Partially in forceApproach: Targeted statutes: health data now, chatbots and provenance next

Washington regulates AI through targeted statutes rather than a framework. The My Health My Data Act, with its private right of action, already reaches AI systems handling consumer health data and inferences. In March 2026 the legislature passed two more: HB 2225 on chatbots and HB 1170 on content provenance, extending the pattern of narrow, enforceable rules.

Key points

  • My Health My Data Act (2023 to 2024 phase-in) covers health data broadly, including inferences AI systems draw, with a private right of action.
  • HB 2225 (chatbots) and HB 1170 (provenance) passed the legislature in March 2026.
  • AI-in-government statutes and health-insurer AI restrictions add to the targeted stack; no comprehensive consumer AI law yet.
