General liability is your first line of defense against third-party claims — bodily injury, property damage, personal injury, and advertising injury. For California contractors, it's not optional. We structure CGL programs that meet GC requirements, satisfy CSLB standards, and actually protect your business when something goes wrong.
A Commercial General Liability (CGL) policy, standardized under ISO form CG 00 01, provides three core coverages for businesses: Coverage A (bodily injury and property damage liability), Coverage B (personal and advertising injury liability), and Coverage C (medical payments). For contractors, Coverage A is where the vast majority of claims arise.
Bodily injury and property damage claims trigger when your work causes harm to someone else or damages their property. A pedestrian tripped by debris from your job site. A homeowner's floor damaged by a plumbing leak your crew caused. A subcontractor injured because of unsafe conditions you created. These are the scenarios your CGL policy responds to.
Most contractor CGL policies are written on an "occurrence" basis, meaning the policy in effect when the incident occurred responds — regardless of when the claim is filed. This is critical for construction work because defects may not be discovered for years. California's statute of limitations for construction defects is four years for patent (visible) defects under CCP Section 337.1 and ten years for latent (hidden) defects under CCP Section 337.15.
Completed operations coverage is the portion of your CGL policy that responds to claims arising from work you've already finished. For contractors, this is arguably the most important coverage — the majority of construction defect claims come after project completion. Without adequate completed operations limits, you're exposed to the very claims most likely to be filed against you.
We see contractors every week who don't realize their policy has a completed operations aggregate that's already been eroded by prior claims. Understanding your remaining limits mid-term is essential, and it's something we monitor for every client.
Every general contractor in California requires their subcontractors to carry general liability insurance — typically $1,000,000 per occurrence and $2,000,000 general aggregate at minimum. Many commercial GCs require $5M or even $10M in combined limits, which means you'll need an umbrella or excess liability policy to meet their requirements.
When a GC hires you as a subcontractor, they'll almost always require that they be added to your policy as an additional insured. This is done through endorsements — the most common being CG 20 10 (ongoing operations) and CG 20 37 (completed operations). These endorsements extend your liability coverage to protect the GC for claims arising from your work.
The specific endorsement forms matter. Some carriers issue blanket additional insured endorsements that automatically cover any party you're contractually required to add. Others require individual endorsements for each project. We structure policies with blanket additional insured language so you're never scrambling to get endorsements issued mid-project.
Most commercial contracts also require a waiver of subrogation — meaning your insurance carrier waives its right to pursue the GC for claims it pays on your behalf. This must be endorsed onto your policy before the loss occurs. We include blanket waivers of subrogation on all contractor policies to ensure you're always contract-compliant.
We provide same-day certificate issuance for our clients. When a GC needs proof of coverage at 7am to let you on the job site, we don't make you wait until the office opens at 9. Our certificate process is built for the reality of how construction actually works — fast, accurate, and with the exact endorsements the GC requires.
General liability premiums for contractors are typically calculated based on your annual revenue or payroll, your specific trade classification, your claims history, and the coverage limits you need. Rates vary dramatically by trade:
Low-hazard trades like electrical or plumbing may see rates of $3-$8 per $1,000 of revenue. Moderate-hazard trades like carpentry or concrete typically fall in the $8-$15 range. High-hazard classifications — roofing, tree trimming, demolition — can run $15-$40 or more per $1,000 of revenue, depending on claims history and carrier appetite.
Your claims history is the single biggest factor you can control. A clean loss history not only qualifies you for preferred carriers with better rates, it also unlocks schedule credits of 15-25% that aren't available to contractors with frequent claims. Conversely, two or three liability claims in a three-year window can make you uninsurable in the standard market, forcing you into surplus lines carriers that charge 2-3x the standard rate.
We don't just find you the cheapest quote. We structure your entire liability program — CGL, umbrella/excess, and any specialty coverage — as an integrated package. This means coordinating limits, ensuring no gaps between underlying and excess layers, negotiating favorable audit provisions, and positioning your account with carriers that specialize in your trade.
For contractors who need higher limits, we build layered programs using multiple carriers. A typical structure might be $1M/$2M primary CGL with a $5M umbrella or $1M/$2M primary with a $4M/$4M excess — giving you the $5M total limit that most commercial GCs require at a fraction of what a single $5M primary policy would cost.
Premiums depend on your trade, revenue, and claims history. Low-hazard trades (electrical, plumbing) typically pay $3-$8 per $1,000 of annual revenue. Moderate trades (carpentry, concrete) run $8-$15. High-hazard classifications (roofing, tree trimming) can be $15-$40+. A typical small contractor with $500K in revenue might pay $2,000-$6,000 annually for a $1M/$2M policy.
The industry standard minimum is $1,000,000 per occurrence and $2,000,000 general aggregate. However, most commercial general contractors require subcontractors to carry $2M per occurrence or higher, often with $5M-$10M in total limits through an umbrella policy. Your required limits depend on the contracts you want to pursue.
An occurrence policy covers incidents that happen during the policy period, regardless of when the claim is filed. A claims-made policy covers claims filed during the policy period. For contractors, occurrence policies are strongly preferred because construction defects may not surface for years. California allows up to 10 years for latent defect claims.
Completed operations is the portion of your CGL policy that covers claims from work you've already finished. For contractors, this is critical — most construction defect lawsuits come after project completion. California's statute of repose extends to 10 years for latent defects, meaning claims can emerge long after you've left the job site.
If you work as a subcontractor, virtually every GC will require you to add them as an additional insured on your CGL policy. This extends your coverage to protect them for claims arising from your work. We recommend blanket additional insured endorsements so you're automatically compliant with every contract without needing individual endorsements per project.
CGL policies exclude your own employees' injuries (covered by workers' comp), your own property damage, professional errors (need E&O), auto-related claims (need commercial auto), pollution (need environmental liability), and intentional acts. They also exclude damage to your own work — the 'your work' exclusion — though subcontractor work may be covered depending on the policy form.
