Many buyers assume a new home does not need an independent inspection because it has never been lived in and already passed municipal code inspections. In practice, new construction goes through dozens of separate trade handoffs — framing, rough electrical, rough plumbing, HVAC, insulation, drywall, roofing, siding, and grading — and each handoff is a place where something can be missed. This guide walks through the pre-drywall inspection, final walkthrough, and 11-month warranty inspection, what inspectors actually look for, and how to handle a punch list once defects are found.
Do You Need an Inspection on a New Home?
Municipal building inspectors check a home for code compliance at specific milestones — framing, rough mechanicals, and final occupancy — but a code inspection is not a quality inspection. A code inspector's job is to confirm the home meets the minimum legal standard to be safely occupied, not to evaluate workmanship, finish quality, or whether something was installed correctly but sloppily. Passing code and being well-built are two different things, and a home can pass every municipal inspection while still having issues an independent inspector would flag immediately.
An independent inspector works for you, not for the builder or the municipality, and that distinction matters more than most buyers realize until they need it. Builders build hundreds or thousands of homes a year using production schedules and subcontractor crews who move fast between job sites; even reputable builders with good track records produce homes with a punch list of items that need correcting. Getting your own eyes on the home at the right stages is one of the highest-value, lowest-cost steps in the entire new construction process.

Pre-Drywall Inspection
The pre-drywall inspection happens after framing, rough electrical, rough plumbing, and HVAC ductwork are installed, but before insulation and drywall close up the walls. This is the single most important inspection stage in new construction because it is the only point where an inspector can physically see the structural framing and mechanical rough-ins. Once drywall goes up, everything behind it becomes expensive and disruptive to access, so problems caught here get fixed cheaply and problems missed here get sealed inside the walls for the life of the home.
At this stage an inspector checks framing squareness and spacing, proper flashing installation around window and door rough openings, HVAC duct routing and connections, electrical rough-in placement, and plumbing rough-in layout. Scheduling access to this stage depends on your contract and the builder's cooperation, so raise it early with your sales representative rather than assuming you will automatically be notified when framing is complete.
Common findings at pre-drywall include missing or improperly nailed structural connectors, duct joints that were never sealed with mastic or foil tape, electrical boxes set at inconsistent heights or depths, and insulation gaps around plumbing penetrations that would otherwise go unnoticed once walls are closed up. None of these issues are unusual for a home under active construction, and most are simple to correct at this stage — the value of the pre-drywall visit is catching them while correction is still a matter of a work order rather than opening a finished wall.
Final Walkthrough Inspection
The final walkthrough, sometimes called a builder orientation or homeowner orientation, typically happens in the days before closing once the home is substantially complete. This is your primary opportunity to walk every room, test every system, and document every defect before you take ownership and before the builder's crews move on to the next home in the community. Anything you do not catch here is harder to get addressed later, so treat this walkthrough as thorough due diligence rather than a quick tour.
Bring a flashlight, a notepad or phone for photos, and plenty of time — rushing the final walkthrough is one of the most common mistakes buyers make. Test every outlet, run every faucet, open and close every door and window, and check every appliance. Anything that does not work correctly or looks incomplete should go on a written punch list before you sign off, and you should attend in person whenever your schedule allows rather than relying solely on a report from someone else.
Pay particular attention to items that are easy to overlook in a quick tour: water pressure and drainage at every fixture, HVAC operation in both heating and cooling modes if the season allows, exterior grading and downspout discharge points, and the condition of driveways, walkways, and any poured concrete. It also helps to bring the sales contract and any selected options list with you, so you can confirm the home was actually built with the finishes, appliances, and structural options you paid for rather than assuming everything matches what was promised.
11-Month Warranty Inspection
Most builder warranties include a one-year workmanship coverage period, and the conventional practice is to schedule a comprehensive inspection around the 11-month mark — late enough for the home to have gone through a full seasonal cycle of heating, cooling, and humidity changes, but early enough to file a warranty claim before the one-year window closes. Issues like drywall cracking from normal settling, seasonal shifts in door and window alignment, or HVAC performance under full summer or winter load often only become apparent after several months of occupancy.
Missing the 11-month window is one of the most common and most avoidable mistakes new construction buyers make, because many warranty structures do not extend workmanship coverage past the one-year mark regardless of when an issue is discovered. Our Builder Warranty Guide covers how the standard 1-2-10 warranty structure works in detail and what each coverage tier includes.
