California Insurance Is Different. Work With a Broker Who Knows It.
California contractor insurance is one of the most complex markets in the country. Higher litigation costs, strict labor laws, the WCIRB experience modifier system, CSLB-specific bond requirements, and surplus-lines-only trades all change how coverage is priced and placed. A general agent who writes a few CA policies a year cannot navigate this market the way a specialist can.
CA-Licensed Independent Broker
Altamira holds California License No. 6017420 and places coverage with multiple admitted and surplus-lines carriers writing California contractor business.
All Trades, All Sizes
From sole-proprietor handymen to multi-state general contractors with $50M+ in receipts. We write standard, hard-to-place, and wrap-up programs.
Responsive Service
Direct access to a licensed account manager. Certificates of insurance issued promptly with additional insured and waiver of subrogation endorsements as required by California GCs and property owners.
X-Mod & Class-Code Review
We review every California workers comp renewal for X-mod accuracy and class-code splits — small errors that quietly cost contractors thousands per year.
Core Coverages for California Contractors
General Liability
Covers third-party bodily injury and property damage from your work. Required by virtually every CA general contractor, property owner, and public agency. Typical limits: $1M per occurrence / $2M aggregate.
Workers' Compensation
Required by California law for any contractor with employees, including part-time. Premium is X-mod-multiplied — small claims have outsized long-term cost.
CSLB Contractor License Bond
$25,000 bond required to maintain an active CSLB license. $12,500 Bond of Qualifying Individual required when an RMO or RME qualifies the license.
Builders Risk
Covers structures under construction against fire, theft, vandalism, and weather. Critical for new builds, additions, and major remodels. We place CA wildfire-zone projects.
Commercial Auto
Required for vehicles owned or used by the business. Service vans, trucks, equipment trailers. Hired and non-owned auto endorsements available.
Commercial Umbrella
Adds $1M–$10M+ above your GL and auto limits. Required by many CA general contractors and public works projects with $5M+ liability requirements.
Inland Marine
Covers tools, equipment, and materials in transit or on the job site. Theft from job sites and vehicles is the #1 inland marine claim for California contractors.
Pollution Liability
Critical for trades with environmental exposure — HVAC, roofing, abatement, demolition, excavation. Standard GL excludes most pollution claims.
Estimated Cost of Contractor Insurance in California
The ranges below are estimates only — actual quotes vary widely based on the cost factors listed further down this page. They reflect typical $1M / $2M general liability premiums for California contractors with annual receipts of $100K–$2M and a clean three-year loss history. Smaller contractors at the low end of the revenue range can sometimes price below these figures; larger contractors and those with prior claims, residential remodel exposure, condominium/habitational work, or wildfire-zone exposure typically price above.
Important: these are estimates, not quotes. Actual price depends on many factors including deductible level, three-year loss history, type of work performed (new construction vs. service-and-repair, residential vs. commercial), subcontracted work, project size, payroll, territory within California, and carrier appetite for your specific class code. Two contractors with the same CSLB classification can pay materially different premiums.

Workers compensation is priced separately and not reflected in the table above. CA workers comp varies dramatically by class code and X-mod, and is typically the largest single insurance line item for contractors with employees. Builders risk, commercial auto, inland marine, and umbrella are also priced separately. Numbers above assume $1M occurrence / $2M aggregate GL with a standard $0–$2,500 deductible. Higher deductibles and self-insured retentions can reduce premium meaningfully.
What Drives Your California Contractor Premium?
Five factors do most of the work in determining what you pay for general liability and workers compensation in California:
Trade & CSLB class code
A C-39 roofer and a C-33 painter price very differently. The CSLB classification dictates which carriers will quote you and at what rate.
Annual revenue & payroll
GL premium is rated on receipts; workers comp is rated on payroll by class code. Higher numbers mean higher base premium — but also better carrier selection.
Coverage limits
Most CA contracts now require $1M / $2M GL minimums; many commercial and public works projects require $5M+. Higher limits cost more but unlock larger jobs.
Claims history (3 years)
Loss runs from your prior carriers drive both pricing and which markets will quote. A single open claim can cut your carrier options in half.
Operations & territory
New construction vs. service-and-repair, residential vs. commercial, single-county vs. statewide — each shifts carrier appetite. Wildfire-zone work adds builders risk surcharges.
Deductible & SIR
A higher deductible (or self-insured retention on excess layers) reduces premium but increases out-of-pocket exposure on a claim. Often a useful lever for established contractors with low loss history.
What California Contractors Are Required to Carry
California contractor insurance has both legal mandates (CSLB and Cal/DIR) and contractual mandates (GCs, property owners, public agencies). Here's what every active CA license needs to stay compliant and bid jobs:
$25,000 CSLB License Bond
Required by the Contractors State License Board for every active license. License is suspended if the bond lapses. We issue the bond and the $12,500 Bond of Qualifying Individual when applicable.
Workers' Compensation
Required by California law for any contractor with one or more employees, including part-time. C-39 roofing licenses must carry workers comp regardless of employee count. Penalties run $1,500 per employee plus stop-work orders.
General Liability ($1M/$2M typical)
Not required by the CSLB itself, but required in practice by virtually every general contractor, property owner, public agency, and commercial client before they let you on the job. No GL = no work.
