Before any construction of a new building or renovation can begin, you will need to obtain a building permit. Whether you are finishing your basement, adding windows or doors or constructing a deckfence or pool, you’ll need a building permit. Building without a permit can result in fines and penalties as set out in the Building Code Act.

Apply for a permit

A building permit submission shall include a completed Building Permit Application that includes all drawings and additional forms required as noted below in the Application Guidelines. The application and necessary drawings and forms are required to be submitted in PDF format electronically to the building permit email.

The application will undergo an initial cursory review to determine completeness, with applicants being advised via email regarding status of the application’s acceptance or refusal. If your submission is refused, we will email you as to the reasons why, and the necessary corrections required to revise and resubmit accordingly, to complete the submission.

Once the building permit application package has been accepted, we will email you the invoice for permit fees, including payment options. Permit fees are due upon receipt to begin the permit review. If necessary, you will be notified by email if we require additional information to review and complete your permit application. We will also notify you by email when your building permit has been issued along with all supporting documents.

Digital submission requirements

The Town of Milton is currently utilizing electronic plans review software and is requiring digital submissions of any plans submitted with building permit applications to be emailed to Building Permit staff.


  • Digital files must be in .pdf format and generated directly from the software used to create them (AutoCAD, Softplan, Revit, etc.) using a PDF printer or converter (no scanned copies)
  • All .pdf files must have the document properties/restrictions/security settings/permissions set to allow "Printing" and "Adding Markups" so staff can apply redline notes and approval stamps to the documents

If you would like to send files electronically that are larger than 10mb, please contact us to request a secure file link to accommodate larger file requirements.
