More technologically advanced than ever before, manufactured homes are homes built entirely in a factory under a federal building code administered by the U.S. Department of Housing and Urban Development (HUD).
The Federal Manufactured Home Construction and Safety Standards (commonly known as the HUD Code) went into effect June 15, 1976. Manufactured homes may be single- or multi-section and are transported to the site and installed. The federal standards regulate manufactured housing design and construction, strength and durability, transportability, fire resistance, energy efficiency and quality.
The HUD Code also sets performance standards for the heating, plumbing, air conditioning, thermal and electrical systems. It is the only federally-regulated national building code.
On-site additions, such as garages, decks and porches, often add to the curb-appeal of manufactured homes and must be built to local, state or regional building codes. (Courtesy of the Manufactured Housing Institute)
