R7-1 Zoning District — New York City

Lot sizes on this designation spread further than the median alone suggests. Half of these roughly 14,000 tax lots run below a median of 2,625 square feet, similar to the tighter designations elsewhere in this batch, but the largest recorded parcels reach 15,480 square feet — one of the widest recorded gaps between typical and large lots in this batch, describing a mix of small parcels and much larger assembled ground within the same designation. Few other designations profiled here show that same distance between their median and their upper range.

Walk-up apartment buildings lead the recorded classes at 35%, followed by two-family homes at 23% — but elevator apartment buildings register a real 14% share, notably more elevator presence than the two-family-led designations profiled alongside this one. By land use, multi-family walk-up use covers 33% of these lots, one- and two-family use 31%, and multi-family elevator use 12% — that elevator share appearing in both the class mix and the land-use mix together, a pairing that shows up less often than either figure alone might suggest.

Construction spans a real range: the median year is 1930, with 60% of buildings on record predating 1940 and 8% from the 1945-1975 postwar boom. A further 14% have gone up since 2000, among the higher recent-construction shares in this batch. Buildings run to a median of 3 stories, with 5% rising above 6 floors, and 86% of lots overall are coded residential, with 261,586 homes on record.

None of these lots, 0%, sit inside the mapped federal flood zone, and 5% carry historic-district status on record. On development, 78% of lots record floor area below their allowance, with a median residual of 2 FAR — one of the wider recorded gaps in this batch. Each lot's own page carries its recorded specifics individually, and the floor-area and height rules that govern this designation, with their citations, sit in the tables above.

The elevator-building presence described above is worth reading alongside the wide lot-size spread noted at the start of this profile: a designation running from a 2,625-square-foot median lot to parcels of 15,480 square feet has room across its roughly 14,000 lots for both the two-family and walk-up buildings that dominate the recorded classes and the smaller elevator-served share layered among them. The 78% of lots recording headroom, at a comparatively wide 2 FAR median residual, sits on that same varied lot fabric, meaning the recorded development room here is not confined to any single lot size or building type but spread across a genuinely mixed file.
