Frequently asked questions — Texas permits
Does Texas have a statewide building code?
No. Texas does not mandate a statewide residential building code. Cities and counties adopt codes independently. Most major cities use the IBC/IRC, but rural areas may have no code at all.
Can I build anything I want on rural Texas land?
In unincorporated areas with no county building regulations — essentially yes. However, utility connections, septic systems, and any improvements within city extraterritorial jurisdiction may have requirements.
How does the Texas owner-builder permit work?
Homeowners can act as their own general contractor and pull permits for their primary residence. Licensed subcontractors are still required for trade work in most cities.
Why are Texas permit times faster than other states?
Texas cities have invested heavily in online permitting and streamlined plan review. Many trade permits are approved same-day or next-day. Austin and Houston have made significant improvements since 2020.
