Manufactured Home Construction and Safety Standards
AGENCY: Office of the Assistant Secretary for Housing--Federal Housing
Commissioner, HUD.
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: This proposed rule would amend the Federal Manufactured Home
Construction and Safety Standards (the Construction and Safety
Standards) by adopting the fourth and fifth group of recommendations
made to HUD by the Manufactured Housing Consensus Committee (MHCC).
This rule would also amend the Manufactured Home Procedural and
Enforcement Regulations, the Model Manufactured Home Installation
Standards and the Manufactured Home Installation Program regulations.
The National Manufactured Housing Construction and Safety Standards Act
of 1974 (the Act), as amended by the Manufactured Housing Improvement
Act of 2000, requires HUD to publish in the Federal Register any
proposed revised Construction and Safety Standard submitted by the
MHCC. The MHCC has prepared and submitted to HUD its fourth and fifth
groups of recommendations to improve various aspects of the
Construction and Safety Standards. HUD has reviewed those proposals and
has made a number of editorial revisions to them. These recommendations
are being published to provide notice of the proposed revisions and an
opportunity for public comment.

SUPPLEMENTARY INFORMATION:
I. Background
The National Manufactured Housing Construction and Safety Standards
Act of 1974 (42 U.S.C. 5401-5426) (the Act) authorizes HUD to establish
and amend the Federal Manufactured Home Construction and Safety
Standards (the Construction and Safety Standards or MHCSS) codified in
title 24 of the Code of Federal Regulations (CFR), part 3280. The Act
was amended by the Manufactured Housing Improvement Act of 2000 (Pub.
L. 106-569, Approved December 27, 2000) which expanded the purposes of
the Act, created the Manufactured Housing Consensus Committee (MHCC), a
consensus committee responsible for providing HUD recommendations to
adopt, revise and interpret HUD's Construction and Safety Standards,
and established the MHCC and regulatory development process. HUD's
Construction and Safety Standards only apply to the design,
construction, and installation of new manufactured homes.
The MHCC held its first meeting in August of 2002 and began work on
reviewing possible revisions to the Construction and Safety Standards.
The MHCC developed its own priorities for preparing proposed revisions
for HUD to consider. As the MHCC proceeded, proposed revisions to the
Construction and Safety Standards were divided into sets.
This proposed rule is based on the fourth and fifth sets of MHCC
recommendations to improve various aspects of the Construction and
Safety Standards. HUD reviewed those recommendations submitted by the
MHCC and adopted them after making editorial revisions and some
additions. The following is a discussion of the specific revisions to
the Construction and Safety Standards that are included in this
proposed rule.
II. Proposed Changes
The proposed rule would revise 24 CFR part 3280, the Construction
and Safety Standards, and would also revise the incorporated by
reference standards, where indicated. It also proposes revisions to
HUD's Procedural and Enforcement Regulations (24 CFR part 3282), Model
Manufactured Home Installation Standards (24 CFR part 3285), and
Manufactured Home
[[Page 43115]]
Installation Program (24 CFR part 3286). Many of the proposed changes
would codify existing building practices or conform HUD standards to
other existing residential building codes. As identified in the summary
table below, HUD has identified eight (8) standards in this proposed
rule that would have an economic impact on the production costs of
manufactured homes: changes to allowed moisture content of treated
lumber, modifications to the temperature ratings for air ducts, adding
a requirement for the water resistive barrier, modifications to kitchen
cabinet fire protection, changes to the maximum distance from the
fixture trap to vent, under-chassis line-voltage wiring protection,
updated reference standards allowing reduced design values for certain
lumber, and modifications to structural design requirements for attics.
HUD is requesting comment whether any of the other proposed changes
would have an economic impact or impose additional costs on the
production of manufactured housing, specifically on the analysis
supporting this proposed rule and the assumptions used.

BILLING CODE 4210-67-C
The following is a discussion of the specific revisions to the
Construction and Safety Standards that are proposed by this rule.
A. General Update of the Standards and New Standards Incorporated by
Reference
HUD proposes to revise the definitions for ``Certification label''
and ``Dwelling unit'' in Sec. 3280.2 to correct references and clarify
the criteria for defining dwelling units. HUD proposes to add
additional definitions for ``Dwelling,'' ``Multipurpose fire sprinkler
system,'' ``Stand-alone fire sprinkler system,'' and ``Water resistive
barrier'' to further clarify terms regarding standards revisions and
standards incorporated by reference that are recommended by the MHCC.
A significant goal of this proposed rule is to update standards
incorporated by reference under Sec. 3280.4 to align the regulations
at 24 CFR part 3280 to more current building codes and practices. As a
result, this rule proposes to revise 70 current standards, add 16 new
standards, and incorporate by reference 2 standards in a new location,
for a total of 88 standards, under Sec. 3280.4 (see Table 2 for more
detail and information). Notable changes to the reference standards
being added or revised are updated references for unitary air-
conditioning and air-source heat pump equipment (NSI/AHRI Standard 210/
240-2008 with Addenda 1 and 2); gas fired central furnaces (ANSI
Z21.47); heating and cooling equipment and systems (UL 1995); and
safety of household and electronic appliances (UL 60335-2-34). New
standards will allow for the use of more modern gas-fired appliances,
such as tankless water heaters (ANSI Z21.10.3) and will eliminate the
need for Alternative Construction (AC) letters in some cases. Many
paragraphs within Sec. 3280.4 are unchanged in content but are being
revised to reflect a redesignated outline structure.
HUD also proposes to amend Sec. 3280.5 to provide for multi-
dwelling unit manufactured homes and reinforce the requirement for each
manufactured home dwelling unit to bear a data plate and to include an
updated statement on the Wind Zone Map that references an updated ASCE/
SEI 7-05 standard for the anchoring and foundation system of the unit.
Consistent with a 2015 determination made by the MHCC, HUD is proposing
a maximum of three dwelling units for a multi-dwelling unit
manufactured home. The MHCC based its determination on ensuring
consistency with a similar state code. HUD is interested in public
comment specific to this maximum provision for three dwelling units,
including benefits and challenges if a four unit maximum were
considered and how any conflict with differing state maximums would be
handled. HUD is also making a conforming change to Sec. 3282.8, by
removing paragraph (l).
B. Planning Considerations
The proposed rule would amend Sec. 3280.102 to add definitions for
``Air, exhaust,'' ``Air, outdoor,'' ``Exhaust system,'' ``Mechanical
ventilation,'' ``Natural ventilation,'' ``Supply system,'' and
``Ventilation''. The proposed rule would clarify the terminology
utilized for outlining the airflow and mechanical
[[Page 43120]]
ventilation system requirements for a manufactured home, which is
described in the proposed paragraph changes under Sec. 3280.103. The
proposed changes would specify the allowance for local exhaust systems
to be utilized in kitchens and bathrooms and clarify the distance
requirement for range and cooktop exhaust systems to be located at no
more than three (3) feet apart. HUD also is proposing to add
clarifications regarding the airflow rating that should be utilized for
design of a home, provided that duct sizing meets either prescriptive
ANSI/ASHRAE standards or the ventilation system manufacturer's design
criteria. The proposed changes would also make editorial revisions to
Sec. Sec. 3280.103, 3280.105, 3280.109 and 3280.115, accommodating
design for multi-dwelling unit manufactured homes.
