This bill establishes a new chapter in Title 19 RCW concerning the confirmation of property ownership or owner authorization for short-term rentals in Washington State. It defines key terms related to short-term rentals, including "dwelling unit," "operator," "owner," and "short-term rental." A "short-term rental" is specifically defined as a lodging use for fewer than 30 consecutive nights, excluding licensed hotels, motels, and certain charitable organizations. The bill clarifies that individuals who lease a property are not considered owners and outlines the responsibilities of short-term rental operators.

Additionally, the bill mandates that short-term rental platforms require operators to confirm that they are either the owners of the dwelling unit or have authorization from the owner to offer the unit for short-term rental. This provision aims to ensure accountability and proper authorization in the short-term rental market. Overall, the legislation seeks to regulate short-term rentals more effectively by establishing clear definitions and requirements for operators and platforms.
