California ADU Law Updates Effective January 1, 2026 Several amendments to California’s Accessory Dwelling Unit (ADU) and Junior Accessory Dwelling Unit (JADU) statutes took effect on January 1, 2026. The principal measures are Senate Bill 543, Assembly Bill 1154, and updates to the previously approved Senate Bill 9. Assembly Bill 462 was enacted as an urgency statute and became effective October 10, 2025. These changes refine definitions, clarify procedural timelines, expand fee limitations, adjust JADU occupancy rules, and strengthen state oversight of local ordinances.

California’s 2026 ADU updates are now in effect including new completeness timelines, clarified size standards, fee limitations, JADU occupancy changes, coastal permitting rules, and strengthened HCD oversight. Read the full article: https://wp.me/p2M8ej-1MF #CaliforniaADU #Architecture #SB543
