Texas Construction Cost per Square Foot Calculator (2026)
Get a realistic budget range for building in Houston, Dallas, Austin or San Antonio. Pick your city, project type, finish level and size — the estimate updates instantly using typical 2025–2026 local costs.
Your project
Estimated total project cost
$407,000 – $621,000
$185–$270 / sq ft
These figures are typical 2025–2026 market ranges for planning only — not a quote. Actual cost depends on your scope, finishes, site conditions, code requirements (expansive-clay foundation engineering, Gulf Coast windstorm framing, 8.25% sales tax on materials) and current material prices. Keep a 10–20% contingency and confirm with a detailed line-item estimate.
Why a national average gets Texas wrong
National cost databases smooth out exactly the things that decide your Texas budget. That is why the same house costs very different amounts in Austin versus San Antonio.
Labor varies by metro
Austin carries some of the highest trade wages in the state on the back of relentless growth; San Antonio tends to be the most affordable major metro. A statewide number misses both.
Soil and code drive cost
Expansive clay soils force engineered post-tension or pier-and-beam foundations, and Gulf Coast counties add windstorm framing and inspection requirements — line items you will not find in a national average.
Finish level swings the range
Economy production and premium custom can differ 2–3x per square foot in the same city. Your finish choices matter as much as location.
From a rough range to a real estimate
This calculator is a starting point. OneEstimate turns it into a defensible, line-item estimate: our AI reads your plans and specs, builds the takeoff and cost breakdown, and lets you tune every rate to the actual Texas market instead of a national average.
- AI-generated line-item cost breakdowns from your plans
- Local labor and material rates you can adjust by market
- Add code-driven items (engineered foundations, windstorm framing) as their own lines
- Export clean proposals your clients understand
Frequently asked questions
How accurate is this Texas cost calculator?
It gives a realistic planning range using typical 2025–2026 cost-per-square-foot bands for each Texas metro, adjusted for project type and finish level. It is a starting point for budgeting — not a bid. A real estimate has to price your actual scope, site conditions and local code items (engineered foundations for expansive clay, Gulf Coast windstorm framing, permit fees).
What is included in the estimate?
The range covers hard construction cost (labor + materials) plus an allowance for soft costs (design, engineering, permits and fees) of roughly 10–15%. It excludes land, financing and furniture. Remember Texas charges 8.25% sales tax on materials in most metros, and always keep a 10–20% contingency on top for material volatility.
Why does cost per square foot vary so much across Texas?
Labor demand, soil and code drive most of it. Austin carries some of the highest trade wages in the state on the back of rapid growth, while San Antonio tends to be the most affordable major metro. Expansive clay foundations and Gulf Coast windstorm requirements then add cost in specific markets, and finish level and project type move your number up or down from the base band.
