Basement Inspection Requirements in Fairfax, VA

Permits are just the start—inspections are mandatory to close them out. Fairfax follows a clear sequence:

Plumbing Groundwork – Must be inspected before the floor is closed.
Trade Rough-Ins – Electrical, plumbing, mechanical, and sprinkler (if applicable) must be approved before framing inspection.
Framing / Building Close-In Inspection – Performed after all trade rough-ins, but before insulation.
Insulation Inspection – Must pass before drywall can be installed.
Final Trade Inspections – Each trade must sign off on its scope of work and pass its inspection before you can proceed to Final Building inpection
Final Building Inspection – Once all trade finals are complete, the building inspector reviews safety items like smoke/CO detectors, egress, and railing compliance.

Each inspection is typically performed by a different inspector, and they do not need to be scheduled the same day, giving you flexibility in keeping the project on schedule.
