M3-1A
M-A Manufacturing District M3-1A (2.0 / 1.0 FAR)
New York City zoning district
M3-1A is defined as a M-A Manufacturing District M3-1A (2.0 / 1.0 FAR) in New York City.
In plain English
For heavy-industry business owners — the loud, polluting operations like fuel depots, recycling, or waste handling that other districts won't allow. M3-1A is low-density: up to twice the lot's area in floor space for industry, half that for commercial (FAR = floor-area ratio). The "A" adds contextual shape rules. Definitely no housing.

M3-1A regulates building height, lot size, setbacks, and lot coverage in New York City.
