Contractor Insurance: What You Need and How Much It Costs (2026)

One lawsuit from a job site injury, property damage claim, or contract dispute can bankrupt an uninsured contractor. Courts regularly award judgments of $500,000–$2,000,000+ against contractors.

Beyond liability, most clients — especially commercial GCs — require proof of insurance before they'll hire you. No certificate of insurance (COI) = no job.

This guide covers every type of insurance contractors need, typical costs, and how to buy it.

What it covers: Third-party bodily injury and property damage you cause during your work. If a client trips over your extension cord and breaks their arm, GL covers the claim.

Typical limits:
- $1M per occurrence / $2M aggregate: industry standard for most commercial work
- $500K / $1M: acceptable for small residential work
- $2M / $4M+: required by some large GCs and public projects

What it does NOT cover: Your own injuries, your employees' injuries (that's workers' comp), your tools (that's inland marine), completed work that fails (that's a professional liability or warranty issue).

Cost: $500–$2,500/year for a small sole proprietor. $2,000–$10,000+ for a company with employees. High-risk trades (roofing, demolition) pay more.

Pro tip: Get additional insured endorsements that your GCs can request. This is standard — any carrier should do this for free or minimal cost.

What it covers: Medical expenses and lost wages for employees injured on the job. In most states, it's illegal to have employees without workers' comp.

Who needs it: Any contractor with W-2 employees. Some states require sole proprietors to carry it too. Many GCs require subs to have it even if they're solo.

Cost: Varies enormously by trade classification (roofing averages $20–$30 per $100 payroll; painting is $4–$6; office/clerical is under $1). For a roofing crew with $300K payroll, expect $60,000–$90,000/year in workers' comp.

Ghost policy (or stop-gap): If you're a sole proprietor with no employees but GCs require you to have workers' comp, a "ghost policy" covers just you as a named insured. Cost: $1,000–$1,500/year. Allows you to provide a COI.

Audit: Workers' comp policies are audited annually based on actual payroll. Don't misclassify workers to lower premiums — this is fraud.

What it covers: Vehicles used for business purposes — your work truck, van, company vehicles.

Why you need it: Personal auto policies explicitly exclude commercial use. If you're driving to a job site in your work truck and get in an accident, your personal insurer will deny the claim.

Cost: $1,200–$3,500/year per vehicle, depending on vehicle type, driver history, and location.

Hired & Non-Owned Auto: If employees use their personal vehicles for business, add this coverage to your general liability policy. Relatively cheap ($200–$500/year) and important.

Fleet policies: Once you have 3+ vehicles, fleet policies usually save 10–20% vs. individual policies.

What it covers: The project under construction — structure, materials on site, materials in transit.

When you need it: When you're the prime contractor on a project. (GCs on commercial jobs usually provide this; you may need to add it as a named insured.)

What it covers: Fire, theft, vandalism, wind, hail. Usually does NOT cover floods, earthquakes, or employee theft without endorsements.

Cost: 1–4% of the total project value per year. On a $500,000 project: expect $5,000–$20,000 for the coverage period.

Term: Policy runs for the project duration (typically 6–18 months). Extends if the project is delayed.

What it covers: Your tools and equipment — both on the job site and in transit.

Why it matters: Tools get stolen. Constantly. A pickup truck broken into on a job site can easily result in $10,000–$50,000 in tool losses. Your commercial auto policy does NOT cover contents.

Cost: $500–$2,000/year depending on the value of tools and equipment you own.

Scheduled vs. blanket coverage: Scheduled covers specific listed items; blanket covers all tools up to a limit. Blanket is easier; scheduled is better for high-value equipment.

Pro tip: Keep an inventory of your tools with serial numbers and photos. Claims require proof of ownership.

Option 1: Independent insurance agent — Best for most contractors. An independent agent shops multiple carriers and knows construction. They can bundle policies and find specialized coverage.

Option 2: Online platforms — Next Insurance, Thimble, and Hiscox offer quick online quotes for small contractors. Good for starting out; may lack specialized coverage as you grow.

Option 3: Association programs — AGC, NAHB, NECA, and other trade associations often have group insurance programs at below-market rates.

What to bring when shopping:
- Revenue projections (or actuals)
- Payroll by employee class
- Type of work (residential vs commercial; by trade)
- Loss history (3–5 years of claims, if any)
- List of vehicles

Always compare: Get at least 3 quotes. Rates vary 30–50% between carriers for the same coverage.
