The residential multifamily group includes two zone districts: R-2 and RM-2. It is the intent of these districts to provide for residential areas of medium to high density and only when community potable water systems and centralized sanitary sewer systems are available and accessible. These zoning districts allow for a desirable variety of housing types together with public and semipublic buildings and facilities and accessory structures as may be compatible with residential development. Nonresidential uses in these districts may be subject to restrictions and requirements necessary to preserve and protect the residential character of these districts. Variation between the R-2 and RM-2 districts is in requirements for density (land area per dwelling unit and the use of mobile homes in RM-2). Permitted densities in both districts increase with the provision of city water and sewer services.
