R-4 Multifamily Residential District

The R-4 district is a multifamily medium to high density residential district. It is intended primarily for multifamily and multi-story residential buildings, but also allows single-family, duplex, and townhouse residential development. For multi-story buildings, the maximum size of buildings and intensity of use is regulated by floor area ratio (FAR) and other site development standards. Multi-story development is intended to be applied in areas well served by transit and/or arterial streets, and by supportive commercial services near the major commercial and employment centers in downtown and midtown. Although some commercial development is allowed within a residential development, the district is intended to be primarily residential. For multi-story buildings, development is intended to be oriented to the sidewalk with windows, entrances, and walkways to provide strong pedestrian connections to nearby services.

See AMC 21.04 for District-Specific Standards.
