NFPA 501: Standard on Manufactured Housing covers all the equipment and installations used in the design, construction, transportation, fire safety, plumbing, heat-producing, and electrical systems of manufactured homes.
The Standard covers virtually every aspect of safety. To be more comprehensive, the previous edition added requirements on safe rooms to provide a safe area for occupants of manufactured housing in areas prone to hurricanes, tornados, and other natural disasters. Requirements on water mist sprinkler systems reference the 2016 edition of NFPA 13D: Installation of Sprinkler Systems in One- and Two-Family Dwellings and Manufactured Homes.
Update to the 2017 edition for the latest safeguards.
Manufacturers, installers, and AHJs can depend on the 2017 edition of NFPA 501 for up-to-date requirements that help ensure the continued safety of manufactured housing.
