The exemption (s. 7.19) covers a single-storey accessory building, or an unmodified shipping container, serving a one- or two-family home, if its floor area is 15 m² (161.4 ft²) or less. Zoning rules on setbacks, height and lot coverage still apply even when no permit is needed.\n\n## Steps\n\n1. Confirm your zoning, setbacks, height and lot coverage with Development Planning (604-820-3748) or the City's WebMap before you design.\n2. Download the Accessory Building or Residential Decks checklist and gather the forms, plans, survey and title search.\n3. Start with a Pre-Submission Review, then pay the non-refundable application fee when the application is accepted.\n4. Pay the permit fee before the permit issues, then book inspections online.\n\n## Good to know\n\n- Decks: the City lists \"adding or increasing a deck\" as needing a building permit, and detached deck structures over 15 m² also need one. No minimum deck height is stated.\n- Garages and carports: a detached garage or carport over 15 m² needs a permit, and so does converting a carport into a garage or living space.\n- Pool houses: the City's page says a pool house (shed) needs a permit regardless of size, but the bylaw exempts accessory buildings of 15 m² or less. Confirm with Inspection Services.\n- Accessory-building setbacks, height and lot coverage are set zone by zone in the Zoning Bylaw. Buildings that need no permit are exempt from interior side and rear yard setbacks. A building joined to the house by a continuous foundation, walls and roof is treated as part of the house.\n- Sealed sprinkler plans are needed if the floor area is over 100 m² or over 50% of the principal building's floor area, whichever is less.\n- Starting work before the permit issues increases the fee by 100%, or $250 if that is greater.\n- Electrical and gas permits come from Technical Safety BC (1-866-566-7233), not the City.","sources":[{"url":"https://www.mission.ca/building-permits","title":"Building Permits, City of Mission","accessed":"2026-11-05"},{"url":"https://www.mission.ca/media/file/building-bylaw-3590-2003pdf-1","title":"Building Bylaw 3590-2003 (PDF, consolidated), sections 7.19 and Schedule A","accessed":"2026-11-05"},{"url":"https://www.mission.ca/media/file/5949-2020-zoning-bylaw-completepdf","title":"Zoning Bylaw 5949-2020 (PDF), s. 104 H","accessed":"2026-11-05"},{"url":"https://www.mission.ca/media/file/accessory-building-submission-checklist","title":"Accessory Building Submission Checklist (PDF), City of Mission","accessed":"2026-11-05"},{"url":"https://www.mission.ca/media/file/residential-decks-submission-checklist","title":"Residential Decks Submission Checklist (PDF), City of Mission","accessed":"2026-11-05"},{"url":"https://www.mission.ca/webmap","title":"WebMap, City of Mission","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 5 of 5 facts was matched to the official text."},"urls":{"html":"https://govhandbook.com/ca/bc/mission/deck-shed-garage-permit/","markdown":"https://govhandbook.com/ca/bc/mission/deck-shed-garage-permit.md","json":"https://govhandbook.com/ca/bc/mission/deck-shed-garage-permit.json"}}
