Maddy summaryHB 2503 requires developers of commercial generative artificial intelligence systems (like chatbots or image generators) to publicly disclose detailed information about the data used to train their systems by January 1, 2027. This includes sources, dataset types, whether personal or copyrighted data was used, steps taken to remove child sexual abuse material, and if synthetic data was generated. The law applies to developers making systems publicly available in Washington, excluding systems solely for security, aircraft operation, or national defense. Developers must provide this information without compromising trade secrets, and violations are treated as unfair business practices under Washington’s Consumer Protection Act.

Maddy summaryHB 1607 establishes a statewide recycling refund program for glass, plastic, and metal beverage containers in Washington. Under this program, consumers pay a deposit, referred to as an "applicable refund value," when purchasing covered beverages. They can then return the empty containers to designated express or full-service redemption sites to receive their refund back. The bill implements an extended producer responsibility framework, making brand owners responsible for compliance, with the goal of increasing recycling rates, reducing litter, and supporting a circular economy.
Maddy summaryHouse Resolution 4675, adopted on January 28, 2026, is a ceremonial resolution expressing the Washington State House of Representatives' gratitude to the Washington National Guard for their service. It specifically acknowledges the Guard's roles in emergency response (including flood operations and search-and-rescue missions), disaster recovery efforts (like adapting from the Oso landslide), and national defense support (such as aerial refueling capabilities). The resolution directs copies to the Adjutant General, Governor, and other officials but does not create new laws or alter policies. It directly honors National Guard members, their families, and employers without imposing any financial or operational requirements.
Maddy summaryHB 2564 requires Washington's health benefit exchange to add new state-specific criteria to its health plan certification process, directly affecting health insurance plans sold through the state's marketplace. The bill mandates the exchange to annually review market conditions and develop certification criteria focused on improving access and affordability - including factors like cost-sharing, provider networks, and premium differences - before certifying plans for the next year. These criteria must be developed with public input from insurers, tribes, and health care stakeholders, following a detailed timeline including public hearings. The change supplements existing federal certification standards but targets Washington residents' specific access and affordability challenges in the insurance marketplace.
Maddy summaryHB 2170 would authorize Washington’s Department of Natural Resources to generate revenue from state lands and waters through carbon credit programs and other ecosystem service projects, such as reforestation, kelp restoration, and water purification. The bill directly affects the department (which manages 6 million acres of state lands) and trust beneficiaries by enabling it to enter carbon markets like private landowners already do, with contracts lasting up to 125 years. Key provisions include requiring board approval for minimum payments, allowing sales of ecosystem service credits to markets, and directing proceeds to state accounts for environmental projects like salmon habitat improvement. The bill aims to diversify state revenue streams while leveraging natural climate solutions, aligning with Washington’s existing cap-and-invest climate program. It remains a proposed bill (prefiled but not yet enacted).
Maddy summaryHB 2227 would exempt sales of "qualified affordable housing" from Washington's real estate excise tax. This bill amends the state's tax code (RCW 82.45.010) to create this specific exemption for qualifying affordable housing properties. The exemption directly affects sellers of eligible affordable housing units, reducing their tax burden when selling such properties. The bill is currently pending in the House Finance Committee after being prefaced in December 2025.
Maddy summaryHB 2516 places a two-year moratorium (January 2027-December 2028) on the use of anticoagulant rodenticides and rodenticides containing bromethalin, prohibiting their sale and application except for limited emergencies like drinking water protection or disease control. The bill requires the Washington State Academy of Sciences to study rodenticide impacts on wildlife and research safer alternatives, with findings due by December 2028. This directly affects pest control professionals, property managers, and agricultural operations that currently use these chemicals. The moratorium expires June 30, 2029, unless extended by future legislation.
Maddy summaryHB 2673 proposes a tax exemption for property used as affordable housing owned or operated by social housing agencies in Washington State. This bill directly affects affordable housing providers by removing certain property taxes on qualifying properties. The key mechanism adds an exemption to existing tax codes, specifically excluding from taxation real property used for affordable housing under a social housing agency's ownership or operation. The exemption applies to properties meeting the bill's defined criteria for affordable housing use, without altering other tax obligations.
Maddy summaryHB 2381 creates a performance-based compliance pathway for low-rise residential buildings (1-6 stories, up to 24 units) in Washington, replacing rigid prescriptive building code requirements. It directs the State Building Code Council to develop a new appendix to the building code, allowing builders to demonstrate compliance through measurable performance standards (like structural safety or energy efficiency) instead of specific construction methods. This system enables reuse of certified designs across jurisdictions, reduces redundant permitting reviews, and aligns with existing energy and emissions programs. The bill directly affects builders, developers, and local building departments by streamlining approvals and supporting industrialized housing production to address the state's housing shortage.
Maddy summaryHB 2542 requires Washington-based animal testing facilities, contract testing facilities, and drug manufacturers to use non-animal test methods for drug development when scientifically valid alternatives are available. It prohibits the use of animal test methods in the drug development process (including discovery and preclinical research) if equivalent or better alternatives exist, defined as methods validated by federal bodies that don’t involve animals. The law does not apply if federal regulations mandate animal testing, and violations are treated as unfair trade practices under Washington’s consumer protection law. This directly affects entities conducting drug safety and efficacy testing within the state, aiming to align with federal policy supporting non-animal testing methods.
