Short answer: California law requires very little business insurance, but what it does require is serious. If you have even one employee, including part-time, you must carry workers' compensation (Labor Code §3700), and operating without it is a misdemeanor with a fine of at least $10,000 (§3700.5). Any vehicle your business owns needs at least $30,000/$60,000/$15,000 in liability, and some licensed trades, such as LLC contractors, must carry liability insurance or bonds. Everything else, including general liability, property, professional liability, cyber and umbrella, isn't required by state statute, but leases, client contracts, lenders and venues usually require some of it, and most businesses need it to survive a lawsuit or a fire. Start with what's required, then add what your contracts demand, then cover the risks that could close your doors.
This guide is for California small business owners, from a one-person consultancy to a restaurant or contracting company with a crew. It separates legal requirements from contract requirements and from good practice, and it links to our deeper guides by industry. It's general information, not legal advice. Your licensing board, contracts and policies control the details.
Three layers of "required"
When people ask whether insurance is required, they usually mean one of three things:
- Required by law. A statute or license rule says you must carry it. Failing to carry it can bring fines, stop orders or license trouble.
- Required by contract. Your landlord, a client, a general contractor, a lender, a franchisor or an event venue says you must carry it, often with set limits and their name added as an additional insured. You won't be fined by the state, but you can lose the lease or the job.
- Recommended. No one makes you buy it, but one claim could cost more than your business can absorb.
Keeping these apart helps you spend money where it matters.
Layer 1: What California law requires
| Coverage | Who needs it | Source |
|---|---|---|
| Workers' compensation | Any employer with one or more employees, full- or part-time | Labor Code §3700 |
| Penalty for going without | Misdemeanor punishable by up to one year in county jail, a fine of up to double the premium that would have been due (at least $10,000), or both | Labor Code §3700.5 |
| Auto liability | Every business-owned vehicle; at least 30/60/15 for policies issued or renewed since Jan. 1, 2025 | Vehicle Code §16056 |
| For-hire property carriers | $300,000 or $750,000 depending on vehicle weight | Vehicle Code §34631.5 |
| Contractors | A $25,000 contractor's bond, a workers' comp certificate or valid exemption, and, for LLC licensees, liability insurance of at least $1,000,000 | CSLB |
Workers' comp: the requirement owners miss most
The rule applies from the first employee. It doesn't matter if the person works only a few hours or is a relative on payroll. The state can also issue a stop order that shuts down operations, with a penalty of $1,500 per employee, and larger penalties apply if an employee is hurt while you're uninsured. Read California uninsured employer penalties, what happens if workers' comp lapses and our California workers' comp small business guide.
Calling someone an independent contractor doesn't settle it. California applies its own tests to decide who is an employee, and a worker you pay on a 1099 can still be your employee for workers' comp. See do I need workers' comp for 1099 contractors? and who is exempt from workers' comp in California.
Even with no employees, a household worker you hire at home can count as your employee for workers' comp. See household employee workers' comp. Other states have different rules; see workers' comp requirements by state.
Commercial auto
If the business owns the vehicle, it needs at least the state minimum, and most commercial policies carry far more because contracts often ask for $1,000,000. If you or your employees drive personal cars on business errands, a personal policy may not respond the way you expect; ask about hired and non-owned auto coverage. See California commercial auto insurance minimums and what is hired and non-owned auto insurance?
License-specific rules
Some trades and professions carry their own insurance or bond rules through their licensing body. Contractors are the best-known example. See California contractor insurance and bond requirements and the contractor workers' comp 2028 guide. Cannabis businesses face license bond and insurance rules too; see California cannabis license bond and insurance requirements. If you hold any state license, check your board's rules each renewal.
Layer 2: What contracts usually require
These coverages aren't required by state statute for most businesses, but you'll be asked for proof of them often.
- General liability (GL). Covers third-party bodily injury and property damage from your premises and operations, such as a customer slipping in your shop. Commercial leases, clients and venues commonly require it, often with the landlord or client named as an additional insured. See is general liability insurance required in California?
- Property insurance. Leases often require tenants to insure their improvements and contents, and lenders require it on financed buildings and equipment.
- Professional liability (E&O). Clients that rely on your advice or design, such as tech clients or property managers, often require it in the contract. See is professional liability insurance required in California?
- Umbrella or excess liability. Large clients and general contractors often require limits above a single policy's limits.
