What is an ADU?

This is shorthand for an “accessory dwelling unit” sometimes referred to as a “granny flat,” “in-law unit” or “backyard cottage.” There are also JADUs or “junior accessory dwelling units.” Both ADUs and JADUs are additional independent living facilities, for one or more persons, which are located on the same parcel as a primary residence or residences. ADUs and JADUs are now permitted where residential uses are allowed, including single-family lots.
