C1-7 Zoning is a Commercial Zoning district in NYC. It is a Local Retail and Local Service Commercial Zoning District. In C1-7 you can build a variety of commercial building uses, community facilities, and residential buildings. C1-7 zoning will have mostly residential buildings with commercial use on the lower floors. C1 Zoning has a low commercial FAR of 2 but these buildings can often have a residential development above the commercial spaces.
The C1-7 Zoning District is a sub district of C1 Zoning in NYC.

C1-7 Zoning Regulations
The C1-7 Zoning District is primarily residential with commercial uses on the street level. The East Village and West Village of Manhattan have C1-7 Zoning. 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.
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 C1-7. This analysis does not assume to cover every possible issue, but provide a general overview of the zoning codes.
C1-7 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. The residential equivalent for C1-7 is R8 Zoning.
Mixed Use Building
You can develop a mixed use building with commercial and residential zoning. In this case you would apply the requirements of C1-7 and R8 in designing a mixed use building. Because of the low Floor Area Ratio for C1-7 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.

C1-7 Commercial Floor Area Ratio (FAR):
Floor Area Ratio determines the floor area that can be built on the property.

Sometimes the FAR is higher for community facilities as it is in this case.
