M1-5/R9-1 Zoning District — New York City

Only 13 tax lots carry this designation citywide, one of the smaller footprints among its family, and its file is missing two of the usual stat families entirely: no reliable year-built coverage and no reliable floor-height coverage are recorded for these lots. Rather than estimate around that gap, it is worth stating plainly — construction era and story count simply are not on file here, and what follows covers only what the records do carry rather than filling in around the absence with a guess either way. A footprint this small also means every individual lot's file carries real weight in the percentages that follow, unlike a larger designation where any one parcel barely moves the recorded share.

What the records do carry is a striking development figure: 85% of these 13 lots record floor area below their allowance, with a median residual of 8 FAR — among the widest recorded gaps of any designation in this family. On a footprint this small, that figure describes a real pattern across most of the parcels rather than a handful of outliers pulling an average. Garages and condominiums are tied atop the recorded building classes at 23% each, with warehouses adding 15% — a working-and-housing mix rather than a single dominant type, and one that pairs storage and service uses with real multifamily ownership on the same small footprint.

By land use, mixed residential-and-commercial use leads at 33%, parking covers a real 25% of these lots, and commercial-and-office use adds 17% — a spread that echoes the mixed building-class file rather than contradicting it, with parking recording a notably larger share here than in most comparably sized designations. Only 33% of the 13 lots are coded residential, and the file counts 613 homes on them, a modest population consistent with a footprint this size. Lot sizes run to a median of 10,000 square feet, with the largest recorded parcels reaching 19,044 square feet, a spread wide enough that the larger lots likely carry a disproportionate share of the recorded units.

An 8% share of these lots also carries historic-district status on record, a real if modest overlap layered onto a small footprint, while none of the 13 lots, 0%, sit inside the mapped federal flood zone — an absence from the flood map that stands in contrast to how widely the development gap and the parking use extend across the same parcels. Each lot's own page carries what building-class, land-use, and development figures are on file for it individually, and the rules tables above set out the governing floor-area numbers with their citations for anyone checking a specific parcel.
