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.

Use cases

✓Sourcing licensed plumbing subs for a project in an unfamiliar market
✓Pulling a complete licensed-only call sheet for a manufacturer launch
