Texas Permit & Stamping Requirements
Requirements vary by region, code cycle, seismic zone, and wind or snow load. Here is what typically drives design for Texas projects.
What Drives Design in Texas
Texas projects are governed primarily by wind uplift and coastal exposure.
- ✓ Wind load design per ASCE 7 exposure category
- ✓ HVHZ or TDI windstorm documentation where applicable
- ✓ Site grading and stormwater drainage plans
Exact code edition and local amendments vary by city and county. We confirm the specific requirements for your address before drafting.
Code in effect in Texas
Texas has no single statewide building code. The International Residential Code is the minimum standard for residential construction in cities that enforce codes, and each city adopts its own edition and local amendments. Most major Texas cities are on the 2018 or 2021 International Codes.
What to plan for
- ✓ Texas Department of Insurance (TDI) windstorm certification applies in the 14 counties along the Gulf of Mexico.
- ✓ Texas Accessibility Standards (TAS) apply statewide to public buildings and require separate review.
- ✓ Many North Central Texas cities adopt the NCTCOG regional amendments to keep codes consistent across the region.
Code information last verified September 2026. Codes change, so we confirm the edition in force for your address before drafting.
Frequently asked questions about Texas permits
Does Texas have a statewide building code?
No. The state sets minimums, but each city adopts and amends its own edition of the codes, so requirements in Houston can differ from Dallas or Austin. We confirm your city's adopted edition before drafting.
Do I need TDI windstorm certification?
If your project is in one of the 14 Gulf-coast counties covered by the Texas Windstorm Insurance Association, windstorm-compliant design and inspection is typically required. We design to the applicable wind requirements from the start.
