The short answer: if you have even one employee, yes — always. If you’re a one-person shop, it depends on your CSLB classification: C-8, C-20, C-22, C-39 and C-61/D-49 licensees must carry it regardless of employees today. Everyone else can still file a no-employee exemption — but only until January 1, 2028. Check your own situation below.

Who has to carry it right now
Two separate rules stack up here, and mixing them up is where contractors get into trouble.
Rule one: employees. If you have even one employee, California has always required Workers’ Compensation from the moment you hired them. No classification exemption, no grace period, no “they’re part-time.” This is the rule that catches people who treat a helper as a casual favour.
Rule two: your classification. Separately, certain CSLB classifications must carry coverage even with no employees at all:
| Classification | Required regardless of employees since |
|---|---|
| C-39 Roofing | Longstanding — predates SB 216 (B&P §7125) |
| C-8 Concrete | SB 216 phase 1 — January 1, 2023 |
| C-20 HVAC | SB 216 phase 1 — January 1, 2023 |
| C-22 Asbestos abatement | SB 216 phase 1 — January 1, 2023 |
| C-61/D-49 Tree service | SB 216 phase 1 — January 1, 2023 |
| Every other classification | January 1, 2028 |
Phase 1 licensees renewing between January 1 and June 30, 2023 had to show coverage at renewal; those renewing later had a July 1, 2023 filing deadline.
The date moved — and a lot of advice hasn’t caught up
SB 216 originally extended the requirement to every classification on January 1, 2026. Then SB 1455 (Chapter 485, Statutes of 2024) pushed it out two years to January 1, 2028. Plenty of articles, forum posts and even broker pages still cite the old 2026 date, so if you’ve been told you’re already required and you’re not in the list above, check the source’s date.
What is not delayed: SB 1455 also requires the CSLB to build a process by January 1, 2027 — potentially including an audit or other proof — to verify that a licensee claiming the no-employee exemption actually qualifies. So the practical timeline for a one-person shop is: exemption still available now, exemption gets verified from 2027, exemption disappears in 2028.
Why waiting is the expensive option
- A lapse suspends your license automatically. For classifications where coverage is mandatory, no coverage on file means CSLB suspension — and you can’t legally contract while suspended. Any GC who runs your license number will see it.
- Your first policy is your cheapest experience record. Workers’ Comp pricing rewards history. Starting a small policy early builds a record; showing up in 2028 with no history and no X-Mod gives a carrier nothing to credit you for.
- GCs already ask. Most general contractors won’t let a sub on site without a comp certificate regardless of what the law requires, so for a lot of contractors the legal deadline is academic — the commercial deadline already passed.
- Everyone renews at once. A statewide compliance date means a rush. Rates and carrier appetite are better when you’re not part of a stampede.
If you do carry it: check your dual-wage split
California splits sixteen construction trades into a high-wage and a low-wage version of the same classification, divided by an hourly wage threshold. Payroll for workers at or above the threshold is assigned to the lower-rated high-wage code; payroll below it lands in the higher-rated low-wage code — for identical work. The gap is not small: for carpentry, WCIRB’s approved 2026 pure premium rates are $5.51 per $100 of payroll high-wage versus $12.52 low-wage.
Thresholds rose on 13 of the 16 classifications effective September 1, 2026, by $2 to $5 an hour. A wage that cleared the bar last year may not clear it now — which quietly moves payroll into the expensive code at your next audit.

The 16 dual-wage classifications
| Trade | Low-wage code (higher rated) | High-wage code (lower rated) | Threshold from 9/1/2026 |

Thresholds per WCIRB’s approved 2026 dual-wage filing. Wage thresholds and classification assignments are confirmed against your policy and payroll records at quote and at audit — bring us your class codes and we’ll check them.
What we’d actually do for you
If you’re exempt today and planning for 2028, the useful move is not buying a policy this afternoon — it’s knowing what it will cost, what class codes you’ll be rated on, and whether your wages sit on the right side of a dual-wage threshold. That’s a fifteen-minute conversation, and we’ll tell you plainly if waiting is the right call for you. If you’re already required and not covered, that’s more urgent: your license is exposed today.
Either way, tell us your trade and payroll and we’ll come back with real options from A-Rated Carriers, usually within one business day.

Common questions
Do I need Workers’ Comp in California if I have no employees?
It depends on your CSLB classification. C-8 Concrete, C-20 HVAC, C-22 Asbestos Abatement, C-39 Roofing and C-61/D-49 Tree Service licensees must carry Workers’ Compensation regardless of employees today. Every other classification can still file a no-employee exemption certificate with the CSLB — but only until January 1, 2028, when the requirement becomes universal under SB 216.
Wasn’t the deadline January 1, 2026?
It was, until SB 1455 (Chapter 485, Statutes of 2024) delayed it by two years. The all-classifications Workers’ Compensation requirement now takes effect January 1, 2028. A lot of published advice — including plenty still online — has the old 2026 date.
Will I have to prove I qualify for the exemption?
Yes, eventually. SB 1455 requires the CSLB to establish a process by January 1, 2027 — which may include an audit or other proof — to verify that an applicant or licensee without employees is actually eligible for the exemption. Filing an exemption you can’t support is a bad position to be in.
What happens if my Workers’ Comp lapses?
For classifications where coverage is mandatory, a lapse means automatic suspension of your CSLB license — you cannot legally contract while suspended, and GCs checking your license will see it. Reinstatement requires getting coverage back in force and filing proof with the CSLB.
What is a dual-wage classification and why does it matter?
California splits sixteen construction trades into a high-wage and a low-wage version of the same classification, divided by an hourly wage threshold. Payroll for workers paid at or above the threshold goes into the lower-rated high-wage code; payroll below it goes into the higher-rated low-wage code — which can cost more than double for identical work. Thresholds rose on 13 of the 16 classifications effective September 1, 2026, so a wage that cleared the bar last year may not clear it now.
