If you plan to wire homes, install EV chargers, or bid on commercial tenant improvements in the city, you need an electrical contractors license San Francisco building officials will recognize. That license does not come from City Hall. It comes from the California Contractors State License Board (CSLB), which issues the C-10 Electrical Contractor classification statewide. The city layer sits on top: electrical permits and inspections from the San Francisco Department of Building Inspection (DBI), a Business Registration Certificate from the Office of the Treasurer and Tax Collector, and local rules shaped by seismic risk, historic preservation, and one of the most expensive labor markets in the country.
This guide covers the C-10 scope, qualifications, exams, fees and bonds, the separate state certification your electricians must hold, the RMO and RME route, and what San Francisco adds once your license is active. Figures are current as of 2026; confirm current figures at cslb.ca.gov before you apply.
What the C-10 Electrical Contractor License Covers
The CSLB C-10 classification authorizes a contractor to install, erect, or connect electrical wires, fixtures, appliances, raceways, conduits, solar photovoltaic cells, and any related equipment that generates, transmits, transforms, or uses electrical energy. In San Francisco, that means work such as:
- Service upgrades and panel replacements in Victorian and Edwardian flats
- Full rewires of older buildings with knob-and-tube or cloth-insulated wiring
- EV charger installations in garages, multifamily parking, and commercial lots
- Rooftop solar and battery storage interconnections
- Commercial tenant improvements, lighting retrofits, and low-voltage systems
- Electrical scope inside seismic and soft-story retrofit projects
For a closer look at the classification, see our C-10 electrical license guide. Any job where labor and materials total $1,000 or more requires a licensed contractor; that threshold was raised from $500 by AB 2622, effective January 1, 2025.
Because the license is statewide, the same C-10 that lets you pull permits in San Francisco also lets you work in Oakland, San Jose, or Los Angeles. There is no separate city electrical contractor license. DBI verifies your CSLB number and workers’ compensation status before issuing a permit.
Requirements for an Electrical Contractors License San Francisco Contractors Must Meet
The CSLB applies the same standards to every C-10 applicant in California: experience, two exams, a background check, a bond, and workers’ compensation. Applicants must be at least 18.
Four Years of Journey-Level Experience
You must document at least four years of journey-level or higher experience within the last ten years in the electrical trade. Higher levels include foreman, supervisor, and owner-contractor. Up to three years can be credited for education, apprenticeship, or technical training, but at least one year must be hands-on field work.
Experience must be verified by a qualified certifier with direct knowledge of your work: an employer, a fellow journeyman, a licensed contractor, a union representative, or a building inspector. A completed IBEW apprenticeship with a business representative’s certification carries weight with CSLB reviewers.
Fingerprinting and Background Check
Every applicant and qualifying individual must complete Live Scan fingerprinting for a Department of Justice and FBI background check, at roughly $49 to $75 depending on the provider. A record does not automatically disqualify you, but undisclosed convictions can lead to denial.
The CSLB Exams for C-10 Applicants
Once the CSLB accepts your application, you receive a Notice to Appear for two multiple-choice exams at a PSI testing center in the Bay Area.
Law and Business Exam
This exam covers contracts, business organization, employment law, bonding and insurance, safety, lien rights, public works rules, and CSLB regulations. It is the same for every classification and trips up more trade-skilled applicants than the technical test because the material is unfamiliar. Study the CSLB study guide and the California Contractors License Law and Reference Book closely.
C-10 Electrical Trade Exam
The trade exam tests planning and estimating, rough-in and finish wiring, service and distribution equipment, low-voltage systems, troubleshooting, and safety. It is based on the California Electrical Code, which adopts the National Electrical Code with state amendments. San Francisco has local amendments, but the CSLB exam focuses on the state code.
Waivers are limited to applicants who already hold an active California C-10 or have served as the qualifying individual for a licensed firm in the same classification for five of the last seven years. Most first-time applicants sit for both exams.
