How much does it cost to build a house?
Enter your house size, region, and finish quality for a real construction cost range, built from NAHB's own published 2024 cost category breakdown and commonly cited 2026 regional cost per square foot data. Not a contractor bid — a real planning estimate before you talk to a builder.
2026 regional cost per square foot (standard finish)
| Region | Low | High |
|---|---|---|
| Northeast | $155/sqft | $200/sqft |
| Midwest | $100/sqft | $150/sqft |
| South | $109/sqft | $160/sqft |
| West | $220/sqft | $280/sqft |
Sourced from several independent 2026 cost-to-build guides that each cite NAHB/U.S. Census Bureau regional figures; exact numbers vary by source, so a range is shown rather than one invented number.

From an estimate to a real floor plan
- Size a budget first: see a real cost range before committing to a square footage or room count.
- Generate the actual layout: HomePlan's generator turns a plain description (bedrooms, bathrooms, square footage) into a real computed room layout in seconds — the same real room areas this cost estimate is built from once you have a plan.
- Check it against your lot: the Zoning Assistant tab checks real setbacks and lot coverage, with real live parcel data for Turkey, New York City, Chicago, Philadelphia, Seattle, Boston, and San Francisco.
Frequently asked questions
How much does it cost to build a 2,000 sqft house in 2026?
At the national midpoint regional range used here (roughly $125 to $240 per square foot depending on region and finish level), a 2,000 sqft house runs approximately $250,000 to $480,000 in construction cost alone, before land, financing, or builder profit. Use the calculator above with your own region and finish level for a tighter range.
Does this include the cost of land?
No. This is a construction cost estimate only — the cost to actually build the structure. Land, site surveys, well/septic (if not on municipal utilities), and financing costs are real additional costs this calculator does not estimate.
What's the difference between builder grade, standard, and premium finishes?
Builder grade uses entry-level laminate counters, stock cabinets, and carpet or vinyl flooring. Standard (the regional ranges below, as published) uses solid-surface counters, stock cabinets, and engineered wood or tile. Premium uses stone counters, custom cabinetry, hardwood or large-format tile, and upgraded windows and mechanical systems.
Why does region change the price so much?
Labor rates and material costs vary significantly by region. The West (particularly California and the Pacific Northwest) runs roughly $220 to $280 per square foot for standard finishes in the ranges used here, while the Midwest runs roughly $100 to $150 — more than double between the cheapest and most expensive region for the identical house.
Is a detached garage cheaper than an attached one?
This calculator only models an attached garage shell (roughly $30 to $55 per square foot for slab, framing, roofing, siding, and one garage door) since an attached garage shares a wall, roofline, and utilities with the house. A fully detached garage commonly costs more per square foot because it needs its own complete foundation, roof, and utility runs.
What's included in the NAHB cost breakdown?
NAHB's own 2024 Cost of Constructing a Home survey splits construction cost into: interior finishes (24.1%), major systems rough-in — plumbing, electrical, HVAC (19.2%), framing (16.6%), exterior finishes (13.4%), foundation (10.5%), site work including permits and utility hookups (7.6%), final steps like landscaping (6.5%), and other (2.1%). This calculator applies those real published shares to your estimated hard cost.
Should I add a contingency on top of this estimate?
Yes — this calculator already adds a commonly recommended 10% contingency on top of the hard cost, to cover real-world overruns like site-specific soil conditions, material price swings, and change orders that a square-footage estimate cannot see.
How accurate is a square-footage cost estimate?
It's a real planning estimate, not a bid. A square-footage calculator cannot see your specific lot's slope, soil conditions, local permit fees, or the exact quotes from your local contractors — all of which move a real number by tens of thousands of dollars. Use this to size a realistic budget before you talk to a builder, not as a final number.
