How to Verify a Contractor's License in California
Before hiring a contractor in California, always verify their license status. Here is how:
- Visit the California Contractors State License Board (CSLB) license lookup tool.

What Happens If You Hire an Unlicensed Contractor in California
Hiring an unlicensed contractor in California carries significant risks for both the homeowner and the contractor:
- No consumer protections: State recovery funds and guaranty programs typically only cover work performed by licensed contractors.
- Insurance issues: Your homeowner's insurance may deny claims related to work done by an unlicensed contractor.
- Permit problems: Building permits often require a valid contractor license. Work done without permits can create issues when selling your property.
- Quality concerns: Licensed contractors have demonstrated minimum competency through exams, experience requirements, or both.
- Legal liability: Homeowners may bear greater legal responsibility for injuries or property damage caused during unlicensed work.
- Penalties: In California, unlicensed contracting can result in fines and criminal penalties for the contractor, and the homeowner may lose the ability to enforce the contract.
Reciprocity Agreements
California does not currently have reciprocal contractor licensing agreements with other states. Contractors licensed in other states must apply for a new California license through the standard application process. Some states may credit out-of-state experience toward licensing requirements -- contact the California Contractors State License Board (CSLB) for details.
