Building Permits

You are here

The property owner is responsible to ensure that a permit is obtained before work starts or the use of a building is changed and that all required inspections have been completed and approved before continuing with the next stage of work or occupying the building. By reviewing and approving building plans before any work is done, we can ensure that proposed work complies with the Ontario Building Code, the Zoning By-law, the Pool Enclosure By-law and other applicable laws.

Building permit videos

The Town has two new videos on its YouTube channel about building permits. Check them out - they tell you everything you need to know. 

What do I need for a permit?

Generally, a permit application can be made with 2 copies of a detailed site plan, 2 copies of complete construction drawings and specifications and permit fees.

Your application will be subject to the Town's Zoning By-law. Your first step will be to find out the zoning provisions for your property.

How to Use the Zoning By-law

There may be a number of other Town approvals such as:

  • permits to connect to Town water and sewer,
  • entrance permits (for access from the street),
  • lot grading permits, etc.

Approvals may also be required from external authorities such as:

  • Lake Simcoe Region Conservation Authority,
  • Ministry of Transportation,
  • Ministry of the Environment, etc.

Confirmation of compliance with all applicable law may not be required at the time of application but will affect the time it takes to review the application. All applicable law must be in compliance before a permit can be issued. A checklist will be prepared when outlining the outstanding requirements, if any, for permit issuance.
