Residential Building Permits

Building permits give legal permission to construct, demolish or renovate on a property. Constructing without the benefit of a building permit may result in construction delays and the removal of work completed. The checklists below are guides to assist in better understanding the requirements for submitting a complete building permit application. You may also refer to the Municipal Building By-law which provides detailed operational and procedural requirements and also includes a detailed building permit fee schedule.

Building Services will provide a secure Share File link to upload your documents and files.  Submit permit applications and files using our secure SHARE FILE system.

Permit Submission:

When a permit submission is received by Building Services, a permit file name is created.  Building Services Staff will review for a complete application.  An email will be sent to the applicant acknowledging the submission and providing the building permit file number, which is to be used for all future correspondence.  This will be followed by an email after permit review (see below) stating any outstanding documents if the submission is not deemed to be complete. 

Permit Review:

Once the Plans Examiner has completed review of the permit submission, building permit fees, any concerns or outstanding information required will be sent to the applicant via email.

Permit Issuance:

After approval and payment of fees for an electronically submitted application and issuance of the permit by Building Services, you will receive your Reviewed Drawing Set electronically via email.  Please print a set of all approved drawings or specifications (in colour) and ensure this reviewed drawing set is available to the inspector on-site for every inspection.  

Site Revisions: 

Where a submission is being made to address a deficiency identified by a Building Inspector/Examiner, an electronic copy of the revised plans shall be submitted with the changes clearly labelled with revisions noted.  A fee for revisions may be applicable as per Building By-Law #2014-18.
