The proposed bill would significantly 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, with additional provisions for larger lots, including the potential for a restricted-affordable unit. The bill also sets a minimum size for ADUs and introduces prohibitions against certain county regulations, such as requiring familial relationships between occupants or additional parking. If counties do not comply by January 1, 2026, ADUs would be allowed on all residentially zoned lots without restrictions.

Additionally, the bill removes the population threshold for municipalities regarding single-family dwelling regulations, thereby applying these rules universally. It clarifies existing regulations for vacation rentals, including emergency contact requirements and residency conditions for property owners with ADUs. The bill also establishes penalties for non-compliance and ensures that counties cannot impose more restrictive regulations on ADUs compared to single-family dwellings. Overall, the bill aims to streamline the approval process for ADUs and enhance the regulatory framework for vacation rentals while maintaining public safety and zoning compliance.
