R6-1 Zoning District — New York City

Few designations in this batch carry as little residential character as this one. Roughly 90 tax lots carry it citywide — among the smallest counts recorded in this batch — and only 33% of those lots are coded residential, with the file counting just 184 homes. The leading recorded building classes, at 26% and 17% of the mix, fall outside the residential and vacant-land categories this batch decodes; vacant-land classifications account for a further 12%. By land use, commercial-and-office parcels lead at 20%, mixed residential-and-commercial use follows at 15%, and one- and two-family use adds 13% — a spread weighted toward commercial and mixed use rather than housing, unlike most of the other designations profiled in this batch. A designation with this little residential character and this few recorded lots stands apart from the more conventionally residential designations that make up most of this batch.

Construction age sits right at the edge of this batch's prewar marker: the median year built is 1940, and 49% of recorded buildings predate that year — just under half. The 1945-1975 postwar boom left a real mark here too, at 31% of the stock, a notably larger boom-era share than most designations in this batch carry, while 7% of buildings have gone up since 2000. That combination — a median year sitting exactly on the prewar cutoff, with a meaningful boom-era layer on top — sets this designation's age profile apart from the more uniformly old or uniformly recent stocks elsewhere in this batch.

Buildings here run low: a median of 1 story, with 0% of recorded buildings rising above 6 floors. Lots run larger than the tightest designations in this batch, at a median of 3,816 square feet with the largest recorded parcels reaching 12,800 square feet — room consistent with the commercial and mixed uses that lead the land-use mix above. That combination of low height and larger-than-typical lots reads as a footprint built for commercial or mixed use rather than for housing.

None of these lots, 0%, sit inside the mapped federal flood zone or carry historic-district status on record. The development ledger shows one of the widest recorded headroom shares of any designation in this batch: 98% of lots record floor area below their allowance, with a median residual of 2.3 FAR. Together, the age, height, and development figures describe a small, mostly non-residential corner of the record rather than a housing-focused designation. Each of the roughly 90 lots carrying this designation has its own page with these figures broken out individually; the floor-area and height rules that govern it, with their citations, sit in the tables above.
