A basement suite is legal in Calgary when it has the right permits, meets the Alberta Building Code for things like smoke and carbon monoxide alarms, fire separation and exits, and passes the City's inspections. Alliance Renovations builds legal basement suites, with the kitchen, bathroom and safety work done by one company.
A suite is a home inside a home, so it needs more than a kitchen. The safety items are what the inspectors look for, and they are much easier to build in from the start than to add later.
Alliance plans the suite, builds it, and tracks the schedule, documents and payments in a Buildertrend portal you can check from your phone.
A legal suite starts with plans and permits, then the build, then the inspections.

The City of Calgary's requirements for secondary suites, with the City page for each one.
"As of Aug. 4, secondary basement suites became a permitted use, meaning applications are approved if the property meets applicable zoning, building, fire and safety requirements."

Source: City of Calgary, New secondary suiteNew suites "require an independent heating and ventilation system," with independent ductwork. The City's page for existing suites says one shared system is acceptable under the Alberta Fire Code.
Source: City of Calgary, New secondary suiteThese are the City of Calgary's rules as of October 2026. The City says its pages are a guide, not a legal reading of the bylaws. Since August 4, 2026 a property can have a secondary suite or a backyard suite, not both. The cities, towns and counties around Calgary have their own rules, covered on each area page.

“Highly recommend. Of all the companies that i contacted, Alliance was the only one that was able to construct a garage during the winter. They have done a beautiful job, on time and made the process painless. Colin, Ryan, Tim and the crew were amazing.

Every quadrant of the city, plus the communities around it.
The plans and the permit applications are part of the project. A legal suite in Calgary needs the right permits and passes inspections before it is finished, so Alliance starts with professionally done plans and builds to them. Ask Malachy to walk you through the steps on your assessment.
Not always. The ceiling height, the windows, a separate entrance and the space for fire separation all matter, and so does what the City allows for your property. Alliance checks these on a free assessment and tells you plainly if your basement can work.
Yes. Alliance offers project financing through Financeit, with a payment calculator and promotions that change through the year. Ask Malachy about current options when you book your free quote and assessment, so the plan fits your budget before any work starts.
Every Alliance client gets a Buildertrend project portal with the schedule, documents and payment tracking on your phone. Ebin called the tracking system a feature that truly sets Alliance apart, and customers like Gus say the team usually replies to messages within minutes.
