Washington AI-Generated Content Disclosure Act (HB 1170): AI Compliance Requirements
Washington HB 1170, signed by Governor Bob Ferguson on March 24, 2026, requires "covered providers" — entities whose generative AI system has over 1,000,000 monthly users and is publicly accessible to Washington consumers for personal use (state/local/tribal governments excluded) — to enable users to determine whether content was generated or materially altered by that provider's generative-AI system, via disclosures such as visible watermarks or embedded metadata that let substantially modified content be traced back as AI output. Effective February 1, 2027. Real statutory exemptions: business-to-business generative-AI use/sale/licensing/distribution; products/services that exclusively provide video games or interactive experiences; and systems used solely for upscaling, noise reduction, or compression. Enforced EXCLUSIVELY by the Washington Attorney General under the Consumer Protection Act (violations presumed to affect the public interest) — there is NO private right of action.

Key Facts
February 1, 2027
Washington AG-only enforcement under the Consumer Protection Act, ch. 19.86 RCW (violations presumed to affect the public interest); no private right of action. HB 1170 itself sets no separate per-violation dollar figure — exposure runs through the CPA's existing remedies, the same structure as sibling Washington AI statutes (HB 2225).
What Your Business Must Do
2 compliance requirements identified. Critical requirements carry the highest risk of enforcement action.
AI Content Provenance Disclosure (Covered Providers Only)
Medium PriorityIf you are a "covered provider" — your generative AI system has over 1,000,000 monthly users and is publicly accessible to Washington consumers for personal use — you must enable users to determine whether content was generated or materially altered by your generative-AI system, via a disclosure mechanism such as a visible watermark or embedded metadata that lets substantially modified content be traced back as AI output. State, local, and tribal governments are excluded from the covered-provider definition. Also excluded: business-to-business generative-AI use/sale/licensing/distribution; products/services that exclusively provide video games or interactive experiences; and systems used solely for upscaling, noise reduction, or compression. Below the 1M-monthly-user threshold, or within an exemption, this mandatory duty does not apply.
Deadline: February 1, 2027
Washington HB 1170 (2026)AI Content Policy Update
Medium PriorityUpdate your AI use and content policies to document how AI-generated content is labeled, distinguished from human-generated content, and disclosed to users. This policy supports both Washington HB 1170 compliance and similar emerging laws in other jurisdictions (EU AI Act transparency requirements).
Deadline: February 1, 2027
Washington HB 1170 (2026)Who Does This Apply To?
Applies to "covered providers" — entities whose generative AI system has over 1,000,000 monthly users and is publicly accessible to Washington consumers for personal use — effective February 1, 2027 under HB 1170 (NOT "large technology companies" in a loose sense; the statute sets a precise numeric threshold). In scope means: enabling users to determine whether content was generated or materially altered by the provider's generative-AI system, via a disclosure mechanism such as a visible watermark or embedded metadata. Real statutory exclusions: state/local/tribal governments; business-to-business generative-AI use/sale/licensing/distribution; products/services that exclusively provide video games or interactive experiences; and systems used solely for upscaling, noise reduction, or compression. Enforced EXCLUSIVELY by the Washington AG under the Consumer Protection Act (violations presumed to affect the public interest) — there is NO private right of action, unlike sibling HB 2225.
Recent Regulatory Guidance
Transparency Coalition — Washington Governor Signs Two Major AI Safety Bills (March 2026)
Following Governor Ferguson's March 2026 signature of HB 1170 alongside HB 2225, leading transparency advocates published the operative interpretation: HB 1170 primarily targets large technology platforms — applicability thresholds will be set in WA AG rulemaking; smaller businesses are encouraged but not required to adopt C2PA-compatible watermarking; AI-substantial-modification-disclosure is mandatory for platforms covered by the rule. The bill explicitly aligns with EU AI Act Article 50 transparency requirements to enable harmonized US/EU compliance.
