Licensed Electrician in California: How to Verify Before You Hire

Electrical work is one of the most regulated trades in California — and for good reason. Faulty wiring is a leading cause of residential fires nationwide. Before you hire anyone to work on your home's electrical system, California law requires that contractor to hold a valid license, and verifying it takes less than two minutes.

Does California require electricians to be licensed?

Yes. In California, any electrical contractor performing work valued at $500 or more must hold a valid license from the Contractors State License Board (CSLB). The specific classification for electrical work is Class C-10. Performing electrical contracting without this license is a misdemeanor, and repeat violations can be charged as a felony.

It's important to distinguish between two types of electrical licensing in California: the contractor's license (C-10, issued by CSLB) and the individual electrician certification (issued by the California Department of Industrial Relations). For hiring purposes, you're primarily concerned with the C-10 contractor license, which covers the business entity performing the work.

What is a Class C-10 electrical license?

A Class C-10 license is California's specialty contractor classification for electrical work. It authorizes the holder to install, construct, maintain, repair, and alter electrical wiring, fixtures, appliances, and other electrical equipment. To earn this license, applicants must pass both a trade exam and a law and business exam, and document at least four years of journey-level electrical experience.

The C-10 classification covers nearly all residential and commercial electrical work: panel upgrades, outlet and switch installation, EV charger installation, lighting, generators, and more. A handyman or general contractor without a C-10 license cannot legally perform electrical work above the $500 threshold in California.

How do you verify an electrician's license in California?

The CSLB offers a free, real-time license lookup at cslb.ca.gov. You can search by the contractor's name, company name, or license number. The result will show the license classification, current status (active, suspended, expired, or revoked), expiration date, bonding status, and any complaints or disciplinary actions on record.

Always run the lookup the same day you make your hiring decision. License status can change — a license that was valid when the contractor first quoted your job may have lapsed or been suspended by the time work is scheduled to begin.

Ask the contractor to provide their license number before they start any work. Licensed contractors are required by California law to include their license number on all contracts, bids, and advertising. If a contractor refuses or is evasive about their license number, that is a serious warning sign.

What bond and insurance does a California electrician need?

All California licensed contractors, including C-10 electrical contractors, are required to maintain a $25,000 contractor's bond on file with the CSLB. This bond provides a financial backstop if the contractor abandons a project, causes damage, or fails to pay subcontractors or suppliers. You can confirm bond status directly through the CSLB license lookup.

In addition to the required bond, electrical contractors working with employees must carry workers' compensation insurance. Without it, you as the property owner could be held liable for medical costs if a worker is injured on your property. Always ask for proof of both general liability insurance and workers' comp before work begins.

What are the risks of hiring an unlicensed electrician?

The risks of unlicensed electrical work go beyond legal exposure — they are genuinely dangerous. Unlicensed electricians are not required to follow California's electrical code, and their work typically won't pass inspection. Unpermitted electrical work can void your homeowner's insurance policy and create significant problems when you sell the property.

According to the U.S. Fire Administration, electrical fires account for approximately 51,000 home fires each year in the United States. Faulty wiring by unqualified workers is a significant contributing factor. The cost of fixing bad electrical work — or worse, recovering from a fire — far exceeds any money saved by hiring cheap, unlicensed labor.

If you hire an unlicensed contractor and something goes wrong, you also lose access to the CSLB's consumer protection tools, including the Contractors' State License Fund, which can reimburse victims of licensed contractors who cause harm.

What else should you check before hiring an electrician?

Beyond confirming an active C-10 license, review the CSLB record for any disciplinary actions, citations, or civil judgments. A license can be valid while still carrying a history of consumer complaints. Look for patterns — a single resolved complaint is different from multiple unresolved ones.

For larger projects, ask whether the contractor will pull permits. In California, most electrical work requires a permit and inspection by the local building department. A licensed contractor should handle permitting as a matter of course. If they suggest skipping permits to save money, that is a red flag regardless of their license status.
