Is general liability insurance just a checkbox on your contractor license application—or a shield against catastrophic loss?
What happens when a subcontractor causes a $250,000 water leak in a high-end residential build, and your current policy maxes out at $100,000?
This comprehensive guide explores general liability insurance through the lens of 2,600+ real California contractors. It includes coverage essentials, risk insights, limit analysis, and prevention strategies shaped by claims data, litigation trends, and real-world exposure.
Covered topics include:
Core components of general liability coverage
California-specific liability exposures
Data-driven coverage limit benchmarks
The most common claims and how they arise
Exclusions, gaps, and how to close them
Risk and claims management strategies using modern tools
General liability insurance protects contractors from third-party claims for bodily injury, property damage, and reputational harm tied to business operations or completed work.
Bodily Injury Liability
Protects against injuries caused by job site operations, tools, or conditions.
Examples: Slip-and-fall claims, falling object injuries, equipment mishaps, or exposure to construction chemicals.
Property Damage Liability
Covers damage to other people’s property during construction activities.
Examples: Water damage from plumbing installs, fire from faulty wiring, or landscaping damage during staging.
Personal and Advertising Injury
Covers non-physical claims such as libel, slander, or misuse of intellectual property.
Examples: Defamation accusations or copyright issues in advertising.
Products and Completed Operations
Applies after the project is finished, covering long-tail risks like structural failures or material defects.
Minimum CSLB coverage (often 1M/2M) falls short for many projects. Risk level, property values, and contractual demands influence ideal limits.
Small projects (<$100K): 1M/2M
Mid-sized projects ($100K–$1M): 2M/4M
Large projects ($1M–$10M): 5M/5M
Major projects (>$10M): Base plus umbrella (10M–25M+)
Umbrella policies offer high-limit protection without proportionally high costs and are often required for commercial, industrial, or public works contracts.
California’s legal and environmental context increases both the likelihood and cost of claims.
