 
adequate by all SAAs and the Secretary, if the manufacturer makes the 
correction as agreed to and any imminent safety hazard or serious defect 
is eliminated.
    (c) Waiver. (1) A manufacturer may obtain a waiver of the 
notification requirements in Sec. 3282.405 and the plan requirements in 
Sec. 3282.408 either from the SAA of the state of manufacture, when all 
of the manufactured homes that would be covered by the plan were 
manufactured in that state, or from the Secretary. As of the date of a 
request for a waiver, the notification and plan requirements are 
deferred pending timely submission of any additional documentation as 
the SAA or the Secretary may require and final resolution of the waiver 
request. If a waiver request is not granted, the plan required by Sec. 
3282.408 must be submitted within 5 days after the expiration of the 
time frame established in Sec. 3282.408, if the manufacturer is 
notified that the request was not granted.
    (2) The waiver may be approved if, not later than 20 days after 
making the determination that notification is required, the manufacturer 
presents evidence that it, in good faith, believes would show to the 
satisfaction of the SAA or the Secretary that:
    (i) The manufacturer has identified all homes that would be covered 
by the plan in accordance with Sec. 3282.408;
    (ii) The manufacturer will correct, at its expense, all of the 
identified homes, either within 60 days of being informed that the 
request for waiver has been granted or within another time limit 
approved in the waiver;
    (iii) The proposed repairs are adequate to remove the defect, 
serious defect, or imminent safety hazard that gave rise to the 
determination that correction is required; and
    (3) The manufacturer must correct all affected manufactured homes 
within 60 days of being informed that the request for waiver has been 
granted or within the time limit approved in the waiver, as applicable. 
The manufacturer must record the known cause of the problem and the 
correction in the service records, in an approved form

[[Page 184]]

that will allow the Secretary or SAA to review the cause and correction.



Sec. 3282.408  Plan of notification required.

    (a) Manufacturer's plan required. Except as provided in Sec. 
3282.407, if a manufacturer determines that it is responsible for 
providing notification under Sec. 3282.405, the manufacturer must 
prepare a plan in accordance with this section and Sec. 3282.409. The 
manufacturer must, as soon as practical, but not later than 20 days 
after making the determination of defect, serious defect, or imminent 
safety hazard, submit the plan for approval to one of the following, as 
appropriate:
    (1) The SAA of the State of manufacture, when all of the 
manufactured homes covered by the plan were manufactured in that State; 
or
    (2) The Secretary, when the manufactured homes were manufactured in 
more than one State or there is no SAA in the State of manufacture.
    (b) Implementation of plan. Upon approval of the plan, including any 
changes for cause required by the Secretary or SAA after consultation 
with the manufacturer, the manufacturer must carry out the approved plan 
within the agreed time limits.



Sec. 3282.409  Contents of plan.

    (a) Purpose of plan. This section sets out the requirements that 
must be met by a manufacturer in preparing any plan it is required to 
submit under Sec. 3282.408. The underlying requirement is that the plan 
show how the manufacturer will fulfill its responsibilities with respect 
to notification and correction.
    (b) Contents of plan. The plan must:
    (1) Identify, by serial number and other appropriate identifying 
criteria, all manufactured homes for which notification is to be 
provided, as determined pursuant to Sec. 3282.404;
    (2) Include a copy of the notice that the manufacturer proposes to 
use to provide the notification required by Sec. 3282.405;
    (3) Provide for correction of those manufactured homes that are 
required to be corrected pursuant to Sec. 3282.406(b);
    (4) Include the IPIA's written concurrence or statement on the 
methods used by the manufacturer to identify the homes that should be 
included in the class of homes, as required pursuant to Sec. 
3282.404(b); and
    (5) Include a deadline for completion of all notifications and 
corrections.
    (c) Contents of notice. Except as otherwise agreed by the Secretary 
or the SAA reviewing the plan under Sec. 3282.408, the notice to be 
approved as part of the plan must include the following:
    (1) An opening statement that reads: ``This notice is sent to you in 
accordance with the requirements of the National Manufactured Housing 
Construction and Safety Standards Act.''
    (2) The following statement: ``[choose one, as appropriate: 
Manufacturer's name, or the Secretary, or the (insert State) SAA] has 
determined that [insert identifying criteria of manufactured home] may 
not comply with an applicable Federal Manufactured Home Construction or 
Safety Standard.''
    (3) Except when the manufacturer is providing notice pursuant to an 
approved plan or agreement with the Secretary or an SAA under Sec. 
3282.408, each applicable statement must read as follows:
    (i) ``An imminent safety hazard may exist in (identifying criteria 
of manufactured home).''
    (ii) ``A serious defect may exist in (identifying criteria of 
manufactured home).''
    (iii) ``A defect may exist in (identifying criteria of manufactured 
home).''
    (4) A clear description of the defect, serious defect, or imminent 
safety hazard and an explanation of the risk to the occupants, which 
must include:
    (i) The location of the defect, serious defect, or imminent safety 
hazard in the manufactured home;
    (ii) A description of any hazards, malfunctions, deterioration, or 
other consequences that may reasonably be expected to result from the 
defect, serious defect, or imminent safety hazard;
    (iii) A statement of the conditions that may cause such consequences 
to arise; and
    (iv) Precautions, if any, that the owner can, should, or must take 
to reduce the chance that the consequences will arise before the 
manufactured home is repaired;

[[Page 185]]

    (5) A statement of whether there will be any warning that a 
dangerous occurrence may take place and what that warning would be, and 
of any signs that the owner might see, hear, smell, or feel that might 
indicate danger or deterioration of the manufactured home as a result of 
the defect, serious defect, or imminent safety hazard;
    (6) A statement that the manufacturer will correct the manufactured 
home, if the manufacturer will correct the manufactured home under this 
subpart or otherwise;
    (7) A statement in accordance with whichever of the following is 
appropriate:
    (i) Where the manufacturer will correct the manufactured home at no 
cost to the owner, the statement must indicate how and when the 
correction will be done, how long the correction will take, and any 
other information that may be helpful to the owner; or
    (ii) When the manufacturer does not bear the cost of repair, the 
notification must include a detailed description of all parts and 
materials needed to make the correction; a description of all steps to 
be followed in making the correction, including appropriate 
illustrations; and an estimate of the cost of the purchaser or owner of 
the correction;
    (8) A statement informing the owner that the owner may submit a 
complaint to the SAA or Secretary if the owner believes that:
    (i) The notification or the remedy described therein is inadequate;
    (ii) The manufacturer has failed or is unable to remedy the problem 
in accordance with its notification; or
    (iii) The manufacturer has failed or is unable to remedy the problem 
within a reasonable time after the owner's first attempt to obtain 
remedy; and
    (9) A statement that any actions taken by the manufacturer under the 
Act in no way limit the rights of the owner or any other person under 
any contract or other applicable law and that the owner may have further 
rights under contract or other applicable law.



Sec. 3282.410  Implementation of plan.

    (a) Deadline for notifications. (1) The manufacturer must complete 
the notifications carried out under a plan approved by an SAA or the 
Secretary under Sec. 3282.408 on or before the deadline approved by the 
SAA or Secretary. In approving each deadline, an SAA or the Secretary 
will allow a reasonable time to complete all notifications, taking into 
account the number of manufactured homes involved and the difficulty of 
completing the notifications.
    (2) The manufacturer must, at the time of dispatch, furnish to the 
SAA or the Secretary a true or representative copy of each notice, 
bulletin, and other written communication sent to retailers, 
distributors, or owners of manufactured homes regarding any serious 
defect or imminent safety hazard that may exist in any homes produced by 
the manufacturer, or regarding any noncompliance or defect for which the 
SAA or Secretary requires, under Sec. 3282.413(c), the manufacturer to 
submit a plan for providing notification.
    (b) Deadline for corrections. A manufacturer that is required to 
correct a serious defect or imminent safety hazard pursuant to Sec. 
3282.406(b) must complete implementation of the plan required by Sec. 
3282.408 on or before the deadline approved by the SAA or the Secretary. 
The deadline must be no later than 60 days after approval of the plan. 
In approving the deadline, the SAA or the Secretary will allow a 
reasonable amount of time to complete the plan, taking into account the 
seriousness of the problem, the number of manufactured homes involved, 
the immediacy of any risk, and the difficulty of completing the action. 
The seriousness and immediacy of any risk posed by the serious defect or 
imminent safety hazard will be given greater weight than other 
considerations.
    (c) Extensions. An SAA that approved a plan or the Secretary may 
grant an extension of the deadlines included in a plan, if the 
manufacturer requests such an extension in writing and shows good cause 
for the extension, if the SAA or the Secretary decides that the 
extension is justified and not contrary to the public interest. When the 
Secretary grants an extension for completion of any corrections, the 
Secretary will notify the manufacturer and must publish notice of such 
extension in the Federal Register. When an SAA grants an extension for 
completion of

[[Page 186]]

any corrections, the SAA must notify the Secretary and the manufacturer.
    (d) Recordkeeping. The manufacturer must provide the report and 
maintain the records that are required by Sec. 3282.417 for all 
notification and correction actions.



Sec. 3282.411  SAA initiation of remedial action.

    (a) SAA review of information. Whenever an SAA has information 
indicating the possible existence of a noncompliance, defect, serious 
defect, or imminent safety hazard in a manufactured home, the SAA may 
initiate administrative review of the need for notification and 
correction. An SAA initiates administrative review by either:
    (1) Referring the matter to another SAA in accordance with paragraph 
(b) of this section or to the Secretary; or
    (2) Taking action itself, in accordance with Sec. 3282.412, when it 
appears that all of the homes affected by the noncompliance, defect, 
serious defect, or imminent safety hazard were manufactured in the SAA's 
State.
    (b) SAA referral of matter. If at any time it appears that the 
affected manufactured homes were manufactured in more than one State, an 
SAA that decides to initiate such administrative review must refer the 
matter to the Secretary for possible action pursuant to Sec. 3282.412. 
If it appears that all of the affected manufactured homes were 
manufactured in another State, an SAA that decides to initiate 
administrative review must refer the matter to the SAA in the State of 
manufacture or to the Secretary, for possible action pursuant to Sec. 
3282.412.



Sec. 3282.412  Preliminary and final administrative determinations.

    (a) Grounds for issuance of preliminary determination. The Secretary 
or, in accordance with Sec. 3282.411, an SAA in the State of 
manufacture, may issue a Notice of Preliminary Determination when:
    (1) The manufacturer has not provided to the Secretary or SAA the 
necessary information to make a determination that:
    (i) A noncompliance, defect, serious defect, or imminent safety 
hazard possibly exists; or
    (ii) A manufacturer had information that likely indicates a 
noncompliance, defect, serious defect, or imminent safety hazard for 
which the manufacturer failed to make the determinations required under 
Sec. 3282.404;
    (2) The Secretary or SAA has information that indicates a 
noncompliance, defect, serious defect, or imminent safety hazard 
possibly exists, and, in the case of the SAA, the SAA believes that:
    (i) The affected manufactured home has been sold or otherwise 
released by a manufacturer to a retailer or distributor, but there is no 
completed sale of the home to a purchaser;
    (ii) Based on the same factors that are established for a 
manufacturer's class determination in Sec. 3282.404(b), the information 
indicates a class of homes in which a noncompliance or defect possibly 
exists; or
    (iii) The information indicates one or more homes in which a serious 
defect or an imminent safety hazard possibly exists;
    (3) The Secretary or SAA is reviewing a plan under Sec. 3282.408 
and the Secretary or SAA disagree with the manufacturer on proposed 
changes to the plan;
    (4) The Secretary or SAA believes that the manufacturer has failed 
to fulfill the requirements of a waiver granted under Sec. 3282.407(c); 
or
    (5) There is information that a manufacturer failed to make the 
determinations required under Sec. 3282.404.
    (b) Additional requirements--SAA issuance. (1) An SAA that receives 
information that indicates a serious defect or an imminent safety hazard 
possibly exists in a home manufactured in that SAA's State must notify 
the Secretary about that information.
    (2) An SAA that issues a preliminary determination must provide a 
copy of the preliminary determination to the Secretary at the time of 
its issuance. Failure to comply with this requirement does not affect 
the validity of the preliminary determination.
    (c) Additional requirements--Secretary issuance. The Secretary will 
notify the SAA of each State where the affected homes were manufactured, 
and, to the extent reasonable, the SAA of each State where the homes are 
located, of

[[Page 187]]

the issuance of a preliminary determination. Failure to comply with this 
requirement does not affect the validity of the preliminary 
determination.
    (d) Notice of Preliminary Determination. (1) The Notice of 
Preliminary Determination must be sent by certified mail or express 
delivery and must:
    (i) Include the factual basis for the determination;
    (ii) Include the criteria used to identify any class of homes in 
which the noncompliance, defect, serious defect, or imminent safety 
hazard possibly exists;
    (iii) If applicable, indicate that the manufacturer may be required 
to make corrections on a home or in a class of homes; and
    (iv) If the preliminary determination is that the manufacturer 
failed to make an initial determination required under Sec. 
3282.404(a), include an allegation that the manufacturer failed to act 
in good faith.
    (2) The Notice of Preliminary Determination must inform the 
manufacturer that the preliminary determination will become final unless 
the manufacturer requests a hearing or presentation of views under 
subpart D of this part.
    (e) Presentation of views. (1) If a manufacturer elects to exercise 
its right to a hearing or presentation of views, the Secretary or the 
SAA, as applicable, must receive the manufacturer's request for a 
hearing or presentation of views:
    (i) Within 15 days of delivery of the Notice of Preliminary 
Determination of serious defect, defect, or noncompliance; or
    (ii) Within 5 days of delivery of the Notice of Preliminary 
Determination of imminent safety hazard.
    (2) A Formal or an Informal Presentation of Views will be held in 
accordance with Sec. 3282.152 promptly upon receipt of a manufacturer's 
request under paragraph (c) of this section.
    (f) Issuance of Final Determination. (1) The SAA or the Secretary, 
as appropriate, may make a Final Determination that is based on the 
allegations in the preliminary determination and adverse to the 
manufacturer if:
    (i) The manufacturer fails to respond to the Notice of Preliminary 
Determination within the time period established in paragraph (c)(2) of 
this section; or
    (ii) The SAA or the Secretary decides that the views and evidence 
presented by the manufacturer or others are insufficient to rebut the 
preliminary determination.
    (2) At the time that the SAA or Secretary makes a Final 
Determination that an imminent safety hazard, serious defect, defect, or 
noncompliance exists, the SAA or Secretary, as appropriate, must issue 
an order in accordance with Sec. 3282.413.



Sec. 3282.413  Implementation of Final Determination.

    (a) Issuance of orders. (1) The SAA or the Secretary, as 
appropriate, must issue an order directing the manufacturer to furnish 
notification if:
    (i) The SAA makes a Final Determination that a defect or 
noncompliance exists in a class of homes;
    (ii) The Secretary makes a Final Determination that an imminent 
safety hazard, serious defect, defect, or noncompliance exists; or
    (iii) The SAA makes a Final Determination that an imminent safety 
hazard or a serious defect exists in any home, and the SAA has received 
the Secretary's concurrence on the issuance of the Final Determination 
and order.
    (2) The SAA or the Secretary, as appropriate, must issue an order 
directing the manufacturer to make corrections in any affected 
manufactured home if:
    (i) The SAA or the Secretary makes a Final Determination that a 
defect or noncompliance exists in a manufactured home that has been sold 
or otherwise released by a manufacturer to a retailer or distributor but 
for which the sale to a purchaser has not been completed;
    (ii) The Secretary makes a Final Determination that an imminent 
safety hazard or serious defect exists; or
    (iii) The SAA makes a Final Determination that an imminent safety 
hazard or serious defect exists in any home, and the SAA has received 
the Secretary's concurrence on the issuance of the Final Determination 
and order.

