Castlegar permits for decks, sheds, carports and garages
Do I need a permit for a deck, shed, carport, or garage?
Short answer
In Castlegar any deck needs a building permit. A shed, garage or carport needs one if it is over 10 m². An accessory building under 3 m high and under 10 m² is outside the Building Bylaw, but it must still meet zoning setbacks. The City web page says 9.5 m², so confirm.
Key facts
| Sheds | A building permit is needed for an accessory building (shed) over 10 m² (s. 8.1(a)). One under 3 m high and under 10 m² is outside the Building Bylaw (s. 4.3(a)). Taller sheds of 10 m² or less are not clearly addressed; ask Development Services. All must meet zoning setbacks. The City web page says 9.5 m².Sources differ: The City web page says garden sheds up to 9.5 m² need no permit (and accessory buildings larger than 9.5 m² do). The bylaw says 10 m². Value follows the bylaw. Section 4.3(a) says under 3 m high and under 10 m²; an accessory building of exactly 10 m² or exactly 3 m high is not clearly covered either way.Building Bylaw 1338 (consolidated, PDF), s. 4.3(a), s. 8.1(a) · Wording matched the official text retrieved 2026-11-06Official wordingan accessory building less than 3 metres in height and with a floor area of less than constructing, repairing or altering a building or structure, if it exceeds ten (10) square |

How it works
Under Building Bylaw 1338, the City of Castlegar requires a building permit for any deck, with no height or size threshold. An accessory building such as a shed, garage or carport needs a permit if it is over 10 m². One that is under 3 m high and under 10 m² is outside the bylaw. Carports are not named in the bylaw or the City page.
Every accessory building must still meet the setbacks in Zoning Bylaw 1428, whether or not it needs a permit.
Steps
- Measure the floor area and height. A deck, or an accessory building over 10 m², needs a permit.
- Draw a site plan showing the structure and its distance to every lot line and to the house.
- Email the application and plans to devserv@castlegar.ca or apply in person at City Hall.
- Fees are calculated after review. Book inspections as the work goes on.
Good to know
- Zoning setbacks and limits for an accessory building in R1, R2 and R3 zones: at least 6.0 m from the front lot line, 3.0 m from an exterior side line and 1.5 m from interior side and rear lines. It can be at most 7.5 m high (or 0.5 m lower than the house, whichever is less) and no more than 80% of the size of the main dwelling. Other zones differ, so look up your zone.
- An accessory building cannot be built before the principal building. It may not contain a dwelling unit unless it conforms to the Zoning Bylaw (see secondary-suite).
- The City web page says sheds up to 9.5 m² need no permit; the bylaw says 10 m². A taller shed of 10 m² or less is not clearly addressed, so ask Development Services.
- A setback violation can bring a municipal ticket of $200 for a first offence and $400 for a second (Municipal Ticketing Bylaw 1179).
