M1-1/R5 Zoning District — New York City

Among the smaller designations in this batch, this one — roughly 64 tax lots — carries one of the higher recorded flood exposures of the set: 89% of these lots sit inside the mapped federal Special Flood Hazard Area. That reading sits alongside a construction record showing real recent activity: 23% of buildings on record date from 2000 or later, a notably larger recent share than most comparably old designations in this file show, even though 70% of the stock still predates 1940 and the median construction year is 1931, a combination that reads as an old, flood-exposed footprint still being actively added to rather than one that has simply been left as it was.

One-family homes lead the recorded building classes at 19%, with vacant land and miscellaneous-use buildings each recorded at 16% — a mix that reads as a residential pocket with a real share of undeveloped or transitional ground alongside it. By land use, one- and two-family use covers 31% of lots, with mixed residential-and-commercial use and vacant land use each at 19%, a land-use file that echoes the residential-and-vacant split the building classes already show rather than contradicting it. No single category on either measure reaches even a third of these roughly 64 parcels.

The 1945-to-1975 postwar boom left only a small mark here, at 4% of the recorded stock — one of the thinner boom-era shares in this batch, well behind both the prewar share and the post-2000 share on record. 61% of these lots are coded residential, and the file counts 138 homes on them. Lots run small, with a median of 2,000 square feet and the largest recorded parcels reaching 10,000 square feet; buildings stay low, at a median of 2 stories with 0% above 6 floors, a flat height profile despite the real construction activity described above.

Development records show real recorded room: 73% of lots carry floor area below their allowance, with a median residual of 0.6 FAR — a real if modest margin on parcels this small. None of these lots, 0%, carry historic-district status on record, leaving this flood-exposed pocket without any landmark-review layer on file.

This designation's own recorded specifics sit on each lot's own page, and the floor-area and height rules that govern it, with their citations, are set out in the tables above, for anyone checking a particular parcel against these citywide shares rather than relying on the aggregate alone.
