Compiled from City of Calgary building-permit records (first-party permit record). CanPermits surfaces public permit records only and does not verify identity, licensing, or other business credentials.

This record covers building, electrical, gas, plumbing, mechanical, development, and tenancy-change permits the City of Calgary publishes openly. Many jobs need no permit at all — so a real track record is almost always larger than what appears here. Absence of records is not absence of activity.
