From Apprentice to Electrical Contractor in California: Every Step and Legal Requirement

Why California

California is a big market for electricians. BLS counted 73,310 electricians employed in California in May 2025, with a median annual wage of $76,160 and a mean of $85,860 (BLS OEWS). The state's Employment Development Department projects electrician jobs in California will grow 14.9 percent from 2024 to 2034, from 81,000 to 93,100, with 86,460 total job openings over the decade (EDD projections). The two agencies count differently, so the headcounts don't match. EDD's figure includes self-employed workers.

The two credentials

• Electrician certification is for individuals. It's run by the Labor Commissioner's Electrician Certification Unit, part of the Department of Industrial Relations (DIR), under Labor Code sections 108 to 108.5. These sections used to be numbered 3099 to 3099.4, and a lot of older material still cites the old numbers.
• The C-10 Electrical Contractor license is for businesses. It's issued by the Contractors State License Board (CSLB) under the Business and Professions Code.

The certification law applies only to work for C-10 contractors. In the statute's words, "Certification is required only for those persons who perform work as electricians for contractors licensed as class C-10 electrical contractors." It doesn't apply to work within the scope of a C-7 low voltage or C-45 electric sign license, to "electrical connections under 100 volt-amperes," or to a few other listed situations (Labor Code §108 and §108.2).

One change to watch: AB 1707 would move the Electrician Certification Unit from the Labor Commissioner to CSLB, effective July 1, 2028. It passed the Legislature on August 31, 2026, and as of September 11, 2026 the Governor had not yet acted on it. If it becomes law, the agency changes, but the steps below stay the same until the law says otherwise.

Step 1: Get into the trade legally

Until you're certified, there are two legal ways to do electrical work for a C-10 contractor.

Route 1: A registered apprenticeship. Apprentices in a state-approved program are exempt from certification. The law exempts "registered apprentices performing electrical work as part of an apprenticeship program approved under Chapter 4 of Division 3," a federal Office of Apprenticeship program, or a state apprenticeship program (§108.2(d)). California requires construction apprenticeships to be time-based, with at least 144 hours of related and supplemental instruction and 2,000 hours of on-the-job learning (Labor Code §3078.5). That's a minimum for the whole program. Electrical programs are longer. The Division of Apprenticeship Standards has described one inside wireman program as "a five-year apprenticeship program commitment" that "requires eight thousand hours of on-the-job training" (DAS).

Route 2: Register as an Electrician Trainee. If you're not in an apprenticeship, you can work as an uncertified trainee if three conditions are met (Labor Code §108.4):

1. You're registered with the Labor Commissioner.
2. You've completed or are enrolled in "an approved curriculum of classroom instruction."
3. Your employer attests that you'll be "under the direct supervision of an electrician certified pursuant to Section 108 who is responsible for supervising no more than one uncertified person."

The regulations add the details:

• Classroom hours: you must be "successfully completing at least 150 hours of classroom instruction from an approved Educational Provider each year" (8 CCR §296.2).
• Supervision: it has to be "direct, on-site supervision." One certified electrician can supervise one trainee plus registered apprentices, since apprentices don't count toward the ratio (8 CCR §296.3).
• Cost: "The fee for registering as an Electrician Trainee Registrant is $25.00" (8 CCR §292.0), and "There shall be no fee for annual renewal of registration" (§108.4).
• Renewal: registration is renewed every year, with proof of the classwork and on-the-job hours since the last registration.
• Dropping out: if you stop attending your approved school without finishing, your trainee registration is cancelled (8 CCR §296.2(e)).

Whichever route you take, start keeping your own log of hours by type of work from the first day. The General Electrician certification caps how many hours can count from each type, as the next section explains.

Step 2: Pick your certification and build your hours

California has five electrician certifications. The hours below are work for a C-10 contractor, from 8 CCR §291.1.

The General Electrician certification caps how many hours can come from each type of work, so you need a mix. The caps include 3,000 hours of residential, 6,000 of commercial, 6,000 of industrial, 1,500 of troubleshooting, 1,500 of voice data video, 750 of underground conduit, 600 of finish work, 600 of fire/life safety, and 300 of stock room (8 CCR §291.1). An electrician who has only done residential work can't reach General on those hours alone.

For trainees, the Labor Commissioner's guidance lists the classroom hours expected alongside the work hours: 720 hours of related and supplemental instruction for General Electrician, and 480 hours for Residential, Fire/Life Safety, and Voice Data Video (DLSE).

Step 3: Apply for certification and pass the exam

When you can test. An apprentice "within one year of completion" of their apprenticeship can take the exam and is certified "immediately upon completion of the term of apprenticeship" (§108.2(d)). A trainee who has finished the approved curriculum can also test before the hours are done, and is certified once both are complete (§108.4(k)).