Fees, Bond, and Insurance Costs
The table below summarizes the main CSLB costs for a C-10 license as of 2026. Confirm current figures at cslb.ca.gov before submitting payment.
| Item | Amount (2026) | Notes |
|---|---|---|
| Original application fee | $450 | Per classification, non-refundable |
| Initial license fee | $200 sole owner / $350 non-sole owner | Paid after passing exams |
| Live Scan fingerprinting | $49 to $75 | Varies by provider |
| Exam rescheduling | $100 | If you miss or move a test date |
| Contractor License Bond | $25,000 bond | Premium typically $100 to $600 per year |
| LLC Employee/Worker Bond | $100,000 bond | LLC licensees only |
| Bond of Qualifying Individual | $25,000 bond | If qualifier owns less than 10 percent |
| Renewal (every 2 years) | $450 sole owner / $700 non-sole owner | Active status |
| Adding a classification | $230 | For example, adding C-46 Solar |
Every licensee must file a $25,000 Contractor License Bond. You do not deposit the money; you pay a surety an annual premium, typically $100 to $600 depending on credit. Our contractor license bonds guide explains how premiums are set.
Workers’ compensation is mandatory if you have employees, and DBI asks for proof at permit issuance. Licensees with no employees may currently file an exemption, but under SB 216 every licensee must carry workers’ compensation or a certificate of self-insurance starting January 1, 2028. The CSLB does not require general liability insurance, but San Francisco general contractors, property managers, and HOAs almost always demand a certificate with at least $1,000,000 per occurrence.
DIR Electrician Certification for Your Employees
This requirement surprises many new C-10 licensees. The C-10 license covers the business. The individuals who perform electrical work for a C-10 contractor must separately hold a California electrician certification issued by the Department of Industrial Relations (DIR). The program covers general electricians, residential electricians, fire/life safety technicians, voice data video technicians, and non-residential lighting technicians.
- Certification is required for anyone performing work as an electrician for a C-10 contractor, with narrow exceptions for registered apprentices and electrician trainees under direct supervision.
- A general electrician certification requires 8,000 hours of documented experience and a passing DIR exam score; residential certification requires 4,800 hours.
- Certifications renew every three years with continuing education.
- The C-10 licensee must ensure every worker is certified or properly registered; violations bring DIR citations and CSLB discipline.
A DIR certification is not a substitute for the C-10, and the C-10 does not certify you as an electrician. Many owner-operators hold both.
Business Structure and the RMO/RME Route
You can hold a C-10 as a sole proprietor, partnership, corporation, LLC, or joint venture. Corporations and LLCs must name a qualifying individual: a Responsible Managing Officer (RMO) or Responsible Managing Employee (RME) who meets the experience requirement and passes the exams, or who already holds the C-10.
The RMO route is common in San Francisco. A business owner without four years of hands-on electrical work can partner with an experienced electrician who serves as RMO, and an existing C-10 holder can bring a growing firm into compliance quickly. An RMO who owns at least 10 percent of the business avoids the additional $25,000 Bond of Qualifying Individual. An RME must be a bona fide employee working at least 32 hours per week or 80 percent of operating hours, whichever is less. In every case the qualifier must exercise direct supervision and control over construction operations; the CSLB disciplines arrangements that exist only on paper.
San Francisco DBI Electrical Permits and Inspections
With your CSLB number in hand, the city-specific work begins. The San Francisco Department of Building Inspection, at 49 South Van Ness Avenue, issues electrical permits and performs inspections. Nearly all electrical work beyond minor repairs requires a permit, including service changes, new circuits, EV chargers, solar interconnections, and most commercial lighting alterations.
Pulling an Electrical Permit
Many straightforward electrical permits can be obtained over the counter or through DBI’s online portal. Larger scopes, such as a new multifamily service or electrical work inside a full renovation, are filed with the building permit and may route through plan review. DBI verifies an active C-10 license, workers’ compensation coverage or a valid exemption, a current Business Registration Certificate, and owner authorization.
Inspections and Common Local Issues
DBI inspectors schedule rough and final inspections, and the city’s older buildings create recurring corrections: undersized services feeding multiple units, grounding and bonding in pre-1950 buildings, working clearances in cramped garages, and arc-fault and ground-fault protection in remodeled kitchens and bedrooms. The Soft-Story Retrofit Program has generated steady electrical scope in the garage levels of wood-frame buildings.
