Fence Installation Permits in Phoenix

Local Rule

City of Phoenix Planning and Development Department;

A Phoenix building permit is not required for a fence 3 feet or less in height, measured from final grade to the top of the fence. Fences above 3 feet and up to 7 feet require a permit demonstrating zoning compliance and site drainage only, not full structural review; fences over 7 feet need engineer-stamped structural calculations. Zoning further limits front-yard fences to 40 inches (3 feet for Historic Preservation properties) and side/rear fences to 6 feet, and bars any obstruction over 3 feet on a corner lot within the visibility triangle. Combined fence-plus-retaining-wall height over 9 feet needs zoning approval before a permit is issued.