The proposed rule would amend the provisions for exit doors in
Sec. 3280.105 to accommodate open floorplans, update exterior door
size requirements and would, in Sec. 3280.112, establish a 30-inch
minimum hallway size requirement for homes 14 feet in inside width or
larger.
The proposed rule would amend Sec. 3280.113 to reflect more
current ANSI standards (ANSI Z97.1-2009) for safety glazing materials
and establish new soundproofing requirements for multi-dwelling unit
manufactured homes in a new section 3280.115.
C. Fire Safety
HUD is proposing to amend Sec. 3280.203 to clarify that non-
horizontal surfaces above the horizontal plane formed by the bottom of
the range hood are not considered to be exposed surfaces subject to
fire protective requirements. In Sec. 3280.204, the proposed rule
would also clarify the requirements for finish materials used in range
hoods and establish a fire spread rating. The proposed rule is needed
to ensure that the use of decorative range hood covers meet the fire
safety standards in the Construction and Safety Standards. It is more
stringent than model codes for site-built one-to-four single family
housing, which contains no such requirement.
HUD is proposing to expand the fire safety subpart to include
guidelines and requirements for the design and installation of fire
sprinkler systems when a manufacturer chooses to install such a system
as outlined in Sec. 3280.214. While this proposed rule is not adding a
requirement that fire sprinkler systems be installed, when a
manufacturer installs a fire sprinkler system, this section would
establish the requirements for the installation of the fire sprinkler
system in a manufactured home. This section would apply to both stand-
alone and multipurpose fire sprinkler systems that do not include the
use of antifreeze. A back-flow preventer is not required to separate a
stand-alone sprinkler system from the home's water distribution system.
The proposed rule would establish minimum requirements for the
design of a fire sprinkler system itself to be in accordance with NFPA
13D (proposed for incorporation by reference in proposed Sec. 3280.4)
or equivalent. The proposed rule would outline required sprinkler
locations, excepting specific areas within a manufactured home,
temperature ratings and separation from heat sources, installation
requirements for freezing conditions, and the maximum areas of coverage
for a single sprinkler head. The proposed rule would also establish
requirements for installation practices, piping support and sizing
standards to achieve minimum pressure requirements, shutoff valves,
drainage, minimum flow, design flow rates, and operational testing. The
proposed rule would also require the manufacturer to permanently affix
a Fire Sprinkler System Certificate adjacent to the data plate and
specify on the Fire Sprinkler System Certificate the minimum required
pressure in pounds per square inch (psi) and flow rate for the water
supply system. This proposal was not specifically recommended by the
MHCC but added by HUD to support the addition of the requirements
proposed for multi-dwelling unit manufactured homes.
Per MHCC recommendations, HUD is also proposing to add new fire
safety requirements for multi-dwelling unit manufactured homes in Sec.
3280.215. In manufactured homes with more than one dwelling unit, each
dwelling unit must be separated from each other by wall and floor
assemblies having not less than a 1-hour fire resistance rating when
tested in accordance with Chapter 16 of the National Design
Specification for Wood Construction, NDS-2015, the standards proposed
to be incorporated by reference under Sec. 3280.4. The proposed rule
would outline requirements for fire-resistant floor/ceiling and wall
assemblies and the fire resistance rating of supporting construction of
such assemblies. Penetrations of wall or floor-ceiling assemblies in
multi-dwelling unit manufactured homes are required to be fire-
resistance rated in accordance with MHCC recommendations specified in
the proposed standards under Sec. 3280.215.
HUD is also including in this proposed rule a new section under
Sec. 3280.216 outlining draftstopping requirements, as recommended by
the MHCC, for multi-dwelling unit manufactured homes. Draftstopping
standards for single dwelling unit manufactured homes were previously
recommended by MHCC but were not included in the prior rulemaking that
addressed the MHCC 3rd set of recommendations (86 FR 2496, January 12,
2021) due to cost impacts and will be added to the agenda of future
MHCC consideration, as discussed in the proposed rule for the prior
rulemaking (85 FR 5589, 5594, January 31, 2020). This proposed rule
would apply them to the multi-dwelling unit manufactured homes,
however, since multi-dwelling units contain numerous kitchens,
furnaces, and other causes of residential fires, it inherently has a
greater risk and containment is essential for safety of the occupants.
This proposal is not expected to add additional costs beyond those
already incurred in the normal design and construction process for
multi-dwelling unit manufactured homes.
D. Body and Frame Requirements
The proposed rule would amend Sec. 3280.303 to reflect that all
construction methods used in the construction process for manufactured
homes must conform not only to accepted engineering practices, but to
an approved quality assurance manual as required by Sec. Sec. 3282.203
and 3282.361(c), to ensure durable, livable, and safe housing. This
proposal underscores the importance and HUD prioritization of ensuring
compliance with effective quality assurance standards to enhance and
improve the construction process and quality of manufactured homes.
The proposed rule would amend Sec. 3280.304 to update the
reference standards and specifications for steel, wood and wood
products, unclassified materials, and fasteners to allow manufacturers
and designers to use more recent publications and align the MHCSS with
more current industry standards.
HUD is also proposing to amend language under Sec. 3280.305 to
update the reference for design wind pressures for Exposure C from ASCE
7-88 to ASCE/SEI 7-05 that is to be specified based on the Basic Wind
Zone Map for Manufactured Housing, which can be used as an alternate
option to design homes in lieu of using the Table of Design Wind
Pressures found in Sec. 3280.305. In the MHCC recommendations to HUD,
the
[[Page 43121]]
committee recommended that the wind pressures included in the Table of
Design Wind Pressures remain unchanged, but requested that ``HUD staff
work to update the wind speeds references'' that are used to design
manufactured homes in Wind Zones II and III.
As requested, HUD staff completed a general comparison of ASCE 7-88
and ASCE 7-05 followed by an in-depth analysis to determine the
appropriate wind speeds for Wind Zones II and III that would best align
and correlate with wind pressures in the Table of Design Wind
Pressures. As a general introduction, historical references to wind
speed within the MHCSS are based on ``fastest mile'' wind speed
measurements. These fastest mile wind speeds are currently 100 miles
per hour (mph) for Wind Zone II and 110 mph for Wind Zone III. Fastest
mile means the average speed at which an airborne particle would travel
a mile in the direction of the wind, in mph. However, most wind
professionals today, including ASCE, now use a peak three-second gust
wind speed to define wind loads, which is the highest average speed
measured over a three second period of time, in mph. It is important to
understand this change in both wind speed measurement and terminology
when assessing the new wind speed references in this proposed rule.
In addition to the ASCE 7 update for wind speed measurement from
``fastest mile'' to ``three-second gust,'' ASCE updated the
mathematical formulas used to determine the wind pressures and the wind
speeds in hurricane-prone areas. This review led to the in-depth
analysis below and the revised wind speeds included in this proposed
rule.
HUD performed two different methods to determine revised wind
speeds. The first was to review the HUD wind speed/zone map with the
wind speed map in ASCE 7-05, to verify that a manufactured home would
be subject to comparable wind speeds if designed using ASCE 7-05. The
second used the prescriptive wind pressures shown in the Table of
Design Wind Pressures under Sec. 3280.305 as a baseline to perform a
series of iterative calculations to determine wind speeds that would
produce similar wind pressures for Wind Zones II and III.
