M1-1 Zoning District — New York City

At roughly 12,000 tax lots, this is the largest designation profiled in this batch, and its recorded stock reads as classically industrial. Warehouses and garages each lead the recorded building classes at 17%, with vacant land close behind at 10% — a mix of active industrial use and undeveloped ground rather than any residential pattern on its face. By land use, industrial-and-manufacturing use covers 28% of lots, well ahead of one- and two-family use at 15% and transportation-and-utility use at 11%, a spread that puts genuine distance between the leading category and everything else recorded. A footprint this large, at roughly 12,000 lots, means the shares above describe a genuinely citywide pattern rather than a handful of parcels.

The construction record centers on the prewar era: a median year built of 1931, with 54% of recorded buildings predating 1940. The 1945-to-1975 postwar boom left a real mark too, at 25% of the stock — a larger boom-era share than several other designations in this batch carry — while 11% of buildings on record date from 2000 or later, layered on top of that older, boom-era base rather than replacing meaningful portions of it. Between the 54% prewar share and the 25% boom-era share, the great majority of this designation's recorded stock predates 1975 outright.

Only 28% of these roughly 12,000 lots are coded residential, yet the file counts 24,569 homes on them — one of the larger recorded unit totals in this batch, concentrated on a clear minority of the designation's parcels rather than spread across it, a records detail worth flagging rather than smoothing over. Lots run moderate in size, with a median of 4,800 square feet and the largest recorded parcels reaching 36,100 square feet. The recorded stock stays low across the board: a median of 2 stories, with 0% of buildings rising above 6 floors, a flat industrial profile rather than a mixed one.

Flood mapping places 9% of these lots inside the mapped federal Special Flood Hazard Area, a minority reading but a real one across a footprint this large; landmark protection is entirely absent from the file — 0% of lots — which fits a designation built almost entirely for industrial and utility use rather than the landmarked residential fabric found elsewhere in this file.

One family of statistics is honestly missing: residential floor-area capacity has too little coverage across these lots to summarize, so this page offers no headroom or residual figure — the records simply do not support one at this designation's scale, and quoting a number anyway would be invention. Everything else — class, use, vintage, height, flood coding — is tracked lot by lot across the roughly 12,000 parcels. For what may lawfully be built, the governing rules render in the cited tables higher on this page.
