New Build Final Inspection — The QC Audit Before You Close

The final and most consequential inspection in the new-construction sequence. This is your buyer's last chance to identify defects, trade damage, and incomplete work before they take possession and the keys change hands. Once closing is complete, every cosmetic issue, every system failure, and every missed warranty item becomes their problem to chase down — usually on their own time, often at their own cost.

Here's what your buyer's inspector will most likely flag at the final inspection. The body of this guide is organized by the major home systems, followed by realtor scripts, how to handle builder pushback, and what comes next in the new-construction sequence.

Why This Inspection Matters

In a competitive market, builders rush. Trade contractors hand off work in sequence, each one creating risk of damaging what came before. The final two weeks of construction are when most cosmetic and finish defects occur — and they're also when builder representatives are most eager to close out the file and move on to the next house.

A Final Inspection is the buyer's independent audit of the finished home, conducted before the final walkthrough with the builder. The findings become the basis of the buyer's punch list — what the builder is expected to fix before or shortly after closing.

Structural Systems

Foundations:

Visible Cracks and Settlement: Inspect interior and exterior for cracks that have appeared since framing. Distinguish between normal shrinkage cracks (hairline, 1/8 inch or less, acceptable) and structural cracks (wider, offset, or growing). Document everything for baseline.
PT Cable Pocket Sealing: Cable pockets at the slab edge must be grouted closed after tensioning. Unsealed pockets expose cable ends to moisture and lead to long-term corrosion and cable failure. A common shortcut that's easy to verify on a new build.
PT Cable Blowouts: Visible cable fractures, protruding cable ends, or concrete failures at pocket locations indicate over-stressing or inadequate concrete strength during tensioning. A significant structural finding.
Honeycombing: Porous, gravelly areas in the slab edge or stem wall caused by inadequate concrete consolidation during the pour. Compromises structural strength and creates moisture intrusion paths.
Slab Finish Quality (Telegraphing Through Floors): Improper trowel work during the slab finish leaves high spots, ridges, and bumps that telegraph through resilient flooring above. Most visible on LVP, vinyl plank, and sheet vinyl installations. The floor surface should be uniformly smooth — visible bumps, ridges along trowel lines, or unevenness underfoot indicates a defective slab finish that's now permanently visible through the flooring.
Cold Joints: Visible lines where the pour was paused too long and the next section didn't bond properly. Creates a permanent weak point in the slab.
Damaged or Missing Parge Coat: The smooth cement coating on the exposed slab edge below the sill plate must be intact. Missing or chipped parge exposes the slab edge to weather and degrades the weather-tight detail.

Grading and Drainage:

Exterior Grading: Final grade should slope away from the foundation at least 6 inches in the first 10 feet. Verify before landscape installation hides the original grade.
Gutter Installation: Verify gutters are properly pitched, downspouts terminate away from the foundation, and splash blocks or extensions are in place.

Roof Covering Materials:

Trade Traffic Damage: Roofs accumulate damage from HVAC, solar, and final-trade contractors walking on them. Look for cracked tiles, scuffed shingles, and damaged flashing.
Drip Edge and Flashing: Confirm drip edge is installed at all eaves and rakes, kick-out flashing is present at roof-to-wall intersections, and chimney/penetration flashing is complete.

Roof Structures and Attics:

Truss and Framing Integrity: Inspect all accessible truss webbing, top chords, bottom chords, and ridge beams for cuts, notches, modifications, or unstamped repair plates. Engineered trusses must not be modified in the field without an engineer's approval — a common production-build shortcut by trade contractors who needed to "make room" for something.
Roof Deck Nailing: Visible from the attic side — verify the roof deck was nailed off correctly to the rafters or truss top chords. Missed nails ("shiners" — nails that miss the framing entirely) and improperly spaced fastening patterns indicate rushed work.
Attic Ventilation: For vented attics, verify gable, ridge, and soffit vents meet the required 1:150 or 1:300 ratio of vent area to attic floor area. Inadequate ventilation drives attic temperatures past 150°F in Texas summers, accelerating shingle deterioration and condensing moisture against the deck.
Spray Foam Encapsulation Installation: For encapsulated attics, verify the foam is applied to proper thickness, reaches all required surfaces (rafters, gable ends, knee walls), and forms a continuous air barrier. Thin spots, voids, and skipped areas defeat the purpose of the system.
Penetrations in Encapsulation: Trade contractors working in the attic after the foam crew (electricians, HVAC, plumbers, satellite installers) commonly create penetrations that never get sealed back up. Verify every penetration through encapsulated foam is properly sealed.
Insulation Coverage (Vented Attics): Where the attic is vented and conventionally insulated, verify R-38 minimum, even coverage, and baffles at soffit vents to prevent insulation from blocking airflow.
HVAC Equipment in Attic: Air handlers, ductwork, and condensate lines installed in the attic must be properly secured to framing — not resting on insulation or top plates. Trade traffic during finish-out commonly knocks equipment loose.
Trade Damage to Framing: Inspect for damaged truss webbing, broken ceiling joists, or compromised framing caused by trade traffic during the build. Easy to spot from below; almost always invisible after drywall finish work covers it.