The first analysis consisted of overlaying the contour lines for
Wind Zones II and III on top of the wind speed map published in ASCE 7-
05 to verify that manufactured homes would be designed for wind speeds
that are comparable to the requirements of ASCE 7-05. Using this
method, the maximum wind speed identified in ASCE 7-05 for the
continental United States of America is 150 mph. The only other
location ASCE 7-05 indicates a wind speed above 150 mph is Guam, which
requires a wind speed of 170 mph. Setting 150 mph as the upper bound
(Wind Zone III) resulted in reviewing the locations between Wind Zones
II and III compared to the those in ASCE 7-05. It was found that there
are multiple wind speeds between the ASCE 7-05 contours lines ranging
from 100 mph to a maximum of 140 mph. Therefore, since the HUD wind
zones encompass multiple wind speeds and the HUD wind zones must be
appropriate for all homes within these limits, Wind Zone II was set to
a wind speed of 140 mph. Based off this analysis, HUD staff determined
the revised wind speeds for Wind Zones II and III should be 140 mph and
150 mph, respectively, based off a three-second gust.
HUD's second analysis used the Durst Curve found in the commentary
of ASCE 7 to convert the fastest mile to three-second gust and compare
it to the International Building Code's (IBC) equation of Vfm= (V3sec-
10.5)/1.05 (IBC Section 1609.3). Both conversions resulted in wind
speeds for Wind Zones II and III increasing from 100 mph and 110 mph,
to 120 mph and 130 mph, respectively. However, these conversions could
not be used alone as they do not factor in changes ASCE 7 made
throughout the years to determine the wind pressures for building
design that are now based on wind speed. The following paragraphs
describe the main differences between the 1988 and 2005 editions of the
ASCE 7 code.
ASCE 7-88 and ASCE 7-05 use the following wind pressure
(P) equation P = q*Gh*Cp-qh(GCpi) (eq. 1)
ASCE 7-88's velocity pressure (q/qh) is equal to: q/qh =
0.00256*Kz*(I*V)2 (eq. 2) where V is fastest mile wind speed, I = 1.05
for areas 100 miles from coast, Kz = 0.8, Gh = 1.32 and GCpi = +/-0.25
ASCE 7-05's velocity pressure (q/qh) is equal to: q/qh =
0.00256*Kz*Kzt*Kd*I*V2 (eq. 3) where V is 3 second gust wind speed, I =
1.0, Kz = 0.85, G = 0.85, GCpi = +/- 0.18, Kzt = 1, Kd = 0.85
Using the above equations and keeping V constant, equation 2 and 3
above would simplify to q=0.00226*V2 and q=0.00185*V2 for ASCE 7-88 and
ASCE 7-05 respectively, which results is an 18 percent decrease in
pressure from ASCE 7-88 to ASCE 7-05. Using these values for ``q'' and
plugging them into the first equation, the design wind pressure (P)
would be decreased even further. The overall wind design pressure would
be decreased 47 percent if the wind speeds currently published in the
MHCSS were left unrevised yet the design option was updated to ASCE 7-
05.
HUD conducted an iterative analysis to match the prescriptive wind
pressures shown in the Table of Design Wind Pressure to wind pressures
using the ASCE 7-05 simplified method, also known as Method 1. The
prescriptive Main Wind Force Resisting System (MWFRS) wind pressures
are 39 pounds per square foot (psf) and 47 psf for Wind Zones II and
III, respectively. Using ASCE 7 Method 1, winds speeds could be
approximately 145 mph for Zone II and 160 mph for Zone III. However,
based on the first analysis, it was determined that wind speeds of 140
mph and 150 mph for Zones II and III would keep manufactured housing on
par with design of other single-family structures. Finally, wind speeds
of 140 mph and 150 mph were used to compare the prescriptive component
and cladding wind pressures in Sec. 3280.305 to ASCE 7-05, which
resulted in approximately the same wind pressures depending on the
tributary area used. Based on these thorough analyses, HUD is proposing
to update the wind speeds for Wind Zones II and III to 140 mph and 150
mph, respectively, based upon a three-second gust.
HUD also proposes to update the isotach reference under Sec.
3280.305(c)(2)(iii)(A) for Wind Zone III in the State of Alaska to the
110 mph isotach on the ANSI/ASCE 7-05 map. Further, HUD is updating the
U.S. territories to address only those regions applicable for U.S.
jurisdiction and proposes to eliminate reference to the Trust Territory
of the Pacific Islands. Lastly, HUD proposes that the entire territory
of Guam use a wind speed of 170 mph as shown in figure 6-1 of ANSI/ASCE
7-05. HUD has made correlating changes to the standards in this
proposed rule, where appropriate, to account for these changes.
The reference standards for the structural design requirements for
welded connections would also be updated in Sec. 3280.305 to more
current AISI standards. New language is also added in this paragraph
(k) of this section to define and clarify ``attic areas'' and allow
standard computer truss modeling methodologies to be utilized to design
trusses. The proposal also establishes qualifying factors for the
requirement of the 20 psf live loads for design of ceiling joists/
bottom chords. To correct the interpretation that the entire attic
space must be designed for storage and the live load of 20 psf
[[Page 43122]]
regardless of whether the space was accessible for or capable of
accommodating storage space, the new qualifiers include criteria for
attic access opening, joist slope, and minimum insulation depth that
will allow for potential optimization of truss design and eliminate
designs based on unnecessary or unrealistic loading conditions. These
changes will allow the industry to value engineer structural roof
members and help the industry to remain competitive in providing
affordable housing.
The proposed rule would amend Sec. 3280.307 to require the
exterior wall envelopes to include a water resistive barrier (WRB)
behind the exterior cladding of manufactured homes, as well as a means
of draining water that enters the assembly. As most higher-end
manufactured homes already include a WRB as a standard feature, this
change will likely affect an estimated 30 percent% of the current
production. The use of a WRB is a commonly found product used in most
single-family home construction and is required by many state and local
codes. The WRB increases home resiliency and durability and offers a
second layer of protection from bulk water damage over the exterior
cladding.
The MHCC also recommended an edit to the former Sec. 3280.309,
changing manufactured homes to dwelling units, but the Health Notice on
formaldehyde emissions was removed from the MHCSS during the last
rulemaking and HUD will not take action on that recommendation.
Finally, proposed updates will add a new subsection Sec. 3280.309
to provide standards for vinyl siding and polypropylene siding used in
manufactured homes. Most siding manufacturers have instructions that
reference the Vinyl Siding Institute Installation Instructions, which
in turn reference ASTM standards. For consistency of both material and
installation requirements, this proposed change will require that vinyl
siding used in manufactured home construction comply with ASTM
standards and must be certified or listed and labeled as conforming to
those requirements.
E. Testing
The proposed rule would update and amend testing standards for
windows, sliding glass doors, and skylights under Sec. 3280.403,
egress windows and devices under Sec. 3280.404, and swinging exterior
passage doors under Sec. 3280.405, for use in manufactured homes. The
proposed rule would update standards for AAMA 1701.2 from the 1995
version to the 2012 version; ANSI Z97.1 from the 2004 version to the
2009 version; and AAMA 1702.2 from the 1995 version to the 2012
version. The proposed rule also adds AAMA/WDMA/CSA 101/I.S.2/A440-17
North American Fenestration Standard (NAFS) as an alternative
compliance path in the sections of the MHCSS that govern windows,
sliding glass doors, and skylights; egress windows; and swinging
exterior passage doors. Windows used in manufactured homes are often
exposed to some of their most severe service prior to the home being
installed, as they may be subjected to extreme wind pressure and
vibration while the home is being transported to the installation site.
