Foundations and the Difference Between Modular Homes, Manufactured Homes, Or Mobile Homes

It can be confusing to tell the difference between a manufactured home, mobile home, and/or modular home.

What are Manufactured Homes?

A manufactured home is any factory-built home in the United States that is built conforming to HUD Title 6 construction standards (commonly known as "the HUD-code"). The HUD-code was implemented and took effect starting June 15, 1976. A HUD-coded home will display documentation called the HUD Certification Label and the Data Plate. A manufactured home is also built on a permanent chassis to ensure transportability. However, typically a manufactured home is not moved from its initial installed site. The home can then be placed on HUD permanent foundation. This is what an professional engineer (like us at Foundation Certifications) inspects and certifies when we visit your home-site.

What are Mobile Homes?

A mobile home is similar to a manufactured home, in that it is a factory-built home. However, it differs in that it is: 1) built before June 15, 1976, and 2) not built to any uniform construction code, including HUD, since the HUD code didn't come out until June 15, 1976.

What are Modular Homes?

A modular home is any factory-built home that is constructed to a local (City or County), or state building code. Modular homes will not have the red HUD Certification Label, but will have a different label (often called a "UBC Label", or similar) attached to the home stating the code it complies with. A modular home can be built as an "on-frame" or "off-frame" modular. On-frame will be built on a permanent chassis, whereas, the off-frame modular will be built with removal of the chassis frame in mind.
