The Residential Apartment (RA) zones permit urban residential development and compatible institutional and semi-public buildings.

The RA zones are designed to be mapped in areas identified as moderate- or high-density residential areas suitable for multiple dwelling unit development and supporting uses.

The provisions of the RA zones are intended to:

  • Provide for the orderly development and use of land and structures in areas characterized by predominantly moderate- to high-density residential uses;
  • Permit flexibility by allowing all types of residential development;
  • Promote stable residential areas while permitting a variety of types of urban residential neighborhoods;
  • Promote a walkable living environment;
  • Allow limited non-residential uses that are compatible with adjoining residential uses;
  • Encourage compatibility between the location of new buildings or construction and the existing neighborhood; and
  • Ensure that buildings and developments around fixed rail stations, transit hubs, and streetcar lines are oriented to support active use of public transportation and safety of public spaces.
