C6-2 Zoning District — New York City

Of the districts profiled in this set, this one covers the most ground: roughly 690 tax lots citywide, the largest count in the batch. Its development records also show unusually deep recorded headroom: 83% of lots carry floor area below their allowance, and the median residual is 2.1 FAR — a real, buildable-sized gap rather than the near-zero residuals recorded on several other designations profiled alongside it, and a scale of coverage that makes this designation's percentages describe a genuinely large population of lots. A designation covering this much ground records percentages that describe a broad population rather than a handful of outliers.

The recorded classes are led by walk-up apartment buildings at 33%, with condominiums and store buildings each at 12%. Land use runs 52% mixed residential-and-commercial, 16% commercial and office, and 10% multi-family walk-up — a corridor pattern of housing over storefronts at real scale. Residential use covers 70% of the lots, and the file counts 17,544 homes on record, a large total for a designation this size and among the higher unit counts in this set. The remaining recorded building classes fall below the shares reported here individually, consistent with a corridor of housing over storefronts rather than a small number of large sites.

Age on these lots skews prewar, though less uniformly than some: the median construction year is 1911, and 74% of buildings predate 1940. Construction since 2000 accounts for 13% of the recorded stock — the highest recent-construction share among the districts in this batch — while the 1945-to-1975 postwar boom added only 7%. Lots run a median of 2,562 square feet, with the largest lots on record reaching 23,300 square feet, a wider spread than the tightest corridors in this set. That combination of a real prewar majority alongside the highest recent-construction share in this set suggests at least some continued turnover on a fabric that is still mostly old.

A recorded 5% of lots sit inside the mapped federal Special Flood Hazard Area, and a further 5% fall inside a designated historic district — two distinct overlays, each covering a real but modest slice of the parcels. Height runs to a median of 5 floors, with 26% of the recorded stock rising above 6. Two overlays recorded on a designation this large still describe a minority of its lots, worth checking address by address rather than assumed from the designation as a whole. Any one of these 690 lots can be checked against its own governing allowance in the rules tables above, citations included.
