General Liability Insurance for Contractors: Costs, Coverage & Best Providers
Without general liability insurance, a single incident can result in a lawsuit that costs more than an entire year's revenue.
Contractors face unique liability risks on every job site — a subcontractor injury, accidental property damage, a client claiming faulty workmanship. Without general liability insurance, a single incident can result in a lawsuit that costs more than an entire year's revenue. This guide covers everything contractors need to know about GL coverage in 2026.
Key fact: Most general contractors, building owners, and project managers require proof of at least $1M in general liability coverage before allowing work to begin on site.
What Does General Liability Insurance Cover for Contractors?
- Third-party bodily injury: A client or visitor is injured at a job site you're working on
- Third-party property damage: You accidentally damage a client's home, building, or belongings while working
- Completed operations: A client claims your finished work caused injury or property damage after the job is done
- Personal and advertising injury: Libel, slander, or copyright infringement claims
- Legal defense costs: Attorney fees, court costs, and settlements up to your policy limit
What it does NOT cover:
- Your own tools or equipment (commercial property/inland marine)
- Employee injuries (workers' compensation)
- Professional errors in design or engineering (professional liability)
- Vehicle accidents (commercial auto)
- Intentional damage or fraud

What Factors Affect a Contractor's GL Premium?
- Trade type and risk level: Roofers and excavators pay more than painters and landscapers
- Annual revenue / payroll: Higher revenue = more exposure = higher premium
- Years in business: Newer contractors may pay more without a loss history
- Claims history: Prior claims raise rates significantly
- Coverage limits: $2M aggregate costs more than $1M
- Location: States with high litigation rates (CA, FL, NY) have higher premiums
- Number of subcontractors used: Using uninsured subs increases your liability
Do Contractors Need Additional Coverage Beyond GL?
General liability is the foundation, but most contractors also need:
- Workers' Compensation: Required by law in most states if you have employees. Covers medical costs and lost wages from on-the-job injuries.
- Commercial Auto: Covers vehicles used for business purposes. Personal auto policies exclude business use.
- Tools & Equipment (Inland Marine): Covers theft or damage to your tools, typically $500–$1,500/year for $10,000–$50,000 in coverage.
- Builder's Risk: Covers structures under construction. Often required by project owners.
- Commercial Umbrella: Adds $1M–$5M above your GL limits for large projects or high-risk work.

It's not universally required by law, but most states require it to obtain a contractor's license. Nearly all commercial clients and general contractors require proof of GL coverage before work begins.
