What is an ADU?

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 Second Units

A second 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.

The Purpose of ADUs

ADUs are becoming increasingly popular due to their versatility and the benefits they offer. They provide additional living space for extended family, generate rental income, and increase property value. ADUs also contribute to addressing housing shortages and promoting sustainable urban growth.