[[Page 188]]

    (3) Only the Secretary may issue an order directing a manufacturer 
to repurchase or replace any manufactured home already sold to a 
purchaser, unless the Secretary authorizes an SAA to issue such an 
order.
    (4) An SAA that has a concurrence or authorization from the 
Secretary on any order issued under this section must have the 
Secretary's concurrence on any subsequent changes to the order. An SAA 
that has issued a Preliminary Determination must have the Secretary's 
concurrence on any waiver of notification or any settlement when the 
concerns addressed in the Preliminary Determination involve a serious 
defect or an imminent safety hazard.
    (5) If an SAA or the Secretary makes a Final Determination that the 
manufacturer failed to make, in good faith, an initial determination 
required under Sec. 3282.404(a):
    (i) The SAA may impose any penalties or take any action applicable 
under State law and may refer the matter to the Secretary for 
appropriate action; and
    (ii) The Secretary may take any action permitted by law.
    (b) Decision to order replacement or repurchase. The SAA or the 
Secretary will order correction of any manufactured home covered by an 
order issued in accordance with paragraph (a)(2) of this section, unless 
any requirements and factors applicable under Sec. 3282.414 and Sec. 
3282.415 indicate that the SAA or the Secretary should order replacement 
or repurchase of the home.
    (c) Time for compliance with order. (1) The SAA or the Secretary may 
require the manufacturer to submit a plan for providing any notification 
and any correction, replacement, or repurchase remedy that results from 
an order under this section. The manufacturer's plan must include the 
method and date by which notification and any corrective action will be 
provided.
    (2) The manufacturer must provide any such notification and 
correction, replacement, or repurchase remedy as early as practicable, 
but not later than:
    (i) Thirty days after issuance of the order, in the case of a Final 
Determination of imminent safety hazard or when the SAA or Secretary has 
ordered replacement or repurchase of a home pursuant to Sec. 3282.414; 
or
    (ii) Sixty days after issuance of the order, in the case of a Final 
Determination of serious defect, defect, or noncompliance.
    (3) Subject to the requirements of paragraph (a)(3) of this section, 
the SAA that issued the order or the Secretary may grant an extension of 
the deadline for compliance with an order if:
    (i) The manufacturer requests such an extension in writing and shows 
good cause for the extension; and
    (ii) The SAA or the Secretary is satisfied that the extension is 
justified in the public interest.
    (4) When the SAA grants an extension, it must notify the 
manufacturer and forward to the Secretary a draft of a notice of the 
extension for the Secretary to publish in the Federal Register. When the 
Secretary grants an extension, the Secretary must notify the 
manufacturer and publish notice of such extension in the Federal 
Register.
    (d) Appeal of SAA determination. Within 10 days of a manufacturer 
receiving notice that an SAA has made a Final Determination that an 
imminent safety hazard, a serious defect, a defect, or noncompliance 
exists or that the manufacturer failed to make the determinations 
required under Sec. 3282.404, the manufacturer may appeal the Final 
Determination to the Secretary under Sec. 3282.309.
    (e) Settlement offers. A manufacturer may propose in writing, at any 
time, an offer of settlement and shall submit it for consideration by 
the Secretary or the SAA that issued the Notice of Preliminary 
Determination. The Secretary or the SAA has the option of providing the 
manufacturer making the offer with an opportunity to make an oral 
presentation in support of such offer. If the manufacturer is notified 
that an offer of settlement is rejected, the offer is deemed to have 
been withdrawn and will not constitute a part of the record in the 
proceeding. Final acceptance by the Secretary or an SAA of any offer of 
settlement automatically terminates any proceedings related to the 
matter involved in the settlement.

[[Page 189]]

    (f) Waiver of notification. (1) At any time after the Secretary or 
an SAA has issued a Notice of Preliminary Determination, the 
manufacturer may ask the Secretary or SAA to waive any formal 
notification requirements. When requesting a waiver, the manufacturer 
must certify that:
    (i) The manufacturer has made a class determination in accordance 
with Sec. 3282.404(b);
    (ii) The manufacturer will correct, at the manufacturer's expense, 
all affected manufactured homes in the class within a time period 
specified by the Secretary or SAA, but not later than 60 days after the 
manufacturer is notified of the acceptance of the request for waiver or 
the issuance of any Final Determination, whichever is later; and
    (iii) The proposed repairs are adequate to correct the 
noncompliance, defect, serious defect, or imminent safety hazard that 
gave rise to the issuance of the Notice of Preliminary Determination.
    (2) If the Secretary or SAA grants a waiver, the manufacturer must 
reimburse any owner of an affected manufactured home who chose to make 
the correction before the manufacturer did so, for the reasonable cost 
of correction.
    (g) Recordkeeping. The manufacturer must provide the report and 
maintain the records that are required by Sec. 3282.417 for all 
notification and correction actions.



Sec. 3282.414  Replacement or repurchase of homes after sale to purchaser.

    (a) Order to replace or repurchase. Whenever a manufacturer cannot 
correct or remove an imminent safety hazard or a serious defect in a 
manufactured home, for which there is a completed sale to a purchaser, 
within 60 days of the issuance of an order under Sec. 3282.413 or any 
extension of the 60-day deadline that has been granted by the Secretary 
in accordance with Sec. 3282.413(c)(3), the Secretary or, if authorized 
in writing by the Secretary in accordance with Sec. 3282.413(a)(3), the 
SAA may require that the manufacturer:
    (1) Replace the manufactured home with a home that:
    (i) Is substantially equal in size, equipment, and quality; and
    (ii) Either is new or is in the same condition that the defective 
manufactured home would have been in at the time of discovery of the 
imminent safety hazard or serious defect had the imminent safety hazard 
or serious defect not existed; or
    (2) Take possession of the manufactured home, if the Secretary or 
the SAA so orders, and refund the purchase price in full, except that 
the amount of the purchase price may be reduced by a reasonable amount 
for depreciation if the home has been in the possession of the owner for 
more than one year and the amount of depreciation is based on:
    (i) Actual use of the home; and
    (ii) An appraisal system approved by the Secretary or the SAA that 
does not take into account damage or deterioration resulting from the 
imminent safety hazard or serious defect.
    (b) Factors affecting order. In determining whether to order 
replacement or refund by the manufacturer, the Secretary or the SAA will 
consider:
    (1) The threat of injury or death to manufactured home occupants;
    (2) Any costs and inconvenience to manufactured-home owners that 
will result from the lack of adequate repair within the specified 
period;
    (3) The expense to the manufacturer;
    (4) Any obligations imposed on the manufacturer under contract, or 
other applicable law of which the Secretary or the SAA has knowledge; 
and
    (5) Any other relevant factors that may be brought to the attention 
of the Secretary or the SAA.
    (c) Owner's election of remedy. When under contract or other 
applicable law the owner has the right of election between replacement 
and refund, the manufacturer must inform the owner of such right of 
election and must inform the Secretary of the election, if any, made by 
the owner.
    (d) Recordkeeping. The manufacturer must provide the report that is 
required by Sec. 3282.417 when a manufactured home has been replaced or 
repurchased under this section.

[[Page 190]]



Sec. 3282.415  Correction of homes before sale to purchaser.

    (a) Sale or lease prohibited. Manufacturers, retailers, and 
distributors must not sell, lease, or offer for sale or lease any 
manufactured home that they have reason to know, in the exercise of due 
care, contains a noncompliance, defect, serious defect, or imminent 
safety hazard. The sale of a home to a purchaser is complete when all 
contractual obligations of the manufacturer, retailer, and distributor 
to the purchaser and conditions specified in Sec. 3282.252 have been 
met.
    (b) Retailer/distributor notification to manufacturer. When a 
retailer, acting as a reasonable retailer, or a distributor, acting as a 
reasonable distributor, believes that a manufactured home that has been 
sold to the retailer or distributor, but for which there is no completed 
sale to a purchaser, likely contains a noncompliance, defect, serious 
defect, or imminent safety hazard, the retailer or distributor must 
notify the manufacturer of the home in a timely manner.
    (c) Manufacturer's remedial responsibilities. Upon a Final 
Determination pursuant to Sec. 3282.412(f) by the Secretary or an SAA, 
a determination by a court of appropriate jurisdiction, or a 
manufacturer's own determination that a manufactured home that has been 
sold to a retailer but for which there is no completed sale to a 
purchaser contains a noncompliance, defect, serious defect, or imminent 
safety hazard, the manufacturer must do one of the following:
    (1) Immediately repurchase such manufactured home from the retailer 
or distributor at the price paid by the retailer or distributor, plus 
pay all transportation charges involved, if any, and a reasonable 
reimbursement of not less than one percent per month of such price paid, 
prorated from the date the manufacturer receives notice by certified 
mail of the noncompliance, defect, serious defect, or imminent safety 
hazard; or
    (2) At its expense, immediately furnish to the retailer or 
distributor all required parts or equipment for installation in the home 
by the retailer or distributor, and the manufacturer must reimburse the 
retailer or distributor for the reasonable value of the retailer's or 
distributor's work, plus a reasonable reimbursement of not less than one 
percent per month of the manufacturer's or distributor's selling price, 
prorated from the date the manufacturer receives notice by certified 
mail to the date the noncompliance, defect, serious defect, or imminent 
safety hazard is corrected, so long as the retailer or distributor 
proceeds with reasonable diligence with the required work; or
    (3) Carry out all needed corrections to the home.
    (d) Establishing costs. The value of reasonable reimbursements as 
specified in paragraph (c) of this section will be fixed by either:
    (1) Mutual agreement of the manufacturer and retailer or 
distributor; or
    (2) A court in an action brought under section 613(b) of the Act (42 
U.S.C. 5412(b)).
    (e) Records required. The manufacturer and the retailer or 
distributor must maintain records of their actions taken under this 
section in accordance with Sec. 3282.417.
    (f) Exception for leased homes. This section does not apply to any 
manufactured home purchased by a retailer or distributor that has been 
leased by such retailer or distributor to a tenant for purposes other 
than resale. Other remedies that may be available to a retailer or 
distributor under subpart I of this part continue to be applicable.
    (g) Indemnification. A manufacturer may indemnify itself through 
agreements or contracts with retailers, distributors, transporters, 
installers, or others for the costs of repurchase, parts, equipment, and 
corrective work incurred by the manufacturer pursuant to paragraph (c).



Sec. 3282.416  Oversight of notification and correction activities.

    (a) IPIA responsibilities. The IPIA in each manufacturing plant 
must:
    (1) Assure that notifications required under this subpart I are sent 
to all owners, purchasers, retailers, and distributors of whom the 
manufacturer has knowledge;
    (2) Audit the certificates required by Sec. 3282.417 to assure that 
the manufacturer has made required corrections;

[[Page 191]]

    (3) Whenever a manufacturer is required to determine a class of 
homes pursuant to Sec. 3282.404(b), provide either:
    (i) The IPIA's written concurrence on the methods used by the 
manufacturer to identify the homes that should be included in the class 
of homes; or
    (ii) The IPIA's written statement explaining why it believes the 
manufacturer's methods for determining the class of homes were 
inappropriate or inadequate; and
    (4) Conduct, at least monthly, a review the manufacturer's service 
records of determinations under Sec. 3282.404 and take appropriate 
action in accordance with Sec. Sec. 3282.362(c) and 3282.364.
    (b) SAA and Secretary's responsibilities. (1) SAA oversight of 
manufacturer compliance with this subpart will be done primarily by 
periodically checking the records that manufacturers are required to 
keep under Sec. 3282.417.
    (2) The SAA or Secretary to which the report required by Sec. 
3282.417(a) is sent is responsible for assuring, through oversight, that 
remedial actions have been carried out as described in the report. The 
SAA of the State in which an affected manufactured home is located may 
inspect that home to determine whether any correction required under 
this subpart I is carried out in accordance with the approved plan or, 
if there is no plan, with the construction and safety standards or other 
approval obtained by the manufacturer.



Sec. 3282.417  Recordkeeping requirements.

    (a) Manufacturer report on notifications and corrections. Within 30 
days after the deadline for completing any notifications, corrections, 
replacement, or repurchase required pursuant to this subpart, the 
manufacturer must provide a complete report of the action taken to, as 
appropriate, the Secretary or the SAA that approved the plan under Sec. 
3282.408, granted a waiver, or issued the order under Sec. 3282.413. If 
any other SAA or the Secretary forwarded the relevant consumer complaint 
or other information to the manufacturer in accordance with Sec. 
3282.403, the manufacturer must send a copy of the report to that SAA or 
the Secretary, as applicable.
    (b) Records of manufacturer's determinations. (1) A manufacturer 
must record each initial and class determination required under Sec. 
3282.404, in a manner approved by the Secretary or an SAA and that 
identifies who made each determination, what each determination was, and 
all bases for each determination. Such information must be available for 
review by the IPIA.
    (2) The manufacturer records must include:
    (i) The information it received that likely indicated a 
noncompliance, defect, serious defect, or imminent safety hazard;
    (ii) All of the manufacturer's determinations and each basis for 
those determinations;
    (iii) The methods used by the manufacturer to establish any class, 
including, when applicable, the cause of the defect, serious defect, or 
imminent safety hazard; and
    (iv) Any IPIA concurrence or statement that it does not concur with 
the manufacturer's class determination, in accordance with Sec. 
3282.404(b).
    (3) When the records that a manufacturer is required to keep in 
accordance with this paragraph (b) involve a class of manufactured homes 
that have the same noncompliance, defect, serious defect, or imminent 
safety hazard, the manufacturer has the option of meeting the 
requirements of this paragraph by establishing a class determination 
file, instead of including the same information in the file required by 
paragraph (e) of this section for each affected home. Such class 
determination file must contain the records of each class determination, 
notification, and correction, as applicable. For each class 
determination, the manufacturer must record once in each class 
determination file the information common to the class, and must 
identify by serial number all of the homes that the class comprises and 
that are subject to notification and correction, as applicable.
    (c) Manufacturer records of notifications. When a manufacturer is 
required to provide notification under this subpart, the manufacturer 
must maintain a record of each type of notice sent and

[[Page 192]]

a complete list of the persons notified and their addresses. The 
manufacturer must maintain these records in a manner approved by the 
Secretary or an SAA to identify each notification campaign.
    (d) Manufacturer records of corrections. When a manufacturer is 
required to provide or provides correction under this subpart, the 
manufacturer must maintain a record of one of the following, as 
appropriate, for each manufactured home involved:
    (1) If the correction is made, a certification by the manufacturer 
that the repair was made to conform to the federal construction and 
safety standards in effect at the time the home was manufactured and 
that each identified imminent safety hazard or serious defect has been 
corrected; or
    (2) If the owner refuses to allow the manufacturer to repair the 
home, a certification by the manufacturer that:
    (i) The owner has been informed of the problem that may exist in the 
home;
    (ii) The owner has been provided with a description of any hazards, 
malfunctions, deterioration, or other consequences that may reasonably 
be expected to result from the defect, serious defect, or imminent 
safety hazard; and
    (iii) An attempt has been made to repair the problems, but the owner 
has refused the repair.
    (e) Maintenance of manufacturer's records. (1) Except as provided in 
paragraph (b)(3) of this section, for each manufactured home produced by 
a manufacturer, the manufacturer must maintain in a printed or 
electronic format all of the information required by paragraphs (b), 
(c), and (d) of this section, and must consolidate the information in a 
readily accessible file or in a readily accessible combination of a 
printed file and an electronic file. For each home, the manufacturer 
also must include in such file a copy of the homes data plate; all 
information related to manufacture, handling, and assembly of the home; 
any checklist or similar documentation used by the manufacturer in the 
transport of the home; the name and address of the retailer; the 
original or a copy of each purchaser's registration record received by 
the manufacturer; all correspondence with the retailer and homeowner 
that is related to the home; any information received by the 
manufacturer regarding setup of the home; all work orders for servicing 
the home; and the information that the manufacturer is required to keep 
pursuant to Sec. 3282.211. The manufacturer must organize all such 
files in order of the serial numbers of the homes produced.
    (2) The manufacturer must maintain each of these manufactured-home 
records at the plant where the home was produced. If that plant is no 
longer in existence, the manufacturer must keep the records at its 
nearest production plant in the same State, or, if such a plant does not 
exist, at the manufacturer's corporate headquarters.



