dwelling units in accordance with Section 16(3) of the Planning Act. The policies are structured to describe what constitutes an ADU, where they are permitted, and how they should be constructed. These policies are largely amendments to second unit policies introduced under OPA 122 [OPA/5538] and Z-009/18 [ZNG/5571] (Council Report: S 102/2018). The OPA document is attached as Appendix A. The following summarizes and explains the policy direction.

What:

• Separate residential dwelling units that have separate access, kitchen, washroom, and living space.

Where:

• Permitted in residential areas within single detached, semi-detached, and townhome/rowhouse dwellings and within buildings accessory to these dwelling types (e.g. additional unit above detached garage). See Appendix C for a map of residential areas.

• Within floodplain areas — ADUs are not permitted within basements. See Appendix C for a map of areas regulated by the Essex Region Conservation Authority (ERCA).

• Outside of floodplain areas—basement units may be permitted where flood mitigation criteria has been met to the satisfaction of the Chief Building Official or City Engineer.

How:

• Must be smaller in area than 100 m2.

• Parking can be accommodated where required (e.g. core areas well served by transit and with smaller properties would not be required to provide parking).

• Zoning bylaw can regulate height, size, setbacks and other elements of ADUs.

• Must not alter building exterior of heritage properties that is visible from the street.

• Building permit is required.

• Units in accessory buildings must have direct pedestrian access from the street or alley (i.e. tenants must not be required to access the additional unit through the primary unit).

• Units in accessory buildings must have access to a paved public street, municipal sanitary sewer, municipal storm water outlet, electrical, and water services.

• There is a prohibition on the severance of additional residential
