Can I Build a Garage Suite in Calgary?
Zoning and Permits in Calgary
Garage suites are permitted in most residential zones across Calgary, including R-1, R-2, and some R-MH zones. However, you must obtain a development permit from the City of Calgary before construction begins. The City reviews your plans against current zoning bylaws to ensure compliance.
After development permit approval, you’ll need a building permit, which verifies your design meets the Alberta Building Code (ABC).
Key Requirements
- Setback compliance: Must respect front, rear, and side yard setbacks for your zone
- Separate utilities: Gas, electric, and water connections independent from the main home
- Egress window: Minimum 0.5 m² operable window (6” minimum sill height) for bedroom safety
- Parking: Some zones require 1-2 additional parking spaces
- Lot size: Typically requires minimum 500-600 m² depending on zoning
