Mobile homes must be manufactured according to a code set by the U.S. Department of Housing and Urban Development. For example, manufacturers are required to build the homes on permanent chassis, HUD states.
Mobile homes built before the enforcement of the Manufactured Home Construction and Safety Standards on June 15, 1976, do not meet code, HUD states. HUD will not issue tags for those homes, and the Federal Housing Authority will not issue mortgages for them. HUD does not regulate mobile home parks but notes that there are associations in most states that can help those having trouble with a park.
The FHA has developed minimum requirements for mobile home parks, which provides a basis for the local regulation of the parks, according to the American Planning Association. The U.S. Department of Health, Education and Welfare has set standards for mobile home parks that cover such areas as water supply, sewage, pest control, electricity, lighting and fire protection. At the local level, the parks are governed by regulations regarding zoning and other concerns. As for state regulation, the APA has held up the California and New York housing divisions as exemplars in the regulation of areas such as plumbing and heating.