Testing standards ensure that windows can withstand such pressures
while still performing to air and water specifications. The proposed
rule also requires fenestration products to be certified by an ISO/IEC
17065 accredited body, to ensure the competence, consistent operation
and impartiality of product, process, and service certification bodies.
This proposed rule change aligns the code with more current industry
standards.
F. Thermal Protection
The proposed rule updates the reference standards for vapor
retarder testing methods to a more current version of ASTM E96/E96M in
Sec. Sec. 3280.504. In Sec. 3280.510, clarifications are made to make
clear that heat loss and comfort cooling certificates must be visible
to home occupants and be permanently affixed within each dwelling unit
to accommodate multi-dwelling unit manufactured homes and that homes
designated as suitable for central air conditioning must provide
certified capacity information, including correct air supply entrances
and air return locations.
G. Plumbing Systems
The proposed rule would add flexibility for the use of heat tape or
piping heating cable used on plumbing systems in manufactured homes
under Sec. 3280.603(b)(4)(ii) to increase the number of available
options of heat tapes and pipe heating cables for use by consumers and
manufacturers to prevent freezing of plumbing pipes. Heat tape or pipe
heating cables used for manufactured homes are not different from those
used in conventional site-built homes. This change will allow
manufacturers to use heat tape or pipe heating cable listed or
certified for its intended purpose. The proposed rule would also update
reference standards for materials listed under Sec. 3280.604 to
current industry standards.
HUD also proposes to update the code governing the requirement for
shower compartment installation under Sec. 3280.607(b)(3). The rule
change will allow roll-in-type and transfer-type shower compartments
(accessible bathing fixtures) with thresholds that comply with ICC ANSI
A117.1, Standard for Accessible and Usable Buildings and Facilities,
and will permit manufacturers to install bathing systems designed to
serve people with disabilities. The current code imposes limitations on
accessible shower compartment features by requiring minimum dam or
threshold height. Currently, consumers have to remodel the existing
standard shower compartment to integrate an accessible shower
compartment or manufacturers need to obtain an Alternative Construction
letter to install accessible shower compartments. The proposed rule
change will codify accessible shower compartments into the MHCSS,
eliminating the need for Alternative Construction letters for
accessible shower compartments and allowing consumers to directly buy
homes with accessible shower compartments. Under Sec. 3280.609,
language is amended to clarify hot water supply systems are required
for each dwelling unit equipped with a kitchen sink, bathtub, and/or
shower.
In Sec. 3280.611, amendments are proposed to increase the maximum
distance of a fixture trap to the vent, commonly referred to as the
``trap arm.'' It is imperative that a plumbing fixture be located close
enough to the vertical vent pipe to prevent a siphon from where
existing water is pulled out of the trap rendering it ineffective. This
maximum distance is determined by the diameter and the number of
fixtures draining through the drain pipe. The proposed rule change
increases the maximum distance of the fixture trap to the vent thus
aligning the distances in the MHCSS with those of the International
Plumbing Code. This rule change affords plumbing engineers more
flexibility in designing circuit vents for any specific floorplan.
Bathroom fixtures (showers, sinks, toilets) must be located within the
distances prescribed from the vent pipe; therefore, the increased
maximum distances allow the designers to locate the vent pipe in the
walls to accommodate a preferred fixture layout, whereas previously the
layout may have required modification due to shorter permissible
distances and floor plan constraints (e.g., location of available walls
for the vent pipe). Consistency with other industry guidance
(International Plumbing Code
[[Page 43123]]
and the American Society of Plumbing Engineers) reduces the likelihood
of delays in the design approval process arising from designers using
standard industry practice but which resulted in trap arms that
exceeded the lengths previously allowed by the table in Sec.
3280.611(c).
H. Heating, Cooling and Fuel Burning Systems
The proposed rule would update the reference standards included in
the definitions for Class 0 air ducts and connectors under Sec.
3280.702 to UL 181-2013, more current UL standards. Reference standards
would also be updated in Sec. 3280.703 and two new standards (ANSI
Z21.10.3 and ANSI Z21.75) are proposed to be added for gas-fired water
heaters with input ratings above 75,000 British thermal units (Btu) per
hour, circulating and instantaneous; and electrical heating appliances
(UL 499-2014).
In Sec. 3280.705, standards for gas piping systems are proposed to
update the reference standards to more current editions. Reference
standards include criteria for establishing the suitability of
concealed mechanical tube fittings for use with concealed gas piping,
pipe joints in piping systems, and LP-gas supply connectors. Reference
standards for oil piping systems and heat producing appliances would
also be updated under Sec. 3280.706 and Sec. 3280.707. In addition,
Sec. 3280.705(j) would be revised to require a gas supply connector
for each dwelling unit of a multi-dwelling unit manufactured home
designed for gas supply.
In Sec. 3280.709(a), this proposed rule would remove the language
requiring manufacturers to leave appliance manufacturer instructions
attached to appliances. Section 3280.711 currently states that
``Operating instructions must be provided with each appliance. The
operating and installation instructions for each appliance must be
provided with the homeowner's manual.'' The current language in Sec.
3280.709 causes confusion as to whether it is necessary to ship two
installation instructions with each home, one with the appliance and
one with the homeowners' manual. Because all appliance manuals must be
provided with the homeowner's manual, this proposed rule change
eliminates potential redundancy for duplicate and unnecessary appliance
manuals. Furthermore, proposed revisions to Sec. 3280.711 to allow for
operating instructions requirements to be met through the provision of
permanent Quick Response (QR) codes would further streamline
documentation requirements for manufacturers.
In Sec. 3280.709(g), the proposed rule would ease requirements to
allow consumers and manufacturers to install any fireplaces and wood
stoves listed or certified for their intended purpose, instead of
limiting options to only those specifically listed for manufactured
homes. Installed fireplaces and wood stoves used for manufactured homes
are not different than those used for homes regulated by others, so
this proposed change would allow for greater flexibility and available
options for both consumers and manufacturers.
HUD also proposes to delete the prescriptive table of minimum
coefficient of performance (COP) ratios for electric heat pumps with
supplemental resistance heat under Sec. 3280.714(a)(1)(iii). These
heat pumps are only required to meet the minimum federal heating season
performance factor (HSPF) requirement. Current typical minimum COP
values already exceed the prescriptive minimum COP values from 1989, so
this rule change eliminates obsolete minimum standards and aligns the
MHCSS with current federal minimum efficiency requirements.
In Sec. 3280.715, the proposed rule change permits supply air
ducts located within 3 feet of the furnace discharge to be made of less
fire-resistant material if those ducts are rated to withstand the
maximum discharge air temperature of the equipment. All supply ducts
must still be made of galvanized steel, tin-plated steel, or aluminum
listed as Class 0 (air ducts and air connectors having surface burning
characteristics of zero) or Class 1 (air ducts and air connectors
having a flame-spread index of not over 25 without evidence of
continued progressive combustion and a smoke-developed index of not
over 50) in accordance with UL 181-2013. Previously, Class 1 ducts had
to be located at least three (3) feet from the furnace bonnet or
plenum, and furnace supply plenums had to be constructed of metal that
extends a minimum of three (3) feet from the heat exchanger measured
along the centerline of airflow. Manufacturers of Class 1 ducts
commonly offer products specifically listed for use in manufactured
homes, so the potential savings of this rule change would be realized
immediately.
