A Junior Accessory Dwelling Unit (JADU) means a complete independent living facility that is no more than 500 sqft in size and contained entirely within an existing or proposed single family home (think garage or spare bedroom). A JADU must have a separate exterior access, as well as a full bathroom and efficiency kitchen. The kitchen must have a cooking facility with appliances and a food preparation counter and storage cabinets that are of reasonable size in relation to the size of the JADU.
