Philadelphia, PA Fence Regulations: Permit Requirements (2026)

Philadelphia Administrative Code A-301.2.5 specifies when a zoning permit is required and A-301.2.1 specifies when a building permit is required, as summarized in L&I FAQ PG_004. A zoning permit is not required if a fence is at or below the allowable limits of the Zoning Code; if you propose to exceed those limits you must apply for a permit, receive a refusal, and appeal to the Zoning Board of Adjustment. A building permit is required for non-masonry fences (wood, metal, vinyl) that exceed six ft. in height, and for masonry fences (poured concrete, stone) that exceed two ft. in height. The city's Get a Fence Permit page adds that you probably need a permit if the fence will be taller than 6 feet, made of heavy material like masonry or concrete, or located directly along a street front, and that fences more than 50% opaque require a zoning permit. A building permit is always required if the property is on the Philadelphia Register of Historic Places or in the 100-year floodplain. Permits are obtained through L&I, online via eCLIPSE or in person at the Permit and License Center.
