What Is the Price Per Square Foot to Build a New Home?
Why the number everyone asks for is the number that misleads most, and what to compare instead.
Price per square foot varies widely, and it's the most commonly misused number in home building. It's a useful sanity check between two nearly identical homes on nearly identical lots. It's close to meaningless as a way to compare custom builders.
Why the number misleads
- Finishes swing it enormously. The same plan, built twice with different cabinetry, counters, flooring, trim and fixtures, can land far apart on a per-foot basis. Nothing structural changed.
- Custom layouts aren't uniform. Production homes repeat, so their averages mean something. Custom homes don't repeat, so an average across them describes nobody's house.
- Site work is usually excluded. Excavation, grading, driveway, utility runs, septic and well are frequently left out of a quoted per-foot figure, and they vary more by lot than almost anything else. See site preparation.
- Nobody agrees what counts as square footage. Finished basement, garage, covered porches and bonus rooms are counted differently by different builders. Change the denominator and you change the answer.
- Bigger homes cost less per foot. Kitchens, baths and mechanicals are the expensive rooms and they don't scale up with the house. Two thousand square feet almost always prices higher per foot than three thousand. See why.
What to compare instead
Total project cost, against a written specification. Ask each builder for a line-item scope: what level of cabinetry, what window package, what flooring allowance, what's included for site work, what's excluded entirely. Two quotes are only comparable when the specifications are.
How we handle it
We produce a detailed estimate during the design phase built from your actual plan and specification. You'll know what's in it and what isn't before construction begins. See what drives the cost and what's typically excluded.
