Can I add a secondary suite or a carriage house in Cache Creek?

Cache Creek, British ColumbiaChecked against official textSources read 2026-11-08

Short answer

Yes, in Cache Creek, in some zones. The Zoning Bylaw permits an attached accessory dwelling unit in the R1 zone (and an accessory dwelling unit in AR1 and AR2), and a detached one in R1. You need a single detached dwelling, plus municipal water and sewer or a lot over 1.0 ha.

Key facts

Secondary suite allowedYes. An attached accessory dwelling unit is a permitted accessory use in the R1 zone, and an accessory dwelling unit in AR1 and AR2. It needs a single detached dwelling and municipal water and sewer, or a lot over 1.0 ha.Zoning Bylaw No. 6-010, 2026, s. 8.4.3 R1; Zoning Bylaw No. 6-010, 2026, s. 5.1.1 · Wording matched the official text retrieved 2026-11-08

How it works

Under the Village's Zoning Bylaw No. 6-010 an accessory dwelling unit (ADU) is a separate dwelling established by permit. In R1, one attached and one detached ADU are permitted accessory uses, but not on a two-unit dwelling. AR1 and AR2 list "Accessory Dwelling Unit" without type. R2 allows one only with a single-detached dwelling that existed at adoption, and C1 and C2 allow them as an accessory use.

Limits:

  • Attached: up to 60% of the home's habitable floor space (main floor, garage conversion, above-garage or upper storey), or 100% of a basement.
  • Detached: up to 95 m² on lots under 1,000 m² and 140 m² on larger lots, and no more than 60% of the principal dwelling's floor area. It must be 3.0 m from the house, have a separate entrance, and have no roof-top decks.
  • An ADU cannot be strata-subdivided.

Steps

  1. Confirm your zone (see the zoning-lookup answer).
  2. Check you have a single detached dwelling and municipal water and sewer, or a lot over 1.0 ha.
  3. Ask the Village Office whether other permits apply.
  4. Apply for a building permit through the TNRD (see the building-permit answer).

Good to know

  • Parking: one additional stall per ADU.
  • The TNRD lists converting a suite to a rental unit as work needing a building permit.
