This final rule would modify the current exemption for recreational vehicles in the Manufactured Home Procedural and Enforcement Regulations.  Under the current exemption, questions have arisen regarding whether park model recreational vehicles are regulated by HUD's manufactured home program. These park models are being produced with patio roofs, screened in porches, and other extensions that exceed the 400 square foot maximum exemption in the current regulations. Additionally, some of these models are being marketed as suitable for year round living. Specifically, HUD’s final rule would provide an exemption for a recreational vehicle that meets HUD's definition of a manufactured home for a factory built vehicular structure that is not certified as a manufactured home, designed only for recreational use and not as a primary residence or for permanent occupancy, and built and certified in accordance with either the National Fire Protection Association (NFPA) 1192-2015, Standard for Recreational Vehicles, or the American National Standards Institute (ANSI) A119.5-15, Recreational Park Trailer Standard. In addition, to provide consumers notice regarding the manufacturing standards used to construct the unit, HUD’s rule would require that units claiming the exemption display a notice that identifies the standards used to construct the unit and states that the unit is designed only for recreational use, and not as a primary residence or permanent dwelling.
