About commercial districts
Commercial districts allow retail, office, and service uses, and most also allow housing under the rules of a residential-equivalent district. Commercial bulk is governed by § 33- 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.
