Accessory suites are self-contained dwelling units that are secondary to a main dwelling on a lot. This includes both secondary suites and backyard suites.
All accessory suites must meet land use bylaw regulations and require both a development permit and a building permit before they can be occupied.
Types of accessory suites
Secondary suites
Secondary suites are self-contained dwellings located within a single detached or semi-detached dwelling.
Backyard suites
Backyard suites are detached, self-contained dwellings located on residential lots with a single detached dwelling. They may be stand-alone buildings or located above or attached to an accessory building such as a garage.
Regulations and guidelines
Accessory suites must comply with the land use bylaw. View the Town of Cochrane Accessory Suite Guidelines (PDF) to understand zoning requirements and regulations.
Building permits and inspections
In addition to a development permit, accessory suites must meet requirements under the Safety Codes Act and applicable building, electrical, plumbing and gas codes. Visit building permits and inspections for more information.
