AB 1018: Automated decision systems.
What AB 1018 does, verified September 1, 2026
The bill aims to regulate the development and deployment of automated decision systems (ADS) used to make consequential decisions. An ADS is a computational process derived from machine learning, statistical modeling, or artificial intelligence that issues simplified output, such as a score or classification, to assist or replace human discretionary decision-making and impacts natural persons. Developers of covered ADSs must conduct impact assessments and provide deployers with certain information, including a high-level summary of the results. Deployers must also provide disclosures to subjects of consequential decisions made or facilitated by the ADS and offer an opportunity to appeal the outcome. The bill requires the attorney general to receive an unredacted copy of the impact assessment within 30 days of a request. Public entities, including the attorney general, are authorized to…

Assembly Bill
No. 1018
| Introduced by Assembly Member Bauer-Kahan (Coauthors: Assembly Members Aguiar-Curry, Bryan, Ortega, and Ward) (Coauthor: Senator Padilla) |
February 20, 2025 |
An act to add Chapter 24.6 (commencing with Section 22756) to Division 8 of the Business and Professions Code, to add Section 51.1.1 to the Civil Code, and to add Article 3 (commencing with Section 12959) to Chapter 6 of Part 2.8 of Division 3 of Title 2 of the Government Code, relating to artificial intelligence.
LEGISLATIVE COUNSEL'S DIGEST
AB 1018, as amended, Bauer-Kahan. Automated decision systems.
The California Fair Employment and Housing Act establishes the Civil Rights Department within the Business, Consumer Services, and Housing Agency and requires the department to, among other things, bring civil actions to enforce the act.
Existing law requires, on or before September 1, 2024, the Department of Technology to conduct, in coordination with other interagency bodies as it deems appropriate, a comprehensive inventory of all high-risk automated decision systems that have been proposed for use, development, or procurement by, or are being used, developed, or procured by, any state agency.
This bill would generally regulate the development and deployment of an automated decision system (ADS) used to make consequential decisions, as defined. The bill would define “automated decision system” to mean a computational process derived from machine learning, statistical modeling, data analytics, or artificial intelligence that issues simplified output, including a score, classification, or recommendation, that is designed or used to assist or replace human discretionary decisionmaking and materially impacts natural persons.
This bill would require a developer of a covered ADS, as defined, to take certain actions, including providing a potential deployer instructions explaining how the covered ADS should be used by the deployer to make or facilitate a consequential decision.
This bill would require a deployer of a covered ADS to take certain actions, including provide certain disclosures to a subject of a consequential decision made or facilitated by the covered ADS that results in an adverse outcome, as defined, and provide the subject with an opportunity to appeal the outcome of the consequential decision, as prescribed.
This bill would authorize certain public entities, including the Attorney General, General to bring a specified civil action for noncompliance.
