Manufactured homes are subject to the Manufactured Home Construction and Safety Standards or “HUD Code” rather than local building codes, and display a red certification label on the exterior of each transportable section. The HUD code is a set of manufactured home industry standards published and maintained by HUD that establishes 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.
