How to Verify a Swimming Pool Contractor (C53) in California

California requires all contractors performing swimming pool work valued at $500+ to hold a valid CSLB C53 license. Of the 2,981 licensed swimming pool contractors in the state, 96% currently hold active licenses and 1.9% 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.
