R3-2 Zoning District — New York City

Of the ten designations profiled in this batch, none records a narrower development margin than this one: only 56% of lots carrying it show any floor area below their allowance, and where they do, the median residual is just 0.1 FAR — the tightest recorded gap in this set. Read together, those two figures describe a stock that has already built out close to whatever capacity its lots carry on record, leaving comparatively little of the recorded room that shows up more generously elsewhere in this bracket of the zoning map, where wider recorded headroom is the norm.

The designation is mapped across roughly 62,000 tax lots citywide, one of the larger footprints in this batch. One-family homes lead the recorded building classes at 59%, two-family homes follow at 27%, and vacant land accounts for 3%. Land use tells much the same story: one- and two-family use covers 86% of lots, with multi-family walk-up use and vacant land each recorded at 3%. Overall 92% of lots are coded residential, and the file counts 132,165 homes across the designation — one of the larger recorded populations in this set, reflecting both the footprint's size and the record of what actually stands on it.

The construction record centers on the middle of the twentieth century: a median year of 1950, with 40% of recorded buildings predating 1940 and 24% dating from the 1945-1975 postwar boom. A further 10% of buildings have gone up since 2000, a real if modest layer of recent construction on top of an otherwise mid-century stock that shows no single era dominating quite as thoroughly as in some neighboring designations.

Lots run compact: a median of 2,500 square feet, with the 90th percentile reaching 5,000 square feet. Buildings rise to a median of 2 stories, and 0% of recorded buildings climb above 6 floors. Flood exposure is limited — 3% of these lots sit inside the mapped federal flood zone — one of the lower shares in this batch. None of this designation's recorded stat families come back nulled for coverage, so the tight headroom figures above reflect a complete read of the file rather than a partial one. Anyone checking a specific address can find its own recorded numbers on that lot's page, distinct from the citywide shares here, while the applicable floor-area and height limits sit, cited, in the tables above.
