Manufactured homes are built under a national code administered by HUD and are often referred to as "HUD-Code homes" to distinguish them from other types of factory-built housing, such as modular. Installers, retailers, and inspectors of HUD-Code homes will be interested in the Manufactured Home Installation Training Manual, released from HUD's Office of Policy Development and Research.
HUD has designed the manual to complement manufacturer installation instructions, state regulatory documents, and installer training programs. A checklist at the end of the manual summarizes the main points of site preparation, foundations, installation, and additional resources.
