Rugged Base Performance Requirements MHUS 2014 All Manufactured Homes

General The Federal Emergency Management Agency (FEMA) provides Manufactured Housing Units (MHUs), that meet the Housing and Urban Development standards as set forth in 24 CFR 3280 (Manufactured Home Construction Safety Standards “HUD Code”).The Robert T. Stafford Disaster Relief and Emergency Assistance Act, as amended and related authorities, as of April 2013, authorizes FEMA to provide temporary housing units, acquired by purchase or lease, directly to individuals or households who, because of available housing would be unable to make use of financial assistance. The Stafford Act also describes the decision criteria for determining which types of assistance will be provided; Stafford Act, Section (408)(b)(2)(B). Considerations include of cost effectiveness, convenience to the individuals and households, and such other factors as the President may consider appropriate. Consistent with these authorities, in the event that disaster survivors are unable to find suitable housing using financial assistance then FEMA Individual Assistance requires housing units available through purchase or lease.

The Agency intends to reuse these manufactured homes to house disaster survivors in several disaster events. These units will be subjected to extended road travel (in excess of 6,000 miles over their lifetime), multiple installations and un-installations, and a wide variety of weather conditions. The manufactured homes shall meet all of the requirements including having a complete Heating, Ventilation and Air Conditioning (HVAC) system and being furnished as described.

Legal Requirements The manufactured homes (as defined in 24 CFR 3280) being procured using these Performance Requirements shall meet and comply with all appropriate HUD requirements, regulations, standards, and guidance. The Rugged Based Performance Requirements does not constitute any expressed or implied deviation from or waiver of any requirements of the U.S. Department of Housing and Urban Development (HUD) Standards, Regulations, or its amendments or interpretative bulletins thereof. These units shall comply with HUD Standards, Regulations, and other appropriate HUD guidance and require a HUD Certification label to be placed as required in 24 CFR 3280.11 and a HUD Data Plate to be placed inside the unit as required in 24 CFR 3280.5. All units shall comply and meet the HUD approval process. These requirements do not provide the manufacturer with a waiver of the approval process for receiving an “Alternative Construction Letter (ACL).”FEMA anticipates that the manufacturer will have to apply for one or more ACL to meet the requirements of these FEMA Rugged Based Performance Requirements.

Additionally, FEMA procures MHUs to support disaster survivors with access and functional needs. Manufactured Housing built to meet this requirement is built in accordance to Architectural Barriers Act, 42 U.S.C. 4151-4157. The current construction requirements for the ABA are the Uniform Federal Accessibility Standards (UFAS 1984.)

A downloadable copy of UFAS can be found at http://www.access-board.gov/ufas/ufas.pdf and a searchable copy can be found at http://www.access-board.gov/ufas/ufas-html/ufas.htm. Technical assistance on UFAS is available from the U.S. Access Board by phone at 800-872-2253 or by email at TA@access-board.gov.
