Licensed vs. Unlicensed Electrician:
Why Your C-10 License Matters in California

Every week I talk to Temecula homeowners who've had electrical work done — EV chargers installed, outlets added, panels "upgraded" — by someone who turned out to be unlicensed. Sometimes they didn't know. Sometimes they were told the license "wasn't required for small jobs." Here's the honest breakdown of what a California C-10 license actually means and why it matters more than most people realize.

What Does C-10 Licensed Actually Mean?

In California, anyone doing electrical work for compensation must hold a contractor's license issued by the Contractors State License Board (CSLB). For electrical work, that's the C-10 Electrical Contractor classification.

To earn a C-10 license, an applicant must:

• Have at least four years of journeyman-level experience in the electrical trade
• Pass a two-part examination: Law & Business and Trade Knowledge
• Carry an active surety bond (minimum $25,000) protecting clients from incomplete or defective work
• Maintain general liability insurance
• Submit to criminal background review

You can verify any California contractor's license — including ours — directly on the CSLB website. New Ground Electric holds California C-10 License #1153189, which shows the license status, bond, and insurance all active.

What Happens When You Hire Unlicensed?

Hiring an unlicensed electrical contractor isn't just a technical violation — it has real, costly consequences for you as the homeowner.

1. Your Homeowner's Insurance Won't Cover the Work

Most homeowner's insurance policies contain exclusions for damage caused by unpermitted or unlicensed work. If a fire starts in your wall six months after an unlicensed electrician wired a new circuit, your insurer has a valid basis to deny the claim. This isn't hypothetical — insurance companies flag this routinely.

2. The Work Can't Be Permitted

In California, only licensed contractors can pull permits. If your job required a permit (EV charger, panel upgrade, new circuit — most installations do), an unlicensed contractor either skips the permit entirely or uses someone else's license fraudulently. Both leave you with unpermitted work on your property.

3. Inspections Will Fail or Never Happen

Permitted work gets inspected by a city or county building official who verifies the installation meets code. Without a permit, there's no inspection — meaning no independent verification the wiring is safe. Unlicensed contractors often cut corners precisely because they know no one will look.

4. Liability Falls on You as the Homeowner

If someone is injured because of faulty electrical work on your property, you bear liability as the owner of record. A licensed contractor's bond and insurance provide a layer of protection. An unlicensed contractor provides none.

5. Complications at Home Sale

When you list your home, a buyer's inspector will identify unpermitted improvements. Lenders often require remediation before approving financing, which means tearing out and redoing the work — legally this time — at your expense. Work that cost $800 unlicensed can cost $3,000+ to remediate and repermit.

The Most Overlooked Risk: Permits at Home Sale

This scenario plays out regularly in Temecula and Murrieta: a homeowner paid cash for an EV charger or panel upgrade from a "guy who does electrical." Years later, they list the home. The buyer's inspector notes the charger or panel work shows no permit on record. The buyer demands either a price reduction or proof of permitted remediation. The seller is now stuck.

Insurance companies have their own version: a homeowner files a claim after an electrical fire. The adjuster finds the wiring was done without a permit by an unlicensed contractor. The claim is denied — not because the damage isn't real, but because the root cause was unauthorized work. The homeowner pays out of pocket.

Neither scenario is theoretical. They happen. The $200 permit fee and the requirement to use a licensed contractor exist specifically to prevent them.

How to Verify a California Electrician's License

Before any electrical contractor starts work on your home, verify their license on the CSLB website:

1. Go to www.cslb.ca.gov and click "Check a License"
2. Enter the contractor's license number (every licensed contractor can give you this instantly)
3. Confirm the license is Active — not Expired, Suspended, or Revoked
4. Confirm the classification includes C-10 (electrical)
5. Confirm the bond and insurance are current

New Ground Electric's license: C-10 #1153189 — verify here. Active, bonded, insured.

Questions to Ask Before Hiring Any Electrician

These four questions take two minutes and will save you from the scenarios above:

• Are you C-10 licensed in California? Ask for the license number.
• Will you pull permits for this work? Any job that requires a permit should include one.
• Can I see proof of insurance? General liability and workers' comp protect you if something goes wrong.
• Do you provide a written flat-rate quote? Verbal estimates leave you exposed to "surprise" charges after the fact.

A legitimate, licensed electrician will answer yes to all four without hesitation. If any answer is vague, deflecting, or "it depends" — treat that as a red flag.
