ADUs
Overview
Accessory Dwelling Units (ADUs) are a type of dwelling unit that is located (inside or detached from a main home) on a single parcel of land or lot for the purpose of providing independent living facilities separate from the main home. They are commonly known as mother-in-law apartments, granny flats, basement apartments, garage apartments, etc. The goal of ADUs is to allow for more affordable housing opportunities for people at different stages of their life as well as allow for additional social or personal support for homeowners.