Sec. 3282.418  Factors for appropriateness and amount of civil penalties.

    In determining whether to seek a civil penalty for a violation of 
the requirements of this subpart, and the amount of such penalty to be 
recommended, the Secretary will consider the provisions of the Act and 
the following factors:
    (a) The gravity of the violation;
    (b) The degree of the violator's culpability, including whether the 
violator had acted in good faith in trying to comply with the 
requirements;
    (c) The injury to the public;
    (d) Any injury to owners or occupants of manufactured homes
    (e) The ability to pay the penalty;
    (f) Any benefits received by the violator;
    (g) The extent of potential benefits to other persons;
    (h) Any history of prior violations;
    (i) Deterrence of future violations; and
    (j) Such other factors as justice may require.



           Subpart J_Monitoring of Primary Inspection Agencies



Sec. 3282.451  General.

    The actions of all primary inspection agencies accepted under 
subpart H shall be monitored by the Secretary or the Secretary's agent 
to determine whether the PIAs are fulfilling their

[[Page 193]]

responsibilities under these regulations. This monitoring shall be 
carried out primarily through joint monitoring teams made up of 
personnel supplied by SAAs and by the Secretary or the Secretary's 
agent. Monitoring parties shall make recommendations to the Secretary 
with respect to final acceptance of PIAs under Sec. Sec. 3282.361(e) 
and 3282.362(e), continued acceptance, and disqualification or 
requalification under Sec. 3282.356, and with respect to any changes 
which PIAs should make in their operations in order to continue to be 
approved. Based on this monitoring, the Secretary shall determine 
whether PIAs should continue to be approved under these regulations.



Sec. 3282.452  Participation in monitoring.

    (a) Joint monitoring teams. (1) The Secretary or the Secretary's 
agent shall develop and coordinate joint monitoring teams which shall be 
made up of qualified personnel provided by SAAs and by the Secretary or 
the Secretary's agent. The Secretary or the Secretary's agent shall 
determine whether personnel are qualified based on education or 
experience.
    (2) The joint monitoring teams will operate generally on a regional 
basis. To the extent possible, the teams shall be so scheduled that 
personnel provided by an SAA will be monitoring operations in 
manufactured home plants from which manufactured homes are shipped into 
their State.
    (3) Personnel from an SAA shall not participate on joint monitoring 
teams operating within their State.
    (4) States are encouraged but not required to participate on joint 
monitoring teams.
    (b) State monitoring. A State may carry out monitoring of IPIA 
functions at plant facilities within the State if the State is not 
acting as an IPIA. Where a State wishes to carry out monitoring 
activities it shall do so in coordination with the Secretary and the 
Secretary's agent. To the extent that the State is performing adequate 
monitoring, the frequency of the joint team monitoring may be reduced to 
one visit per year consistent with the requirements of Sec. 3282.453.
    (c) Review of staff capability. The monitoring party shall review 
the capability of the PIA's staff to perform the functions it is 
required to perform.
    (d) Review of interpretations. The monitoring party shall review all 
records of interpretations of the standards made by the PIA to determine 
whether they are consistent and to determine whether there are any 
conflicts which should be referred to the Secretary for determination.
    (e) DAPIA. Monitoring parties shall review on a random basis at 
least 10 percent of the design and quality assurance manual approvals 
made by each DAPIA in each year.
    (f) IPIA. The monitoring parties shall assure that the IPIAs are 
carrying out all of the functions for which they have been accepted. In 
particular, they shall assure that the manufacturing process is as 
stated in the certification reports, that the IPIAs are carrying out the 
required number of inspections, that inspections are effective, and that 
the IPIAs are maintaining complete label control as required by Sec. 
3282.362. A monitoring team shall monitor the IPIA's office procedures, 
files, and label control and the monitoring team shall send copies of 
its report to the Secretary or the Secretary's agent, which shall send 
copies to all monitoring teams which monitor the operations of the 
subject IPIA.
    (g) Remedial actions. The monitoring parties shall review the 
remedial action records of the manufacturers and of the primary 
inspection agencies closely to determine whether the primary inspection 
agencies have been carrying out their responsibilities with respect to 
remedial actions.



Sec. 3282.453  Frequency and extent of monitoring.

    (a) The actions of all primary inspection agencies shall be 
monitored at a frequency adequate to assure that they are performing 
consistently and fulfilling their responsibilities under these 
regulations. Every aspect of the primary inspection agencies' 
performance shall be monitored.
    (b) Frequency of monitoring. The performance of each primary 
inspection agency shall be monitored during its period of provisional 
acceptance by a complete review of its records and, in

[[Page 194]]

the case of IPAs, by a complete inspection of the operations of at least 
one manufacturing plant which it has approved or in which it is 
operating. After the initial inspection, the performance of each primary 
inspection agency shall be monitored four times per year, except that 
the number of monitoring visits may be decreased to a minimum of one per 
year if the performance of the primary inspection agency is deemed by 
the Secretary or the Secretary's agent to be superior, and it may be 
increased as necessary if performance is suspect. There shall be a

                            Subpart A_General



Sec. 3285.1  Administration.

    (a) Scope. These Model Installation Standards provide minimum 
requirements for the initial installation of new manufactured homes, in 
accordance with section 605 of the Act (42 U.S.C. 5404). The Model 
Installation Standards are one component of the Manufactured Home 
Installation Program in Part 3286 of this chapter, upon effect, and 
serve as the basis for developing the manufacturers' installation 
instructions required by Sec. 3285.2 of this subpart. The 
manufacturer's installation instructions, including specific methods for 
performing a specific operation or assembly, will be deemed to comply 
with these Model Installation Standards, provided they meet or exceed 
the minimum requirements of these Model Installation Standards and do 
not take the home out of compliance with the Manufactured Home 
Construction and Safety Standards (24 CFR part 3280). Work necessary to 
join all sections of a multi-section home specifically identified in 
Subparts G, H, and I of this part, or work associated with connecting 
exterior lights, chain-hung light fixtures, or ceiling-suspended fans, 
as specifically identified in Subpart I, is not considered assembly or 
construction of the home, although the design of those elements of a 
manufactured home must comply with the Manufactured Home Construction 
and Safety Standards (MHCSS). However, work associated with the 
completion of hinged roofs and eaves in Sec. 3285.801 and other work 
done on-site

[[Page 197]]

and not specifically identified in this part as close-up is considered 
construction and assembly and is subject to the requirements of the 
Manufactured Home Construction and Safety Standards (24 CFR part 3280) 
and the Manufactured Home Procedural and Enforcement Regulations (24 CFR 
part 3282).
    (1) States that choose to operate an installation program for 
manufactured homes in lieu of the federal program must implement 
installation standards that provide protection to its residents that 
equals or exceeds the protection provided by these Model Installation 
Standards.
    (2) In states that do not choose to operate their own installation 
program for manufactured homes, these Model Installation Standards serve 
as the minimum standards for manufactured home installations.
    (b) Applicability. The standards set forth herein have been 
established to accomplish certain basic objectives and are not to be 
construed as relieving manufacturers, retailers, installers, or other 
parties of responsibility for compliance with other applicable 
ordinances, codes, regulations, and laws. The manufactured homes covered 
by this standard must comply with requirements of the U.S. Department of 
Housing and Urban Development's (HUD) MHCSS Program, as set forth in 24 
CFR part 3280, Manufactured Home Construction and Safety Standards, and 
24 CFR part 3282, Manufactured Home Procedural and Enforcement 
Regulations, as well as with, upon effect, the Manufactured Home 
Installation Program, 24 CFR part 3286, and the Dispute Resolution 
Program, 24 CFR part 3288. The requirements of this part do not apply to 
homes installed on site-built permanent foundations when the 
manufacturer certifies the home in accordance with Sec. 3282.12 of this 
chapter.
    (c) Consultation with the Manufactured Housing Consensus Committee. 
The Secretary will seek input from the Manufactured Housing Consensus 
Committee (MHCC) when revising the installation standards in this part 
3285. Before publication of a proposed rule to revise the installation 
standards, the Secretary will provide the MHCC with a 120-day 
opportunity to comment on such revision. The MHCC may send to the 
Secretary any of the MHCC's own recommendations to adopt new 
installation standards or to modify or repeal any of the installation 
standards in this part. Along with each recommendation, the MHCC must 
set forth pertinent data and arguments in support of the action sought. 
The Secretary will either:
    (1) Accept or modify the recommendation and publish it for public 
comment in accordance with section 553 of the Administrative Procedure 
Act (5 U.S.C. 553), along with an explanation of the reasons for any 
such modification; or
    (2) Reject the recommendation entirely, and provide to the MHCC a 
written explanation of the reasons for the rejection.



Sec. 3285.2  Manufacturer installation instructions.

    (a) Instructions required. A manufacturer must provide with each new 
manufactured home, installation designs and instructions that have been 
approved by the Secretary or DAPIA. The approved installation 
instructions must include all topics covered in the Model Installation 
Standards for the installation of manufactured homes. These installation 
instructions and any variations thereto that are prepared to comply with 
paragraph (c) of this section must provide protection to residents of 
the manufactured homes that equals or exceeds the protection provided by 
these Model Installation Standards and must not take the manufactured 
home out of compliance with the MHCSS. These instructions must insure 
that each home will be supported and anchored in a manner that is 
capable of meeting or exceeding the design loads required by the MHCSS.
    (b) Professional engineer or registered architect certification. A 
professional engineer or registered architect must prepare and certify 
that the manufacturer's installation instructions meet or exceed the 
Model Installation Standards for foundation support and anchoring 
whenever:
    (1) The manufacturer's installation instructions do not conform in 
their entirety to the minimum requirements

[[Page 198]]

or tables or their conditions for foundation support and anchoring of 
this Standard; or
    (2) An alternative foundation system or anchoring system is 
employed, including designs for basements and perimeter support 
foundation systems, whether or not it is included in the installation 
instructions; or
    (3) Materials such as metal piers or alternatives to concrete 
footing materials are required by the installation instructions; or
    (4) Foundation support and anchoring systems are designed for use in 
areas subject to freezing or for use in areas subject to flood damage or 
high seismic risk; or
    (5) Foundations support and anchoring systems are designed to be 
used in special snow load conditions or in severe wind design areas; or
    (6) Site conditions do not allow the use of the manufacturer's 
installation instructions; or
    (7) There are any other circumstances in which the manufacturer's 
installation instructions would not permit the home to be installed in 
conformance with the Installation Standards or the MHCSS.
    (c) Variations to installation instructions. (1) Before an installer 
provides support or anchorage that are different than those methods 
specified in the manufacturer's installation instructions, or when the 
installer encounters site or other conditions (such as areas that are 
subject to flood damage or high seismic risk) that prevent the use of 
the instructions, the installer must:
    (i) First attempt to obtain DAPIA-approved designs and instructions 
prepared by the manufacturer; or
    (ii) If designs and instructions are not available from the 
manufacturer, obtain an alternate design prepared and certified by a 
registered professional engineer or registered architect for the support 
and anchorage of the manufactured home that is consistent with the 
manufactured home design, conforms to the requirements of the MHCSS, and 
has been approved by the manufacturer and the DAPIA.
    (2) The manufacturer's installation instructions must include an 
explanation of the requirement in paragraph (c)(1) of this section.
    (d) Installer certification. In making the certification of the 
installation required under part 3286 of this chapter, upon effect, an 
installer must certify that it completed the installation in compliance 
with either the manufacturer's instructions or with an alternate 
installation design and instructions that have been prepared by the 
manufacturer or prepared in compliance with paragraph (c) of this 
section.
    (e) Temporary storage. The installation instructions must provide at 
least one method for temporarily supporting each transportable section 
of a manufactured home, to prevent structural and other damage to the 
structure, when those section(s) are temporarily sited at the 
manufacturer's facility, retailer's lot, or the home site.



Sec. 3285.3  Alterations during initial installation.

    Additions, modifications, or replacement or removal of any equipment 
that affects the installation of the home made by the manufacturer, 
retailer, or installer prior to completion of the installation by an 
installer must equal or exceed the protections and requirements of these 
Model Installation Standards, the MHCSS (24 CFR part 3280) and the 
Manufactured Home Procedural and Enforcement Regulations (24 CFR part 
3282). An alteration, as defined in Sec. 3282.7 of this chapter, must 
not affect the ability of the basic manufactured home to comply with the 
MHCSS, and the alteration must not impose additional loads to the 
manufactured home or its foundation, unless the alteration is included 
in the manufacturer's DAPIA-approved designs and installation 
instructions, or is designed by a registered professional engineer or 
architect consistent with the manufacturer's design and that conforms to 
the requirements of the MHCSS.

    (i) Located in accordance with Table 2 to Sec. 3285.303; or
    (ii) Provided by other means such as additional outriggers or floor 
joists. When this alternative is used, the designs required by Sec. 
3285.301 must consider the additional loads in sizing the pier and 
footing supports under the main chassis beam.

[[Page 216]]

    (b) For roof live loads of 40 psf or greater, a professional 
engineer or architect must determine the maximum sidewall opening 
permitted without perimeter pier or other supports.
    (c) The location and installation of any perimeter pier support must 
not take the home out of compliance with the Manufactured Home 
Construction and Safety Standards (part 3280 of this chapter).



Sec. 3285.312  Footings.

