What are ADUs?

Additional Dwelling Units (ADUs) are secondary housing units located on the same property as a primary residence. They come in various forms, such as laneway houses, converted garages, standalone structures, or additions to existing homes.

Distinguishing Elements of an ADU:

  • A Dwelling Unit that contains its own bathroom, kitchen and living area.
  • Must be on the same lot as a Single Detached, Semi-Detached, and Townhouse.
  • Cannot be sold or severed to create a new lot.
  • Has its own entrance from rear, side, or in a common foyer or vestibule.

Types of ADUs:

Attached Dwelling Units to the Principal Structure

Examples of ADUs:

  • Laneway House: A laneway house is a form of detached secondary suites in Canada built into pre-existing lots, usually in the backyard and opening onto the back lane.
  • Coach House: A coach house is designed with the living area above a garage or a carport.
  • Garden Suite: Typically, garden suites are single or two story structures built in the back yards of single detached homes and must have their own kitchen, bathroom, and living space.
  • Tiny Home: Living in a tiny home on a foundation in Ontario is possible in any municipality that allows detached secondary dwellings in backyards of existing homes.

The Benefits of ADUs:

  1. Affordable Housing: ADUs provide an affordable housing solution for homeowners, renters, or multigenerational families by utilizing existing space without the need for extensive land development.
  2. Increased Property Value: These units can enhance property value by offering additional living space, which can attract potential buyers or provide rental income for homeowners.
  3. Flexible Living Arrangements: ADUs facilitate flexible living arrangements, allowing for multigenerational households, housing for caregivers, or rental opportunities to supplement income.
  4. Sustainable Urban Development: By utilizing underutilized space within established neighborhoods, ADUs support sustainable urban growth, maximizing land use without creating additional sprawl.

Due to site constraints, not all lots are suitable for ADUs. Contact us if you’re interested in an ADU and we will work with you to determine whether your lot is suitable, or which type of ADU would be best suited for your needs.
