Do I Need Business Insurance in California? What the Law Requires

By Angel Jahani, Jahani Insurance Agency · November 2, 2026 · 5 min read

If you are starting or running a small business in California, one question comes up fast: what insurance do I actually have to carry, and what is just a good idea? Here is a plain-language overview.

The one coverage the law is clear about: workers’ compensation

According to the California Department of Industrial Relations, California law requires employers to have workers’ compensation insurance even if they have just one employee, and benefits cover part-time workers too. The California Department of Insurance adds that the requirement applies to full-time, part-time, temporary and seasonal workers, and to employers organized as corporations, LLCs, partnerships and sole proprietorships.

Failing to carry it is taken seriously. The state describes it as a criminal offense, and consequences can include stop-work orders and fines. The state can also ask for proof of coverage, and employers have 10 days to respond.

Auto insurance if your business uses vehicles

Any vehicle driven in California must meet the state’s minimum liability limits. Since January 1, 2025, those minimums are $30,000 for injury to one person, $60,000 for injury to all people in one accident, and $15,000 for property damage. Those are minimums for any driver. A vehicle used for the business may need more, depending on the work you do and who you work for, so ask about commercial auto coverage if employees or company vehicles are involved.

Coverages that are often not required by law, but are often required by someone else

Many policies are not mandated by the state for every business, yet they come up all the time because a landlord, a client or a general contractor asks for them:

• General liability. Helps cover claims that your business caused injury or property damage to someone else. Clients and landlords commonly ask for proof of it.
• Commercial property. Covers business property such as equipment and inventory against events like fire or theft. Commercial leases often require it.
• Professional liability (errors and omissions). For businesses that give advice or perform professional services, where a client could claim a mistake cost them money.
• Business owner’s policy (BOP). A package that bundles several coverages, often general liability and property, into one policy.

Some industries and licenses carry their own insurance or bonding rules. If you hold a professional or trade license, check what your licensing board asks for.

Questions to ask before you buy

1. Do I have any employees, including part-time or seasonal help?
2. Do my clients, landlord or contracts require specific coverage or limits?
3. Do employees or I drive for the business?
4. What would a single serious claim cost me if I had no coverage for it?
5. What does the policy exclude? Read the exclusions, not just the coverage list.

Why talk to an agent

The right mix depends on what your business does, how many people work in it and what your contracts say. A licensed agent can review those details with you and explain the options in plain words before you decide.
