A lot of buyers assume that a brand-new home doesn’t need an independent inspection. The city inspected it, the builder signed off on it—what’s left to check? Quite a bit, as it turns out.
A new construction home inspection is different from a city permit inspection, and having an independent inspector review your home at key stages of the build is one of the most practical things you can do to protect your investment.

Do You Need a Home Inspection for New Construction?
You’re not legally required to hire an independent inspector on a new build. But the fact that inspections aren’t mandatory doesn’t mean they’re unnecessary. City inspections verify code compliance—they are not a comprehensive quality review. The builder’s internal quality control exists to serve the builder’s interests. Neither one is a substitute for an inspector working on your behalf.
The independent inspector’s job is to find what the other two might miss —or what they weren’t specifically looking for. That’s a meaningfully different mandate.

Timing matters with a new construction home inspection. The most valuable inspection points are before walls are closed and before you take ownership—not after you’ve already moved in and the builder has moved on to the next project.
When to Inspect a New Construction Home
The pre-drywall inspection is the most important one. Once drywall goes up, framing, wiring, ductwork, and plumbing are all hidden. Any issues in those systems become significantly more expensive to access and correct after the walls are closed.
How many inspections should you get? At a minimum, a pre-drywall inspection and a final inspection. If budget allows, adding the pre-pour and 11-month warranty inspections gives you comprehensive coverage across the entire construction and early ownership period.

The pre-drywall inspection happens after framing is complete and all rough-in systems (plumbing, electrical, and HVAC) are installed, but before insulation and drywall close everything up. It’s the only point in the build where an inspector can physically see and evaluate all of those systems at once.
Issues found at this stage are almost always less expensive to fix than the same issues found after drywall. A misrouted drain line, an improperly fastened beam, or a duct connection that wasn’t sealed—all of those can be corrected in a few hours before walls close. After drywall, the same corrections require cutting into finished surfaces, patching, repainting, and rescheduling.
Pre-Drywall Inspection for New Construction Homes
City inspections at this phase cover code compliance, not workmanship quality. An independent inspector looks at both.

The final walkthrough happens when construction is complete, before you close on the home or take possession. This is your opportunity to document any outstanding items that need to be corrected before the builder considers the project done.
The items that come out of the final walkthrough become the builder’s punch list—a documented list of corrections to complete before closing. Take this process seriously. Walk every room, test every outlet, run every faucet, and open every door and window. Bring a checklist and take photos of anything you want documented.
In California, it’s common practice to give the builder a reasonable window to complete punch list items before closing. What’s not reasonable is closing before the list is done and hoping items get resolved after the fact.
Final Walkthrough Inspection Checklist for New Construction
For more on how the final inspection fits into the permit process: What Are Phase Inspections for New Construction Homes?
New homes are not defect-free. Independent inspectors on new construction projects routinely find issues that city inspections didn’t flag and that builder walkthroughs missed. Here’s what tends to come up.
Missing blocking, improperly sized headers, inadequate fastening at critical connections—framing errors that don’t rise to the level of a code violation can still affect long-term performance, particularly around doors, windows, and load-bearing walls.
Duct connections that aren’t properly sealed, equipment that’s undersized for the home’s square footage, or registers placed in locations that create uneven comfort across the house. HVAC problems that go undetected at move-in tend to become more expensive and frustrating over time.
Supply or drain connections that weren’t fully tightened, drain slopes that are too shallow for reliable drainage, or venting configurations that don’t meet code. Small plumbing issues can cause water damage if left unaddressed.
What a New Construction Home Inspector Usually Finds
Missing outlets in locations required by code, circuits that share loads they shouldn’t, or panel labeling that doesn’t accurately reflect what’s connected. These are common and generally straightforward to correct before walls are finished.
Paint that wasn’t properly prepped, grout joints that are inconsistent, flooring that has visible gaps or transitions that weren’t finished cleanly. These are easier to document and correct before closing than after you’re already living in the home.
Most new construction homes come with a builder warranty that covers workmanship and materials for at least one year. The 11-month warranty inspection is a new construction home inspection scheduled before that warranty expires, giving you the opportunity to document any defects or issues that have emerged since move-in.
Settlement is normal in new construction. What you’re looking for at the 11-month mark are issues that go beyond typical minor settling—persistent cracks, doors that no longer close correctly, water intrusion signs, or mechanical systems that aren’t performing as expected. A qualified inspector can help you distinguish between what’s normal and what the builder needs to address under warranty.
Scheduling this inspection at month 10 gives you time to document findings and submit a warranty claim before coverage expires.

