What will it cost to build your new home?

Most new homes run roughly $150 to $400+ per square foot in 2026, depending on location, foundation, plan complexity, and finish level. Two identical-square-foot homes can land six figures apart — the number that matters is a line-item estimate tied to your specific plan and ZIP code.

You’ll need the house plan you’re considering and the ZIP code where you plan to build. The easiest way to start is to paste the link to your house plan page; StartBuild reads the square footage, levels, garage, and other plan details from the page. If the page can’t be read automatically, our estimator team pulls the details by hand.

No — get started early with an estimate. Use a published house plan, stock plan, or plan link and StartBuild can usually create a planning estimate from that. If your plan is custom, modified, or one-of-a-kind, you can upload your plans (small extra cost) and we’ll build the estimate from them. Many customers and builders order a new report once their plans are “final,” after modifications or engineering work.

No. StartBuild is a planning estimate — a good starting point you can adjust to make more accurate — not a contractor bid. Use it to understand the likely cost range, compare plan choices, prepare for builder conversations, and spot budget risks before you commit. Before buying land, borrowing money, or starting construction, still confirm real costs with builders, subcontractors, and suppliers.

We work to be conservative and accurate to within about 10%. Your own choices and adjustments affect the line-item costs, and you should still gather real bids from builders, subcontractors, and suppliers before you break ground.

We use a blended database of published national, regional, state, ZIP-code, and actual builder costs for finished homes, updated 10 to 12 times per year. StartBuild has been producing cost-to-build reports for nearly 20 years.

Construction costs are local. Labor rates, material pricing, availability, code requirements, and site conditions vary by market, so StartBuild prices the report to the ZIP code where the home will be built instead of using only a national average.

60+ line items across every phase: site work, foundation, framing, roofing, exterior (siding, windows, doors), plumbing, electrical, HVAC, insulation, drywall, and interior finishes (cabinets, countertops, flooring, tile, trim, paint) — each priced to your ZIP and material choices, with PDF and Excel export.

Yes. The report accounts for more than just heated living square footage. Garages, covered porches, decks, patios, balconies, and similar areas can affect the total project cost, and StartBuild’s estimate reflects those add-ons instead of relying only on a simple cost-per-square-foot number.

Yes — you can add your land costs (purchase or payoff). It can include planning sections for items such as permits, impact fees, site work, excavation, utilities, driveway, septic, well, gas, power, and other site-related costs. These vary widely by lot, so verify them with local contractors, utility providers, and permitting offices.

Yes. The Cost To Build Report is an online tool, not just a static PDF. You can adjust line items, make different material choices and assumptions after purchase, and the report recalculates as you go. Reports include 60 days of online edits and re-exports, and you can export different versions (PDF / XLS) for longer-term use.

A standard Cost To Build Report includes 60 days of online edits plus your exports to PDF and XLS. If your purchase includes BudgetBuilder, access to both the budget and the report extends to 12 months.

BudgetBuilder is for customers who want to move from an estimate to a working build budget. After your Cost To Build Report gives you a line-item starting point, BudgetBuilder lets you upload your own bids, quotes, and product selections so your budget becomes specific to your actual project.

Yes. StartBuild reports export to PDF and Excel, which makes it easier to review the numbers with a spouse, builder, lender, designer, or real estate professional.

Many customers use the line-item report as a starting point for construction-loan conversations because a detailed breakdown is far more credible than a per-square-foot guess. Most lenders also require contractor bids, so confirm your lender’s specific documentation requirements.

Yes. Many builders and customers order more than one report to compare different plans’ estimated construction costs. A StartBuild report helps you see how plan size, shape, foundation type, roof complexity, garage size, porches, and finish level affect the budget. For the clearest comparison, run each plan with the same build ZIP code and similar finish assumptions.

Yes. Owner-builders can use the line-item report as an organized starting budget, then replace estimates with real quotes from subcontractors and suppliers. Because StartBuild is a planning tool, owner-builders should still confirm scope, code requirements, scheduling, insurance, and local labor availability with qualified professionals.

Contact us directly from your specific Cost To Build report using the “Help / Feedback” link. We use technology, but every report is reviewed by a human and messages go to a real person. Give us a little time — we try to be quick, but not always instant. The 60-day edit window and estimator support are there to correct or refine the report when needed.

Because each report is custom-prepared for a specific plan and ZIP code, all sales are final. If something needs correcting, contact the team during the edit window so the report can be reviewed — if you have an issue, let us try to help; we usually can.

No estimate can predict the final contract price exactly. Your final cost depends on your builder, bids, site conditions, material selections, timing, and local market conditions. StartBuild gives you a conservative, line-item planning number that becomes more accurate as you replace assumptions with actual bids and quotes.
