C4-2 Residential Equivalent

Most Commercial Zoning districts have a Residential Equivalent. This means you are allowed to develop a residential building within the commercial zoning district. You follow the residential equivalent zoning requirements in the case of a residential development. The residential equivalent for C4-2 is R6 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 C4-2 and R6 in designing the building.
