How Much Does It Cost to Build a House? (Price Guide)

The cost to build a house depends on size, location, finishes, and how the project is run. Two numbers often get mixed up online: what it costs to build a home, and what a newly built home sells for. They are not the same, and this guide keeps them apart.

Figures below come from HomeLight, Opendoor, and the U.S. Census Bureau, with a check date of Oct 11, 2026. The headline range excludes the lot. Your own budget will also need land, utility hookups, permits, and a contingency fund for surprises.

The table shows several views of the total. The NAHB figures describe an average new single-family home of 2,647 square feet, and one row adds the lot to the construction cost. The lot row shows how widely land prices run, which is why many builders and lenders treat land as a separate line.

The headline range and the NAHB construction figure do not match. The gap may come from house size, sample, and what each source counts as construction, since the published guides do not break it down. The NAHB figure is for a specific average home size, while a wider range covers small and large homes in many regions.

Price per square foot is the quickest way to sketch a budget. Multiply by the square footage you plan to build, then add land and extras.

Per-square-foot figures are a rough guide. They tend to be lower for simple, larger rectangular homes and higher for small homes, custom designs, and kitchens and bathrooms packed into limited space, because those rooms cost more per foot than bedrooms. Modular construction is listed as a separate, lower range, but you still need a site, a foundation, delivery, and a crane for set day, which are often priced apart.

The Census Bureau tracks the price at which newly built houses sold. These are sale prices, not construction costs. A sale price typically includes the land, the builder's overhead and profit, financing costs, and local fees. It does not tell you what it would cost to build a house on a lot you already own.

Use these numbers to compare against the price of existing homes in your area. Do not use them to estimate your build budget. If you are deciding between buying new and building, compare the full cost of each, including land, closing costs, and the time you will wait.

• Size and layout. More square footage means more materials and labor, though cost per foot can fall with a simpler shape.
• Location. Labor, permits, and material prices differ by region. Land prices differ even more.
• Site conditions. Sloped, rocky, or wet lots may need grading, retaining walls, or a special foundation.
• Utilities. A lot without water, sewer, or power connections can add substantial cost for wells, septic systems, or line extensions.
• Foundation type. Slab, crawl space, and basement foundations cost different amounts.
• Finishes. Flooring, cabinets, countertops, windows, and fixtures can move the budget more than the structure itself.
• Builder type. A production builder, a custom builder, and an owner-managed project each price the work differently.
• Permits and fees. Many jurisdictions charge permit, impact, and inspection fees. Check what your local building department requires.

Published figures are hard to compare because each one defines the job differently.

Some guides include only the construction of the house, while others include land, site work, and soft costs such as design fees. One may be based on contractor quotes and another on national builder surveys. Check whether a number covers the lot, utilities, landscaping, and the driveway before relying on it.

• Land purchase and closing costs
• Architect or designer fees, and engineering for the foundation
• Survey, soil testing, and permits
• Utility connections, septic or well
• Driveway, landscaping, and fencing
• Construction loan interest, which is paid while the house is being built
• Appliances and window coverings
• A contingency fund for price changes and change orders

A production builder uses set plans and sells at a fixed base price with option packages. Semi-custom lets you change a plan, and custom starts from your own design. Each step gives you more control and generally adds cost and time. A fixed-price contract can reduce surprises, but read what is excluded. An allowance for finishes that is set too low can leave you paying more later.

• Is the lot, site work, and utility hookup included?
• Is the quote fixed price or cost plus, and what is the allowance for finishes?
• What is the payment schedule, and what inspections are tied to each payment?
• How does the contract handle change orders and delays?
• Is the builder licensed and insured in your state? Ask to see proof.
• What warranty does the builder provide on structure and systems?

For financing, a construction loan works differently from a mortgage. Talk to a licensed lender about terms before you commit.
