How it works

Under s. 23 of the Land Use Bylaw No. 259, a secondary suite inside the principal dwelling is allowed in zones that list accessory dwelling units: Agricultural, Upland, Rural, Amenity Residential, Rural Residential, Commercial 2 and Commercial Recreation. On lots under 0.8 ha (1.98 acres) it is the only accessory dwelling unit allowed.

On lots of 0.8 ha or more, a detached secondary suite or carriage house is also allowed. Outside the Agricultural Land Reserve (ALR) you may have one accessory dwelling unit of any type. In the ALR you may have one secondary suite plus one detached suite or carriage house. A carriage house has living space on the upper floor above an accessory building such as a garage or workshop.

Steps

  1. Confirm your zone and lot size with Municipal Hall (250-474-3167).
  2. Check size limits and parking (below).
  3. Apply for a building permit. Before it is issued you must show CRD water or adequate well water (3,400 L/day) and an approved sewage disposal system. Detached suites also need a Homeowner Protection Office declaration.
  4. Ask staff whether development permit areas or a tree cutting permit apply to your lot.

  • A detached suite or carriage house may not have separate road access. A suite cannot be strata titled or subdivided.
  • Parking: two off-street spaces for the suite, in addition to two for the main dwelling. A front-yard driveway leading to a space that is not in the front yard may count as the second space.
