As a homeowner, you’ve heard enough names for accessory dwelling units (ADU, in-law suite, casita, granny flat, etc.) If that’s the case, then you’ve probably heard about JADU. But what exactly is a JADU, and how are they any different or similar from the rest?

What’s a JADU?
Although both have some differences, a Junior Accessory Unit (JADU) is essentially a smaller version of the typical ADU. And, according to California state bills AB-68 and AB-881, both an ADU and a JADU can be built on the same property, which means you can add two rental units if you’re looking to expand your home.
However, according to Section 65852.22. Section A, owner-occupancy is actually required for the JADU. A clause in the section specifically states that JADUs require owner-occupancy in the single-family residence in which the junior accessory dwelling unit will be permitted. This means the homeowner may reside either in the remaining portion of the structure or the newly created junior accessory dwelling unit. Keep this in mind when you’re planning to do some major remodeling with your home.
JADU Specifications
- Size – 500 square feet (sq. ft.) max. This is smaller compared to a typical ADU, which is up to 1,200 sq. ft. or 50% of your living area.
- Location – It must be within a proposed or existing single-family dwelling or accessory structure, such as a detached garage or carport.
- Expansion – It may include an expansion of up to 150 sq. ft. beyond the footprint of the existing accessory structure, but it can be limited to accommodating ingress and egress.
- Separate Entry – This means a separate and exterior entrance for the JADU is required.
- Bathroom – Your JADU can have a separate bathroom or shared with the single-family dwelling.
- Kitchen – The kitchen of your JADU must meet “Efficiency Kitchen” requirements, which are:
- The required kitchen sink (16 inch by 16 inch max.) should have a small drain line (1.5 inches in diameter max.)
- No appliances that require natural or propane gas
- A food preparation counter and storage cabinets that are of reasonable size in relation to the size of the JADU
- Appliances that don’t require electrical service greater than 120 volts
