California Workers' Comp Insurance for Electrical Contractors

California requires workers' compensation coverage from any business with one or more employees, with no minimum headcount exemption. A licensed contractor who is a sole proprietor with no employees is a notable exception to the 'no employees, no requirement' rule: since a 2023 law change, CSLB-licensed sole proprietors must either carry a policy or file an annual Certification of Exemption even without employees, in order to keep their license active. See the Division of Workers' Compensation's employer FAQs.

Common codes for this work include 5190 Electrical Wiring Contractor; 9516 Electronic Equipment Installation & Repair; 5606 Construction Executive / Supervisor; 7380 Commercial Drivers & Messengers. California maintains its own classification system (WCIRB) rather than NCCI codes. The codes below are NCCI reference codes; your California classification may carry a different number, and we match it during quoting.

Sole proprietors and general partners are automatically exempt from coverage on themselves (subject to the CSLB licensing exception above), since neither is considered an employee of their own business or partnership under California law. LLC members are typically treated as employees and included in coverage by default; a member holding at least 10% membership interest can exclude themselves through a carrier endorsement, but that exclusion requires an affirmative request rather than happening automatically. Corporate officers are also automatically considered employees and covered by default; an officer can be excluded only by owning at least 10% of issued stock, serving as a director (an officer title alone isn't enough), and executing a written waiver under Insurance Code § 11663, and most carriers cap the number of officer exclusions allowed on a single policy at around four.

Operating without required coverage is a misdemeanor under Labor Code § 3700.5, punishable by up to one year in county jail and/or a fine of at least $10,000. The state can also assess civil penalties up to $100,000, issue a stop order that prohibits the use of employee labor until coverage is obtained (violating a stop order can bring up to 60 days in jail and/or a $10,000 fine), and impose a separate penalty equal to twice the unpaid premium or $1,500 per employee, whichever is greater. If an injury claim reaches the Workers' Compensation Appeals Board, additional penalties of up to $10,000 per employee (compensable claims) or $2,000 per employee (non-compensable claims) can apply, capped at $100,000. An uninsured employer also remains directly responsible for all medical bills and can face a separate civil lawsuit from the injured worker.

Price is driven by payroll in each class code, the California rates filed for those codes, your claims history (experience modification), and underwriting factors such as split between licensed electricians, apprentices, and supervisory staff; how much work is performed on live circuits versus de-energized systems; whether crews handle low-voltage or electronic-systems work alongside wiring. We compare carriers so you can see what you qualify for.

Complete one application and we compare up to 10 carriers in minutes, with the option to purchase online. A Live Certificate is included with your coverage, so proof of coverage is always live and shareable by text or email in seconds.

Not necessarily. When that work is tracked separately from traditional building wiring, it may fall under a related classification for electronic-equipment installation, service, or repair rather than the standard electrical-wiring code.

Both are generally rated under the same electrical classification once they're performing electrical work, since the code is based on the work being done rather than licensing status alone.

No. This coverage is written for contractors with W-2 employees on payroll; owner-only certificate ('ghost') policies are not offered.

Yes. California requires coverage for any business with one or more employees, with no minimum headcount exemption.

Only if the officer owns at least 10% of issued stock, serves as a director, and executes a written waiver under Insurance Code § 11663; an officer title alone isn't enough, and most carriers cap officer exclusions at around four per policy.
