High Risk Workers Compensation Insurance California Guide

If you run a roofing company, a tree service, a trucking outfit or a security guard firm, you already know the feeling. You ask for a workers’ comp quote and the answer comes back slow, expensive, or as a flat “no.”

That doesn’t mean you can’t get covered. It means your business sits in the part of the market that carriers call high risk, and that part of the market works differently.

I’m Shalom Samya, a licensed commercial insurance broker based in Tarzana. I’ve spent more than 15 years placing coverage for Los Angeles businesses, and a good share of that work is high risk workers compensation insurance California employers struggle to find on their own. This guide explains what makes you “high risk,” how placement really works in this state, what underwriters want to see, and how to bring your cost down over time.

What “High Risk” Means in California Workers’ Comp

There is no official “high risk” label stamped on your file, and the basic rules of workers comp insurance in California apply to you the same as anyone else. It’s an underwriting judgment. Each carrier decides which businesses fit its appetite and which ones it would rather not write.

When a carrier calls you high risk, it’s usually reacting to one or more of five things: your class code, your claims history, your experience mod, how new your business is, and whether you’ve had coverage lapse or cancel.

Some of those you can’t change. Others you can improve a lot, and faster than most owners expect.

Your class code

California workers’ comp is priced per $100 of payroll based on the WCIRB class code that describes the work your employees do. The WCIRB publishes advisory pure premium rates, and each carrier files its own rates on top of that.

For context, the Insurance Commissioner adopted an average advisory pure premium rate of $1.65 per $100 of payroll effective September 1, 2026, which is an increase over 2025. That is an average across every class. Clerical work sits at a fraction of it. Roofing, framing, tree trimming and similar hazardous classes run many times higher.

Advisory pure premium only covers expected losses and the cost of handling claims. Carriers add their own expenses, so what you actually pay is different. The point is simple: if your class code is hazardous, you start at a higher base rate before anyone looks at your claims.

Your claims history

Carriers look at your loss runs, usually the last three to five years. They care about how many claims you had, how severe they were, whether they’re still open, and whether you’ve fixed whatever caused them.

Frequency often worries underwriters more than one large claim. A single bad fall can happen to anyone. Six or seven small injuries a year tells an underwriter something about how the job site is run.

Your experience mod

Once your premium passes a threshold the WCIRB adjusts annually, you get an experience modification factor, often called the X-Mod. It compares your actual losses to the expected losses for your classes.

A 1.00 mod is average. Above 1.00 is a surcharge on your premium. Below 1.00 is a credit. A high experience mod makes you more expensive everywhere and, past a certain point, takes you out of the appetite of many standard carriers entirely. I cover the mechanics in detail in my guide to the workers’ comp experience mod in California.

New business with no track record

A brand new company has no loss history to prove it runs a safe operation. For a low-hazard office, that rarely matters. For a new roofing or tree company, it often does.

Owners with years of experience in the trade can help themselves here. A résumé showing your background, your prior employer, and your safety training gives the underwriter something to work with.

Lapse, cancellation and payment history

If a prior policy cancelled for non-payment, or you went a stretch without coverage, carriers notice. They see a risk that the premium won’t get paid, and a gap during which any injury fell under California’s uninsured-employer rules.

Audit problems count too. If a prior carrier had trouble completing your payroll audit, or you owe them money from an audit bill, some carriers won’t quote until that’s settled.

Industries That Usually Land in the High-Risk Market

The industries below regularly struggle to get competitive quotes. That doesn’t mean every business in them is hard to place. A clean roofing contractor with a low mod can look better to an underwriter than a messy restaurant.

Workers comp for roofing

Roofing is one of the most hazardous classes in construction because of fall exposure. Many standard carriers simply don’t write it.

Under current law, CSLB requires C-39 roofing contractors to carry workers’ comp regardless of whether they have employees. If your roofing license is active, your workers’ comp has to be too.

