M1-2A Zoning District — New York City

This designation is mapped across roughly 320 tax lots, a substantial footprint, but three of the recorded stock's most basic measures are simply absent from the file: there is no reliable year-built coverage, no floor coverage, and no development-capacity or headroom figure for any of these lots. That is an honest gap in the record rather than a claim that these lots lack buildings or floor area — it means the underlying data this file draws on does not reliably cover age, height, or capacity here. For a footprint this large, that is a meaningful absence, and it shapes what can and cannot be said about the stock below.

What the file does carry describes an industrial and partly vacant footprint. Garages lead the recorded building classes at 25%, followed by warehouses at 17% and vacant-land classifications at 16% — a stock of working and empty ground rather than finished buildings. By land use, industrial-and-manufacturing use covers 25% of lots, transportation-and-utility use another 22%, and vacant land a further 18%, three categories that together describe most of the mapped footprint. Working, transportation, and vacant uses dominating the land-use file this thoroughly, alongside garages and warehouses leading the building classes, describes a footprint built for industry and storage rather than for people to live in.

Only 13% of these lots are coded residential, and together they record 398 homes across the full 320-lot footprint — a small number of housing units relative to the scale of the mapped area. Lot sizes vary widely: a median of 3,624 square feet against a 90th percentile of 30,979 square feet, meaning most parcels are modest but a meaningful share run far larger, consistent with the working and industrial uses described above. A low residential share next to a wide lot-size spread is consistent with a footprint that mixes small working parcels with a handful of much larger industrial or vacant sites.

0% of these lots sit inside the mapped federal flood zone on record, and 0% carry historic-district status — an absence on both counts across all 320 parcels. Where the file is silent, as with age, height, and development capacity here, that silence is itself worth noting rather than filled in with an estimate. Between the industrial land use, the low residential share, and the gaps in age and capacity coverage, this designation's 320 lots read as a working footprint the file has only partly measured. The floor-area and use rules that actually govern this designation, where they apply, are set out, with citations, in the tables above.
