Accessory suites

Take the accessory suites survey until April 15

In June 2023, Council approved the Affordable Housing Action Plan and tasked City staff to revisit the rules around accessory suites (secondary, garden and garage suites). The goal? To remove obstacles when building approved suites, recognizing their potential to boost our local economy and champion sustainable growth. 

An accessory suite is a secondary dwelling from the principal residence and can be a garage suite, a garden suite or a secondary suite.
