This article is about the National Manufactured Housing Construction and Safety Standards Act of 1974 (42 U.S.C.A. §§ 5401-5426); 24 CFR Part 3280 and Part 3282.


The National Manufactured Housing Construction and Safety Standards Act of 1974 was enacted by Congress with the express purpose of directing the U.S. Department of Housing & Urban Development (HUD) to develop a preemptive code to regulate the construction of manufactured housing. (The term "mobile home" describes factory-built homes produced prior to the 1976 HUD Code enactment). Within the industry, this code is often referred to simply as "the HUD Code."

Please note that modular housing is not regulated under the National Manufactured Housing Construction and Safety Standards Act of 1974 and modular housing is not regulated by HUD. This is a common misconception as modular homes are regulated by individual states and must be built to each state's building code, just as a site built home is.

Passage of the 1974 act resulted in the promulgation of the Federal Manufactured Housing Construction and Safety Standards (FMHCSS). The original intent of the federal preemptive code was to provide consumers with a safe, low-cost alternative to conventional housing. At the same time, by preempting state and local jurisdictions from enacting additional requirements, producers could take advantage of the benefits of assembly line construction.
