Short answer: if you read that every licensed California contractor needs workers’ compensation insurance by January 1, 2026, that date is out of date. SB 1455 moved it to January 1, 2028. A genuine no-employee C-10 electrical contractor can still file the CSLB exemption today.

The part most write-ups miss is that SB 1455 was not the end of it. A second law landed in 2025, and CSLB has since put a concrete proposal in front of the Legislature. Here is the actual state of play.

The timeline, in four lines

  • Today: a C-10 with no employees can still claim the CSLB workers’ comp exemption.
  • By January 1, 2027: CSLB must establish an evidence-based process for verifying exemptions and report that proposed process to the Legislature.
  • January 1, 2028, under current enacted law: the ordinary no-employee exemption goes away and coverage becomes mandatory regardless of employee status.
  • Possibly: CSLB is pursuing legislation for a narrow, audited exemption for qualifying sole owners after 2028. That is a proposal, not law.

Where the classifications stand

Some classifications already cannot claim a no-employee exemption at all: C-8 (concrete), C-20 (warm-air heating and air conditioning), C-22 (asbestos abatement), C-39 (roofing), and D-49 (tree service). SB 216 added four of those effective July 1, 2023. C-39 roofing was already subject to a mandatory workers’ comp requirement before SB 216, so it is on the list for a different reason. The current statute lists all five together.

C-10 is not among them. Until January 1, 2028, licensees in trades outside that mandatory list can continue to claim the exemption if they genuinely have no employees.

One condition attaches to that exemption and it catches people: once you employ anyone in a manner subject to California workers’ compensation law, the exemption on file stops being valid, and proof of coverage has to reach CSLB within 90 days of the hire.

What SB 1455 changed

SB 1455 was CSLB’s sunset extension bill, signed September 22, 2024 and chaptered as Chapter 485, Statutes of 2024. In CSLB’s own words, it “delays from 2026 to 2028 the workers’ compensation insurance for all licensees requirement.”

What SB 291 added in 2025

This is the law most summaries of this topic still leave out. SB 291 was approved by the Governor on October 7, 2025 and chaptered as Chapter 455, Statutes of 2025.

It amended Business and Professions Code section 7125.7 so the verification process CSLB builds is not a paperwork formality. The board must establish a process that includes “an audit, proof, or other means to obtain evidence” that a licensee without employees is actually eligible for the exemption, and must “report its proposed verification process to the Legislature no later than January 1, 2027.”

Worth being precise about what that means, because it is easy to overstate: the law requires CSLB to have an evidence-based process in place and reported by that date. It does not say every existing exemption gets audited on January 1, 2027.

SB 291 also set penalties that matter if you are casual about helpers. For a licensee found to be employing workers without required coverage, current law 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 subsequent violations up to a total of $30,000 per occurrence.

What January 1, 2028 actually does

It is worth stating this plainly rather than softly. Under the law as presently enacted, the operative 2028 version of B&P section 7125 requires coverage regardless of employee status. The ordinary no-employee exemption a solo C-10 uses today does not narrow on that date, it disappears. The express no-employee exemption that survives is for qualifying joint ventures, and an inactive license does not need a certificate during inactivity.

That is the default outcome if nothing else passes.

The proposal that might change it

CSLB is not simply waiting for 2028. Its board authorized submission of a report to the Legislature on March 19, 2026, responding to the SB 291 requirement, and that report proposes a limited exemption for legitimate sole owners after 2028.

As proposed, a qualifying sole owner would need to be an individual owner without a responsible managing employee or registered home improvement salesperson, work in compatible classifications, acknowledge the coverage requirements and penalties, and submit a business plan demonstrating the factual basis for the exemption. It contemplates a $500 filing and recertification fee recurring every two years at renewal, and a targeted enforcement model auditing roughly five percent of exemptions annually rather than every filing.

The important caveat: this is not law. Current enacted law contains no sole-owner exemption after 2028. CSLB’s own materials note that standing up the proposed enforcement unit requires legislative amendment, and staff are seeking a legislative author to introduce a bill. Plan around what is enacted, and treat the proposal as a live possibility rather than a coming certainty.

Where CSLB actually stands

In 2024, CSLB’s board opposed the delay. It voted to support SB 1455 only if amended to restore the 2026 effective date, and those amendments were not adopted. The board’s concern was public protection; the countervailing concern was administrative, since CSLB would absorb a large volume of policies from licensees who currently file exemption forms.

By 2026 its position is more nuanced than simply wanting everyone covered. The board is now actively proposing a tightly controlled, audited exemption for legitimate sole owners. So the fair reading is not that CSLB wants every solo licensee carrying a policy no matter what. It is that CSLB wants exemptions to be verified rather than self-certified, and it is willing to preserve a pathway for genuine sole owners who can prove they qualify.

What to do about it

  • Do not act on the old January 2026 date. Plenty of broker and industry posts still run it. Confirm current requirements with CSLB directly rather than a secondhand summary, this one included.
  • If you have employees, none of this is new. You already need coverage and always did. The phase-in was never about you.
  • Audit how you classify helpers now. A 1099 does not decide the question. California DIR is explicit that employee versus independent contractor status turns on the legal test and the actual circumstances, not the label. California generally requires coverage once you have even one employee, and the penalties above are minimums.
  • Price coverage before you need it. Knowing what a policy costs your shop turns 2028 into a budget line instead of a scramble.
  • Watch the 2027 milestone and any bill that follows. The verification process and whatever legislation CSLB finds an author for are what determine whether a solo exemption still exists for you in 2028.

The deadline moved by two years, not indefinitely, and the rules around exemptions got stricter in the meantime rather than looser. Time to prepare, not a reason to stop tracking it.

Requirements and deadlines change, and this one has already changed twice. Confirm current details with CSLB before making a coverage decision.
