Subnational jurisdiction · as of 2026-07-15

California has enacted four major age-gating and minor online safety statutes and is considering two more. The Age-Appropriate Design Code Act (AB 2273, 2022) remains substantially enjoined after a March 2026 Ninth Circuit ruling that left its data protection impact assessment requirement enjoined, upheld the injunction on its data use and dark patterns provisions on vagueness grounds, and lifted the injunction on its coverage definition and age estimation requirement while remanding for further severability analysis. The Protecting Our Kids from Social Media Addiction Act (SB 976, 2024) is largely in effect after a September 2025 Ninth Circuit ruling, except for its default setting that hides like and share counts, which the court ordered enjoined; its age verification component does not take effect until 2027. The Digital Age Assurance Act (AB 1043, 2025) requires device level age signals starting January 1, 2027, and AB 56 (2025) requires mental health warning labels for users under 18 on addictive platforms starting the same day. Two pending bills, AB 1709 (a social media minimum age proposal) and AB 1856 (which would extend age signals to browsers and websites), have each passed the Assembly and are in the Senate Appropriations Committee. California has no adult content age verification law in effect; a 2024 attempt, AB 3080, died in the Senate Appropriations Committee.

Cal. Health & Safety Code §§ 27000-27007

Effective 2025-01-01 · Applies to private

Litigation: 9th Cir. No. 25-146; N.D. Cal. No. 5:24-cv-07885-EJD (U.S. Court of Appeals for the Ninth Circuit). A September 9, 2025 ruling affirmed denial of an injunction as to most provisions but ordered the district court to enjoin the default setting that hides like and share counts on minors' posts, finding that provision likely violates the First Amendment. The age verification requirement's challenge was found unripe because it does not start until 2027.