Workers comp for tree service

Tree trimming and removal combine height, chainsaws, heavy limbs and equipment. Carriers treat it as a serious exposure.

Since January 1, 2023, D-49 tree service contractors have also been required by CSLB to carry workers’ comp regardless of employees. SB 216 added that requirement along with C-8 concrete, C-20 HVAC and C-22 asbestos abatement.

Workers comp for construction

Framing, concrete, demolition, steel and general construction all carry higher rates than most service industries. The trades vary a lot, and so does carrier appetite.

One date every California contractor should know: under current law, SB 1455 set January 1, 2028 as the date when all licensed contractors must carry workers’ comp regardless of employees, with narrow exceptions. Check CSLB for the latest before you plan around it. If you’re a contractor, my guide to contractor insurance in California covers the rest of your insurance picture.

Workers comp for trucking

Drivers get hurt loading and unloading, climbing in and out of cabs, and in accidents on the road. Long-haul work adds time away from home that complicates claims.

Trucking companies also have a classification risk. Many operators use owner-operators, and California’s ABC test makes it hard to treat drivers as independent contractors. If a carrier decides at audit that your “contractors” are really employees, the premium bill can be large. For the full trucking picture, see my page on trucking business insurance in California.

Workers comp for security guards

Security firms face assaults, long shifts, and turnover that makes training harder to keep consistent. Armed guard operations are usually rated more severely than unarmed ones.

Carriers will also want to know where your guards work. Nightclubs, construction sites, retail stores and office lobbies are all very different exposures.

Other classes that often need specialty placement

• Staffing and labor contractors, especially those placing workers in construction or warehouses
• Demolition and excavation
• Moving and storage
• Commercial cleaning with high-rise window work
• Landscaping with tree work or heavy equipment
• Manufacturing with heavy machinery
• Home health and residential care, where lifting injuries are common

High-Risk Traits and What to Do About Each One

Here is how I break down the most common reasons a business gets labeled high risk, and the practical response to each.

High-risk trait	Why carriers care	What to do
Hazardous class code (roofing, tree, framing, trucking)	Higher expected injury frequency and severity	Confirm your payroll is split correctly across class codes; only the work that belongs in the hazardous class should be rated there
Frequent small claims	Signals weak safety habits on the job	Document what caused them and what changed; adopt a written safety program and training records
One large claim	Can drive your mod up for years	Stay involved in the claim, push for return to work, and ask the carrier to update reserves once the claim stabilizes
High experience mod	Surcharge on every quote, and many carriers won’t write above certain levels	Have your mod worksheet reviewed for errors; manage open claims; work on frequency so the next mod improves
New business with no history	No proof of how you operate	Provide an owner résumé, prior experience, safety training certificates and a written safety plan
Prior cancellation or lapse	Payment risk and possible uninsured period	Explain what happened honestly; consider pay-as-you-go billing so premium follows payroll
Unpaid audit balance	Many carriers won’t quote until it’s settled	Resolve or set up a payment plan with the prior carrier before shopping
Heavy use of 1099 workers or uninsured subs	Audit exposure under the ABC test	Collect certificates of insurance from every sub; review worker classification before renewal

Getting Declined for Workers Comp: What It Actually Means

Getting declined for workers comp is common in hazardous trades, and it’s rarely the end of the road. A declination from one carrier usually just means you’re outside that carrier’s appetite.

Standard carriers write mostly lower-hazard classes with clean loss history. They’re built for the middle of the market. When your business falls outside that middle, the standard carrier’s system says no, often without anyone reading your file closely.

The mistake I see most often is an owner getting two or three declinations online or through a single-carrier agent and assuming nobody will write them. Then they either go without coverage, which is a crime in California, or they accept the first expensive quote without knowing if it’s competitive.

Why going without is never the answer

Under Labor Code §3700, every California employer with one or more employees must carry workers’ comp or be approved by DIR to self-insure. Part-time, seasonal and family employees on payroll count.

