The bill amends the Residential Landlord-Tenant Act in Washington State to address the use of smart access systems in residential properties. It introduces new definitions such as "smart access building" and "smart access system," which refer to buildings that utilize electronic technology for entry. Landlords are mandated to provide tenants with alternative access methods that do not rely on biometric data or mobile applications, such as key fobs or physical keys. Additionally, landlords must disclose written privacy policies regarding the smart access systems, detailing the data collected, retention schedules, and protocols for data protection and unauthorized access.

The bill also establishes guidelines for the collection and use of data by landlords and third parties in smart access buildings. It specifies that landlords may only collect the minimum necessary authentication and reference data for access purposes, including a user's name, dwelling unit number, and other relevant information. If landlords do not retain or sell any information from the smart access system, they can comply with privacy requirements by providing the privacy policy of the smart access system developer. Overall, the bill aims to enhance tenant rights and privacy while ensuring effective management of access to residential properties.
