California is the largest small-business market in the country, and wildfire, high medical and legal costs, and high labour costs all show up in its premiums. Even so, Insureon’s small business customers in California pay a median of $42 a month for general liability, a little under the national $45. Below are the 2026 numbers by coverage, trade and headcount, what drives them, and the one rule every California employer needs to know before the first hire. For the 50-state picture, see average business insurance cost by state.
Average business insurance cost in California by coverage
The table shows what a California business of two to five people in a middling risk class pays for the three policies most small businesses carry. Professional liability, also sold as errors and omissions, responds when a client says your work cost them money. A business owner’s policy adds property cover on your own equipment and premises.
| Coverage | Typical monthly | Typical annual | What it covers |
|---|---|---|---|
| General liability ($1M per occurrence) | $28–$56/mo | $336–$672/yr | Third-party injury and property damage; the policy a client or landlord asks for by name. |
| Professional liability (E&O) | $70–$140/mo | $840–$1,680/yr | Claims that your advice or work cost a client money, legal defence included. |
| Business owner’s policy (BOP) | $47–$93/mo | $564–$1,116/yr | General liability plus commercial property, usually with business-interruption cover. |
| Hiscox advertised starting price | from $22.50/mo | from $270/yr | E&O from $22.50, general liability from about $29, a BOP from about $42. |

See these costs for your own business size, revenue and state
Most California businesses start with general liability because somebody else demands it: a Los Angeles landlord, a San Diego property manager who wants a certificate before your crew cleans, a Bay Area client whose vendor agreement will not clear procurement without one. A business owner’s policy earns its higher price once you own equipment, stock or a lease, because it adds property and business-interruption cover for less than two separate policies. Our guide to general liability vs professional liability vs BOP explains which to buy first.
California business insurance cost by trade
Your trade moves the premium more than your address. A consultant who never leaves the laptop is a cheaper risk than a roofer, and insurers price that gap with a risk class. Here are twelve common trades in California, two to five people, $1M/$2M limits.
| Trade | General liability | Business owner’s policy |
|---|---|---|
| Consultant | $20–$40/mo | $34–$69/mo |
| IT or software developer | $23–$46/mo | $26–$52/mo |
| Accountant or bookkeeper | $19–$37/mo | $34–$67/mo |
| Photographer or videographer | $18–$36/mo | $26–$53/mo |
| Real estate agent | $21–$41/mo | $33–$65/mo |
| Online store (e-commerce) | $26–$52/mo | $53–$107/mo |
| Personal trainer or fitness | $18–$36/mo | $33–$66/mo |
| Cleaning or janitorial | $30–$60/mo | $43–$85/mo |
| Landscaping or lawn care | $32–$63/mo | $53–$106/mo |
| Auto repair shop | $34–$67/mo | $84–$168/mo |
| Restaurant or café | $88–$175/mo | $141–$282/mo |
| General contractor | $101–$202/mo | $47–$93/mo |
Estimates from Insureon’s published medians for each business type for California, for two to five people at the standard $1M/$2M limits. Not quotes.
We cover five of these trades in their own California guides: cleaning businesses in California, personal trainers in California, photographers in California, real estate agents in California and marketing consultants in California.
Cost by business size
Headcount matters too: every hire is another pair of hands that can drop a client’s server or leave a wet floor unsigned, and Insureon says more staff and more revenue generally mean higher premiums. It publishes no prices by headcount, so the table below only shows where in the California range a business of each size is likely to sit.
| Business size | General liability |
|---|---|
| Just me | $28–$42/mo |
| 2 to 5 people | $28–$56/mo |
| 6 or more people | $42–$56/mo |
Estimates from Insureon’s published medians for California, not quotes. No source publishes prices by headcount, so we show the lower half of the range for a one-person business under $100k in revenue, the whole range for two to five people, and the upper half for six or more. Larger businesses often pay more than this, especially for workers’ comp.
Business insurance cost in Los Angeles, San Diego and other California cities
No source publishes prices by city, so our estimate is statewide: a business in Los Angeles and one in a small inland town get the same estimate of $28–$56 a month for the same trade, size and limits. What changes city to city is the local business tax certificate you register for and, in a BOP's property section, how exposed the address is to wildfire.
| City | General liability | Local business tax certificate |
|---|---|---|
| Los Angeles | $28–$56/mo | LA Office of Finance, business tax registration certificate |
| San Diego | $28–$56/mo | City of San Diego, business tax certificate |
| San Jose | $28–$56/mo | City of San Jose, business tax certificate |
| San Francisco | $28–$56/mo | SF Office of the Treasurer & Tax Collector, business registration |
| Fresno | $28–$56/mo | City of Fresno, business tax certificate |
Statewide estimate from Insureon’s published medians for California, not a quote; no source publishes prices by city. Local registration shown is the city business tax certificate, not insurance, and requirements vary by trade.
