What are ‘ADU’s and ‘JADU’s?

According to the California Department of Housing and Community Development, Accessory Dwelling Units (ADUs) have been known by many names: granny flats, in-law units, backyard cottages, secondary units and more. They are secondary units built on the same property as the existing home. 

The Difference between an ‘ADU’ and ‘JADU’?

ADU’s are detached structures, meaning they are located on the same property but do not exist within the walls of the existing structure. This is typically what you think of when you think of ‘ADU’. A detached garage or granny flat in the backyard would be considered ‘ADU’s’. 

JADU’s on the other hand – do exist within the walls of an existing single-family residence. They may share central systems and do have to contain basic necessities like a kitchen and place to sleep. They can share an existing bathroom and will contain no more than 500 square feet.
