Multifamily Residential District
Applied in multifamily residential General Plan categories and mixed use categories where there are existing or planned concentrations of multifamily uses, this district provides opportunities for a mix of predominantly attached residential development patterns. Higher densities (more than 15 units/acre) are generally located near thoroughfares, transit corridors, services and employment. Design standards are incorporated into the RM district to provide compatible transitions between higher density residential development and abutting lower density residential uses. This district provides for medium and higher density multifamily apartments, single-family attached and detached units, group residential, live-work housing, larger residential care facilities, and similar compatible uses such as day care. Existing mobile home parks are considered to be conforming uses. Bed and breakfast inns and public and quasi-public uses may also be allowed in appropriate locations at the discretion of the city.
