C2-7 Zoning District — New York City

Only about 31 tax lots citywide carry this designation, among the smallest counts of any zoning category covered here. What the records on that small a base show is unusually broad development headroom: 84% of lots carry recorded floor area below their allowance, with a median residual of 3.5 FAR — among the widest recorded gaps of any designation in this profile, though on a base this small, a handful of lots carry outsized weight in every share that follows, so each new filing can move the numbers more than it would on a larger designation. That combination — a small lot count paired with wide recorded headroom — is arguably the single most distinctive fact in this designation's file, more so than its age or its composition.

The recorded building classes are led by walk-up apartment buildings at 39%, elevator apartment buildings at 23%, and mixed residential-commercial buildings at 13%. By land use, mixed residential-and-commercial parcels dominate at 61%, with multi-family walk-up buildings and commercial-and-office parcels each at 13%. Residential lots make up 81% of the total, and the records count 2,475 homes — a substantial figure for so few lots, implying real density where this designation is mapped rather than a scattering of isolated parcels. Walk-up and elevator apartment buildings together account for well over half of every recorded structure on these lots, leaving a smaller residual for commercial and mixed-use buildings.

Lot size spreads widely here: a median of 2,500 square feet against a 90th percentile of 36,897 square feet, one of the widest recorded gaps between typical and large parcels among the designations profiled here. Buildings run to a median of 5 stories, and 17% rise above 6 floors — a mid-rise profile rather than a low one. None of these lots are recorded inside a designated historic district, a 0% share, distinct from designations where landmark review layers on top of the zoning map. That absence means the zoning map itself, rather than a landmark commission, is the only recorded layer of review on these blocks.

The age profile is prewar-leaning but not extreme: a median construction year of 1910, with 74% of buildings predating 1940, 16% dating from the 1945-1975 postwar boom, and 6% built since 2000. Flood exposure is modest, at 6% of lots inside the mapped Special Flood Hazard Area — a fact about the federal map, not a forecast. Taken together, the age and flood figures describe a designation that sits closer to the middle of the range than to either extreme, at least relative to some of the more extreme designations profiled elsewhere. Anyone checking a specific lot under this designation will find its own recorded detail on that lot's page, with the governing FAR and height figures cited in the rules tables above.