    (a) Materials approved for footings must provide equal load-bearing 
capacity and resistance to decay, as required by this section. Footings 
must be placed on undisturbed soil or fill compacted to 90 percent of 
maximum relative density. A footing must support every pier. Footings 
are to be either:
    (1) Concrete.
    (i) Four inch nominal precast concrete pads meeting or exceeding 
ASTM C 90-02a, Standard Specification for Loadbearing Concrete Masonry 
Units (incorporated by reference, see Sec. 3285.4), without 
reinforcement, with at least a 28-day compressive strength of 1,200 
pounds per square inch (psi); or
    (ii) Six inch minimum poured-in-place concrete pads, slabs, or 
ribbons with at least a 28-day compressive strength of 3,000 pounds per 
square inch (psi). Site-specific soil conditions or design load 
requirements may also require the use of reinforcing steel in cast-in-
place concrete footings.
    (2) Pressure-treated wood.
    (i) Pressure-treated wood footings must consist of a minimum of two 
layers of nominal 2-inch thick pressure-treated wood, a single layer of 
nominal \3/4\-inch thick, pressure-treated plywood with a maximum size 
of 16 inches by 16 inches, or at least two layers of \3/4\-inch thick, 
pressure-treated plywood for sizes greater than 16 inches by 16 inches. 
Plywood used for this purpose is to be rated exposure 1 or exterior 
sheathing, in accordance with PS1-95, Construction and Industrial 
Plywood (incorporated by reference, see Sec. 3285.4).
    (ii) Pressure treated lumber is to be treated with a water-borne 
adhesive, in accordance with AWPA Standard U1-04 (incorporated by 
reference, see Sec. 3285.4) for Use Category 4B ground contact 
applications.
    (iii) Cut ends of pressure treated lumber must be field-treated, in 
accordance with AWPA Standard M4-02 (incorporated by reference, see 
Sec. 3285.4).
    (3) ABS footing pads.
    (i) ABS footing pads are permitted, provided they are installed in 
accordance with the pad manufacturer installation instructions and 
certified for use in the soil classification at the site.
    (ii) ABS footing pads must be listed or labeled for the required 
load capacity.
    (4) Other Materials. Footings may be of other materials than those 
identified in this section, provided they are listed for such use and 
meet all other applicable requirements of this subpart.
    (b) Placement in freezing climates. Footings placed in freezing 
climates must be designed using methods and practices that prevent the 
effects of frost heave by one of the following methods:
    (1) Conventional footings. Conventional footings must be placed 
below the frost line depth for the site unless an insulated foundation 
or monolithic slab is used (refer to Sec. Sec. 3285.312(b)(2) and 
3285.312(b)(3)). When the frost line depth is not available from the 
LAHJ, a registered professional engineer, registered architect, or 
registered geologist must be consulted to determine the required frost 
line depth for the manufactured home site. This is not subject to the 
provisions in Sec. 3285.2(c) that also require review by the 
manufacturer and approval by its DAPIA for any variations to the 
manufacturer's installation instructions for support and anchoring.
    (2) Monolithic slab systems. A monolithic slab is permitted above 
the frost line when all relevant site-specific conditions, including 
soil characteristics, site preparation, ventilation, and insulative 
properties of the under floor enclosure, are considered and anchorage 
requirements are accommodated as set out in Sec. 3285.401. The 
monolithic slab system must be designed by a registered professional 
engineer or registered architect:
    (i) In accordance with acceptable engineering practice to prevent 
the effects of frost heave; or

    (ii) In accordance with SEI/ASCE 32-01 (incorporated by reference, 
see Sec. 3285.4).
    (3) Insulated foundations. An insulated foundation is permitted 
above the frost line, when all relevant site-specific conditions, 
including soil characteristics, site preparation, ventilation, and 
insulative properties of the under floor enclosure, are considered, and 
the foundation is designed by a registered professional engineer or 
registered architect:
    (i) In accordance with acceptable engineering practice to prevent 
the effects of frost heave; or
    (ii) In accordance with SEI/ASCE 32-01 (incorporated by reference, 
see Sec. 3285.4).
    (c) Sizing of footings. The sizing and layout of footings depends on 
the load-bearing capacity of the soil, footings, and the piers. See 
Sec. Sec. 3285.202 and 3285.303, and Table to 3285.312.

    Notes: 1. The footing sizes shown are for square pads and are based 
on the area (in.\2\), shear and bending required for the loads shown. 
Other configurations, such as rectangular or circular configurations, 
can be used, provided the area and depth is equal to or greater than the 
area and depth of the square footing shown in the table, and the 
distance from the edge of the pier to the edge of the footing is not 
less than the thickness of the footing.
    2. The 6 in. cast-in-place values can be used for 4 in. unreinforced 
precast concrete footings.
    3. The capacity values listed have been reduced by the dead load of 
the concrete footing.
    4. Concrete block piers must not exceed their design capacity of 
8,000 lbs. for 8x16 single stack block and 16,000 
lbs. for 16x16 double stack block.
    5. A registered professional engineer or registered architect must 
prepare the design, if the design loads exceed the capacity for single 
or double stack concrete block piers shown in footnote 4.



Sec. 3285.313  Combination systems.

    Support systems that combine both load-bearing capacity and uplift 
resistance must also be sized and designed for all applicable design 
loads.



Sec. 3285.314  [Reserved]



Sec. 3285.315  Special snow load conditions.

    (a) General. Foundations for homes designed for and located in areas 
with roof live loads greater than 40 psf must be designed by the 
manufacturer for the special snow load conditions, in accordance with 
acceptable engineering practice. Where site or other conditions prohibit 
the use of the manufacturer's instructions, a registered professional 
engineer or registered architect must design the foundation for the

loads that the home was designed to withstand required by part 3280, 
subpart D of this chapter, as shown on the home's data plate. Exception: 
Manufactured homes that are installed in less restrictive roof load zone 
and wind zone areas may have foundation or anchorage systems that are 
capable of meeting the lower design load provisions of the Standards, if 
the design for the lower requirements is either provided in the 
installation instructions or the foundation and anchorage system is 
designed by a professional engineer or registered architect.
    (d) The installation instructions are to include at least the 
following information and details for anchor assembly-type 
installations:
    (1) The maximum spacing for installing diagonal ties and any 
required vertical ties or straps to ground anchors;
    (2) The minimum and maximum angles or dimensions for installing 
diagonal ties or straps to ground anchors and the main chassis members 
of the manufactured home;
    (3) Requirements for connecting the diagonal ties to the main 
chassis members of the manufactured home. If the diagonal ties are 
attached to the bottom flange of the main chassis beam, the frame must 
be designed to prevent rotation of the beam;
    (4) Requirements for longitudinal and mating wall tie-downs and 
anchorage;
    (5) The method of strap attachment to the main chassis member and 
ground anchor, including provisions for swivel-type connections;
    (6) The methods for protecting vertical and diagonal strapping at 
sharp corners by use of radius clips or other means; and
    (7) As applicable, the requirements for sizing and installation of 
stabilizer plates.



Sec. 3285.402  Ground anchor installations.

    (a) Ground anchor certification and testing. (1) Each ground anchor 
assembly must be manufactured and provided with installation 
instructions, and must be labeled or otherwise identified and subject to 
an on-going quality assurance surveillance program in accordance with 
its listing or certification (see 24 CFR 3285.5) by a nationally 
recognized testing laboratory. A registered professional engineer or 
architect must certify that each ground anchor assembly is capable of 
resisting all loads in paragraph (c) of this section based on the test 
methods in paragraph (b) of this section for use in soil(s) classified 
in accordance with Sec. 3285.202.
    (2) Each ground anchor assembly that has been listed prior to 
November 10, 2014 is not subject to paragraph (b) of this section, 
provided it has been previously tested in accordance with this 
paragraph. A professional engineer or registered architect must have 
certified the testing. The ground anchor must be listed by a nationally 
recognized testing agency and the listing or certification includes or 
has met all of the following requirements:
    (i) A minimum of three tests meeting all of the requirements of this 
section were conducted for each ground anchor assembly design;

    (ii) Standards for identification of soil and soil classification. 
The soil test torque probe method must be used at the certification test 
site for soil classification. At a minimum, the soil test torque probe 
must be used at three sample locations representative of the extent of 
the certification site test area. Soil characteristics must be measured 
at a depth below ground surface of not greater than the anchor helix 
depth and not less than \2/3\ of the anchor helix depth for each ground 
anchor depth evaluated within the test area. The lowest torque probe 
value resulting in the highest soil classification number must be used. 
Additional guidance regarding the soil test torque probe method is 
available at the Appendix to this section and at Sec. 3282.202.
    (iii) Classification in non-cohesive soils. Ground anchor assemblies 
must be tested and listed or certified, and labeled for use in non-

conducting tests to list or certify a ground anchor assembly for use in 
a classified soil must

[[Page 222]]

be capable of meeting the requirements of paragraph (b)(7) of this 
section as determined by the testing agency.
    (ii) The testing equipment shall be calibrated to meet the testing 
requirements of paragraph (b)(7) of this section as determined by the 
testing agency.
    (5) Test specimens details and selection. (i) Test specimens are to 
be examined by the independent testing, listing, or certifying entity 
for conformance with engineered drawings, specifications, and other 
information provided by the ground anchor manufacturer or producer 
including:
    (A) Dimensions and specifications on all welds and fasteners;

    Note to paragraph (b)(6):
    As a recommended practice, the test rig soil reactions (bearing 
pads) should not be located closer to the center of the anchor assembly 
(anchor head) than the lesser of D, 4d, or 32 inches where D is the 
depth of the anchor helix and d is the diameter of the anchor helix, 
both in inches. However, experience with a particular test rig, types of 
anchors, and soil conditions may justify other acceptable dimensional 
tolerances.
    (7) Field tests of anchor assemblies. (i) The soil characteristics 
at the certification test site must be identified and recorded according 
to paragraph (b)(3) of this section. The date, approximate time, and 
names of persons conducting and witnessing the anchor assembly tests 
must also be recorded at each certification test site.
    (ii) Connection of the testing apparatus to the anchor assembly head 
must provide loading conditions to the anchor head, similar to actual 
site conditions. Adequacy of the connection must be determined by the 
testing agency or test engineer.
    (iii) For soil classifications 3, 4A, and 4B, testing must be 
performed in the lower 50 percentile torque probe value of the soil 
classification being tested. For soil classifications 1 and 2 the torque 
probe value must not exceed 750 inch-pounds.
    (iv) A minimum of three tests must be performed and the result of 
each test must meet or exceed 4,725 pounds pull (3,150 x 1.5 factor of 
safety) in the direction of pull.
    (v) Special-purpose anchor assemblies, including those needed to 
accommodate unique design loads identified by manufacturers in their 
installation instructions, may be certified under this section or to 
more stringent requirements such as higher working loads, more 
restrictive anchor head displacements and/or tested angle limitations.
    (vi) Angle of pull. Where the test apparatus configuration results 
in a changing angle of pull due to anchor assembly displacement during a 
lateral angle pull test, the angle of pull at the ultimate anchor load 
is to be recorded as the load angle for the test. Load angles are to be 
measured relative to the plane of the ground surface and shall be 
permitted to be rounded to the nearest 5-degree increment.
    (vii) Displacement measurement. Vertical displacement (for all 
tests) and horizontal displacement (for lateral angle pull tests) must 
be measured relative to the centerline of the test apparatus' connection 
to the ground anchor assembly (anchor head) and the ground. A stable 
ground reference point for displacement measurements must be located 
independent of the test apparatus and not closer to the anchor assembly 
than the soil reaction points of the test apparatus. Displacement 
measurements shall be taken using a device with not less than \1/8\-inch 
reading increments. Measurements shall be permitted to be rounded to the 
nearest \1/8\-inch increment.

                       Appendix to Sec. 3285.402

    Torque Probe Method for determining soil classification: This kit 
contains a 5-foot long steel earth-probe rod, with a helix at the end. 
It resembles a wood-boring bit on a larger scale. The tip of the probe 
is inserted as deep as the bottom helix of the ground anchor assembly 
that is being considered for installation. The torque wrench is placed 
on the top of the probe. The torque wrench is used to rotate the probe 
steadily so one can read the scale on the wrench. If the torque wrench 
reads 551 inch-pounds or greater, then a Class 2 soil is present 
according to the Table to 24 CFR 3285.202(a)(3). A Class 3 soil is from 
351 to 550 inch-pounds. A Class 4A soil is from 276 to 350 inch-pounds, 
and a Class 4B soil is from 175 to 275 inch-pounds. When the torque 
wrench reading is below 175 inch-pounds, a professional engineer should 
be consulted.

Sec. 3286.507  Verifying installation.

    (a) Verification by inspector. When an inspector is satisfied that 
the manufactured home has been installed in accordance with the 
requirements of this part, the inspector must provide verification of 
the installation in writing and return the evidence of such verification 
to the installer.
    (b) Certification by installer. (1) Once an installation has been 
inspected and verified, the installer is permitted to certify the 
installation as provided in Sec. 3286.111. The installer must provide a 
signed copy of the certification to:
    (i) The retailer that contracted with the purchaser for the sale of 
the home;
    (ii) The purchaser; and
    (iii) Any other person that contracted to obtain the services of the 
installer for the installation work on the home.
    (2) The installer must retain records in accordance with Sec. 
3286.413.



Sec. 3286.509  Reinspection upon failure to pass.

    (a) Procedures for failed inspection. If the inspector cannot verify 
the installation of the manufactured home, the inspector must 
immediately notify the installer of any failures to comply with the 
installation standards and explain the reasons why the inspector cannot 
issue verification that the installation complies with the requirements 
of this part. After the installation is corrected, it must be 
reinspected before verification can be issued.

[[Page 264]]

    (b) Cost of reinspection. If there is any cost for the reinspection 
of an installation that an inspector has refused to verify, that cost 
must be paid by the installer or the retailer and, absent a written 
agreement with the purchaser that specifically states otherwise, that 
cost cannot be charged to the purchaser of the manufactured home.



Sec. 3286.511  Inspector qualifications.

    (a) Qualifications. Any individual or entity who meets at least one 
of the following qualifications is permitted to review the work and 
verify the installation of a manufactured home that is subject to the 
requirements of the HUD-administered installation program:
    (1) A manufactured home or residential building inspector employed 
by the local authority having jurisdiction over the site of the home, 
provided that the jurisdiction has a residential code enforcement 
program;
    (2) A professional engineer;
    (3) A registered architect;
    (4) A HUD-accepted Production Inspection Primary Inspection Agency 
(IPIA) or a Design Approval Primary Inspection Agency (DAPIA); or
    (5) An International Code Council certified inspector.
    (b) Independence required. The inspector must be independent of the 
manufacturer, the retailer, the installer, and any other person that has 
a monetary interest, other than collection of an inspection fee, in the 
completion of the sale of the home to the purchaser.
    (c) Suspension or revocation of inspection authority. After notice 
and an opportunity for a presentation of views in accordance with 
subpart D of part 3282 of this chapter, the Secretary may suspend or 
revoke an inspector's authority to inspect manufactured home 
installations under this part in HUD-administered states. An inspector's 
authority may be suspended or revoked for cause. In deciding whether to 
suspend or revoke an inspector's authority to conduct such installation 
inspections, the Secretary will consider the impact of the suspension or 
revocation on other affected parties and will seek to assure that the 
sales and siting of manufactured homes are not unduly disrupted.
    (d) Reinstating inspection authority. An inspector whose authority 
to inspect manufactured home installations in HUD-administered states 
has been suspended or revoked under this section may apply for 
reauthorization by contacting: Administrator, Office of Manufactured 
Housing Programs, HUD, 451 Seventh Street, SW., Room 9164, Washington, 
DC 20410-8000, or to a fax number or e-mail address obtained by calling 
the Office of Manufactured Housing Programs at the toll-free telephone 
number 1-800-927-2891, extension 57.



     Subpart G_Retailer Responsibilities in HUD-Administered States



Sec. 3286.601  Purpose.

    The purpose of this subpart G is to set out the requirements that 
apply to a retailer with respect to the federal installation 
requirements applicable to new manufactured homes that the retailer 
sells or leases and that will be installed in states that do not have 
qualifying installation programs. These requirements are in addition to 
other requirements that apply to retailers of manufactured homes 
pursuant to other parts of this chapter.



Sec. 3286.603  At or before sale.

