The intent of the residential districts is to provide zoning districts in which the predominate use will be residential, while providing for those uses that are generally considered residential in character, or that serve the immediate needs of their residential neighborhoods. It is further the intent of these regulations to permit the orderly development of the full range of residential uses and reuses in keeping with the character of the neighborhoods within which such uses take place.
A. 
R-1 Zoning District. To provide a zoning district in which the predominate use will be single-family homes with height and area regulations establishing an intensity of land use designed to effect low-density residential development therein.
B. 
R-2 Zoning District. To provide a zoning district in which the predominate use will be residential with height and area regulations establishing an intensity of land use designed to encourage the proper development of single- and two-family dwellings.
C. 
R-3 Zoning District. To provide a zoning district in which the predominate land use will be residential and provide for dwelling unit types and densities that permit the development of single-family and two-family dwellings and encourage the construction of medium-density, multifamily developments.
D. 
RM-3 Zoning District. To provide a zoning district that accommodates the development of health services in a transitional residential area located adjacent to a major hospital.
