What is a building inspection and when do I need one?
A building inspection is an on-site review by a code official to verify that construction work complies with approved plans and applicable codes. Inspections are required at specific milestones during construction.
Building inspections are required checkpoints during construction where a code official visits the site to verify compliance with approved plans and building codes.
Common inspection types:
- Foundation/footing inspection: Before pouring concrete, after forms and rebar are in place
- Underground plumbing/electrical: Before covering with concrete or backfill
- Framing inspection: After framing is complete but before insulation and drywall
- Rough-in inspections: Electrical, plumbing, and mechanical systems before walls are closed
- Insulation inspection: After insulation is installed, before drywall
- Drywall inspection: After drywall is hung (in some jurisdictions)
- Final inspection: After all work is complete, before occupancy
How inspections work:
1. Schedule the inspection through your building department (often online or by phone)
2. Make sure the work is ready and accessible for the inspector
3. Have your approved plans and permit on site
4. The inspector examines the work against the approved plans and code
5. You receive a pass, conditional pass, or fail result
6. If you fail, correct the issues and reschedule
Tips for successful inspections:
- Do not cover or conceal work before it has been inspected
- Ensure the inspector can safely access all areas to be inspected
- Have your permit card and approved plans visible and accessible
- Be present or have your contractor present to answer questions
- Address all items on the approved plans — inspectors check against what was approved
