Detached Garages and Sheds
Permits, application requirements and general rules
Before building a detached garage or other accessory building on your property, it is important to first obtain necessary permits. This will ensure that your project meets regulatory requirements and will help you avoid the distress of resolving deficiencies.

A detached garage is a detached accessory building that is more than 10m2 in gross floor area and is associated with a residential use. Garages may have various purposes, such as for vehicles, storage, work space, etc.


If the intended purpose of an accessory building is to provide living space for people, it is considered an Accessory Dwelling. To see the requirements for this type of development, visit Secondary Suites.
