Both manufactured homes and modular homes are rigorously inspected throughout the construction process in the factory, and receive either a State or Federal seal of approval before leaving the factory.

Manufactured homes are built to the federal building code, often referred to as the “HUD Code,” a performance-based building code. The federal building code allows for greater flexibility in integrating the latest in construction technologies, while still meeting the requirements of the code. The federal building code requires a home be built on a steel chassis that is an integral part of the home. In Minnesota, the Manufactured Home Building Code is part of the Minnesota State Building Code, which is enforced by the Minnesota Department of Labor and Industry, and by local building officials.

Modular homes are constructed to the International Industrial Residential Code, (IIRC), which is also a part of the Minnesota State Building Code. Modular homes are built on a removable steel frame that does not stay permanently a part of the home, and is returned to the factory after the home is affixed to the foundation.

Manufactured homes are predominantly single-story and are delivered to the home site in one, two or three sections. Flooring, cabinetry, fixtures, appliance, and plumbing have been installed at the factory. In the home has multiple sections, the sections are joined at the site, with minimal finishing work completed by a licensed installer when the home is affixed to its foundation. Manufactured home furnaces and water heaters are required to be located on the home’s main level.
