C36 Plumbing Contractor License Lookup

Use this page when you need a California C36 license lookup, a list of licensed plumbing contractors, or a quick screen before assigning plumbing work to a sub. Each row links to a contractor profile with CSLB status, workers' comp, bond, federal records, and permit checks.

California has 18,869 CSLB C36 license records for plumbing contractors. 94% currently hold active licenses and 2.6% have at least one federal compliance record. SiteVetter checks CSLB status, SAM.gov debarment, DOL wage violations, OSHA safety citations, EPA environmental records, and building permits in seconds.

What to Check for C36 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 Federal Records Matter for Plumbing Work

For plumbing work, 2.6% of licensed contractors have federal records that a standard CSLB license check would not reveal. SiteVetter's 6-source lookup gives GCs a faster way to compare subs before bid award, onboarding, or renewal review.

Data sourced from California Contractors State License Board and federal databases. Updated weekly. For official verification, check directly with CSLB.
