New Construction Home Inspection: Cost, Timing, and What to Expect (2026)
Published 2026-06-17 · Updated 2026-07-08
A brand-new house is not a defect-free house. New construction inspections run $300 to $500, the same as any resale, and the two visits that matter most are the pre-drywall walk-through and the final one before you get the keys.
Home size and your ZIP code both move that number. Run yours through the home inspection cost calculator to get a real figure.
Does a new build actually need this?
Yes, and the reasoning surprises people. City building departments do inspect new construction, but that process checks code minimums at set milestones, not the kind of thorough walk-through a buyer's inspector does. Municipal inspectors work for the city, not for you, and they never hand you a report. Subcontractor mistakes and builder shortcuts routinely make it past a code inspection. An independent inspection is a completely separate process built to catch exactly what that one was not designed to catch.
The three inspections worth scheduling
- Phase inspections (during construction). These happen at key milestones: before concrete is poured (foundation and footings), after framing is complete (pre-drywall), and before the final walkthrough. Each phase inspection costs $200 to $400. The pre-drywall inspection is the most valuable because it allows inspection of framing, insulation, wiring, and plumbing before they are hidden behind walls.
- Final inspection before closing. The buyer's inspector walks the completed home before closing and notes any defects, missing items, or work that does not meet specifications.
- 11-month warranty inspection. Most new construction homes come with a one-year builder warranty. An inspection around the 10 to 11 month mark, before the warranty expires, catches issues that have emerged during the first year of occupancy and gives you time to submit warranty claims.
What tends to turn up on a brand-new house
Every system on the resale checklist gets checked here too, but a new-build visit pays extra attention to whether the work matches the builder's own specifications. These are the defects that show up often enough to be worth watching for:
- Improper grading. Soil that slopes toward the foundation rather than away from it is one of the most common new construction defects and can cause water intrusion problems for years.
- HVAC duct leaks. Ductwork is sometimes poorly sealed at connections, leading to energy loss and uneven heating and cooling.
- Missing insulation. Areas where insulation was skipped or compressed during installation are found in many new homes.
- Electrical issues. Missing knockouts, improper ground fault protection, and loose connections are not uncommon even in brand-new construction.
- Roof flashings. Improper flashing around chimneys, vents, and valleys is a frequent finding that can lead to leaks within a few years.
- Plumbing rough-in errors. Drain pipes installed at the wrong slope, missing cleanouts, or improperly secured supply lines are examples of defects that a pre-drywall inspection catches before they are enclosed in walls.
What each visit costs and when to book it
| Inspection type | Typical cost | Best timing |
|---|---|---|
| Pre-pour (foundation and footings) | $200 to $350 | Before concrete is poured |
| Pre-drywall (framing) | $250 to $400 | After framing, rough-in plumbing and electrical complete |
| Final inspection at closing | $300 to $500 | 1 to 2 weeks before close |
| 11-month warranty inspection | $300 to $500 | Month 10 or 11 of occupancy |
For context, our 2026 cost reference puts a location-neutral final inspection on a 1,500 to 2,500 square foot newer home at $300 to $450, which lines up with the final-inspection row above once you factor in your own ZIP code.
Getting the builder to cooperate
Most builders will not fight you on scheduling an independent inspection at the right phase, and one that does resist is worth noticing. Get inspection access written into your purchase contract rather than assumed. Have your inspector coordinate directly with the site superintendent so the crew is at the right stage of the build when the appointment lands.
Once the report is in hand, put every finding in writing and send it to the builder formally rather than relying on a verbal promise from a sales rep. Confirm with the warranty department, in writing, that each item has actually been resolved before you close.
Quick answers
New build vs. resale: does the inspection cover different things?
The same systems get checked either way, but a new-construction visit leans harder on workmanship and whether things match the builder's own specs. Phase inspections are the one thing resale buyers never get, since they catch problems while fixing them is still cheap.
Does the builder's warranty make an inspection unnecessary?
No. An inspection tells you what is wrong. The warranty tells you who fixes it. Skip the inspection and you may not learn about a defect until after the warranty window has already closed.
The builder says the city already inspected everything. Is that enough?
City inspectors confirm code minimums at set milestones. They do not work for you, they do not check every detail, and they hand you nothing in writing. An independent inspection covers exactly what that process was never built to catch.
Things to know
New builds need their own independent eyes on them just as much as a resale does. The pre-drywall visit and the final walk-through are the two worth prioritizing if budget forces a choice. Find an inspector who has specifically worked new construction in your market, and use the calculator above to plan the spend before your closing date arrives.