Being illegally uninsured is a misdemeanor punishable by a fine of not less than $10,000, up to one year in county jail, or both. The Labor Commissioner can also issue a stop order that shuts down your use of employee labor until you get coverage, with a penalty of $1,500 per employee at the time of the stop order.

If an employee is hurt while you’re uninsured, the penalties get worse, the Uninsured Employers Benefit Trust Fund can pay the worker and then come after you for reimbursement, and the employee can sue you directly. I explain the full picture in what happens if a business has no insurance, but the short version is this: a high premium is always cheaper than being uninsured.

Assigned Risk Workers Compensation Insurance California: The Honest Answer

A lot of business owners search for assigned risk workers compensation insurance California because that’s how it works in many other states. There, a business that can’t find coverage gets assigned to a state pool, and a carrier is required to take it.

California doesn’t have a separate assigned risk pool. What it has instead is the State Compensation Insurance Fund, known as State Fund.

State Fund is a nonprofit, public enterprise fund that acts as the “insurer of last resort” in California. When a business can’t get coverage anywhere else, State Fund is where it typically ends up.

In practice, most businesses searching for assigned risk coverage in California end up in one of two places: State Fund, or a specialty or non-standard private carrier that writes high-risk classes on purpose. A broker can place with both, which matters because you want them competing.

How High-Risk Placement Actually Works

When I work on high risk workers compensation California placements, I’m usually looking at four paths. Each has a place, and which one is best depends on your class, your mod, your payroll and how you want to run your business.

State Fund

State Fund writes a wide range of classes and serves as the backstop for the market. For some high-hazard businesses, it’s the most competitive option available. For others, a private carrier comes in lower.

Don’t assume State Fund is either the cheapest or the most expensive. Quote it alongside everything else.

Specialty and non-standard carriers

Some private carriers focus on hazardous classes. They know roofing, trucking and tree work, and they price accordingly. Some of them also write businesses with higher mods or limited history.

These carriers often come with requirements: loss control visits, safety program documentation, deposit requirements, or monthly reporting. Those aren’t bad things. A carrier that understands your trade may also be more reasonable when a claim comes in.

PEO (professional employer organization)

A PEO can cover your employees under its own master workers’ comp policy through a co-employment arrangement. For some hard-to-place businesses, that opens a door that was closed.

The trade-offs are real. Cost is bundled with payroll and HR services, so it can be hard to see what you’re paying for comp. You give up some control. And you need to understand what happens to your loss history and coverage if you leave the PEO, because stepping back into the open market can take work.

I’m not against PEOs. I just want owners to go in with their eyes open and compare the full cost, not the headline.

Pay-as-you-go billing

Pay-as-you-go is a billing method rather than a separate market, but it matters a lot for high-risk businesses. Premium is calculated from actual payroll each pay cycle through your payroll provider.

That means a smaller deposit up front and fewer audit surprises at the end of the term. For a business with a history of cancellations or cash-flow stress, it can also make carriers more comfortable writing you.

Placement Options Compared

Option	Pros	Cons	Often a fit for
State Fund	Insurer of last resort; writes a broad range of classes; stable presence in California	Not always the lowest price; pricing and service vary by account	Businesses declined elsewhere, or where State Fund simply prices best
Specialty / non-standard carrier	Understands hazardous trades; may accept higher mods or thin history	Higher rates or deposits; may require loss control and safety documentation	Roofing, tree service, trucking, security, demolition
Standard carrier (with credits)	Often the best pricing when you qualify; schedule credits possible	Strict appetite; may decline hazardous classes or high mods	High-hazard businesses with clean history and a mod near or below 1.00
PEO master policy	Can open access when direct markets decline; bundled HR and payroll	Bundled cost is hard to compare; less control; exit can be complicated	Smaller employers who also want HR outsourcing
Pay-as-you-go billing (with any carrier that offers it)	Smaller deposit; premium tracks real payroll; fewer audit bills	Requires a compatible payroll provider; not every carrier offers it	Businesses with seasonal payroll or tight cash flow

What Underwriters Want to See From a High-Risk Business

Underwriters in the high-risk market read submissions more closely than standard carriers do. That’s good news, because it means a well-prepared submission can change the outcome.

