Accessory Buildings

What is an accessory Building?

Accessory buildings are buildings that are separate from the principle building.

They could be used for either residential or agricultural purposes.

Garages, shops, sheds, gazebos, barns and shelters are all examples of accessory buildings.

Do I need a building permit?

You do need a building permit if your accessory building meets any of the following criteria for the definition of a building. [OBC Div. C 1.3.1.3 (4)]

You do not need a building permit for a shed which meets the following requirements [OBC Div. C 1.3.1.1 (6)] : 

• Is not more than 15 sq. m (161.5 sq. ft.).
• Is not more than one storey in building height.
• Is not attached to a building or any other structure.
• Is used only for storage purposes ancillary to a principle building on the lot.
