R7X Zoning District — New York City

The recorded stock under this designation sits low even by the standards of this file: a median height of 2.5 stories, with only 13% of buildings rising above 6 floors, keeping the skyline consistently low across the roughly 800 tax lots that carry this designation. The median construction year is 1931, and 63% of recorded buildings predate 1940 — a smaller prewar majority than several designations in this batch, with 12% dating from the 1945-1975 boom, a slightly larger boom-era share than many low-rise designations show. Recent building has been comparatively active: 18% of the stock has gone up since 2000, the fastest recent-construction share among the ten designations covered here, adding meaningfully to a stock that is otherwise older and lower than most.

Mixed residential-and-commercial use leads the land-use mix at 31%, followed by one- and two-family use at 17% and multi-family walk-up at 13% — a spread across several use types rather than one dominant category. The building classes echo that spread without any single type dominating: walk-up apartment buildings lead narrowly at 16%, with mixed residential-commercial buildings at 14% close behind, and no other class approaching either figure. Residential use covers 69% of lots, and the tax-lot records count 15,393 homes across the roughly 800 lots carrying this designation, a moderate housing total for a footprint mapped across relatively few parcels.

Lots run to a median of 2,836 square feet, with the 90th percentile reaching 16,000 square feet, room enough at the upper end for larger low-rise buildings even where the typical parcel stays modest. The federal flood map places 13% of these lots inside the mapped Special Flood Hazard Area, a higher share than most designations in this batch — a statement about the regulatory boundary, not a record of which lots have taken on water, and worth checking parcel by parcel for anyone with a specific lot in mind. None of the lots, 0%, carry historic-district status on record, leaving the entire footprint outside landmark review.

Recorded capacity runs broad here: 91% of lots show floor area below their allowance, with a median gap of 3.7 FAR, among the wider recorded gaps in this file — consistent with a stock built low relative to what stands on paper, and with construction that, as noted above, has already been catching up faster than most designations in this batch. What governs any one of these lots — floor area, height, every citation — sits in the tables above rather than in this description, which covers only what the records show already stands.
