CSLB Workers’ Comp Rules: What’s Actually True in 2026
Only five CSLB classifications must carry workers’ comp insurance regardless of employees: C-8 (Concrete), C-20 (HVAC), C-22 (Asbestos Abatement), C-39 (Roofing), and C-61/D-49 (Tree Service). Every other classification can still file a no-employee exemption certificate. The universal, all-classification mandate that SB 216 originally set for January 1, 2026 was delayed to January 1, 2028 by SB 1455, signed in 2024. If you have read that 2026 is a hard cutoff for every contractor, that information is two years out of date — and a lot of pages on this topic still have not caught up.
This page covers the current law under Business and Professions Code § 7125: who must carry coverage today, how the exemption certificate works, what triggers automatic suspension under § 7125.2, and exactly what changes on the real 2028 date. For the other license-keeping requirement — your $25,000 CSLB bond — see our dedicated bond page. The two are tracked as completely separate compliance systems.
- Who requires it: California licensed contractors, under Business and Professions Code §7125. Workers' comp is tracked separately from the $25,000 CSLB bond.
- Amount: the CSLB license bond is a separate $25,000 requirement.
Who Must Carry Workers’ Comp in California Right Now
Two entirely different legal rules layer on top of each other, and conflating them is the single most common mistake contractors make. The first is Cal. Labor Code § 3700 — the general, statewide rule that applies to every California employer, not just contractors: the moment you have one employee, you must secure workers’ comp coverage through an admitted insurer or qualify as a self-insured employer with the Director of Industrial Relations. This has nothing to do with your CSLB license or classification.
The second rule is CSLB-specific and layered on top of the first: Business and Professions Code § 7125 makes a current WC certificate (or a valid exemption) a condition of keeping your license active — and for five classifications, it requires that certificate even if you have zero employees. Those five are C-8 (Concrete), C-20 (HVAC), C-22 (Asbestos Abatement), C-39 (Roofing), and C-61/D-49 (Tree Service). Every other classification — Class A, Class B, and the remaining C-specialties — can file a no-employee exemption certificate under § 7125(b) instead, at least until the current section’s sunset date.
Put simply: if you have an employee, Labor Code § 3700 already requires coverage no matter what you build. If you do not have an employee, only your CSLB classification determines whether § 7125 still requires it.
Official California Requirements
"Every employer, except the state, shall secure the payment of compensation... by being insured against liability to pay compensation by one or more insurers duly authorized to write compensation insurance in this state, or securing from the Director of Industrial Relations a certificate of consent to self-insure."California Labor Code § 3700 • California Labor Code § 3700
In one of the 5 mandatory classes? Pair your WC certificate with an active $25,000 CSLB bond — both are non-negotiable for your license.

If your classification is not one of the mandatory five and you have no employees, you are not automatically exempt — you must affirmatively file for the exemption, and it does not last forever.
Who Needs a Workers' Comp Certificate vs. an Exemption
Cross-referenced against BPC § 7125's classification subsections and Labor Code § 3700.
| Classification / Situation | WC Required With Zero Employees? | Effective Since | Statute |
|---|---|---|---|
| C-8 — Concrete | Yes — even with zero employees | July 1, 2023 | BPC § 7125(g) |
| C-20 — HVAC (Warm-Air Heating, Ventilating & A/C) | Yes — even with zero employees | July 1, 2023 | BPC § 7125(g) |
| C-22 — Asbestos Abatement | Yes — even with zero employees | July 1, 2023 | BPC § 7125(g) |
| C-39 — Roofing | Yes — even with zero employees | January 1, 2013 | BPC § 7125(f) |
| C-61/D-49 — Tree Service | Yes — even with zero employees | July 1, 2023 | BPC § 7125(g) |
| All other classifications (Class A, Class B, remaining C-specialties) | No — exemption certificate allowed if no employees | Exemption available until January 1, 2028 | BPC § 7125(b) |
| Any classification with 1+ employees in California | Yes — the general rule, statewide | Ongoing since long before SB 216 | Cal. Lab. Code § 3700 |
The July 1, 2023 dates were added by SB 216 (Stats. 2022, Ch. 978). The January 1, 2028 exemption cutoff reflects the delay enacted by SB 1455 (Stats. 2024, Ch. 485), which originally would have arrived January 1, 2026.

