Contractor Insurance for California Builders
Every coverage California contractors need — general liability, workers' comp, commercial auto, tools and equipment, builders risk, and CSLB bonds. From a broker who knows construction.
California Business & Professions Code §7125: All licensed contractors must maintain workers' compensation coverage. Operating without proper insurance can result in CSLB license suspension, civil penalties, and personal liability for job-site injuries.

What California Contractors Face
Construction in California means high-risk jobs, strict licensing rules, and exposures most brokers don't understand. These are the real problems we solve every day.
CSLB License at Risk
Without proof of workers comp and general liability on file with the CSLB, your license can be suspended. We handle the paperwork and renewals so your license stays active.
Job Site Injuries Are Expensive
California construction WC class codes (5403, 5645, 5183) run 8-25% of payroll. Combined with frequent injuries on job sites, workers' comp is often the biggest insurance line item — and where we save you the most.
Subcontractor Liability Gaps
If your sub injures someone or damages property, you can be named in the lawsuit. Certificates of insurance from subs are not enough. We structure coverage that closes these gaps.
Tool Theft & Equipment Loss
California job sites are frequent theft targets. A stolen compressor, generator, or set of power tools can stop work for days. Tools and inland marine coverage protect this exposure.
Project-Specific Coverage Requirements
Larger GCs and government contracts require specific limits, additional insured endorsements, and waivers of subrogation. We provide certificates within hours, not days.
The Coverage Stack Every Contractor Needs
California contractors need 5-7 coverages working together. Buying them piecemeal from different carriers creates gaps. We package them properly.
General Liability
Required by CSLB for license renewal. Every commercial GC and most homeowner contracts require proof of GL before work starts. Covers third-party bodily injury and property damage at job sites — including completed operations after the job is done.
Workers' Compensation
Required by California law for any contractor with employees. Sole proprietors often need a 'ghost policy' for CSLB compliance even with zero employees. Construction class codes carry the highest WC rates — accurate classification can save 10-30%. Ex-mod disputes (we challenge incorrect modifiers) can save thousands more.
Commercial Auto
Trucks, vans, work vehicles, and trailers — all need commercial auto, not personal auto. Personal policies exclude business use. Many CA carriers offer combined fleet coverage for 3+ vehicles at significant discounts. Hired and non-owned auto liability protects you when employees use their own vehicles for work runs.
Tools & Equipment (Inland Marine)
Standard property policies don't cover tools off-premises. Inland marine schedules portable equipment (compressors, generators, power tools, lifts) for coverage anywhere — at the shop, on a job site, or in transit. Critical given how often job-site theft happens in California.
Builders Risk
Project-specific coverage during construction. Protects materials at the site, in transit, and stored offsite. Required by most lenders on new builds and major renovations. Coverage ends when the project is complete. Important: standard GL does NOT cover the building you are constructing — only builders risk does.
CSLB License Bond
Every licensed California contractor must maintain a $25,000 contractor's license bond on file with the CSLB. This is not insurance — it's a guarantee to the state and consumers. Bond renewals happen annually. LLC contractors need an additional $100,000 employee/worker bond.
Umbrella / Excess Liability
California is one of the most lawsuit-friendly states for plaintiffs. A serious injury at a job site can quickly exceed your GL limits. Umbrella coverage layers $1-5M on top of your GL, auto, and (sometimes) employer liability for relatively low premium. Many larger commercial contracts require umbrella.
Commercial & Surety Bonds
Beyond the basic CSLB bond, larger projects require additional bonds. Performance bonds guarantee project completion. Bid bonds back your bid on government contracts. Payment bonds protect subs and suppliers. Fidelity bonds protect against employee dishonesty. We write all of them through CA-approved surety markets.
Most contractors need 4-6 of these working together. We package them properly so there are no gaps and no double-coverage waste.
Build My Coverage Package →Why Use a Broker for Contractor Insurance
Buying construction insurance direct from a carrier means one carrier's product. We shop 50+ California carriers — including specialty markets that don't sell to the public — to build the right stack at the right price.
Specialty Construction Markets
Direct-to-consumer carriers (Biberk, Hiscox, NEXT) often decline high-risk construction class codes — roofing, demolition, structural steel. We have appointments with specialty markets and surplus-lines carriers that write what others won't.
CSLB Compliance Handled
We file your workers comp certificate with CSLB, track your license bond renewal, and provide certificates of insurance to your clients within hours. Most contractors lose hours per week on insurance paperwork — we eliminate that.
Ex-Mod & Class Code Disputes
Misclassified workers comp class codes are the #1 reason contractors overpay. We audit your class codes free. We also dispute experience modifier increases that often follow stale claims. Both routinely save 10-30% on WC premium.
