Full Breakdown
Under Town of Babylon Code § 213-63, buildings in the A Residence District, the town's base single-family zone covering unincorporated hamlets like West Babylon, North Babylon, Deer Park and Copiague, are capped at 30 feet or 2 1/2 stories. The Town Board added a narrow exception in 2013: existing habitable structures in the base flood or 100-year flood zone may exceed 30 feet only to the extent needed to meet Chapter 125's FEMA-driven elevation rules, and even then the height cannot exceed those enhanced requirements above grade. Other residential districts (AA, B, C, D) set their own limits elsewhere in Chapter 213.
Violations & Fines
Building without a permit or exceeding the height cap is a zoning violation under Town of Babylon Code § 1-15: a $250-$2,500 fine, up to 15 days jail, with each day a separate offense.
