Two certifications, one trade: what a California electrician actually needs before signing for their own work

You are already certified. You carry a card from the state that says you are an electrician, you have been running jobs for a contractor for years, and the only thing between you and your own name on the contract is a different piece of paper from a different agency.

That is the part nobody explains properly. In most trades in California the contractor license is the only credential in the story. In electrical there are two, they come from two agencies, they mean different things, and holding one does not get you the other. Your electrician certification says you may do the work. The C-10 says you may sell it.

This page is the C-10 route in California, and it leads with that split, with Title 24 energy documents, and with the field verification change that landed on 1 January 2026, because those are the three things that make this classification different from every other C on the list.

The certification and the license are different animals

Labor Code s.3099 requires electricians who work for a C-10 contractor to be certified by the state, by category, through an examination administered by the Division of Labor Standards Enforcement, with trainees enrolled in an approved program and working under supervision. That is a rule about people doing the work, and it applies to your crew whether or not you own the company.

The C-10 is a Contractors State License Board license under BPC chapter 9. It is a rule about who may contract, bid, advertise and get paid. Under BPC s.7031(a) an unlicensed contractor cannot sue for compensation, and under BPC s.7031(b) the hirer can recover everything already paid. Your certification card does not help you at all in that conversation.

Two consequences for the person going out on their own. You still keep your certification current after you are the owner. And every electrician you hire needs their own, which is a hiring constraint the general trades do not have and which is quietly why good electricians are worth what they cost.

Title 24 is the trade's real workload, and one of its dates just moved

The code in California is Title 24, not the I-Codes, and the energy standards inside it are the part that lands on a C-10 harder than on anyone else. Lighting controls, service and panel work, load calculations, EV supply equipment, heat pump circuits and battery storage all produce compliance paperwork that gates the permit, not just the inspection.

Three families of documents run through a job. The compliance document produced at design says what the building is supposed to be. The installation certificate is signed by the installing contractor, which is you, saying what actually went in. The verification certificate comes from the field verifier who tests it.

The change to know: Title 24 energy field verification moved from HERS to the ECC Program on 1 January 2026, and registered certificates gate permit closeout. If your habit is to hand the general a folder of paperwork at the end and let somebody else sort it out, that habit now sits between the owner and a certificate of occupancy, which puts it between you and your retention.

Then the edition question, which is pure arithmetic and worth knowing cold. Standards take effect 180 days after publication, and the edition in force on a given job is fixed by the permit application date. Two houses on the same street can run on two different rulebooks.

Take two tract homes in Riverside. The permit application on lot 14 goes in on 4 December 2025. The permit application on lot 15 goes in on 8 January 2026. Same builder, same plan, same crew, different date. The edition each one is judged against is the one in force when that application was filed, and the field verification path on the second one is registered under the ECC Program. Getting that wrong on a punch list in month nine is an expensive way to find out, and getting it right is a five second question at bid time: what date did the permit application go in.

Local amendments make it worth asking twice. A city may go beyond the state standards only with express findings filed with the Commission, so the answer is knowable, it is just city by city. And residential standards are frozen to June 2031, which means the residential rules you learn this year are the rules for the rest of the decade. That is unusually stable ground to build a business on. Title 24 and CALGreen for contractors is the fuller version.

What the C-10 covers, and the classes that sit against it

The classification family in 16 CCR 832 defines each class, and the rule beneath it is that you may not perform work outside the class you hold. The C-10 covers electrical: placing, installing, erecting and connecting electrical wires, fixtures, appliances, apparatus and raceways that generate, transmit, transform or use electrical energy.

It is the widest specialty classification in the state by the range of work it touches, which is exactly why the boundaries get tested. Low voltage communication, data, sound and alarm systems as a stand-alone scope reads as C-7. Solar photovoltaic sits in C-46. The mechanical side of a heat pump belongs to C-20. Fire alarm work interacts with C-16. Electric signs are C-45.

Most working C-10 contractors end up holding one more class, and the choice tells you what business they are actually in. The C-7 low voltage route is the service and tenant improvement answer. The C-46 solar route is the residential retrofit answer. The C-20 HVAC route is the electrification answer, and it is where the heat pump and panel upgrade work is going. Each added class carries its own trade exam and its own certified experience.

If what you want is to take whole projects and sub out the rest, that is a B. A general building contractor taking a prime contract needs at least two unrelated building trades or crafts under BPC s.7057(a). An electrician who wants to run accessory dwelling units end to end is looking at a B alongside the C-10, not instead of it.

Four years at journey level, and an exam that is not the code test you already passed

CSLB wants four years of journey-level experience within the last ten under 16 CCR 825, with education worth up to three years of credit. Journey-level counts as journeyman, foreman, supervising employee or contractor. For an electrician that maps cleanly onto the years since you were certified, which makes this class one of the easier ones to document, and the certification history helps you show it. What CSLB counts as experience has the certifier list and what the form asks for.

The C-10 trade exam is closed book, multiple choice, at a PSI test center, and it sits alongside the Law and Business exam that every applicant takes. Both are calibrated per version rather than run to a fixed pass percentage. The trap for certified electricians is assuming it is another code exam. It is not. It carries load calculation, plan reading, estimating and job planning, and the Law and Business exam covers contracts, lien law, employment and safety, which is the half most working electricians have never had to study. The two exams and what each one tests is the study map.

The money to open the doors is one paragraph: $450 for the original application, $200 to issue as a sole owner or $350 for any other structure, and a $25,000 contractor license bond under BPC s.7071.6. An LLC carries an additional $100,000 employee and worker bond under BPC s.7071.6.5, which is the single biggest number in the entity decision. Renewal is biennial at $450 or $700 and there is no continuing education. Workers comp goes in before the first employee, because the license is suspended by operation of law on the day cover lapses, with no warning and no grace period. The full application sequence, the bond and the qualifier and LLC against sole proprietor in California cover the rest.

Where the electrical work is

Electrical shows up on almost every permit, which means the permit record is your bid list. Building permits published by Los Angeles, San Francisco, San Diego and Sacramento name the project, the address and often the general. Caltrans advertisements carry highway lighting, signals and electrical systems on state work. CEQAnet filings surface a project at environmental review, frequently a year or more before tender, which is when a general is still assembling a bid list rather than closing one.

Public work is a serious lane for a C-10 because so much of it is institutional. Prevailing wages apply on public works over $1,000, you and every listed subcontractor must be registered with DIR to bid, registration renews on July 1, and certified payroll is submitted electronically at least monthly. On the bid itself, subcontractors above one-half of one percent of the total bid must be named, which on most jobs means the electrical sub is named, so getting onto a general's list early is worth real money. DIR registration and certified payroll and where work is starting in California are the next two pages.

The next thing to do

Pull the last three jobs you wired for somebody else and find the permit application date on each one. If you cannot, that is the habit to build first, because it is the single question that decides which rulebook your bid is priced against.

On AEC Stack there is no monthly subscription. The platform fee is 2.5 percent of each invoice processed through the platform, so the quoting and the invoicing earn their keep on work that gets paid.

Open a working business file, put a real job in it, and see the quote, the change order and the invoice run end to end before you send CSLB the $450.
