Do I need a permit for fence installation or replacement in Phoenix?

Permit may be required

It depends. Whether fence installation or replacement needs a permit in Phoenix comes down to the details of your project.

Phoenix requires a permit for any fence or wall taller than three feet; requirements come from both the Phoenix Building Construction Code and the Zoning Ordinance. Retaining walls and any structure in the public right-of-way have separate requirements (Retaining Wall Application and right-of-way guidance). A wall that also serves as a pool enclosure must meet the stricter Phoenix pool barrier requirements (height and self-latching gate), not just the general three-foot fence rule. 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.
