At a glance
- California has no single AI act. As of October 2026 it regulates AI through at least fourteen statutes and regulations, sorted by use: hiring and discipline, patient care, legal practice, frontier model development, generative AI disclosures, and automated decisions about consumers.
- SB 53, AB 2013, SB 243, and AB 489 took effect January 1, 2026. The California AI Transparency Act became operative August 2, 2026. From January 1, 2027, the CPPA’s automated decisionmaking rules, AB 1883, SB 951, AB 1979, SB 503, SB 574, and AB 1609 apply, and SB 947 and the SB 1119 child safety duties follow on July 1, 2027.
- Enforcement is split. Only the Attorney General may recover SB 53 civil penalties; the CPPA and the Attorney General enforce the privacy rules; the Labor Commissioner and public prosecutors enforce SB 947 and AB 1883, while SB 951 adds to existing Cal/WARN notice duties; health care enforcement runs through licensing boards, state facility and clinic licensing, the Department of Managed Health Care, and the Department of Insurance; SB 503 names no enforcer; and SB 243 gives injured users a private right of action.
- Executive Order 14365 directs the Attorney General to form a task force to challenge state AI laws inconsistent with its national AI policy, but no federal statute expressly preempts California’s. Each law stays enforceable unless a court rules against it.
Which California AI laws are in force in 2026?
As of October 2026, the principal California AI laws in force include SB 53 (frontier model transparency), AB 2013 (training data disclosure), the California AI Transparency Act (generative AI content disclosures, as amended by AB 853 and, in 2026, by SB 1000 and AB 2713), SB 243 (companion chatbots), AB 489 (AI and health care license terms), AB 3030 and SB 1120 (patient communications and utilization review), AB 325 (common pricing algorithms), and the Civil Rights Council’s automated-decision system regulations for employers. From January 1, 2027, the privacy agency’s automated decisionmaking rules apply, along with AB 1883, SB 951, AB 1979, SB 503, and SB 574, all signed September 30, 2026, and AB 1609; SB 947, signed the same day, is operative July 1, 2027.

What do California employers have to do about AI?
California’s employer rules arrive in three stages. The Civil Rights Council regulations have applied since October 1, 2025. The privacy agency’s ADMT rules, AB 1883, and SB 951 apply from January 1, 2027. SB 947 applies from July 1, 2027.
The civil rights regulations treat discriminatory use of an automated-decision system as a potential FEHA violation and define an employer’s agent to include anyone acting on its behalf, including through an automated-decision system. The regulations do not require anti-bias testing, but evidence of anti-bias testing or similar proactive efforts, or the lack of that evidence, is relevant to a claim or an available defense. Records, including ADS data, must be kept at least four years.
The privacy rules reach fewer employers: only for-profit businesses that meet a CCPA threshold, such as annual gross revenue above $26,625,000. For those businesses, hiring, allocation or assignment of work, compensation, promotion, demotion, suspension, and termination are significant decisions. A pre-use notice must state, among other things, the specific purpose of the ADMT, the opt-out and access rights, and how the technology works; a generic purpose such as “to make a significant decision” does not satisfy the rule. The opt-out right has exceptions, including a human appeal to a reviewer with authority to overturn the decision, and, for hiring, use of an ADMT solely to assess the applicant’s ability to perform at work, or, for allocation or assignment of work and compensation, use of an ADMT solely for that purpose, where in either case the ADMT works for the business’s purpose and does not unlawfully discriminate based on protected characteristics (11 CCR 7221(b)).
SB 947 adds the hardest line. From July 1, 2027, an employer may not rely solely on an ADS to discipline or terminate an employee. Where it relies primarily on one, a human must corroborate the output, and the employee gets a written post-use notice at the time the employer informs the employee of the decision. In an action over the sole-reliance or corroboration rules, once an ADS is shown to have been used to make the decision, the employer must show that it did not primarily rely on the ADS or that it complied with the corroboration and post-use notice requirements (Labor Code 1526.1(c)). The law does not apply under a collective bargaining agreement that explicitly waives it and meets its other conditions, or where a federal statute, regulation, or binding federal contract on aircraft or defense work requires the system or makes it reasonably necessary. An employer that gives SB 947 notices is relieved of substantially similar ADS notice duties under other state laws, except that a business subject to the CCPA remains subject to the CPPA’s ADMT regulations (Labor Code 1526.3 and 1526.4).
