High-Risk Workers' Comp in California: What Contractors Can Do When Carriers Won't Cover Them
You send in your Workers' Comp application and get a decline. A second carrier comes back with a number far above what you budgeted. Your renewal date is getting closer, your options keep shrinking, and your contractor license depends on keeping coverage in place.
If you run a roofing, tree service, concrete, HVAC, or general construction business, this can happen even when you have done everything you were supposed to do.
Here is the short answer: a decline from one insurer does not mean a California contractor has no path to Workers' Compensation coverage. Carriers have different appetites, a better-prepared submission can change how an underwriter sees the account, and California has an insurer of last resort, the State Compensation Insurance Fund, for employers that private insurers are not willing to cover.
The rest of this article explains why your account may be hard to place, what options actually exist, and what to gather before you talk to a broker.
Why California Contractors Are Feeling Workers' Comp Pressure in 2026
Contractors are not imagining it. The broader cost picture in California Workers' Comp has been moving in one direction.
A September 2026 report from the California Workers' Compensation Institute (CWCI) found that construction had the highest 24-month total losses of the industries it studied: about
$49,947 per indemnity claim for accident year 2023, nearly 57% above the statewide average of roughly
$31,892. The same report ranked the Bay Area second among California regions for average total losses, largely because higher wages lead to higher indemnity (wage replacement) costs.
On top of that, the California Insurance Commissioner approved an average
advisory pure premium rate of $1.65 per $100 of payroll for policies beginning on or after September 1, 2026. That is about 6.6% above the approved September 2025 level. The Department of Insurance pointed to higher medical and medical-legal costs, more projected cumulative trauma claims, and rising claim-adjusting expenses.
Two things are worth being clear about:
- An advisory pure premium rate is not your rate. It is a benchmark for expected claim costs. Insurers file their own rates, and your actual premium depends on your class codes, payroll, claims history, experience modification (if you have one), and the carrier's underwriting. It does not mean every employer's premium goes up 6.6%.
- Construction is not automatically "high risk." Plenty of contractors renew without trouble. But when an industry's claims are expensive, carriers look harder at accounts with difficult classifications, recent losses, or missing information.
Broader industry costs set the backdrop. Insurers still underwrite each contracting business individually, and that is where most placement problems actually start.
What Does "High-Risk" Workers' Comp Actually Mean?
"High risk" is not an official label the State of California puts on your business. In practice, it usually means a particular insurer sees your account as outside its preferred appetite, or believes it has characteristics that make claims more likely or more expensive.
Underwriters typically weigh some combination of:
- The work itself: the trade, the hazard level, and what your crew physically does every day
- Class codes: the WCIRB classifications assigned to your payroll
- Claims history: how many claims (frequency) and how serious they were (severity)
- Payroll and headcount: including how payroll is split across classifications
- Time in business: new ventures with no loss history can be harder to price
- Prior coverage: gaps or lapses in coverage raise questions
- Subcontractor use: whether subs carry their own coverage and you can prove it
- Safety practices: whether you have documented procedures, not just good intentions
- Operational footprint: how many jobsites, how far crews travel, and what equipment they use
No single factor makes an account uninsurable. A contractor with one past claim and a strong explanation can look very different from a contractor with three recent claims and no corrective action. And because every carrier weighs these factors differently, one carrier's "no" is a data point, not a verdict.
Why Some Contractor Trades Are Harder to Place
Underwriting concerns follow the kind of injury a trade can produce. Here is how that typically plays out.
Roofing contractors. Falls from height can cause severe, long-duration injuries. Many carriers limit or avoid roofing classifications entirely, which shrinks the market before your individual account is even reviewed.
Tree service contractors. Work at height, chainsaws, chippers, and heavy equipment combine into high severity potential. Tree work is one of the classifications where the number of willing carriers can be noticeably smaller.
Concrete contractors. Heavy materials, repetitive physical labor, equipment, and active construction-site exposure all factor in, especially when payroll is concentrated in field labor.
HVAC, electrical, and plumbing contractors. Crews move between job sites, work in attics and crawlspaces, lift equipment, and drive between calls. Changing environments make conditions harder for an underwriter to predict.
General contractors and subcontractors. Multiple crews, shifting project conditions, and subcontractor relationships raise questions about who is covered by whom. Payroll that is not split correctly across classifications is a common source of both underwriting friction and painful audits.
