How to Verify a Plumbing Contractor (C36) in California

California requires all contractors performing plumbing work valued at $500+ to hold a valid CSLB C36 license. Of the 18,387 licensed plumbing contractors in the state, 95% currently hold active licenses and 2.6% 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.

Verification Checklist for Plumbing Contractors

  • Confirm licensing for your specific plumbing needs (water heaters, gas lines, sewer)
  • Ask about experience with local building codes and inspection requirements
  • Check if they offer emergency service availability
  • Check federal databases: SAM.gov, OSHA, DOL, and EPA records
  • Confirm bond: California requires $25,000+ contractor bond (SB 607)

Why Verification Matters for Plumbing Work

Under California's "Controlling Employer" doctrine, general contractors face liability for subcontractor safety violations. For plumbing work specifically, 2.6% of licensed contractors have federal records that a standard CSLB license check wouldn't reveal. SiteVetter's 5-database check catches what a single-source verification misses.