    (a) Before contract. (1) The retailer is required to support each 
transportable section of a manufactured home that is temporarily or 
permanently located on a site used by a retailer in accordance with the 
manufacturer's instructions.
    (2) Before a purchaser or lessee signs a contract of sale or lease 
for a manufactured home, the retailer must:
    (i) Provide the purchaser or lessee with a copy of the consumer 
disclosure statement required in Sec. 3286.7(b); and
    (ii) Verify that the wind, thermal, and roof load zones of the home 
being purchased or leased are appropriate for the site where the 
purchaser or lessee plans to install the home for occupancy; and
    (iii) If the cost of inspection of the home's installation is not 
included in the sales price of the home, provide the disclosure required 
in Sec. 3286.7(b).
    (b) Occupancy site not known. When at the time of purchase the 
purchaser does not know the locale for the initial

[[Page 265]]

siting of the home for occupancy, the retailer must advise the purchaser 
that:
    (1) The home was designed and constructed for specific wind, 
thermal, and roof load zones; and
    (2) If the home is sited in a different zone, the home may not pass 
the required installation inspection because the home will have been 
installed in a manner that would take it out of compliance with the 
construction and safety standards in part 3280 of this chapter.
    (c) Verification of installer license.When the retailer or 
manufacturer agrees to provide any set up in connection with the sale or 
lease of the home, the retailer or manufacturer must verify that the 
installer is licensed in accordance with these regulations.



Sec. 3286.605  After sale.

    (a) Tracking installation information. The retailer is responsible 
for providing to HUD the information required pursuant to Sec. 
3286.113.
    (b) Other tracking and compliance requirements. The retailer 
continues to be responsible for compliance with the tracking and 
compliance requirements set out in subpart F of part 3282 of this 
chapter, which are related to HUD construction and safety standards.



Sec. 3286.607  Recordkeeping.

    The retailer is responsible for the reporting and recordkeeping 
requirements under Sec. 3286.113.



     Subpart H_Oversight and Enforcement in HUD-Administered States



Sec. 3286.701  Purpose.

    The purpose of this subpart H is to set out the mechanisms by which 
manufacturers, retailers, distributors, installers, and installation 
inspectors will be held accountable for assuring the appropriate 
installation of manufactured homes. The requirements in subpart A of 
this part are applicable in all states, the requirements in subparts B 
through H are applicable in states where the HUD-administered 
installation program operates, and the requirements in subpart I are 
applicable in states with qualifying installation programs. It is the 
policy of the Secretary, regarding manufactured home installation 
program enforcement matters, to cooperate with state or local agencies 
having authority to regulate the installation of manufactured homes. In 
addition to actions expressly recognized under this subpart H and other 
provisions in this part, however, HUD may take any actions authorized by 
the Act in order to oversee the system established by the regulations in 
this part.



Sec. 3286.703  Failure to comply.

    (a) Penalties and injunctive relief. Failure to comply with the 
requirements of this part is a prohibited act under section 610(a)(7) of 
the Act, 42 U.S.C. 5409(a). Any person who fails to comply with the 
requirements of this part is subject to civil and criminal penalties, 
and to actions for injunctive relief, in accordance with sections 611 
and 612 of the Act, 42 U.S.C. 5410 and 5411.
    (b) Presentation of views. When practicable, the Secretary will 
provide notice to any person against whom an action for injunctive 
relief is contemplated and will afford such person an opportunity to 
request a presentation of views. The procedures set forth in Sec. Sec. 
3282.152 through 3282.154 of this chapter shall apply to each request to 
present views and to each presentation of views authorized in accordance 
with this section.
    (c) Investigations. The procedures for investigations and 
investigational proceedings are set forth in part 3800 of this chapter.



Sec. 3286.705  Applicability of dispute resolution program.

    (a) Generally. Regardless of any action taken under Sec. 3286.703, 
for any defect in a manufactured home that is reported during the one-
year period beginning on the date of installation, as specified in Sec. 
3286.115, any rights and remedies available under the HUD dispute 
resolution program, as implemented in part 3288 of this chapter, 
continue to apply as provided in that part.
    (b) Waiver of rights invalid. Any provision of a contract or 
agreement entered

[[Page 266]]

into by a manufactured home purchaser that seeks to waive any recourse 
to either HUD or a state dispute resolution program is void.



                        Subpart I_State Programs



Sec. 3286.801  Purpose.

    The purpose of this subpart I is to establish the requirements that 
must be met by a state to implement and administer its own installation 
program, either as part of its approved state plan or under this 
subpart, in such a way that the state would not be covered by the HUD-
administered installation program. This subpart I also establishes the 
procedure for determining whether a state installation program meets the 
requirements of the Act for a qualifying installation program that will 
operate in lieu of the HUD-administered installation program.



Sec. 3286.803  State qualifying installation programs.

    (a) Qualifying installation program supersedes. The HUD-administered 
installation program will not be implemented in any state that is 
identified as fully or conditionally accepted under the requirements and 
procedures of this subpart I or in accordance with part 3282 of this 
chapter.
    (b) Minimum elements. To be accepted as a fully qualifying 
installation program, a state installation program must include the 
following elements:
    (1) Installation standards that meet or exceed the requirements of 
Sec. 3286.107(a) and that apply to every initial installation of a new 
manufactured home within the state;
    (2) The training of manufactured home installers;
    (3) The licensing of, or other method of certifying or approving, 
manufactured home installers to perform the initial installations of new 
manufactured homes in the state;
    (4) A method for inspecting the initial installations of new 
manufactured homes in the state that is implemented and used to hold 
installers responsible for the work they perform; and
    (5) Provision of adequate funding and personnel to administer the 
state installation program.
    (c) Conditional acceptance. (1) A state installation program that 
meets the minimum requirements set forth under paragraphs (b)(1), (4), 
and (5) of this section may be conditionally accepted by the Secretary 
if the state provides assurances deemed adequate by the Secretary that 
the state is moving to meet all of the requirements for full acceptance. 
If the Secretary conditionally accepts a state's installation program, 
the Secretary will provide to the state an explanation of what is 
necessary to obtain full acceptance.
    (2) A conditionally accepted state will be permitted to implement 
its own installation program in lieu of the HUD-administered program for 
a period of not more than 3 years. The Secretary may for good cause 
grant an extension of conditional approval upon petition by the state.
    (d) Limited exemptions from requirements. A state installation 
program may be accepted by the Secretary as a qualifying installation 
program if the state can demonstrate that it lacks legal authority, as a 
matter of federal law, to impose the minimum requirements set forth 
under paragraph (b) of this section in certain geographic areas of the 
state, but that the minimum requirements do apply in all other 
geographic areas of the state.



Sec. 3286.805  Procedures for identification as qualified installation
program.

    (a) Submission of certification. (1) A state seeking identification 
as having a qualified installation program must submit a completed State 
Installation Program Certification form to the Secretary for review and 
acceptance and indicate if the installation program will be part of its 
approved state plan in accordance with part 3282 of this chapter.
    (2) A state must include a qualified installation program as part of 
any state plan application submitted for approval under Sec. 3282.302 
of this chapter, if the state does not have a fully or conditionally 
approved state plan in effect at the time of submission of the state 
plan application. In all other cases, a qualified installation program 
is permitted, but is not required, to be

[[Page 267]]

submitted as a part of a state plan approved in accordance with Sec. 
3282.305 of this chapter.
    (b) HUD review and action. (1) The Secretary will review the State 
Installation Program Certification form submitted by a state and may 
request that the state submit additional information as necessary. 
Unless the Secretary has contacted the state for additional information 
or has conditionally accepted or rejected the state installation 
program, the state installation program will be considered to have been 
accepted by the Secretary as a fully qualifying installation program as 
of the earlier of:
    (i) Ninety days after the Secretary receives the state's completed 
State Installation Program Certification form; or
    (ii) The date that the Secretary issues notification to the state of 
its full acceptance.
    (2) A notice of full or conditional acceptance will include the 
effective date of acceptance.
    (c) Rejection of state installation program. (1) If the Secretary 
intends to reject a state's installation program, the Secretary will 
provide to the state an explanation of what is necessary to obtain full 
or conditional acceptance. The state will be given 90 days from the date 
the Secretary provides such explanation to submit a revised State 
Installation Program Certification form.
    (2) If the Secretary decides that any revised State Installation 
Program Certification form is inadequate, or if the state fails to 
submit a revised form within the 90-day period or otherwise indicates 
that it does not intend to change its form, the Secretary will notify 
the state that its installation program is not accepted.
    (3) A state whose State Installation Program Certification form is 
rejected has a right to a presentation of views on the rejection using 
the procedures set forth under subpart D of part 3282 of this chapter. 
The state's request for a presentation of views must be submitted to the 
Secretary within 60 days after the Secretary has provided notification 
that the state's installation program has been rejected.



Sec. 3286.807  Recertification required.

    (a) Recertification. To maintain its status as a qualified 
installation program when the installation program is not part of the 
approved state plan in accordance with part 3282 of this chapter, a 
state must submit a new State Installation Program Certification form to 
the Secretary for review and action as follows:
    (1) Every 5 years after the state's most recent certification as a 
qualified installation program; and
    (2) Whenever there is a change to the state's installation program 
or a change in the HUD requirements applicable to qualifying 
installation programs such that the state's installation program no 
longer complies with the minimum requirements set forth in Sec. 
3286.803(b), regardless of when the state's next regular recertification 
of its installation program would be due.
    (b) Due date of recertification. (1) A state's recertification 
required in paragraph (a) of this section must be filed within 90 days 
of, as applicable:
    (i) The 5-year anniversary of the effective date of the Secretary's 
acceptance of the state's most recent certification as a qualified 
installation program; and
    (ii) The effective date of the state or HUD action that makes a 
significant change to the state's installation program.
    (2) Upon petition by the state, the Secretary may for good cause 
grant an extension of the deadline for recertification.
    (c) Failure to Recertify. (1) A state whose certification of its 
installation program, when the installation program is not part of the 
approved state plan in accordance with part 3282 of this chapter, has 
been accepted by the Secretary is permitted to administer its 
installation program in lieu of the HUD-administered installation 
program until the effective date of a notification by the Secretary that 
the state's certification of its installation program is no longer 
approved.
    (2) A state whose recertification of its installation program is 
rejected by the Secretary has a right to a presentation of views on the 
rejection using the procedures set forth under subpart D of part 3282 of 
this chapter. The

[[Page 268]]

state's request for a presentation of views must be submitted to the 
Secretary within 60 days after the Secretary has provided notification 
that the state's recertification of its installation program has been 
rejected.



Sec. 3286.809  Withdrawal of qualifying installation program status.

    (a) Voluntary withdrawal. Any state that intends to withdraw from 
its responsibilities to administer a qualifying installation program 
should provide the Secretary with a minimum of 90 days notice.
    (b) Involuntary withdrawal. Whenever the Secretary finds, after 
affording notice and an opportunity for a hearing in accordance with 
subpart D of part 3282 of this chapter, that a state installation 
program fails to comply substantially with any provision of the 
installation program requirements or that the state program has become 
inadequate, the Secretary will notify the state of withdrawal of 
acceptance or conditional acceptance of the state installation program. 
The HUD-administered installation program will begin to operate in such 
state at such time as the Secretary establishes in issuing the finding.



Sec. 3286.811  Effect on other manufactured housing program requirements.

    A state with a qualifying installation program will operate in lieu 
of HUD with respect to only the installation program established under 
subparts B through H of this part. No state may permit its installation 
program, even if it is a qualified installation program under this part, 
to supersede the requirements applicable to HUD's Manufactured Housing 
Construction and Safety Standards and enforcement programs. Regardless 
of whether a state has a qualified installation program:
    (a) Construction and safety standards. Any responsibilities, rights, 
and remedies applicable under the Manufactured Home Construction and 
Safety Standards Act in part 3280 of this chapter and the Manufactured 
Home Procedural and Enforcement Regulations in part 3282 of this chapter 
continue to apply as provided in those parts; and
    (b) Dispute resolution. For any defect in a manufactured home that 
is reported during the one-year period beginning on the date of 
installation defined in Sec. 3286.115, any responsibilities, rights, 
and remedies applicable under the HUD dispute resolution program as 
implemented in part 3288 of this chapter continue to apply as provided 
in that part.



Sec. 3286.813  Inclusion in state plan.

    If a state installation program is included in a state plan approved 
in accordance with Sec. 3282.302 of this chapter, the state 
installation program is subject to all of the requirements for such a 
state plan, including annual review by HUD.

                            Subpart A_General



Sec. 3288.1  Purpose and scope.

    (a) Purpose. The Act is intended, in part, to protect the quality, 
safety, durability, and affordability of manufactured homes. Section 
623(c)(12) of the Act (42 U.S.C. 5422 (c)(12)) requires the 
implementation of ``a dispute resolution program for the timely 
resolution of disputes between manufacturers, retailers, and installers 
of manufactured homes regarding responsibility, and for the issuance of 
appropriate orders, for the correction or repair of defects in 
manufactured homes that are reported during the 1-year period beginning 
on the date of installation.'' The purpose of this part is to provide a 
dispute resolution program for the timely resolution of disputes among 
manufacturers, retailers, and installers regarding the responsibility 
for correction or repair of defects reported by the homeowner or others 
and reported in the 1-year period after the first installation of the 
manufactured home.
    (b) Scope--(1) Applicability. In carrying out this purpose, it is 
presumed that if a manufactured home contains an alleged defect that is 
reported in the first year after installation and was not caused by the 
homeowner, then the manufacturer, retailer, or installer is responsible 
for the alleged defect and the dispute resolution process recognized in 
this part is an appropriate means for resolving disputes about 
responsibility for correction and repair of the alleged defect. For 
purposes of the dispute resolution process recognized in this part, only 
alleged defects reported in the first year after the first installation 
are covered by the process. The state where the home is sited determines 
whether the HUD Manufactured Home Dispute Resolution Program or a state 
program applies. Subpart A of this part establishes general provisions 
applicable to HUD's implementation of a dispute resolution program as 
required by the Act. Subpart B of this part establishes the HUD 
Manufactured Home Dispute Resolution Program that HUD will administer in 
any state that does not establish a program that complies with the Act 
and been accepted by HUD as provided in subpart D of this part. Subpart 
C of this part provides an Alternative Process for manufacturers, 
retailers, and installers who agree that a homeowner is not responsible 
for the alleged defect to resolve their disputes about responsibility 
for correction or repair outside of the HUD Mediation and Arbitration 
Process under subpart B. Subpart D of this part establishes the minimum 
requirements that must be met by a state applying to implement its own 
dispute resolution program that complies with the Act, and the procedure 
for determining whether the requirements for complying have been met. 
Subpart E of this part establishes special rulemaking procedures that 
apply to the issuance of new regulations that implement the dispute 
resolution requirements set forth in section 623 of the Act (42 U.S.C. 
5422).
    (2) Warranties not affected. This part is not a warranty program and 
the requirements established in this part do not replace the 
manufacturer's or any other warranty program. Such warranty program may 
have its own requirements.



Sec. 3288.3  Definitions.

[[Page 270]]

is ready for occupancy, the date of installation is the date of closing 
under the purchase agreement or sales contract for the manufactured 
home.
    Day means a calendar day.
    Defect means any defect in the performance, construction, 
components, or material of a manufactured home that renders the home or 
any part of the home not fit for the ordinary use for which it was 
intended, including, but not limited to, a defect in the construction, 
safety, or installation of the home. For purposes of state certification 
under Sec. 3288.205, HUD will find it acceptable if the threshold for 
the state's program is functionally equivalent to this definition.

enforcement of the standards pursuant to section 623 of the Act, 42 
U.S.C. 5422.
    Timely reporting means the reporting of an alleged defect within 1 
year after the date of installation of a manufactured home in accordance 
with Sec. 3288.20.
    Timely resolution means the resolution of disputes among 
manufacturers, retailers, and installers within 120 days of the time a 
request for dispute resolution is made, except that if the defect 
presents an unreasonable risk of injury, death, or significant loss or 
damage to valuable personal property, the resolution must be within 60 
days of the time a request for dispute resolution is made.



