What insurance does a California contractor need?

California contractors typically need general liability insurance, workers' compensation insurance (required by law for any employee), commercial auto insurance for work vehicles, and a contractor license bond. The CSLB requires a $25,000 contractor license bond for most license classifications. Many commercial projects and GC contracts also require an umbrella policy.

Is workers' compensation required for California contractors?

Yes. California law requires all employers — including contractors — to carry workers' compensation insurance for any employee, including part-time workers and subcontractors who do not carry their own coverage. Failure to carry workers' comp in California can result in stop-work orders, fines, and personal liability for employee injuries.

What is the CSLB contractor bond requirement?

The California Contractors State License Board (CSLB) requires all licensed contractors to carry a $25,000 contractor license bond. This bond protects consumers if a contractor fails to complete work, causes property damage, or violates license laws. The bond is renewed with your CSLB license and is separate from your general liability insurance.

How much does contractor insurance cost in California?

California contractor insurance costs vary by trade, revenue, payroll, and coverage limits. General liability for a small California contractor typically starts around $1,200–$3,500/year. California rates are higher than most states due to dense population, high property values, and strict labor regulations. Workers' comp rates also vary significantly by trade classification. Submit a quote request for accurate California-specific pricing.

What trades require a California contractor license?

Any construction work in California valued at $500 or more (labor and materials combined) requires a CSLB contractor's license. This includes general contractors (Class B), electrical (C-10), plumbing (C-36), HVAC (C-20), roofing (C-39), painting (C-33), concrete (C-8), carpentry (C-5/C-6), flooring (C-15), drywall (C-9), excavation (C-12), and acoustical (C-2), among others.

Q: Do I need insurance to get a CSLB license?

Yes. To obtain and maintain a CSLB contractor's license, you must have an active $25,000 contractor license bond on file with the CSLB. While general liability insurance is not technically required by the CSLB itself, it is required by virtually all general contractors, public agencies, and commercial clients as a condition of being awarded work.

Why It Matters

Sound Familiar?

The wrong broker doesn't just cost you money — it costs you jobs.

My Broker Is a Generalist

They don't know construction, don't understand your trade, and miss coverage gaps that matter on a California job site.

My COI Got Rejected

Prime contractors have specific additional insured endorsement and exclusion requirements. A broker who doesn't know the space won't get them right.

Nobody Picks Up the Phone

When you need a certificate or have a coverage question, you can't afford to wait days for a callback.

COIs Take Days — Sometimes Weeks

You can't get paid or start work without a COI in hand. Slow issuance kills your cash flow and risks losing the job entirely.

I Bought the Wrong Coverage

The wrong policy means claims get denied when it matters most. If your broker didn't know your business, you may not be covered the way you think.

My Account Manager Keeps Changing

Constant turnover means re-explaining your business every renewal and falling through the cracks at the worst possible time.

My Broker Got Acquired

When independent agencies sell to nationals, service suffers immediately and your account becomes a number in a queue.

That's why we only match California contractors with brokers who specialize in construction and stay independent. Request a free quote →

Coverage Types

Insurance Every California Contractor Needs

California has some of the strictest construction regulations in the country. From mandatory workers' comp to CSLB bond requirements, we ensure your coverage is in full compliance — and actually protects your business.

General Liability Insurance

Covers third-party bodily injury and property damage during your construction operations. Required by virtually every GC, property manager, and public agency in California before you step on a jobsite.

Bodily Injury Property Damage Completed Ops Personal Injury

Workers' Compensation

California law mandates workers' comp for any employer with at least one employee. Covers medical costs, lost wages, and rehabilitation. Non-compliance triggers stop-work orders and personal liability for the business owner.

Legally Required in CA Medical Bills Lost Wages Rehab Costs

Commercial Auto Insurance

Covers your trucks, vans, and service vehicles used for business — California personal auto policies explicitly exclude business use. Protects against liability and physical damage on the road and at jobsites.

Work Trucks & Vans Liability Collision Hired & Non-Owned

Umbrella / Excess Liability

Extends your liability limits beyond your primary GL or auto policy. Required on most California public works projects, school district contracts, and major commercial GC subcontracts — often $2M–$5M minimum.

Public Works Req'd Higher Limits Broad Coverage

CSLB Contractor License Bond

The CSLB requires a $25,000 contractor license bond for all licensed contractors. This is a separate transaction from your insurance — a surety bond, not an insurance policy. We can connect you with a bond specialist alongside your insurance coverage.

$25K Required Separate from Insurance All Classifications

Tools & Equipment (Inland Marine)

Covers your tools, equipment, and materials in transit, on the jobsite, or in storage. General liability does not cover your own property — a single theft or equipment loss can sideline your operation without this coverage.

Theft Transit Damage Jobsite Loss Equipment Floater

Contractor E&O (Professional Liability)

Covers financial-loss claims that GL excludes — faulty workmanship, wrong specifications, or installation errors that cost a client money without bodily injury or property damage. Increasingly required on design-build and commercial contracts.

Faulty Workmanship Design Errors Financial Loss

Pollution Liability

Covers cleanup costs and third-party claims from pollution conditions your work causes or disturbs — fuel spills, silica dust, disturbed asbestos or lead, stormwater runoff. Standard GL policies exclude pollution.

Cleanup Costs Silica & Dust Runoff Claims

COI Issuance — 24 Hours: Need a certificate of insurance for a GC, project owner, or lender? Standard COIs — including additional insured endorsements — are issued within 24 hours of your request once coverage is bound.

FAQ

California Contractor Insurance FAQ

Common questions from California-licensed contractors about insurance requirements, CSLB bonds, and coverage costs.

California contractors typically need general liability insurance, workers' compensation (legally required for any employee), commercial auto for work vehicles, and a $25,000 CSLB contractor license bond. Many commercial and public works projects also require an umbrella policy of $2M or more.

Yes — California Labor Code requires all employers to carry workers' compensation insurance for every employee, including part-time and seasonal workers. Failure to carry workers' comp is a criminal misdemeanor in California and can result in stop-work orders, fines of up to $100,000, and personal liability for employee injuries.

The CSLB requires all licensed California contractors to maintain a $25,000 contractor license bond. This surety bond protects consumers if the contractor fails to complete work or violates license law. The bond must be on file with the CSLB at all times — a lapse will suspend your contractor's license.

California contractor insurance costs more than most states due to high labor costs, dense population, and regulatory requirements. General liability for a small contractor typically starts around $1,200–$3,500/year. Workers' comp rates vary significantly by trade classification (e.g., roofing is higher risk than painting). Submit a quote for accurate pricing.

You need the $25,000 contractor license bond on file with the CSLB to get licensed. General liability insurance is not technically required by the CSLB itself, but it is required by essentially every GC, property owner, and public agency before you will be awarded work. Most contractors carry both.

Any construction project in California valued at $500 or more in combined labor and materials requires a CSLB license. This covers all trades including Class B General Building Contractors, and all C specialty licenses (C-10 electrical, C-36 plumbing, C-20 HVAC, C-39 roofing, C-33 painting, and dozens more).
