M1-5/R7-3 Zoning District — New York City

Most of the designations profiled in this batch lean clearly toward one construction era or another. This one does not: 43% of its recorded buildings predate 1940, while 42% have gone up since 2000 — a near-even split between the oldest and newest categories this file tracks, with almost nothing in between. The median construction year, 1941, sits right at the edge of that prewar boundary, and only 5% of the stock falls inside the 1945-1975 postwar boom that separates the two larger shares. Read plainly, this is a designation where old and new construction sit side by side on record, rather than one having gradually given way to the other.

That recency shows up in height too: a median of 4 stories, with 42% of recorded buildings rising above 6 floors — among the taller profiles in this comparison set, and consistent with the share of genuinely new construction on file. Across the roughly 120 tax lots that carry this designation, that combination of age split and height marks it apart from the older, flatter stock recorded on some of the other designations in this batch.

By recorded class, condominiums lead at 20%, elevator apartment buildings follow at 14%, and factory and industrial buildings add 9%. Land use runs 38% mixed residential-and-commercial, 15% industrial and manufacturing, and 14% commercial-and-office. 59% of lots are recorded as residential, and the file counts 4,437 homes on them — a substantial population for a designation of this size.

72% of these lots record floor area below their allowance, with a median residual of 2.3 FAR. Lots run to a median of 4,997 square feet, with the largest recorded parcels reaching 24,800 square feet. Only 3% of lots sit inside the mapped federal flood zone, and none, 0%, carry historic-district status on record. The FAR and height limits that actually apply here are catalogued, with their citations, in the tables above, distinct from the recorded-stock figures on this page.

Set alongside the almost-even age split described above, the height and headroom figures round out a designation built for real density on a comparatively small footprint. A median residual of 2.3 FAR on the 72% of lots that record any headroom suggests that recorded capacity sits mostly on taller, already-substantial buildings rather than on vacant or minimally built ones, consistent with a median height of 4 stories. Lot size adds to that picture: a median of 4,997 square feet reaching 24,800 square feet at the 90th percentile gives this designation's roughly 120 tax lots more room to work with than several of the more tightly platted designations profiled elsewhere in this batch.