Multi-Carrier Bid at Renewal
Every year at renewal we shop your full coverage stack across multiple carriers. Most direct-to-consumer policies auto-renew at whatever the carrier wants. We pit carriers against each other to keep premiums competitive over the long term.
California Contractor Compliance Specifics
The technical details that separate California contractor insurance from generic small-business insurance. We handle all of this.
CSLB License Bond ($25,000)
All licensed CA contractors must maintain a $25,000 surety bond. We write CSLB bonds in 24 hours, with annual renewals tracked automatically. Bond cost typically $200-$600/year depending on credit.
LLC Employee Bond
If you operate as an LLC, the CSLB requires a separate $100,000 LLC employee/worker bond. We handle this on top of the standard license bond.
Workers Comp Certificate Filing
CSLB requires your workers comp certificate of insurance be filed directly with them, not just held by you. We file it automatically when your policy is issued or renewed.
Sole Proprietor Ghost Policies
Sole proprietors with zero employees still often need workers comp for CSLB compliance or general contractor contracts. A 'ghost policy' satisfies these requirements at minimum premium ($600-$1,200/year typically).
Subcontractor COI Tracking
GCs need certificates of insurance from every subcontractor. We can set up COI tracking so you always have current certificates on file — critical for CSLB audits and lawsuit defense.
Additional Insured Endorsements
Most commercial contracts require you to name the property owner or GC as an additional insured. We handle these endorsements at no extra charge, usually within hours of the request.
Contractor Workers Comp Class Codes
Workers' comp premium = payroll × class code rate × experience modifier. Wrong class code = massive overpayment. These are the most common construction codes we audit and place.
| Code | Trade | Notes |
|---|---|---|
| 5403 | Carpentry — N.O.C. | Most common general construction code |
| 5645 | Carpentry — Dwellings (1-3 family) | Lower rate than commercial carpentry |
| 5538 | Sheet Metal Work | HVAC, ductwork, metal roofing |
| 5183 | Plumbing | Includes water heater installation |
| 5190 | Electrical Wiring | Inside electrical, panel work |
| 5547 | Roofing | Higher rates, falls and burns |
| 5474 | Painting | Indoor and exterior painting |
| 5022 | Masonry | Brick, block, stone work |
| 5183 | HVAC Installation | Air conditioning, heating |
| 5403 | General Building Contractor | GC oversight without trade work |
Many contractors are overpaying because of misclassified codes. We audit your class codes free — typical savings 10-30% on workers comp premium.

Contractor Insurance FAQ
Every licensed California contractor must carry: (1) a $25,000 CSLB license bond, and (2) workers' compensation insurance if you have any employees. Most contracts require general liability insurance with $1M-$2M limits. Beyond these requirements, commercial auto (if you own work vehicles) and tools/inland marine coverage are highly recommended. LLCs need an additional $100,000 LLC employee bond. Project-specific requirements vary by contract.
Costs vary by trade, revenue, payroll, and claims history. Typical ranges: General liability $800-$4,000/year for small operations. Workers' comp 8-25% of payroll for construction class codes. CSLB license bond $200-$600/year. Commercial auto $1,500-$3,000 per vehicle. Tools/inland marine $400-$1,500/year depending on insured value. Specialty trades (roofing, demolition, structural) run higher. We provide same-day quotes from 50+ carriers.
General liability protects you from third-party injury or property damage claims — when a customer, passerby, or property gets hurt or damaged. Workers' comp protects your employees if they're injured on the job and pays for their medical bills and lost wages. They cover completely different exposures, and California law requires both for contractors with employees. They're often confused but never interchangeable.
California law doesn't require workers comp for sole proprietors with zero employees. However, the CSLB still requires proof of workers comp coverage OR a signed exemption affidavit. Many contracts (especially with GCs and government agencies) require workers comp regardless of employee status. The solution is a 'ghost policy' — a minimum-premium workers comp policy that satisfies both CSLB and contract requirements at minimum cost.
Yes. Multiple claims or a high experience modifier (ex-mod) raise premiums but don't disqualify coverage. We work with claim-tolerant carriers and surplus-lines markets that write non-standard construction risks. We also frequently challenge incorrect ex-mod calculations from previous carriers — successful ex-mod disputes can drop your rate immediately. Honest disclosure up front is key; carriers find out anyway through industry databases.
What California Contractors Say About Our Service
"Our CSLB renewal was at risk because of an ex-mod issue from a stale claim. They got us re-quoted with a carrier that wrote our class code at almost half the cost — and filed the certificate with CSLB the same day."
"We switched our whole package — GL, workers' comp, commercial auto, and tools coverage — to one broker. Saved over $4,200 across the policies and finally have someone who answers when we call."
"Found out from them we were missing builders risk coverage on a $400K project. They got us covered before we broke ground and we had no idea our old broker had let it lapse. Saved us from a real disaster."
