Contractor insurance cost is one of the first real numbers you hit when you start or grow a trade business. It also comes up when a general contractor or homeowner asks for your certificate of insurance before you can start a job. Many owners guess low, then get surprised by a workers’ comp quote or a license requirement they didn’t know about.
The good news is the main costs are predictable once you know what drives them. This guide covers typical premiums, the state rules that force certain coverage, and how to keep your bill reasonable without leaving gaps. The goal is simple. You should know what you need and what it usually costs before you sign anything.
What Drives Contractor Insurance Cost
Your trade matters more than almost anything else. Carriers sort businesses by classification codes, and each code carries its own risk level. For example, a painter or handyman usually pays far less than a roofer. A roofer works at height, so falls and big injury claims are more likely. As a result, the same $500,000 in revenue can cost very different amounts by trade.
General liability is the core policy most contractors buy first. It pays when your work injures someone else or damages their property. For example, it can cover a client who trips over your tools, or a ceiling you damage during a remodel. Insureon reports that contractors pay an average of about $83 per month, or $990 a year, for general liability. Other industry estimates for small contractors typically run from about $58 to $188 per month.
Workers’ comp is usually the biggest line item once you hire. It pays medical bills and lost wages when an employee gets hurt on the job. Premiums are figured per $100 of payroll, so more payroll means a bigger bill. Your experience mod also matters. That is a score that compares your claims history to similar businesses. A mod under 1.0 lowers your rate, and a mod over 1.0 raises it.
State Rules and Exact Figures That Affect Contractor Insurance Cost
Some of your contractor insurance cost is not optional. States set rules for licensing, bonds, and workers’ comp. In most cases, these rules apply even if your clients never ask for proof. However, the rules differ a lot from state to state, so check yours before you budget.
California is a big example. Under SB 216, all contractors with a CSLB license generally must carry workers’ comp starting January 1, 2026, even with no employees. Roofers (C-39) and a few other trades were required earlier, starting in 2023. California also requires a $25,000 contractor’s bond for licensed contractors. A bond is not insurance for you. Instead, it protects your customers if you fail to follow licensing law.
Florida has its own rules. Construction businesses there generally need workers’ comp with even one employee. That is much stricter than the four-employee threshold for most non-construction businesses. Texas is the opposite. Most private employers there, including contractors, may choose not to carry workers’ comp. However, opting out removes key legal protections if a worker sues.
| Item | Typical Figure | Where It Applies |
|---|---|---|
| General liability, average | About $83/month ($990/year) | National average for contractors (Insureon) |
| Contractor license bond | $25,000 | California (CSLB) |
| Workers’ comp for all licensed contractors | Required starting Jan. 1, 2026 | California (SB 216) |
| Workers’ comp employee threshold, construction | 1 employee | Florida |
| Workers’ comp for private employers | Generally optional | Texas |
Four states run monopolistic workers’ comp systems: Ohio, Washington, North Dakota, and Wyoming. In a monopolistic state, you must buy workers’ comp from the state fund, not a private carrier. As a result, you can’t shop that policy around. You can still shop your general liability, auto, and other coverage.
How to Lower Your Contractor Insurance Cost Without Cutting Corners
Start with what your state and your contracts require. Pull your licensing board’s insurance and bond rules first. Then read the insurance section of your typical client contract. Many general contractors require $1 million per occurrence and $2 million aggregate on general liability. They often also ask to be listed as an additional insured. That means your policy also protects them for claims tied to your work.
Next, look at a business owner’s policy, or BOP. A BOP bundles general liability and commercial property into one policy. For many small contractors, a BOP typically costs less than buying the two separately. However, BOPs usually exclude workers’ comp and commercial auto. You will still need those on separate policies if they apply to you.

Finally, get at least three quotes from different sources. Make sure each quote uses the same limits, deductible, and trade codes. Otherwise, you are comparing apples to oranges. Ask about paying annually instead of monthly, since some carriers charge installment fees. Also, report payroll and revenue accurately. Low estimates can lead to a large bill at your year-end premium audit. Confirm details with a licensed agent and your state before you buy.
Your contractor insurance cost will also move over time. A clean claims record can lower your experience mod. Safety training and written safety programs may also earn credits with some carriers. On the other hand, adding trucks or higher-risk work will raise rates. Review your coverage each year at renewal.
Frequently Asked Questions
How much is contractor insurance per month for a small business?
For general liability alone, many small contractors pay roughly $58 to $188 per month. Insureon reports an average of about $83 per month. However, workers’ comp and commercial auto can raise your total contractor insurance cost well above that.
Do I need workers’ comp if I have no employees?
It depends on your state. For example, California generally requires workers’ comp for all licensed contractors starting in 2026, even solo operators. In most other states, solo owners can typically skip it unless a client contract requires it. Confirm the rule with your state’s workers’ comp agency.
Why is my roofing insurance so much higher than a painter’s?
Roofing has more frequent and more severe injuries, mostly from falls. As a result, carriers price roofing classification codes much higher. In most cases, roofers see the biggest difference on workers’ comp, where rates are tied to payroll and risk.
