What is an Accessory Dwelling Unit?

An accessory dwelling unit (ADU), also known as a “mother-in-law” or “granny flat,” is a smaller home with complete independent living facilities on the same parcel as a "primary" home.  ADUs can take many forms and vary in size but always contain everything someone needs to live, including a kitchen, bathroom and a place to sleep.  ADUs typically range in size from 220 square foot studios to 1200 square foot units with multiple bedrooms.
