Workers' Compensation for California Contractors

If your contractor license is active and you have employees, California requires proof of workers' compensation insurance on file with CSLB. If you have no employees, you file an exemption instead, unless your license is one of five classifications that must carry coverage regardless. (CSLB Get Licensed to Build, p. 32) The rules affect what you submit to get licensed, what you recertify at renewal, and what a mistake costs. This article uses CSLB's Get Licensed to Build and the 2026 License Law book as printed in the editions we reviewed. Confirm current requirements with CSLB, because the law book shows more changes coming.

When you must carry workers' compensation

The guide lists the cases in which an active license needs proof of current, valid coverage: (CSLB Get Licensed to Build, p. 27)

• You hire any employee who lives in California.
• You employ home improvement salespeople.
• Your qualifier is a responsible managing employee (RME).
• Your license includes C-8 (concrete), C-20 (HVAC), C-22 (asbestos), C-39 (roofing) or C-61/D-49 (tree service).

Those five license holders must carry coverage, or a valid self-insurance certification, even with no one on the payroll. (CSLB Get Licensed to Build, p. 32) You prove coverage with a Certificate of Workers' Compensation Insurance, issued by a licensed insurer, or a Certification of Self-Insurance, issued by the Director of Industrial Relations. (License Law Book 2026, B&P §7125)

Example: a roofer working alone still needs coverage on file, because C-39 is on the list. A painter working alone does not, as long as there are no employees or salespeople and the qualifier is the owner.

The exemption certificate for owners with no employees

If you have no employees, you submit an "Exemption from Workers' Compensation" rather than insurance. (CSLB Get Licensed to Build, p. 27) The law says the exemption applies when you have no employees, you file a statement certifying that you do not employ anyone who would make you subject to California's workers' compensation laws, and you do not hold one of the five classifications above. (License Law Book 2026, B&P §7125)

Two limits catch people:

• An RME is an employee, so when one qualifies the license, CSLB turns away an exemption certificate. (CSLB Get Licensed to Build, p. 16)
• An exemption does not carry forward forever. At renewal, an active licensee with an exemption on file must recertify it or provide a current certificate of insurance, and the license is not renewed without one or the other. (License Law Book 2026, B&P §7125.5)

A joint venture with no employees can use the same statement. (License Law Book 2026, B&P §7125) An inactive license needs neither proof of coverage nor an exemption. (CSLB Get Licensed to Build, p. 32)

What happens when you hire after filing the exemption

This is the costly mistake. Filing a false exemption, hiring a covered worker after filing an exemption without first filing proof of coverage, or hiring a worker without maintaining coverage are all causes for discipline. (License Law Book 2026, B&P §7125.4(a)) The civil penalty minimums are:

• $10,000 per violation for a sole owner who employed workers without coverage
• $20,000 per violation for a partnership, corporation, LLC or tribal business licensee
• Additional penalties for later violations, up to $30,000 total per occurrence (License Law Book 2026, B&P §7125.4(a))

Worked example: a sole owner files an exemption, then hires a helper for the summer and never adds coverage. Under the law, that is a minimum $10,000 civil penalty for the violation. (License Law Book 2026, B&P §7125.4(a)) The qualifier who should have prevented it can also be guilty of a misdemeanor, (License Law Book 2026, B&P §7125.4(b)) and CSLB cannot renew or reinstate the license until a valid certificate is on file. (License Law Book 2026, B&P §7125.4(c))

Violating the workers' compensation article is a misdemeanor in its own right, and prosecution has to begin within two years of the offense. (License Law Book 2026, B&P §7126) The same section makes it a misdemeanor for an unlicensed person acting as a contractor to violate Labor Code Section 3700. (License Law Book 2026, B&P §7126)

What to submit, in order

1. Decide whether you have employees, home improvement salespeople, an RME qualifier or one of the five always-covered classifications.
2. If so, have your insurer file a certificate in the business name, or obtain a Certification of Self-Insurance. (License Law Book 2026, B&P §7125)
3. If not, file the exemption statement on CSLB's form before the license is issued, reinstated, reactivated or continued. (License Law Book 2026, B&P §7125)
4. Send everything with your other issuance documents, as the guide recommends, to avoid delays. (CSLB Get Licensed to Build, p. 16)

Willful or deliberate disregard of the workers' compensation laws is itself a cause for disciplinary action. (License Law Book 2026, B&P §7125) A contractor is considered duly licensed during any period in which the registrar must accept a certificate, as long as the licensee has otherwise complied. (License Law Book 2026, B&P §7125.3)

Lapses and suspension

If required coverage lapses, the license is suspended automatically by operation of law, effective when coverage lapses or when it was required to be obtained, whichever is earlier. (License Law Book 2026, B&P §7125.2) You can reinstate at any time by showing proof of compliance. (License Law Book 2026, B&P §7125.2)

A short gap in paperwork is treated more kindly. CSLB accepts a certificate as of the date shown on it if it arrives within 90 days, and reinstates the license retroactively if you are otherwise eligible. (License Law Book 2026, B&P §7125.1) Insurers must report policy details, including any cancellation date, to the registrar. (License Law Book 2026, B&P §7125)

Renewal and what is coming

At renewal, active licensees with a certificate on file, or who must file one, also certify the three workers' compensation classification codes with the highest estimated payroll on the policy. (License Law Book 2026, B&P §7125.6)

Two items deserve a watch list. By January 1, 2027, the board is to set up a process to verify, through an audit or proof, that applicants and licensees without employees qualify for the exemption. (License Law Book 2026, B&P §7125.7) And the law book prints a version of Section 7125 that becomes operative January 1, 2028, in which the exemption in subdivision (b) is worded for a joint venture with no employees. (License Law Book 2026, B&P §7125) The 2026 book shows the current version as repealed that day unless a later law changes it, so check with CSLB before relying on the exemption long term.

Where the exam fits

The Law and Business study guide lists workers' compensation insurance under its Insurance and Liens section.
