C4-2F Zoning District — New York City

Few designations on the zoning map are this small. Citywide, only 8 tax lots carry it, which means every percentage below describes a handful of parcels rather than a citywide pattern — read each figure as a count, not a trend. The records also carry no reliable year-built or building-height coverage for this designation, so no construction-era claim can be made honestly here; where most designations open with a construction date, this one cannot, and that absence is worth stating plainly rather than glossing over. What the file behaves like, instead of an occupied residential or commercial category, is a residual or transitional map designation sitting mostly outside the built city.

What the records do show is dominated by vacant ground rather than standing structures. Vacant land accounts for 63% of the recorded land use and 63% of the recorded building classes, with mixed residential-commercial and commercial-and-office uses each recording 13% of the remainder of the land-use file. Condominium buildings make up 25% of the recorded building classes on the small share of these lots that carry any structure at all. Only 13% of the lots are recorded as residential, and the file counts just 340 units in total across the entire designation — a small number that fits a map category built around open or transitional parcels rather than housing stock.

The parcels themselves are unusually large, which is consistent with ground held for future use rather than parceled for individual buildings. The median lot runs 14,800 square feet, and the 90th percentile reaches 99,015 square feet — sizes that belong to assemblages or open tracts rather than standard building lots in most residential or commercial districts. None of the 8 lots are recorded inside a designated historic district, and none sit within the mapped federal Special Flood Hazard Area, though with a sample this small even a single lot's status can shift the percentage considerably.

The development ledger is as extreme as everything else in this file: 100% of these lots record floor area below their allowance, with a median residual of 6 FAR. On parcels this large and this vacant, that gap describes ground that has not been built at all rather than structures sitting under capacity. It is a reminder that a headroom percentage means something different depending on how many lots and how much land sit behind it.