The application. The application has to include "an employment history report from the Social Security Administration" (§108.2). You can redact your Social Security number. The application form names form SSA-7050 for this report. A completed state-approved apprenticeship in the same classification also counts as proof of experience (8 CCR §291.1(a)(1)).

Fees. The application fee is $75.00, and each exam attempt is $100.00 (8 CCR §292.0).

The exam. Starting with exams taken on or after June 1, 2026, the certification exam is administered by CPS HR Consulting and scheduled through Pearson VUE (DLSE test information). The July 2026 Candidate Information Bulletin says:

• General Electrician: 100 questions, 4 hours and 30 minutes.
• Residential Electrician: 80 questions, 3 hours and 30 minutes.
• The three technician exams: 50 questions each, 2 hours and 15 minutes.
• Passing score: "you must achieve a minimum score of 70 %."
• Reference materials: built into the testing system. "You will not be permitted to bring or access any outside materials."
• Code editions: the references include "NFPA 70 – National Electrical Code, 2023 Edition," NFPA 70E (2024), and the Cal/OSHA Pocket Guide.

Some older DIR pages still list shorter exam times and the previous vendor, PSI. Go by the current bulletin.

Retakes. You can retake as many times as you want for one year after you're found eligible, "so long as there is at least 60 days between each sitting," paying the exam fee each time (8 CCR §291.4).

Step 4: Work as a certified electrician and keep it current

Once you're certified, the trainee supervision rules no longer apply to you.

Renewal. Certification is renewed every three years. To renew, you certify under penalty of perjury that you've completed "32 hours further electrical education from an Educational Provider or from a state or federally approved apprenticeship program relevant to the type of certification" and that you've "worked in the industry 2000 hours within the previous three years" (8 CCR §291.5). The renewal fee is $100.00 (8 CCR §292.0). If you let certification lapse, you have to take the exam again.

Penalties. Enforcement under the certification law is aimed mainly at contractors. A C-10 contractor who "willfully employs one or more uncertified persons to perform work as electricians," or who fails to supervise trainees or apprentices properly, faces disciplinary action against the contractor license (§108.2(h)). Anyone who claims to be certified when they aren't is barred from taking the test or registering as a trainee "for a period of seven (7) years" (8 CCR §294.0).

If you're coming from another state

California has no reciprocity for electrician certification. Your out-of-state license can make you eligible to test, but you still have to pass the California exam. If you hold an electrician license in another state with comparable experience requirements, the state "may deem the applicant to have the required experience for certification" (8 CCR §291.1(b)). The Labor Commissioner's FAQ says "out of state electricians need to be certified before they can start working in California, there is no grace period" (DLSE FAQ).

Military experience and work for a C-7 low voltage contractor can also be submitted for credit toward the required hours (8 CCR §291.1(c)).

For the C-10 license, CSLB counts experience as "an out-of-state licensed contractor" toward the experience requirement (CSLB).

Step 5: Qualify for the C-10 license

The C-10 is CSLB's electrical contractor classification. CSLB defines it this way: "An electrical contractor places, installs, erects or connects any electrical wires, fixtures, appliances, apparatus, raceways, conduits, solar photovoltaic cells or any part thereof, which generate, transmit, transform or utilize electrical energy in any form or for any purpose" (CSLB). An amendment adding battery energy storage systems to that wording was approved in 2024 but has been "temporarily stayed by court order" (CSLB).

Experience. You need, "within the last 10 years immediately preceding the filing of the application, not less than four years experience as a journeyman, foreman, supervising employee or contractor in the particular class" (16 CCR §825, printed in CSLB's 2026 License Law & Reference Book). The same regulation defines a journeyman as someone "able to perform the trade without supervision; or one who has completed an apprenticeship program."

Credit for training. CSLB gives "up to three (3) years for technical training, apprenticeship training, or education," and "At least one year must be practical experience." A "Certificate of Completion of Apprenticeship" can count for "A maximum of three (3) years" (CSLB). So a completed electrical apprenticeship can cover up to three of the four years.

Proof. Someone "with firsthand knowledge" has to certify your experience. That can be an employer, contractor, foreman, fellow employee, union representative, building inspector, or several others on CSLB's list.

Who qualifies the license. Every license has a "qualifier," the person whose experience and exams back it. A sole owner can qualify their own license. Corporations and LLCs use a Responsible Managing Officer, Member, Manager, or Employee (B&P §7068). A Responsible Managing Employee has to be "permanently employed" and "actively engaged," which the law defines as "working 32 hours per week, or 80 percent of the total hours per week that the applicant's business is in operation, whichever is less." One person can qualify "no more than three firms in any one-year period," with limited exceptions (B&P §7068.1).

