ADU Accessory Dwelling Unit

ADU stands for Accessory Dwelling Unit and they might just be your next edited home. You might know ADUs by their other, quasi-affectionate names such as granny-flats, mother-in-law-apartments and so on. They are dwellings–either attached or detached from a main house–that exist on a lot with another house. Many ADUs are buit above garages such as the one pictured above.
