Short answer

Yes. Radium Hot Springs allows an attached suite (in a basement, a storey or a converted garage) with a one-unit or two-unit home in the R2, R3, R4, R5, RTA and AG zones. A detached suite (coach house or garden suite) is allowed only where the zone lists it. A building permit is needed.

How it works

Suites are regulated in ss. 4.1 and 4.2 of the Zoning Bylaw No. 528.

Attached suite. An attached accessory dwelling unit (in a basement, a storey or a converted garage) is allowed as an accessory use to a one-unit or two-unit residential building, one per principal dwelling unit. It is a listed accessory use in the R2, R3, R4, R5, RTA and AG zones. Size: up to 100% of the basement (or first storey) for existing buildings; for new construction, 100 m² or 50% of the first storey, whichever is greater.

Detached suite (coach house or garden suite). Allowed only on a parcel with a one-unit residential building, where the zone lists it, and not on a parcel that has an attached suite. It must be on the community water and sewer systems. It may be 95 m² on parcels under 1,000 m² or 140 m² on larger ones, and no more than 75% of the main dwelling's floor area. It must be at least 3.0 m from the house, have a separate entrance and have no roof-top deck.

No suite may be subdivided or stratified. R2 allows 2 dwelling units per parcel and R3 allows 3, including suites.

Parking: one off-street space per bedroom of the suite, up to a maximum of 2. No visitor parking is required.

Steps

  1. Check your zone. See the zoning-lookup answer.
  2. Confirm the size limits above.
  3. Apply for a building permit; one is needed for new construction and for changes, alterations or additions to existing buildings.
  4. Ask Building and Development Services whether a development permit is also needed.

Good to know

  • Whether the C zones allow a suite was not checked here.
  • The Village's pages do not say whether a development permit (the wildfire area covers all Village land) is needed for a suite. Wildfire development permit applications have no fee.
  • We did not find a rule requiring the owner to live on the parcel for a long-term suite. An owner or long-term tenant must live there for a short-term rental suite; see the short-term-rental answer.
