M2-3A Zoning District — New York City

This designation's recorded stock is industrial at its core but not exclusively so. Warehouses lead the recorded building classes at 37%, garages follow at 22%, and one-family homes still account for 11% — a real residential presence inside a file built mostly around manufacturing and storage uses. That mix is unusual: most heavily industrial designations in this comparison set show little to no one-family housing on record at all, which makes the 11% figure here worth noting rather than treating as background noise. Roughly 54 tax lots carry this designation citywide, a middling scale next to both the tiny and the very large files elsewhere in this batch.

Land use confirms the pattern: industrial and manufacturing use covers 45% of the roughly 54 lots, transportation and utility use another 16%, and one- and two-family use 12% — the same residential thread visible in the building-class mix above. Only 12% of these lots are recorded as residential overall, and the file counts 151 units in total, a modest number consistent with a scattering of houses inside a largely industrial footprint rather than a residential pocket of any real density. That combination of building-class and land-use figures lining up so closely suggests the residential thread here is genuinely woven into the industrial fabric rather than sitting apart from it.

The recorded stock is old and low across the board. The median construction year is 1931, with 60% of buildings predating 1940 and 28% falling inside the 1945-1975 postwar boom — a meaningfully larger boom-era share than several other designations in this file. Just 9% of the recorded stock has been built since 2000. Height stays low throughout: a median of 1 story, with only 2% of buildings rising above 6 floors, a profile consistent across both the industrial majority and the residential minority described above. Age and height together describe a file that has changed only modestly since its buildings first went up.

Lots run to a median of 10,000 square feet, with the largest on record reaching 47,000 square feet — mid-sized ground consistent with a mix of houses and small industrial buildings rather than large assembled holdings. None of the lots, 0%, sit inside the mapped federal flood zone, and none carry historic-district status on record. The file carries no reliable floor-area-capacity coverage for this designation, so no headroom figure is available here; the governing rules themselves are set out, with citations, in the tables above. What the file does carry — building class, land use, age, height, and lot size — is recorded down to the individual parcel.