Exterior Walls, Doors, and Windows:

Siding Installation: Fiber-cement clearances — 2 inches from rooflines, 6 inches from grade, 1/4 inch at horizontal joints with proper flashing. Stucco — verify weep screeds at the bottom and proper expansion joints.
Caulking and Sealing: Every penetration (hose bibs, electrical fixtures, dryer vents, AC line sets) needs proper caulking. Missing or skipped caulking is one of the most common new-construction findings.
Paint Coverage: Verify full coverage at corners, trim returns, and under eaves. Touch-up paint is the builder's responsibility, not the buyer's.
Door and Window Operation: Every exterior door and window opens, closes, latches, and locks properly. Weatherstripping should seal at all four sides. Sliding doors should glide smoothly.

Interior Finish

Walls, Ceilings, and Trim:

Drywall Defects: Visible seams, popped nails, uneven texture, mud splatters, and corner-bead damage. Common from finish-out trade traffic.
Trim Gaps: Baseboards, crown molding, and door casings should have minimal gaps. Where they exist, they should be caulked.
Paint Issues: Roller marks, missed spots, paint on hardware or fixtures, and color variations between rooms or walls.

Flooring:

Trade Damage: Hardwood scratches, tile chips, vinyl tears, carpet stains — all common from final-trade work. Document everything before closing.
Tile and Grout: Cracked or hollow-sounding tiles, missing or uneven grout, and improperly sealed grout in wet areas.
Transitions: Verify proper transitions between flooring types — uneven thresholds, missing T-molding, and unfinished edges.

Cabinetry and Countertops:

Cabinet Alignment: Doors should hang square, drawers should open smoothly, and gaps between adjacent cabinets should be uniform.
Hardware: All knobs, pulls, hinges, and soft-close mechanisms should be installed and functional.
Countertops: Verify proper installation, no chips at edges, sealed seams in stone or quartz, and proper sink and cooktop cutouts.

Interior Doors and Windows:

Operation: Every interior door opens, closes, and latches properly. The single most common defect category on a final inspection.
Window Hardware: Verify all locks, latches, and balance mechanisms function on interior windows. Screens should be present and undamaged.

Electrical Systems

Service Entrance and Panels:

Panel Labeling: All breakers should be properly labeled with the circuits they control.
Service Conductor Sizing: Verify the service entrance and main breaker are sized correctly for the home's load.
Surge Protection: Current code requires a whole-home surge protective device at the service entrance. Frequently missed on production builds — verify it's installed and properly wired.
GFCI on 240V Circuits: Current code requires GFCI protection on certain 240V circuits, including outdoor and garage receptacles. A common production-build miss.
Bonding and Grounding: Verify proper grounding at the service entrance and bonding of metallic systems including gas line, water service, and communications.

Branch Circuits:

All Outlets and Switches Function: Every outlet tested with a polarity tester. Every switch verified for proper operation.
GFCI Operation: GFCIs in kitchens, baths, exteriors, garages, and laundry should test and reset properly.
AFCI Operation: AFCIs in living spaces should trip and reset.
Fixtures and Devices: Every light fixture, ceiling fan, smoke detector, carbon monoxide detector, and doorbell verified to be installed and working.
Exterior Circuits: Outdoor outlets, landscape lighting, and garage door operators verified.

HVAC Systems

Heating Equipment:

System Commissioning: Heating system should be operated through a full cycle. Verify supply temperatures, proper combustion air, and proper venting.

Cooling Equipment:

System Commissioning: Cooling system operated through a full cycle. Verify supply and return temperatures and proper temperature differential.
A2L Refrigerant Sensors (2025+ builds): Homes built with new A2L refrigerant systems should have proper sensor placement, indoor air quality monitoring, and required signage in mechanical rooms.
Condensate Drainage: Primary and secondary condensate lines properly routed, with the secondary terminating in a conspicuous location (above a window) so a clog becomes visible, safety float switch to disable the unit if both primary and secondary drains become clogged.

