What is a Garden Suite or ADU?
A Garden Suite (or ADU) is a self-contained secondary home on your property. It can be a:
✔ Detached backyard home (garden suite)
✔ Garage conversion (above or within an existing structure)
✔ Basement apartment (in-law suite)
✔ Converted workshop or barn (rural ADU)
Why build one?
Independent living space for family (aging parents, grown children)
Rental income (long-term tenant or Airbnb potential)
Increase property value (high ROI for resale)
Flexible use (home office, guest suite, future downsizing option)
An Accessory Dwelling Unit (ADU) is a secondary housing unit on a single-family residential lot. ADUs can be separate structures or part of the main house and come in various forms, such as:
Detached New Construction
A completely separate structure on the same lot.
Attached Additions
An addition to the main house.
Garage Conversions
Transforming an existing garage into a living space.
Internal Conversions
Converting a part of the main house, such as a basement or attic.
Understanding SecondARY DWELLING Units
A secondary dwelling unit is a self-contained dwelling unit with a private kitchen, bathroom facilities, and sleeping areas. It can be located in your house or on your property, such as above a laneway garage or in a coach house. These units must meet specific Building Code requirements to ensure safety and functionality.