You don't technically need DIR certification to be the qualifier. The law says the C-10 qualifying person "need not also be certified" to do or supervise electrical work for that contractor (§108.2(g)).

Step 6: Apply to CSLB and pass the exams

Application. The application fee is $450 (CSLB fees).

Fingerprints. CSLB requires Live Scan fingerprints (B&P §7069). The processing fee is "$49 ($32 for DOJ and $17 for FBI)" plus the Live Scan site's own fee, and the form has to be returned "within 90 days" (CSLB Live Scan).

Criminal record. Under B&P §480, a licensing board can generally deny a license for a conviction only if it's substantially related to the work and was "within the preceding seven years," with exceptions for serious felonies and certain financial crimes. CSLB says "A license applicant is not required to disclose a criminal conviction on the license application" (CSLB).

Asbestos exam. Every applicant for an initial contractor license must complete an open-book asbestos exam and submit it before the license is issued (B&P §7058.5).

The two exams. You take a Law and Business exam and a C-10 trade exam.

• Time: "You will be given 3-1/2 hours to complete each examination" (CSLB exam FAQ).
• Format: both are closed-book, multiple-choice with four choices per question, and a calculator is provided.
• What the C-10 exam covers (C-10 study guide):
  • Planning and Estimating, 28 percent
  • Rough Wiring, 27 percent
  • Safety, 18 percent
  • Startup, Troubleshooting and Maintenance, 16 percent
  • Finish Wiring and Trim, 11 percent
• Testing vendor: PSI. The fee is $51.43 per exam attempt, you have to wait 21 calendar days between attempts, and your eligibility lasts 18 months (PSI bulletin).

CSLB can waive the exams in some cases, including when you've passed both exams in the same classification within the last five years (CSLB waivers).

Processing time. CSLB posts processing times weekly. As of September 8, 2026, it was processing exam applications received August 24, 2026 (CSLB processing times).

Step 7: Bond, insurance, and the license fee

Once you pass, you'll need the following before CSLB issues the license:

• Contractor bond: $25,000, required since January 1, 2023 (B&P §7071.6). That's the bond amount, not what you pay for it. A surety company charges a premium, which varies.
• Bond of qualifying individual: another $25,000 bond when the qualifier isn't the owner. It isn't required when an RMO owns at least 10 percent of the voting stock, or an LLC qualifier owns at least a 10 percent membership interest (B&P §7071.9).
• If you're an LLC:
  • an employee/worker bond of $100,000 (B&P §7071.6.5)
  • liability insurance of at least $1,000,000 for five or fewer personnel, plus $100,000 for each additional person, up to $5,000,000 (B&P §7071.19)
• Workers' compensation: every California employer must secure workers' compensation coverage (Labor Code §3700).
  • Today, a C-10 contractor with no employees can file an exemption with CSLB.
  • That changes on January 1, 2028. From that date, B&P §7125 limits the exemption to joint ventures with no employees, so solo C-10 contractors will need a policy too. That date comes from SB 1455 (2024), which pushed back the original January 1, 2026 start in SB 216.
• Initial license fee: $200 for a sole owner, or $350 for a partnership, corporation, LLC, or joint venture (CSLB fees).

Step 8: Set up the business

The contractor license is one piece. Running an electrical business in California also means registering with a few other agencies.

Business entity. If you form an LLC:

• The Secretary of State charges $70.00 to form it, plus $20.00 for a Statement of Information "within 90 days of initial registration and every two years thereafter" (SOS).
• The Franchise Tax Board says "Every LLC that is doing business or organized in California must pay an annual tax of $800" (FTB).
• A first-year exemption from that tax applied only to LLCs formed from 2021 through 2023, so it no longer applies.
• Larger LLCs also pay an annual fee based on gross receipts, starting at $900 for $250,000 or more.

Corporations pay an $800 minimum franchise tax, but new corporations don't pay it in their first taxable year (FTB).

Hiring employees. You have to register with the EDD within 15 days of paying more than $100 in wages in a calendar quarter (EDD). New and rehired employees have to be reported "within 20 calendar days of their start-of-work date" (EDD new hire reporting).

Cal/OSHA. Every employer needs a written Injury and Illness Prevention Program (8 CCR §3203). Construction employers also need a written Code of Safe Practices and "toolbox" or "tailgate" safety meetings "at least every 10 working days" (8 CCR §1509). Since July 1, 2024, employers also need a workplace violence prevention plan, with a narrow exemption for workplaces with fewer than 10 employees that aren't open to the public and that comply with the Injury and Illness Prevention Program rule (Labor Code §6401.9). Outdoor work requires a written heat illness prevention plan (8 CCR §3395). The electrical work itself falls under Cal/OSHA's Electrical Safety Orders.

