M1-2A/R6A Zoning District — New York City

Across the 150 tax lots carrying this designation, 93% record floor area below their allowance, and the median residual sits at 2 FAR — a wide recorded gap, and notable because it sits on a stock that is not tall to begin with. The median height on these lots is just 2 stories, and only 2% of recorded buildings rise above 6 floors. Wide recorded headroom next to a low-rise stock like this describes buildings that simply were not built up to whatever capacity their lots record, not a prediction that they will be. Across 150 parcels, a 93% headroom share is close to universal, meaning the pattern holds for nearly the entire footprint rather than a handful of outlier lots.

That low-rise stock is also an old one: a median construction year of 1930, with 74% of recorded buildings predating 1940. The 1945-1975 postwar boom contributed 12% of the stock, about the same share, 12%, that has been built since 2000 — meaning the last quarter-century has added about as much as the three postwar decades did, on top of a base that was already three-quarters built out before 1940. An old, low base with two smaller and roughly equal waves of later construction on top of it is the pattern these 150 lots' year-built records describe.

The recorded building classes lean toward garages, 22% of tracked classes, with walk-up apartment buildings at 21% and two-family homes at 10% — a working, low-rise mix rather than a residential-only pattern. By land use, multi-family walk-up use covers 22% of lots, industrial-and-manufacturing use 19%, and parking facilities 15%, three categories that together track closely with the building classes above. 43% of the lots are coded residential, and together they record 808 homes. A residential share just under half, next to a building-class file led by garages, describes a footprint that mixes housing with working and parking uses rather than one dominated by either.

Lot sizes run modest: a median of 2,750 square feet, with the largest recorded parcels reaching 16,000 square feet. 13% of these lots sit inside the mapped federal flood zone on record, and 0% carry historic-district status. Between the wide recorded headroom, the low-rise and prewar-heavy stock, and the modest lot sizes, this designation's 150 parcels describe an older, low footprint with substantial recorded room above what is currently built. Each lot's own page carries its individually recorded floor area and building details; the rules tables above carry the governing floor-area and height numbers with their citations.
