How do I look up a California contractor license?
Search the business name or license number on this page to see its California license numbers, classification, status and expiration date. Contractor licenses in California are issued by the Contractors State License Board (CSLB); confirm the live record on its official lookup (https://www.cslb.ca.gov/OnlineServices/CheckLicenseII/CheckLicense.aspx).
Can I look up a California contractor license by name?
Yes. Type all or part of the business name: every word must start a word of the name, so "acme plumb" finds "Acme Plumbing & Heating, Inc.".
What does an active license mean in California?
An active license means the state listed the license as current when its records were published. Licenses can expire, be suspended or be renewed afterwards, so always check the agency's live record before signing a contract.
Why is a business I know not listed?
DingDongWork lists trade businesses that hold an active license and have a published address. Individuals' professional licenses and inactive records are not listed, and some trades are licensed by cities or counties rather than the state.
