Federal act passed in 1974 regulating mobile homes. The act defines a mobile home as a "Structure, transportable in one or more sections, which is eight body feet or more in width and is forty body feet or more in length, and which is built on a permanent chassis, and designed to be used as a dwelling with or without permanent foundation, when connected to the required utilities, and includes the plumbing, heating, air-conditioning, and electrical systems contained therein". Mobile homes are well-equipped portable forms of housing including all necessities often including many luxurious appointments. mobile homes are distinguished from vans, campers and other recreational vehicles in that they are designed for permanent residence rather than recreational occupancy. Municipal zoning law often regulates the placement of mobile homes relegating them to mobile home park sites.