The employers and HR page covers headcount thresholds, the New York City and Illinois rules, and Mobley v. Workday.
Which California AI laws reach hospitals, clinics, and health plans?
Five statutes, each triggered by a different use. AB 3030 reaches generative AI patient messages about clinical information. SB 1120 reaches AI in a plan’s medical necessity review, including review the plan delegates to medical groups. AB 489 reaches any AI product that calls itself a doctor, nurse, or other protected title. AB 1979 and SB 503, from January 1, 2027, reach clinical decision support systems and AI used in clinical functions.
The AB 3030 exemption decides most workflows: a message that a licensed or certified provider read and reviewed needs no disclaimer. An unreviewed draft sent to a patient does, and the disclaimer placement differs by medium: at the beginning of a letter or email, throughout a chat or video session, and at the start and end of an audio interaction.
AB 1979 stops short of banning clinical AI. Automated documentation and communication that involves no professional judgment, including messages telling patients their records were updated and reminders, is outside it. AB 1979 also deems a business that offers a health care chatbot to consumers, for managing their information or for diagnosis, treatment, or management of a medical condition, a provider of health care subject to the Confidentiality of Medical Information Act (Civil Code 56.06(f)). SB 503 names no enforcer, and compliance is not a defense to a discrimination claim; the practical duty is an inventory of decision support systems with foreseeable bias risk, vendor documentation, and ongoing monitoring. The hospitals and health systems page sets these against Section 1557, HIPAA, and FDA device law.
What does SB 574 require of lawyers who use generative AI?
From January 1, 2027, SB 574 moves duties that had lived in bar guidance into statute. A California attorney may not delegate the practice of law to generative AI; may not enter confidential, personal identifying, or other nonpublic information into a generative AI system unless access is restricted to the attorney and persons the attorney authorizes under obligations to protect its confidentiality; must take reasonable steps to verify the accuracy of outputs, including all case and statutory citations, and correct any erroneous or hallucinated output in material the attorney uses; must disclose generative AI use to the court for all documents submitted to the court; and must consider whether to disclose it in content provided to the public.
The amended Code of Civil Procedure section 128.7 applies to every filer, not only to AI users: no brief, pleading, motion, or other paper may contain a citation the responsible attorney has not personally verified, whatever its source. New section 1282.1 bars an arbitrator from delegating any part of the decisionmaking process to a generative AI tool, and from relying on information generated by generative AI outside the record without appropriate disclosure to the parties beforehand and, as far as practical, a chance for them to comment. Section 6068.1 does not prescribe the form of the court disclosure; check each court’s local rules and each judge’s standing orders. The law firms page covers the ethics opinions and the sanctions cases.
Who has to comply with SB 53?
SB 53 reaches a short list. A frontier developer is a person who trained, or initiated training of, a foundation model using more than 10²⁶ integer or floating-point operations. A large frontier developer is one whose group, with affiliates, had annual gross revenues above $500 million in the preceding calendar year. The compute count includes the original training run and any later fine-tuning, reinforcement learning, or other material modification the developer applies to a preceding foundation model (Business and Professions Code 22757.11(i)(2)). A company that only deploys a model it did not train is not a frontier developer; a company that fine-tunes or otherwise modifies another developer’s foundation model should apply that counting rule before concluding it is outside the statute.
Every frontier developer must publish a transparency report before or at the time it deploys a new or substantially modified frontier model, and must report a critical safety incident to the Office of Emergency Services within 15 days of discovery, or within 24 hours to an appropriate authority where the incident poses an imminent risk of death or serious physical injury. A large frontier developer must also write, implement, comply with, and publish a frontier AI framework covering, among other things, catastrophic risk thresholds, mitigations, third-party assessments, cybersecurity of unreleased weights, and internal governance; may not make a materially false or misleading statement about its implementation of, or compliance with, that framework; and must send the Office of Emergency Services a summary of any assessment of catastrophic risk from internal use of its frontier models every three months or on another reasonable schedule it communicates in writing. Labor Code sections 1107 to 1107.2 protect covered employees who report a specific and substantial danger from catastrophic risk, or a violation, to the Attorney General, a federal authority, a person with authority over them, or another covered employee with authority to investigate, discover, or correct the issue.
