M1-4 Zoning District — New York City

This designation is mapped across roughly 920 tax lots citywide, the largest footprint of any designation profiled in this batch by a wide margin — most others here run to dozens or a few hundred lots. That scale comes with real gaps in the file: no reliable year-built, floor-height, or development-capacity coverage exists for these lots, more absence across more stat families than any other designation in this batch carries. What the file does record still runs deep on composition, flood status, and lot size for each of the 920 lots individually, even where three whole stat families are unrecorded at the citywide level.

The recorded building classes point squarely toward industrial and service use: garage buildings lead at 24%, warehouse buildings follow at 18%, and factory-and-industrial buildings add 14% — three classes built for storage, shipping, and production rather than living space. Land use bears this out directly: industrial-and-manufacturing use covers 34% of these lots, parking facilities another 20%, and commercial-and-office use 11%. It is the most manufacturing-coded land-use mix of any designation in this batch, a composition that tracks the designation's role as a working, rather than residential, base.

Only 11% of lots are coded residential — one of the lowest shares in this batch — yet the file still counts 8,313 recorded homes across the designation, by far the largest unit total here despite that small residential share. That combination describes a designation where housing is a minority use by lot count but a major one in aggregate, likely concentrated on a limited number of larger residential parcels within a mostly industrial footprint, rather than spread evenly across the 920 lots this designation covers.

Lots run a median of 5,187 square feet, with the 90th percentile reaching 41,188 square feet — a wide spread consistent with small service parcels sitting alongside large industrial assemblages under the same designation, rather than a uniform lot size across the whole footprint. Flood exposure touches 7% of these lots, a modest share, and none, 0%, carry historic-district status on record.

With age, height, and development capacity unrecorded at this scale, lot size, flood status, and building and land-use composition carry most of the descriptive weight for this designation. Recorded specifics for each of these roughly 920 lots sit on that lot's own page; the floor-area and height rules actually governing the designation, citations included, are above in the tables rather than restated in this summary.