I. Electrical Systems
The proposed rule would amend the definition for feeder assembly
under Sec. 3280.802(a)(20) to refer to ``dwelling unit'' instead of
``manufactured home.'' This change would accommodate the integration of
multi-dwelling unit manufactured homes. Power supply requirements under
Sec. 3280.803(a) are clarified to not apply to multi-dwelling unit
manufactured homes, and National Electric Code references under
Sec. Sec. 3280.803(k)(3)(ii), 3280.804, and 3280.808(p) are updated to
reference applicable articles of the National Electrical Code, NFPA 70-
2014 for a more current standard. The code requirements for
disconnecting means, consisting of a circuit breaker, or switch and
fuses and accessories, would be streamlined under Sec. 3280.804 and
clarified to refer to dwelling units instead of manufactured homes.
MHCSS language for branch circuit requirements under Sec. 3280.805 and
wiring methods and materials under Sec. 3280.808 are also simplified
for improved clarity.
J. Revisions to Standards Incorporated by Reference (Reference
Standards)
The following table lists the standards incorporated by reference
(IBRed) that would be revised or added by this proposed rule. Each
reference standard is preceded with an indicator to identify the type
of change being made. Reference standards designated ``N'' are new,
meaning they have not been codified into the MHCSS. Reference standards
designated ``U'' are being updated, that is HUD is incorporating an
updated or more recent version of an already codified standard.
Reference standards designated ``*'' are not new or being updated but
have already been codified in the MHCSS and are being added to a
different section from that codified. The sections of the MHCSS that
would be amended by each modification are also shown on the right of
the reference standard being added or updated:

The Department is interested in receiving comments from the public
as to whether the use of any of the reference standards would result in
[[Page 43132]]
reduced safety or performance levels for manufactured home occupants.
K. Changes to the Manufactured Home Procedural and Enforcement
Regulations (24 CFR Part 3282)
HUD is proposing a single revision to its Manufactured Home
Procedural and Enforcement Regulations at 24 CFR part 3282.
Specifically, HUD is proposing to remove paragraph (l) from Sec.
3282.8. This change would remove ``multifamily homes'' from the
section's applicability provisions.
L. Changes to the Model Manufactured Home Installation Standards (24
CFR Part 3285)
HUD is proposing changes to the Model Manufactured Home
Installation Standards at 24 CFR part 3285 to revise definitions to
allow certain specified roof ridge designs without a requirement for
specific on-site inspections by the Production Inspection Primary
Inspection Agencies (IPIAs), in those instances where it is to better
support a type of roof installation that is now common throughout the
industry and is a time-tested technology. Other proposed changes
support broader criteria for fireplaces and woodstoves, as well as
proposed changes to the Construction and Safety Standards for fire
sprinkler certification and testing requirements, and modifications to
water supply testing provisions to accommodate more types of piping
materials. HUD proposes to add language under subpart F--Optional
Features, to ensure that residential fire sprinkler systems are
certified and tested on site in accordance with home manufacturer's
instructions and to ensure that a required listed minimum water supply
is available for any systems installed. Testing requirements are to be
consistent with Sec. 3280.612(a) and certified by the installer.
Proposed revisions to part 3285 also include revised language in
Sec. 3285.603(d)(3) to support the changes under Sec.
3280.603(b)(4)(ii) for heat tape or pipe heating cable use.
M. Changes to the Manufactured Home Installation Program (24 CFR Part
3286)
HUD is proposing changes to the Manufactured Home Installation
Program at 24 CFR part 3286 to clarify and ensure that manufacturer
instructions, alternative designs, and installation instructions are
provided to purchasers and homeowners. Changes would also ensure that
licensed installers must receive installation instructions in order to
properly install the homes. Proposed changes also include clarifying
the financial damage coverage prerequisites for installer applicants to
qualify for installation licenses. An irrevocable letter of credit was
added as an option in place of the surety bond to give installers
another financial avenue to meet the licensing requirements, while
still ensuring the same coverage to consumers. Changes will codify what
has been discovered by the HUD-administered Manufactured Home
Installation Program as necessary to provide adequate coverage to
consumers in the case of damage to or loss of a manufactured home
resulting from installation defects.
III. Incorporation by Reference
Before HUD issues a final rule, the consensus standards proposed
for incorporation will be approved by the Director of the Federal
Register for incorporation by reference in accordance with 5 U.S.C.
552(a) and 1 CFR part 51. For purposes of this proposed rule, HUD has
established an electronic reading room which provides links to access
the consensus standards that would be added or updated by this rule.
These standards will be available for review during the public comment
period for this rule. The reading room can be accessed at: www.hud.gov/program_offices/housing/rmra/mhs/readingroom.
Supplemental descriptions of the standards are provided in the
following list. In addition, copies of these standards may be obtained
from the organization that developed the standard. Finally, as
described in Sec. 3280.4, these standards are available for inspection
at HUD's Office of Manufactured Housing Programs. Due to security
measures at the HUD Headquarters building, however, an advance
appointment to review standards must be scheduled by calling the Office
of Manufactured Housing Programs 202-708-1112 (this is not a toll-free
number).
The following 88 consensus standards for Manufactured Housing are
proposed for approval for incorporation by reference:
1. ANSI/AHRI Standard 210/240-2008 with Addenda 1 and 2, Unitary
Air-Conditioning and Air-Source Heat Pump Equipment. The proposed rule
would update ANSI/ARI 210/240-89, Unitary Air-Conditioning and Air
Source Heat Pump Equipment. This standard establishes definitions,
classifications, test requirements, rating requirements, minimum data
requirements for published ratings, operating requirements, marking and
nameplate data, and conformance conditions for Unitary Air-Conditioners
and Air-Source Unitary Heat Pumps. This standard is available through
HUD's online reading room.
2. AAMA 1701.2-12, Voluntary Standard for Utilization in
Manufactured Housing for Primary Window and Sliding Glass Doors. The
proposed rule would update AAMA 1701.2-95. This standard sets the
requirements for primary windows and sliding glass doors used in
manufactured housing. Window mounted as components in entry doors are
beyond the scope of this standard. Since building methods and materials
are expected to undergo continued design innovation, the purpose of
this standard is to establish reasonable performance standards for all
present and future methods and materials of construction. This standard
is available through HUD's online reading room.
3. AAMA 1702.2-12, Voluntary Standard for Utilization in
Manufactured Housing for Swinging Exterior Passage Doors. The proposed
rule would update AAMA 1702.2-95, Voluntary Standard Swinging Exterior
Passage Door for Utilization in Manufactured Housing. This standard
sets the requirements for swinging exterior passage doors and
combination doors used in manufactured housing. Windows used in
swinging exterior passage doors are components of the door and are thus
included in this standard. Since building methods and materials are
expected to undergo continued design innovation, the purpose of this
standard is to establish reasonable performance standards for all
present and future methods and materials of construction. This standard
is available through HUD's online reading room.
4. AAMA 1704-12, Voluntary Standard Egress Window Systems for
Utilization in Manufactured Housing. The proposed rule would update
AAMA Standard 1704-1985. This standard sets the requirements for the
design, construction, and installation of egress window systems. This
standard is available through HUD's online reading room.
