The proposed bill would update current statutes by mandating that counties allow accessory dwelling units (ADUs) on any lot where single-family dwellings are permitted. Specifically, it would require counties to permit at least one attached and one detached ADU, and for lots of one acre or more, at least one additional detached ADU, which may be a restricted-affordable unit. The bill also sets size limitations for ADUs, stipulating that they must be at least 75% of the gross floor area of the primary dwelling or 1,000 square feet, whichever is less. Additionally, it prohibits counties from imposing certain restrictions on ADUs, such as requiring familial relationships between occupants or additional parking, and clarifies that counties cannot condition ADU permits on the adoption of restrictive covenants.

Furthermore, the bill modifies existing regulations related to vacation rentals, including the requirement for owners to provide emergency contact information and conditions for residency on properties with ADUs. It introduces civil penalties for non-compliance and clarifies definitions related to ADUs and vacation rentals. If counties do not adopt the required regulations by January 1, 2026, ADUs will be allowed on all residentially zoned lots without restrictions. Overall, the bill aims to streamline the approval process for ADUs and enhance the regulatory framework for vacation rentals while ensuring compliance with local and state laws.
