18.20.100 R-4 (Residential Medium-Density Multifamily)
Purpose: The R-4 (Medium-Density Multifamily) District provides for well-designed multifamily complexes with emphasis on open space and access to light and air. Multifamily projects in the R-4 district are low-rise developments with commonly maintained landscaped open space. The R-4 district allows development of up to eighteen (18) to twenty-nine (29) dwelling units per net acre, depending on the standards that are used. R-4 implements the Conventional Residential Neighborhood and Conservation/Cluster Neighborhood future land use categories and the following Comprehensive Plan policies:
•LUCC 3.1: Encourage housing near services.
•LUCC-3.3: Ensure that zoning allows for a variety of home types and lot sizes.
•LUCC-8.2: Use zoning as a tool to avoid or minimize conflicts between land uses.
•HN-2.1, HN-2.5, HN-4.1, and HN-4.2: Provide a full range of housing choices, affordable housing, and neighborhoods that enable residents to “age in place.”
