Manufactured Home HUD Code Requirements
The "HUD code" is a set of manufactured home industry standards. Published and maintained by the U.S. Department of Housing and Urban Development (HUD), the code establishes the required standards for design and construction, strength and durability, fire resistance, energy efficiency, transportability, and quality control. It also sets performance standards for the heating and air conditioning, plumbing, thermal, and electrical systems.
Manufactured home insulation levels depend on the home's location within the United States. Since HUD standards are performance-based, HUD only specifies minimum home insulation levels for the entire house. The manufacturer of the home determines how much and where insulation will be installed in the home as long as it meets the HUD overall U-value—the inverse of thermal resistance (1/R)—for the climate zone where the home will be installed.
You can view the current HUD code information on the Part 3280: Manufactured Home Construction and Safety Standards Web page of the Title 24 Housing and Urban Development document. Section 3280.506 provides a chart of U-values and applicable zones throughout the United States. Section 3280.103 provides whole house ventilation requirements.