Duct Systems:

Filter Access: Confirm filter location is accessible and the filter is properly sized and installed.
Register Function: Every supply register has airflow; every return has draw. Inspect for missing dampers, balancing issues, and obvious leaks at takeoffs.

Plumbing Systems

Plumbing Supply:

Water Pressure: Verify static pressure between 40–80 psi. Pressures above 80 psi indicate a failed or absent pressure-reducing valve.
Fixture Operation: Every faucet, shower, tub, and exterior hose bib tested for proper operation and absence of leaks.
Water Heater Setup: Verify expansion tank, temperature setting (120°F default), pan and drain installation, and accessibility for service.
Appliances: Dishwasher, garbage disposal, ice maker line, and any built-in plumbing fixtures verified.

Drains, Wastes, and Vents:

Drain Performance: Every drain tested for proper flow. Slow drains often indicate construction debris in the lines.
Toilet Operation: Every toilet flushed multiple times for proper fill and flush function.
Trap Verification: Confirm all fixtures have proper P-traps installed; verify no S-traps.

Realtor Advice & Strategy

For Buyer Agents

The "Last Chance" Script: This is your buyer's final chance to hand the builder a documented punch list before they sign. After closing, every issue becomes their problem to chase — and the builder's motivation to fix things drops dramatically. We do this inspection so the punch list reflects what your buyer is owed, not just what the builder volunteers.
The "Independent QC" Script: Builders run their own QC walkthroughs, but they're built around the builder's timeline and the builder's interests. We're hired by your buyer, work for your buyer, and the report goes to your buyer. That independence is the point.
The "Trade Damage Audit" Script: The last two weeks of construction are when most cosmetic damage happens — flooring trades scratch finished walls, painters touch up over dirty surfaces, and final-trade contractors damage what came before. We document all of it so your buyer doesn't end up owning someone else's mistake.

For Builders

Expect a Punch List: A thorough final inspection will produce a long list. That's the point. The cleaner the punch list is closed out before closing, the smoother the transaction. Builders who treat this as adversarial create longer closings; builders who treat it as a checklist of items to address create faster ones.
Don't Skip the Pre-Walk: Send your superintendent through the home 24 hours before the buyer's final inspection. Most punch-list items are visible to anyone looking — addressing them proactively shrinks the list the third-party inspector documents.

Handling Builder Pushback

"We already did our QC walk." That walk is performed by the builder, for the builder. A buyer is entitled to independent verification — and the cost is borne by the buyer, not the builder. There's no legitimate reason to refuse access.
"You're slowing down our closing." A final inspection takes 3–4 hours. Most buyers schedule it the same week as closing, with no delay to the calendar. Builders who claim otherwise are usually trying to avoid scrutiny.
"We don't allow third-party inspectors." This is a red flag. Reputable builders permit and even welcome third-party inspections. A refusal is grounds for the buyer to escalate to ownership or reconsider the purchase.
"Your report has too many items." A thorough report will identify many minor cosmetic items alongside the substantive ones. That's the value — surfacing everything for triage. The builder's job is to address each finding; the buyer's job is to verify before closing.

Recommended Ancillary Services

Sewer Scope: Essential on new construction. Construction debris (drywall mud, grout, lumber fragments, fast-food wrappers) is regularly flushed during the build and gets caught in the lateral. Catching it now avoids a $5,000 emergency call later.
Thermal Imaging: Identifies missing insulation, hidden moisture, and HVAC duct leakage that visible inspection can't detect. Particularly valuable on energy-efficient new builds where insulation gaps undermine the energy performance the buyer paid for.
Pre-Closing Reinspection: Once the builder addresses the punch list, a brief reinspection verifies fixes were properly completed before keys change hands.

What Comes Next

The Final Inspection isn't the last opportunity to hold the builder accountable. The 11-Month Warranty Inspection — conducted just before the builder's one-year workmanship warranty expires — is the buyer's final shot at compelling the builder to fix settling cracks, system failures, and latent defects at the builder's expense. Schedule it on the calendar today.

If You're a Buyer Reading This...

A long punch list on your new home is not a sign of a bad builder — it's a sign of a thorough inspector. New construction generates dozens of small defects: trade damage during finish-out, missed caulking, cosmetic flaws, and components that need final adjustment. The builder's warranty covers most of it, but only if you document everything before closing. That's what this inspection delivers.

If you're feeling pressure from the builder to skip the independent inspection because "the builder's QC is enough" — push back. The cost of one inspection is a fraction of what one missed defect costs to fix after closing.
