What is ADU?
An accessory dwelling unit (ADU) is a legal term for a secondary house that shares the building lot of a larger, primary house.
An additional residential building that occupies the same lot as a primary residence.
The establishment and use of an ADU will fall under different zoning rules and regulations depending on where you live.
An ADU has its own kitchen, living area, and a separate entrance.
