Inspection readiness: a pre-call checklist that prevents fails

A failed inspection is the cleanest, most measurable form of wasted day on a residential project. The inspector drives out, spends 20 minutes, writes up a fail, and drives away. Your crew loses minimum a day, often two, sometimes a week if the next available reinspection slot is far out. Multiply by 5-8 inspections on a typical residential project and you start to see why GCs who run a 6% margin spend so much energy on inspection readiness — and why the GCs who don't end up at 1% margin.

The bad news is that most fails are predictable. The good news is that means most fails are preventable, with a pre-call checklist that is specific to the inspection type, the jurisdiction, and the project. Below are the five most common residential inspections and the items that disproportionately drive fails.

Foundation inspection

The first major inspection, usually before backfill. A foundation fail can delay the project a full week because the inspector won't come back until the issue is fixed and they can re-walk.

• Anchor bolt spacing and embedment — most jurisdictions require 4-foot O.C. with a maximum of 12 inches from corners. Walk every wall and verify.
• Footing dimensions — width and depth match the structural sheet. Have the sheet on site to show the inspector.
• Rebar size and spacing — the inspector will ask. Number 4 bar at 16 in O.C. minimum on most residential, often more.
• Frost depth — varies by jurisdiction. The footing has to actually be below frost line. Many fails are because the grade was higher than originally assumed.
• Damp-proofing on the exterior — most jurisdictions require it before backfill. Check the spec.
• Drainage tile around the perimeter, draining to daylight or sump — check the layout.

Framing inspection

After rough plumbing, electrical, and HVAC, before insulation. A framing fail is the second most expensive — usually 2-4 days to fix and re-call.

• Header sizes match the structural drawings — door headers, window headers, beam pockets. Have the structural sheet laminated and on site.
• Joist hangers correct type and properly nailed — inspectors count the nails. Each hanger needs all required nail slots filled with the correct nail size.
• Hold-downs at shear walls correctly installed — this is the single most-failed item on framing inspection in seismic zones.
• Fire blocking at penetrations — between floors, in soffits, around chimneys. Walk every floor.
• Stair rise and run within code — measure every flight before the inspector arrives. 7.75 in max rise, 10 in min run on most codes.
• Egress windows at every bedroom — sill height, openable area, opening dimensions all within code. The spec is typically 5.7 sq ft openable area on second floor, 5.0 sq ft on grade.
• Headroom at stair landings and over the run — 6 ft 8 in minimum.

Rough MEP inspection

Plumbing, electrical, and HVAC rough-in before drywall. Often three separate inspections in residential. Insulation gets inspected separately after.

• Plumbing pressure test held overnight — most jurisdictions require 10-15 psi air for at least 15 minutes before the inspector arrives. Run the test the day before, leave the gauge visible.
• Vent stack sizes and slopes — 1/4 in per foot minimum slope on horizontal drains.
• Electrical boxes at correct height — receptacles at 18 in AFF (varies), switches at 48 in AFF (varies). Inspectors measure.
• GFCI / AFCI breakers in the panel — code requires these in specific circuits. The panel directory should match the actual breakers.
• HVAC duct support — straps every 5 ft on flex, every 10 ft on rigid. Look at every run.
• Smoke detectors and CO detectors located correctly — one in every bedroom, one in the hall, one per floor. Hardwired with battery backup.

Drywall (post-MEP, pre-finish)

Less commonly inspected in residential — many jurisdictions skip this and inspect at final. Where required, the items are:

• Fire-rated drywall correctly installed at required locations — garage-to-house wall, around furnace closet, around water heater closet if gas. Type X minimum.
• Nail and screw spacing per code — typically 7 in on ceilings, 8 in on walls.
• Penetrations through fire-rated walls properly sealed with fire caulk or putty pads — pay attention at receptacles in shared walls.

Final inspection

The last one. Failing this means the homeowner cannot move in on schedule, which has cascading consequences (closing dates, interim housing costs, dispute risk). The items most commonly flagged:

• All smoke and CO detectors operational, batteries fresh, test the devices in front of the inspector if asked.
• GFCI outlets actually function — test each one with the tester button.
• Handrails and guardrails at every required location, at correct heights, securely fastened.
• All required egress paths clear — every bedroom, every basement bedroom especially.
• Address numbers visible from the street — at least 4 in tall, contrasting color, in most jurisdictions.
• Final grade slopes away from foundation 6 in over 10 ft.
• All exterior penetrations properly flashed and sealed.

The pre-call discipline

The single most valuable hour of the PM's week is the hour spent walking the site with the checklist the day before the inspection. Not the morning of. The day before, with time to fix what is found. The pattern that works:

1. Print the checklist for this inspection type, specific to your jurisdiction.
2. Walk the site with the responsible sub, checklist in hand, actually checking each item.
3. Any item that fails — fix it that day, or postpone the inspection call. Do not call an inspector and hope.
4. Photograph the items you fixed for the file. If the inspector questions later, you have documentation.

The math: a 60-minute pre-call walk that prevents a single 2-day re-inspection delay is worth roughly $3,600 in field overhead. Across 6 inspections per project, the ROI on the pre-call discipline is silly.

How AI can generate project-specific checklists

The checklist above is generic. The actual checklist your project needs is specific to (a) the local jurisdiction's code adoption and enforcement pattern, (b) the design of your project, and (c) the historical pattern of fails in your area. AI can generate a tailored list given those inputs.

For example, on a recent project in a coastal Massachusetts town, the inspector was known to be strict on hurricane straps at the roof-to-wall connection. A generic framing checklist wouldn't flag this. A project-specific AI-generated checklist, knowing the jurisdiction and the inspector's historical pattern, would surface it prominently.

How Buildra fits

Buildra generates inspection-specific pre-call checklists from your project address (for jurisdiction-specific rules), your permitted plans (for project-specific items), and aggregated patterns from prior inspections in the same area. The PM walks the site the day before with a list that is already tuned. The fail rate on inspections for projects run on Buildra drops by roughly 70% compared to baseline.
