Coverage Stack for California Contractors
What insurance do California contractors actually need? Here’s the standard stack — adjusted for California’s regulatory environment and risk profile.
General Liability
Minimum $1,000,000 per occurrence required. Covers bodily injury, property damage, and completed operations claims. Required by most project owners, GCs, and permit offices in California.
Workers Compensation
Workers compensation is required in California for employers with 1 or more employees (sole proprietors may exempt themselves). Trade Safe shops competitive rates across dozens of A-rated carriers to find the right fit for your trade, payroll, and claims history.
Commercial Auto
Personal auto policies exclude business use. Any vehicle driven to jobsites, hauling tools or materials, or lettered with your company name needs a commercial auto policy.
Tools & Equipment
Covers theft, damage, and loss of tools and equipment on the jobsite or in transit. Especially important for specialty trades with high-value equipment in California.
Builders Risk
Covers structures under construction for fire, storm, vandalism, and theft of materials. Required on most financed projects. Critical in California given its specific weather exposures.
Surety Bonds
$15,000 contractor license bond (mandatory) required for California licensure. License & permit bonds, performance bonds, and payment bonds available. Trade Safe arranges bonding alongside your insurance package.
Wildfire exposure in California affects builders risk and property coverage availability. Earthquake proximity adds complexity for larger projects. Environmental regulations can trigger pollution liability requirements.
What California Contractors Need to Know About Insurance
Three things that catch California contractors off-guard — and how to stay ahead of them.
The $1,000,000 GL Minimum Is Just the Floor
California requires $1,000,000 per occurrence in general liability coverage — one of the highest mandatory minimums in the country. But many project owners in California require $2M or more, especially for commercial work. Make sure your policy limits match what your contracts actually require, not just the state minimum.
License Renewal: Biennial
California requires biennial license renewal. Missing your renewal date doesn’t just create a lapse in your license — it can also void your insurance policy if your coverage was conditioned on maintaining licensure. Set reminders 90 days before your renewal date and confirm your insurance agent has updated certificates ready when your new license term starts.
CSLB Enforcement Is Aggressive
California’s CSLB actively investigates unlicensed contracting — fines up to $15,000 and potential criminal prosecution. They run sting operations and accept anonymous tips. Every subcontractor you hire must also be properly licensed and insured. If an unlicensed sub is found on your jobsite, you can be held responsible. Keep certificates of insurance for every sub on file.

Frequently Asked Questions — California Contractor Insurance
How much general liability insurance do I need as a contractor in California?
California requires a minimum of $1,000,000 per occurrence in general liability coverage for most contractor license classifications. However, the state minimum is often just the floor — project owners, general contractors, and lenders frequently require higher limits. Commercial projects commonly require $1M or $2M per occurrence regardless of the state minimum. Trade Safe reviews your contracts and recommends appropriate limits so you’re covered for what you actually bid.
When is workers compensation required for California contractors?
California requires workers compensation for employers with 1 or more employees (sole proprietors may exempt themselves). Even if you’re under the threshold, carrying WC can help you win contracts — many GCs and project owners require it regardless of the legal minimum. Trade Safe shops WC rates across multiple carriers to find the best fit for your trade, payroll, and loss history.
How do I get a contractor license in California?
Contractor licensing in California is handled by California Contractors State License Board. License types include: Class A (General Engineering), Class B (General Building), Class C (44 Specialty classifications). You’ll need to meet the state’s insurance minimums ($1,000,000 per occurrence GL, $15,000 contractor license bond (mandatory)), pass any required exams, and submit your application with proof of insurance and bonding. Trade Safe can provide the certificates of insurance and bond arrangements you need to complete your application.
What surety bond is required for a California contractor license?
California requires a $15,000 contractor license bond (mandatory) as part of the contractor licensing process. A surety bond is not insurance — it’s a financial guarantee to the state and your clients that you’ll fulfill your contractual obligations. Trade Safe can arrange surety bond coverage alongside your GL and other insurance lines, simplifying the paperwork for your license application.
Does my homeowner’s auto policy cover my work truck in California?
No — personal auto policies typically exclude business use, including driving to jobsites, hauling tools and materials, and any vehicle used in connection with your trade. If you’re involved in an accident while using a personal vehicle for work, your personal auto policy may deny the claim. Any vehicle used for business purposes needs a commercial auto policy. Trade Safe handles commercial auto alongside your GL so all your coverage is coordinated.
Does my CSLB license require a specific insurance certificate format?
CSLB requires your insurance certificates to list the Contractors State License Board as an additional insured and to meet the minimum $1M general liability requirement. Your bond must also be filed directly with CSLB. If your insurance lapses, CSLB is notified and your license can be suspended within 30 days. Trade Safe monitors your policy and alerts you before any lapse that would affect your license.
