Concerning the United States government joining the global community in formally developing a fossil fuel non-proliferation treaty.

Maddy summaryHouse Joint Memorial 4003 is a non-binding resolution from the Washington State Legislature urging the U.S. government to join international efforts in developing a Fossil Fuel Non-Proliferation Treaty. It calls for ending new fossil fuel exploration and expansion, phasing out existing production in line with climate science, and prioritizing worker and community support during the transition. The memorial aligns with Washington’s existing climate laws, including the Climate Commitment Act and the HEAL Act, which aim to reduce emissions and address environmental health disparities. It directly addresses the U.S. President, Congress, and the United Nations to advance global climate action.

Increasing tobacco and vapor products taxes.

Maddy summaryHB 1416 increases taxes on tobacco and vapor products in Washington State. It adds a $0.015 tax per cigarette and establishes new per-milliliter tax rates for vapor products: $0.30 per ml for most products and $0.10 per ml for containers over 5 ml. The bill requires distributors to collect these taxes at the point of sale or distribution and directs 50% of the revenue to cancer research and 50% to public health services. These changes apply to manufacturers, distributors, retailers, and consumers of tobacco and vapor products, with the tax taking effect October 1, 2025.

Concerning law enforcement and local corrections agency misconduct through investigations and legal actions.

Maddy summaryHB 1056 empowers Washington's Attorney General to investigate and take legal action against local law enforcement and corrections agencies for systemic misconduct, such as excessive force, discriminatory practices, or inadequate detention conditions. The bill allows the AG to issue civil investigative demands, file lawsuits for systemic reforms, and seek court-ordered policy changes without addressing individual officer misconduct. It specifically applies to county and city agencies (excluding state entities like the Washington State Patrol) and requires coordination with federal investigations. The law does not replace existing legal remedies but aims to promote consistent accountability and transparency in local policing and corrections practices.

Defining the rental or lease of individual storage space at self-service storage facilities as a retail transaction for the imposition of business and occupation and sales and use taxes.

Maddy summaryHB 1907 classifies the rental or lease of individual storage spaces at self-service storage facilities as a "retail transaction" for tax purposes. This means self-storage facilities must collect and remit business and occupation taxes and sales taxes on these rentals, aligning them with other retail services. The bill amends Washington State law (RCW 82.04.050) to explicitly include storage rentals under the definition of taxable retail sales, affecting both the facilities (as taxpayers) and their customers (who pay the tax). It does not create new taxes but changes the tax treatment of an existing service. The bill is currently under review in the House Finance Committee.

Prohibiting the sale of certain tobacco and nicotine products.

Maddy summaryHB 1203 prohibits the sale of all flavored tobacco and nicotine products (including fruit, mint, or candy flavors) and entertainment vapor products with gaming features (like Pac-Man) starting January 1, 2026. It directly affects retailers who sell these products and aims to reduce youth vaping, as 88% of youth vapers use flavored products. The bill defines "flavored" broadly to include any non-tobacco taste or cooling sensation, and bans interactive devices that display games or videos. This targets products marketed to youth, such as those with cotton candy flavors or menthol cigarettes, which the bill states contribute to addiction and health disparities in Black and Hispanic communities. The law applies to all tobacco/nicotine products sold in Washington, excluding FDA-approved nicotine therapies and cannabis products.

In committee · Washington House · Co-sponsor
Authorizing middle housing in unincorporated growth areas and unincorporated urban growth areas, certain limited areas of more intensive rural development, and fully contained communities.

Maddy summaryHB 1840 authorizes counties to allow "middle housing" (like duplexes, triplexes, or townhouses) in designated unincorporated urban growth areas, specific rural development zones, and established communities. It requires at least one middle housing unit per single-family lot in urban areas and limits these developments to four units per lot in rural zones. The bill mandates that counties apply the same zoning, permit, and environmental rules to middle housing as to single-family homes, while requiring sewer service for rural middle housing. This policy aims to increase housing density without new infrastructure, directly affecting homeowners and developers in targeted areas.

Authorizing funding tools to mitigate the impact of sales tax sourcing in certain cities that host industrial and warehousing industries.

Maddy summaryHB 1532 allows specific cities (with populations over 120,000, located in high-population counties, and where industrial/warehousing makes up over 25% of property valuation) to add a 0.3% sales tax to offset fiscal challenges caused by current sales tax laws. This supplemental tax, collected on taxable transactions within the city, must fund community improvements like infrastructure or services to boost local vitality. Cities using this authority must hold public meetings, maintain a budget transparency webpage, and survey residents before each biennial budget. The bill replaces an expiring state funding program set to end in July 2026.

Enhancing public safety by limiting bulk purchases and transfers of firearms and ammunition.

Maddy summaryHB 1132 updates Washington's firearm dealer licensing rules to enhance safety. It requires dealers to implement strict security measures, including alarms monitored by law enforcement, locked storage for firearms during non-business hours, and digital surveillance systems covering all sales areas. The bill mandates annual background checks for all employees selling firearms and prohibits temporary sales outside licensed locations except at designated gun shows. It also requires dealers to annually certify compliance with all licensing conditions and face permanent license loss for violations. These provisions directly affect licensed firearm dealers operating in Washington state.

Enhancing consumer protections for automobile insurance coverage.

Maddy summaryHB 1645 requires Washington auto insurance policies covering car damage (physical damage coverage) to include a mandatory appraisal process for resolving disputes over repair costs. If insurers and policyholders disagree on the value of damage, they must use this process: each selects an appraiser, then an umpire if needed, with clear rules for cost-sharing. Policyholders get reimbursed for appraisal costs if the final valuation exceeds the insurer’s initial offer by $500 or more. This applies to all policies issued or renewed on or after January 1, 2026.

Ensuring patient choice and access to care by prohibiting unfair and deceptive dental insurance practices.

Maddy summaryHB 1535 prohibits dental insurers from restricting patient choice or limiting care based on network agreements, requiring dentists to make treatment decisions with patients rather than insurers. It mandates that at least 85% of dental insurance premiums be spent directly on patient care, not administrative costs, and gives patients the right to request independent reviews for denied claims. The bill directly affects dental patients (ensuring access to chosen providers and fair coverage), dentists (protecting their clinical autonomy), and dental insurers (requiring compliance with transparency and spending rules). These changes aim to create a fairer system by aligning dental insurance protections with medical insurance standards and reducing out-of-pocket costs for Washington residents.