Sec. 3288.5  Retailer notification at sale.

    Retailer notice at the time of signing. At the time of signing a 
contract for sale or lease for a manufactured home, the retailer must 
provide the purchaser with a retailer notice. This notice may be in a

assistance or dispute resolution program. For additional information 
about these programs, see sections titled ``Dispute Resolution Process'' 
and ``Additional Information--HUD Manufactured Home Dispute Resolution 
Program'' in the Consumer Manual required to be provided to the 
purchaser. These programs are not warranty programs and do not replace 
the manufacturer's, or any other person's, warranty program.



   Subpart B_HUD Manufactured Home Dispute Resolution Program in HUD-
                           Administered States



Sec. 3288.10  Applicability.

    The requirements of the HUD Manufactured Home Dispute Resolution 
Program established in this subpart B apply in each state that does not 
establish a state dispute resolution program that complies with the Act 
and has been accepted by HUD as provided in subpart D of this part.



Sec. 3288.15  Eligibility for dispute resolution.

    (a) Initiation of actions. Manufacturers, retailers, and installers 
of manufactured homes are eligible to initiate

[[Page 271]]

and participate in the HUD Manufactured Home Dispute Resolution Program. 
Homeowners may initiate action under, and be observers to, the HUD 
Manufactured Home Dispute Resolution Program.
    (b) Eligible disputes. Only disputes concerning alleged defects that 
have been reported to the manufacturer, retailer, installer, HUD, or a 
State Administrative Agency within 1 year after the date of the first 
installation of the manufactured home are eligible for resolution 
through the HUD Manufactured Home Dispute Resolution Program. The 
eligible dispute includes the defect alleged in a timely report and any 
related issues.



Sec. 3288.20  Reporting a defect.

    (a) Making a report. To preserve the right to request dispute 
resolution through HUD, alleged defects must be reported to the 
manufacturer, retailer, installer, HUD, or a State Administrative 
Agency. An alleged defect may be reported by a homeowner, manufacturer, 
retailer, or installer.
    (b) Form of report. It is recommended that alleged defects be 
reported in writing, including, but not limited to, e-mail, written 
letter, certified mail, or fax. The existence of an alleged defect may 
also be reported by telephone.
    (c) Content of report. No particular form or format is required to 
report an alleged defect, but any such report must, at a minimum, 
include a description of the alleged defect, the name of homeowner, and 
the address of the home.
    (d) Record of report--(1) To evidence timeliness. To establish 
timely reporting, the report of an alleged defect that is made to the 
manufacturer, retailer, installer, or a State Administrative Agency of 
the manufactured home should be done in a manner that will create a 
dated record of the report that demonstrates that the report was made 
within 1 year after the date of installation; for example, by certified 
mail, fax, or email. Persons who report an alleged defect by telephone 
should make a contemporaneous note of the telephone call, including 
date, time, the name of the person who received the report, the name of 
the business contacted, and the telephone number called. If the matter 
goes to arbitration, the arbitrator and HUD will review whether there is 
sufficient evidence to believe the report was made on a timely basis.
    (2) Obligation to retain. Each report of a defect, including logs of 
telephonic complaints, received by a manufacturer, retailer, a State 
Administrative Agency or installer, must be maintained for 3 years from 
the date of receipt.
    (e) Reports made to a State Administrative Agency. Reports of 
defects in the manufactured home that are made in the first year after 
its installation can be sent to the appropriate State Administrative 
Agency. Contact information about a State Administrative Agency is 
available at http://www.hud.gov. Contact the appropriate State 
Administrative Agency to determine the method for making the report.
    (f) Reports made to HUD. Reports of alleged defects in the 
manufactured home that are made in the first year after its installation 
can be sent to HUD. The report to HUD may be made using any of the 
following methods:
    (1) In writing at: HUD, Office of Regulatory Affairs and 
Manufactured Housing, Attn: Dispute Resolution, 451 Seventh Street, SW., 
Washington, DC 20410-8000;
    (2) By telephone at: (202) 708-6423 or (800) 927-2891;
    (3) By fax at: (202) 708-4213; or
    (4) By e-mail at [email protected].
    (g) Effect of report. The reporting of an alleged defect does not 
initiate the HUD Manufactured Home Dispute Resolution Program, but only 
establishes whether the requirement of timely reporting in accordance 
with Sec. 3288.15(b) has been met. The HUD Manufactured Home Dispute 
Resolution Process is initiated when a request for dispute resolution is 
submitted to HUD in accordance with Sec. 3288.25.



Sec. 3288.25  Initiation of dispute resolution.

    (a) Preliminary effort. HUD strongly encourages the homeowner or 
party reporting an alleged defect to seek to resolve the dispute 
directly with any manufacturer, retailer, or installer

[[Page 272]]

that the person reporting the defect believes to be responsible before 
initiating the HUD dispute resolution process.
    (b) Request for dispute resolution. Any of the parties or the 
homeowner may initiate the HUD Manufactured Home Dispute Resolution 
Program at any time after an alleged defect has been reported, by 
requesting dispute resolution, as follows:
    (1) By mailing, e-mailing, or otherwise delivering a written request 
for dispute resolution to the dispute resolution provider at the address 
or e-mail address provided either at http://www.hud.gov, or by 
contacting HUD's Office of Regulatory Affairs and Manufactured Housing 
at (202) 708-6423 or (800) 927-2891;
    (2) By faxing a request for dispute resolution to the fax number 
provided either at http://www.hud.gov, or by contacting HUD's Office of 
Regulatory Affairs and Manufactured Housing at (202) 708-6423 or (800) 
927-2891; or
    (3) By telephoning a request for dispute resolution to the number 
provided either at http://www.hud.gov, or by contacting HUD's Office of 
Regulatory Affairs and Manufactured Housing at (202) 708-6423 or (800) 
927-2891.
    (c) Requested information. The dispute resolution provider will 
request at least the following information when a person seeks to 
initiate dispute resolution under the HUD Manufactured Home Dispute 
Resolution Program:
    (1) The name, address, and contact information of the homeowner;
    (2) The name and contact information of the manufacturer, retailer, 
and installer of the manufactured home, to the extent available;
    (3) The date the report of the alleged defect was made;
    (4) The name and contact information of the recipient or recipients 
of the report of the alleged defect;
    (5) The date of installation of the manufactured home affected by 
the alleged defect; and
    (6) A description of the alleged defect.



Sec. 3288.30  Screening of dispute resolution request.

    (a) Review for sufficiency. When the request for dispute resolution 
has been received by the dispute resolution provider, a screening 
neutral will review the sufficiency of the information provided in the 
request for dispute resolution and determine if the dispute resolution 
process should proceed. If the screening neutral determines that a 
defect is properly alleged and timely reported, notice of the request 
will be forwarded, as provided in Sec. 3288.33, to the manufacturer, 
retailer, and installer, as appropriate and to the extent the 
appropriate parties can be identified based on the information in the 
request.
    (b) Insufficient information. If a request for dispute resolution is 
lacking any information necessary to determine if the dispute resolution 
process should proceed, the screening neutral will contact the requester 
or the parties about supplementing the initial request. If information 
necessary to qualify the matter for the HUD Manufactured Home Dispute 
Resolution Program is not received within a reasonable time established 
by the screening neutral, the request for dispute resolution will be 
considered withdrawn.
    (c) Denial of a dispute. Denial by all of the parties that there is 
a dispute does not preclude the dispute resolution process from going 
forward to mediation. A screening neutral's determination that a defect 
is properly alleged is prima facie evidence of a dispute. If the defect 
has not been corrected or repaired, the matter will be referred to 
mediation.
    (d) Determination of unreasonable risk. If the screening neutral 
determines there is sufficient documentation of an alleged defect 
presenting an unreasonable risk of injury or death, he or she will send 
a copy of the request to HUD.



Sec. 3288.33  Notice of dispute resolution.

    (a) Once the screening neutral determines that a defect is properly 
alleged and timely reported, notice about the request will be forwarded 
to the parties by overnight delivery, commercial carrier, or fax.
    (b) If the parties have not initiated the Alternative Process in 
accordance with Sec. 3288.105 of this part within 7 days of the 
screening neutral's notification, the screening neutral will refer the 
matter to mediation.

[[Page 273]]



Sec. 3288.35  Mediation.

    (a) Mediator. The dispute resolution provider will provide for the 
selection of a mediator. The selected mediator will not be the person 
who screened the dispute resolution request. The selected mediator will 
mediate the dispute and attempt to facilitate a settlement. If a party 
identifies any other party that should be included in the mediation, the 
mediator will contact the other party and provide information about the 
scheduled mediation meetings.
    (b) Time--(1) For reaching settlement. Except as provided in 
paragraph (b)(2) of this section, the parties are allowed 30 days from 
the commencement of the mediation to reach a mediated settlement. In 
every case, the dispute resolution provider will notify the parties and 
the homeowner, in writing, of the date of the commencement of the 
mediation.
    (2) Alleged defects presenting an unreasonable risk of injury, 
death, or significant loss or damage to valuable personal property. For 
mediations involving alleged defects that appear to present an 
unreasonable risk of injury, death, or significant loss or damage to 
valuable personal property as determined by the screening neutral, the 
parties have a maximum 10 days from the commencement of the mediation to 
reach a settlement.
    (3) For corrective repairs. Unless a longer period is agreed to in 
writing by the parties to the mediated settlement and the homeowner, 
corrective repairs must be completed no later than 30 days after the 
date the settlement agreement is signed by the applicable parties.
    (c) Denial of dispute. During mediation, denial of a dispute by all 
parties without acceptance of responsibility will result in the mediator 
referring the matter to arbitration for determination of the defect and 
responsibility for the defect.
    (d) Written settlement agreement.
    (1) Upon reaching an agreement, the parties will sign a written 
settlement agreement. The dispute resolution provider will forward 
copies of the agreements with the original signatures of the parties to 
the parties, the homeowner, and to HUD.
    (2) Sample agreements will be made available to the parties as 
drafting guidance by the dispute resolution provider.
    (e) Failure of mediation. If mediation is not successful, parties or 
the homeowner may proceed to nonbinding arbitration, as provided in 
Sec. 3288.40 of this part.
    (f) Confidentiality. Except for the report of an alleged defect, any 
request for dispute resolution, and any written settlement agreement, 
all other documents and communications provided in confidence and used 
in the mediation will be confidential, in accordance with the 
Administrative Dispute Resolution Act of 1996 (5 U.S.C. 571 et seq.).



Sec. 3288.40  Nonbinding arbitration.

    (a) When initiated. (1) If, following mediation under Sec. 3288.35, 
the parties fail to reach a settlement, any party or the homeowner may, 
within 15 days of the expiration of the deadline applicable under Sec. 
3288.35(b), initiate nonbinding arbitration.
    (2) In addition, arbitration may be initiated upon referral by the 
mediator pursuant to Sec. 3288.35(c).
    (b) Written request--(1) Submission to HUD. A written request for 
arbitration must be submitted to the dispute resolution provider. 
Information about the dispute resolution provider and how to make a 
request for dispute resolution will be available at http://www.hud.gov 
or by contacting HUD's Office of Manufactured Housing Programs at (202) 
708-6423 or (800) 927-2891.
    (2) Contents of request. The written request for arbitration must 
include:
    (i) The name and address of the party making the request;
    (ii) A brief description of the alleged defect or a copy of the 
report of the alleged defect; and
    (iii) A copy of the request for dispute resolution.
    (c) Appointment and authority of arbitrator. Upon receipt of the 
request, the dispute resolution provider will select an arbitrator. The 
arbitrator will have the authority to:
    (1) Set hearing dates and deadlines;
    (2) Conduct on-site inspections;
    (3) Issue requests for documentation and information necessary to 
complete the record;

[[Page 274]]

    (4) Dismiss frivolous allegations;
    (5) Make proposed findings, including findings of defect and 
culpability and a disposition recommendation to HUD; and
    (6) Recommend apportionment of the responsibility of paying for or 
providing any correction or repair of the home when recommending that 
culpability be assessed to more than one party.
    (d) Denial of dispute. If the parties deny a dispute exists and the 
arbitrator determines there is a defect, the arbitrator will make a 
determination of responsibility for the defect.
    (e) Notice to parties. The dispute resolution provider will provide 
the parties and the homeowner with a notice setting forth the date, 
place, and time an arbitration is to be held.
    (f) Proceedings. (1) If all parties do not request an in-person 
hearing under paragraph (f)(2) of this section within 5 days of the 
dispute resolution provider's receipt of the request for arbitration, or 
if the arbitrator rejects the request for an in-person hearing, the 
arbitrator may conduct either a record review or a telephonic hearing.
    (2) If any party wants to request an in-person hearing, in which the 
parties or their representatives may personally appear before the 
arbitrator, the arbitrator will consider such a request if it is made by 
all of the parties that are participating in the arbitration. Such an 
in-person hearing will be held at the discretion of the arbitrator, 
after considering appropriate factors, such as cost.
    (g) Effect on nonparticipating parties. If a party chooses not to 
participate in the arbitration, the process will continue without 
further input from that party. In such a case, the arbitrator may rely 
on the record developed through the arbitration to find a 
nonparticipating party responsible for correction or repair of a defect.
    (h) Completion of arbitration. (1) Unless an extension is granted 
for good cause by HUD, the arbitrator, within 21 days of the dispute 
resolution provider's receipt of the request for arbitration, the 
arbitrator will complete the arbitration process and provide HUD with 
all background information used during the arbitration and with a 
written, nonbinding recommendation as to which party or parties are 
responsible for the defect, and what corrective actions should be taken.
    (2) Unless an extension is granted for good cause by HUD, the 
arbitrator, within 21 days of the dispute resolution provider's receipt 
of the request for arbitration, will provide the parties with a copy of 
the nonbinding recommendation that was delivered to HUD, in accordance 
with Sec. 3288.40(h)(1).
    (i) Settlement offers. At any time before HUD issues a final order, 
the parties may submit to HUD a proposal to resolve the dispute.



Sec. 3288.45  HUD review and order.

    (a) Appropriate order. HUD will review the arbitrator's 
recommendation provided in accordance with Sec. 3288.40(h), any 
settlement offers presented by the parties in accordance with Sec. 
3288.40(i), and the information gathered during the arbitration, and 
will issue an appropriate order in which HUD may accept, modify, or 
reject the recommendations. HUD will forward a copy of the order to the 
arbitrator and to each of the parties and the homeowner, whether or not 
a party chose to participate in the arbitration.
    (b) Contents of order. If HUD finds that a defect exists, the order 
will include the following:
    (1) Assignment of responsibility for the correction and repair of 
all defects and associated costs; and
    (2) If the manufacturer, retailer, or installer is responsible for 
corrective action, a date by which the correction and repair of each 
defect must be completed, taking into consideration the seriousness of 
the defect.
    (c) Failure to comply. Failure to comply with an order issued by HUD 
is a violation of section 610(a)(5) of the Act (42 U.S.C. 5409(a)(5)).



        Subpart C_Alternative Process in HUD-Administered States



Sec. 3288.100  Scope and applicability.

    The requirements of this subpart C may be followed in lieu of the 
requirements of subpart B of this part to resolve disputes among 
manufacturers,

[[Page 275]]

retailers, and installers of manufactured homes in any state where 
subpart B of this part would otherwise apply. In limited circumstances, 
this subpart C permits manufacturers, retailers, and installers of 
manufactured homes to use neutrals of their choosing to resolve disputes 
concerning alleged defects in manufactured homes.



