A mobile home is a structure built prior to June 15, 1976. For information regarding Mobile Home Rehabilitation, please see the MOBILE HOME REHAB FAQ. A manufactured home is a structure constructed after June 15, 1976, built according to the Federal Manufactured Housing and Safety Standards Act (HUD Code). A manufactured home is for residential use only. Manufactured Homes (HUD) are regulated under the preemptive construction standards established by states and local governments. For an expanded definition of a manufactured home (i.e., length, size, chassis or foundation and utility requirements), see I.C. §39-4105. A modular building is any building, other than a manufactured or mobile home, that is of closed construction and is either entirely or substantially prefabricated or assembled at a place other than the building site. Modular buildings are built for residential or commercial use and the construction is regulated by the codes adopted by the state.
