California
Workers' Comp Exemption

One employee is enough to trigger the general California rule

California’s Division of Workers’ Compensation states the general rule plainly: employers must provide workers’ compensation benefits when they have one or more employees. The rule is not keyed to a four- or five-person threshold. Once a business employs someone who is an employee for California workers’ compensation purposes, coverage is required unless a specific statutory treatment changes that person’s status.

A sole proprietor with no employees is different. The DWC employer FAQ explains that a sole proprietor does not have to buy a policy solely to cover the owner, although the owner can be included by endorsement if coverage is desired. That no-employee situation should not be confused with a company that has employees but wants to exclude one qualifying owner from an otherwise required policy.

The practical starting point is therefore head count plus legal status: identify every person performing services, then determine whether the owner is already outside the employee definition or needs a statutory waiver.

A section 3352 waiver and a CSLB exemption are not the same document

Labor Code section 3352 addresses whether certain owners, officers, directors, general partners, and managing LLC members are excluded from the workers’ compensation employee definition. For the categories that require a waiver, the written waiver is delivered to the corporation’s, partnership’s, or LLC’s workers’ compensation carrier and becomes effective when the carrier receives and accepts it.

The CSLB exemption serves a different purpose. Active contractor licensees ordinarily must keep proof of workers’ compensation insurance or self-insurance on file with the Board. An eligible contractor with no employees can instead certify that no employee coverage is presently required. That filing is about the contractor license record, not about removing a particular officer from an existing policy.

A business can therefore encounter both concepts during its life. For example, a corporation with employees may maintain a workers’ compensation policy and use a qualifying officer waiver with the carrier. A no-employee contractor may instead use the CSLB exemption only while the facts supporting that no-employee status remain true.

For an eligible CSLB licensee, the online exemption flow records the submission in the license database immediately; it is not just a blank PDF download. If the licensee uses the printable 13L-50 route, the contractor must complete and sign the form and submit it to CSLB. Out-of-state licensees with employees covered under another state's laws must submit the signed exemption with their home-state certificate by email or mail, because that case cannot be completed as an online database submission.

California’s owner rules depend on the entity and the owner’s role

Corporate officers and directors who render service for pay are generally employees, but section 3352 provides exclusion paths. A qualifying officer or director who owns at least 10 percent of the corporation’s issued and outstanding stock may execute the written waiver described in the statute. The statute also has a family-ownership alternative for an officer or director with at least 1 percent ownership when a close family member owns at least 10 percent and the officer or director has qualifying health coverage. A sole shareholder officer or director of a private corporation is treated separately by the statute unless coverage has been elected.

For partnerships and LLCs, the relevant owner category is narrower than “any owner.” Section 3352 provides a written waiver path for a general partner and for a managing member of an LLC. The waiver remains effective until the owner withdraws it in writing, so ownership titles and management status matter when deciding whether a particular person fits the exclusion.

This is one reason a generic certificate saying “business owner exempt” is not enough in California. The legal entity, ownership percentage, officer/director title, and management role determine whether the statute’s specific exclusion fits.

Some contractor classifications must carry coverage even with no employees

The CSLB no-employee exemption has important classification limits. Current CSLB guidance says active C-8 Concrete, C-20 Warm-Air Heating, Ventilating and Air-Conditioning, C-22 Asbestos Abatement, C-39 Roofing, and C-61/D-49 Tree Service contractors must maintain workers’ compensation insurance or valid self-insurance even when they have no employees.

A contractor also cannot use the ordinary no-employee exemption when the license is qualified by a Responsible Managing Employee. And if the licensee does employ anyone in a manner subject to California workers’ compensation law, the exemption is no longer valid.

This construction-license rule is separate from the general DWC rule that an employer with one or more employees needs workers’ compensation. It is stricter because it can require proof of coverage for specified contractor classifications before there is any employee to count.

Hiring the first employee can invalidate the contractor exemption immediately

CSLB states that a no-employee exemption on file becomes invalid once the licensee employs anyone in a manner subject to California workers’ compensation law. The Board then requires proof of workers’ compensation coverage, and its current guidance says that proof must reach CSLB headquarters within 90 days of the hire.

That 90-day filing window should not be read as permission to leave the employee uninsured for 90 days. California DWC’s general rule requires the employer to satisfy workers’ compensation requirements when the employee exists; the CSLB period is about getting proof of that coverage into the contractor-license record.

For an owner-managed contractor, the operational control is simple: make workers’ compensation review part of the first-hire checklist before payroll starts, then separately update the CSLB record.

Keep the carrier waiver record and the CSLB license record as two separate evidence trails

For a qualifying officer, director, general partner, or managing LLC member, the important insurance record is the section 3352 waiver and the carrier’s receipt and acceptance. The statute makes timing matter: a waiver is not merely an internal company resolution. Keep the signed waiver, proof of carrier acceptance, the ownership or management facts that made the person eligible, and any later written withdrawal with the workers’ compensation policy records.

For a contractor relying on a no-employee CSLB exemption, the important license record is different. Keep the exemption filing and confirm that the license classification, qualifier arrangement, and workforce still satisfy CSLB’s current requirements. The contractor should not use the carrier waiver as a substitute for a CSLB filing, or use the CSLB exemption as proof that a working owner was excluded from an insured policy.

Set change triggers for both files. A first employee, a new RME, a change into a classification that must carry coverage, a transfer of stock, or a change in who manages an LLC can move the business out of the fact pattern that supported the old document. The practical compliance task is therefore not 'renew the exemption' on a fixed schedule; it is to preserve the right evidence and re-test eligibility whenever the underlying facts change.

What failing to secure coverage actually costs in California

California treats an uninsured period as its own violation, separate from any individual injury claim, and the penalties escalate the longer the gap and the more employees are on payroll during it.

Under Labor Code §3722, once the Director of Industrial Relations finds an employer was uninsured for more than one week in the prior year, it issues a penalty assessment order for the greater of twice the premium the employer would have paid for that period, or $1,500 per employee employed during it. A stop order — which bars using employee labor until coverage is in place — adds a further $1,500 per employee employed when the order is served.

Working through a stop order is a separate misdemeanor, punishable by up to 60 days in county jail, a fine of up to $10,000, or both. If a claim is filed while the employer is found uninsured, the Workers' Compensation Appeals Board can add $2,000 per employee for a non-compensable case or $10,000 per employee for a compensable one.

• Penalty assessment order: greater of 2× the unpaid premium or $1,500 per employee for the uninsured period
• Stop order: additional $1,500 per employee employed when the order is served
• Working through a stop order: misdemeanor, up to 60 days jail and/or a $10,000 fine
• WCAB finding of uninsured status at claim time: $2,000/employee (non-compensable) or $10,000/employee (compensable)
