M1-4/R8A Zoning District — New York City

A landmark overlay this large is uncommon among the designations in this file: 40% of the roughly 55 tax lots carrying this designation sit inside a designated historic district, layered on top of whatever zoning applies to each. The building stock beneath that overlay runs taller than most low-rise designations too — a median of 5 stories, with 39% of recorded buildings rising above 6 floors. A historic-district share this high, paired with height this pronounced, describes a designation where landmark review and taller recorded construction sit on the same ground, rather than the low-rise pattern historic overlays more often accompany elsewhere in this file.

The recorded stock is split nearly evenly between two construction eras: 43% of buildings predate 1940, and 45% have gone up since 2000, with only 6% from the 1945-1975 postwar boom bridging them. The median construction year, 1980, sits well inside that gap rather than describing either wave directly — a reminder that a median can land between two clustered peaks rather than at the center of either one. Whatever construction happened in the decades between the postwar boom and the recent wave appears comparatively light on this ground, sandwiched between an older layer and a newer one that together account for almost all of the recorded stock.

By land use, mixed residential-and-commercial parcels lead at 35% of lots, with commercial-and-office use and industrial use each recording 13%. Building classes on record lead with elevator apartment buildings at 16% and condominiums at 15%, alongside a further class at 11%. Overall, 52% of lots are coded residential, and the file counts 3,506 recorded homes across this designation's footprint — a substantial residential base for a stock this tall and this historically layered, with condominium ownership recorded alongside more traditional rental apartment buildings.

On a median lot of 11,958 square feet, reaching as high as 43,600 square feet at the 90th percentile, 5% of lots sit inside the mapped federal flood zone — the boundary drawn on the federal map, not a history of which lots have flooded. The development ledger shows 78% of lots recording floor area below their allowance, at a median gap of 2.2 FAR, even with the historic-district review layered over much of the designation — recorded headroom and landmark status coexisting on the same lots rather than one crowding out the other. The governing floor-area and height rules, and any landmark considerations, are set out, with citations, in the tables above.
