Two common forms
Backyard suite
A separate dwelling behind the main home, such as a suite above a garage. Follow the City’s dedicated backyard suite guidance.
Step by step
Identify the space and intended use
A kitchen or separate entrance alone does not establish legal status. Determine whether it is an existing suite, new secondary suite or separate backyard suite.
Visit the official resource ↗Check the address and registry
For an existing suite, review the official Suite Registry, permits and inspections, and compare the actual layout with the records. Ask the City about a missing registration.
Visit the official resource ↗Prepare the required permits
New suites need a building permit. Electrical or plumbing work can require trade permits; a development permit depends on the land use and design. Check with the City first.
Visit the official resource ↗Complete approved work and inspections
Review bedroom egress, smoke and carbon monoxide alarms, fire separation, entrances and other applicable requirements with qualified professionals. Complete required inspections before confirming use.
Visit the official resource ↗Confirm registration and rental use
Keep permit, inspection and registration records. Confirm rental use with your insurer and lender. Short-term rental use also requires a separate review of Calgary business licensing.
