Junior Accessory Dwelling Unit JADU
A Junior Accessory Dwelling Unit (JADU) is a compact living unit created entirely within the existing footprint of a single-family home. JADUs provide a practical and cost-efficient way to add independent living space without additions or new construction.
This ADU type is specifically designed for homeowners who want to maximize interior space while maintaining close connection to the primary residence.
[01 Definition]
What is a JADU?
A JADU is a small accessory dwelling unit, typically up to 500 square feet, created within an existing single-family home. It may be carved out of existing rooms or repurposed space and includes a dedicated sleeping area, living space, and efficiency kitchen.
Unlike other ADU types, JADUs are regulated separately and come with specific requirements related to size, ownership, and occupancy.
Housing for Family Members
JADUs are often used to house extended family members, providing privacy while keeping occupants close to the main household.
