M1-2/R8A Zoning District — New York City

Fifteen tax lots carry this designation, and the recorded stock on them is old: a median construction year of 1908, with 71% of recorded buildings predating 1940. Only 29% date from 2000 or later, and 0% fall within the 1945-1975 postwar boom — a stock that was substantially built out before the mid-twentieth century and has since been added to only at the edges. A construction record split almost entirely between a deep prewar layer and a smaller recent one, with nothing recorded in between, describes a designation that has seen two distinct waves of building activity a century apart and little else.

That age pairs with a heavy landmark overlap: 53% of these lots carry historic-district status on record, meaning more than half sit under some form of preservation review layered on top of whatever this designation itself permits. The recorded building classes lean toward condominiums, 40% of tracked classes, with elevator apartment buildings at 20% and walk-up apartment buildings at 13%. By land use, mixed residential-and-commercial parcels hold 60% of the lots, multi-family walk-up use another 13%, and commercial-and-office use a further 13%. The mix of condominium and elevator-apartment classes suggests conversion and rebuilding layered onto an old base, which the historic-district share and the prewar year-built figures both help explain.

Height on record runs to a median of 9 stories, with 62% of recorded buildings rising above 6 floors — a mid-rise pattern consistent with the elevator-building share above. 80% of the lots are coded residential, and together they record 1,114 homes across the fifteen parcels. Lot sizes vary more here than at some of the smaller designations: a median of 10,337 square feet against a 90th percentile of 31,200 square feet, a wider spread that points to some genuinely large assembled parcels among the smaller, older ones. That spread in lot size gives this designation more internal variety across its fifteen parcels than a uniform footprint would show.

The development ledger shows headroom on more than half the footprint: 53% of lots record floor area below their allowance, with a median residual of 0.3 FAR — modest room, on parcels that in many cases also carry the historic-district review noted above. 27% of these lots sit inside the mapped federal flood zone on record, a statement about the regulatory boundary rather than a record of actual flooding. Between the age of the stock, the historic-district coverage, and the recorded flood exposure, this designation's fifteen lots carry more layered record-keeping than their modest size might suggest. Each lot's own page carries its recorded specifics; the rules tables above carry the governing floor-area and height numbers with their citations.
