California Workers' Comp: A Small Business Guide
California requires workers' comp the day you hire your first employee. Here is what it covers, what it costs, and what to do when someone gets hurt.

In California, the moment you hire your first employee, you are legally required to carry workers' compensation insurance. It doesn't matter if they work part-time. It doesn't matter if they only come in on weekends. One employee triggers the requirement under California Labor Code Section 3700.
Most restaurant and retail owners in Orange County know they're supposed to have it, but not many have thought through what it actually does, what it costs, or what happens when someone gets hurt. This covers all of it.
What Workers' Compensation Is
Workers' compensation is insurance that pays for medical treatment and lost wages when an employee is injured or becomes ill because of their job. If a server at your Anaheim restaurant slips and breaks her wrist, workers' comp covers the emergency room visit, any follow-up treatment, and a portion of her wages while she's out.
For the employee, it is a guaranteed benefit. They don't sue you. They file a claim, and your insurer manages it.
For you, it is protection. In exchange for providing this coverage, California law generally prevents injured employees from suing you directly for workplace injuries. Workers' comp is the exclusive remedy in most situations, which limits your liability exposure significantly.
Who Needs It
Every California employer with at least one employee must carry workers' compensation insurance. That includes part-time workers, seasonal workers, and someone who only works a single shift per week.
The one narrow exception is a sole proprietor with no employees at all. Once you hire your first person, regardless of how many hours they work, the requirement kicks in.
Independent contractors are a common question here. If a worker truly qualifies as an independent contractor, they are not your employee and you're not responsible for their workers' comp coverage. But California's AB5 law uses an extremely strict test for what qualifies as a contractor. If you've been treating someone as a contractor who doesn't meet that standard, you have a coverage gap you may not know about. The California AB5 worker classification guide covers how to evaluate where your workers stand.
What It Covers
Workers' comp provides four categories of benefits.
Medical treatment. Your insurer pays for doctor visits, emergency care, surgery, rehabilitation, and ongoing treatment related to the work injury. The employee does not pay out of pocket for covered treatment.
Temporary disability. If the injury keeps the employee from working during recovery, workers' comp replaces a portion of their lost wages. In California, that's typically about two-thirds of their average weekly wage, up to a state-set maximum. As of 2025, the maximum temporary disability payment is $1,680.29 per week.
Permanent disability. If the injury results in lasting impairment, the employee may receive permanent disability payments. The amount depends on the severity of the impairment and how it affects their ability to work going forward.
Death benefits. If an employee dies from a work-related injury or illness, workers' comp provides benefits to their surviving dependents.
For most small restaurants, cafes, salons, and retail shops in Southern California, the claims that actually come up are medical treatment and short-term temporary disability. Kitchen burns. Slips on wet floors. Back injuries from lifting boxes. These are the everyday situations your policy needs to handle.
Workers' comp does not cover injuries that happen outside of work, intentional self-inflicted injuries, or injuries that occur while an employee is intoxicated or committing a crime.
What It Costs
Workers' compensation premiums are calculated as a rate per $100 of payroll. What you pay depends on three things: the job classification of your employees, your total payroll, and your claims history.
Job classifications matter because different types of work carry different levels of risk. A retail sales associate in a Newport Beach boutique has a much lower risk profile than a line cook at a breakfast spot in Fountain Valley. In California, retail roles typically run $0.40 to $1.00 per $100 of payroll, while restaurant kitchen workers run $1.00 to $5.00 per $100 depending on the specific classification.
To get a rough estimate: multiply your monthly payroll by 12 to get your annual payroll, divide by 100, then multiply by your applicable rate. A restaurant with $20,000 per month in total payroll at a 2.0 rate would estimate roughly $4,800 per year in premium, or $400 per month.
California also applies an experience modification rate, called an e-mod, based on your claims history. If your business has had few or no claims over the past several years, your e-mod falls below 1.0 and you pay less than the standard rate. If you've had multiple claims, it rises above 1.0 and your costs go up. Your claims history follows you from year to year, which is one of the strongest financial arguments for running a safe operation.
One important note on California specifically: rates here run roughly 1.65 times the national average, driven by the state's higher medical costs and more generous benefits. California's Insurance Commissioner also approved an 8.7% advisory rate increase that took effect in September 2025. If you haven't revisited your premium recently, now is a good time to review it.
Where to Get Coverage
You have three options in California.
Private insurance carriers. Most small businesses purchase coverage from a licensed private insurer. A business insurance broker can shop multiple carriers and help you understand what you're getting. If you already carry general liability or a business owner's policy, start with the same broker.
