New Construction Home Inspection: Cost, Timing, and What to Expect
Do new construction homes need an inspection?
Yes. New construction homes are not immune to defects, and municipal code inspections by local building departments are not the same as a buyer's independent inspection. Builder errors, subcontractor oversights, and items that fall through the cracks of city inspection schedules are found in new homes regularly. A new construction home inspection typically costs $300 to $500, the same as a resale inspection. Use our home inspection cost calculator to estimate costs for your home's size and location.
Types of new construction inspections
- 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 particularly valuable because it allows inspection of framing, insulation, wiring, and plumbing before they are hidden behind walls.
- Final inspection before closing. This is the most common approach. 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 new construction inspections commonly find
- 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 in new homes 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 new construction.
- Roof flashings. Improper flashing around chimneys, vents, and valleys is a frequent finding that can lead to leaks.
- Plumbing rough-in errors. Drain pipes installed at the wrong slope, missing cleanouts, or improperly secured supply lines are examples of plumbing defects found before or after walls are closed.

| 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 |
Working with the builder during inspections
Most reputable builders welcome an independent inspection and will provide access to the home. Builders who resist or discourage a buyer's independent inspection are a concerning sign. Make sure your purchase contract explicitly gives you the right to inspect. Your inspector should coordinate timing directly with the builder's superintendent to ensure the right construction phase is accessible.
After the inspection, document all findings in writing and submit them to the builder formally. Follow up to confirm each item has been addressed before closing. Never accept verbal assurances in place of written confirmation from the builder's warranty department.
Frequently asked questions
Is a new construction home inspection different from a resale inspection? The inspector checks the same systems and components, but new construction inspections often pay extra attention to construction quality, code compliance, and builder specifications. Phase inspections are unique to new construction.
Does the builder's warranty replace the need for an inspection? No. Warranty coverage and inspection findings are separate. An inspection identifies defects; the warranty is a remediation mechanism. You need to identify defects in order to submit warranty claims.
What if the builder says their homes are already inspected by the city? City inspections check code compliance at specific phases. They do not check every detail, are not performed by someone working in your interest, and do not produce a buyer-facing report. An independent inspection is a separate and complementary process.
Bottom line
New construction homes need independent inspections. A pre-drywall phase inspection and a final inspection before closing are the highest-value combination for most buyers. Budget $300 to $500 per inspection and get quotes from a licensed home inspector who has experience with new construction.
