Yes. A brand-new home needs an independent inspection just as much as a 40-year-old one, and in some ways more, because new-construction buyers tend to assume someone else already checked everything. In practice, nobody hired by you has.
Tennessee is one of the fastest-growing construction markets in the country. Subdivisions are going up at full speed around Nashville, Knoxville, and Chattanooga, and speed is exactly the problem: trades are stretched thin, schedules are compressed, and details get missed. After 5,000+ inspections across Tennessee since 2014, the team at Insight Home Inspection Services can tell you plainly: we have never inspected a new build with zero findings.
"But the City Already Inspected It"
Municipal code inspections and a private home inspection answer different questions.
A code inspector checks that specific stages of construction meet the minimum requirements of the adopted building code. Those visits are brief, cover a sampling of items, and happen at fixed milestones. A code inspector is not testing every window, running every fixture, walking the roof, or crawling the crawl space with a moisture meter. Minimum code is also exactly that: the minimum legal standard, not a statement of quality.
A home inspector works for you, evaluates the whole house as a system, and documents anything that is incomplete, damaged, installed wrong, or likely to cause problems, whether or not it technically meets code.
The builder's own quality walk and your pre-closing "blue tape" walkthrough are not substitutes either. You are walking the house looking for paint drips and scratched counters. An inspector is testing systems you cannot see and would not think to check.
What Inspectors Actually Find in New Builds
The findings in new construction are different from older homes, but they are consistent:
- Roof issues: nail pops, damaged or missing shingles, flashing that was never completed around chimneys and dead valleys, and debris left in gutters and valleys.
- HVAC problems: ducts that were never connected in the attic or crawl space, missing insulation on refrigerant lines, condensate drains routed wrong, and systems that were never balanced, leaving one bedroom 8 degrees warmer than the rest of the house.
- Plumbing misses: fixtures never connected to drains (we have seen tubs drain straight into the crawl space), missing insulation on supply lines, reversed hot and cold, and water heaters missing required safety components.
- Electrical loose ends: dead outlets, missing GFCI/AFCI protection, open junction boxes, panel legends that do not match reality, and fixtures that were never wired.
- Grading and drainage: soil sloped toward the foundation, downspouts discharging at the footing, and bare lots that will send the first heavy Tennessee rain straight into the crawl space.
- Crawl space and attic defects: missing vapor barriers, insulation gaps, cut or notched framing members, and construction debris left behind.
- Incomplete finishes: missing weatherstripping, doors out of adjustment, windows that will not lock, and caulk lines that were never finished.
None of this means the builder is bad. It means a house is assembled by dozens of subcontractors in a hurry, and no single person tested the finished product end to end. That is the inspection.
The Three Inspections That Matter for New Construction
Depending on where you are in the build, there are up to three opportunities to catch problems while they are still easy to fix:
1. Pre-drywall inspection. Done after framing, wiring, plumbing, and ductwork are in but before insulation and drywall cover them. This is the only time anyone will ever see the structure and rough-ins exposed. Framing defects, notched joists, wiring and plumbing mistakes, and flashing details cost almost nothing to fix at this stage and a fortune later.
2. Final inspection before closing. The full pre-purchase inspection of the completed home: 400+ items, every system tested, photo-documented report within 24 hours. Schedule it far enough ahead of closing that the builder has time to complete repairs and you have time to verify them at the walkthrough.
3. 11-month warranty inspection. Most builder warranties cover workmanship for one year. An inspection in month 11 documents everything that has settled, cracked, leaked, or failed during your first year, in time to file it as a warranty claim instead of paying for it yourself. If you skip every other date on this list, do not skip this one twice: once the warranty lapses, the same findings become your expense.
What About Radon and Termites in a New Build?
New homes are not exempt from environmental issues. Radon comes from the soil under the house, not from the age of the structure, and East Tennessee's geology produces elevated readings in brand-new subdivisions all the time. New construction can even test higher than older homes because tighter building envelopes trap soil gases. And a termite inspection establishes a clean baseline, which some lenders require even on new builds.
FAQ
Do new construction homes need a home inspection?
Yes. Municipal code inspections check minimum code compliance at a few fixed milestones, and the builder's walkthrough focuses on cosmetics. An independent home inspection tests the completed home as a whole system and consistently finds issues in new builds, from unconnected ducts and drains to roof flashing and grading problems.
What is a pre-drywall inspection?
A pre-drywall inspection happens after framing, wiring, plumbing, and ductwork are installed but before insulation and drywall cover them. It is the only chance to evaluate the structure and rough-in work while it is still visible and inexpensive to correct.
What is an 11-month warranty inspection?
Most builder warranties cover workmanship for one year after closing. An 11-month inspection documents everything that has settled, cracked, or failed during the first year so it can be submitted as a warranty claim before coverage expires.
Should you test a new home for radon?
Yes. Radon comes from the soil beneath the home, not the home's age, and new construction can test higher than older housing because tighter building envelopes trap soil gases. Testing is the only way to know.