Eligible only if: you have no employees subject to California workers’ comp law, your classification is not one of the mandatory five, and your qualifier is not serving as a Responsible Managing Employee (RME). The form certifies your no-employee status under penalty of perjury.
Filing a false exemption certificate — or hiring someone subject to WC law after filing one, without first getting covered — is cause for disciplinary action under BPC § 7125.4, separate from any suspension.
BPC § 7125.5 requires recertification at every renewal cycle: a license cannot renew unless the licensee either recertifies the exemption or provides a current WC certificate. Hired your first employee since your last renewal? You must switch off the exemption before that renewal, not after.
Licensees who do carry insurance must also report their top workers’ comp classification codes by estimated payroll under BPC § 7125.6 — a reporting detail most WC coverage summaries skip entirely.
Automatic Suspension Math: What § 7125.2 Actually Triggers
There is no discretion built into this statute. The suspension is automatic, by operation of law — CSLB does not decide whether to suspend you, only when the suspension is deemed effective.
Official California Requirements
"The failure of a licensee to obtain or maintain workers' compensation insurance coverage, if required under this chapter, shall result in the automatic suspension of the license by operation of law."California Business and Professions Code § 7125.2 • BPC § 7125.2
A workers’ comp suspension is tracked completely independently from a bond suspension under BPC § 7071.6 — see our CSLB license lookup guide for how to tell the two apart on your public record.
Busting the “2026 Deadline” Myth: What SB 1455 Actually Changed
SB 216 is real and its 2023 phase is fully in force. What changed is the date for everyone else — and a lot of contractor-facing content never got the update.
From SB 216 (2022) to the Real 2028 Deadline
Every date below is confirmed against the statute text and the SB 1455 legislative record — not a secondary summary.
SB 216 signed (Sept. 30, 2022)
Universal mandate set for Jan 1, 2026
The bill as chaptered (Stats. 2022, Ch. 978) required every CSLB classification — not just high-risk trades — to carry workers’ comp regardless of employee count starting January 1, 2026.
Phase 1 took effect (July 1, 2023)
5 classes went mandatory
C-8, C-20, C-22, and C-61/D-49 joined C-39 roofing (already mandatory since 2013) on the zero-employee WC requirement. This phase never moved and is fully in force today.
SB 1455 signed (Sept. 2024)
Universal mandate delayed to Jan 1, 2028
Stats. 2024, Ch. 485 extended § 7125’s sunset date from 2026 to 2028 and pushed CSLB’s exemption-verification-system deadline to January 1, 2027 — giving the Board time to build an actual audit process before the mandate goes universal.
Today (August 2026)
Only 5 classes are mandatory
This is the current, correct status: the exemption certificate is still valid for every classification outside the 5 listed above. Any page telling you the deadline already passed is describing the original 2022 plan, not the current law.
January 1, 2028
Universal mandate takes effect
The current § 7125 exemption pathway (subsection (b)) is repealed and a successor § 7125 — already drafted and operative on that date — requires WC or self-insurance for every CSLB classification, employees or not.
Sources: Cal. Bus. & Prof. Code § 7125 (current and 2028-operative versions); SB 216 (Stats. 2022, Ch. 978); SB 1455 (Stats. 2024, Ch. 485)
Official California Requirements
"This section shall remain in effect only until January 1, 2028, and as of that date is repealed, unless a later enacted statute that is enacted before January 1, 2028, deletes or extends that date."California Business and Professions Code § 7125(i) • BPC § 7125(i) — sunset clause
Why this matters for your planning: if you hold a classification outside the mandatory five and you were budgeting to add workers’ comp coverage before January 1, 2026 just to stay compliant, you have roughly two more years before that specific requirement arrives — assuming SB 1455’s 2028 date is not amended again before then. Track this page or CSLB’s own workers’ comp page directly rather than relying on older blog posts still citing the 2022 version of the law.
