RI 5
Single-Family Infill District
This district implements the single-family infill category of the General Plan and applies in areas that are primarily of single-family detached housing, although duplexes, triplexes and attached single-family homes also exist and may be permitted. RI areas include subdivisions typically with regular lot patterns, varied designs and a limited mix of unit types. Where there is an established neighborhood character, new development should respect that visual character, especially as viewed from the street. This district provides for low density detached and attached single-family homes, accessory dwelling units, clustered and planned developments, duplexes and triplexes, mobile homes, manufactured housing, and compatible uses such as day care and smaller residential care facilities. Bed and breakfast inns, and public and quasi-public uses may also be allowed in appropriate locations at the discretion of the city.
