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, with additional detached ADUs being designated as restricted-affordable units on larger lots. The bill also sets size requirements 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 smaller. Furthermore, it prohibits counties from imposing certain restrictions on ADUs, such as requiring familial relationships between occupants or additional parking, and ensures that ADUs are subject to the same regulations as single-family homes.

Additionally, the bill removes the population threshold for municipalities regarding the adoption of regulations for single-family dwellings, making these regulations applicable universally. It clarifies exemptions for certain lands, including tribal land and areas near military airports, and introduces new definitions and requirements for ADUs. The bill also establishes compliance measures for vacation rentals, including emergency contact requirements and notification of adjacent properties, while imposing civil penalties for non-compliance. Overall, these updates aim to streamline the approval process for ADUs and enhance housing availability while addressing community concerns related to vacation rentals.
