Carpenter insurance cost usually runs $80 to $100 a month for general liability. Workers’ comp often adds another $250 to $300 a month once you have a crew. Those are averages, so your own quote may come in higher or lower. If you frame houses, hang cabinets, or build decks, these bills hit before your first invoice clears. Many general contractors won’t let you on a job site without proof of coverage. Some states won’t issue or renew your license without it either. This guide breaks down what carpenters typically pay, what drives the price, and how to avoid overpaying.
What Carpenter Insurance Cost Looks Like in 2026
Insureon’s 2026 data for carpenters shows general liability at about $85 a month, or $1,020 a year. General liability pays when you damage a client’s property or someone gets hurt because of your work. For example, it may cover a ladder that falls through a homeowner’s window. Thimble reports a median of about $98 a month for carpenter liability coverage. The Hartford quotes standalone general liability nearer $68 a month.
Workers’ compensation is the big swing factor. Insureon puts the carpenter average at $282 a month, or $3,388 a year. Workers’ comp pays medical bills and lost wages when an employee gets hurt on the job. Carpentry is a high-injury trade, so rates run higher than for office businesses. However, a solo carpenter with no employees may pay little or nothing for it.
Other common policies add smaller amounts. Insureon lists commercial auto at about $160 a month for carpenters. Tools and equipment coverage runs about $14 a month. That policy covers saws, nail guns, and other gear if they’re stolen from your truck or job site.
Exact Figures That Drive Your Price
Your carpenter insurance cost depends mostly on where you work, your payroll, and the kind of carpentry you do. Workers’ comp is priced per $100 of payroll. Each type of work gets a “class code,” and each code has its own rate. Rates can range from about $2.50 to over $40 per $100 of payroll, depending on the code and the state.
Here is the basic math. Take your payroll, divide by 100, and multiply by your class rate. Then multiply by your “experience mod.” That’s a score based on your past injury claims. A clean record can push it below 1.0, which lowers your bill. As a result, one bad claim can raise your premium for about three years.
| Item | Typical figure |
|---|---|
| General liability (national average) | $85/month ($1,020/year) |
| Workers’ comp (national average) | $282/month ($3,388/year) |
| Commercial auto | $160/month |
| Tools and equipment | $14/month |
| California: general liability / workers’ comp | $153 / $460 per month |
| Texas: general liability / workers’ comp | $125 / $152 per month |
| California contractor license bond (CSLB) | $25,000 |
State rules matter a lot. California generally requires workers’ comp once you have even one employee. Florida generally requires construction businesses to carry it with one or more employees, and that can include corporate officers. Texas is the rare state where most private employers can choose not to carry it. In most cases, sole proprietors are excluded from workers’ comp by default. You can often opt in, though, if a general contractor demands it. Check your state’s workers’ comp division for the exact rule.
Licensing can add costs too. For example, California’s Contractors State License Board requires a $25,000 contractor bond for licensed contractors. A bond is not insurance for you. Instead, it protects your clients if you fail to finish the job or break licensing law. Typically, you pay a yearly premium of a small percentage of the bond amount, based on your credit.
How to Lower Your Carpenter Insurance Cost
First, ask about a business owner’s policy, or BOP. A BOP bundles general liability and property coverage into one policy. It typically costs less than buying the two separately. However, BOPs don’t include workers’ comp or commercial auto, so you’ll still need those if they apply to you.
Second, make sure your workers’ comp class code fits the work you actually do. A finish carpenter installing trim shouldn’t be rated like a framer working on a third-story roof line. Wrong codes are a common reason carpenters overpay. Also, track subcontractor certificates of insurance, or COIs. A COI is a one-page proof of coverage. If a sub you hire has no coverage, your carrier may charge you for their payroll at your annual audit.
Third, compare at least three quotes every year. Check the limits, not just the price. Many general contractors ask for $1 million per claim and $2 million total for general liability. They often want to be named as an “additional insured” too. That means your policy also protects them if your work causes a claim. Confirm the details with a licensed agent before you sign.

Frequently Asked Questions
How much is carpenter insurance cost per year for a one-person business?
A solo carpenter often pays about $1,000 to $1,200 a year for general liability alone. If you skip workers’ comp because you have no employees, your total stays low. However, adding commercial auto or tools coverage can bring the total closer to $3,000.
Do I need workers’ comp if I’m a self-employed carpenter?
In most states, sole proprietors with no employees aren’t required to carry it. However, many general contractors still ask subs for proof of workers’ comp before they’ll hire them. Some states also treat construction differently, so confirm the rule with your state’s workers’ comp agency.
Why is carpenter insurance cost so much higher in California?
California has higher medical and legal costs, along with strict workers’ comp rules. As a result, Insureon’s figures show California carpenters paying about $460 a month for workers’ comp, versus $152 in Texas. Typically, general liability costs more there too.
