AB 1482 reshapes how California homeowners manage ADU rentals, introducing rent caps and just-cause eviction rules. While many ADUs qualify for exemptions like the 15-year new construction rule or single-family ownership, local ordinances in cities like Los Angeles, San Francisco, and Oakland can override state protections with stricter regulations. Understanding exemption timelines, ownership structures, and required legal notices is critical before leasing your ADU. A proactive approach ensures compliance, protects your rental income, and avoids costly legal issues.
