What is an Accessory Dwelling Unit or ADU?

An Accessory Dwelling Unit (ADU) is a secondary living unit that is typically located on the same property as a primary residence. ADUs are also known as backyard homes, granny flats, Airbnb homes, in-law units, or secondary suites. They are self-contained living spaces with their own entrance, kitchen, bathroom, and sleeping area.

ADUs can be attached or detached from the primary residence and are designed to provide additional living space for family members, guests, or renters. ADUs are often smaller in size than the primary residence and can be used as a rental property, home office, airbnb home or guest house.

ADUs have become increasingly popular as a way to address the shortage of affordable housing and provide homeowners with additional income. Many cities and towns have zoning regulations that govern the construction and use of ADUs, so it is important to research local regulations before building an ADU.
