CA SB477

Reorganizes and consolidates California's accessory dwelling unit (ADU) and junior accessory dwelling unit (JADU) laws into a new Chapter 13 of the Government Code, establishing clear standards for their creation and approval.

Establishes ministerial approval processes for ADUs and JADUs, requiring local agencies to approve applications within 60 days without discretionary review, with automatic approval if agencies miss the deadline.

Sets maximum standards for ADUs including size limits (1,200 square feet for detached units, 50% of primary dwelling for attached units), parking requirements (max one space per unit), and height allowances (up to 16-18 feet depending on location).

Voids covenants, restrictions, or conditions in property deeds and planned development documents that prohibit or unreasonably restrict ADU or JADU construction on single-family residential lots.

Makes nonsubstantive changes to housing element requirements, local approval processes, and related statutes to align them with the reorganized ADU provisions, and declares the act an urgency statute effective immediately.
