A garden suite (also known as carriage house, coach house, granny flat and laneway house) is a smaller accessory dwelling unit within a detached accessory building on the same lot as the single family dwelling.  A garden suite may be one storey or above a detached garage (two storey).  A suite should contain a bathroom, a kitchen with cooking facilities and at least one bedroom. 

All Garden Suites require the completion of a Development Permit Application Form
