Apply for a building permit

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.

Residential building permits

You can use our online services tool to apply for residential building permits (for decks, additions, alterations, secondary suites, new builds), as well as permits for demolition, signage, septic or pool/spa enclosures.

Industrial, commercial and institutional (ICI) building permits

Follow these steps to start the ICI building permit process:

  • Send us an email with the project address, then we will send you a ShareFile link.
  • Upload your completed permit package to the ShareFile link provided.
  • Staff will contact you within two business days to discuss your permit application.

Guidelines for building permit applications

All building permit submissions 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.

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, you will receive notification with an invoice for permit fees, including payment options. Permit fees are due upon receipt to begin the full 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 requires files to be submitted according the following requirements:

  • 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.
