East Gwillimbury (EG) issues approval and building permits for accessory apartments. The process for Accessory Apartment additions is:

  1. Contact Planning to review the steps and requirements involved including enough parking spaces and sewer capacity.
  2. Check the zoning to ensure that a secondary unit/accessory apartment is allowed.
  3. Review the requirements for building permits and apply for a building permit.

Learn more about the fees and charges involved.

It is also recommended to review the Province's guide for adding a second unit for more information, including what is considered a second unit, requirements, and the process for adding one.
