The City's Building Permits page says any new building over 10 m² (108 sq ft) needs a permit, and so does a smaller one that poses a risk or hazard. It also lists decks, new roofs over decks, and exterior decks above ground level. It states no deck height threshold. The zoning bylaw names garages and carports as accessory buildings, so the same rule applies.\n\n[Zoning Bylaw 3652](https://nelson.civicweb.net/document/31803) applies whether or not you need a permit. Limits are set zone by zone, so check your zone. Decks and structures over 0.6 m above grade count toward lot coverage.\n\n## Steps\n\n1. Find your zone and its height, setback and coverage limits (see the zoning-lookup answer).\n2. Download the Decks and Porches or Detached Accessory Buildings checklist.\n3. Submit the building permit application, checklist items and fee to Development Services on the second floor of City Hall.\n\n## Good to know\n\n- Example from the R1 zone: accessory buildings up to 4.5 m high; carports 1.5 m and other accessory buildings 3 m from the front lot line; at least 1.5 m from the rear lot line; at least 1 m from the house (a carport may attach on one side); lot coverage 35% for one dwelling unit. Other zones differ.\n- R1 side setbacks for accessory buildings are 1.2 m if the front lot line is wider than 9.2 m, otherwise 1 m.","sources":[{"url":"https://www.nelson.ca/162/Building-Permits","title":"Building Permits, City of Nelson","accessed":"2026-11-05"},{"url":"https://nelson.civicweb.net/document/77460","title":"Building Bylaw No. 3456, 2019 (Consolidated, PDF)","accessed":"2026-11-05"},{"url":"https://nelson.civicweb.net/document/31803","title":"Zoning Bylaw No. 3652, 2026 (PDF)","accessed":"2026-11-05"},{"url":"https://nelson.civicweb.net/document/6404","title":"Fees and Charges Bylaw No. 3092 (Consolidated, revised April 28, 2026, 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 5 of 5 facts was matched to the official text."},"urls":{"html":"https://govhandbook.com/ca/bc/nelson/deck-shed-garage-permit/","markdown":"https://govhandbook.com/ca/bc/nelson/deck-shed-garage-permit.md","json":"https://govhandbook.com/ca/bc/nelson/deck-shed-garage-permit.json"}}
