M1-2/R6 Zoning District — New York City

Recent construction has left an outsized mark on the 240 tax lots carrying this designation: 29% of recorded buildings date from 2000 or later, well ahead of the 5% built during the 1945-1975 postwar boom. The median construction year is 1928, and 64% of the stock predates 1940 — a prewar majority, but one that recent decades have been actively building alongside rather than simply preserving. That combination — a prewar majority paired with the strongest recent-decades share any moderate-scale designation in this batch shows — sets this stock apart from designations where one era or the other dominates far more completely, with comparatively little construction recorded in between.

Walk-up apartment buildings lead the recorded building classes at 37%, with elevator apartment buildings and condominiums tied at 11% each. Land use runs mostly residential: multi-family walk-up use covers 35% of the 240 lots, mixed residential-and-commercial use another 25%, and multi-family elevator use 12%. In sum, 80% of the 240 lots are residential on record — one of the higher shares in this batch — holding 2,811 homes. That land-use mix, more varied than a single-use residential or industrial block, tracks closely with the building-class figures above it, and a housing count this size on only 240 lots points to a stock built mostly at multi-unit rather than single-family scale.

Heights run a little taller here than in some comparable designations: a median of 3 stories, with 12% of recorded buildings rising above 6 floors. Lots spread from a median of 2,500 square feet to a 90th-percentile figure of 11,647 square feet. Just over half of these 240 lots, 58%, record floor area under their allowance, with a narrower typical gap of 0.4 FAR than some of the older, lower-rise designations in this file show — consistent with a stock that has already used up more of its recorded capacity than the shorter, older designations profiled elsewhere in this batch.

The federal flood map places 12% of these 240 lots inside the mapped flood zone — a statement about the regulatory boundary rather than a record of actual flooding. None of the lots, 0%, carry historic-district status on record. Taken as a whole, the record describes a moderate-scale designation whose composition, height, and flood exposure have all shifted together as recent construction reshaped it. Each lot's recorded specifics sit on its own page, separate from the citywide figures above; the rules that actually set floor area and height for the designation are cited in the tables above.