Sec. 3288.105  Time when Alternative Process is available.

    (a) The Alternative Process may be invoked after an alleged defect 
has been reported, pursuant to Sec. 3288.15(b). However, the 
Alternative Process may not be invoked more than 7 days after 
notification of a request for dispute resolution has been received by 
all of the parties. The notification must be delivered by overnight 
delivery, commercial carrier, or fax by the screening neutral, in 
accordance with Sec. 3288.30. If within 7 days of the receipt of 
notification, the Alternative Process is not initiated, the screening 
neutral will refer the matter to the mediator. Once the Alternative 
Process is invoked, neither the parties nor the homeowner may invoke the 
Mediation and Arbitration Process in the HUD Manufactured Home Dispute 
Resolution Program for 30 days.
    (b) No particular form or format is required to provide notification 
for the Alternative Process, but the party or parties submitting the 
notification must include a statement from the parties participating in 
the Alternative Process stating that the homeowner is not responsible 
for the alleged defect and that one or more of the parties will correct 
or repair the defect. All required agreements are set forth in Sec. 
3288.110 of this part. The parties must also make reasonable efforts to 
include the following information in the notification:
    (1) Identification of the case; and
    (2) Identification of the parties participating in the Alternative 
Process.
    (c) The screening neutral will notify the parties if the case is 
referred to the Alternative Process for resolution.



Sec. 3288.110  Alternative Process agreements.

    (a) Required agreement. To use the Alternative Process, the 
manufacturer, retailer, and installer of the manufactured home at issue, 
as appropriate, must agree:
    (1) That there is a defect in the manufactured home;
    (2) That the manufacturer, retailer, or installer is responsible for 
the defect;
    (3) That the homeowner is not responsible for the defect;
    (4) To engage a neutral to evaluate the dispute and make an 
assignment of responsibility for correction and repair; and
    (5) To notify the homeowner of, and allow the homeowner to be 
present at, any meetings and to inform the homeowner of the outcome.
    (b) Additional element of agreement. In addition, the parties should 
agree to act upon the neutral's assignment of responsibility for 
correction and repair.



  Subpart D_State Dispute Resolution Programs in Non-HUD Administered 
                                 States



Sec. 3288.200  Applicability.

    This subpart D establishes the minimum requirements that must be met 
by a state to implement its own dispute resolution program and therefore 
not be covered by the HUD Manufactured Home Dispute Resolution Program 
established in accordance with subpart B. The subpart also establishes 
the procedure for determining whether the state dispute resolution 
program meets the requirements of the Act for operating in lieu of the 
HUD Manufactured Home Dispute Resolution Program.



Sec. 3288.205  Minimum requirements.

    (a) List of requirements. The HUD Manufactured Home Dispute 
Resolution Program will not be implemented in any state that complies 
with the procedures of this subpart D and that has a dispute resolution 
program that provides for the following minimum requirements:
    (1) The timely resolution of disputes among manufacturers, 
retailers, or installers regarding responsibility for correction and 
repair of defects in manufactured homes;

[[Page 276]]

    (2) The issuance of appropriate orders for correction and repair of 
defects in such homes;
    (3) A coverage period for disputes that includes at least defects 
that are reported within 1 year after the date of first installation; 
and
    (4) Adequate funding and personnel.
    (b) Applicability to programs in state plans. (1) In order to 
include a dispute resolution program in a state plan that on February 8, 
2008 is fully or conditionally approved under Sec. 3282.302 of this 
chapter, a state must amend its state plan to provide for the 
requirements of paragraphs (a)(1) through (3) of this section.
    (2) After February 8, 2008, a state that submits a state plan for 
approval in accordance with Sec. 3282.302 of this chapter must provide 
for the requirements of paragraphs (a)(1) through (3) of this section in 
its state plan.



Sec. 3288.210  Acceptance and recertification process.

    (a) Submission of certification. A state seeking HUD acceptance of 
its state dispute resolution program under this subpart must submit to 
HUD a completed Dispute Resolution Certification Form, which is 
available by contacting HUD by telephone at (202) 708-6423 or by e-mail 
at [email protected]. The certification may be submitted as a part of, or 
independent of, a state plan under Sec. 3282.302 of this chapter. If 
included as part of a state plan, the state does not have to separately 
certify that it meets the requirements of Sec. 3288.205(a)(4).
    (b) HUD review and action. (1) HUD will review the Dispute 
Resolution Certification Form submitted by a state and may contact the 
state to request additional clarification or information as necessary. 
Upon completing its review, HUD will provide the state with notice of 
acceptance, conditional acceptance, or rejection of its dispute 
resolution program.
    (2) A notice of acceptance will include the date of acceptance.
    (3) If HUD rejects a state's dispute resolution program, HUD will 
provide an explanation of what is necessary to obtain full acceptance. A 
revised Dispute Resolution Certification Form may be submitted within 30 
days of receipt of such notification. If the revised Dispute Resolution 
Certification Form is inadequate or if the state fails to resubmit 
within the 30-day period or otherwise indicates that it does not intend 
to change its Dispute Resolution Certification Form, HUD will notify the 
state that its dispute resolution program is not accepted and that it 
has a right to a hearing on the rejection using the procedures set forth 
under subpart D of part 3282 of this chapter.
    (c) Conditional acceptance. A state meeting three of the four 
minimum requirements set forth under Sec. 3288.205(a)(1) through (4) 
will be conditionally accepted by HUD. If HUD conditionally accepts a 
state's dispute resolution program, HUD will provide an explanation of 
what is necessary to obtain full acceptance. A revised Dispute 
Resolution Certification Form may be submitted within 30 days of receipt 
of such notification. Any state conditionally accepted will be permitted 
to implement its own dispute resolution program for a period of not more 
than 3 years, absent extension of this period by HUD.
    (d) Revocation. If HUD becomes aware at any time that a state no 
longer meets the minimum requirements set forth under Sec. 3288.205, 
HUD may revoke acceptance of the state's certification after an 
opportunity for a hearing, using the procedures set forth under subpart 
D of part 3282.
    (e) Recertification of a program not included in state plan. Except 
as provided in paragraph (f), to maintain its accepted status, a state 
whose program is not included in an approved or conditionally approved 
state plan must submit a current Dispute Resolution Certification Form 
to HUD for review and acceptance as follows:
    (1) Every 3 years within 90 days of the day and month of the most 
recent date of HUD's acceptance of the state's program or
    (2) Whenever there is a significant change to the program.
    (f) Inclusion in state plan. If a state dispute resolution program 
is part of a state plan, it will be reviewed annually as part of the 
state plan and separate recertification of the state's dispute 
resolution program is not required.

[[Page 277]]



Sec. 3288.215  Effect on other manufactured home program requirements.

    A state with an accepted dispute resolution program will operate in 
lieu of HUD's Manufactured Home Dispute Resolution Program established 
under subpart B of this part 3288. A state dispute resolution program, 
even if it is an accepted dispute resolution program under this part, 
does not supersede the requirements applicable to any other aspect of 
HUD's manufactured home program. Any responsibilities, rights, and 
remedies applicable under the Manufactured Home Construction and Safety 
Standards in part 3280 of this chapter and the Manufactured Home 
Procedural and Enforcement Regulations in part 3282 of this chapter 
continue to apply as provided in those parts in all states.



       Subpart E_Dispute Resolution Program Rulemaking Procedures



Sec. 3288.300  Applicability.

    This subpart establishes special regulatory procedures for issuing 
or revising dispute resolution program regulations as codified in this 
part.



Sec. 3288.305  Consultation with the Manufactured Housing Consensus
Committee.

    HUD will seek input from the MHCC when revising the HUD Manufactured 
Home Dispute Resolution Program regulations in this part 3288. Before 
publication of a proposed rule to revise these regulations, HUD will 
provide the MHCC with an opportunity to comment on such revision. The 
MHCC may send to HUD any of the MHCC's own recommendations to adopt new 
dispute resolution program regulations or to modify or repeal any of the 
regulations in this part. Along with each recommendation, the MHCC must 
set forth pertinent data and arguments in support of the action sought. 
HUD will either: accept or modify the recommendation and publish it for 
public comment in accordance with section 553 of the Administrative 
Procedure Act (5 U.S.C. 553), along with an explanation of the reasons 
for any such modification; or reject the recommendation entirely, and 
provide to the MHCC a written explanation of the reasons for the 
rejection. This section does not supersede section 605 of the National 
Manufactured Housing Construction and Safety Standards Act of 1974 (42 
U.S.C. 5404).

regulate the course of the proceeding to avoid delay and to maintain 
order. If necessary to maintain order, the presiding official may 
exclude a witness or counsel from a proceeding. The Department may also 
take further action as permitted by statute.



Sec. 3800.50  Rights of witnesses in investigational proceedings.

    (a) Any person who testifies at a public investigational proceeding 
shall be entitled, on payment of costs, to purchase a copy of a 
transcript of the testimony the person provided.
    (b) In a nonpublic investigational proceeding, the presiding 
official may for good cause limit a witness to an inspection of the 
official transcript of that witness's testimony.
    (c) Any person subpoenaed to appear at an investigational proceeding 
may be represented by counsel as follows:
    (1) With respect to any question asked of a witness, a witness may 
obtain confidential advice from counsel;
    (2) If a witness refuses to answer a question, counsel for the 
witness may briefly state the legal grounds for the refusal;
    (3) Counsel for the witness may object to a question or a request 
for production of documents that is beyond the scope of the 
investigation or for which a privilege of the witness to refuse to 
answer may be invoked. In so doing, counsel for the witness may state 
briefly the grounds for the objection. Objections will be deemed 
continuing throughout the course of the proceeding. Repetitious or 
cumulative statements of an objection or the grounds for an objection 
are unnecessary and impermissible; and
    (4) After the Department's examination of a witness, counsel for the 
witness may request that the witness be permitted to clarify any answers 
to correct any ambiguity, equivocation, or incompleteness in the 
witness's testimony. The decision to grant or deny this request is 
within the sole discretion of the presiding official.



Sec. 3800.60  Settlements.

    (a) At any time during an investigation, the Department and the 
parties subject to an investigation may conduct settlement negotiations.
    (b) When the Secretary or Secretary's designee deems it appropriate, 
the Department may enter into a settlement agreement.

Sec. 4100.1  Functions and activities.

    (a) General statement. The Neighborhood Reinvestment Corporation 
(referred to in this part as the Corporation) was established by 
Congress in the Neighborhood Reinvestment Corporation Act (title VI of 
the Housing and Community Development Amendments of 1978, Pub. L. 95-
557, October 31, 1978). The Corporation is not a department, agency, or 
instrumentality of the Federal Government.
    (b) The Corporation is authorized to receive and expend Federal 
appropriations and other public and private revenues to conduct a 
variety of programs designed primarily to revitalize older urban 
neighborhoods by mobilizing public, private, and community resources at 
the neighborhood level. These programs include:
    (1) Neighborhood Housing Services. The major effort of the 
Corporation is to assist local communities in the development, expansion 
and provision of technical services to local Neighborhood Housing 
Services (NHS) programs. NHS programs are based upon partnerships of 
community residents, and representatives of local governments and 
financial institutions. Each local program is administered by an 
autonomous, private, non-profit corporation, and conducts a 
comprehensive revitalization effort in locally selected neighborhoods. 
Services to neighborhood residents include rehabilitation counseling, 
construction assistance, financial counseling, loan referrals and loans 
at flexible rates and terms to homeowners who do not meet private 
lending criteria. Programs and strategies to remove blighting 
influences, obtain improved public services and amenities, and improve 
the neighborhood's image and the functioning of its real estate market 
are also undertaken. To insure the continuing effectiveness of NHS 
programs, the Corporation provides grants, training, information and 
technical services to NHS programs.'
    (2) Mutual Housing Associations. The Corporation also supports the 
organizational development of, and provides technical assistance to, 
Mutual Housing Associations. Mutual Housing Associations are private, 
nonprofit organizations which own, manage and continually develop 
affordable housing. Mutual Housing residents are members of the 
Association which owns and manages their buildings; thus they enjoy the 
security of long-term housing tenure. Mutual Housing developments are 
capitalized through up-front grants and mortgages in a combination that 
ensures permanent affordability to low- and moderate-income families. 
Monthly housing charges to residents are kept at affordable levels on a 
continuing basis. A key element of Mutual Housing is the Association's 
commitment to use all resources in excess of operating and maintenance 
costs for the production of additional units. A Mutual Housing 
Association's board of directors includes current member-residents, 
potential residents, and representatives from the community, local 
government and business. Residents and community members make up the 
majority on the board. A highly qualified professional staff, employed 
by the Mutual Housing Association, carries out the day-to-day activities 
of the organization. In addition to creating new affordable housing 
opportunities, Mutual Housing Associations offer a creative alternative 
for subsidized rental housing developments whose subsidies are scheduled 
to expire.
    (3) Neighborhood preservation projects. The Corporation identifies, 
monitors, evaluates and supports through demonstration grants and 
technical assistance other promising neighborhood preservation 
strategies based on local, public-private partnerships.

[[Page 284]]

    (4) Programmatic supplements. Proven, replicable programmatic tools 
are offered as broadly as resources permit. Often, these selected 
strategies are supported by Neighborhood Reinvestment grants. The 
Corporation's major programmatic supplements include the following:
    (i) Neighborhood economic development and commercial revitalization 
strategies. The Corporation's neighborhood economic development and 
commercial revitalization strategies offer NHSs a variety of tools 
designed to stabilize and enhance the economic base of NHS 
neighborhoods. They complement NHSs' revitalization mission by focusing 
the energies and resources of the partnership on the economic issues 
underlying neighborhood decline. Neighborhood economic development and 
commercial revitalization assures a viable neighborhood economy by 
strengthening small businesses and improving the physical environment of 
the area, thus providing additional goods, services, and employment 
opportunities for the community.
    (ii) Housing Development Strategies. The Corporation's Housing 
Development Strategies program addresses the shortage of affordable, 
quality housing available to low to moderate income families in NHS 
neighborhoods, as well as the blighting effect of vacant lots and 
substandard properties. Home ownership opportunities are created through 
the planning and implementation of a variety of housing mechanisms by 
the NHS, which are intended to reverse negative real estate market 
trends, enhance new residential growth, and create renewed neighborhood 
pride. The mechanisms being used to achieve these goals include the 
following.
    (A) The Owner Built Housing program is a supervised housing 
construction process that helps moderate-income homeowners to 
collectively build their own homes. The NHS provides technical 
assistance while private lenders and public bodies providing financing.
    (B) The Owner Rehab Housing program assists low to moderate income 
families in collectively rehabilitating existing blighted and vacant 
structures.
    (C) The Infill Housing program provides a mechanism for assisting 
NHSs in building new units on vacant land to meet the needs of 
prospective lower income homeowners.
    (D) The Urban Subdivisions program focuses on providing low cost, 
new housing for low-to-moderate income families on tracts of land 
suitable for the construction of 20 or more units.
    (iii) Problem properties strategies. This program assists NHSs in 
addressing specific problem areas beyond the scope of basic NHS services 
and typical financial resources. Through the implementation of various 
problem properties strategies, NHS programs are able to assist tenants 
to purchase, improve the physical condition of target blocks, eliminate 
vacant neighborhood eyesores, develop housing and service facilities for 
special populations, and stimulate private reinvestment and new 
conventional mortgages in the NHS community.
    (5) Apartment Improvement Program. The goal of the Apartment 
Improvement Program is to provide an effective, economical means of 
revitalizing and preserving neighborhoods with multi-family housing for 
the benefit of the current residents. The program is based upon a 
partnership of tenants and community representatives, property owners 
and managers, financial institutions and local government. The program 
assists in the development of an individually tailored improvement plan 
of activities from which each building may benefit, including tenant 
participation, tax assessment reviews, and increased investment or 
restructured mortgages to improve the economic viability of the 
buildings and to finance improvements.
    (6) Neighborhood Housing Services of America. The Corporation also 
supports Neighborhood Housing Services of America (NHSA), an 
independent, private, non-profit corporation which provides a variety of 
services to local NHS programs, including a secondary market for NHS 
revolving loan fund loans, and the strengthening of private sector 
resources available to the network of local NHSs.

