FAQ
Common Questions
Why C-10 CSLB Verification Matters
In California, any electrical contractor who works on projects valued at $500 or more in combined labor and materials must hold a valid CSLB (Contractors State License Board) license. For electrical work specifically, that license is the C-10 Electrical Contractor classification. Hiring an unlicensed electrician puts you at serious risk — including failed inspections, voided homeowner's insurance, and personal liability if something goes wrong on the job.
A C-10 license tells you several important things about a contractor. It confirms they passed California's trade and law exams. It also confirms they carry the required contractor's bond. As of 2025, the CSLB bond requirement is $25,000 through December 2025 , per the CSLB's published schedule (source: cslb.ca.gov, verified January 2025). Licensed contractors must also maintain active workers' compensation coverage for their employees. When you ask a contractor for their credentials, request their CSLB license number directly — for example, a valid license will appear in the format CSLB License #1234567 . Confirm that number yourself before work begins.
The CSLB tracks complaint history and disciplinary actions. You can see a contractor's full record before you sign anything. Panel upgrades and service entrance work must comply with California Electrical Code (CEC) Article 230. All electrical installations statewide must also meet California Building Code Title 24, Part 3 , as adopted by the California Building Standards Commission.
Every electrician in the NexaBuilder network is pre-screened against the CSLB database before they ever receive a single lead. We check license status, expiration dates, bond standing, and any public complaints. That vetting step happens automatically and continuously — not just once when a contractor signs up. You get matched only with professionals whose credentials are active and in good standing right now. You can also verify a CSLB license yourself at any time using our step-by-step guide.