State Compensation Insurance Fund. The State Fund is a public option that competes with private insurers and is required to offer coverage to any California employer who applies. That makes it a reliable fallback if your claims history has made private carriers reluctant to write your policy. You can get a quote at the State Fund's website.
Self-insurance. Only large employers that meet specific financial requirements set by the state are eligible. This is not a practical option for most small businesses.
If you're not sure where to start, call a business insurance broker and ask for a workers' comp quote. Most brokers can have coverage in place within a few days.
What to Do When Someone Gets Hurt
Buying the policy is step one. Knowing how to handle a claim is step two. Most small business owners haven't thought this through until they need it.
Here is what California law requires after a work injury is reported.
Within one business day, give the employee a DWC-1 claim form. This is a legal requirement, not optional. The form is available for download from the California Division of Workers' Compensation.
Within one business day of receiving the completed form back, forward it to your insurance company along with a Report of Occupational Injury or Illness.
Within one business day of receiving the claim form, authorize up to $10,000 in appropriate medical treatment while the claim is being reviewed. You cannot delay care while waiting for the insurer to accept or deny the claim. The employee has the right to begin treatment immediately.
After that, your insurer takes the lead. They investigate the claim, determine what's covered, and manage the payments. Your job is to cooperate, document what happened, and keep communication moving.
If the employee is temporarily unable to perform their full duties, talk to your insurer about modified or light-duty work. If you can offer a role that fits within their medical restrictions, it can shorten the duration of temporary disability payments and keep the employee connected to the job during recovery.
The Penalty for Not Having It
Failing to carry workers' compensation when you're required to is a criminal offense in California.
The penalties under California Labor Code Section 3700.5 include fines up to $100,000 and up to one year in county jail. The state can also issue a stop order requiring you to immediately cease using employee labor until you get covered.
Beyond the legal penalties, if an uninsured employee gets injured, you pay all medical costs and lost wages directly out of pocket, plus you face civil litigation with no insurance coverage behind you. There is no realistic scenario where skipping workers' comp saves money.
How to Keep Your Costs Down
The biggest lever on your premium over time is your claims history. Fewer claims means a lower e-mod, which means lower premiums in subsequent years. Here is how that plays out practically.
Train new employees before putting them in high-risk situations. Most workplace injuries happen in the first 90 days on the job. New employees don't know the workflow yet, don't know where the hazards are, and often feel pressure to keep up without asking for help. Slowing down kitchen or stockroom training pays off in fewer injuries and lower long-term insurance costs. The guide to training hourly employees covers what that looks like in practice.
Document your safety procedures. A written standard for how to operate equipment, lift heavy items, and handle cleaning chemicals does two things: it sets a clear expectation and creates a record that you communicated it. Your employee handbook is a natural place to include safety procedures specific to your operation.
Take near-misses seriously. If something almost went wrong, fix the underlying issue before it becomes a claim. Businesses that track and investigate near-misses consistently have fewer injuries over time than those that don't.
Shop your coverage annually. Rates change, insurers change, and your classification can sometimes be reviewed and corrected. A broker who shops your policy each year can find real savings.
Include workers' comp in your total labor cost calculation. Premium costs are part of what it actually costs to employ someone, alongside payroll taxes, overtime, and sick leave. If your labor cost percentages feel off, make sure you're accounting for all of these. The labor cost percentage guide walks through how to think about total labor cost as a percentage of revenue.
A Note on Hiring and Claims
This isn't directly a workers' comp point, but it's connected. The people you hire affect your claims rate.
Employees who are a good fit for the job, who understood the physical demands before they started, and who were trained properly from day one are less likely to cut corners or rush into situations where an injury is likely. Thorough hiring and onboarding reduces turnover, and it tends to reduce the kind of rushed behavior that leads to accidents.
My Friendly Staff helps small businesses in Orange County screen applicants on the front end. Applicants call in, get screened by an AI voice agent, and come to you ranked by how well they meet your criteria. You spend your interview time on people who actually qualify. Better hiring leads to longer-tenured employees, and employees who know the job tend to work more safely.
The Short Version
If you have employees in California, you need workers' compensation insurance. Getting set up is straightforward. A broker can put a policy in place within a few days, and the State Fund is there as a fallback.
The ongoing work is building habits that keep injuries less likely: clear training, documented safety procedures, and real attention to near-misses. Those habits compound into a lower e-mod over time and directly reduce one of your biggest operating costs.
