M1-1/R7D Zoning District — New York City
M1-1/R7D is a zoning district on New York City's zoning map.
M1-1/R7D is a zoning district on New York City's zoning map. It allows industrial and commercial uses; new residences are generally excluded. 22 tax lots citywide carry M1-1/R7D as their primary zoning designation.
This designation maps to roughly 22 tax lots citywide, and its development file shows the widest recorded gap in this batch: 86% of lots carry floor area below their allowance, with a median residual of 4.3 FAR. Garages lead the recorded building classes at 32%, parking use covers 27% of lots, and 41% of lots are coded residential, holding 298 homes. None sit inside the mapped flood zone, and the records carry no reliable year-built or floor-height coverage.
What actually stands in this district
Among the designations profiled in this batch, this one — roughly 22 tax lots — records the widest floor-area gap of the set: 86% of lots carry recorded floor area below their allowance, with a median residual of 4.3 FAR, a wider recorded margin than any of the other designations in this batch show. That reading describes the difference between what is built and what the file lists as allowed, not a claim about what happens to any given lot next, and it stands out even among a batch that includes several designations with real recorded headroom. A gap this wide, on a footprint this small, means the figure is driven by a genuinely large recorded margin rather than by scale.
Garages lead the recorded building classes at 32%, with elevator apartment buildings and vacant land classifications each at 23% — a mix that combines service space, taller residential construction, and a real share of undeveloped ground rather than any single use dominating outright. By land use, parking use covers 27% of these 22 lots, multi-family elevator use another 23%, and vacant land use 23%, a spread that leans on parking and vacancy more heavily than most designations in this batch. Parking, elevator housing, and vacant ground together account for most of what the file records here.
The records carry no reliable year-built or floor-height coverage for these lots — both families are unrecorded here, an honest gap rather than an estimate around it. What is on record still includes residential coding: 41% of these lots are coded residential, and the file counts 298 homes on them, alongside the parking and vacant-land uses that lead the mix above. That absence sits alongside real coverage on the other measures — building class, land use, lot size, flood status, and development capacity are all tracked for these same 22 parcels.
Lots run small, with a median of 2,415 square feet and the largest recorded parcels reaching 9,280 square feet. None of these lots, 0%, sit inside the mapped federal Special Flood Hazard Area — a statement about the current federal map, not a promise about water on any of these roughly 22 parcels — and none carry historic-district status on record.
Each lot's own recorded specifics sit on its own page, and the floor-area and height rules that govern this designation, with their citations, are set out in the tables above, for anyone checking a specific parcel against these citywide figures.
Bulk rules for M1-1/R7D

About manufacturing districts
Manufacturing districts allow industrial and many commercial uses; new residences are generally excluded. Manufacturing bulk is governed by § 43- of the NYC Zoning Resolution.
Contextual districts pair their floor-area ceilings with prescribed base and maximum building heights so new buildings mirror existing neighborhood form; non-contextual districts govern the envelope through more general height and setback rules, such as sky exposure planes. Commercial districts also allow residences under the rules of a residential-equivalent district, while manufacturing districts generally exclude new residences. Overlays and special purpose districts can modify any of this on a specific lot.
