R5D Zoning District — New York City

Most designations in this batch are led decisively by one building class; this one is not. Walk-up apartment buildings lead the recorded classes at only 30%, with mixed residential-and-commercial buildings close behind at 20% and two-family homes at 19% — a three-way spread rather than a single dominant category. Land use tells the same story: walk-up use covers 30% of these roughly 4,700 tax lots, one- and two-family use 27%, and mixed residential-and-commercial use 24%, three nearly even shares rather than one clear majority. That double pattern — no dominant building class and no dominant land use — is unusual among the designations profiled in this batch, most of which show one category well ahead of the rest. No other designation profiled alongside this one splits its recorded stock this evenly across three separate categories at once.

That mixed composition shows up in the residential share too: 81% of lots are coded residential, a lower share than most designations in this batch record, with the file counting 22,964 homes. Construction here spans a real range: the median year is 1931, with 60% of buildings on record predating 1940. The 1945-1975 postwar boom left a real mark at 22% of the stock, and 10% of buildings have gone up since 2000 — a meaningfully more recent tail than the oldest, most uniform designations in this batch show. Taken together, the age record here is more spread across eras than concentrated in one, echoing the same three-way balance that shows up in the building-class and land-use figures above.

Height stays low despite the mixed-use composition: a median of 2 stories, with 0% of recorded buildings rising above 6 floors. Lots run a bit larger than the tightest designations in this batch, at a median of 2,308 square feet with the largest recorded parcels reaching 6,623 square feet. The federal flood map places 1% of these lots inside the mapped Special Flood Hazard Area, and none of the recorded lots, 0%, carry historic-district status.

On the development side, 80% of lots record floor area below their allowance, with a median residual of 0.8 FAR — a real gap, though on lots already carrying more mixed and commercial use than most of this batch. That figure describes what is recorded as unbuilt capacity on each lot today, not what will eventually be built there. Each of the roughly 4,700 lots carrying this designation has its own page with these figures broken out individually, and the floor-area and height rules that govern it, with their citations, sit in the tables above.
