Average General Liability Insurance Cost in California (2026 Report)

Business size is the most influential factor in general liability pricing. Insurers use it as a straightforward measure of risk: the more employees you have, the higher your premiums, because a larger workforce raises the likelihood of third-party claims like bodily injury, false advertising and subpar work complaints.

General liability insurance costs in California for 1 to 4 employee businesses are two times larger than for a sole proprietor at 107% higher. That gap widens sharply as headcount grows, reaching well over 4,000% once you reach 20 to 49 employees compared to an owner-only operation.

California's Proposition 103 requires insurers to obtain Department of Insurance approval before implementing rate changes for commercial lines, including business owners' policies and other liability coverage, through a prior approval system.
