How to Verify a Hazardous Substance Removal Contractor (HAZ) in California

California requires all contractors performing hazardous substance removal work valued at $500+ to hold a valid CSLB HAZ license. Of the 1,871 licensed hazardous substance removal contractors in the state, 97% currently hold active licenses and 12.9% 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 Hazardous Substance Removal Contractors

  • Verify the contractor license is active and in good standing
  • Request proof of insurance and bonding
  • Get at least 3 written quotes before selecting a contractor
  • Check federal databases: SAM.gov, OSHA, DOL, and EPA records
  • Confirm bond: California requires $25,000+ contractor bond (SB 607)

Why Verification Matters for Hazardous Substance Removal Work

Under California's "Controlling Employer" doctrine, general contractors face liability for subcontractor safety violations. For hazardous substance removal work specifically, 12.9% 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.
