Be compliant for California’s FEHA rules

Overview

California’s FEHA rules on AI in employment

New updates to California’s Fair Employment and Housing Act (FEHA) go into effect on October 1, 2025. These changes introduce direct legal responsibilities for both employers and HR Tech vendors using Automated Decision Systems (ADS) in employment.

Automated Decision Systems or ADS in employment is technology that helps make or influence employment-related decisions, using algorithms or artificial intelligence (AI). These systems are increasingly used in areas such as:

Applications Icon

Screening job applications (e.g., resume parsers or automated filtering tools)

Interview Icon

Interview analysis (e.g., AI-powered video interview scoring)

Hiring Icon

Hiring recommendations

Promotion Icon

Promotion or performance evaluations

Reduction Icon

Termination or workforce reduction tools

Compliance

The rules

These rules are among the most comprehensive state-level AI employment regulations in the US and sets a precedent for how AI in employment is used.

Who the law applies to
An employer using AI or ADS technology in hiring or promotion
A vendor developing AI for employment
A compliance or legal lead managing AI risk
Key requirements - FEHA’s ADS amendments outline specific requirements:
Notice
Candidates and employees must be notified when an ADS tool is used to make employment decisions
Bias testing
Is not mandated, but courts and regulators will treat the quality, scope, and recency of testing as central in deciding liability
Record keeping
All testing results and design documentation must be retained for at least 4 years
Safeguards
Employers and vendors must implement reasonable safeguards to prevent unlawful discrimination
Joint liability
Vendors who provide ADS tools may be held jointly liable with employers for discriminatory outcomes

Reducing risk

Both the buyers and builders of AI tech used in employment decisions are responsible for actively reducing the risk of discrimination. If you're using AI to help with hiring, promotions, or firing - you can’t just assume it’s fair. You have to take reasonable, proactive steps to make sure your system isn't treating people unfairly based on protected characteristics, this includes:

  • Regular bias testing across all protected groups (e.g., by race, gender, age)
  • Keeping clear records of how your AI works and how it's been tested
  • Giving people notice when AI is used to assess them
  • Giving humans the final say - especially in high-stakes decisions
  • Using independent audits (like Warden AI) to verify fairness

Protected Classes

Protected characteristics

FEHA prohibits discrimination across 18 protected classes in California employment law, including:

  1. Race

Frequently Asked Questions

California FEHA AI Rules FAQs

The amended FEHA regulations apply to employers with five or more employees that use automated-decision systems (ADS) in California employment decisions — hiring, promotion, training selection, and more. They also reach the vendors and “agents” acting on an employer's behalf, so both the buyers and builders of employment AI carry responsibility. The rules took effect October 1, 2025.

An ADS is any computational process that makes or assists an employment decision. In practice that includes resume screeners and automated filtering tools, AI-powered video interview scoring, hiring or ranking recommendations, and performance, promotion, or termination tools. If a system meaningfully influences who gets hired, advanced, or let go, FEHA likely treats it as an ADS.

No — FEHA does not mandate a bias audit. But the regulations make the quality, scope, and recency of bias testing central to liability: proactive anti-bias testing can be raised as a defense to a discrimination claim, while the absence of testing can be used as evidence against the employer. Independent bias audits from Warden AI give employers and vendors that defensible, documented record.

At least four years. That covers the data fed into the tool, the outputs it generated such as scores or rankings, the criteria applied to candidates, and the results of any bias testing or evaluation. The amendments also extended general personnel-record retention to four years, up from two.

Yes. The regulations expand the definition of “employer” to include agents and third parties that act on an employer's behalf — including those that develop or deploy an ADS. That means a vendor supplying an employment AI tool can be held jointly liable alongside its client for discriminatory outcomes.

FEHA prohibits employment discrimination across 18 protected classes, including race, color, national origin, ancestry, religion, sex, gender identity and expression, age, disability, medical condition, genetic information, marital status, sexual orientation, and military or veteran status. A meaningful bias evaluation should test outcomes across these groups.

Employers are expected to tell candidates and employees when an ADS is used to make or influence an employment decision, and to provide reasonable accommodations on request. Clear notice, combined with human oversight of high-stakes decisions, is part of the “reasonable safeguards” the rules expect.

Warden AI provides independent bias audits, time-stamped audit trails, and dashboards and reporting aligned to the regulations — documenting the proactive testing and safeguards FEHA expects. Whether you are a vendor testing pre-market or an employer monitoring a live system, Warden AI gives you evidence of fairness you can show regulators, courts, and procurement teams.
