R6D Zoning District — New York City

Two figures set this small designation apart from the rest of this batch. Fully 99% of lots record floor area below their allowance — the widest recorded headroom of any designation profiled here — and 15% of recorded buildings date from 2000 or later, also the highest share in this batch. Both are recorded facts about the built stock, not a claim about what will happen next. Roughly 170 tax lots carry this designation citywide, a small count by comparison with the larger designations in this batch, yet the two standout figures above make it one of the more distinctive entries in the set — a designation this small rarely posts numbers this extreme on two separate measures at once.

Two-family homes lead the recorded building classes at 30%, with mixed residential-and-commercial buildings and one-family homes each recorded at 20%. By land use, one- and two-family parcels cover 50% of these lots, mixed residential-and-commercial use adds 22%, and vacant land a further 10% — a meaningfully higher vacant-land share than most designations in this batch carry. That mix, weighted toward two-family and one- and two-family parcels with a real vacant-land minority, describes a small but conventionally residential footprint rather than a commercial one.

Construction is mostly old despite that high recent-decades share: 73% of buildings on record predate 1940, and the median construction year is 1930, with only 6% dating from the 1945-1975 postwar boom. Buildings run to a median of 2 stories, with 0% rising above 6 floors. Overall, 75% of lots are coded residential, and the file counts 324 homes — a small total consistent with the designation's small footprint. That small homes count, set against the batch-leading since-2000 share above, suggests the recent construction here has added to a genuinely small base rather than a large one. None of that recent construction has yet pushed the designation's overall age profile toward the newer end of this batch — the stock here is still mostly old, just with a meaningfully larger recent layer on top.

Lots run a median of 2,700 square feet, with the largest recorded parcels reaching 5,750 square feet. None of these lots, 0%, sit inside the mapped federal flood zone or carry historic-district status on record. The median residual behind that 99% headroom figure is 1.8 FAR. Each of the roughly 170 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.
