Brand new doesn't mean problem-free. According to the National Association of Realtors, 65% of newly constructed homes have issues identified during inspection, and 24% fail their first inspection entirely. With builders under pressure to meet housing demandsand a construction worker shortage exceeding 500,000—quality control gaps are common. An independent inspection catches defects while they're still the builder's responsibility to fix.
The 4 Inspection Phases: When to Inspect New Construction
Unlike existing homes that get one inspection, new construction benefits from multiple inspections at critical stages—before problems get covered up by drywall and finishes.
Pre-Pour / Foundation
Before concrete is pouredInspects footings, rebar placement, plumbing rough-ins, and soil preparation. Foundation repairs after concrete cures are extremely expensive—catching issues now saves thousands.
Framing / Pre-Drywall
After framing, before drywallThe most critical inspection window. Structural framing, electrical wiring, plumbing lines, HVAC ductwork, and insulation are all visible—and fixable—before walls close up.
Final / Pre-Closing
After completion, before closingFull inspection of finished home—all systems operational, finishes complete. Tests HVAC, plumbing, electrical, appliances, and identifies cosmetic defects before you take ownership.
11-Month Warranty
Before 1-year warranty expiresCatches defects that appeared after move-in while still covered under builder's one-year workmanship warranty. Settlement cracks, HVAC issues, and drainage problems often surface after living in the home.
Top 10 Defects Found in New Construction
These issues appear repeatedly in new home inspections—even from reputable builders. Multiple subcontractors, tight deadlines, and labor shortages contribute to overlooked details.
Grading & Drainage
Water pools near foundation instead of draining away. Causes basement leaks and foundation damage.
Missing GFCI Outlets
Required in kitchens, bathrooms, garages, and outdoor areas. Common code violation in rushed installs.
HVAC Installation Issues
Undersized units, disconnected ductwork, improper refrigerant charge. Causes efficiency and comfort problems.
Window & Door Gaps
Improper installation leaves air gaps, water intrusion paths. Energy loss and potential moisture damage.
Plumbing Defects
Reversed hot/cold lines, loose connections, missing P-traps. Leaks often don't appear until fixtures are used.
Roofing Problems
Missing or misaligned shingles, improper flashing, exposed nail heads. Weather damage risk from day one.
Foundation Cracks
Shrinkage cracks from improper concrete mix or curing. Creates water entry points and structural concerns.
Electrical Defects
Double-tapped breakers, missing covers, reversed polarity. Often from rushing to meet inspection deadlines.
Insulation Gaps
Missing or compressed insulation in walls, attics, crawlspaces. Energy waste and comfort issues year-round.
Appliance Installation
Dishwashers not secured, missing dryer vents, improper gas connections. Safety hazards and premature failures.

Expert Review: Why Municipal Inspections Aren't Enough
Many buyers assume that if a home passed city or county inspections, it's defect-free. This is a costly misconception.
Code compliance doesn't equal quality. A home can pass code while still having workmanship issues, efficiency problems, and defects that affect livability.
With housing demand high, municipal inspectors may spend just 15-30 minutes per inspection. An independent inspector spends 2-4 hours examining your home.
Municipal inspectors work for the jurisdiction, not the buyer. An independent inspector's job is to find every defect and document it for your benefit.
New Construction Inspection FAQs
Do I really need an inspection on a brand new home?
Yes. NAR data shows 65% of new homes have inspection issues, with 24% failing their first inspection. Even with municipal inspections and builder warranties, independent inspectors routinely find defects that would otherwise go unnoticed. The $300-$500 inspection cost is minimal compared to potential repair costs—especially for issues discovered after warranty expiration.
What's the most important phase to inspect?
The pre-drywall (framing) inspection is most critical. This is your only chance to see electrical, plumbing, HVAC, and structural components before they're hidden behind walls. If you can only afford one inspection, choose this phase. If you can do two, add the final/pre-closing inspection.
Will the builder fix issues found in my inspection?
Typically yes, especially before closing. Builders have strong incentive to resolve issues while their crews and equipment are still on site. Present findings professionally as a punch list. Most builders will address legitimate defects, though cosmetic preferences may be negotiated. Document everything in writing.
What's an 11-month warranty inspection?
An inspection performed before the builder's one-year workmanship warranty expires. Many defects—like settlement cracks, drainage issues, and HVAC problems—don't appear until you've lived in the home for several months. This inspection documents issues while the builder is still obligated to repair them at no cost.
How much does a new construction inspection cost?
Final inspections typically run $300-$500 depending on home size and location. Pre-drywall inspections may cost $200-$400. A complete package with multiple phases ranges from $500-$1,000. This investment often saves thousands by catching defects the builder must repair before you take ownership.
Conclusion
New construction homes aren't exempt from defects—in fact, the pressure on builders to meet demand makes thorough inspections more important than ever. Multi-phase inspections catch issues when they're easiest to fix, and 11-month warranty inspections ensure problems are documented before coverage expires. For inspectors, new construction represents a growing service opportunity with clients who understand the value of independent verification.
