A secondary suite is defined in the City of Abbotsford Zoning Bylaw as a Dwelling Unit that is Accessory to, and within, a principal Dwelling Unit, and is part of the same real estate entity. A secondary suite is a portion of a single detached home which is established as a separate dwelling unit from the principal part of the house. It is typically a finished basement with cooking facilities, a separate entrance from the exterior, and has a lockable, fire-rated door between it and the remainder of the principal dwelling.
Secondary suites are required to be registered with the City. Registration confirms that suites comply with the BC Building Code and Abbotsford Zoning Bylaw, 2014. A number of legal, health, life safety, fire protection, and zoning requirements must be met for the suites to be registered.
