Mixed-use zoning is a classification that permits both residential and commercial uses within the same building or district, rather than restricting a lot to a single use type.

In C4 and C6 commercial districts, a developer can build apartments above ground-floor retail. In designated Mixed Use districts like M1-1/R6A, residential and light manufacturing uses are permitted on the same block. On wide streets, ground-floor commercial use is often required or strongly incentivized. The Zoning Resolution specifies which uses are permitted as-of-right and which require a special permit in each mixed-use designation.

Mixed-use zoning typically expands the pool of potential buyers for a development site. Both residential and commercial developers can bid, which tends to support stronger land pricing than single-use districts. Many owners assume mixed-use zoning requires a commercial component, but in most NYC mixed-use districts, residential-only development remains fully permitted as-of-right.

More permitted uses means more potential buyers, and more buyers means stronger pricing for your land.

Example: A 5,000 SF lot in a C4-4 district (FAR 3.4) supports 17,000 buildable SF that can be developed as residential, commercial, or a combination of both — giving a developer flexibility that a purely residential R7A lot simply doesn't offer.
