What are the different types of ADUs that can be built?
Depending on the location and the project's specifics, several types of accessory dwelling units can be built. Some common types of ADUs include attached, detached, basement, attic or garage conversion, junior ADU, or SB-9.
1. Detached ADUs are standalone structures on the same property as a single-family home. Detached ADUs can be built in various styles and sizes and located in the rear yard or on the side of the property.
2. Attached ADUs are attached to the primary residence, like a home addition or a converted garage. Connected ADUs can be built in a variety of styles and sizes. They can be located on the first or second floor of the primary residence.
3. Basement ADUs are located in the primary residence's basement. Basement ADUs can be built in a variety of styles and sizes. They can be accessed through a separate entrance or through the primary residence.
4. Junior ADUs are small, self-contained living units, typically 400 square feet or less. They can be built as detached or attached structures and are often used as rental units or as extra living space for family or guests.
5. Converted ADUs are buildings converted from an existing space, such as a garage, a basement, or an attic. They can be used as rental units to generate extra income or as additional living quarters.
