Fence Installation Permits in Philadelphia
Local Rule
Philadelphia Department of Licenses and Inspections (L&I)
Philadelphia splits the building-permit threshold by material: a permit is required for a non-masonry fence over 6 feet, but for a masonry fence the threshold drops to just 2 feet (Administrative Code A-301.2.1). Separately, a zoning permit is required whenever a fence exceeds the Zoning Code limits regardless of material, most commonly triggered in front yards: fences located between the street and the building line are capped at 4 feet and no more than 50 percent opaque, dropping further within 30 feet of an intersection or a shared driveway at least 12 feet wide. Fence posts and gate posts used as architectural features may extend up to 6 inches above the otherwise applicable limit. Properties on the Philadelphia Historic Registry or in the 100-year floodplain always require a building permit regardless of height.

L&I's own FAQ (PG_004) sets a two-tier rule: fences along the street frontage or forward of the house's front wall are capped at 4 ft and must be no more than 50% opaque (no permit needed if compliant); fences from the front wall back, and along the rear line, may be up to 6 ft and fully opaque. Distinctively, fences within 30 ft of an intersection or near a 12-ft-wide shared driveway/alley are further capped at 4 ft and >50% opaque for sightline safety, and non-compliant existing fences are not grandfathered when replaced.
