Accessory Apartments

The New Accessory Apartment Registry System
By-law 98-33

The Town of East Gwillimbury permits one accessory apartment in single detached and semi-detached residential units, provided certain criteria, such as sufficient parking spaces and municipal servicing, are satisfied. In order to understand all applicable regulations and policies, it is very important that you consult with the Town prior to establishing an accessory apartment.

Council's Action
In response to Provincial legislative changes, Town Council has implemented an accessory apartment registry system for East Gwillimbury. 

The registration by-law prohibits the use or occupancy of a second unit in a house unless the house is registered pursuant to the by-law.  The provisions of the registration by-law give the municipality the authority to refuse to register a two-unit house if the house does not comply with the by-law standards or if required infrastructure is not available.  The Town may also revoke a registration where the house has ceased to comply with these standards. 

The registration system assists the Town of East Gwillimbury and its residents by ensuring that all dwelling units in the Town, both existing and proposed, meet health, safety and zoning requirements under the Building Code, Fire Code, Zoning By-law and Property Standards By-law. 

Landowners who register their two-unit houses benefit from being able to demonstrate to prospective tenants, purchasers, insurance companies, mortgagees, etc. that the house has been registered with the Town and may therefore be lawfully occupied.  The registry system provides quick, accurate information summarizing inspections completed for a specific apartment located on a property.  Likewise, it provides statistics that can be used by the Town when studying the impacts of accessory apartments in certain communities.  In addition, the registration of a two-unit house provides critical information to emergency services trying to locate an apartment contained in the house. 

Fees for the registration of a two-unit house are as follows:


Total Fee:  $1,350.00 as follows:
Upon application (non-refundable)  $675.00 per two-unit house
Prior to approval of registration (if granted)  $675.00 per two-unit house

The required registration fee is a one-time, non-refundable fee.  However, if at anytime, there is non-compliance with the registration by-law, registration can be revoked and payment of a fee will be required to re-register the house.  If the registration of a two-unit house is revoked, the Owner of the two-unit house will be notified of the revocation by registered mail, and provided with a brief explanation of the reason for the revocation.

Every person who contravenes any of the provisions of the registration by-law is guilty of an offence and, upon conviction, is liable to a fine as provided for in the Provincial Offences Act.

All information required to fulfil the requirements for registration (e.g. approval from an external agency, i.e. Electrical Safety Authority) must be obtained by the applicant.  Any agency may charge a separate fee required for the review and issuance of a permit or approval.  A copy of the application for registration of a two-unit house is available at the Holland Landing Fire Station, 19314 Yonge Street, Holland Landing.
