Standard Operating Procedure: New Construction Quality Assurance Inspection

This Standard Operating Procedure (SOP) defines the systematic protocol for conducting a comprehensive inspection of a newly constructed residential or commercial property. The objective of this document is to ensure that all structural, mechanical, electrical, and finish components meet industry standards, building codes, and project specifications. This inspection serves as the final gateway to identifying deficiencies before occupancy, protecting both the developer’s reputation and the end-user’s investment.

1. Exterior Envelope and Site Drainage

• Foundation & Grade: Verify positive drainage away from the foundation (minimum 6-inch drop over 10 feet). Check for visible cracks, spalling, or moisture intrusion at the grade level.
• Roofing Systems: Inspect shingles for proper overlap, flashing around chimneys/vents, and secure ridge caps. Ensure gutters are properly sloped toward downspouts and extend at least 4 feet from the structure.
• Siding and Trim: Verify caulking integrity at all windows, doors, and transitions. Check for proper clearance between siding and the finished grade (minimum 6 inches for wood/composite).
• Hardscapes: Ensure driveways and walkways are free of uneven transitions or trip hazards. Verify proper expansion joint installation.

2. Structural and Mechanical Systems

• Electrical: Test all outlets for ground/polarity (using a GFCI tester). Ensure all circuits are clearly labeled in the breaker panel. Verify that exterior outlets are weather-resistant and GFCI-protected.
• HVAC: Verify heating and cooling functionality across all zones. Ensure air filters are clean and accessible. Check that condensate lines are properly piped to the exterior and are not blocked.
• Plumbing: Inspect all visible piping for leaks. Verify that all faucets have adequate pressure and flow. Test water heater relief valves and ensure the temperature is set to appropriate safety levels (120°F).
• Attic & Crawlspace: Inspect insulation R-value consistency. Check for adequate ventilation to prevent moisture buildup. Ensure no structural members have been notched or bored improperly during utility installation.

3. Interior Finishes and Fixtures

• Doors and Windows: Ensure all doors latch securely and sit square in the frame. Check that windows operate smoothly and locks engage properly. Verify that weatherstripping is installed and sealed.
• Drywall and Paint: Inspect walls for "nail pops," tape seams, or uneven texture. Verify consistent paint coverage and absence of "holidays" (missed spots) or drips.
• Flooring: Check for squeaks in subfloors, uneven transitions between rooms, and proper installation of baseboards/shoe molding.
• Cabinetry and Countertops: Verify that drawers and doors are aligned and soft-close mechanisms function correctly. Check that countertops are level and properly sealed at the backsplash.

4. Pro Tips & Pitfalls

• Pro Tip: Always perform the final walkthrough during daylight hours. Artificial lighting hides wall imperfections and paint blemishes that natural side-lighting will reveal immediately.
• Pro Tip: Bring a marble or level. Placing a marble on floor surfaces is a quick, objective way to verify the levelness of the subfloor/finished floor.
• Pitfall - Ignoring Small Flaws: Do not dismiss minor cosmetic issues as "normal settling." Document everything; if it is not documented on the final walkthrough report, it will likely be ignored by the builder post-closing.
• Pitfall - Rushing the Utility Test: Many inspectors turn on a faucet and leave. Let water run for several minutes to check for slow leaks in drain lines and to ensure the hot water temperature remains consistent.

5. Frequently Asked Questions (FAQ)

Q: Should I hire an independent professional inspector if the builder provided their own? A: Yes. An independent third-party inspector has no financial incentive to overlook flaws and provides an objective, unbiased report that serves as your leverage for necessary repairs.

Q: What is the most critical area to inspect in a new build? A: The building envelope—specifically the roof, flashing, and window seals. Moisture intrusion is the number one cause of long-term structural failure and is often the most expensive to remediate.

Q: If I find a major code violation during the inspection, can I force the builder to fix it? A: Generally, yes. In most jurisdictions, the builder is legally obligated to meet local building codes. If a violation is found, present the report to the site superintendent and request a written plan for correction before the final payment or closing.
