What Employers Need to Know in 2025

California is considered the most regulated state for hiring. This can directly affect how employers conduct background checks. The stakes are high: incorrectly running or reviewing a background check in California exposes businesses to fines, lawsuits, compliance risks and reputational damage. Understanding what is legally allowed—and what is off-limits—is essential for any organization hiring in California.

This guide covers how background checks work in California, what employers can legally review, and how to implement compliant hiring procedures.

What Defines a Background Check in California?

A background check in California is a legally governed process used to verify an applicant’s criminal history, identity, and suitability for a specific role. Employers typically screen for risk mitigation purposes, to meet industry-specific compliance rules, and to ensure that employees meet eligibility requirements. California limits how information may be collected, when it may be accessed, and how it may be used when making a hiring decision.

The Legal Framework Governing California Background Checks

California operates under multiple overlapping regulations. Employers must comply with federal law, state law, and local requirements. The main regulations controlling California background checks include the Fair Chance Act, FCRA, AB-2188, and SB-731.

California Fair Chance Act (“Ban The Box”)

California prohibits asking about criminal history during early stages of hiring. An employer may only run a background check after extending a conditional offer. Employers must also conduct an individualized assessment before rescinding an offer based on criminal history. Blanket rules such as “no felony convictions” do not comply with California law.

FCRA – Federal Fair Credit Reporting Act

FCRA requirements apply nationwide but carry added legal attention in California due to the volume of employment litigation in the state. To run a background check, an employer must provide written disclosure, obtain authorization, and follow a defined adverse-action process if a decision may negatively affect the applicant.

AB-2188 – Restricting Adverse Decisions Based on Cannabis Use

Effective as of 2024, AB-2188 restricts employers from rejecting applicants solely because cannabis use on drug tests. However, employers may still test for impairment and safety-sensitive performance. But screening may not penalize lawful, off-duty use.

SB-731 – Expanded Record Sealing

California has broadened its automatic record sealing rules. Certain older convictions, dismissed cases, and non-violent offenses may not appear during standard county-level searches. Employers should not assume that a clean report means no historical record exists; it may mean records have been sealed by law.

What Employers Can Legally Review During a California Background Check

California allows the review of identity, county criminal history, federal criminal records, employment history, education, professional credentials, and motor vehicle reports. However, several categories of information are restricted.

• Employers may not use expunged or sealed records

• Juvenile records, arrests that did not lead to conviction, or outdated conviction history beyond statutory reporting windows.

• Motor vehicle records are widely used for driving, transportation, in-home services, field technicians, and healthcare roles. Employers frequently combine driving history with criminal screening to mitigate liability exposure.

When California Employers Are Permitted to Run a Background Check

A background check may be initiated only after an employer makes a conditional offer. The offer must state that employment is contingent upon a successful background check. Running a background check earlier in the hiring process violates state law and FCRA guidelines.

Once the screening is complete, employers must perform an individualized review. If the employer chooses to take back the offer, they must issue a formal pre-adverse action notice, supply the report, allow time for applicant response, and then issue an adverse-action notice if the decision remains unchanged.

What Typically Shows Up on a California Background Report

Effective background checks in California generally include an SSN trace, state and county criminal searches, nationwide supplemental searches, sex offender registry checks, motor vehicle reports if relevant, and education or employment verification.

Criminal records may reveal sentencing details, probation status, completion status, or pending charges that fall within public reporting boundaries. Healthcare, financial, childcare, elder care, transportation, and government-adjacent roles often require additional verification steps or license validation.

Trustline in California

TrustLine is California’s guardian-level background screening database, administered through the California Department of Social Services. Individuals who work in private homes with children: such as nannies, babysitters, infant caregivers, tutors, private teachers, and doula-type caregivers, must be cleared through TrustLine when agencies or payment subsidies are involved.

TrustLine includes fingerprint-based DOJ and FBI record review, child abuse index screening, and disqualifying offense logic that standard background checks do not capture. In many cases, TrustLine clearance is required before a caregiver begins work, and failure to maintain valid standing can disqualify an individual from being placed. Agencies working with state reimbursement programs or Resource & Referral agencies must verify TrustLine eligibility before referring candidates to families.

Unlike a standard pre-employment background check, TrustLine is reviewed directly by state regulatory authorities rather than an employer, and adjudication decisions are final. Employers cannot override disqualifying outcomes.

For this reason, childcare agencies often pair a traditional background check—which verifies employment history, identity, education, driving history, or sex offender status—with TrustLine authorization. Together, they provide the only legally recognized screening profile for childcare providers working in California home environments, especially when working under state-supported payment programs or agency referral systems.

How Long California Background Checks Take

Turnaround times vary considerably by county, especially due to manual courthouse access requirements. Same-day results are common for federal searches, SSN data, identity validation, and MVR reports. County record searches typically take between two and five business days depending on court access, record volume, and clerk agenda. Large metropolitan areas such as Los Angeles County commonly take longer than average.

Unlike other states that operate centralized criminal record databases, California requires county-level research for the most accurate and up-to-date criminal history.

Nearly every county maintains independent courthouse access rules, processing timelines, and search systems. Most California counties rely on field court researchers who physically retrieve records from public terminal systems or staff-assisted clerks. Counties such as Alameda, Butte, Contra Costa, Fresno, Marin, San Bernardino, Santa Clara, and dozens more fall into this category. The reliance on in-person research is why California’s turnaround times are often slower than other states. Especially when clerks require review for potential matches, or when manual filtering must occur under Fair Chance compliance rules.

Only a small number of counties, most notably Orange and Riverside, offer fully digitized criminal record systems, allowing near-instant result returns when identifiers match cleanly. Los Angeles County operates its own proprietary research system and requires a specialized vendor connection, which is why results in Los Angeles have historically fluctuated in timing depending on clerk staffing and search load. These differences matter: two candidates living only a few miles apart may have drastically different turnaround times depending on which county their record resides in.

Counties with field-only access often reference cases by physical file number, and researchers frequently must access archived microfilm records or request clerical pulls for pre-digital records. Because of this, counties like Sacramento, Kern, San Joaquin, Sonoma, and Merced may require extended delays when older records appear, especially those with sealed, expunged, or partial record retrieval instructions under SB-731.

Most importantly, California prohibits the use of commercial-only databases as final hiring evidence. Employers are required to use county-level verification to confirm correct identity matches, case outcomes, and record status before taking adverse action.

In short, hiring in California requires a county-by-county search approach, not a database-only scan. This is why the most accurate California background checks rely on direct courthouse research—whether digitized, proprietary (as in Los Angeles), or physical copies retrieved by certified court runners—ensuring compliance with reporting windows, sealed record rules, and adjudication requirements.

Common Mistakes Employers Make When Screening in California

Several compliance issues repeatedly expose businesses:

1. Asking about conviction history before extending an offer.

2. Using outdated or database-only results without verified court matching.

3. Denying applicants without providing the proper FCRA notices.

4. Applying a blanket rejection policy for certain record categories.

5. Treating sealed or dismissed records as decision-relevant.

6. Misinterpreting cannabis screening laws.

Any one of these errors can lead to disputes or legal action.

Best Practices for a Legally Compliant Screening Process

A compliant screening framework in California should include the following steps:

1. Present a conditional offer.

2. Provide required disclosure and obtain authorization.

3. Run the appropriate screening package for the role.

4. Conduct an individualized review of results.

5. Document the reasoning behind decisions.

6. Follow the adverse-action structure required under federal law if withdrawing an offer.

Employers should also retain documentation and proof of authorization for litigation defense, insurance audits, and regulatory review.
