If you’re planning to work as an electrical contractor in California, securing a C10 license is essential. This license is required to legally bid on and perform electrical work, including installing, altering, or repairing wiring and electrical systems.
At Contractors License Guru, we’ve helped thousands of professionals understand the licensing process and pass the state exams. In this guide, we’ll walk you through the current California C10 license requirements, including experience, paperwork, and what to expect during the application and exam process.
Who Needs a C10 License?
The C10 classification is issued by the California Contractors State License Board (CSLB). It covers all types of electrical contracting, from residential wiring to commercial installations.
You need a C10 license if:
- You’re working on projects that involve electrical systems, wiring, circuit breakers, or lighting systems
- The total value of labor and materials exceeds $500
- You want to legally advertise or contract for electrical work in the state
Unlicensed electrical work in California can result in fines, legal issues, and the inability to collect payment legally. That’s why becoming licensed isn’t just a smart move—it’s a necessary one.
Minimum Requirements for the C10 License
To apply for the C10 license, the CSLB requires that you meet the following qualifications:
- Work Experience
- You must have at least four years of journey-level experience in electrical work within the last ten years.
- Experience must be verified by a qualified individual, such as a licensed contractor, employer, foreman, or union representative.
- This experience must be directly related to the trade—installing and maintaining electrical systems per the National Electrical Code.
- Legal and Age Requirements
- You must be at least 18 years old
- You must have a valid Social Security number or ITIN
- Examination
- You must pass two exams:
- The Law and Business exam, covering contract law, business practices, safety regulations, and labor laws
- The C10 trade exam, which tests your technical knowledge of electrical codes, installations, troubleshooting, and jobsite safety
The C10 Application Process
Once you’ve confirmed that you meet the requirements, you’ll need to:
- Submit an Application to the CSLB for an Original Contractor License
- Pay the application fee
- Wait for approval and your test date
- Pass both exams
- Submit a contractor bond and proof of workers’ compensation insurance (if applicable)
- Pay the license activation fee
From start to finish, the licensing process can take several weeks or months depending on how quickly you complete each step.
