What is an Accessory Dwelling Unit?
An Accessory Dwelling Unit (ADU), also called a second unit, a junior accessory dwelling unit (JADU), granny flat, in-law unit, or backyard cottage, is an additional unit of housing added to a parcel of land containing a single-family home. ADUs can be attached to the main home by converting an extra bedroom, garage or basement, or built as an addition, or they can be completely detached if there is enough space on the lot. ADUs have the potential to yield multiple benefits for residents and communities:
- New, more affordable homes for smaller households within the fabric of existing neighborhoods
- Flexible living spaces that meet the needs of families that are branching, blending and aging
- Supplemental income for homeowners seeking financial stability
- Housing solutions for specific populations, including formerly homeless, seniors, home healthcare workers, developmentally disabled adults, and teachers
- Reduced traffic congestion resulting from increased housing supply near public transit
- Local construction jobs and training opportunities
