M1-5/R8A Zoning District — New York City

Across the roughly 31 tax lots carrying this designation, the construction record splits into two eras with almost nothing recorded between them: 60% of buildings predate 1940, 40% have gone up since 2000, and the 1945-to-1975 postwar boom claims 0% of the stock on file — three decades that left essentially no trace here. The median construction year is 1931, sitting inside the older half of that split, which means the 40% built since 2000 is doing real work to pull the overall file toward the present. Few designations in this comparison carry so little from the boom years alongside so much built in recent decades.

The recorded building classes favor height and ownership type over any single dominant use: elevator apartment buildings lead at 19%, warehouses follow at 13%, and condominiums add another 13%, a combination that pairs multifamily housing with working space rather than settling on one pattern. Land use tells a matching story — mixed residential-and-commercial parcels and industrial-and-manufacturing parcels tie at the top, each covering 22% of these lots, with multi-family elevator use recording 15%. Just 41% of lots are coded residential even so, and the file counts 2,421 homes on them, concentrated on a minority of the roughly 31 parcels rather than spread evenly across all of them.

Height on record runs to a median of 5 stories, with 38% of buildings rising above 6 floors, a meaningful share for a file this size. The ground underneath runs larger than many comparable designations — a median lot of 15,000 square feet, with a 90th percentile reaching 41,289 square feet — scale consistent with the elevator buildings and warehouses leading the class file above. Flood exposure is real but not dominant: 35% of these lots sit inside the mapped federal Special Flood Hazard Area, a statement about the regulatory boundary drawn on the federal map rather than a ledger of which parcels have taken on water. None of the lots, 0%, carry historic-district status on record.

The development file shows broad recorded headroom: 77% of these lots record floor area below their allowance, with a median gap of 3 FAR — even as the recent 40%-since-2000 share shows some of that capacity already being drawn down in practice. Each lot's own page carries its specific recorded figures, and the rules tables above set out the governing floor-area and height limits with their citations for anyone checking a particular parcel.
