C2-7A Zoning Regulations
The C2-7A Zoning District is primarily residential with commercial uses on the street level. C2-7A Zoning is mapped in a few areas of Manhattan mostly on the Upper West Side. 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.
C2-7A Residential Equivalent
Most Commercial Zoning districts have a Residential Equivalent. This equivalent is the Residential Zoning you would comply with when developing a residential building or mixed use building. The residential equivalent for C2-7A is R9A Zoning.
Mixed Use Building C2-7A
You can develop a mixed use building with commercial and residential zoning. In this case you would apply the requirements of C2-7A and R9A in designing a mixed use building. Because of the low Floor Area Ratio for C2-7A 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.
