Before you hire a contractor for any job in California—big or small—it’s critical to verify their license. A valid contractor’s license confirms that the professional meets the experience, insurance, and legal requirements set by the state. Whether you’re a homeowner, business owner, or aspiring contractor yourself, knowing how to complete a California contractor license check helps protect your project and avoid fraud.
At Contractors License Guru, we’ve guided thousands of clients through the licensing process. We also educate the public on how to identify legitimate, state-approved contractors. This guide walks you through the essential steps.
Why Verifying a Contractor’s License Matters
In California, any construction-related project that involves labor and materials must be completed by a licensed contractor. The Contractors State License Board (CSLB) is responsible for regulating these licenses. A quick verification through their database helps ensure:
- The contractor is authorized to perform the work
- Their license is active and in good standing
- There are no major complaints or disciplinary actions
- Bond and insurance obligations are being met
Hiring an unlicensed contractor increases the risk of poor workmanship, legal complications, and potential liabilities. That’s why checking their license is a crucial first step.
How to Perform a California Contractor License Check
- Access the CSLB License Lookup Tool
- Search by Key Details
You can look up a contractor by:
- License number
- Business name
- Personal name (for individual licenses)
Using the license number is typically the fastest and most accurate method.
- Review the License Record
The license entry will show:
- Status (active, expired, suspended)
- Business details and classifications (e.g., B-General Building, C-36 Plumbing)
- Bond and workers’ comp status
- Any enforcement actions on file
If anything seems unclear or inconsistent, Contractors License Guru can help you interpret the information.
What If the License Information Raises Concerns?
If the contractor’s license is not active or the classification doesn’t match the type of work proposed, it’s important to pause and request clarification. A trustworthy contractor should be transparent about their licensing status and willing to provide documentation.
Suspicious or unverifiable licenses can be reported directly to the CSLB. Our team at Contractors License Guru is also available to offer guidance if you’re unsure about a contractor’s credentials.

If you’re a licensed contractor, maintaining your license and keeping your public record accurate is essential. Clients often check your license before hiring, so ensure your name, classification, and business details are current.
