What General Contractors Need to Know About Insurance in California
GCs Carry the Broadest Liability Exposure
As the prime contractor, a California Class B GC is responsible for the entire project — including the work of every sub you hire. A defective sub installation that results in a claim often flows back to the GC. Your GL policy must have adequate limits, proper endorsements, and completed operations coverage that extends through the California statute of limitations for construction defects.
Subcontractor Compliance Is Your Responsibility
If a subcontractor you hire doesn't carry valid workers' comp, California law can hold you responsible for their employees' injuries. Collect and verify COIs from every sub before work begins. A construction-savvy broker can help you implement a subcontractor compliance program — this is standard practice for well-run GC operations.
Builder's Risk Is Project-Specific — Don't Assume It's Covered
Builder's risk insures the structure under construction against fire, theft, vandalism, and weather. Many GCs assume the owner carries it — but contracts vary. Verify in writing who is responsible for builder's risk before breaking ground. Gaps in builder's risk coverage on a project can result in catastrophic uninsured losses.
Public Works Has Additional Requirements
California public works projects (schools, government buildings, infrastructure) require DIR registration, prevailing wage compliance, payment and performance bonds, and specific insurance requirements including higher GL limits and sometimes project-specific aggregate endorsements. A broker experienced with California public works understands these compliance layers.
Coverage for California General Contractors
General Liability
The cornerstone of a GC's insurance program. Covers third-party bodily injury and property damage. For California GCs, $1M/$2M is a common minimum — commercial projects and public works often require higher. Completed operations coverage is essential for California's construction defect exposure.
Workers' Compensation
Legally required for any California employee. GCs must also manage subcontractor workers' comp compliance. Covers medical treatment, lost wages, and rehabilitation — and protects GCs from upstream liability when subs fail to carry proper coverage.
Commercial Auto
Covers your project trucks, superintendent vehicles, and other company vehicles used in business operations. GCs often have larger fleets than specialty trades — commercial auto should cover all company-owned and regularly used vehicles.
Umbrella / Excess Liability
Nearly all commercial GC contracts require an umbrella. $2M–$5M is typical; some public agency and large commercial projects require $10M or more. Umbrella sits above your GL and commercial auto — essential for any GC doing significant project volume.
Tools & Equipment (Inland Marine)
Covers your tools, equipment, and temporary structures at job sites. Even GCs who primarily manage subs maintain significant equipment investments — inland marine fills the gap that GL leaves for your own property.

Frequently Asked Questions — General Contractor Insurance in California
GL ($1M/$2M is common minimum), workers' comp (legally required for employees), commercial auto, umbrella ($2M–$5M for commercial work), builder's risk on projects under construction, and the $25K CSLB bond (a separate surety product). Public works contracts have additional requirements.
CSLB Class B allows GCs to manage multi-trade construction projects. It is separate from Class A (General Engineering) and the 40+ C specialty licenses. Requires $25K bond and qualifying experience or exam.
Yes. If a sub doesn't carry valid workers' comp, California law can hold you responsible for their employees' injuries. Require current COIs from every sub, verify them with the carrier, and include hold harmless language in every subcontract.
Builder's risk covers the structure under construction against fire, theft, vandalism, and weather. Either the GC or the owner carries it — the contract specifies who. Confirm builder's risk is in place before breaking ground on any project.
More than specialty trades due to broader scope. GL for a GC typically starts at $2,000–$8,000/yr depending on revenue and project type. Workers' comp is calculated on total payroll. Umbrella adds significantly but is required on most commercial work. Request a quote for accurate California pricing.
