M2-4 Zoning District — New York City

Of the designations in this batch that carry reliable year-built coverage, this one shows the most recent activity. The median construction year is 1940 — sitting exactly at the boundary that separates prewar construction from everything after it — and 18% of the recorded stock has been built since 2000, a notably larger recent share than most comparable designations in this file. Prewar construction still makes up 45% of the stock, and 16% falls inside the 1945-1975 postwar boom, so the file records activity across every era rather than concentrating in one, a spread that few designations elsewhere in this batch can show as evenly.

The recorded building classes lean toward vehicle and storage uses: garages lead at 28%, with warehouses and office buildings tied at 17% each. Land use runs 35% commercial and office, 19% industrial and manufacturing, and 15% mixed residential-and-commercial — a genuinely blended file rather than one dominated by a single use. Height stays mid-rise, a median of 4 stories, with 18% of recorded buildings rising above 6 floors, putting this designation between the low industrial sheds and the taller office corridors described elsewhere in this batch.

Only 18% of these roughly 81 lots are recorded as residential, yet the file counts 711 units in total — a meaningful housing presence layered onto what is largely a commercial-and-industrial file. Lots run to a median of 10,000 square feet, with the largest on record reaching 65,270 square feet. A recorded 2% of lots carry historic-district status, the largest such share among the designations covered in this batch, a small but genuine landmark presence inside a file otherwise built around commerce, industry, and vehicles.

The federal flood map places 15% of these lots inside the mapped Special Flood Hazard Area — a modest share, though not a negligible one. That is a statement about the regulatory flood boundary, not a record of which individual lots have taken on water. The file carries no reliable floor-area-capacity coverage for this designation, so no headroom figure can be reported here; the governing rules themselves, with their citations, sit in the tables above, alongside the recorded mix of uses and eras described in this file.
