What is JADU?

A Junior Accessory Dwelling Unit, also known as JADU, is a small independent living space created by converting some space in your single-family residence into a separate housing unit through adding a small kitchen and a separate exterior entrance.

What makes a jadu?

Here are some characteristics of JADUs:

  • Size: 500 Sq. ft. max
  • Location: within an existing (or proposed) single family dwelling, such as an extra bedroom or garage. Please note that the garage must be attached to the house to qualify for JADU conversion.
  • Access: separate exterior entry
  • Bathroom: may have separate or share with the single-family dwelling
  • Kitchen: should meet requirements for “efficiency kitchen”: include food storage and preparation area with a sink, cooking appliances, a refrigerator, and a clear working space in front of each that must be 30 inches minimum.
  • Parking: not required. In case of garage conversion, parking must be replaced unless the property is within 0.5 mile from public transportations.
  • Leasing: Legally rentable, but owner occupancy is required (only applies to JADUs, and not ADUs)

Request a free consultation to see if your property qualifies for building a JADU in addition to anADUs. ADUs are increasing in popularity

What are the differences between jadu and adu?

JADUs are smaller in size relative to the ADUs, and have fewer requirements to be met for permits and construction. For example, ADUs in LA county can be up to 1,200 sq. ft. in size, whereas JADUs cannot be bigger than 500 sq. ft.. Also, JADUs have fewer kitchen requirements that need to be met for construction.

The great news is that you don’t have to choose between the 2! You can build a JADU in addition to a detached ADU on your property. They only thing to keep in mind is that JADUs must be attached to the existing building on your property, and your residence must be owner-occupied to rent out the JADU.
