What happens during a building inspection?
What the inspector looks for
The inspector's job is to confirm that the work is safe and complies with local building codes. They'll compare what's built to the approved plans and check for common issues like proper wiring, adequate framing, correct plumbing slopes, and fire blocking. They may also verify that materials meet code and that required safety devices (smoke alarms, GFCI outlets) are installed.
Inspections are usually visual and non-invasive. The inspector won't test every outlet or measure every stud, but they will spot-check and may ask you to uncover work if it's not accessible. You or your contractor should be present to answer questions.
- Foundation and footing inspection before pouring concrete
- Framing and structural inspection before drywall
- Electrical rough-in before insulation
- Plumbing rough-in before walls are closed
- Insulation and energy efficiency inspection
- Final inspection after all work is complete
Possible outcomes
If everything passes, the inspector signs off on that phase. If there are minor issues, they may give a 'correction notice' listing what needs to be fixed; you can usually fix it and call for a re-inspection. Major problems can result in a failed inspection, requiring rework and another fee.
Inspectors have the authority to issue stop-work orders if they find unsafe conditions or work done without a permit. They can also require you to hire a licensed engineer to certify structural work. It's best to address any issues promptly to keep your project on track.
Common mistakes
- Not being ready for the inspection—having the work incomplete or inaccessible can lead to a failed inspection.
- Arguing with the inspector instead of asking for clarification on code requirements.
- Assuming the inspector will catch every mistake; they are not a substitute for a qualified contractor.
