An ADU (Accessory Dwelling Unit) is a small, self‑contained home on the same lot as an existing primary residence. Also called backyard homes, in‑law suites, casitas, or granny flats, ADUs include a kitchen, bathroom, living space, storage, and a dedicated entrance. In California, ADUs are permanent residences, not mobile “tiny homes”, and they’re designed to provide flexible, long‑term housing for family, guests, or tenants.
