The proposed bill establishes statewide standards for local governments in Washington regarding the enforcement of laws that regulate the use of public spaces for life-sustaining activities, particularly in the context of homelessness. It prohibits cities, towns, and counties from enforcing laws that criminalize or penalize life-sustaining activities on public property unless they can demonstrate that sufficient shelter space was available at the time of the conduct. The bill allows individuals to defend against citations by proving their actions were necessary and that no adequate shelter was available. It also outlines the definition of "adequate alternative shelter space" and includes provisions for local governments to adopt policies for verifying shelter availability and coordinating with service providers.

Additionally, the bill establishes provisions regarding the enforcement of county laws related to homelessness and shelter availability, ensuring that a prevailing plaintiff in actions under this section is entitled to reasonable attorneys' fees and costs, while clarifying that plaintiffs are not liable for attorneys' fees unless the action is deemed frivolous. It emphasizes that the bill does not create a private right of action for monetary damages, except for specified attorneys' fees and costs, and applies retroactively to all causes of action and county laws existing on or after its effective date. The bill also details the responsibilities of counties in verifying shelter bed availability and allows for interlocal agreements to establish regional shelter capacity, ensuring that adequate alternative shelter space is accessible while protecting individuals' rights.
