C2-1 Zoning NYC

(Last Updated On: November 10, 2018)

C2-1 Zoning is a Local Retail and Local Service Commercial Overlay Zoning District in NYC. As a commercial overlay C2-1 is mapped in residential Zoning Districts and allows for commercial use in residential zones.

 

C2-1 Zoning

The C2-1 Zoning District is a sub district of C2 Commercial Overlay Zoning in NYC.

C2 Zoning Commercial Overlay Districts:

 

C2-1 Commercial Overlay

A Commercial Overlay is a Commercial Zoning District mapped in Residential Zoning Districts. These allow for commercial building to be built in residential zones. You can also build a mixed use building which is common with commercial on the ground floor and residential above.

 

C2-1 Zoning Regulations

The C2-1 Zoning District is primarily residential with commercial uses on the street level. The commercial uses are usually typical commercial uses for residential areas including retail, restaurants and services for the day to day needs of a residential neighborhood. You can find C2-1 in The Bronx, Queens, and Staten Island.

As an architect I study zoning very closely, it is complicated and quite involved. In this article we will review some of the basic Zoning Codes with regards to commercial zoning district C2-1. This analysis does not assume to cover every possible issue and condition, but provide a general overview of the zoning codes.

 

Mixed Use Building

You can develop a mixed use building with commercial and residential uses. In this case you would apply the requirements of C2-1 and the residential zoning district in which it is located. Because of the low Floor Area Ratio for C2-1 it would be most likely that a new development would have residential use above the commercial floor(s) in order to maximize the development potential.

The commercial and residential FARs are not added together. The maximum FAR for the building is whatever FAR is larger. Each use cannot exceed its individual FAR. And the building cannot exceed the largest of the individual FARs.

Example if you have a commercial overlay FAR of 1 and a Residential FAR of 3 the total building FAR is 3. The commercial floor area cannot exceed an FAR of 1 in this case.
