Detached Garage

A BUILDING PERMIT IS REQUIRED for a garage. A development permit is not required for a garage serving a single family dwelling provided it complies with the requirements of the Land Use Bylaw. Please allow approximately 1 to 2 weeks to process an application.

General Information

It is recommended that garages over 55 square meters (592 square feet) in building area have foundation walls and footings a minimum of 1.2 meters (3.93 feet) below grade around the perimeter or the design of the foundation should be reviewed by a Professional Engineer licensed to practice in the Province of Alberta. Contact the Building Inspector about possible alternative foundation designs for garages larger than 55 square meters (592 square feet).

The maximum height of a detached garage cannot exceed 4.5 meters (14.7 feet). Height is determined from the average lot grade to the peak of the roof.

A detached garage cannot be located in a front yard.

Maximum lot coverage for all accessory buildings on a residential lot is 15%.
