A ladder slips and shatters a client’s window. A truck full of tools disappears from a job site overnight. Any one of these can cost tens of thousands of dollars, and for a small contracting business, one uncovered loss can end the company. Contractor insurance is the set of policies covering injuries, property damage, vehicle accidents, and stolen tools from construction work.
Quick answer
Contractor insurance is a bundle of business policies built for construction work. General liability is the core policy, and most contractors also need workers’ compensation, commercial auto, tools and equipment cover, and professional liability if they design or advise. A small crew typically pays $6,000 to $20,000 a year for the full package, depending on trade, payroll, and coverage limits.
What contractor insurance covers
Contractor insurance is not one policy but a stack, and each one covers a different risk:
- Damage and injuries you cause to others. General liability pays when your work injures a client or bystander, or damages someone else’s property, including damage found later.
- Legal defense. It also pays to defend a lawsuit, even a groundless one.
- Injuries to your own workers. Workers’ compensation pays medical bills and part of lost wages for a hurt employee.
- Your vehicles. Commercial auto covers trucks and vans used for work, which a personal auto policy usually excludes.
- Your tools and equipment. Tools and equipment cover follows your gear to job sites and in transit.
- Mistakes in your professional work. Professional liability covers claims that faulty design, advice, or supervision caused a loss.
The 5 types of contractor insurance
1. General liability insurance
General liability is the foundation policy for almost every contractor. The U.S. Small Business Administration lists it as a core coverage for any business, protecting against financial loss from bodily injury, property damage, medical expenses, libel, slander, defending lawsuits, and settlements or judgments.
The most common limits are $1 million per occurrence and $2 million in total, and many clients require at least these before they let you on site. Typical cost runs $500 to $3,500 a year: a solo handyman may pay $400 to $900, a residential general contractor more often pays $1,500 to $5,000, and a roofer $3,000 to $12,000 or more.
2. Workers’ compensation insurance
Workers’ compensation pays medical care and part of lost wages when an employee is injured or becomes ill because of the job. Federal rules require businesses with employees to carry it, and state rules add their own requirements.
Premiums follow a formula: annual payroll divided by 100, times a class rate for the work, times an experience modifier from your claims history. Construction trades typically pay $2,000 to $5,000 per employee per year. General carpentry carries a class rate near $6.50 per $100 of payroll, while general construction runs near $8.00 per $100. Four states, Ohio, North Dakota, Washington, and Wyoming, use a state fund only. Texas is the only state letting most private employers opt out, though that leaves the business exposed to injury lawsuits.
3. Commercial auto insurance
Any vehicle used for business needs commercial auto coverage. A personal auto policy typically excludes claims from business use, so an accident on the way to a job site may not be covered at all. Commercial auto covers liability for injuries and damage you cause, and damage to your own truck.
A typical work truck costs $1,800 to $3,600 a year, or about $150 to $300 a month. A light pickup with a clean record often runs $1,400 to $3,000 a year, a cargo van $1,800 to $3,500.
4. Tools and equipment insurance
Tools and equipment cover, known as inland marine insurance, protects your gear while it moves between job sites, sits on a site overnight, or waits in storage. A standard property policy usually only covers property at your business address, so tools stolen from a truck or a job site are often uninsured without this cover.
Small contractors typically pay $350 to $1,200 a year for $50,000 to $150,000 of scheduled equipment, about 1 to 3 percent of the insured value. Keep the equipment list updated: an item never added to the schedule may not be covered.
5. Professional liability insurance
Professional liability, also called errors and omissions insurance, covers claims that a mistake in your work caused a financial loss. The Small Business Administration describes it as protection against malpractice, errors, and negligence for service businesses. It matters most for design-build firms and contractors who offer design or consulting.
General liability does not cover this kind of claim. A small contractor typically pays $1,000 to $5,000 a year for professional liability, while larger design-build firms can pay $5,000 to $20,000 or more.
Who needs contractor insurance
General contractors, subcontractors, remodelers, roofers, electricians, plumbers, HVAC technicians, and handymen face the same basic risks. Solo operators need it too: working alone removes the workers’ compensation bill, not the risk of a client injury claim or a stolen trailer.
Three forces decide what you must carry. Your state licensing board may require specific coverage before it issues or renews a license. Clients and general contractors commonly demand a certificate of insurance before work starts. Lenders and project owners often set minimum limits in the contract. Check your state insurance department before you buy, because requirements vary widely by state and trade.
