How large can my ADU be?

According to state law, most ADUs can be at least 800 square feet, as long as rear and side setbacks are at least 4 feet and it is not above 16 feet tall. Otherwise, size limits depend on your property. No room behind or next to your main home? You can build it in your front yard instead.
