CSLB · California State Certifications & Requirements
Get licensed. Stay licensed.
Everything you need from the Contractors State License Board in one place — apply for a contractor license, register as a Home Improvement Salesperson, attend a free workshop, verify a license, and understand your classification. TAE is also working with licensing partners to help members through the process.
