If you're a general contractor, you need five core insurance policies: general liability, workers' compensation, commercial auto, builder's risk, and professional liability. Most states require proof of at least two or three of these before you can pull a license or sign a contract.
Costs vary by company size, crew, and project type. A solo contractor might pay $3,000 to $6,000 a year in total premiums. A mid-sized firm with employees and vehicles can easily spend $15,000 to $40,000 or more.
They cover risks like property damage, injuries, and medical costs. Insurance helps contractors and business owners stay compliant and financially safe. Every contractor needs proof of coverage before starting work. We call this proof a certificate of insurance. Requirements change by state and project type. The sections below explain each policy and its limits.

Contractor Insurance Types and Coverage
Contractor Liability Insurance
General liability insurance is the base coverage for contractors. It covers bodily injury, property damage, and medical expenses that may happen at job sites. For business owners, this insurance protects them against lawsuits and often serves as a requirement for contracts. Knowing what is contractor liability insurance helps you see how insurance protects both contractors and clients.
Workers’ Compensation
Most states require workers' compensation insurance by law. It pays for employee injuries, medical bills, and lost wages. Contractors need this policy to protect their team and their company from big claims. Without it, an insurance company may not provide support after an accident.
Commercial Auto Insurance
You need automobile liability if you use trucks, vans, or other vehicles for work. It pays for damages or injuries from business-related accidents. Contractors with fleets or even one work truck must carry this business insurance to stay compliant.
Builder’s Risk Coverage
Builder’s risk insurance protects active projects. It covers materials, equipment, and structures against fire, theft, or storms. For renovations or new builds, this policy helps protect your business from unexpected costs.
Umbrella and Specialty Policies
An umbrella policy adds extra protection above normal limits. Specialty coverages like errors and omissions or pollution insurance handle special risks. Large contracts or complex projects often require these types of insurance.
What Does Contractors’ Insurance Cover?
Contractor insurance coverages vary, but usually include property damage, bodily injury, defense costs, and payouts for accidents. General liability insurance covers third-party claims, while workers' comp protects employees. Together, these policies keep a business running even after an accident.
Required Insurance Limits for Contractors
Minimum General Liability Insurance
Most contracts require at least $1 million per occurrence in general liability. Larger projects may need higher limits. Business owners should always check contract terms before signing.
Workers’ Comp and Employer’s Liability
Employers’ liability goes with workers' comp and covers lawsuits for workplace injuries. Limits often range from $500,000 to $1 million. These protections are critical for contractors managing teams on job sites.
Auto and Professional Liability
Commercial auto policies often require $1 million in automobile liability. Professional liability insurance, also called errors and omissions, protects against mistakes in design or oversight. Both are vital when projects involve vehicles or planning work.
Legal and Compliance Requirements
Does a General Contractor Need Insurance?
Yes. Most states require contractors to carry insurance to work legally. Insurance also protects clients and contractors from financial risk. Having the right policies shows professionalism and reliability.
Many clients ask if a general contractor can do plumbing. This is because licensing and insurance rules depend on the type of work.
State Requirements (NJ, NY, Virginia Example)
In New Jersey and New York, contractors must obtain general liability insurance and workers' comp to receive their licenses. Virginia also requires proof of coverage with specific limits. While rules differ, all states expect insurance that protects your business and the public.
Certificates of Insurance and Subcontractors
A certificate of insurance proves coverage and requires submission before any work begins. Contractors should also ask subcontractors for COIs to confirm compliance. David Haziza, Owner and Master of Construction at A2Z Construction, warns that hiring uninsured subcontractors creates serious risks.
Contractor Insurance Costs and Bonds
How Much Does Contractor Insurance Cost?
Here's what contractors typically pay in 2026:
- General liability: $800 to $3,000/year for a solo contractor. Firms with employees or larger project volumes often pay $5,000 to $15,000+/year.
- Workers' compensation: Rates are calculated per $100 of payroll. Expect $2 to $10 per $100 depending on the trade and state. A crew with $200,000 in payroll could pay $4,000 to $20,000/year.
- Commercial auto: $1,500 to $3,000/year per vehicle for a standard work truck.
- Builder's risk: Usually 1% to 4% of the total project value. A $300,000 renovation project might cost $3,000 to $12,000 to insure.
- Professional liability (E&O): $1,000 to $3,000/year for most residential contractors.
- Umbrella policy: $500 to $2,000/year for an additional $1 million in coverage above your existing limits.
In New Jersey and New York, premiums run higher than national averages due to labor costs and local liability exposure. A residential contractor working in Bergen County with a small crew should budget at least $8,000 to $15,000/year in total insurance costs.
Contractor Bond Requirements vs Insurance
These are two different things, and you often need both.
A contractor bond (also called a license or surety bond) protects the client if you fail to complete work or violate licensing terms. Bond costs are low, typically $100 to $500/year for a $10,000 to $25,000 license bond. Performance bonds for larger projects typically range from 1% to 3% of the contract value.
Insurance covers accidents, injuries, and property damage. A bond covers non-performance and legal violations. If your contract or state license requires both, carry both.
Insurance for Independent Contractors
Independent contractors also need coverage to protect against claims. General liability insurance handles third-party risks, and workers' compensation insurance may apply if they hire help. Carrying coverage builds trust with clients and shows you can protect your business.
Risks of Hiring an Uninsured Contractor
Hiring a contractor without insurance puts both homeowners and business owners at risk. If accidents happen, the client may have to pay for medical expenses or repairs. Always ask for a certificate of insurance before work starts.

Why Insurance Requirements Matter
Protecting Contractors and Clients
Insurance protects contractors from financial losses and gives clients peace of mind. The right insurance coverages reduce disputes and keeps projects moving forward.
Meeting Legal and Contract Standards
Contracts often list required policies, and states enforce minimum standards. Following these insurance requirements for contractors keeps projects compliant and helps protect your business from penalties.
