News Washington State AI Bills 2026

Washington State AI Legislation — Governor Bob Ferguson signed four significant AI bills into law in March 2026, making Washington one of the most active states in regulating artificial intelligence.

Bills Signed Into Law

HB 1170 — AI Content Provenance and Disclosure

HB 1170, signed by Governor Ferguson on March 25, 2026, requires large AI providers (those with over 1 million monthly users and annual revenues exceeding $500 million) to disclose when content is AI-generated or substantially modified. Key provisions include:

• Manifest disclosures: Providers must offer users the option to include clear, conspicuous labels identifying AI-generated or AI-modified content that are difficult to remove
• Latent disclosures: Watermarks or metadata must be embedded in AI-generated or materially altered images, video, and audio
• Free detection tools: Covered providers must provide public AI detection tools
• Material alteration standard: Significant changes require disclosure, but minor edits like resizing, cropping, or color adjustments do not
• Effective date: February 1, 2027

HB 2225 — AI Companion Chatbot Safety

HB 2225, signed on March 24, 2026, regulates AI companion chatbots — defined as AI systems with natural language interfaces that provide adaptive, human-like responses, exhibit anthropomorphic features, and sustain relationships across multiple interactions. Key requirements include:

• Operators must clearly disclose that the chatbot is artificial and not human
• Disclosures must appear at the start of interaction, with reminders every three hours for adults and every hour for minors
• For minors: prohibition on sexually explicit content, mandatory "take a break" prompts, restrictions on engagement-maximizing tactics, and bans on emotional manipulation
• The definition excludes bots used solely for business operations, customer service, or technical assistance that do not sustain relationships, as well as video game bots and standalone voice assistants
• Effective date: January 1, 2027

SB 5395 — AI in Health Insurance Prior Authorization

SB 5395 increases restrictions on the use of AI in prior authorizations by health insurance carriers, requiring human oversight and preventing purely algorithmic denial of coverage determinations.

SSB 5886 — AI Deepfakes and Personality Rights

SSB 5886, signed on March 16, 2026, amends Washington's Personality Rights Law to address the use of a person's "forged digital likeness" without consent, expanding existing property rights law to cover AI-created realistic but deceptive audio and video. The law takes effect on June 11, 2026.

Context

Washington's legislative action is part of a broader wave of state-level AI regulation in early 2026, even as the federal government moves toward preempting state laws. These bills passed the same week as the Commerce Department identified multiple state AI laws as conflicting with national policy.

Washington's HB 1170 parallels Oregon's SB 1546 and California's SB 1000 in establishing AI content provenance requirements, while HB 2225 mirrors companion chatbot safety laws in California (SB 243) and Oregon (SB 1546).
