R7D Zoning District — New York City

The recorded land use here tilts toward mixed use more than most designations profiled in this file. Mixed residential-and-commercial parcels account for 46% of lots, nearly half the footprint, with commercial-and-office use adding another 11% and multi-family walk-up use 11% more — a land-use ledger that reads closer to a corridor than a purely residential block. Only 66% of lots are coded residential overall, one of the lower shares in this batch, describing a fabric built as much for storefronts and offices as for housing, and leaving a meaningful share of the footprint recorded for uses other than living space.

Construction here is prewar at its base but thin through the middle of the century: 77% of recorded buildings predate 1940, while just 3% date from the 1945-1975 postwar boom, one of the quietest boom-era shares in the file. Building has picked back up more recently — 16% of the stock has gone up since 2000, more than five times the boom-era share, on a median construction year of 1920 — suggesting a fabric that sat largely untouched through the middle of the twentieth century before newer construction started filling in again. Mixed residential-commercial buildings lead the recorded classes at 25%, with walk-up apartment buildings at 20%, a pairing that tracks the mixed-use land pattern described above.

Lots run to a median of 2,500 square feet, with the 90th percentile reaching 12,000 square feet — a moderate spread for a designation this size, roughly 910 tax lots citywide. Height stays low, at a median of 3 stories, though 9% of recorded buildings rise above 6 floors, a notable share given the otherwise low-rise profile and one of the more visible exceptions to the designation's general scale. The tax-lot records count 12,224 homes across the roughly 910 lots carrying this designation, a modest total that matches the mixed-use, lower-residential character described above.

Room to build shows up widely on paper: 89% of lots record floor area below their allowance, with a median gap of 2.7 FAR — among the broader recorded gaps in this batch, and a sizable share given how much of the footprint is already coded mixed use rather than purely residential. None of these lots, 0%, carry historic-district status on record, while 5% sit inside the mapped federal flood zone, a modest share of the footprint. Each lot's own recorded specifics, along with the rules that actually govern it, are detailed on its individual page and in the tables above, separate from the stock-wide picture described here.
