What is an ADU?
An ADU, or Additional Dwelling Unit, is a small, separate living space on the same property as your main home, which can either be a detached unit in your backyard, an attached extension to your house, or a conversion of an existing space like a garage or basement. If you’re considering building an accessory dwelling unit, it’s essential to review various accessory dwelling unit plans and accessory dwelling unit designs. Proper planning and thoughtful accessory dwelling unit construction are crucial to creating a comfortable and functional space.

Types of Additional Dwelling Units (ADUs) You Can Build
DETACHED ADUs (Garden Suites or Laneway Houses): These are standalone structures built on the same lot as the main residence, but not attached to the main house. They are typically constructed in the backyard and are fully self-contained, with their own entrance, kitchen, bathroom, and living areas.
ATTACHED ADUs: An attached ADU is an additional unit that is physically connected to the main house, often through an extension or addition. It may share walls with the primary dwelling but will have a separate entrance and facilities like a kitchen and bathroom.
INTERIOR ADUs (Basement Apartments or Secondary Suites): Interior ADUs are created within the existing structure of the main house, such as a finished basement or a portion of the house that has been converted into a separate living unit. These are common in areas where space is limited but additional housing is needed.
GARAGE CONVERSION ADUs: This type of ADU involves converting an existing garage, either attached or detached, into a livable space. It is a cost-effective way to add housing since the structure is already built, and it can be transformed into a functional apartment with minimal modifications.
ABOVE-GARAGE ADUs: If you have a garage, you can build an ADU on top of it, creating a small apartment above the parking space. This type of unit is often seen in urban areas and can offer a great way to maximize the use of your property.
