About residential districts

Residence districts principally allow housing and community facilities. Bulk rules in the NYC Zoning Resolution (§ 23-) control how much floor area a lot can carry and how tall and close to lot lines a building may be.

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.
