Depending on the project, you may need a demolition permit. If you are demolishing or moving a building, including partial demolition such as keeping the foundation and removing the building, you’ll need a permit issued by the City of Calgary. For interior commercial demolition or interior residential demolition in Calgary, you’ll require a building permit rather than a demolition permit. These procedures allow the city to be aware of the project, arrange for water, gas, or power to be disconnected to the building, and allow for inspections by city officials.
