Basement Suite Development

On May 22, 2007, City Council passed amendments to the Land Use Bylaw to enable the development of basement suites within single detached dwellings in the City. This change not only allows for previously unauthorized basement suites to be approved, but also new basement suites in either an existing home or as part of new house construction. The following applies to basement suite development in the City:

One basement suite is allowed within the basement level of a single-detached house. Suites within duplexes or townhouses, above garages or on upper levels of a home are not permitted.

  • Basement suites shall be an accessory (i.e. incidental/secondary) to the principal dwelling unit.
  • A maximum of 3 bedrooms is allowed within a basement suite.
  • Basement suites must have a minimum floor area of 30 square metres (323 square feet).
  • A separate entry for the basement suite, either from a common landing or from the exterior, is required. If the entry is from the exterior, it shall be located on the side or rear of the principal dwelling unit.
  • Parking required: 1 on-site parking stall is required for a basement suite unless it is a 3-bedroom suite, in which case 2 parking stalls are required (note: 2 parking stalls are required for a single detached house; required parking for basement suites is in addition to these 2 stalls).

A development permit (and a building permit) must be obtained prior to the construction of a new basement suite or for the approval of an existing suite.
