Rough-In Inspection

Every finished wall hides wiring, pipes, ducts, and structural connections. The rough-in inspection is the one visit where an inspector can still see all of it. It lands after the shell is up and the trades have run their systems, and before insulation, drywall, or stucco closes anything in.

Arizona cities describe the timing almost identically. Scottsdale calls its framing inspection for the moment when walls, fire blocking, draft stops, and fireplaces are done and the electrical, plumbing, and mechanical are roughed in, "but before any of this work is covered." Phoenix runs a pre-drywall inspection over the same scope. Some jurisdictions break it into separate rough plumbing, rough electrical, and rough mechanical visits, then follow with framing. The rule underneath does not change: no cover-up before sign-off.

What gets checked is what you can never see again. Stud spacing and headers, hold-downs and shear panels, fire blocking, pipe support and slope, gas and water pressure tests, box fill and wire staples, duct sealing, and roof penetrations.

For example, say a drywall crew boards a 2,400 square foot Apache Junction home before the rough-in passes. The inspector arrives, finds nothing left to look at, and fails it. The crew cuts the board back open at every inspected point, waits for a re-inspection, then patches and re-tapes. That is a week of schedule plus labor nobody budgeted. Scheduling is its own trap: Pinal County gives a same-day visit only if you call the inspection line by 6 am, so a late call parks the next four trades for a day.

A rough-in inspection is not the final inspection. Rough-in checks concealed work in the middle of the build. The final checks the finished house at the end and clears the way for your certificate of occupancy. You pass both, in that order.