5. AAMA/WDMA/CSA 101/I.S.2/A440-17, North American Fenestration
Standard/Specification for Windows, Doors, and Skylights. The proposed
rule would update AAMA/WDMA/CSA 101/I.S.2/A440-08. The MHCC originally
recommended updating this standard to the 2011 version; however, more
recently the MHCC submitted another recommendation to update this
standard to the 2017 version. HUD proposes to update this standard to
the 2017 version as most recently approved by the MHCC, as this version
is already
[[Page 43133]]
referenced in HUD's industry-wide alternative construction approval for
doors. Incorporating the more recently recommended version will
eliminate the need for the industry-wide alternative construction
approvals for both doors and windows that address pandemic-related
supply chain shortages. This standard establishes material-neutral,
minimum, and optional performance requirements for windows, doors,
secondary storm products, tubular daylighting devices, roof windows,
and unit skylights. The specification concerns itself with the
determination of performance grade, design pressure, and related
performance ratings. This standard is available through HUD's online
reading room.
6. ANSI/AHA A135.4-2012, Basic Hardboard. The proposed rule would
update ANSI/AHA A135.4-1995. This standard covers requirements and test
methods for water resistance, thickness swelling, modulus of rupture,
tensile strength, surface finish, dimensions, squareness, edge
straightness, and moisture content of five classes of basic hardboard.
This standard requires test methods determined by the ASTM,
International where appropriate and provides methods of identifying
hardboard that is compliant. This standard is available through HUD's
online reading room.
7. ANSI/AHA A135.5-2012, Prefinished Hardboard Paneling. The
proposed rule would update ANSI/AHA A135.5-1995. This standard covers
requirements and methods of testing for the dimensions, squareness,
edge straightness, and moisture content of prefinished hardboard
paneling and for the finish of the paneling. Methods of identifying
products which conform to ANSI/AHA A135.5 are included. This standard
is available through HUD's online reading room.
8. ANSI/AHA A135.6-2012, Hardboard Siding. The proposed rule would
update ANSI/AHA A135.6-1998. This standard sets requirements and
methods of testing for the dimensions, straightness, squareness,
physical properties, and surface characteristics of engineered wood
siding at the time of manufacture. This standard is available through
HUD's online reading room.
9. AISC 360-10, Specifications for Structural Steel Buildings. The
proposed rule would update AISC-S335, 1989, Specification for
Structural Steel Buildings--Allowable Stress Design and Plastic Design
(except for the following parts of this standard which are specifically
excluded from use: 1.3.3, 1.3.4, 1.3.5, 1.3.6, 1.4.6, 1.5.1.5, 1.5.5,
1.6, 1.7, 1.8, 1.9, 1.10.4 through 1.10.7, 1.10.9, 1.11, 1.13, 1.14.5,
1.17.7 through 1.17.9, 1.19.1, 1.19.3, 1.20, 1.21, 1.23.7, 1.24, 1.25.1
through 1.25.5, 1.26.4, 2.3, 2.4, 2.8 through 2.10), June 1, 1989. This
specification provides the generally applicable requirements for the
design and construction of structural steel buildings and other
structures. This standard is available through HUD's online reading
room.
10. AISI S100-12, North American Specification for the Design of
Cold-Formed Steel Structural Members. The proposed rule would update

the installation of natural and propane gas piping systems using
corrugated stainless steel tubing in residential, commercial, or
industrial buildings. This includes requirements for the installation
of corrugated stainless steel piping systems in which portions of the
piping are exposed to the outdoors as required to make connections to
outdoor gas meters or to outdoor gas appliances, which are attached to,
mounted on, or located near the building structure. This standard is
available through HUD's online reading room.
13. ANSI Z21.1-2016, Household Cooking Gas Appliances. The proposed
rule would update ANSI Z21.1-2000. This standard specifies guidelines
for the newly produced household cooking gas appliances constructed
entirely of new, unused parts and materials. These appliances may be
floor-supported or built-in. This standard is available through HUD's
online reading room.
14. ANSI Z21.5.1-2015, Gas Clothes Dryers Volume 1, Type 1 Clothes
Dryers. The proposed rule would update ANSI Z21.51.1-1999, Gas Clothes
Dryers Volume 1, Type 1 Clothes Dryers, with Addendum z21.5.1a-1999.
This standard specifies guidelines for newly produced Type 1 clothes
dryers constructed entirely of new, unused parts and materials for use
with natural gas, manufactured gas, mixed gas, propane gas, LP gas-air
mixtures, and for mobile home installation. This standard is available
through HUD's online reading room.
15. ANSI Z21.10.1-2014, Gas Water Heaters Volume 1, Storage Water
Heaters with Input Ratings of 75,000 BTU per hour or Less. The proposed
rule would update ANSI Z21.10.1-1998, Gas Water Heaters--Volume 1,
Storage Water Heaters with Input Ratings of 75,000 BTU per hour or
Less, with Addendum Z21.10.1a-2000. This standard specifies guidelines
for newly produced, automatic storage water heaters having input
ratings of 75,000 Btu/hr (21,980 W) or less, hereinafter referred to as

and materials. This standard is available through HUD's online reading
room.
16. ANSI Z21.10.3-2014 Gas-fired Water Heaters Volume 3, Storage
Water Heaters with Input Ratings Above 75,000 BTU per Hour, Circulating
and Instantaneous. This proposed rule would add this standard for
incorporation by reference. This standard specifies guidelines for
newly produced, large automatic storage water heaters having input
ratings about 75,000 Btu/hr (21,980 W), instantaneous water heaters,
and circulating water heaters including booster water heaters,
constructed entirely of new, unused parts and materials. This standard
is available through HUD's online reading room.
17. ANSI Z21.15-2009, Manually Operated Gas Valves for Appliances,
Appliance Connector Valves and Hose End Valves. The proposed rule would
update ANSI Z21.15-1997. This standard applies to manually operated gas
valves not exceeding 4 inch (102 mm) pipe size, and pilot shut-off
devices. This standard is available through HUD's online reading room.
18. ANSI Z21.19-2014, Refrigerators Using Gas Fuel. The proposed
rule would update ANSI Z21.19-1990, with Addendum ANSI Z21 19a-1992 and
ANSI Z21 19b-1995. This standard specifies guidelines for gas-fired
refrigerators having refrigerated spaces for storage of foods, storage
of foods and making ice, storage of frozen foods and making ice, or
storage of foods and the storage of frozen foods and making ice. The
standard applies to newly produced refrigerators constructed entirely
of new, unused parts and materials. This
[[Page 43134]]
standard is available through HUD's online reading room.

available through HUD's online reading room.
21. ANSI Z21.23-2000 (R2005), Gas Appliance Thermostats with ANSI
Z21.23a-2003 (Addenda1) and ANSI 21.23b-2005 (Addenda 2). This proposed
rule would update ANSI Z21.23-1993. This standard specifies guidelines
for newly produced gas appliance thermostats of the integral gas valve
type having a maximum operating gas pressure of \1/2\ psi (3.5 kPa) or
electric type. This standard is available through HUD's online reading
room.
22. ANSI Z21.24-2006 (R2011), Connectors for Gas Appliances. This
proposed rule would update ANSI Z21.24-1997/CGA 6.10-M97, Connectors
for Gas Appliances, and remove the reference to the Compressed Gas
Association. This standard specifies guidelines for newly produced gas
appliance connectors constructed entirely of new unused parts and
materials, having nominal internal diameters of \1/4\, \3/8\, \1/2\,
\5/8\, \3/4\ and 1 inch, and having fittings at both ends provided with

frequently moved after installation. This standard is available through
HUD's online reading room.
