Yonkers NY fence permit rules
Yonkers DHB requires a building permit for fence construction. Apply through City Squared at yonkersny.gov/219 (use Chrome). HIC license required — Consumer Protection Bureau: 914-377-3000. Contact DHB at 914-377-6500 with your address and proposed fence height to confirm zoning height limits and any SWM requirements before purchasing materials.
Yonkers' hillside terrain means Storm Water Management considerations can affect fence projects on sloped properties — a fence line that redirects drainage may require SWM review. Contact DHB to confirm before designing. Property line accuracy is critical: Yonkers' dense lot pattern makes encroachment risks significant. The city does not survey lot lines — hire a licensed surveyor or locate survey irons before building on or near a property line. Posts should be set in concrete at 40–48 inches depth to accommodate south Westchester's ~36-inch frost depth. Call 811 before any post-hole excavation.
