M1-6 Zoning District — New York City

At a median of 9 stories, the recorded stock on the roughly 110 tax lots carrying this designation runs taller than most of its family, with 58% of buildings rising above 6 floors — among the higher recorded shares in this comparison set. The age record sits in the middle of the pack: a median construction year of 1924, with 75% of buildings predating 1940, 3% falling inside the 1945-to-1975 postwar boom, and 18% built since 2000, a real recent layer added onto an older base and one of the larger recent-construction shares recorded among these pairings. Neither the oldest nor the newest profile in this family, this designation instead reads as a steady blend of both eras rather than a break between them.

The recorded building classes and land use both lean toward commerce rather than housing. Office buildings lead the class file at 32%, condominiums follow at 16%, and walk-up apartment buildings add 11%. By land use, commercial-and-office use covers 46% of these lots, well ahead of mixed residential-and-commercial use at 15% and multi-family walk-up use at 10% — the largest single land-use category in this pairing by a wide margin, and a clearer commercial lean than several comparable designations show, with office space and commercial use reinforcing each other across both measures.

Just 32% of these roughly 110 lots are coded residential, a minority share, though the file still counts 2,575 homes on them — a real recorded population concentrated on a smaller share of the footprint rather than spread across most of it. Lot sizes vary widely, a median of 7,500 square feet with a 90th percentile reaching 35,532 square feet, scale consistent with the office buildings leading the class file and with larger commercial sites generally, wide enough to support both the taller towers and the smaller mixed parcels recorded here.

A modest 9% of these lots sit inside the mapped federal flood zone, and just 2% carry historic-district status on record — both comparatively light overlays for a designation this size, leaving most of the footprint outside either regulatory layer. The file carries no reliable development-capacity coverage here, so no headroom or residual-FAR figure can be cited for these lots — an absence in the record rather than a claim about what could still be built on this footprint. The rules tables above set out the governing floor-area and height numbers with their citations for any specific parcel.