Exterior equipment such as meter upgrades, rooftop solar racking, and visible conduit on a historic facade may also require San Francisco Planning Department review, so build that time into your schedule and your contract.
San Francisco Business Registration Certificate
Every business operating in San Francisco, including a contractor based elsewhere who performs work in the city, must register with the Office of the Treasurer and Tax Collector and obtain a Business Registration Certificate. Registration is due within 15 days of starting business in the city, the fee scales with gross receipts, and the certificate renews annually. DBI will not issue a permit without it.
The San Francisco Electrical Market in 2026
| Demand Driver | What It Means for a C-10 Contractor |
|---|---|
| Building electrification | Heat pump water heaters, induction ranges, and heat pump HVAC conversions require panel upgrades and new dedicated circuits. |
| EV charging | Garages, multifamily parking, and fleet depots need Level 2 and DC fast charging, often with load management to avoid service upgrades. |
| Solar and storage | Rooftop PV paired with batteries continues to grow and requires close utility interconnection coordination. |
| Seismic and soft-story retrofits | Structural upgrades trigger electrical relocation, new lighting, and code corrections. |
| Older housing stock | Victorians and Edwardians with original wiring generate steady rewire and service-upgrade work. |
San Francisco is one of the most expensive labor markets in the state. Much commercial and public electrical work is performed under IBEW Local 6 agreements, and many general contractors require union signatory subcontractors downtown. Public works require prevailing wage and DIR public works contractor registration at $400 per year. Residential service and small commercial work remain largely open shop. Decide early which market you are building for, because it shapes your pricing, hiring, and bonding capacity.
Application Timeline and Common Delays
The CSLB typically reviews an application within four to eight weeks. From submission to an active license number, plan on three to six months. The most common causes of delay are:
- Experience documentation with dates and duties that do not match across certifiers
- A certifier who cannot be reached or does not qualify
- Failing one exam and waiting to retest
- Missing bond or workers’ compensation paperwork after passing the exams
- Entity paperwork that does not match the application, such as an LLC not yet registered with the Secretary of State
Read our California CSLB guide for an overview of the process, and use our license cost breakdown to budget the first year. Do not work while you wait: unlicensed contracting on any project of $1,000 or more is a misdemeanor, with up to six months in jail and a $5,000 fine for a first offense, and unlicensed contractors lose the right to sue for payment.
Frequently Asked Questions
Is there a separate San Francisco electrical contractor license?
No. The C-10 is issued by the CSLB and is valid statewide. San Francisco requires a Business Registration Certificate and DBI permits, but it does not issue its own contractor license.
Do my employees need their own license?
Employees do not need a CSLB license, but anyone performing electrical work for your C-10 business must hold a DIR electrician certification or be a registered apprentice or trainee under supervision.
Can a general contractor do electrical work in San Francisco?
A Class B General Building contractor may perform electrical work only as part of a project involving two or more unrelated trades. Standalone electrical jobs require a C-10 or a licensed C-10 subcontractor.
How often does the C-10 license renew?
Every two years. The renewal fee is $450 for an active sole owner license and $700 for an active non-sole owner license as of 2026. Your bond and workers’ compensation must remain continuously in force.
Getting Your Electrical Contractors License San Francisco Ready
The path to an electrical contractors license San Francisco inspectors will accept runs through the CSLB: four years of verified experience, two exams, a $25,000 bond, fingerprinting, and workers’ compensation. The city adds DBI permits, Planning review, and business registration, all against a market with strong demand for electrification, EV charging, and solar work and a labor environment where union agreements shape much of the commercial sector.
If you are documenting experience, setting up a corporation or LLC with an RMO or RME, or preparing for the Law and Business and C-10 exams, RMO Services Agency, a Los Angeles-based contractor licensing consultant serving all of California, can review your application before it goes to the CSLB and help you avoid the delays that cost most applicants months.
