The City Plan Department and the Office of Information Technology, on behalf of the City Plan Commission, maintain the official city zoning map. The official map is on file at the City Plan Department, 165 Church Street, 5th Floor and is available for inspection during normal business hours. Maps are no longer available for sale in the office. Instead, the map is available on line in two formats: the citywide zoning map and section sheets. If you need clarification on a zoning boundary, please contact the City Plan Department at (203) 946-6378.