What Inspectors Look For
A qualified inspector evaluates new construction differently than a resale home — there is no deferred maintenance to assess, but there is a full range of trade work to verify for correct, code-compliant, and workmanlike installation. The checklist below covers the categories most commonly reviewed across the pre-drywall and final walkthrough stages.
- Framing squareness and structural member spacing
- Proper flashing around windows and exterior doors
- Insulation coverage and correct R-value by zone
- HVAC ductwork sealing and connections
- Electrical panel labeling and breaker organization
- GFCI outlets installed in kitchens, bathrooms, and other wet areas
- Plumbing supply line pressure test
- Site grading and drainage sloped away from the foundation
- Roof flashing and shingle installation quality
- Gutter attachment and downspout placement
- Exterior caulking around penetrations and trim
- Drywall seams, nail pops, and finish quality
- Door and window operation, alignment, and locking hardware
- Foundation for visible cracks or settling
- Garage door operation and safety reversal sensors
- Smoke and carbon monoxide detector placement
- Water heater installation and venting
- Attic ventilation and baffles
- Siding installation and seams
- Site cleanup and construction debris removal
This list is not exhaustive, and a qualified inspector will adapt it to your specific home type, climate, and the systems installed. What matters most is that each item is checked by someone working solely on your behalf, using the same rigor they would apply to a resale home.
Choosing the Right Inspector
Not every home inspector has direct new construction experience, and the skill set is not identical to inspecting a resale home. Look for an inspector who is licensed in your state, carries errors and omissions insurance, and can speak specifically to pre-drywall and rough-in inspections rather than only final walkthroughs. Ask how many new construction inspections they perform annually and whether they provide a written report with photos for every stage you book.
It is also worth asking directly whether the inspector has worked in communities built by your specific builder before, since familiarity with a builder's common trade partners and typical trouble spots can make an inspection more efficient and more targeted. Avoid using an inspector recommended exclusively by the builder's sales office without independently verifying their credentials — an inspector should be accountable to you, not to the builder's referral relationship.
Compare pricing and scope across two or three inspectors before booking, and ask specifically what equipment they use — thermal imaging cameras and moisture meters can reveal insulation gaps and hidden leaks that a purely visual inspection would miss. A good inspector will walk you through their findings in person at the end of the visit in addition to providing a written report, so you leave with a clear understanding of what needs attention rather than a document full of technical language you have to decode on your own.
| Inspection Stage | Timing | What It Covers |
|---|---|---|
| Pre-pour / foundation | Before concrete is poured | Footing depth, rebar placement, and foundation forms |
| Pre-drywall | After framing and rough-ins, before drywall | Framing, electrical, plumbing, and HVAC rough-ins |
| Final walkthrough | Days before closing | Finishes, system operation, and overall punch list items |
| 11-month warranty | Around month 11 of ownership | Seasonal settling, HVAC performance, and warranty-eligible defects |
Common New Construction Defects
Some defects in new construction are cosmetic and easily corrected, such as paint touch-ups, minor drywall nail pops, or scuffed trim from move-in traffic. Others are more significant and worth taking seriously, including HVAC systems that are undersized or improperly balanced for the home's layout, plumbing connections with slow leaks that only become visible after water runs through the system repeatedly, and grading that does not properly direct water away from the foundation.
Window and door misalignment is one of the most common defects found at the 11-month mark, since seasonal temperature swings can reveal framing settling that was not apparent at closing. Electrical issues such as mislabeled panels or missing GFCI protection in wet areas are also frequently caught by inspectors rather than by buyers themselves, since these issues are not always obvious during normal use. None of this means a particular builder is doing something wrong — it reflects the reality that dozens of trades touch a home during construction, and inspections exist precisely to catch what gets missed along the way.
Builder Punch Lists
A punch list is the itemized record of defects and incomplete items generated during the final walkthrough (and, separately, during the 11-month warranty inspection) that the builder is contractually obligated to address. Every item should be documented in writing with photos and a description specific enough that there is no ambiguity about what needs correction, and you should request a target completion date for each item rather than accepting an open-ended commitment.
Once the builder reports an item complete, do a follow-up walk to verify the work before considering it closed — do not rely solely on a phone call or email confirmation. If a builder is slow to respond or disputes an item you believe is legitimately covered, review your purchase contract and warranty documents for the specific language governing punch list and warranty claim timelines, and put your concerns in writing. Understanding the contract terms you agreed to before closing makes these conversations far easier; our Builder Contract Guide covers deposit, change-order, and completion terms worth reviewing before you sign.
