A sub's CSLB record says "exempt" from workers' comp: what California GCs should check

Short answer

An exemption on a CSLB record means the licensee signed a statement certifying it has no employees. It isn't a policy and covers no one.
It can't be used by a licensee with employees, a license qualified by a Responsible Managing Employee (RME), or C-8, C-20, C-22, C-39 and C-61/D-49 licensees (CSLB).
Once an exempt sub hires anyone covered by workers' comp, the exemption stops being valid. Employing someone without coverage is cause for discipline, with minimum civil penalties of $10,000 or $20,000 per violation (B&P §7125.4).
If an exempt sub shows up with helpers, stop and ask for a workers' comp policy before they keep working.

What "exempt" means on the record

Every active California license needs one of two things on file with CSLB: a certificate of workers' comp insurance (or a state certification of self-insurance), or a signed exemption certifying that the licensee has no employees (CSLB, workers' compensation requirements). The law behind it is B&P §7125.

So "exempt" is the sub's own statement about its business. CSLB records it. It isn't insurance, and it doesn't cover the sub, its helpers or anyone else on your job. The general picture of comp and subs is in workers' comp and subs; this guide is about the exemption itself.

Who can't claim the exemption

According to CSLB (workers' compensation requirements), a licensee can't use the exemption if:

It employs anyone subject to California's workers' comp laws.
Its license is qualified by a Responsible Managing Employee (RME). An RME is an employee, so the license needs coverage.
It holds a C-8 (concrete), C-20 (HVAC), C-22 (asbestos abatement), C-39 (roofing) or C-61/D-49 (tree service) classification. These must carry workers' comp or self-insurance whether or not they have employees.

If one of those applies and the record still shows an exemption, ask the sub about it before work starts. In some cases §7125 has CSLB remove one of these classifications from a license, rather than suspend the whole license, when coverage isn't received, so check that the class you need is still on the license (§7125(f) and (g)).

When an exempt sub hires someone

CSLB says that once an exempt licensee hires anyone covered by workers' comp, the exemption on file is no longer valid, and the licensee has to get coverage and submit proof, which must reach CSLB headquarters within 90 days of the hire (CSLB).

The law is strict about the gap. Under B&P §7125.4, each of these is cause for discipline:

filing a false exemption,
employing a covered person after filing an exemption, without first filing a certificate of insurance or self-insurance, and
employing a covered person without keeping coverage for them.

The section sets a minimum civil penalty of $10,000 per violation for a sole owner and $20,000 per violation for a partnership, corporation, LLC or tribal business, with additional penalties for later violations, and CSLB can't renew or reinstate the license until a current certificate is filed in the business name.

Recertification at renewal

The exemption isn't filed once and forgotten. At each renewal, a licensee with no employees has to recertify the exemption on the renewal form, and a licensee that now has employees has to check the other box and send a current certificate. CSLB says it won't renew the license if that statement is left blank or proof of coverage is missing (CSLB renewal application). The license expiration date on the record tells you when the sub's next recertification is due.

If coverage lapses

If a licensee that needs workers' comp doesn't get or keep it, the license is suspended automatically, effective on the date coverage lapsed or had to be obtained, whichever is earlier (B&P §7125.2). CSLB says any work done while a license is suspended is considered unlicensed (CSLB). See a license suspended mid-job.

What's changing in 2028

The current version of §7125, the one that allows the no-employee exemption, stays in effect only until January 1, 2028 unless a later law changes that date (§7125(i)). Senate Bill 1455 (2024) set January 1, 2028 for workers' comp to apply to all licensees and required CSLB to create a process to verify exemptions by January 1, 2027 (CSLB summary). As of November 4, 2026, check CSLB's workers' comp page for how that process will work.

Why it matters to the GC

An exempt one-person sub can be fine. The trouble starts when the exemption and the job don't match: a crew shows up, or the scope is roofing or concrete. Someone doing work that needs a contractor's license has to hold a valid license to count as an independent contractor (Labor Code §2750.5), and payments to subs without coverage can come up at your premium audit. See workers' comp audits and subs.

What to do, step by step

Look up the record on CSLB's Instant License Check or Sub Check and save a dated copy.
Check the classification. If the sub holds C-8, C-20, C-22, C-39 or C-61/D-49, an exemption is a red flag.
Ask who will be on your site. If the answer is anyone besides the owner, ask for a workers' comp policy and a certificate from the sub's agent before they start.
Put it in the subcontract. Many GCs require the sub to tell them before bringing any helper and to provide proof of coverage first. Ask your lawyer for wording.
Watch the job. If you see extra workers, pause that sub's work until coverage is in place.
Re-check before each payment, at the sub's renewal date and before your own audit.

Common questions

Does a workers' comp exemption mean the sub is covered?

No. It means the licensee signed a statement certifying it has no employees. It isn't a policy and covers no one.

Which subs can't claim the exemption?

According to CSLB: licensees with employees, licenses qualified by a Responsible Managing Employee, and C-8, C-20, C-22, C-39 and C-61/D-49 licensees, which must carry workers' comp whether or not they have employees.

What happens if an exempt sub hires a helper?

CSLB says the exemption is no longer valid and proof of coverage must reach CSLB within 90 days of the hire. Under B&P §7125.4, employing a covered person without coverage is cause for discipline, with minimum civil penalties of $10,000 (sole owner) or $20,000 (entity) per violation.

How often does a sub confirm its exemption?

At each license renewal. CSLB won't renew a license if the workers' comp recertification is left blank or proof of coverage is missing.

Will the exemption still exist after 2028?

The current version of B&P §7125, which allows it, stays in effect only until January 1, 2028, and SB 1455 (2024) set that date for workers' comp to apply to all licensees. Check CSLB for updates.