Here’s what I put in front of them.

Complete, current loss runs

Loss runs are reports from your prior carriers showing every claim, what was paid, and what’s still reserved. Most underwriters want three to five years.

Request them early. Carriers can take a while to send them, and a submission without loss runs often sits at the bottom of the pile.

A written safety program

Not a template you downloaded and never opened. A real program that matches your work: fall protection for roofers, chainsaw and rigging procedures for tree crews, pre-trip inspections and lifting procedures for truckers, de-escalation and post orders for security.

Underwriters want evidence that it’s used. Training sign-in sheets, toolbox talk logs, equipment inspection records and discipline for violations all help.

A return-to-work program

A return-to-work program brings injured employees back on modified or light duty as soon as their doctor allows. It shortens time on temporary disability, which reduces claim cost.

Temporary disability generally pays two-thirds of average weekly wage within state limits. For injuries in 2026, the weekly range is $264.61 to $1,764.11. Every week an employee is back at work in some capacity is a week that isn’t adding to your claim.

Explanations for claims

For every significant claim, I want a short, honest note: what happened, what you changed, and whether the employee is back at work. An underwriter who sees a big claim with no explanation assumes the worst.

Accurate payroll by class code

High-risk businesses often have mixed operations. A roofing company has roofers, but it may also have an office manager and an estimator. A tree company may have climbers and ground crew doing different work.

If your payroll is split correctly and supported by records, only the payroll that belongs in the hazardous class is rated there. Getting this wrong in either direction causes trouble, either overpaying or getting hit at audit.

Subcontractor controls

California uses the ABC test to decide whether a worker is an employee or an independent contractor. If a worker is misclassified, they’re treated as your employee. If an uninsured subcontractor’s worker is hurt, your business can be treated as the employer.

At audit, carriers can also charge premium on what you paid to uninsured subs. Collect a current certificate of insurance from every subcontractor before they start work, and keep it on file.

High Risk Workers Comp in Los Angeles: Local Realities

Finding high risk workers comp in Los Angeles has its own flavor. LA County has a huge concentration of construction, logistics, security, and service businesses, many of them small and owner-run.

The ports, the warehouse corridors across Southern California, and the constant building activity across the county mean a lot of employers are competing for the same appetite at the same carriers.

Plenty of LA owners and crew leaders are more comfortable in Spanish or Hebrew than in English. I work with clients in English, Hebrew and Spanish, which makes a difference when you’re walking through loss runs or a claim with a crew leader or owner who’d rather talk it through in their own language.

Local knowledge also helps with contracts. General contractors, property managers and large shippers in LA regularly require proof of workers’ comp and a waiver of subrogation before you start a job. A high-risk policy that can’t provide those endorsements can cost you work.

Workers Comp With Prior Claims: How to Present Your History

Finding workers comp with prior claims is mostly about presentation. The claims happened. What you control now is how an underwriter understands them.

Check your loss runs for errors

Loss runs aren’t always right. Common problems include claims listed under the wrong entity, claims that closed but still show large reserves, and duplicate entries.

Anything that looks off is worth questioning with the carrier. An inflated reserve on a closed claim makes your history look worse than it is.

Separate one-offs from patterns

Underwriters distinguish between a random accident and a pattern. If most of your claims came from one job, one piece of equipment, or one employee who’s no longer with you, say so and show what changed.

Show what’s improved since

New safety training, a new site supervisor, new equipment, a revised hiring process, or a return-to-work program started last year are all worth mentioning. The goal is to show that the business the underwriter is pricing today is not the same one that had the claims.

