Costs
There is no single U.S. price that can quote your lot. There are national benchmarks that show where money tends to go, and there is a better way to turn those benchmarks into a local decision: start with the national context, then ask three local builders to price the same written brief, with site work, allowances and exclusions kept visible as separate lines. That is the comparison this page is built to help you make.

Two public datasets are worth knowing before you read a quote. Neither of them is a price for your house. Both of them are useful for reading one.
The National Association of Home Builders surveys its builder members on what a single-family home cost them to build. In the 2024 survey, published January 2025, construction costs accounted for 64.4% of the average sales price in the sample and the finished lot for 13.7%. Construction cost itself broke down across eight stages:
| Stage of construction | Share of construction cost | What sits in it |
|---|---|---|
| Interior finishes | 24.1% | Drywall, trim, cabinets, flooring, paint, fixtures — the allowance lines. |
| Major system rough-ins | 19.2% | Plumbing, electrical, HVAC before anything is closed up. |
| Framing | 16.6% | Where the outline of the house is paid for. |
| Exterior finishes | 13.4% | Roof, siding, windows, doors — most of what the style pages are about. |
| Foundations | 10.5% | Moves with soil, slope and what the engineer requires. |
| Site work | 7.6% | Permits, engineering, utility connections, excavation. |
| Final steps | 6.5% | Landscaping, driveway, clean-up, the last punch list. |
| Other | 2.1% | Everything the survey could not place in the seven above. |
The Census Bureau's characteristics data for 2025 gives you the shape of the market rather than a price for your house: 1,005,000 single-family homes were completed, the median completed home was 2,142 square feet, and among new single-family homes sold the median price was $417,400 and the average $523,800.
Those sale prices include the land and the builder's margin, and they are dominated by production builders in the regions that build most. A custom house on a lot you already own is a different transaction, so the figure to take from this is the median size — because a quote for 2,142 square feet is the one you can compare with somebody else's quote. Not confirmed: we have not found a published national figure for what a custom home costs per square foot that would survive contact with your county, so this page does not print one.
The survey above is a national average. These are the seven places a local quote actually varies, and what to ask about each one.
Two lots at the same price are not the same cost. A sloped lot, poor soil, or a long run to the road can add a very large number before any house exists.
Clearing, leveling, drainage, driveway, water, power, sewer or septic. This is invisible in every photograph and every illustration, including ours.
A simple rectangle is the least complicated thing to build. Every corner, every change in roof direction and every level change adds work in several trades at once — framing, roofing, insulation, labor — which is why outline complexity usually shows up in a quote before finish selections do.
More peaks and more changes of direction mean more framing, more flashing and more labor. Whether metal or shingles costs more depends on the product, the gauge or weight and your region, so ask for both priced on the same roof rather than assuming. The published warranty documents differ more than the marketing does — we quote two of them in full on the modern farmhouse page.
Big glass and dark frames are usually upgrades. The cost scales with how many you specify, not just how big they are.
Cost per square foot here is several times that of the rest of the house. Adding one more bathroom is not a small decision.
The same drawing costs very different amounts in different states, and in different years. Both labor and materials move; which one is moving fastest changes year to year, so ask each builder what has changed in their pricing over the last twelve months and who carries the risk if it changes again before you break ground.
Why there is still no price per square foot on this page. The national figures above are real, and they are the wrong tool for your quote: they average across regions, lot conditions and builder types, and they are a year old before they are published. Numbers copied between websites go stale and nobody updates them. Use the national shares to check that a quote covers every stage, then ask three builders in your area for a range on a house the size you want and compare what each one includes. That comparison is the number that means anything.
Three quotes are only comparable if they are quoting the same house and showing the same lines. Print this, or write it into the brief the design tool gives you.
| Line | What to ask for | Why it moves the total |
|---|---|---|
| 1. Site work | Clearing, excavation, drainage, driveway, and each utility connection priced individually. | 7.6% of construction cost in the NAHB sample, and the line that varies most between two lots. |
| 2. Foundations | The engineer's requirement, not an assumption. Ask what happens if the soil report changes it. | 10.5% in the sample, and soil-dependent. |
| 3. Allowances | Every allowance, as a dollar figure, for tile, fixtures, cabinets, flooring, appliances. | Interior finishes are 24.1% of construction cost. Allowances are where that number is decided later, by you. |
| 4. Exclusions | A written list of what the headline number does not include. | The single most common reason two quotes look different by tens of thousands. |
| 5. Escalation | Who carries the risk if material or labor prices rise before completion, in writing. | Turns a fixed price into an estimate if it is not settled. |
| 6. Exterior specification | Roof assembly, siding product, and the window schedule by size, U-factor and SHGC. | Exterior finishes are 13.4% of construction cost, and this is the part the style pages help you specify. |
| 7. Warranties | The manufacturer's warranty documents and the builder's own written warranty on the workmanship, with its term in years. | They cover different risks. A long product warranty does not cover installation. |
| 8. Schedule | Start date, completion date, and what happens if either moves. | Carrying costs are yours, not the builder's. |
Working through three quotes at once is easier in a grid: put your three quotes into these eight lines and the tool marks the lines each builder left out, with the wording to ask for them. It stays in your browser.
Ask what is excluded. Site work, driveway, landscaping and utility connections are commonly outside the headline number.
Many contracts assume a budget for things like tile and fixtures. If your taste runs above that allowance, you pay the difference later.
Ask who carries that risk, in writing.
Not a show home. A real one, lived in. How it has held up tells you more than any brochure.
Settle the budget before the design. What you can borrow decides which designs are even worth looking at, and finding out early saves months of looking at the wrong houses. Two things are worth doing in this order: get a lender to tell you the number in writing, then decide how much of it you are actually willing to spend, because those are rarely the same figure.
There is no lender link anywhere on this site. We are not in any affiliate program today, and if that ever changes we will label the link and say so before you click it. How we will make money. Nothing on this page is financial advice; a licensed lender or broker in your state is the person to ask.
Once you know the number, put a picture to it. If the style is still open, the modern farmhouse page is where the roof decision is set out against the published GAF and ABC Metal Roofing warranty documents: modern farmhouse exterior ideas, and what each choice costs.
The two datasets on this page are public and were read on 6 September 2026. The 64.4% / 13.7% split and the eight construction stages come from the National Association of Home Builders' Cost of Constructing a Home survey for 2024, published in January 2025 — a survey of builder members, reported as shares of an average, not a price list. The completions, median floor area and sale prices come from the U.S. Census Bureau's characteristics of new housing for 2025. We have not adjusted, blended or projected either set. Everything on this page that is not one of those figures is written as a question to ask a builder, because we have no source that prices a specific house, and any per-square-foot number we invented would be wrong for your county within months. Where we could not find a public source, the page says Not confirmed rather than estimating.
Four choices, under a minute, and a one-page brief you can hand to all three builders.
