Metal Building Permits in Texas: What to Know
Do you need a permit?
Usually yes — but it depends on where you are. Inside a city limit or ETJ, expect a permit and plan review. In unincorporated county land, rules are lighter and some ag structures are exempt, but many counties still require permits for occupied or large buildings.
Who issues it
Permitting runs through your city building department or the county. Every one of our county pages links to the verified local permit office and phone number so you can confirm current rules.
Engineered, stamped drawings
Most departments want the supplier's engineered, sealed drawings that show the building meets the local wind (and where applicable, snow and seismic) loads before they issue. A reputable supplier provides these.
The coast is stricter
In TDI catastrophe-area counties, windstorm certification (WPI-8) is layered on top of the normal permit. See our windstorm certification guide.