23. ANSI Z21.40.1-1996, Gas Fired, Heat Activated Air Conditioning
and Heat Pump Appliances. This proposed rule would correct the title of
this standard from ANSI Z21.40.1-1996/CGA 2.91-M96, Gas-Fired, Heat
Activated Air Conditioning and Heat Pump Appliances, to remove the
reference to the Compressed Gas Association. This standard has already
been approved for incorporation by reference for Sec. Sec. 3280.703
and 3280.714(a) by the Director of the Office of the Federal Register
and is unchanged. This standard is available through HUD's online
reading room.
24. ANSI Z21.47-2012, Gas Fired Central Furnaces (Except Direct

parts and materials. This standard is available through HUD's online
reading room.
26. ANSI Z97.1-2009, Standard for Safety Glazing Materials used in
Buildings--Safety Performance Specifications and Methods of Test. The
proposed rule would update ANSI Z97.1-2004, Standard for Safety Glazing
Materials used in Buildings--Safety Performance Specifications and
Methods of Test, copyright 2004. This standard establishes the
specifications and methods of test for the safety properties of safety
glazing materials (glazing materials designed to promote safety and to
reduce or minimize the likelihood of cutting and piercing injuries when
the glazing materials are broken by human contact) as used for all
building and architectural purposes. The updated standard adds
modifications and new material that add clarity of purpose, intent and
procedures. Specifically, sections have been rewritten and new sections
added to provide additional assurance that the intended safe-break
characteristics have been achieved before a test specimen may be
declared compliant. This reference standard impacts the HUD Code to
define safety glazing materials used in glass and glazed openings such
as windows and sliding glass doors, and hazardous locations requiring
safety glazing. The scope of this standard is available through HUD's
online reading room.
27. APA D510C-2012, Panel Design Specification. The proposed rule
would replace APA D410A-2004, Panel Design Specification. This standard
specifies guidelines for newly produced assembled connectors
constructed entirely of new, unused parts and materials. This standard
is available through HUD's online reading room.

proposed rule would update APA H815E-1995 (PDS Supplement #5), Design
and Fabrication of All-Plywood Beams. This standard presents
recommended methods for the design and fabrication of staple-glued all-
plywood beams. Allowable stresses and other design criteria are
provided, as well as guidelines for beam fabrication. This standard is
available through HUD's online reading room.
30. APA PS 1-09, Structural Plywood (with Typical APA Trademarks).
This proposed rule would add this standard for incorporation by
reference. This standard specifies guidelines for producing, marketing,
and specifying plywood for construction and industrial uses. This
standard is available through HUD's online reading room.
31. APA S811P-2013, Design & Fabrication of Plywood Curved Panels.
The proposed rule would update APA S811M-1990 (PDS Supplement 1),
Design and Fabrication of Plywood Curved Panels. This specification
presents the recommended method for the design and fabrication of
curved plywood roof panels spanning between load-bearing supports so
that the stresses developed act circumferentially around the curve.
This standard is available through HUD's online reading room.
32. APA S812S-2013, Design & Fabrication of Glued Plywood Lumber
[[Page 43135]]
Beams. The proposed rule would update APA S812R-1992, Design and
Fabrication of Glued Plywood-Lumber Beams, revised November 1998,
Supplement #2, July 1992. This specification presents the recommended
method for the design and fabrication of glued plywood and lumber
beams. This standard is available through HUD's online reading room.

IV. Findings and Certifications
Regulatory Planning and Review
Under Executive Order 12866 (Regulatory Planning and Review), a
determination must be made whether a regulatory action is significant
and, therefore, subject to review by the Office of Management and
Budget (OMB) in accordance with the requirements of the order.
Executive Order 13563 (Improving Regulations and Regulatory Review)
directs executive agencies to analyze regulations that are ``outmoded,
ineffective, insufficient, or excessively burdensome, and to modify,
streamline, expand, or repeal them in accordance with what has been
learned.'' Executive Order 13563 also directs that, where relevant,
feasible, and consistent with regulatory objectives, and to the extent
permitted by law, agencies are to identify and consider regulatory
approaches that reduce burdens and maintain flexibility and freedom of
choice for the public.
The Office of Management and Budget (OMB) reviewed this rule under
Executive Order 12866 (entitled ``Regulatory Planning and Review'').
OMB determined that this rule is a ``significant regulatory action'' as
defined in section 3(f) of the Order (although not an economically
significant regulatory action, as provided under section 3(f)(1) of the
Order). Any changes made to the rule subsequent to its submission to
OMB are identified in the docket file, which is available for public
inspection at either www.regulations.gov or in the Regulations
Division, Office of the
[[Page 43140]]
General Counsel, Room 10276, 451 7th Street SW, Washington, DC 20410-
0500. HUD strongly encourages the public to view the docket file at
www.regulations.gov. Due to security measures at the HUD Headquarters
building, please schedule an appointment to review the docket file by
calling the Regulations Division at 202-402-3055 (this is not a toll-
free number). Individuals with speech or hearing impairments may access
this number via TTY by calling the Federal Relay Service at toll-free
800-877-8339.
Paperwork Reduction Act
The information collection requirements contained in this proposed
rule have been approved by the Office of Management and Budget (OMB)
under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). In
accordance with the Paperwork Reduction Act, an agency may not conduct
or sponsor, and a person is not required to respond to, a collection of
information unless the collection displays a valid control number. OMB
has issued HUD the control number 2502-0253 for the information
collection requirements under the current Manufactured Housing
Construction and Safety Standards Program.
Unfunded Mandates Reform Act
Title II of the Unfunded Mandates Reform Act of 1995 (2 U.S.C.
1531-1538) establishes requirements for Federal agencies to assess the
effects of their regulatory actions on State, local, and tribal
governments and the private sector. This rule will not impose any
Federal mandates on any State, local, or tribal government or the
private sector within the meaning of the Unfunded Mandates Reform Act
of 1995.
Environmental Review
A Finding of No Significant Impact with respect to the environment
has been made in accordance with HUD regulations at 24 CFR part 50,
which implement section 102(2)(C) of the National Environmental Policy
Act of 1969 (42 U.S.C. 4332(2)(C)). The Finding of No Significant
Impact is available for public inspection on www.regulations.gov and
between the hours of 8 a.m. and 5 p.m. weekdays in the Regulations
Division, Office of General Counsel, Room 10276, Department of Housing
and Urban Development, 451 Seventh Street SW, Washington, DC 20410-
0500.
Regulatory Flexibility Act
The Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.)
generally requires an agency to conduct a regulatory flexibility
analysis of any rule subject to notice and comment rulemaking
requirements, unless the agency certifies that the rule will not have a
significant economic impact on a substantial number of small entities.
The rule, as proposed, would regulate establishments primarily
engaged in making manufactured homes (NAICS 32991). The Small Business
Administration's size standards define an establishment primarily
engaged in making manufactured homes as small if it does not exceed
1,250 employees. HUD believes that many of the manufacturers included
under this NAICS definition fall below the small business threshold of
1250 employees. The proposed rule would apply to all of the
manufacturers. The rule would, thus, affect a substantial number of
small entities. HUD has determined, however, that this rule would not
have a significant economic impact on a substantial number of small
entities.
