In 2018 Council passed by-law 108-18 to allow a secondary dwelling unit on residential single detached, semi-detached and linear row house properties in the City of Cambridge with specific requirements for lot area, frontage and parking.

In 2019 further changes to the Planning Act through Bill 108 were put in place requiring municipalities to revise accessory dwelling unit regulations and allow for an accessory unit in the principle building and an accessory unit in an ancillary building for a total of three residential dwellings on one property.

The City has initiated a review of the accessory residential unit regulations to assess the effectiveness of the existing regulations and establish new regulations to meet the requirements of the Planning Act for 3rd units.
