Concrete and masonry permits in Tucson
Updated July 2026
Permit rules in the Tucson area depend on two things: whether you are pouring a ground-level slab or building a wall, and whether your address is inside Tucson city limits or in unincorporated Pima County, which are two different authorities with two different processes.
When concrete or masonry work typically needs a permit
A ground-level, uncovered concrete patio or slab is generally the kind of low-risk flatwork that does not trigger a building permit, but confirm the current exemption threshold with the City of Tucson Planning & Development Services Department (PDSD) for your specific project since exemption lists are updated periodically. Walls and fences are a separate rule: Tucson's zoning code caps a standard perimeter-yard wall or fence at 6 feet, and permitting guidance for the area treats 6 feet as the general threshold where a building permit gets triggered, with pool barrier walls and any retaining wall requiring a permit regardless of height. In unincorporated Pima County, a retaining wall needs a permit and structural engineering once it exceeds 4 feet measured from the bottom of the footing, or at any height if it carries a surcharge load such as a driveway or slope above it.
Who is the local authority
For an address inside Tucson city limits, the City of Tucson Planning & Development Services Department (PDSD) is the Authority Having Jurisdiction (AHJ). For an address in unincorporated Pima County (outside city limits, which covers a large share of the greater Tucson area), Pima County Development Services is the AHJ instead, and it has its own separate permitting process and portal. Check your address's jurisdiction before assuming which office applies.
What happens if you skip a required permit
Unpermitted work that should have had a permit can complicate a home sale, may not be covered by insurance if it causes damage, and skips the inspection that confirms the work, especially a wall's structural footing, was built to code. A licensed contractor pulling any required permit is part of what you are paying for.
Frequently asked questions
Do I need a permit for a concrete patio in Tucson?
Usually not for a simple, ground-level, uncovered patio slab. A covered patio, one tied into an accessible route, or one built over living space may fall outside that exemption, so confirm the current threshold with City of Tucson PDSD or Pima County Development Services depending on your address.
Do I need a permit for a block wall in Tucson?
Generally yes once the wall exceeds about 6 feet, which is the standard perimeter-yard height cap in Tucson's zoning code; pool barrier walls and retaining walls need a permit regardless of height. In unincorporated Pima County, a retaining wall needs a permit and engineering once it exceeds 4 feet from the footing, or at any height with a surcharge load.
How do I know if my address is City of Tucson or Pima County?
It depends on whether your property sits inside Tucson's incorporated city limits or in the surrounding unincorporated county area. If you are not sure, City of Tucson PDSD or Pima County Development Services can both tell you which office has jurisdiction over your address.
