The Residential Flat (RF) zones are residential zones, which provide for areas developed primarily with row dwellings, but within which there have been limited conversions of dwellings or other buildings into more than 2 dwelling units.

The RF zones are designed to be mapped in areas identified as low-, moderate-, or medium-density residential areas suitable for residential life and supporting uses.

The RF zones are intended to:

  • Recognize and reinforce the importance of neighborhood character, walkable neighborhoods, housing affordability, aging in place, preservation of housing stock, improvements to the overall environment, and low- and moderate-density housing to the overall housing mix and health of the city;
  • Allow for limited compatible non-residential uses;
  • Allow for the matter-of-right development of existing lots of record;
  • Establish minimum lot area and dimensions for the subdivision and creation of new lots of record in RF zones;

  • Allow for the limited conversion of rowhouse and other structures for flats; and
  • Prohibit the conversion of flats and row houses for apartment buildings as anticipated in the RA zone.
  • The RF zones shall be distinguished by a maximum number of principal dwelling units per lot of either 2, 3, or 4 units.
    The development standards are intended to:
  • Control the bulk or volume of structures, including height, FAR, and lot occupancy;
  • Control the location of building bulk in relation to adjacent lots and streets, by regulating rear setbacks, side setbacks, and the relationship of buildings to street lot lines;
  • Regulate the mixture of uses; and
  • Promote the environmental performance of development.