Sales tax. Electrical contractors often sell fixtures as well as installing materials, which affects sales tax. CDTFA says "construction contractors who only furnish and install materials in lump sum contracts are not required to hold a seller's permit," but that "A construction contractor is generally the consumer of materials and the retailer of fixtures." CDTFA treats lighting fixtures as fixtures, so check whether you need a seller's permit (CDTFA Publication 9).

Public works. To bid on or work on public works projects, you must register with DIR (Labor Code §1725.5).

• Fee: $400 per fiscal year, or $800 or $1,200 for two or three years (DIR).
• Exemptions: projects of $25,000 or less for construction work, or $15,000 or less for maintenance.
• Prevailing wages: required on public works over $1,000 (Labor Code §1771).
• Certified payroll: must be sent to the Labor Commissioner electronically, at least monthly (Labor Code §1771.4).

Your city or county may also require a local business license. Check with the city where your business is based.

Step 9: Stay compliant once you're licensed

• Renew every two years. A contractor license expires "two years from the last day of the month in which the license is issued" (B&P §7140). Active renewal is $470 for a C-10 sole owner and $720 for other entities. That includes a $20 fee CSLB collects from C-10 contractors to fund enforcement of the electrician certification law (CSLB fees, B&P §7137). There's no continuing education requirement for the contractor license itself, but your electrician certification still needs its 32 hours every three years.
• Hire legally. Unless one of the law's exemptions applies, everyone doing electrical work for your C-10 business has to be certified, a registered trainee under proper supervision, or a registered apprentice (§108.2).
• Show your license number. It has to appear on "all construction contracts," "subcontracts and calls for bid," and "all forms of advertising" (B&P §7030.5).
• Follow home improvement contract rules. The down payment "shall not exceed one thousand dollars ($1,000) or 10 percent of the contract amount, whichever amount is less" (B&P §7159.5). The contract has to say so in capital letters, along with the other disclosures in B&P §7159.

What happens if you skip the license

Contracting without a license is a misdemeanor in California. A first conviction carries "a fine not exceeding five thousand dollars ($5,000) or by imprisonment in a county jail not exceeding six months, or by both," and penalties go up for repeat convictions (B&P §7028). Since July 1, 2026, CSLB citations for unlicensed activity carry penalties of "not less than fifteen hundred dollars ($1,500) nor more than fifteen thousand dollars ($15,000)" (B&P §7028.7).

There is a small-job exemption, but it's narrow. It covers a job where "the aggregate contract price for labor, materials, and all other items is less than one thousand dollars ($1,000)" and "the work or operation does not require a building permit" (B&P §7048). It doesn't apply if the job is split up to stay under the limit, if you advertise yourself as a contractor, or if you employ someone to help with the work. Most electrical work needs a permit anyway.

Timeline and costs at a glance

At 2,000 hours a year, the 8,000 hours for General Electrician come to four years of full-time work.

Frequently asked questions

Do you need a license to be an electrician in California?

You need state certification, not a license, to do electrical work for a C-10 contractor, unless you're a registered apprentice or a registered electrician trainee under supervision. The license, the C-10, is for running an electrical contracting business.

How many hours do you need to become a certified electrician in California?

General Electrician certification requires 8,000 hours of work for a C-10 contractor, spread across at least two types of work. Residential Electrician requires 4,800 hours.

How long does it take to become an electrician in California?

At 2,000 hours a year of full-time work, the 8,000 hours for General Electrician take four years. Registered apprentices can take the exam in their final year and, if they pass, are certified as soon as they finish the program.

Can I work in California with an electrician license from another state?

Not right away. California has no reciprocity, and out-of-state electricians must pass the California certification exam before working. An out-of-state license can count toward the required experience.

How much does the California certification exam cost, and what's on it?

The application is $75 and each exam attempt is $100. The General Electrician exam has 100 questions in 4 hours and 30 minutes, uses the 2023 National Electrical Code, and requires 70 percent to pass.

What do you need to get a C-10 license?

Four years of journey-level experience within the last 10 years, with up to three years of credit for a completed apprenticeship or training. You also need to pass the Law and Business and C-10 exams, submit fingerprints, and post a $25,000 contractor bond.

How much does a C-10 license cost?

The state fees are $450 to apply, $200 for a sole owner's initial license ($350 for other entities), $51.43 per exam attempt, and $49 for fingerprint processing plus the site fee. You also need the $25,000 bond, which you buy from a surety company.

Can you do small electrical jobs without a license in California?

Only if the total contract price for labor, materials, and everything else is less than $1,000, the work doesn't require a building permit, you don't advertise as a contractor, and you don't employ anyone to help. Contracting without a license outside that exemption is a misdemeanor, with fines up to $5,000 for a first conviction.
