The Income Appeal of Calgary Basement Suites
A legally permitted basement suite in Calgary can generate $1,100–$1,600/month, dramatically offsetting mortgage costs. But many Calgary homeowners rent out unpermitted suites without realizing the legal and financial exposure this creates. Here's how to do it right.
Is Your Suite Legal?
A legal secondary suite in Calgary must: be located in a zone that permits secondary suites (most RS1 and R-C2 zones), comply with the Alberta Building Code and Calgary's Land Use Bylaw, have been permitted and inspected by the City of Calgary, meet minimum ceiling height requirements (typically 1.95m/6.4 feet), and have separate entrance and egress windows in bedrooms.
Getting a Permit
If your suite is unpermitted, you can apply for a development and building permit through the City of Calgary. The process involves plans review, inspections for electrical, plumbing, HVAC, and structural compliance, and usually costs $500–$2,000 depending on the work needed. Many suites need upgrades to pass.
Insurance Implications
An unpermitted rental suite can void your home insurance if the insurer discovers it. Always disclose rental activity to your insurer and obtain proper landlord coverage. Some insurers specialize in owner-occupied rental properties.
Income Potential
Calgary basement suite rents range from $1,100 (older suites in outer suburbs) to $1,600+ (newer suites in inner-city neighbourhoods). 1-bedroom suites in walkable areas like Marda Loop, Kensington, and Inglewood command premiums.
Landlord Obligations
A basement suite tenancy is subject to the full Alberta Residential Tenancies Act — you're a landlord, not just a homeowner with a roommate. All rules on deposits, notices, and repairs apply.
