Why verification matters
Unlicensed plumbing is a leading cause of hidden water damage and failed inspections. A licensed plumber is bonded, insured, and works to code - so a repair does not become a mold claim.

Statewide— How we verify
Where this list comes from
Every listing here holds an active license we pulled from the California Contractors State License Board (CSLB) — the government body that actually issues them — not from self-reported profiles.
We re-check license status against the board weekly and drop listings whose license lapses or is revoked. You can confirm any license number at the source yourself, and our free lookup guides show you exactly how.
Why ContractorRoster
The state board's job ends at the license. Ours starts there.
When you need a licensed plumber in a market you don't know, you end up with a dozen browser tabs open to state websites and no phone numbers to show for it — typically 2 to 4 hours of work. ContractorRoster delivers the complete list in minutes: every active license in your area, enriched with phone, email, and website for over 95% of records.
California: California requires all contractors performing work valued over $500 to hold an active CSLB license. The CSLB registry is one of the most comprehensive in the country, with roughly 280,000 active licenses across all trades.
