Builder Contracts Explained: What New-Construction Buyers Should Know

Buying a brand-new home means signing a document that looks very different from a standard resale contract. A builder purchase agreement is typically drafted by the builder's attorneys to protect the builder, so understanding how it works before you sign is the single best way to protect your money, your timeline, and your expectations. This guide explains the key sections of a new-construction contract, where buyers have room to negotiate, and the questions to ask before you commit.

How a Builder Contract Differs From a Resale Contract

A resale contract is usually a standardized state or association form that both sides are familiar with. A new-construction agreement is often a custom document written for the specific builder, and its terms tend to favor the company that wrote it. Common differences include:

• Non-standard forms that may lack the buyer protections found in typical resale contracts.
• Larger, sometimes non-refundable deposits tied to construction milestones.
• Broad builder discretion over materials, substitutions, and completion dates.
• Limits on inspections and contingencies that buyers would normally expect.

Because the contract sets the rules for the entire build, read every page and ask for written clarification on anything vague. Consider having a licensed real estate attorney review it; builder contracts are one of the clearest cases where professional review pays for itself.

Deposits and Earnest Money

New-construction deposits are frequently larger than resale earnest money and may be released to the builder during construction rather than held in escrow. Pay close attention to:

• How much you must put down and when additional deposits are due.
• Whether deposits are refundable if the deal falls apart, and under what conditions.
• Who holds the funds — an escrow agent, a title company, or the builder directly.

Understand that money released to fund construction may be difficult to recover. For the fundamentals of how good-faith deposits work, see our guide to earnest money.

Allowances, Upgrades, and Change Orders

Much of a new-construction budget lives outside the base price. Builders set allowances — dollar amounts budgeted for items like flooring, cabinets, or fixtures. If you choose options that cost more than the allowance, you pay the difference, and those costs can add up quickly.

• Review every allowance and ask what the base-level selections actually include.
• Get upgrade pricing in writing before you finalize selections.
• Understand the change-order process — how to request changes, deadlines for locking selections, and any administrative fees.
• Confirm what happens to unused allowance dollars (some builders do not credit them back).

Ask for a complete, itemized selection sheet so the final price reflects your real choices rather than a stripped-down base model.

Timelines, Delays, and Completion Dates

Construction schedules slip for many reasons, from weather to supply chains. Builder contracts usually give the builder generous leeway on the completion date, so look for:

• An estimated versus guaranteed completion date, and the difference between them.
• Delay provisions — what counts as an excusable delay and whether there is any outside date after which you can cancel.
• Remedies for the buyer if the home is not finished within a reasonable window.
• Interest-rate and lock implications, since long delays can affect your financing. Review your financing timeline alongside the build and keep your lender updated; our mortgage pre-approval guide explains how to stay ready.

Build a realistic buffer into your own moving and lease plans, and avoid giving notice on your current housing until the completion date is firm.

Inspections, Warranties, and Final Walkthrough

A common misconception is that a new home does not need an inspection. It does. Even with municipal code inspections, an independent inspection can catch issues before you close. Some builder contracts restrict third-party inspections, so confirm your rights in writing.

• Independent inspection: Hire your own inspector at key phases if the contract allows it. See our home inspection guide for buyers for what to expect.
• Final walkthrough and punch list: Document every unfinished or defective item before closing. Our new-construction punch list guide walks through this step by step.
• Builder warranty: Most new homes come with a limited warranty covering workmanship, systems, and structure for varying periods. Read what is and isn't covered in our new-construction home warranty guide.

Financing and Lender Clauses

Many builders offer incentives to use their affiliated lender or title company. These incentives can be valuable, but you are generally free to shop and compare. Review:

• Whether incentives are tied to using the builder's lender and how much you'd forgo by using another.
• Rate-lock terms, especially for longer build timelines.
• Appraisal provisions — what happens if the appraisal comes in below the contract price.

Compare the total cost of financing, not just the headline incentive, and get competing quotes before deciding.

Questions to Ask Before You Sign

• Is my deposit refundable, and who holds it?
• What is the guaranteed outside completion date, and what are my remedies for delays?
• Can I bring my own inspector, and at which stages?
• What exactly does the base price include versus upgrades?
• What does the warranty cover, for how long, and how do I submit claims?
• Am I required to use the builder's lender or title company?

If you are comparing new construction against existing homes, you can browse options and list your current property when you're ready to buy or create a listing.

Frequently Asked Questions

Can I negotiate a builder's contract?

Often yes, though builders are typically less flexible on base price than on upgrades, closing-cost contributions, or specific contract terms. Everything you negotiate should be documented in writing and signed. A real estate attorney can help identify which clauses are reasonable to request changes to.

Do I need a home inspection on a brand-new house?

Yes. Municipal inspections verify code compliance but are not a substitute for an independent inspection focused on your interests. If the contract limits inspections, ask to add the right to a third-party inspection before signing.

What happens to my deposit if construction is delayed?

That depends entirely on your contract. Some agreements allow cancellation with a deposit refund after a certain outside date; others give the builder broad leeway. Read the delay and termination provisions carefully before you sign.

Is the builder's warranty enough protection?

A builder's limited warranty covers defined items for defined periods, but coverage and claim procedures vary widely. Review the warranty document in full, keep your punch list and closing records, and consult a professional about gaps specific to your purchase.