The civil penalty in Business and Professions Code 22757.15 applies to a large frontier developer, depends on the severity of the violation, does not exceed $1,000,000 per violation, and may be recovered only in a civil action brought by the Attorney General. A covered employee may bring a civil action under the whistleblower provisions (Labor Code 1107.1).
Which California AI laws apply regardless of industry?
These laws turn on what a product does rather than who sells it.
- AB 2013. A developer of a generative AI system or service released on or after January 1, 2022 and made available to Californians had to post, on or before January 1, 2026 and before each later release, a high-level summary of the datasets used in development. xAI sued; the Central District of California denied a preliminary injunction on March 4, 2026, and the appeal (Ninth Circuit No. 26-1591) was pending as of October 2026, with oral argument set for November 18, 2026 on the Ninth Circuit’s calendar. The law is enforceable while the appeal proceeds.
- California AI Transparency Act. AB 853 moved the operative date from January 1, 2026 to August 2, 2026, and added duties for large online platforms and GenAI system hosting platforms from January 1, 2027 and for capture device manufacturers from January 1, 2028. Two 2026 amendments changed it. SB 1000 (Chapter 861), an urgency statute effective on signing on September 30, 2026, deleted the 1,000,000-user threshold from the covered provider definition, renamed the AI detection tool a disclosure verification tool, dropped the duty to offer a manifest disclosure, and exempts GenAI systems designed to primarily function as assistive technology until January 1, 2029. AB 2713 (Chapter 856) revised the large online platform duties that start January 1, 2027. Read the current text of Business and Professions Code 22757.1 to 22757.6 rather than a 2024 summary.
- SB 243. A companion chatbot operator must disclose the AI where a reasonable person would be misled into thinking it human, maintain and publish a suicide and self-harm protocol, and, from July 1, 2027, report annually to the Office of Suicide Prevention. SB 1119 (Chapter 190, Statutes of 2026), chaptered September 10, 2026, deletes SB 243’s known-minor provisions effective January 1, 2027 and adds a child safety chapter (Business and Professions Code 21810 et seq.). Every operator must either determine users’ ages as the statute directs or apply the chapter’s child protections to all users. From July 1, 2027, an operator that allows child users must, among other duties, perform and document a child safety risk assessment, and take and document mitigation measures, before a new or substantially modified companion chatbot is offered. Public prosecutors may seek civil penalties of up to $5,000 per affected child for each negligent violation and up to $15,000 per affected child for each intentional violation.
- Customer service chatbots. From January 1, 2027, AB 1609 (Chapter 733, Statutes of 2026, signed September 28, 2026) bars a business with more than $500 million in national gross annual revenue from representing that a customer service chatbot is human; requires a clear and conspicuous disclosure, in the chatbot’s medium, that it is not human where a reasonable person is likely to be misled; and requires, during at least regular business hours, a simple way on every customer service platform to request a human agent, with a good-faith effort to connect the customer within 15 minutes or schedule a contact within one business day. Public prosecutors enforce it, with civil penalties of up to $5,000 for an initial violation and $10,000 for each subsequent one; there is no private right of action, and the statute excludes hospitals’ health care communications, consumer reporting agencies, exclusive business lines, and certain telecommunications and water services regulated by the Public Utilities Commission.
- AB 325. Since January 1, 2026 it has been unlawful to use or distribute a common pricing algorithm as part of a contract, combination, or conspiracy in restraint of trade, or while coercing another person to adopt its recommended price or commercial term. The pricing guide covers it.
What do the CPPA’s automated decisionmaking rules require?
The privacy agency’s regulations, approved by the Office of Administrative Law and announced September 23, 2025, took effect January 1, 2026. Article 11 applies to a business that uses ADMT to make a significant decision about a consumer; a business already doing so must comply by January 1, 2027, and one that starts on or after that date must comply from the start (11 CCR 7200).
ADMT means technology that processes personal information and uses computation to replace or substantially replace human decisionmaking. “Substantially replace” means the output is used without human involvement, and human involvement requires a reviewer who knows how to interpret the output, reviews it with other relevant information, and has authority to make or change the decision (11 CCR 7001(e)). Spam filters, spreadsheets, calculators, and similar tools are excluded if they do not replace human decisionmaking. Advertising is not a significant decision.
