Who inspects a Texas modular (industrialized) home on site, inside or outside city limits?

TexasReviewed October 2026

It depends on where the home is installed. TDLR says that inside a city with a building department, local officials handle on-site inspections and can enforce zoning, setbacks and land-use rules. Outside city limits, on-site inspections are done by a TDLR-approved third-party inspector or a licensed architect or engineer. TDLR also says a permanent foundation is required, and a site plan showing utility locations plus approved foundation drawings must be provided before installation. A city cannot demand its own amendments to the state's mandatory codes as a condition of a permit or certificate of occupancy for a decaled industrialized building. Confirm the process with TDLR and your local office before delivery.

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.
