M1-3/R7X Zoning District — New York City

This designation's recorded stock skews newer than any other profiled in this batch: 42% of buildings on its roughly 42 tax lots have gone up since 2000, even though the median construction year, 1963, still lands inside the 1945-1975 postwar boom window. That boom itself accounts for only 19% of the stock, and 39% predates 1940 — meaning the file records three eras here too, but weighted toward the newest rather than the oldest, the reverse of the pattern several other designations in this batch show. Height follows an uneven pattern of its own: buildings run to a median of just 3 stories, yet 37% are recorded above 6 floors, a split that points to short older structures standing alongside a real cluster of taller, newer ones rather than a single consistent building form running across the whole footprint.

Garage buildings lead the recorded classes at 24%, with elevator apartment buildings at 14% and hotel buildings at 12% — a mix that pairs vehicle and lodging uses with the taller residential stock the height figures suggest, rather than the walk-up or rowhouse pattern more common among designations elsewhere in this batch. Land use runs commercial-and-office at 24%, mixed residential-and-commercial at 19%, and parking at 12%, a spread that keeps no single use dominant. Only 31% of lots are coded residential, yet the file counts 1,681 homes across the designation — a large unit total for that residential share, consistent with the taller buildings among the recorded stock carrying most of the housing rather than the low-rise majority of lots doing so.

Lots run larger here than in some paired designations in this batch, a median of 6,840 square feet with the 90th percentile reaching 25,910 square feet — room enough for the taller, newer construction the age figures describe. None of these lots, 0%, sit inside the mapped federal flood zone, and none, 0%, carry historic-district status on record, leaving no recorded overlay from either the flood map or landmark review on this designation's footprint.

Development room stays broad: 74% of lots record floor area below their allowance, with a median residual of 3.9 FAR, among the wider recorded gaps in this batch. Beyond these citywide shares, each of the roughly 42 lots carries its own figures on its own page; the governing floor-area and height rules for this designation, with their citations, sit in the tables above rather than in this summary.