Why One Carrier Saying "No" Does Not Mean Everyone Will
Every Workers' Comp insurer decides what kinds of risk it wants to write. That is called carrier appetite, and it varies a lot. One carrier may:
- not write a certain classification at all,
- cap how much roofing or tree work it will take on,
- avoid accounts with a recent severe claim,
- require a minimum or maximum payroll size, or
- simply have a narrow appetite this year.
Another market may look at the same account and see it differently, especially if the submission is complete and the story behind any claims is clearly explained.
This is where a broker earns their keep. No honest broker can guarantee coverage. What a good broker can do is present your account accurately, identify markets that may fit your operation, and make sure underwriters receive the information they need to evaluate the risk rather than declining it for missing details.
What If Standard Workers' Comp Carriers Won't Quote You?
If your current carrier non-renews you or several standard carriers decline, there are generally two paths.
Option 1: Other private or specialty markets
A handful of standard declines does not represent the whole market. The account may need a carrier with a different appetite, a specialty program built for certain trades, or simply a better-organized submission. Sometimes the fix is as practical as correcting a class code that makes the account look more hazardous than it is.
Option 2: California State Compensation Insurance Fund
According to the California Department of Insurance, the State Compensation Insurance Fund (State Fund) is a state-operated entity that writes Workers' Comp on a nonprofit basis. It competes with private insurers for business, and it also operates as the insurer of last resort when private companies are not willing to offer Workers' Compensation coverage.
That makes the State Fund an important backstop for California contractors. It does not mean State Fund is always the cheapest option, or that it should be your first stop when private markets are still available. It is one market among several, with a specific role when others step back. A licensed broker can help you compare it against any private options.
What about "assigned-risk" Workers' Comp in California?
Many contractors search for "assigned-risk Workers' Comp" because other states run assigned-risk pools or plans for employers who cannot buy coverage in the regular market. California handles this differently. Rather than a separate assigned-risk pool, State Fund fills the insurer-of-last-resort role for employers that cannot get coverage from private carriers.

So if someone tells you to "get on the assigned-risk plan" in California, what they usually mean is exploring coverage through the State Fund after private markets have been tried.
What to Give Your Broker If Your Account Is Hard to Place
A thin submission invites a decline. A complete one gives an underwriter a reason to say yes, or at least to quote. Before you call, gather as much of this as you can:
- Current policy declarations page
- Renewal or non-renewal notice
- Accurate payroll estimates, split by type of work
- A description of each employee's actual job duties
- Your current Workers' Comp class codes, if you know them
- Your CSLB license number and classifications
- Loss runs from your current and prior carriers (typically the last three to five years)
- A short written explanation of any major claim
- What you changed after that claim: training, equipment, procedures, personnel
- Your written safety program or safety procedures
- Training records, including OSHA training where relevant
- A list of subcontractors and their current certificates of insurance
- A plain-language description of what your company actually does
- Your work radius and typical job locations
- Major equipment your crews use
- Approximate percentage of work by trade or activity
- Your insurance history, including any gaps in coverage
Loss runs take time to request from carriers, so ask for them early. Waiting until two weeks before expiration is one of the most common reasons hard-to-place contractors end up with fewer choices than they should have had.
Can You Make a Hard-to-Place Account Easier to Insure?
There is no guaranteed way to lower a premium or force a carrier to quote. But there are legitimate ways to improve how your account reads to an underwriter.
Get the classification right. Make sure class codes and payroll splits reflect what your employees actually do. Misclassification can make an account look riskier than it is, or create a large audit bill later.
Tell the claim story. If you had a serious claim, explain what happened, what changed afterward, and what controls you added. Underwriters respond better to a contractor who learned from a loss than to one who leaves the loss runs to speak for themselves.
Document your safety practices. Toolbox talks, PPE requirements, fall protection plans, driver and vehicle policies, and jobsite procedures carry more weight in writing than in conversation.
Keep payroll accurate. Underestimating payroll to lower an upfront premium tends to backfire at audit and can damage trust with the carrier.
Clarify employees versus subcontractors. Unclear 1099 arrangements and uninsured subs create real Workers' Comp complications. Collect certificates and keep them current.
