What is a junior ADU?

A unit of up to 500 square feet inside a single-family home, which can include an attached garage. It needs an efficiency kitchen and a separate entrance. The bathroom can be its own or shared with the main home.

Why choose one?

It is usually the least expensive way to add a unit, because the walls, roof and most utilities already exist.

What are the limits?

Rentals must be longer than 30 days. If the JADU shares bathroom facilities with the main house, a city can require the owner to live on site.
