Before you hire in Mariposa County
- Match the license number on this page to the name on the contract. Licenses belong to a person or a company, not to a crew.
- Confirm the record at CSLB directly. This page mirrors their daily file, but they are the authority.
- Ask for a certificate of insurance separately. CSLB licensing does not verify that a contractor carries liability coverage.
- Get the license number written into the written estimate.
