It is a permitted accessory use in the A1, A2, R1, R2, R3, R4 and R99 zones, and some others. In A2, R2 and R3 it is not permitted on a lot under 1 ha unless an onsite wastewater practitioner or engineer provides a report.\n- **Carriage house or garden suite:** a detached unit, 20.5 m² to 90 m². Allowed in R1; in R2, R3 and R4 only on a lot of 1 ha or more; in A1 only on a lot of 4 ha or more. A garden suite is one storey, up to 4.5 m high. A carriage house is two storeys over required parking, up to 8 m. In R1 a detached unit is not permitted in the front yard setback area.\n\nLimits: R1 allows a single-detached dwelling with up to 2 or 3 accessory dwelling units, depending on lot size (under or over 280 m²). R2 allows one secondary suite, or one carriage house or garden suite on 1 ha or more. A1 allows one suite, with no strata titling. Parking is 1 space per accessory dwelling unit, in addition to 2 spaces for the single-detached dwelling.\n\n## Steps\n\n1. Find your zone (see zoning-lookup) and read its secondary suite and detached unit rules.\n2. Call Planning on 250-545-5304 to confirm that a suite is allowed on your lot and whether a development permit area applies.\n3. Apply for a building permit. The District lists \"Single Family Dwelling with Suite\" as a permit type.\n4. Book the secondary suite inspection ($100; re-inspection $50).\n\n## Good to know\n\n- Other zones (multi-family, commercial and comprehensive development) were not checked. Check your zone.\n- No owner-occupancy requirement for suites was found in the Zoning Bylaw. Ask Planning if you want it confirmed.\n- A suite cannot be used as a Bed & Breakfast or short-term rental.\n- A development permit may be needed first in a development permit area.","sources":[{"url":"https://coldstream.civicweb.net/document/104562/","title":"Zoning Bylaw No. 1838, 2024, consolidated to June 8, 2026, District of Coldstream","accessed":"2026-11-06"},{"url":"https://coldstream.civicweb.net/document/203/","title":"Building Bylaw No. 1758, 2021, District of Coldstream","accessed":"2026-11-06"},{"url":"https://coldstream.civicweb.net/document/1384/","title":"Miscellaneous Fees and Charges Bylaw No. 1541, 2008, District of Coldstream","accessed":"2026-11-06"},{"url":"https://www.coldstream.ca/sites/default/files/2022-11/FAQ%20BLDG%20PERMITS%20%283%29.pdf","title":"Building Permits FAQ (PDF, April 2021), District of Coldstream","accessed":"2026-11-06"},{"url":"https://www.coldstream.ca/municipal-hall/contact-directory","title":"Contact Directory, District of Coldstream","accessed":"2026-11-06"}],"sources_read":"2026-11-06","review":{"status":"machine_checked","badge":"Checked against official text","label":"Checked by script, not yet by a person: the official wording behind 6 of 6 facts was matched to the official text."},"urls":{"html":"https://govhandbook.com/ca/bc/coldstream/secondary-suite/","markdown":"https://govhandbook.com/ca/bc/coldstream/secondary-suite.md","json":"https://govhandbook.com/ca/bc/coldstream/secondary-suite.json"}}
