What is the difference between a HUD-code manufactured home and a modular home?

NationwideReviewed October 2026

The main difference is which code the home is built to. A manufactured home is built in a factory to the federal HUD Code (24 CFR 3280), rides on a permanent chassis, and carries a red HUD certification label. A modular home is also factory-built, but in Texas it is built to the same codes as site-built housing, is installed on a permanent foundation, and becomes real property rather than receiving a title. In Texas, modular homes fall under TDLR's Industrialized Housing and Buildings program and carry a state decal or insignia. Both types still need local site approvals such as zoning, foundation, and utility connections, so check with your city or county before buying either.

Check your local rule. This varies by state, county or city. Your permitting office has the final word; the official lookup pages below show you who that is.
