Permits and Inspections

The Calgary Fire Department is the authority in Calgary for the installation, removal or alteration of all tanks that contain Class I, II and IIIA flammable and combustible liquids.

These requirements also apply to tanks that contain windshield washer antifreeze, that has been classified as a Class 1C flammable liquid.

You can learn more about liquid classifications in the National Fire Code - Alberta Edition. Please refer to Division B, Part Four: "Only individuals approved by the Provincial Fire Administrator are permitted to install, remove, repair or maintain storage tank systems".

To report a leak of 200 litres or more, call 9-1-1

If you have a tank system that isn’t registered with The City of Calgary, or if you have any questions about the correct permits and applications for your tank, please email tanks@calgary.ca.

When are permits required?

This includes outside aboveground storage tanks (AST), underground storage tanks (UST), inside building storage tanks (BST) and waste-oil storage tanks (WST).

How soon do I need a permit?
