Statewide offices
Building permits
Texas has no statewide residential building permit. If you are inside a city, the city issues permits; in unincorporated areas most counties have no building permit program, so check with your county first and with your septic and floodplain offices. Coastal properties also need windstorm certification to get state-backed windstorm insurance.
Check a builder's license
Texas does not license general home builders at the state level. Electricians, plumbers, and HVAC contractors are licensed by the state, so you can verify those trades. For builders, check references, written contracts, and complaints.
Energy code
The State Energy Conservation Office (Texas Comptroller) maintains the statewide residential energy code; your city or county building office enforces it where it has a program.
How Texas building rules work: the four situations
City code applies
Every Texas city uses the International Residential Code, with local amendments. Expect a permit and inspections.
Building inside city limits Rural, county opted inThree inspections
Foundation, framing, and completion, by a licensed engineer, architect or inspector. No county fee, no prior approval.
What each inspection checks Rural, no opt-inNo building permit
Septic, windstorm and deed rules still apply.
What still applies Near a cityCheck the ETJ
A city's rules can reach into its extraterritorial jurisdiction.
How to check your parcelSources: Texas Local Government Code §214.212 and §§233.151–233.154. Checked 7 Nov 2026. Texas permit guide
Septic and wells: who to contact
You'll almost certainly need a septic permit. A licensed site evaluator tests the soil first, and a licensed installer builds the system. Homes alone on 10 acres or more may be exempt under strict conditions. Texas septic guide
Septic permits
Your county (or another local authorized agent) issues septic permits in most of Texas; where there is no local agent, the state environmental agency (TCEQ) issues them. Look up your county to find who handles your permit.
Licensed septic installers & designers
The Texas Commission on Environmental Quality licenses septic installers and site evaluators, and engineers or registered sanitarians can also do the site evaluation and design.
Water wells
Private water well drillers and pump installers are licensed by the Texas Department of Licensing and Regulation. Many areas also have a local groundwater conservation district that may require a well permit.

View builderWhat a barndominium costs in Texas
Cost depends mostly on how finished you want it. These are the ranges Texas builders and kit sellers publish on their own websites. Ask any quote what it includes.
| What you buy | Per sq ft | 2,000 sq ft home |
|---|---|---|
| Kit only steel or post-frame materials; no slab, no labor | $19–$38 | $38k–$76k |
| Shell / dried-in erected and weather-tight; you finish inside | $25–$55 | $50k–$110k |
| Turnkey move-in ready; most quotes | $130–$250 | $260k–$500k |
Based on 8 kits from 3 sellers and published prices from 5 Texas builders, checked 7 Nov 2026. Basic turnkey finishes start near $100/sq ft; luxury runs $300+. Builders count square feet differently (living area vs. everything under roof), so compare like with like. See every source
