Yes, and the reports prove it. We inspect brand-new California homes that have passed every one of their city inspections, and they still come back with findings: bath fans venting into the attic, grading pitched at the foundation, flashing tape that never bonded, insulation with bare patches only an infrared camera catches. None of that fails a code inspection. All of it becomes your problem the day the builder’s obligation runs out, which is exactly why the inspection happens while it hasn’t.
Why New Homes Need Inspections
City code inspectors focus on minimum code compliance. They inspect dozens of homes per day and check that construction meets the baseline legal requirements. A professional home inspector evaluates something different: quality of installation, proper function, and long-term durability.
These are two fundamentally different standards. A home can pass every code inspection and still have significant issues.
Common Defects Found in California New Construction
Our inspectors routinely find the following in newly built California homes:
HVAC Installation Problems
- Ductwork that is disconnected, crushed, or poorly sealed
- Refrigerant lines not properly insulated
- Systems that are undersized or oversized for the space
- Missing return air pathways
Plumbing Issues
- Slow drains caused by improper slope
- Missing P-traps or improperly vented fixtures
- Hot and cold supply lines reversed
- Water heater temperature and pressure relief valves not properly routed
Electrical Defects
- Missing GFCI protection in kitchens, bathrooms, and garages
- Open junction boxes in the attic
- Loose connections at the panel
- Exterior outlets and fixtures not properly sealed
Structural and Exterior
- Grading that slopes toward the foundation instead of away
- Missing or improperly installed flashing at windows and doors
- Stucco cracks from settling that allow moisture intrusion
- Garage firewall penetrations that are not sealed
Attic and Insulation
- Insulation blown or placed incorrectly, leaving gaps
- Missing vapor barriers
- Attic ventilation that does not meet manufacturer specifications
- Bathroom exhaust fans vented into the attic instead of outside
When to Schedule Your New Construction Inspection
The ideal time is before the final walkthrough with the builder. This gives you documented negotiating power to request repairs before you close escrow and while the builder is still contractually obligated to fix defects.
If you have already closed, you still have time, but it is running. California’s Right to Repair Act (Civil Code 895 and following) sets a one-year window on fit-and-finish items for new residential construction, with longer periods for bigger systems, and most builders layer their own one-year workmanship warranty on top. An 11th-month inspection exists precisely to sweep the house before that first year closes. If you go this route, ask for the report tied back to the original 3D tour rather than a fresh, unconnected one. We can re-issue an updated report referencing the same tagged photos and tour, so the builder’s warranty desk sees exactly what changed between move-in and month eleven instead of arguing about which condition existed when.
What Your Inspection Includes
Every Inspection.re new construction California home inspection includes the same comprehensive package as any other inspection:
- Full interior and exterior evaluation of every accessible system and component
- Infrared thermal scan to detect insulation gaps, HVAC duct leaks, and moisture intrusion invisible to the naked eye
- Drone roof inspection to check tile, flashing, and ridge installation from above
- 3D virtual tour with tagged inspection findings for easy reference
- Professional floor plan with LIDAR-measured dimensions
- Same-day report with color-coded severity ratings
The Bottom Line
Skipping an inspection on new construction is one of the most expensive shortcuts a California home buyer can take. Builder quality varies, subcontractors make mistakes, and city inspectors cannot catch everything. A professional inspection gives you a complete, documented picture of your new home’s condition, and the negotiating power to get problems fixed before they become your responsibility.