Three duties follow: a pre-use notice (7220), a right to opt out with the exceptions described above (7221), and a right to access a plain-language explanation of the ADMT’s purpose, logic, and outcome (7222). Trade secrets and information that would compromise security, fraud prevention, or safety need not be disclosed. A risk assessment is required before starting processing that presents significant risk to consumers’ privacy, including using ADMT for a significant decision, profiling workers or students through systematic observation, certain training uses, selling or sharing personal information, and processing sensitive personal information (7150); processing already under way before January 1, 2026 must be assessed by December 31, 2027 (7155(b)); assessments must be reviewed at least every three years and updated within 45 days of a material change (7155). Attestations and summaries for assessments conducted in 2026 and 2027 are due to the agency by April 1, 2028 (7157).
What should a company doing business in California do in the first 90 days?
- Inventory every AI system and mark the ones that make or substantially replace a human decision about hiring, work assignment, pay, discipline, credit, housing, education, or health care
- Decide whether the company meets a CCPA threshold; if so, draft the 11 CCR 7220 pre-use notice and choose between an opt-out and a qualifying human appeal for each significant decision before January 1, 2027
- Complete and document a risk assessment before any ADMT is used for a significant decision, with the April 1, 2028 submission in the calendar
- Confirm the four-year FEHA retention period covers automated-decision system data, and record any adverse impact testing
- Find and switch off any workplace surveillance feature that infers emotional state or collects neural data by January 1, 2027, unless an AB 1883 exception applies
- Before July 1, 2027, remove sole reliance on an automated decision system for discipline or termination and build human corroboration and the SB 947 post-use notice into any decision that relies primarily on one
- If the company develops a public generative AI system, post the AB 2013 training data summary and check the California AI Transparency Act duties that applied from August 2, 2026
- If any product talks to consumers as a companion or a customer service chatbot, apply the SB 243 disclosures and protocol now, the AB 1609 duties from January 1, 2027 if the business has more than $500 million in national gross annual revenue, and the SB 1119 child safety duties from July 1, 2027
- In health care, add AB 3030 disclaimers or a documented clinician review step, remove protected titles from AI product names and functionality, and inventory clinical decision support systems for AB 1979 and SB 503
- In legal departments, set SB 574 procedures for confidentiality, citation verification, and court disclosure before January 1, 2027
How this fits the other guides: the US state AI laws guide is the hub for this page and covers Colorado, Texas, Utah, Illinois, New York, and the federal preemption push. The employers and HR, hospitals and health systems, and law firms pages apply the California rules alongside federal law for each reader.
This page is general information as of October 2026, not legal advice. California statutes, regulations, and court orders in this area change often; confirm the current text with the Legislature, the regulator, or counsel.
Common questions
Does California have a single AI law?
No. As of October 2026 California regulates AI through separate statutes and regulations sorted by use, including SB 53 for frontier model developers, AB 2013 for generative AI training data, the CPPA's automated decisionmaking rules for significant decisions about consumers, Civil Rights Council regulations and SB 947 for employers, AB 3030, SB 1120, AB 489, AB 1979, and SB 503 for health care, and SB 574 for attorneys.
When do California's new AI laws take effect?
SB 53, AB 2013, SB 243, and AB 489 took effect January 1, 2026, and the California AI Transparency Act became operative August 2, 2026. The CPPA's ADMT duties, AB 1883, SB 951, AB 1979, SB 503, SB 574, and AB 1609 apply from January 1, 2027. SB 947, which bars sole reliance on an automated decision system to discipline or terminate an employee, is operative July 1, 2027, as are SB 1119's risk assessment and other child safety duties for companion chatbot operators that allow child users.
Who has to comply with California SB 53?
Frontier developers, meaning anyone who trained a foundation model using more than 10^26 integer or floating-point operations, must publish a transparency report at deployment and report critical safety incidents to the Office of Emergency Services within 15 days of discovery. Large frontier developers, those with more than $500 million in annual gross revenue with affiliates in the preceding year, must also publish a frontier AI framework. Civil penalties of up to $1,000,000 per violation apply to large frontier developers and may be recovered only by the Attorney General; covered employees may sue under the law's whistleblower provisions.
