This information is related to permit changes. The different types of permit changes are listed below, along with the steps to take to proceed with the change.​

Please contact the Planning Services Centre if you have any questions about application changes.

Revisions or revised plans​


Before approving an application, we ensure plans align with Calgary's Land Use Bylaw and/or National Building Code (Alberta Edition). If you make changes to your approved plan, your permit may not be valid, and you will need to submit the revised plans to us for review. For example, if the floor layout changes after approval, the parking requirements might change. This includes situations where changes occur on-site during construction.

​​

Please note, your application may require additional fees depending on the status of your permit and scope of your change. After we review your submission, we’ll contact you for payment of additional fees, if applicable. For more information, review our building and trade permit fee schedule.

Some changes may require Land Use Bylaw approval before you can submit a building permit revision. Land use approval may be required in the form of a revised plan or new development permit. Please contact your development permit file manager if you’re uncertain whether you require a Revised Plan application.