- Cyber liability. More client and vendor contracts now ask for it.
Before you sign a lease or contract, read the insurance section and send it to your broker. Requirements such as "primary and non-contributory," "waiver of subrogation" or specific limits may require endorsements.
Layer 3: What's recommended for most businesses
Think about what could close your doors, then cover that first.
| Risk | Coverage to consider | Learn more |
|---|---|---|
| A customer is hurt or their property is damaged | General liability | General liability insurance |
| Fire, theft or water damage to your space, equipment or stock | Commercial property | Commercial property insurance |
| You have to close after a covered loss and still owe rent and payroll | Business interruption | What is business interruption insurance? |
| A client says your advice or work cost them money | Professional liability | Professional liability insurance |
| A data breach or ransomware | Cyber liability | Cyber liability insurance |
| An employee sues for discrimination, harassment or wrongful termination | Employment practices liability (EPLI) | EPLI |
| A lawsuit bigger than your policy limits | Commercial umbrella | Commercial umbrella insurance |
| Employee theft or fraud | Commercial crime | Commercial crime insurance |
| Earthquake damage to your building or stock | Commercial earthquake | Commercial earthquake insurance |
Many small businesses start with a business owner's policy (BOP), which packages general liability and property, and often business interruption, at a lower combined cost than buying them separately. See what a business owner's policy covers and BOP vs. general liability.
If you work from home, don't assume your homeowners policy covers the business. Many homeowners policies limit business property and exclude business liability. See California home-based business insurance requirements.
Forming an LLC or corporation can limit some personal liability, but it doesn't replace insurance, and the business itself can still be sued. See does an LLC need business insurance in California?
Step by step: building your business insurance plan
Step 1: List your people
Count everyone who works for you, including part-time staff, family members on payroll and anyone you pay on a 1099. If any of them are employees, workers' comp comes first.
Step 2: List your vehicles and how they're used
Note who owns each vehicle and what it's used for. Business-owned vehicles need commercial auto. Employees driving personal cars for work raises a hired and non-owned auto question.
Step 3: Check your license rules
Look up your licensing board's insurance and bond requirements and note renewal dates.
Step 4: Collect your contracts
Pull your lease, major client contracts, loan documents and any franchise agreement. Highlight every insurance requirement, including limits, additional insured wording and waivers.
Step 5: Map your biggest risks
Ask what one event could cost you the most: an injury on site, a fire, a professional mistake, a data breach, an employee lawsuit. Rank them.
Step 6: Get quotes that meet every requirement
Give your broker the list from Steps 1 to 5. Ask for options that meet every legal and contract requirement, then options for your top recommended coverages.
Step 7: Compare more than price
Compare limits, deductibles, exclusions, whether defense costs reduce the limit, and whether professional or cyber policies are claims-made. See claims-made vs. occurrence insurance.
Step 8: Get certificates and keep them current
Request certificates of insurance for landlords and clients, and calendar every expiration date. A lapse in workers' comp or a required policy can cost you a contract, or worse.
Step 9: Review every year, and whenever something changes
Hiring, buying a vehicle, signing a new lease, adding a service or moving all change your insurance needs. Tell your broker before the change, not after.

Frequently asked questions
What business insurance is required by law in California?
Workers' compensation if you have any employees (Labor Code §3700), liability insurance on business-owned vehicles (Vehicle Code §16056), and any insurance or bonds your license requires, such as the contractor's bond and LLC liability insurance for contractors.
Is general liability insurance required in California?
Not by state law for most businesses. But leases, clients, venues and some licenses require it, so many businesses need it in practice.
Do I need workers' comp if I have only one part-time employee?
Yes. California requires workers' comp from the first employee, full- or part-time. Going without is a misdemeanor with a fine of at least $10,000 (Labor Code §3700.5).
Do I need business insurance if I work from home?
Often yes. Many homeowners policies limit business property and exclude business liability. A home-business endorsement, a BOP or a separate liability policy can fill the gap.
Does forming an LLC mean I don't need insurance?
No. An LLC can limit some personal liability, but the business itself can still be sued and still has to meet workers' comp and other legal requirements.
What is a business owner's policy?
A package that combines general liability and commercial property, often with business interruption, usually for small and mid-sized businesses. It's often less expensive than buying the same coverages separately.
