In Fort St James a secondary suite is allowed in a single-detached dwelling in the R1, R4, RR1, RR1A, RR2 and RR3 zones (not R2 or R3). Detached garden suites are allowed on RR1, RR2 and RR3 lots. Both need a building permit and must be registered with the District for utility billing.

How it works

Zoning Bylaw No. 1101 permits a secondary suite in a single-detached dwelling. It is a listed use in the R1, R4, RR1, RR1A, RR2 and RR3 zones, but not R2 or R3. Garden suites (a detached suite) are permitted on lots zoned RR1, RR2 and RR3 that have a single-detached dwelling as the principal use. In R1, one detached secondary dwelling is allowed only on one named parcel (Plan PRP3304).

Limits: one secondary suite per single-detached dwelling, and both units are one real estate entity. No suite is allowed on a lot with a garden suite. A garden suite is one per lot, no closer to the front lot line than the house, in an accessory building up to 37 m² floor area.

Steps

Check your zone with the District office (250-996-8233) and confirm a suite is allowed on your lot.
Apply for a building permit to build a new suite or renovate an existing one, with the form, a title search made within 30 days (or the current tax assessment notice), floor plans and a cross section.
Register the suite with the District for utility billing.

Good to know

Properties with a secondary or garden suite pay an extra 40% of the principal dwelling's utility fees, twice yearly.
The District's own suite page cites the old Zoning Bylaw 738 and different zones. The 2025 bylaw is followed here; confirm with the District.
The zoning bylaw sets no suite size limit, no owner-occupancy rule and no extra parking for a suite that we could find. Ask the District.
Official Community Plan development permit areas may apply to some lots.