How much does contractor insurance cost
There is no single price: the premium follows the risk. The table shows typical annual ranges for a small contracting business in 2026.
| Policy | Typical annual cost |
|---|---|
| General liability | $500 to $3,500 |
| Workers’ compensation | $2,000 to $5,000 per employee |
| Commercial auto | $1,800 to $3,600 per vehicle |
| Tools and equipment | $350 to $1,200 |
| Professional liability | $1,000 to $5,000 |
Five factors move the price most: trade, payroll and revenue, limits, claims history, and location. Roofing and demolition cost far more to insure than painting or finish carpentry.
A business owner’s policy can cut the bill: the Small Business Administration describes it as a package combining the typical coverage options, usually general liability plus commercial property, though it does not replace workers’ compensation or commercial auto. To compare quotes fairly, ask every carrier for the same limits and deductibles, and get at least three quotes: premiums for the same risk can differ sharply between carriers.
Worked example: a small remodeling contractor
Example: the figures below are illustrative, built from the typical ranges in this guide for a residential remodeling contractor with 3 employees, 2 pickup trucks, $600,000 of revenue, and $75,000 of tools.
| Policy | How the figure is worked out | Annual cost |
|---|---|---|
| General liability | Mid-range for a residential general contractor | $2,400 |
| Workers’ compensation | Payroll $135,000 divided by 100, times $6.50 class rate, times 1.0 modifier | $8,775 |
| Commercial auto | 2 light pickups at $2,400 each | $4,800 |
| Tools and equipment | About 1.2 percent of $75,000 of equipment value | $900 |
| Total | $16,875 |
The total is $16,875 a year, about $1,406 a month, or 2.8 percent of revenue. Workers’ compensation is the largest line, as usual for a contractor with employees.
How to choose your coverage limits
- Start with what is required. Check your state licensing rules and the insurance clause in your next contract. Those set your floor.
- Match limits to the worst realistic loss. If you work in occupied homes, $1 million per occurrence is the usual starting point; commercial work may call for $2 million.
- Consider an umbrella policy. A commercial umbrella adds a layer of liability above your general liability and auto limits.
- Price the same package three times. Give each carrier the same limits, deductibles, payroll, and revenue figures.
- Review the program once a year. Hire your first employee, buy a second truck, or take on a bigger project, and your old limits may no longer fit.
When you compare quotes, look past the premium: check the deductible, the exclusions, completed operations cover, and whether subcontractors must carry their own policies.
Common mistakes
- Buying general liability only. It covers neither your employees, your vehicles, nor your tools.
- Calling workers independent contractors to skip workers’ compensation. Misclassification is a common audit finding and can lead to back premiums and penalties.
- Using a personal auto policy for work driving. A business-use claim can be denied outright.
- Underinsuring tools. A trailer of tools can be worth more than a year of general liability premiums.
- Choosing the cheapest limits. A $500,000 limit saves little and leaves you exposed the moment a claim passes it.
- Forgetting the certificate of insurance. Many jobs cannot start until the client has it, so keep it current.
- Never updating the program. A policy written for last year’s payroll, vehicles, and equipment may not cover this year’s business.
Pros and cons
Pros: Insurance protects the business and your personal assets from claims that could otherwise close the company. It lets you bid on jobs that require proof of coverage, meets licensing and contract requirements, and turns an unpredictable risk into a fixed monthly cost.
Cons: Premiums are a real ongoing cost, especially workers’ compensation for crews. Policies have gaps and exclusions, and a claim can raise future premiums.
Frequently asked questions
Do I need contractor insurance if I work alone?
Yes. Working alone removes the workers’ compensation requirement in most states, not the risk of injuring a client, damaging a home, or losing your tools. Most clients still ask for a certificate.
Does general liability cover my tools?
No. General liability covers damage you cause to others’ property, not your own. Tools are covered by a separate policy, often called inland marine insurance, which follows your gear to job sites and in transit.
How fast can I get covered?
General liability and tools cover can often be bound the same day you apply. Workers’ compensation usually takes a few days, because the carrier needs payroll and class code details.
Can I pay monthly instead of annually?
Yes. Most carriers offer monthly plans, though they usually add a small installment fee. Paying annually is cheaper, but monthly keeps cash flow steadier.
Does my insurance cover subcontractors I hire?
Not automatically. Your policy may cover subcontractors only if they are named on it, and many general contractors require every subcontractor to carry their own cover. Collect a certificate from each subcontractor before they start work.
Bottom line
Contractor insurance is a cost of doing business, not an optional extra. Start with general liability, add workers’ compensation the moment you hire, insure every work vehicle commercially, and cover the tools that earn your living. Get three quotes on the same limits and review the program yearly as the business grows.
