Buying a newly constructed home feels like a safer bet than purchasing an older property, but don't skip the inspection—builders make mistakes too. New construction inspections focus on different issues than those for resale homes, and knowing what to expect will save you thousands in repairs and headaches down the line.
Why New Construction Inspections Differ
New construction homes haven't weathered seasons, so inspectors can't assess how systems perform over time. Instead, they verify that everything was built to code, installed correctly, and functions as intended on day one. You're looking for construction defects, incomplete work, and manufacturer defects—not the wear-and-tear issues found in older homes.
Builder warranties typically cover structural defects for 10 years and systems for 2–5 years, depending on your state and builder. An inspection documents the condition at purchase, giving you evidence if something fails early and the builder disputes warranty claims.
Timing Matters More in New Construction
Schedule your inspection during the final walkthrough phase, ideally 7–10 days before closing. At this stage, most construction is complete, punch-list items are visible, and you can still negotiate fixes before signing closing documents.
If you inspect too early (during framing), you'll miss finished surfaces and installed systems. If you wait until after closing, you've lost leverage—the builder has already received final payment.
Many builders allow inspections during the "pre-delivery walkthrough," which is your golden opportunity to walk the home with the builder's representative and document issues together.
What Inspectors Check Differently in New Builds
Foundation and framing: Inspectors look for cracks, uneven settling, bowing walls, or improper grading that could cause water infiltration later.
Mechanical systems: Every HVAC unit, water heater, and electrical panel is tested for proper installation and operation—not age-related failure.
Windows and doors: New construction inspectors verify weatherproofing, proper operation, and sealing against air and water intrusion.
Interior finishes: Drywall quality, paint coverage, flooring installation, and trim alignment are checked for builder standards.
Roofing: The inspector verifies proper installation, flashing details, and ventilation—critical because roof leaks often show up years later.
Plumbing: Water pressure, drainage, and fixture function are tested; inspectors look for cross-connections or improper venting.
A comprehensive new construction inspection typically costs $400–$700, depending on home size and location. Some inspectors charge by square footage ($0.15–$0.30 per sq ft) rather than a flat fee.
Key Differences from Resale Home Inspections
| Aspect | New Construction | Resale Home | |--------|-----------------|------------| | Focus | Code compliance, workmanship, defects | Age-related wear, system reliability | | Timeline | Final walkthrough phase | Any time before closing | | Warranty | Builder warranty covers defects | Seller's disclosure, as-is purchase | | Budget negotiation | Builder must fix before closing | Buyer credits at closing | | Inspector expertise | New construction experience essential | General home experience sufficient |
Questions to Ask Your Inspector
Before hiring, confirm they have experience with new construction specifically. Ask if they:
- Are familiar with your builder's typical issues or reputation
- Will attend the final walkthrough with you
- Provide a detailed report identifying code violations versus cosmetic issues
- Can explain builder warranty limitations in writing
Not all home inspectors specialize in new construction—many focus on resale homes. Finding one with new build experience prevents you from paying for an inspection that misses builder-specific problems.
Don't Skip the Structural Phase Inspection
Some buyers hire an additional inspector during framing (before drywall) to verify structural integrity, foundation quality, and proper material installation. This costs $300–$500 extra but catches framing defects impossible to spot after finishing.
If the builder has a poor track record or the home sits in a flood zone, structural inspection is worth the investment.
Get Everything in Writing
Document every issue your inspector finds with photos. Request written estimates from the builder for repairs, then negotiate which ones they'll complete before closing. Don't accept verbal promises—require a written addendum listing all fixes and completion timelines.
If the builder refuses to address significant code violations or structural issues, you have grounds to renegotiate the purchase price or walk away before closing (depending on your inspection contingency clause).

Frequently Asked Questions
Q: Can I use the same inspector my builder recommends? No—always hire an independent inspector with no financial relationship to the builder. Builders' recommended inspectors may minimize issues to keep relationships smooth.
Q: What if the builder won't fix defects I found? Request written repair estimates and credit them against the purchase price at closing, or walk away if defects are structural and your inspection contingency allows it.
Q: Is a new construction inspection worth the cost if the builder provides a warranty? Yes—the inspection documents baseline conditions and identifies code violations that warranties won't cover, protecting your investment.
