The bill amends RCW 59.18.060 to enhance rental property disclosures regarding flooding history and flood risk. It mandates that landlords provide tenants with specific information about the potential for flooding, including whether the property is located in a special flood hazard area, that the landlord's insurance does not cover tenants' personal possessions, and that tenants should consider obtaining renter's and flood insurance. These disclosures are required for leases entered into after December 31, 2026. Additionally, the bill includes provisions for landlords to inform tenants about health hazards associated with indoor mold and requires them to provide a written notice detailing fire safety and protection information.

Furthermore, the bill establishes that landlords are immune from civil liability for failing to comply with the new disclosure requirements unless they knowingly and intentionally disregard them. It also reinforces existing responsibilities of landlords to maintain the premises in a habitable condition and outlines the procedures for reconnecting utility services during heat-related alerts. Overall, the legislation aims to improve tenant awareness of risks associated with flooding and enhance safety measures in rental properties.
