Additional Dwelling Units (ADUs)

The Government of Ontario passed Bill 23, the More Homes Built Faster Act, on November 28, 2022. This Bill  made a variety of changes to different Acts, including several changes to the Planning Act

As a result of these changes, the City's previous 'Secondary Dwelling Unit' policies were amended for new 'Additional Dwelling Unit (ADU)' policies. These policy changes came into effect in April of 2023. 

In order to assist property owners with the construction of a new Additional Dwelling Unit (ADU), or going through the process to recognize an existing Additional Dwelling Unit (ADU), the City has prepared some Frequently Asked Questions (FAQs) and a process document to help provide information and explanations about the requirements.

A copy of the Office Consolidation of the City's Zoning By-law 2015-30 is available here.