Sec. 4100.2  General organization.

    (a) The Board of Directors. (1) The Corporation is under the 
direction of a Board of Directors composed of six members: the Chairman 
of the Federal Home Loan Bank Board or a member of the Federal Home Loan 
Bank Board designated by the Chairman; the Secretary of Housing and 
Urban Development; the Chairman of the Board of Governors of the Federal 
Reserve System, or a member of the Board of Governors of the Federal 
Reserve System designated by the Chairman; the Chairman of the Federal 
Deposit Insurance Corporation or the appointive member of the Board of 
Directors of the Federal Deposit Insurance Corporation if so designated 
by the Chairman; the Comptroller of the Currency; and the Chairman of 
the National Credit Union Administration, or a member of the Board of 
the National Credit Union Administration designated by the Chairman. 
Members of the Board serve without additional compensation. The Board 
elects from among its members a Chairman and Vice-Chairman. The Bylaws 
of the Corporation provide for the creation of an Audit Committee, and 
such other committees as the Board may from time to time establish.
    (2) The Board holds an Annual Meeting each year during the month of 
May (or as the Bylaws or the Board may specify). The Board also holds 
regular meetings at least quarterly and special meetings as required. 
The meetings of the Board are conducted in accordance with provisions of 
the Neighborhood Reinvestment Corporation Act, the Government in the 
Sunshine Act (5 U.S.C. 552b), the Corporation's Bylaws, and when not 
inconsistent with the foregoing, with Robert's Rules of Order. Every 
portion of every meeting of the Board is open to public observation 
except as provided by the Government in the Sunshine Act. Interested 
members of the public may attend such meetings, but may not participate 
therein unless invited or permitted to do so by the Board.
    (3) The Secretary of the Corporation, in consultation with the 
Corporation's General Counsel, is responsible for taking such steps as 
are required to ensure the Corporation's compliance with the Government 
in the Sunshine Act, as that Act may be amended from time to time. 
Consistent with this responsibility, the Secretary of the Corporation 
provides to the Communications Department at the principal office of the 
Corporation such records as the Act requires to be made available to the 
public for access during regular office hours on regular business days.
    (b) The Officers. (1) The officers of the Corporation are the 
Executive Director, the Deputy Executive Director, the Secretary, the 
Treasurer, and such other officer positions as the Board may, in 
consultation with the Executive Director, create. The Board elects the 
officers of the Corporation annually.
    (2) The Neighborhood Reinvestment Corporation Act provides that the 
Executive Director shall serve as the chief executive officer of the 
Corporation. Consistent with that authority, the Corporation's Bylaws 
provide that the Executive Director shall have the responsibility and 
authority for the day-to-day administration of the affairs of the 
Corporation under the general supervision of the Board. The Board 
periodically reviews the activities of the Executive Director and, from 
time to time, provides guidance and policy direction to the Executive 
Director in the exercise of his or her authority.
    (3) The responsibilities and authorities of the other officers of 
the Corporation are set forth in the Corporation's Bylaws, resolutions 
and policies adopted by the Board, duties and authorities delegated to 
each officer, other statutes and this statement. (See, for example, the 
Government in the Sunshine Act and paragraph (a)(3) of this section for 
specific duties of the Secretary and General Counsel.)
    (c) Principal office. The Corporation maintains its principal office 
in the District of Columbia. Currently, the principal office is 
maintained at 1325 G Street NW., Suite 800, Washington, DC 20005.

[49 FR 12700, Mar. 30, 1984, as amended at 54 FR 13062, Mar. 30, 1989]



Sec. 4100.3  Field activities.

    The Corporation conducts its field activities from district and 
field offices around the country. District offices

[[Page 286]]

provide coordination of field activities in support of local programs 
within the geographic limits of each district. Field offices within each 
district provide assistance in the development and support of local 
programs. A current directory of all district and field offices can be 
obtained upon request from the Communications Department, Neighborhood 
Reinvestment Corporation, 1325 G Street NW., Suite 800, Washington, DC 
20005.

[49 FR 12700, Mar. 30, 1984, as amended at 54 FR 13061, Mar. 30, 1989]



Sec. 4100.4  Inquiries.

    (a) General. All requests for information, forms, and records should 
be addressed to: Communications Department, Neighborhood Reinvestment 
Corporation, 1325 G Street NW., Suite 800, Washington, DC 20005.
    (b) Applications. Applications for the Corporation's assistance in 
the development of NHS programs and complementary programs and 
strategies, or the support of other promising neighborhood strategies 
are accepted on an ongoing basis. Local governmental or nonprofit 
entities should submit completed applications (forms are available upon 
request), including supportive materials, to the Corporation at the 
address stated in paragraph (a) of this section. The Corporation reviews 
applications to determine their readiness for development or support. 
Promising applications are selected for field reviews. Subject to the 
availability of the Corporation's resources, the Corporation may enter 
into agreements with top ranking applicants to provide financial and 
technical assistance in the development or support of selected programs. 
The application form contains a list of the criteria used for 
determining the readiness and promise of applications.
    (c) Records. (1) The Corporation maintains such records and 
information for public inspection and copying as are required by the 
Freedom of Information Act (5 U.S.C. 552), as that Act may be amended 
from time to time. Records are available for public inspection and 
copying during regular business hours on regular business days at the 
address stated in paragraph (a) of this section. Requests for records 
should be submitted in writing and state the full name and address of 
the person requesting the records and a description of the records or 
other information sought that is reasonably sufficient to permit their 
identification without undue difficulty. A request should be submitted 
sufficiently in advance of the date inspection or copying is desired, 
preferably by mail.
    (2) Although the Corporation finds that the publication of indexes 
of statements of policy and interpretations or administrative staff 
manuals and instructions would be unnecessary and impracticable, such 
information will be made available upon request.
    (d) Fees for providing copies for records. Fees shall be assessed 
pursuant to the Freedom of Information Act (5 U.S.C. 552) in order to 
recover the full allowable direct costs of providing copies of records. 
For purposes of this section, the term direct costs means those 
expenditures which the Corporation actually incurs in searching for and 
duplicating (and in the case of commercial use requesters, reviewing) 
documents to respond to a Freedom of Information Act (``FOIA'') request. 
Direct costs include, for example, the salaries of the employees 
performing the work (the basic rate of pay plus 16 percent of that rate 
to cover benefits) and the cost of operating duplicating equipment. The 
term search includes all time spent looking for material that is 
responsive to a request, including page-by-page or line-by-line 
identification of material within documents. Searches may be done 
manually or by computer using existing programming. The term duplication 
refers to the process of making a copy of a document necessary to 
respond to a FOIA request. Such copies can take the form of paper copy, 
microfilm, audiovisual materials, or machine readable documentation 
(e.g., magnetic tape or disk), among others. The term review refers to 
the process of examining documents located in response to a commercial 
use request to determine whether any portion of any document is 
permitted to be withheld. It also includes processing any documents for 
disclosure, e.g., doing all that is necessary to exise them and 
otherwise prepare them for release. Review does not include time spent 
resolving general

[[Page 287]]

legal or policy issues regarding the application of exemptions. A 
schedule based on these principles is set forth in paragraph (d)(9) of 
this section.
    (1) Categories of requesters. Fees will be assessed according to the 
category of the requester. There are four categories:
    (i) Commercial use requesters. For purposes of this section, the 
term commercial use request refers to a request from or on behalf of one 
who seeks information for a use or purpose that furthers the commercial, 
trade, or profit interests of the requester or the person on whose 
behalf the request is made. In determining whether a requester properly 
belongs in this category, the Corporation will look to the use to which 
the requester will put the documents requested. If the use is not clear 
from the request itself, or if there is reasonable cause to doubt the 
requester's stated use, the Corporation shall seek additional 
clarification before assigning the request to a specific category.
    (ii) Educational and noncommercial scientific institution 
requesters. For purposes of this section, the term educational 
institution refers to a preschool, a public or private elementary or 
secondary school, an institution of graduate higher education, an 
institution of undergraduate higher education, an institution of 
professional education, or an institution of vocational education, which 
operates a program or programs of scholarly research. The term 
noncommercial scientific institution refers to an institution that is 
not operated on a commercial basis, as that term is used in paragraph 
(d)(1)(i) of this section, and which is operated solely for the purpose 
of conducting scientific research the results of which are not intended 
to promote any particular product or industry. To be eligible for 
inclusion in this category, requesters must show that the request is 
made as authorized by and under the auspices of a qualifying 
institution, and that the records are not sought for a commercial use, 
but are sought in furtherance of scholarly (if the request is from an 
educational institution) or scientific (if the request is from a 
noncommercial scientific institution) research.
    (iii) Requesters who are representatives of the news media. For 
purposes of this section, the term representative of the news media 
refers to any person actively gathering information for an entity that 
is organized and operated to publish or broadcast news to the public. 
Examples of news media entities include television or radio stations 
broadcasting to the public at large, and publishers of periodicals (but 
only in those instances when they can qualify as disseminators of news) 
who make their products available for purchase or subscription by the 
general public. These examples are not intended to be all-inclusive. In 
the case of freelance journalists, they may be regarded as working for a 
news organization if they demonstrate a solid basis for expecting 
publication through that organization, even though not actually employed 
by it. A publication contract would be the clearest proof, but the 
Corporation may also look at the past publication record of a requester 
in making this determination. To be eligible for inclusion in this 
category, a requester must meet the criteria above, and his or her 
request must not be made for a commerical use. In reference to this 
class of requester, a request for records supporting the news 
dissemination function of the requester shall not be considered to be a 
request that is for a commercial use.
    (iv) All other requesters.
    (2) Limitations on fees to be charged--(i) Commercial use 
requesters. Commercial use requesters shall be assessed the full direct 
costs for searching for, reviewing, and duplicating records, in 
accordance with the fee schedule at paragraph (d)(9) of this section. 
Commercial use requesters are not entitled to the free search time or 
free pages of duplication provided to other categories of requesters.
    (ii) Educational and noncommercial scientific institution 
requesters. Requesters in this category may be assessed fees only for 
duplication of records in excess of the first 100 pages. Requesters in 
this category may not be assessed fees for search or review.
    (iii) Requesters who are representatives of the news media. 
Requesters in this category may be assessed fees only for duplication of 
records in excess of the

[[Page 288]]

first 100 pages. Requesters in this category may not be assessed fees 
for research or review.
    (iv) All other requesters. Requesters who do not fit into any of the 
categories above shall be assessed fees only for searching and 
duplicating records, except that the first 100 pages of duplication and 
the first two hours of search time shall be furnished without charge. 
Requesters in this category may not be assessed fees for review.
    (v) Review of records. Charges will be assessed only for the initial 
review of the located documents and not for time spent at the 
administrative appeal level on an exemption applied at the initial 
determination level. However, where records or portions of records are 
withheld in full under an exemption which is subsequently determined not 
to apply, and these records are reviewed again to determine the 
applicability of other exemptions not previously considered, charges for 
review are properly assessable.
    (vi) Additional copies. The Corporation will normally furnish only 
one copy of any record. The allowance of 100 free pages of duplication 
under paragraphs (d)(2) (ii), (iii), and (iv) of this section shall not 
apply to additional copies furnished at the request of the record 
requester. Full duplication fees shall be assessed for each page of each 
such additional copy.
    (3) Charges for unsuccessful search. Where applicable under 
paragraph (d)(2) of this section search fees may be assessed for time 
spent searching, even if the Corporation fails to locate the records or 
if records located are determined to be exempt from disclosure.
    (4) Notice of anticipated fees in excess of $25.00. Unless the 
person making the request states in his or her initial request that he 
or she will pay all costs regardless of amount, the Corporation will 
notify him or her as soon as possible if there is reason to believe that 
the cost for obtaining access to and/or copies of such records will 
exceed $25. If such notice is given, the time limitations contained in 
the Freedom of Information Act shall not commence until the person 
making the intitial request agrees in writing to pay such cost.
    (5) Advance payments. The Communications Director is authorized to 
require an advance payment of an amount up to the full estimated charges 
whenever he or she determines that:
    (i) The allowable charges that a requester may be required to pay 
are likely to exceed $250 and the requester has no history of payment 
and cannot provide satisfactory assurance that payment will be made; or
    (ii) A requester has previously failed to pay a fee charged in a 
timely manner.

If such a payment is required, the time limitations contained in the 
Freedom of Information Act shall not commence until payment is made.
    (6) Charging interest. The Corporation will assess interest charges 
on any unpaid fees starting on the 31st day following the day on which 
the billing for fees was sent to the requester. Interest will be at the 
rate prescribed in 31 U.S.C. 3717 and will accrue from the date of the 
billing. Receipt of the fee by the Corporation, even if not processed, 
will stay the accrual of interest. Interest is not chargeable for unpaid 
advance payments under paragraph (d)(5) of this section.
    (7) Aggregating requests. A requester may not file multiple requests 
at the same time, each seeking portions of the document or documents, 
solely in order to avoid payment of fees. When the Corporation 
reasonably believes that a requester, or a group of requesters acting in 
concert, is attempting to break a request down into a series of requests 
for the purpose of evading the assessment of fees, the Corporation may 
aggregate any such requests and charge accordingly.
    (8) Waiver or reduction of fee. The Corporation will furnish 
documents without charge or at a reduced charge when it is determined 
that disclosure of the information is in the public interest because it 
is likely to contribute significantly to public understanding of the 
operations or activities of the Corporation and is not primarily in the 
commercial interest of the requester. In making a request for a waiver 
or reduction of fees, a requester should include a clear statement of 
his or her interest in the requested documents: The

[[Page 289]]

proposed use for the documents and whether the requester will derive 
income or other benefit from such use; and a statement of how the public 
will benefit from such use. Determinations concerning waiver or 
reduction of fees shall be made by the Executive Director, or his or her 
designee.
    (9) Schedule of fees. Fees for searching for, reviewing, 
duplicating, and providing records and information of the Corporation 
under this section will be assessed in accordance with the following 
schedule:
    (i) Manual search. For each quarter hour or fraction thereof: $3.37.
    (ii) Computer search. For each quarter hour or fraction thereof: 
$3.37.
    (iii) Review. For each quarter hour or fraction thereof: $4.87.
    (iv) Duplication.
    (A) For a paper photocopy of an existing paper record, $.10 per 
page.
    (B) For duplication of records other than existing paper records 
(such as computer-stored information, audio or video tapes, microfiche 
or microfilm), the fee shall equal the actual direct cost of production 
and duplication of the records or information in a form that is 
reasonably usable by the requester.
    (10) Processing costs. The Communications Director will waive 
payment in instances in which the costs of routine collection and 
processing of the fee are likely to equal or exceed the amount of the 
fee.
