M1-1D Zoning District — New York City

Across 370 tax lots citywide, this designation's recorded stock reads as a residential neighborhood built up against industrial ground. The median construction year is 1920, and 68% of buildings predate 1940 — a solid prewar majority, though not as total as some of the smaller, older designations elsewhere in this file. The 1945-1975 postwar boom added a further 19% of the stock, and 7% of buildings on record date from 2000 or later, a modest but real trickle of recent construction layered onto an otherwise old base. Taken together, these shares describe a stock that finished most of its growth well before the middle of the twentieth century and has only lightly been added to since.

Two-family homes lead the recorded building classes at 29%, with walk-up apartment buildings and warehouses tied at 14% each. Land use follows a similar residential lean: one- and two-family use covers 43% of the 370 lots, well ahead of industrial use at 23% and multi-family walk-up use at 14%. Put together, these shares put 64% of the 370 lots in the residential column, with 733 homes on file — a working residential fabric that shares its footprint with recorded industrial ground rather than standing entirely apart from it, the way some purely residential designations in this file do.

Lots run to a median of 2,500 square feet, with the largest recorded parcels reaching 10,000 square feet — enough spread to hold both the small rowhouse-scale lots and a handful of larger, industrial-adjacent parcels within the same designation. Heights stay low throughout: a median of 2 stories, with 0% of buildings rising above 6 floors, consistent with the two-family and walk-up pattern the building classes describe. Recorded floor area sits beneath the citywide allowance on 81% of these 370 lots, with a typical gap of 0.6 FAR — broad in reach across the designation, if modest in size on any one parcel.

By the federal flood map, none of these 370 lots, 0%, fall inside the mapped hazard zone, and none, 0%, are recorded as inside a historic district — an absence consistent with a stock that sits inland of the waterfront-adjacent designations profiled elsewhere in this batch and outside any landmark boundary. The 370 lots each carry their own recorded figures beyond the citywide shares quoted here, and the specific floor-area and height limits attached to the designation, citations included, sit in the tables above for anyone checking a particular parcel against the rest of the file.