Avoid coverage lapses. A gap in coverage can raise underwriting concerns, and for contractors it can also create a licensing problem.
What Contractors Should Know About CSLB Requirements
Workers' Comp is not optional for most California contractors, which is exactly why placement problems are so stressful. A few key points, current as of this review:
- California employers with employees generally must carry Workers' Compensation coverage.
- According to CSLB, active C-8 Concrete, C-20 HVAC, C-22 Asbestos Abatement, C-39 Roofing, and C-61/D-49 Tree Service contractors must carry Workers' Comp (or a valid certificate of self-insurance) whether or not they have employees.
- Under SB 216 as amended by SB 1455, the requirement is scheduled to extend to all licensees regardless of employees beginning January 1, 2028.
- Letting required coverage lapse can affect your license status.
Notice the overlap: several of the classifications that must carry Workers' Comp regardless of employees are also among the trades carriers find harder to place. That is why a decline can become a licensing problem quickly.

A Realistic Example
The following is an illustrative scenario, not a specific client.
A San Jose HVAC contractor with six field employees receives a non-renewal notice 45 days before expiration. The previous year, a technician hurt his back moving a condenser and was off work for several months. The contractor also holds a C-20 license, so going without coverage is not an option even temporarily.
The first two carriers decline. Reviewing the file, it turns out the submission included only the current year's loss run, no explanation of the injury, and payroll that lumped office staff together with field techs.
Once the payroll is split correctly, the claim is explained (including a new two-person lift policy and a lift-assist cart purchased afterward), and prior loss runs are added, the account is resubmitted to markets with an appetite for HVAC contractors. Whether that produces a private-market quote or a State Fund policy, the contractor is now being evaluated on the full picture instead of a partial one.
When Should You Talk to a Broker?
Do not wait until the week your policy expires. Reach out when:
- a carrier declined your application,
- you received a non-renewal notice,
- your renewal price changed significantly,
- you hired employees or payroll grew substantially,
- you added higher-hazard work or changed trades,
- you had a serious claim,
- your contractor license now requires Workers' Comp, or
- you are struggling to find any carrier willing to quote.
RVIS has worked with Bay Area contractors and businesses for more than 30 years, in English and Spanish. A hard-to-place Workers' Comp account is usually less about finding a magic carrier and more about getting the right information in front of the right markets early enough to have choices.
Frequently Asked Questions
What makes a contractor high risk for Workers' Comp in California?
There is no single factor. Insurers look at the trade and its hazards, class codes, claims frequency and severity, payroll, time in business, coverage history, subcontractor use, and safety practices. A carrier may treat an account as high risk because it falls outside that carrier's appetite, even if another carrier sees it differently.
Can I get Workers' Comp if another carrier declined me?
Often, yes. Carrier appetites vary by classification, account size, and loss history, so one decline does not mean every carrier will decline. A more complete submission, corrected class codes, or a carrier with a different appetite can change the outcome. If private carriers will not offer coverage, State Fund serves as California's insurer of last resort.
Does California have assigned-risk Workers' Comp?
Not in the way some other states do. Instead of a separate assigned-risk pool, California relies on the State Compensation Insurance Fund to act as the insurer of last resort when private insurers are not willing to offer coverage. "Assigned risk" is a common search term, but it is not the formal name of a California program.
What is California State Fund?
State Fund is a state-operated, nonprofit Workers' Comp insurer. It competes with private insurers for business and also serves as the insurer of last resort for California employers that cannot obtain coverage in the private market. It is not automatically the cheapest option, so it is worth comparing against any available private quotes.
Can a claims history make Workers' Comp harder to get?
It can. Underwriters look at how often claims happen and how severe they are. But having a claim does not automatically make you a high risk. A clear explanation of what happened and documented changes made afterward can meaningfully improve how an underwriter views the account.
What documents should I send my broker if I am having trouble getting coverage?
Start with your declarations page, renewal or non-renewal notice, payroll split by type of work, employee job duties, CSLB license details, three to five years of loss runs, an explanation of any major claim, your safety program, and current subcontractor certificates. The more complete the file, the more markets can seriously evaluate it.
Having trouble finding Workers' Comp coverage?
Send RVIS your current policy or renewal information, payroll details, contractor classification, and whatever loss history you have. We will help review what may be making the account difficult to place and walk through the coverage options available to your business.
