The proposed bill establishes a framework for creating animal services districts in Washington State, which will be responsible for providing essential services such as shelter, medical care, adoption services, pet licensing, temporary emergency housing, and humane law enforcement. The formation of these districts can be initiated through a citizen petition or local government resolution, followed by a ballot proposition that must be approved by a majority of voters in the proposed district area. The bill also outlines the governance structure, allowing for the election of a board of animal services commissioners or the appointment of existing city or county officials to serve in an ex officio capacity.

Furthermore, the bill introduces provisions for the deannexation and reannexation of areas within animal services districts. A city, town, or county can withdraw from a district through a resolution or a petition from ten percent of voters, with the deannexation taking effect at the end of the year following voter approval. The reannexation process requires resolutions from both the governing body and the district, with immediate establishment of property tax boundaries upon adoption. The bill also allows for a voter referendum if a petition is filed within 30 days of the reannexation resolution, requiring a simple majority for approval. Additionally, the bill defines "deannex" and establishes that these provisions will constitute a new chapter in Title 35 RCW.
