What Carpentry Contractors Need to Know About Insurance in California
Framing vs. Finish — Different Risk Profiles
C-5 framing contractors carry significantly higher risk than C-6 finish carpenters. Multi-story structural framing, scaffolding, fall exposure, and nail gun injuries drive up both workers' comp and GL rates. Finish carpenters working interiors have a more moderate risk profile. Make sure your broker rates your actual operations — not a generic "carpentry" category.
SB 800 Construction Defect Law Applies to You
California's SB 800 Right to Repair Act establishes standards for residential construction and a specific notice-and-repair process before a homeowner can sue. Carpentry subcontractors can be pulled into defect claims years after project completion. Your GL policy's completed operations coverage must be structured to respond to California's construction defect framework.
GC Subcontract Insurance Requirements Are Tightening
California general contractors increasingly require carpentry subs to carry $1M–$2M per-occurrence GL, name the GC and owner as additional insureds, provide waiver of subrogation, and maintain umbrella coverage. Review the insurance exhibit of every subcontract before signing — and verify your policy can meet each requirement before you start work.
Disclose All Operations — C-5 and C-6 Both
If you hold both a C-5 and a C-6 license and perform both framing and finish work, both operations must be disclosed to your carrier. Policies that only rate one scope can void claims arising from the undisclosed operation. A broker experienced with California carpentry contractors will structure your policy to cover your full operational footprint.
Coverage for California Carpentry Contractors
General Liability
Covers third-party bodily injury and property damage from carpentry operations. Completed operations coverage responds to construction defect claims under California's SB 800 framework after project completion.
Workers' Compensation
Legally required for any California employee. Framing crews face fall hazards, nail gun injuries, and heavy material handling. Covers medical treatment, lost wages, and rehabilitation for injured workers.
Commercial Auto
Covers your work trucks and vehicles used to transport lumber, tools, and workers to job sites. Personal auto policies exclude commercial use — any vehicle used for business needs commercial auto coverage.
Umbrella / Excess Liability
Provides additional limits above your primary GL. Most GC subcontracts on commercial and multi-family projects require $2M–$5M in total liability. Umbrella is cost-effective protection for framing and finish contractors alike.
Tools & Equipment (Inland Marine)
Covers your saws, nail guns, scaffolding, and other tools against theft, damage, and loss at job sites or in transit. Essential for carpentry contractors with significant tool investments. GL does not protect your own equipment.

Frequently Asked Questions — Carpentry Contractor Insurance in California
