The short version

California contractors are licensed by the Contractors State License Board (CSLB).
You can look up any license online at cslb.ca.gov or by calling 800-321-CSLB (2752).
California generally requires a license for projects of $1,000 or more in total, including labor, materials, and all other costs. Some smaller jobs can also require one, so check with CSLB.

How to check a license, step by step

Ask for the license number. California law requires contractors to include their license number in their advertising, and you can ask for it before you sign anything.
Search CSLB's "Check a License" tool. Searching by license number is best. If you do not have it, you can search by business name or contractor name.
Confirm the license is active. Look for a current status, not one that is expired, suspended, or revoked.
Match the name and address. The business name and address of record should match the contractor you are talking to.
Check the classification. Each license lists the type of work it covers. Make sure it fits your project.
Look at the bond and workers' compensation. Licensed contractors must have a $25,000 contractor license bond. A contractor with employees must carry workers' compensation insurance or have an exemption on file.
Look for legal actions. The license record can show disciplinary or legal actions. Read anything listed.

What a license check does not tell you

A license check confirms that a contractor is licensed and in good standing. It does not tell you how good their work is, whether their price is fair, or whether they have time for your project. It also does not replace asking for a certificate of general liability insurance, which the contractor has to provide.

Use the license check as the first step, then look at references, ask for an itemized written estimate, and compare more than one bid.

Be careful with payments

For home improvement contracts, California limits the down payment to 10% of the contract price or $1,000, whichever is less. If a contractor asks for much more up front, treat it as a red flag, and ask CSLB if you are unsure.
