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.