Independent inspections are a small cost relative to the value of catching a problem early versus dealing with it after closing.
The buyer typically pays for independent inspections. They are not part of the builder’s contract and are not covered by permit fees. Some buyers try to negotiate inspection access as part of the purchase agreement, which is worth doing on a new construction transaction.
The value case is straightforward. A pre-drywall inspection that catches a significant HVAC routing issue before walls close saves the cost of opening and repairing finished surfaces later. A final inspection that documents punch list items gives you legal standing to require corrections before closing. The 11-month inspection protects your warranty rights before they expire. Bundling all three stages with a single inspector who knows your project from the start typically costs less than hiring separately for each one.
Not every home inspector has experience with new construction. Inspecting a completed existing home is a different skill set than evaluating a home at multiple phases of construction. Here’s what to look for.
Cost of New Construction Home Inspection
Ask specifically whether the inspector has done pre-drywall and phase inspections on new builds, not just final inspections on completed homes. The pre-drywall inspection in particular requires familiarity with rough-in systems and structural framing that not every general inspector has.
Confirm that the inspector is comfortable visiting the site at multiple stages and understands the sequencing of new home construction phases. An inspector who only does final walkthroughs is not the right choice for a full new construction engagement.
Ask to see a sample report from a new construction inspection. A good inspection report is specific, well-documented, and includes photos of every issue identified. Generic language and vague descriptions are a sign the inspector isn’t thorough enough for this type of work.
In California, home inspectors are required to carry errors and omissions insurance and general liability coverage. Confirm both before hiring. Licensing requirements vary by jurisdiction, so verify what applies in your area.

How to Choose an Inspector for New Construction Homes
Yes. A new construction home inspection is one of the most cost-effective steps you can take when building or buying a new home. City inspections verify code compliance. Builder walkthroughs serve the builder’s interests. An independent inspector works for you, and they’re looking for things the other two aren’t specifically tasked with finding.
The pre-drywall inspection is the highest-value stop in the process because it’s the only time all of the structural and mechanical systems are visible at once. The final inspection protects your closing position. The 11-month warranty inspection protects your rights before builder coverage expires. Together, those three stages give you meaningful oversight across the entire new home process.

It’s not legally required, but it’s strongly recommended. City inspections only verify code compliance. Builder inspections serve the builder’s quality control process. An independent new construction home inspection is the only review conducted specifically on behalf of the buyer.
Should You Get a New Construction Home Inspection?
The most important timing is the pre-drywall stage, before insulation and drywall close up the framing and rough-in systems. A final inspection before closing is also essential. If the home comes with a builder warranty, scheduling an 11-month warranty inspection before coverage expires is a smart additional step.
At a minimum, a pre-drywall inspection and a final inspection. Adding a pre-pour inspection and an 11-month warranty inspection gives you comprehensive coverage. Some inspectors offer bundled packages that cover all stages at a lower combined cost than booking separately.
It depends on the stage. A pre-drywall inspection covers framing, plumbing rough-in, electrical wiring, and HVAC ductwork. A final inspection covers all finishes, fixtures, system operation, and overall completion. An 11-month warranty inspection focuses on settlement, latent defects, and system performance after a season of use.
The buyer pays for independent inspections. They are not included in the builder’s contract or permit fees. Some buyers negotiate inspection access rights into the purchase agreement before signing, which is a reasonable ask on any new construction transaction.
