Yes, in many zones. The City of Powell River allows one secondary suite inside a single-family dwelling (or duplex in most zones) and one carriage house per lot up to 120 m² (1,291 sq ft), depending on zone. Register a suite with the City and have it inspected before anyone lives in it.

How it works

In the City of Powell River, the Zoning Bylaw allows one secondary suite inside a single-family dwelling or duplex in R1, R2, R3, R3A, RA1, A0, A1, CD3 and CD4 zones. In the A2 and MC (Milltown Centre) zones, a suite is allowed in a single-family dwelling only. The City's older information sheet lists fewer zones and says suites are not permitted in compact or multi-family zones; the bylaw is followed here.

The suite must be wholly inside the main dwelling, with a heated interior connection and its own separate entrance. One suite per dwelling. On lots over 4,050 m², the zone allows only three dwelling units in total, and the suite only in a single-family dwelling. The bylaw sets no minimum unit floor area and no owner-occupancy rule.

A carriage house (a detached dwelling behind the main house) is allowed, one per lot, up to 120 m² (1,291 sq ft), in R1, R2, R3, R3A, RA1, A0, A1, A2, CD3 and CD4 zones. It must be at least 1.8 m from side and rear lot lines (3.0 m in A0, A1 and A2) and 4 m from the main building, and no higher than the zone's accessory building height.

Steps

  1. Confirm your zone allows a suite or carriage house in the Zoning Bylaw, or call Planning at 604-485-8650.
  2. For a suite, complete the Secondary Suite Declaration Form and submit it to the City. The Building Inspector inspects it before anyone occupies it.
  3. A building permit is needed for construction, structural or plumbing work. A carriage house needs a development permit application and a building permit.
  4. Provide parking on the lot: 1 space per dwelling unit for up to four units (not apartments), to a maximum of 3 spaces per lot.

Good to know

  • Failing to declare a suite can bring fines or an order to stop tenant occupancy. The zoning ticket for an unlawful secondary suite is $200.
  • Once registered, your tax account gets an extra garbage levy and residential water levy. Ask Finance for the amounts.
  • The City's Carriage Houses web page omits CD3 from its zone list; the bylaw includes it, so confirm with Planning.
