The proposed bill would update current statutes by mandating that counties allow at least one attached and one detached accessory dwelling unit (ADU) on lots designated for single-family dwellings. For larger lots exceeding one acre that include at least one restricted-affordable unit, the bill requires the allowance of an additional detached ADU. It also sets size limitations for ADUs, capping them at 1,000 square feet or 75% of the primary dwelling's gross floor area, whichever is smaller. Furthermore, the bill prohibits counties from imposing certain restrictions on ADUs, such as requiring a preexisting relationship between occupants or additional parking, and establishes an automatic allowance for ADUs on all residentially zoned lots if counties do not comply by January 1, 2026.

In addition to the provisions for ADUs, the bill introduces new regulations for vacation rentals, including requirements for owners to provide emergency contact information and display permit numbers in advertisements. It outlines penalties for non-compliance and the notification process for adjacent properties prior to renting. The bill also clarifies exemptions for areas near military or public airports with high noise levels. Overall, these updates aim to streamline the approval process for ADUs and enhance the regulation of vacation rentals while ensuring adherence to local zoning laws.
