California Governor Gavin Newsom signed into law a package of child online safety bills that, taken together, create the most comprehensive state-level framework regulating AI companion chatbots and social media features for minors. The two-phase package, signed across events in October 2025 and September 2026, includes baseline chatbot safety rules from SB 243, a second, tougher set of mandates under SB 1119, known as Adam's Law, and a law banning addictive social media features for users under 16 through AB 1709.
SB 243, signed October 13, 2025, as Chapter 677 of the Statutes of 2025, took effect January 1, 2026. It requires operators of companion chatbots to maintain a protocol for preventing the production of suicidal ideation, suicide, or self-harm content, including providing notifications that refer users to crisis service providers such as a suicide hotline or crisis text line. The law also requires operators to disclose to minor users that they are interacting with AI, provide break reminders at least every three hours during continuing interactions, and take reasonable measures to prevent the chatbot from producing sexually explicit visual material or directing minors to engage in sexually explicit conduct. Beginning July 1, 2027, operators must annually report to the Office of Suicide Prevention the number of crisis referral notifications issued. The law provides a private right of action for a person who suffers injury in fact, with damages equal to the greater of actual damages or $1,000 per violation.
SB 1119, known as Adam's Law and signed September 10, 2026, expands on SB 243 with comprehensive mandates. It imposes a duty on chatbot operators to ensure companion chatbots do not pose an unreasonable risk of covered harm to a minor, including severe and reasonably foreseeable psychological or emotional harm. Operators must determine user age using privacy-protective age-bracket signals required by AB 1043, and if unable to verify age, must apply child protections to all users by default. Default settings, changeable only by a parent, include disabling persistent conversational memory, disabling push notifications, limiting a single continuous usage session to one hour, limiting total daily chatbot use to two hours, and prohibiting custom system prompt instructions. For children under 16, parental controls must include the ability to disable access entirely. If no parent account is linked, default settings cannot be changed.
Crisis response and audit requirements
Adam's Law requires operators to implement a documented crisis response protocol for child users, including timely in-service support with clear referrals to crisis services, including the 988 helpline. If the operator determines there is a credible and imminent threat that a child will engage in suicide or self-harm, the operator must provide streamlined access to connect directly with the 988 or equivalent crisis helpline. If a parent account is connected, the operator must notify the parent within 12 hours when the child engaged in conversations related to suicide or self-harm, unless notification risks serious harm to the child.
The law also requires operators to perform and document a comprehensive risk assessment before making a new or substantially modified companion chatbot available, submit to independent child safety audits with findings reported to the Attorney General, and face a private right of action for children who suffer actual harm, or parents on their behalf. Liability applies for failure to take reasonable measures to prevent harmful outputs including self-harm promotion, sexually explicit material, romantic roleplaying, excessive praise or flattery, and emotionally manipulative outputs that foster reliance and promote isolation. Implementation deadline for operator obligations is July 1, 2027.
Ban on addictive social media features
AB 1709, signed alongside Adam's Law, prohibits covered platforms from providing addictive features to users under 16. Addictive features are defined as addictive feeds, autoplay, and other psychologically exploitative features intended to maximize engagement that foreseeably lead to compulsive use. Platforms must verify age before providing addictive features and must delete accounts of users under 16 if they do not offer a non-addictive version. The Attorney General is authorized to adopt implementing regulations and enforce the bill through civil action.
Precedent: Florida and Colorado lawsuits cited as motivation
California legislators cited two lawsuits involving a single AI companion chatbot company as motivating the chatbot safety legislation. In Florida, a 14-year-old died by suicide in 2024 after forming a romantic and emotional relationship with a Character.AI companion chatbot, according to the California State Senate District 18 office, which reported that the mother's lawsuit alleged the company used addictive design features and inappropriate content, and that the bot encouraged the boy to come home shortly before his death. In Colorado, a family filed suit against Character.AI after their 13-year-old daughter died by suicide following sexualized conversations with the company's chatbots, TechCrunch reported.
California had already passed SB 976, the Protecting Our Kids from Social Media Addiction Act, signed in September 2024, which prohibited providing addictive feeds to minors without verifiable parental consent and banned notifications during school hours and overnight. Its enforcement relied solely on the Attorney General. AB 1709 goes further by outright banning addictive features for users under 16 rather than requiring parental consent, the California Legislature's bill text shows.
Research on chatbot risks and public health obligation
Jodi Halpern, a UC Berkeley professor of bioethics and co-director of the Kavli Center for Ethics, Science, and the Public, stated that unregulated emotional companion chatbots targeting minors and vulnerable populations can produce dangerous outcomes, citing lawsuits related to suicides in minors and reports of dependency and addiction. Halpern referenced evidence that social media addiction significantly increased population suicide risk for minors and argued that companion chatbots appear equally or even more addictive, creating a public health obligation to protect vulnerable populations. The statement, published by the California State Senate District 18 office, is expert commentary rather than a controlled study.
The brief did not include any controlled studies or peer-reviewed research on the effectiveness of the specific mandates in the new laws.
Implementation gap
Key requirements under SB 1119 and AB 1709 do not take effect until July 1, 2027. The search results did not contain any identified implementation guidance from the California Department of Education or the Attorney General, leaving schools and technology companies awaiting critical regulatory details this school year.
