California certificate of insurance requirements
California's COI landscape is shaped by aggressive labor-code enforcement, the AB 5 contractor test, and strict judicial interpretation of additional-insured wording. Agencies serving California risks should verify named-entity AI endorsements and confirm WC coverage for every employer-insured.
Auto liability minimums
$15,000 / $30,000 / $5,000 (15/30/5) for personal auto; $750,000 CSL for most commercial; $1M+ for for-hire trucking under CA PUC.
Workers' compensation
Workers' compensation is required for every employer with even one employee. Sole proprietors with no employees are exempt; LLCs and corporations have specific officer-exclusion rules.
State-specific quirks
California aggressively enforces WC requirements; uninsured employers face stop-work orders and substantial penalties. Verify WC presence on every cert for any CA-based insured with employees.
Many service-vendor relationships once classified as 1099 may legally be employees in California. COIs for vendors operating in CA should be verified against the ABC test for misclassification exposure.
California courts strictly construe AI endorsements. Generic “as required by contract” language is frequently challenged; named-entity AI endorsements (CG 20 10 / CG 20 37) are the safer pattern.
Notable industry callouts
- Construction. Per-project aggregate (CG 25 03) widely required by CA general contractors and public works.
- Trucking. CA-only motor carriers require Form E filings with CA DMV in addition to federal MCS-90.