Dealing With a High Experience Mod

A high mod is one of the most expensive problems in workers’ comp because it multiplies your whole premium. Here’s how I approach it.

Review the mod worksheet

The mod is calculated using roughly three years of history, excluding the most recent year. It pulls from payroll and claims data your carriers report to the WCIRB.

Errors happen: wrong payroll, claims charged to the wrong entity, reserves that were never reduced after a claim settled. Those errors can be challenged, and fixing one can move your mod.

Manage open claims actively

Reserves on open claims count in your mod. Stay in contact with the adjuster, push to close claims that are ready to close, and ask for reserve reviews when a claim improves.

Understand the timing

Because the most recent year is excluded, today’s improvements show up in future mods, not next month’s. That’s frustrating, but it also means a bad year eventually drops out of the calculation. A consistent safety effort now pays off on a predictable schedule.

Watch claim frequency

The way experience rating is built, frequent small claims can move your mod meaningfully. Some businesses choose to handle minor first-aid-only incidents within the rules, but never discourage employees from reporting injuries. That’s illegal and it backfires.

How to Lower High-Risk Workers’ Comp Cost Over Time

High-risk workers’ comp isn’t a permanent sentence. The premium formula tells you where to push.

Premium is roughly (payroll ÷ 100) × rate for your class × experience mod, plus or minus carrier schedule credits or debits, plus fees and assessments. Most policies also have a minimum premium. Every piece of that formula has a lever.

Lever 1: Classification

Make sure every employee is in the right class code. Clerical, sales and supervisory payroll that doesn’t belong in a hazardous class shouldn’t be rated there. Keep records that support the split.

Lever 2: Payroll accuracy

Your policy starts with an estimate and gets audited at the end of the term. Underestimate and you get an additional premium bill. Overestimate and you get a refund, but you’ve tied up cash all year. Pay-as-you-go billing solves most of this.

Lever 3: Experience mod

Fewer claims, faster return to work, and closed claims with accurate reserves all improve future mods. This is the biggest long-term lever most high-risk businesses have.

Lever 4: Schedule credits

Carriers can apply credits or debits based on things like safety programs, management experience and the condition of your operations. A strong submission is how you earn credits instead of debits.

Lever 5: Market movement

As your history improves, you move toward markets with better pricing. A business that starts at State Fund or a specialty carrier may qualify for a standard carrier after a few clean years. That only happens if someone keeps shopping it.

For a closer look at how each of these pieces affects price, read my breakdown of workers’ comp cost in California.

Common Mistakes High-Risk Businesses Make

• Letting the policy lapse. If a policy cancels for non-payment, you’re uninsured from that date. Reinstatement is up to the carrier. Any injury during the gap falls under uninsured-employer rules.
• Understating payroll to get a lower quote. It feels like savings until the audit bill arrives, and it damages your credibility with that carrier.
• Classifying employees as 1099 contractors to avoid premium. Under the ABC test, that often doesn’t hold up, and the carrier can charge premium at audit.
• Not collecting certificates from subs. Uninsured subcontractor payroll can be picked up at audit, and their injured workers can become your problem.
• Ignoring open claims. Reserves drive your mod. Nobody else is going to watch them as closely as you should.
• Missing claim deadlines. Give the employee a DWC-1 claim form within one working day after an injury is reported, and send the completed form to your carrier within one working day of receiving it. Report serious injuries, illnesses and deaths to Cal/OSHA within 8 hours.
• Forgetting the poster. The required Notice to Employees must be posted where employees can see it, and new hires need the workers’ comp pamphlet. Posting violations can bring civil penalties of up to $7,000 per violation.
• Shopping only once. The market for high-risk classes changes. The carrier that declined you three years ago might want you today.

Owners, Officers and Exclusions

High-risk businesses sometimes look at excluding owners to reduce premium. California allows it in specific situations.

