Mesa, AZ Building Safety: Building Inspections (2026)

Section 4-1-5(B) lists eleven required inspection types. Footing and foundation inspections happen after excavation and reinforcing steel placement but before concrete is poured; concrete slab and under-floor inspections happen after in-slab reinforcing and utilities are in place but before concrete or subfloor sheathing goes down; rough plumbing, mechanical, gas, and electrical inspections happen before covering and before the framing inspection; framing and masonry inspections happen after the roof deck, framing, fireblocking, and rough utilities are in place and the roof is loaded with covering material; and the final inspection happens only after all work required by the permit is complete.

It is the permit holder's duty to notify the Director when work is ready and to provide access for each inspection (§ 4-1-5(E)). Under the Approval Required provision, work cannot proceed beyond the point marked by each successive inspection until the Director signs off, and any noncomplying portion must be corrected and stays uncovered until authorized; a failed inspection can trigger additional fees under the City's Schedule of Fees and Charges (§ 4-1-5(F)). No occupancy or use is allowed until final inspection and approval are complete, and a gas piping installation cannot be turned on by the utility until the Director issues a certificate of inspection (§ 4-1-5(G)).
