A special purpose district is a layer of the NYC Zoning Resolution that sits on top of a lot’s ordinary zoning and adds its own rules. For a house buyer the three that matter most are the Special Natural Area District, the Special Hillsides Preservation District and the Special Coastal Risk District. The numbers below come from the current Zoning Resolution at zr.planning.nyc.gov, which was renumbered after the City of Yes amendments of December 2024.

What is a Special Natural Area District and does it apply to a Staten Island house?

A Special Natural Area District protects aquatic, biologic, botanic, geologic and topographic features and reduces hillside erosion and runoff, under Zoning Resolution section 105-00. It applies to any development, enlargement or site alteration, and the application goes to the City Planning Commission before a building permit is issued, unless an exemption in section 105-021 applies. The Zoning Resolution’s district descriptions name Emerson Hill, Dongan Hills, Todt Hill, Lighthouse Hill and the Central Wetlands area of Staten Island in the NA-1 district and the Shore Acres area in the NA-3 district. The NA-2 description names the Bronx. District boundaries are on the zoning maps, so a neighborhood name is a clue, not an answer.

Can I remove a tree or add a deck in a Special Natural Area District?

Often not without review. Section 105-31 limits removal of trees of 6-inch caliper or more to a few cases, such as building footprints and hazards, unless the Commission authorizes it. Section 105-021 exempts minor accessory structures such as pools, sheds and fences on a lot with an existing home only when grading stays within two feet of cut or fill and no tree of 6-inch caliper or more is removed. A buyer who plans a pool or a driveway regrade should have those conditions confirmed before closing, not after.

What is a Special Coastal Risk District and which Staten Island and Brooklyn blocks are in one?

A Special Coastal Risk District limits rebuilding and enlargement in areas the state has targeted for flood buyouts or that face repeated coastal flooding. Section 137-11 lists five: CR-3 covers the Graham Beach and Ocean Breeze and Oakwood Beach buyout areas on Staten Island, and CR-4 covers Gerritsen Beach in Brooklyn. The other three are in Queens. In CR-3, development and horizontal enlargement require City Planning Commission authorization under section 137-50, and no ancillary dwelling unit is allowed in any coastal risk district under section 137-21.

If you are buying on Staten Island, here is what is different

Staten Island carries the Natural Area districts and a Hillsides Preservation district on top of the coastal one. Under section 119-02 of the Hillsides Preservation district, no development, enlargement or site alteration is permitted in an area of no disturbance, and section 119-01 counts a change of grade of two feet or more as site alteration. The district divides lots into Tier I, with slopes under 10%, and Tier II, with slopes of 10% or more, and Tier II lots face grading limits and authorizations. The Zoning Resolution text does not list neighborhoods for this district, so confirm any Staten Island address on the zoning map rather than assuming a hilltop block is or is not covered. An enlargement that does not increase lot coverage is exempt in both tiers.

If you are buying in Brooklyn, here is what is different

The zoning index lists Natural Area districts with Staten Island and the Bronx in their descriptions, and no Natural Area or Hillsides district description names Brooklyn. Brooklyn’s equivalent risk is coastal: Gerritsen Beach is the only Brooklyn Special Coastal Risk District, CR-4, and section 137-21 limits it to one- and two-family detached or semi-detached homes by lot size. Brooklyn’s other special districts shape building and site design instead. In the Special Ocean Parkway District section 113-12 requires a 30-foot front yard on the Ocean Parkway frontage with no obstructions, and in the Special Sheepshead Bay District section 94-10 requires residential streetwalls to set back at least 10 feet from the street line. Brooklyn buyers should also check the Landmarks Preservation Commission map, which governs historic districts separately.

How do I check whether a Staten Island or Brooklyn house is in a special district before I make an offer?

Enter the address in ZoLa at zola.planning.nyc.gov, which shows zoning districts, special districts, historic districts, FEMA flood zones and tax lots for any lot. Then check New York State DEC wetlands rules: a freshwater wetland of 12.4 acres or more is regulated, with a permit required for activity within 100 feet of its boundary under Environmental Conservation Law section 24-0701, and the size threshold drops to 7.4 acres on January 1, 2028. Ask your attorney to put district status into the contract diligence list.

Who files the paperwork for a special district, a broker or an architect?

An architect, engineer or expediter does, not a broker. The Hillsides Preservation district requires a survey, an architect’s site plan and a landscape architect’s plan filed with the Department of Buildings under section 119-12, and the Natural Area district requires a survey, tree survey, site plan and drainage plan filed with the City Planning Commission under section 105-022. Joseph Ranola is a real estate broker, not a design professional, and Joseph Ranola coordinates those professionals with your attorney before you commit.
