Junior accessory dwelling units.

Assembly Member Carrillo's junior accessory dwelling unit legislation modifies California's owner-occupancy requirements for these small residential units, applying them only when sanitation facilities are shared with the main residence. The measure exempts properties owned by government agencies, land trusts, and housing organizations from this requirement, regardless of bathroom arrangements.

The bill establishes specific parameters for junior accessory dwelling units (JADUs), permitting one unit per single-family residential lot. These units must be constructed within the walls of an existing or proposed residence, including attached spaces like garages. Each JADU requires a separate entrance from the main dwelling and an efficiency kitchen with cooking appliances and appropriately sized counter and storage space. The legislation also institutes a minimum rental period exceeding 30 days for all JADUs.

Local agencies implementing JADU ordinances must require property owners to record deed restrictions that prevent separate sale of the units and maintain compliance with size and attribute requirements. While the bill creates new administrative duties for local governments, it specifies that municipalities may levy fees and assessments to cover implementation costs without state reimbursement.
