M1-5/R9 Zoning District — New York City

Few designations in this family read as recent as this one. Across the roughly 52 tax lots carrying it, the median construction year is 2012, and 60% of recorded buildings date from 2000 or later — a stock built overwhelmingly within the current century. The 1945-to-1975 postwar boom shows up only lightly, at 4%, and just 33% of the stock predates 1940, meaning recency, not age, is what defines this file. Height matches that recency closely: a median of 13 stories, with 70% of recorded buildings rising above 6 floors, among the taller profiles in this comparison set.

Elevator apartment buildings lead the recorded classes decisively at 43%, with condominiums following at 18% and office buildings at 12% — a vertical, multifamily-housing pattern rather than a low-rise or industrial one. Land use backs that reading: mixed residential-and-commercial parcels cover 55% of these lots, commercial-and-office parcels another 16%, and multi-family elevator parcels 12%, a land-use file that tracks the building-class order above it closely rather than diverging from it. Two-thirds of the file, 67%, is coded residential, and the file counts 6,027 homes on the roughly 52 lots — a substantial recorded population for a footprint this size, consistent with the tall, elevator-building stock leading the class file above and reflecting just how much housing a modern tower can concentrate onto a small number of parcels.

The lot fabric underneath runs a wide range: a median of 7,996 square feet, with a 90th percentile reaching 41,628 square feet, ground large enough at its upper end to carry the elevator towers the class file shows and modest enough at its median to still register as an ordinary city block. None of these lots, 0%, sit inside the mapped federal Special Flood Hazard Area, and none, 0%, carry historic-district status on record — this is a stock built recently enough, and on ground positioned such, that neither of those overlays touches it at all.

The development file reads thin-but-broad rather than deep: 42% of lots record some floor area below their allowance, yet the median residual sits at 0 FAR, meaning at least half of the roughly 52 lots are already built to their recorded capacity or beyond it. That combination — real recency, real height, and little remaining recorded headroom — reads as a stock built close to what its ground can currently carry, in contrast to older designations elsewhere in this file that still show wide recorded gaps. Each lot's own page carries its specific figures, and the rules tables above set out the governing numbers with their citations.
