1. General Liability Insurance
General liability (GL) insurance is the foundation of contractor insurance. It covers third-party bodily injury and property damage claims arising from your work. If a visitor trips over your materials on a job site or your work causes water damage to a client's home, GL covers the claim. Most states and clients require GL coverage with minimum limits of $1 million per occurrence and $2 million aggregate.
Key Points
- •GL covers third-party bodily injury and property damage claims from your operations
- •Standard minimums are $1 million per occurrence and $2 million aggregate
- •GL does not cover your own injuries, your employees, or damage to your own work
2. Workers Compensation Insurance
Workers compensation insurance covers medical expenses and lost wages for employees who are injured on the job. In most states, any contractor with employees is required to carry workers comp. Even in states where it is optional for small employers, having it protects you from potentially devastating injury lawsuits. Rates vary significantly by trade classification.
Key Points
- •Workers comp is required in almost every state once you have even one employee
- •Rates are based on your trade classification, payroll, and claims history
- •Roofing and structural steel have the highest rates while office workers have the lowest
3. Bonds and Bonding
Contractor bonds come in several types. A license bond is required by your state or local licensing board. A bid bond guarantees you will honor your bid if selected. A performance bond guarantees you will complete the work. A payment bond guarantees you will pay your subs and suppliers. Bonding capacity is based on your financial statements, experience, and credit.
Key Points
- •License bonds are typically small ($5,000-25,000) and are required for licensing in many states
- •Performance and payment bonds are common on commercial and government projects and usually cost 1-3% of the contract amount
- •Building your bonding capacity requires strong financial statements, a track record of completed projects, and good credit
4. Additional Coverage Types
Beyond GL, workers comp, and bonds, contractors should consider commercial auto insurance for work vehicles, inland marine or tools and equipment coverage, builders risk insurance for projects under construction, umbrella or excess liability for additional limits, and professional liability if you provide design services. Work with an agent who specializes in construction to build the right program.
Key Points
- •Commercial auto is required for any vehicle used for business purposes and personal auto policies exclude business use
- •Builders risk covers the structure under construction against fire, theft, and weather damage
- •An umbrella policy provides additional limits above your GL and auto policies and is relatively inexpensive

- ★Many general contractors require subcontractors to carry $1-2 million in GL coverage and name the GC as an additional insured on the policy.

Knowledge Check
1. A general contractor asks you to provide a certificate of insurance naming them as an additional insured. What does this mean and why do they want it?
2. You are a sole proprietor with no employees. Do you need workers compensation insurance?

Common questions about this topic
Maintain a clean claims history, implement a safety program, shop quotes from multiple carriers every 2-3 years, increase your deductible if you have cash reserves, and bundle policies with one carrier for multi-policy discounts. Working with an agent who specializes in construction insurance usually gets better rates than going direct.
A gap in coverage means any incidents during that period are uninsured and you are personally liable. It can also affect your licensing status, your ability to pull permits, and your standing with clients and GCs. Most importantly, new policies may not cover claims for work done during the gap period.
