What is a JADU?

Under California state law, homeowners can now build both an ADU and a JADU on their property.

You may have heard of a JADU or Junior Accessory Dwelling Unit. Put simply, a JADU is a smaller version of an ADU.

JADUs follow the following guidelines - some of which differ from an ordinary ADU:

  • Located within existing walls of the primary home, including within the attached garage

  • Owner occupies rest of house

  • Maximum size 500 square feet

  • Separate exterior entrance

  • Efficiency kitchen: sink, cooking appliance, counter surface, and storage

  • May share a bathroom with primary residence—if so, needs a direct entrance into the main living space of the primary dwelling

For homeowners who are looking to maximize rental income, adding a JADU in addition to an ADU might be an excellent option.
