Do I need a permit for fence installation or replacement in Unincorporated Maricopa County?
It depends. Whether fence installation or replacement needs a permit in Unincorporated Maricopa County comes down to the details of your project.
A fence over 7 feet is above the height the model residential code exempts, so most jurisdictions that follow that model will require a permit for it. This state does not set that line, so confirm the threshold with your local building or zoning department. Arizona has no statewide residential building code, so fence rules are set by each city, town or county. Standard-height fences are often exempt from a building permit, but taller fences, block or masonry walls, and retaining walls usually require one, and the height threshold and setback rules are local. A fence that also serves as a pool barrier must meet the specific pool barrier requirements (opening size, non-climbable surface, self-latching gate) for the jurisdiction. In Maricopa County, permits outside the cities are handled by the Maricopa County Planning and Development Department, reachable on 602-506-3301 at https://www.maricopa.gov/797/Planning-Development. Its online permit portal is https://www.maricopa.gov/6003/Maricopa-Countys-Permit-Center. This office serves unincorporated Maricopa County. If your address sits inside a city or town, that municipality issues the permit instead. Fences are usually a zoning review rather than a building permit, and the zoning office may be separate from the building office.
