What's the timeline for getting a secondary suite permit approved in Calgary? I've heard it's 6-8 weeks minimum?

Secondary suite permits in Calgary typically take 6-12 weeks for approval, with your 6-8 week estimate being on the optimistic side for most applications. The timeline depends on whether you're adding a new secondary suite or legalizing an existing one, plus the complexity of your specific situation.

The City of Calgary requires a development permit for secondary suites, which you apply for through the online portal at calgaryplanningpermit.ca. Simple applications with no variances needed and compliant properties can move through in 6-8 weeks, but most homeowners should plan for 8-12 weeks. If your application requires variances (parking, setbacks, or other zoning relaxations), add another 4-8 weeks to the timeline.

Common delays include incomplete applications, missing documentation, or the need for additional information from your consultant. The City will put your application "on hold" until you provide what's needed, which stops the clock on processing time. Make sure your application includes detailed floor plans, site plans showing parking spaces, and confirmation that the suite meets all Alberta Building Code requirements for fire separation, egress windows, and ceiling heights.

Calgary's secondary suite requirements are straightforward but strict: separate entrance, minimum 1.95m (6'5") ceiling height throughout, egress windows in bedrooms, proper fire separation between units, and interconnected smoke alarms. You'll also need to demonstrate adequate parking - typically two spaces per dwelling unit, though some inner-city areas have relaxed parking requirements.

After development permit approval, you'll need building permits for any construction work (electrical, plumbing, structural modifications). These are separate applications that can run concurrently or after your development permit is approved. Electrical and plumbing permits are issued by accredited Safety Codes Officers under the Safety Codes Council of Alberta system, not directly by the City.

Pro tip: Hire a consultant experienced with Calgary secondary suite applications. They know exactly what the City wants to see and can help avoid the back-and-forth that extends timelines. The upfront cost of professional drawings and application preparation typically saves weeks of delays and revision requests.

Start your application as early as possible - don't wait until you're ready to start construction. You can begin the permit process while finalizing your renovation plans and contractor selection.
