How to Verify a Electrical Contractor (C10) in California

California requires all contractors performing electrical work valued at $500+ to hold a valid CSLB C10 license. Of the 29,307 licensed electrical contractors in the state, 96% currently hold active licenses and 2.8% have at least one federal compliance record.

Manual vetting takes 45+ minutes per contractor and routinely misses violations in databases most people don't know to check. SiteVetter runs CSLB status, SAM.gov debarment, DOL wage violations, OSHA safety citations, and EPA environmental records in seconds—creating a timestamped compliance artifact.

Why Verification Matters for Electrical Work

Under California's "Controlling Employer" doctrine, general contractors face liability for subcontractor safety violations. For electrical work specifically, 2.8% of licensed contractors have federal records that a standard CSLB license check wouldn't reveal.