Corporate officers or directors who own at least 10% of the stock can elect exclusion by written waiver. LLC managing members and general partners can also elect exclusion. Sole shareholder corporations are automatically excluded unless they elect coverage.

Excluding an owner removes their payroll from premium, but it also removes their coverage. In a hazardous trade where the owner is on the roof or in the tree alongside the crew, that’s a serious decision. Remember too that C-39 roofers and D-49 tree service contractors must carry workers’ comp under CSLB rules regardless of employees, so talk it through before you sign anything.

Why a Broker Matters More in the High-Risk Market

In the standard market, a lot of workers’ comp gets bought online. In the high-risk market, that approach usually ends in a string of declinations.

I work with multiple carriers and I can place with State Fund and with private carriers, so I can put your submission in front of the markets that actually write your class. I can also tell you when a PEO makes sense and when it doesn’t.

Just as important is what happens after the policy is bound. High-risk accounts need someone who watches the mod, pushes on open claims, prepares for audits, and re-markets the account as it improves. That ongoing work is where most of the savings come from.

Workers’ comp is also only one piece of your protection. High-risk businesses usually need strong general liability, commercial auto and umbrella coverage too. My guide to commercial insurance in California shows how they fit together, and my main page on California workers’ compensation insurance covers the basics every employer should know.

A Simple Action Plan If You’ve Been Declined

1. Don’t let coverage lapse. If your current policy is ending, start the process at least 60 days ahead if you can.
2. Request loss runs from every carrier you’ve had in the last five years.
3. Pull your current mod worksheet and look for errors in payroll or claims.
4. Write down your payroll by job duty, not just a single total.
5. Gather your safety documentation: written program, training records, equipment inspections.
6. Write a short note on each significant claim explaining what happened and what changed.
7. Collect certificates of insurance from your subcontractors.
8. Talk to a broker who places high-risk comp and can quote State Fund, specialty carriers and PEO options side by side.

Frequently Asked Questions

Does California have an assigned risk pool for workers’ comp?

No. California doesn’t have a separate assigned risk pool like many other states. State Compensation Insurance Fund acts as the insurer of last resort, and specialty carriers also write high-risk classes. A broker can quote both.

What makes a business high risk for workers’ comp?

Usually a combination of a hazardous class code, frequent or severe claims, an experience mod above 1.00, no prior history as a new business, or past cancellations and lapses. Each carrier draws the line differently.

Can I get workers’ comp after being declined?

In most cases, yes. A declination usually means you’re outside one carrier’s appetite. State Fund, specialty carriers and PEOs are all possible paths, and a well-prepared submission improves your odds.

How much does high-risk workers’ comp cost in California?

It varies widely by class code, payroll, experience mod, claims history, location and carrier. Hazardous classes can run many times the statewide average advisory rate of $1.65 per $100 of payroll. I can’t give you a real number without looking at your payroll and history.

How long does a high experience mod last?

The mod uses roughly three years of history, excluding the most recent year. A bad year eventually rolls off, and improvements you make today show up in future mods. Correcting errors in the worksheet can help sooner.

Is a PEO a good option for high-risk workers’ comp?

Sometimes. A PEO can open access when direct markets decline you, but costs are bundled, you give up some control, and leaving can be complicated. Compare the full cost against direct options before you commit.

Do roofers and tree services need workers’ comp with no employees?

Under current CSLB rules, C-39 roofing and D-49 tree service contractors must carry workers’ comp regardless of whether they have employees. Under current law, all licensed contractors face that requirement starting January 1, 2028, with narrow exceptions. Check CSLB for updates.

What happens if I operate without workers’ comp while I look for a policy?

It’s a misdemeanor with fines of at least $10,000 and possible jail time, plus stop orders and per-employee penalties. If someone gets hurt, you can be sued directly and pursued for reimbursement. Keep coverage in place, even if it’s expensive, while you work on a better option.
