Osoyoos permits for decks, sheds, carports and garages
Do I need a permit for a deck, shed, carport, or garage in Osoyoos?
In Osoyoos a shed or other accessory building in a residential zone needs no building permit if it is no more than 10 m² and 4.5 m high. The Town's page says 10 m² and larger need a permit. The bylaw sets no deck threshold; ask Planning.

How it works
Sheds and other accessory buildings. Under the Building Code Administration Bylaw No. 1251, no permit is needed for an accessory building in a residential zone that does not exceed 10 m² in area and 4.5 m in height. Larger or taller ones need a permit. The Town's permits page says accessory buildings of 10 m² and larger need a permit, so a building of exactly 10 m² is unclear. Confirm with Planning.
Garages and carports. Neither is named in the building bylaw or on the permits page. A detached garage is an accessory building, so the same 10 m² and 4.5 m threshold applies. The bylaw does not mention carports separately.
Decks. The building bylaw, the permits page and the Zoning Bylaw No. 1395 state no height or size threshold for decks. Ask Planning and Development Services (250-495-6191).
Steps
- Check the size and height of what you plan to build against the 10 m² and 4.5 m threshold.
- Check your zone's rules (see below), and that the lot already has a principal building.
- If a permit is needed, follow the building-permit answer. A foundation design is normally required but may be waived for detached accessory buildings under 55 m².
Good to know
- In the RS1 (Small-Scale Multi-Unit Residential) zone an accessory building may be up to 4.5 m high. Setbacks are 3.0 m front, 2.0 m rear, 1.2 m interior side and 3.0 m exterior side. All buildings together may cover up to 50% of the parcel. Other zones have their own numbers.
- An accessory building cannot sit between the front lot line and the house, and cannot contain bedrooms, kitchens, bathrooms or decks.
- Zoning limits apply even where no permit is needed.
- A zoning ticket for an accessory building used contrary to the rules is a $100 bylaw notice ($90 early, $110 late).
