Department of Housing and Urban Development, States, Manufacturers, and other involved in developing installation standards and instructions for manufactured housing as stipulated by the Manufactured Housing Improvement Act of 2000. The Model Manufactured Home Installation Standards serves as the basis for developing the manufacturers’ installation instructions as required by 24 CFR Part 3285. The Model Manufactured Home Installation Standards include methods for performing specific operations or assembly of a manufactured home that will not take the home out of compliance with the Manufactured Home Construction and Safety Standards . The planning and permitting processes, as well as utility connection, access, and other requirements, are outside of HUD's authority and may be governed by LAHJs. These Model Installation Standards do not attempt to comprehensively address such requirements. However, HUD recommends that the manufacturer's installation instructions include the information and advisories in this Subpart J, in order to protect the manufactured home, as constructed in accordance with the MHCSS.
Engineering analysis methods based on the principles of mechanics and/or structural engineering may be used to substantiate the adequacy of the transportation system to withstand in-transit loading conditions. As transportation loadings are typically critical in the longitudinal direction, analysis should, in particular, provide emphasis on design of longitudinal structural components of the manufactured home (e.g., main chassis girder beams, sidewalls, and rim joists, etc.). Notwithstanding, all structural elements necessary to the structural integrity of the manufactured home during in-transit loading are also to be evaluated (e.g., transverse chassis members and floor framing members, etc.). Tests must be witnessed by an independent registered professional engineer or architect, manufacturer's IPIA or DAPIA, or by a recognized testing organization. Such testing procedures must be part of the manufacturer's approved design. Approved installation and the manufacturer's inspection procedures are provided for the connection of the site-installed heating appliance to the factory-installed circulation air system and return air systems.
§ 3280.212 Factory Constructed or Site-Built Attached Garages
Specific designs must be approved by a DAPIA and included in the home manufacturer installation instructions. On multi-section manufactured homes, install the sealer gasket on the ceiling, end walls, and floor mate-line prior to joining the sections together. Detailed drawings including all dimensions of the ground anchor assembly and its components. In line ground anchor assembly method. Ground anchor assembly installation and withdrawal procedures for test purposes must be as follows, and must be used consistently throughout all tests.
Piers used for perimeter support must be installed with the long dimension parallel to the perimeter rail. Horizontal offsets from the top to the bottom of the pier must not exceed one inch. Horizontal offsets from the top to the bottom of the pier must not exceed one-half inch.
Changes to the Model Manufactured Home Installation Standards (24 CFR Part
The changes included granting HUD the authority, for the first time, to establish model installation standards for manufactured homes that would become nationwide minimum standards. These installation standards do not have the same preemptive effect as the construction and safety standards; rather, they establish minimum requirements for manufacturers to address through home installation instructions. The MHIA also created the Manufactured Housing Consensus Committee , a federal advisory committee composed of 21 voting members representing manufactured housing producers, retailers, consumers and consumer organizations, and general interest and public officials with an interest in manufactured housing.
HUD revised paragraph in this section in accordance with the public comments by creating an exception to the requirement for doors to closets, pantries, and doors to toilet compartments in single-section homes. Multi-section homes with electrical wiring in more than one section require crossover connections to join all sections of the home. The crossover must be designed in accordance with part 3280, subpart I of this chapter, and completed in accordance with the directions provided in the installation instructions. Only pipe heating cable listed for manufactured home use is permitted to be used, and it must be installed in accordance with the cable manufacturer installation instructions.
Automobile Safety & Fuel Economy
These programs or agencies should not be excluded, especially when state standards are often more stringent. Another commenter recommended that, for paragraph , that the nationally recognized testing agency be accredited to ISO/IEC or 17020. Garages beneath habitable rooms must be separated from all habitable rooms by 5/8-inch, Type X gypsum board or equivalent. Where the separation is a floor ceiling assembly, the structure supporting the separation must also be protected by not less than 1/2-inch gypsum board or equivalent. The design approval and the manufacturer's installation instructions must also include provision for equivalent vertical or horizontal separation between the garage and the manufactured home as appropriate.
Ducts penetrating the walls or ceilings separating the manufactured home from the garage must be constructed of a minimum No. 26 gauge steel or other approved material and must have no openings into the garage. When a manufactured home is factory constructed with an attached garage or is constructed for the attachment of a site-built garage, provisions must be made to provide fire separation between the garage and the manufactured home. The minimum headroom in all parts of the stairway must not be less than 6 feet 8 inches, measured vertically from the sloped plane adjoining the tread nosing or from the floor surface of the landing or platform. All bathroom passage doors in single-section homes must have a minimum clear opening width of 23 inches, and bathroom passage doors in multi-section homes must have a minimum clear opening width of 27 inches. Each toilet compartment must be a minimum of 30 inches wide, except, when the toilet is located adjacent to the short dimension of the tub, the distance from the tub, to the center line of the toilet must not be less than 12 inches.
IV. Incorporation by Reference
While the commenter did not suggest that HUD delay updates to Subpart M, HUD should be aware that substantial changes will likely be approved by the MHCC at its next meeting. The commenter also looked forward to the prompt implementation of the MHCC's recommended revisions to Subpart M, which the commenter believed will streamline the administrative process. One commenter suggested HUD eliminate “hard pipe” in paragraph , as the industry uses a flex gas connector and not a quick-disconnect. Two commenters proposed changes to HUD's regulatory text.
The specifications, standards, and codes of the following organizations are incorporated by reference in 24 CFR part pursuant to 5 U.S.C. 552 and 1 CFR part 51 as though set forth in full. The incorporation by reference of these standards has been approved by the Director of the Federal Register. If a later edition is to be enforced, the Department will publish a notification of change in the Federal Register. These incorporated standards are available for purchase from the organization that developed the standard at the corresponding addresses noted below. These standards are also available for inspection at the National Archives and Records Administration .
The MHCC prepared and submitted to HUD its third group of recommendations to improve various aspects of the Construction and Safety Standards. HUD reviewed those recommendations and adopted some of them after making editorial revisions and some additions. This final rule further revises the Construction and Safety Standards based on HUD's review and incorporation of certain public comments. In 1976, HUD established the Manufactured Home Construction and Safety Standards , commonly known as the HUD code. These federal standards regulate all aspects of construction, including design and construction strength, durability, transportability, fire resistance, and energy efficiency.

The manufacturer must ensure that any anchoring system designs incorporating anchorage to resist combined shear wall and carport uplift loads are evaluated for adequacy to resist the combined loads, taking into consideration the limitations of the ground anchor test and certification. A site‐built, self‐supported garage is considered an add‐on, per 3282.8, that does not affect the ability of the manufactured home to comply with the Construction and Safety Standards. The design and construction of the garage is subject to state and or local authorities having jurisdiction.
The Code of Federal Regulations is the official legal print publication containing the codification of the general and permanent rules published in the Federal Register by the departments and agencies of the Federal Government. The Electronic Code of Federal Regulations is a continuously updated online version of the CFR. It is not an official legal edition of the CFR. The eCFR is displayed with paragraphs split and indented to follow the hierarchy of the document.
