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 applicable Emergency Services and Building fees by visiting our fees and charges page. 

All accessory apartment applications require a Fire Department review to ensure compliance with applicable fire safety requirements. A Fire Department review fee will be charged at time of application in addition to all applicable building permit fees. Please note that 50% of the Fire accessory registration fee is non-refundable. 

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.
