Do I need a permit to develop my basement in Calgary?
In most cases, yes. The City of Calgary requires a building permit when a basement is developed for the first time, and for changes like moving walls or adding windows and doors. Electrical and plumbing work need their own permits. Cosmetic updates like paint and finishes to an already-developed basement usually don’t. A development permit (planning approval) is only needed when your design doesn’t meet the Land Use Bylaw. We confirm what applies to your home during your free quote.

Legal Basement Suite Permits in Calgary
A legal basement suite is a secondary suite that has been permitted and inspected to meet Alberta safety codes. A basement with a full kitchen and bathroom counts as a secondary suite, so it needs the suite permits. A wet bar is allowed, as long as it has no cooking equipment.
What the City looks for:
- A self-contained suite with its own kitchen, bathroom, sleeping and living areas, and a private entrance
- Smoke-tight separation from the main home, interconnected smoke and carbon monoxide alarms, and soundproofing
- At least one exit directly outside, and egress windows in each bedroom