As discussed in the economic impact analysis prepared for this
proposed rule, however, most of the revisions proposed by this rule
would not affect costs of manufacturers, large or small, and provide
benefit to homeowners. Further, of the nine code changes proposed by
this rule that would affect the cost of design, production, or
installation of manufactured homes, seven would decrease the costs of
manufacturing or would provide manufacturers additional flexibility in
the design of the home. Only two proposed revisions would increase
costs and have an ambiguous impact on costs. The proposed revisions
that increase costs, however, would increase fire safety save lives,
reduce injury, and reduce property damage. This rule also proposes four
changes that would eliminate the need for manufacturers to prepare and
submit an Alternate Construction (AC) letter, providing all
manufacturers, large and small, additional cost savings and increased
flexibility in design. These provisions would provide additional
options and increased flexibility in, for example, the design of
accessible shower stalls, multi-unit homes and revised floor plans.
Overall, the regulatory impact analysis prepared for this proposed
rule concluded that the decreased costs of design, production and
installation of manufactured homes would be between $9.5 million to
$23.3 million, annually. This overall decrease in production cost for
the manufacturer associated with this proposed rule would reduce burden
and result in an overall positive economic impact on manufacturers and
consumers. The regulatory impact analysis also provides that the rule,
as proposed, would produce net benefits ranging from $18.8 million to
$21.8 million.
Notwithstanding HUD's determination that this rule, as proposed,
would not have a significant economic effect on a substantial number of
small entities, HUD specifically invites comments regarding this
certification and any less burdensome alternatives to this rule that
will meet HUD's objectives as described in this preamble.
Executive Order 13132, Federalism
Executive Order 13132 (entitled ``Federalism'') prohibits, to the
extent practicable and permitted by law, an agency from promulgating a
regulation that has federalism implications and either imposes
substantial direct compliance costs on state and local governments and
is not required by statute, or preempts state law, unless the relevant
requirements of section 6 of the Executive Order are met. This rule
does not have federalism implications and does not impose substantial
direct compliance costs on state and local governments or preempt state
law within the meaning of the Executive Order.

such as CPVC and PEX, shall be listed for use in residential fire
sprinkler systems. Nonmetallic pipe and tubing systems shall be
protected from exposure to the living space by a layer of not less than
5/16 inch thick gypsum wallboard, \1/2\ inch thick plywood, or other
material having a 15 minute fire rating. Pipe protection shall not be
required where exposed piping is permitted by the pipe listing and in
areas that do not require protection with sprinklers as specified in
paragraph (c) of this section.
(k) Shutoff valves. Shutoff valves shall not be installed in any
location where the valve would isolate piping serving one or more
sprinklers, except for shutoff valves installed for the entire water
distribution system.
(l) Means of drainage. A means to drain the sprinkler system shall
be provided on the system side of the water supply inlet.
(m) Minimum flow rate. The sprinkler system must provide at least
the flow rate required to produce a minimum discharge density of 0.05
gpm/ft\2\ from each sprinkler and be determined by using the sprinkler
manufacturer's published data for the specific sprinkler model based on
the area of coverage, ceiling configuration, temperature rating and any
other conditions specified by the sprinkler manufacturer.
(n) Design flow rate. The design flow rate for the sprinkler system
shall be based on the following:
(1) The design flow rate for a room having only one sprinkler shall
be the flow rate required for that sprinkler, as determined by
paragraph (m) of this section.
(2) The design flow rate for a room having two or more sprinklers
shall be determined by identifying the sprinkler in that room with the
highest required flow rate, based on paragraph (m) of this section, and
multiplying that flow rate by two.
(3) Where the sprinkler manufacturer's instructions specify
different criteria for ceiling configurations that are not smooth, flat
and horizontal, the required design flow rate for the room shall comply
with the sprinkler manufacturer's instructions.
(4) The design flow rate for the sprinkler system shall be the flow
required by the room with the largest flow rate, based on paragraph
(n)(1), (2), or (3) of this section.
(5) For the purposes of this section, it shall be permissible to
reduce the design flow rate for a room by subdividing the space into
two or more rooms, where each room is evaluated separately with respect
to the required design flow rate. Walls and a ceiling shall bound each
room. Openings in walls shall have a lintel (header) not less than 8
inches in depth and each lintel shall form a solid barrier between the
ceiling and the top of the opening.
(o) Pipe sizing and minimum required supply pressure. (1) The
piping to sprinklers shall be sized for the flow required by paragraph
(n) of this section. The flow rate required to supply the plumbing
fixtures shall not be required to be added to the sprinkler design flow
rate. The minimum pipe size from the water supply inlet to any
sprinkler shall be \3/4\ inch diameter. Threaded adapter fittings at
the point where sprinklers are attached to the piping shall be a
minimum of \1/2\ inch diameter.
(2) Piping shall be sized by determining the available pressure to
offset friction loss in piping and identifying a piping material,
diameter and length in accordance with the following:
(i) Minimum Supply Pressure Required. The following equation shall
be used to determine the required supply pressure at the fire sprinkler
system supply inlet.
Equation 1 to paragraph (o)(2)
PSUP = PT+PLE+PSP
Where:
PSUP = Pressure required at the fire sprinkler system supply inlet.
(Note: This is the pressure which is entered on the Fire Sprinkler
System Certificate under ``Minimum Water Supply Required.'')
PT = Pressure loss in the fire sprinkler system piping.
PLE = Pressure loss from elevation change. (Note: Normally 4.4 psi
for single story houses and 8.7 psi for two story houses).
PSP = Maximum pressure required by a sprinkler.
(ii) [Reserved]
(3) Determination of PSUP shall be in accordance with the following
procedure:
(i) Step 1. Determine PT. For the specific design in question
determine the distance (developed length) from the fire sprinkler
system supply inlet to the most remote sprinkler. Refer to Tables
8.4.10.2(a) through (i) of NFPA 13D (incorporated by reference, see
Sec. 3280.4) and select the correct table for the fire sprinkler
system pipe material and pipe size used. Using the system design flow
rate from paragraph (m) of this section find the ``Allowable length of
pipe'' column which is closest to, but not less than, the developed
length for the design in question. The ``Allowable Pressure'' in the
column heading is PT. (Note: Interpolation between ``Allowable length
of pipe'' (developed length) and ``Available Pressure'' (PT) is
permitted. Example: Using Table 8.4.10.2(d) of NFPA 13D, Sprinkler Flow
Rate = 16 gpm, developed length = 70 feet, Available Pressure (PT) =
17.5 psi)
(ii) Step 2. Determine PLE. Refer to Table 8.4.10.2.(c) of the NFPA
13D. The elevation used in applying the table shall be the difference
between the highest sprinkler and the fire sprinkler system supply
inlet. Interpolation is permitted. (Note: If the highest sprinkler is
lower than the fire sprinkler system supply inlet then subtract this
value in equation 1 to paragraph (o)(2) of this section, instead of
adding it.)
(iii) Step 3. Determine PSP. Determine the maximum pressure
required by any individual sprinkler based on the flow rate for each
sprinkler as set forth in paragraph (m) of this section. The required
pressure is provided in the data provided by the sprinkler manufacturer
for the specific model based on the selected flow rate.
(p) Testing. The fire sprinkler system piping shall be subject to
the same test as the water distribution system in Sec. 3280.612(a).
For multipurpose fire sprinkler systems, it shall be permitted to test
the fire sprinkler system piping simultaneously with the domestic water
distribution system.
[[Page 43150]]
(q) Fire Sprinkler System Certificate. The manufacturer must
permanently affix a Fire Sprinkler System Certificate adjacent to the
data plate. The manufacturer must specify on the Fire Sprinkler System
Certificate the minimum required pressure in pounds per square inch
