Croydon, PA Building Setbacks & Zoning: Setback Rules (2026)

Setback requirements across Bucks County's 54 municipalities derive from local zoning ordinances enacted under the PA Municipalities Planning Code (MPC, 53 P.S. §10101 et seq.). While setbacks vary by district, common patterns include: Residential R-1 (single-family, low density) — 30-50 ft front, 10-15 ft side, 30-40 ft rear; Residential R-2/R-3 (medium density) — 25-35 ft front, 8-12 ft side, 25-30 ft rear; Village and downtown zones (Doylestown Borough, Newtown Borough, New Hope, Bristol Borough historic cores) — reduced setbacks often 0-10 ft front to preserve historic streetscape; Agricultural (AG) zones in upper and central Bucks — 50-100 ft front, 25-50 ft side, 50+ ft rear with larger minimum lot sizes; Conservation/Watershed (CS) and resource protection zones — enhanced setbacks from streams, wetlands, and slopes; Corner lots — typically two front yard setbacks apply. Accessory structures (sheds, detached garages, pool houses) commonly have reduced rear setbacks of 5-10 feet but must still meet principal structure side setbacks. Decks, patios, and eaves may have allowable encroachments of 2-6 feet. Floodplain overlay zones along the Delaware River, Neshaminy Creek, Pennypack, Tohickon Creek, and other waterways impose additional setbacks per PA Act 166 of 1978 floodplain management and FEMA NFIP. Variance applications require a hardship showing under the MPC §10910.2 and are heard by the municipal Zoning Hearing Board with public notice. Historic district projects (Doylestown, New Hope, Newtown, Bristol) may require HARB approval in addition to zoning compliance.
