Secondary suites and cottages are regulated by the Islands Trust through [Land Use Bylaw No. 355](https://islandstrust.bc.ca/document/ssi-ltc-bylaw-no-355/), separately from the building permit, which the CRD issues.\n\nA secondary suite is allowed on lots within or partly within the shaded area of the bylaw's Schedule I (Secondary Suites Map), and on lots zoned Agriculture 1 or Agriculture 2 in the Agricultural Land Reserve. The owner, or a person responsible for managing the property, must live in the dwelling or the suite.\n\n## Steps\n\n1. Check whether your lot is in the shaded area of Schedule I, or is zoned Agriculture 1 or 2 in the Agricultural Land Reserve. Ask the Islands Trust to confirm.\n2. Check the suite limits: one suite per lot, inside the walls of the building with the main dwelling, with a separate outside entrance, up to 90 m². A suite cannot be subdivided or stratified. Lots on groundwater need enough water.\n3. Plan parking: one space per suite, in addition to the 2 spaces for the single-family dwelling.\n4. Get the Islands Trust to confirm land-use compliance (Building Permit Review Response Form). A development permit may also be needed if the lot is in a development permit area.\n5. Apply to the CRD for a building permit to fully legalize the suite. The CRD requires proof of potable water and septic capacity.\n\n## Good to know\n\n- A detached suite is not allowed. A detached full-time rental cottage is allowed only where a zone variation permits it (R7(a), R(f), RU1(f)), on lots of 1.2 ha or more, up to 56 m² on lots under 2 ha or 90 m² on lots of 2 ha or more.\n- Seasonal cottages cannot be lived in full time.\n- The Schedule I map is an image. Ask the Trust if you cannot tell whether your lot is inside the shaded area.","sources":[{"url":"https://islandstrust.bc.ca/document/ssi-ltc-bylaw-no-355/","title":"Salt Spring Island Land Use Bylaw No. 355 (PDF), sections 3.14 to 3.16 and Table 3","accessed":"2026-11-05"},{"url":"https://islandstrust.bc.ca/document/salt-spring-island-schedule-i-secondary-suites-map-lub-bylaw-355/","title":"Schedule I Secondary Suites Map, Land Use Bylaw 355","accessed":"2026-11-05"},{"url":"https://www.crd.ca/media/file/building_permit_guide","title":"CRD Building Permit Guide (PDF)","accessed":"2026-11-05"}],"sources_read":"2026-11-05","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/salt-spring-island/secondary-suite/","markdown":"https://govhandbook.com/ca/bc/salt-spring-island/secondary-suite.md","json":"https://govhandbook.com/ca/bc/salt-spring-island/secondary-suite.json"}}