Businesses in and around Los Angeles and other wildland-urban interface areas see the wildfire exposure show up in the property side of a BOP, so the $47–$93 BOP range tends to run higher there than in a denser, lower-fire-risk city like San Francisco, even though general liability pricing does not move by city.
Why California costs what it does
Insureon’s California customers pay a median of $42 a month for general liability, a little under the national $45, but $63 a month for workers’ comp, against $54 nationally. Four things push California premiums up, most of all for property and payroll-based cover.
- Wildfire exposure. Any policy that covers property pays for the state’s fire history, and a BOP feels it most. Businesses in the wildland-urban interface, from the Sierra foothills to the Santa Monica Mountains, price highest.
- High medical and legal costs. A liability claim in California pays for some of the highest medical bills and legal fees in the country, and both are baked into every trade’s liability rates.
- A large litigation environment. California sees more lawsuits against businesses than any other state, and carriers price the frequency of claims as well as their size.
- High labour costs. Premiums scale with payroll, and California payroll runs higher than almost anywhere else, which shows up most in workers’ comp.
What California requires
The California Department of Insurance (CDI), led by an elected Insurance Commissioner, regulates insurers, approves their rates and forms, and licenses agents.
Workers’ compensation is required for any employer with even one employee, under Labor Code section 3700. There is no headcount threshold and no industry carve-out: the day you put someone on payroll, you need a policy in place.
Contractors are licensed by the Contractors State License Board (CSLB), which requires a contractor’s license bond and proof of workers’ compensation coverage, or an exemption, before it issues or renews a licence. Licensing rules change, so check CSLB or CDI for current specifics before you rely on this page.
How to lower your premium in California
These are the levers that most often bring a California premium down.
- Get the classification right. A bookkeeper rated as a general consultant pays for a risk they do not carry. Describe the work precisely when you quote.
- Quote real revenue. Premiums scale with revenue, and quoting projections instead of actual figures means overpaying until renewal.
- Buy the limits the contract asks for, not more. $1M/$2M satisfies nearly every California lease and vendor agreement.
- Take a higher property deductible. The fire exposure sits in the property side of a BOP, and a higher property deductible is the most direct way to bring that part down.
- Bundle into a BOP. If you need property cover at all, a BOP is almost always cheaper than general liability plus a standalone property policy.
- Stay claims-free and pay annually. Carriers price a clean loss history lower at renewal, and most charge less for one annual payment than for twelve monthly ones.
Where these numbers come from
The figures at the top of this page and in the main cost table come from the same data as our cost estimator, so the two always agree. The starting point is the median premium that Insureon, an online insurance agency, publishes for its small business customers (see its California page). We adjust it for the state using Insureon’s state medians, and show the band that Insureon’s own price distribution says most businesses fall in. Every figure is an estimate, not a quote. The full method and source list is on the estimator page.
Frequently asked questions
How much is business insurance in California per month?
A California business of two to five people typically pays about $28–$56 a month for general liability, $70–$140 for professional liability and $47–$93 for a business owner’s policy.
Is business insurance more expensive in California than the national average?
Not for general liability. Insureon’s small business customers in California pay a median of $42 a month for general liability, against $45 nationally, so a two to five person business typically pays about $28–$56 a month here against $30–$60 nationally. Workers’ comp runs higher, at a median of $63 a month against $54 nationally, and wildfire exposure can push the property side of a business owner’s policy up.
Do I need workers’ compensation in California?
Yes, from the first employee. California Labor Code section 3700 requires workers’ compensation for any employer with even one employee, with no headcount threshold and no industry carve-out. Contractors also have to show the Contractors State License Board proof of coverage or an exemption to hold a licence.
How much does $1 million liability insurance cost in California?
A $1 million per occurrence, $2 million aggregate general liability policy costs a typical California business of two to five people about $28–$56 a month, or $336–$672 a year. That is the standard limit a landlord or commercial contract asks for, and a one-person business under $100k in revenue pays closer to $28–$42 a month.
What is the cheapest business insurance in California?
General liability on its own is the cheapest policy for most California businesses, and desk-based businesses such as a one-person consultancy are among the cheapest to insure. Insureon’s figures put general liability for a one-person consultancy in California at about $20–$30 a month.
How much is business insurance in Los Angeles?
The same as anywhere else in California: about $28–$56 a month for general liability for a two to five person business; no source publishes prices by city, so our estimate is statewide. Wildfire exposure in and around Los Angeles shows up in the property side of a business owner’s policy rather than in general liability itself, so a Los Angeles business tends to land toward the higher end of the $47–$93 BOP range.
