C6-2G Zoning District — New York City

This designation covers a comparatively small slice of the map — roughly 230 tax lots on record — and its building stock reads as some of the oldest in this file. 88% of recorded structures predate 1940, the median construction year is 1910, and just 2% of the stock dates from the 1945-to-1975 boom. Recent construction is modest too: 8% of buildings have gone up since 2000, meaning nearly all of what stands here was already standing well before either era. That combination — a prewar share this high alongside a boom-era share this thin — describes a stock whose building timeline was essentially set before the middle of the twentieth century.

Walk-up apartment buildings are the leading recorded class at 50% of the mix, with mixed residential-commercial buildings at 13% and condominium classifications at 10%. Land use tells a similar story: 73% of lots are recorded under mixed residential-and-commercial use, 12% commercial-and-office, and 6% multi-family walk-up. Residential use overall reaches 83% of lots, and the designation's roughly 230 lots carry 3,634 recorded homes between them — a modest population in absolute terms, but a meaningful one relative to a designation this small.

The lots themselves are small and consistent — a median of 2,513 square feet, with the 90th percentile at 7,044 — and buildings run to a median of 5 stories, with 17% recorded above 6 floors. Neither of the two overlay checks common to these pages turns anything up here: 0% of lots carry a historic-district designation on record, and 0% sit inside the mapped Special Flood Hazard Area. Both readings describe the official maps as they stand, not a guarantee about any one address.

Headroom is broad on paper: 91% of lots record floor area below their allowance, with a median residual of 1.9 FAR. On lots this small and this uniformly built, that gap sits alongside genuinely tight parcels rather than large assemblable sites. The FAR, height, and use rules that govern any lot carrying this designation are set out in the tables above with their citations, and each lot's own recorded detail can be checked individually.

Coverage here is complete rather than partial: none of this designation's recorded stat families are marked null. That matters on a designation this small — with only 230 lots on record, a single unusual parcel could otherwise skew the shares meaningfully, yet the 88% prewar figure and the 91% headroom share both hold across the full set rather than a partial sample. Each of these lots carries its own recorded year-built, class, and floor-area detail, tracked at the individual tax-lot level rather than as a single average.
