Why do building inspections happen in stages?
Short answer. Because work gets covered up. Each stage, from footings through framing, electrical, plumbing, mechanical, and insulation to final, must pass before it is enclosed; skip one and you open the walls back up at your own expense.
Work it through
You're the contractor. Pick what you'd do, then see how each choice plays out.
You're managing a full kitchen renovation involving structural, plumbing, electrical, and finish work. The homeowner asks why you can't just get one inspection at the end when everything is done.
"All these inspections slow things down. Can't the inspector just check everything at the final?"
- Correct
Building inspections follow a sequence for good reason: (1) footings/foundation, (2) rough framing, (3) rough electrical, (4) rough plumbing, (5) rough mechanical, (6) insulation, (7) drywall, (8) final. Each inspection must pass before proceeding. The inspector needs to see wiring before it's behind drywall, plumbing before it's enclosed, and framing before it's covered. Skipping to final means opening walls back up. The sequence prevents that waste.
- Wrong
You cannot skip rough-in inspections. If you drywall over uninspected framing, electrical, or plumbing, the inspector will require you to open the walls for inspection — at your expense. The inspection sequence exists because you literally cannot inspect hidden work after it's covered. Trying to skip inspections marks you as either inexperienced or deliberately non-compliant.
