One Gap in Coverage Cost Him Everything
Picture a framing contractor in Phoenix, eleven years in. Good crew. Steady referrals. Solid reputation. He carried general liability because the GC required it, but he skipped commercial auto and let his workers comp lapse to save $400 a month.
One afternoon, his crew lead rear-ended a sedan while hauling materials in the company truck. The other driver went to the ER. The framing contractor filed a claim on his personal auto policy. Denied. Business use exclusion. Then the injured crew member from the truck filed a workers comp claim. No active policy. The contractor was personally liable for medical bills, lost wages, and legal defense.
By the end of it, the lawsuits and medical costs totaled over $180,000. He lost the truck, drained his savings, and closed the business within a year. Eleven years of work wiped out by two policies he thought he could skip.
THE REALITY
Insurance is not paperwork. It is the wall between your business and financial ruin. This guide walks through every policy a contractor should understand, what each one actually covers, what it costs, and what happens when you skip it.
General Liability: The Non-Negotiable Policy
General liability insurance is the foundation of every contractor’s coverage. If you carry only one policy, this is it. It covers third-party bodily injury, property damage, and personal or advertising injury claims that arise from your work.
What it covers:
- A homeowner trips over your materials and breaks a wrist
- Your crew damages existing flooring while installing cabinets
- A subcontractor’s work causes a water leak that ruins a client’s furniture
- A competitor claims you made false statements about their business
What it does not cover:
- Injuries to your own employees. That is workers comp.
- Damage to your own tools and equipment. That is inland marine.
- Vehicle accidents. That is commercial auto.
- Faulty design advice. That is professional liability.
Most policies are written with a $1,000,000 per occurrence limit and a $2,000,000 aggregate. For small to mid-size contractors, premiums typically run $500 to $3,000 per year, depending on trade, revenue, employee count, and claims history. High-risk trades like roofing, demolition, and structural work pay more.

WHY IT IS NON-NEGOTIABLE
Nearly every GC, property owner, and commercial client requires a certificate of insurance showing active general liability before you step foot on their site. No GL policy means no jobs. Period.
Workers Compensation: Protecting Your Crew and Yourself
Workers comp covers medical bills, lost wages, and rehabilitation costs when an employee is injured on the job. In construction, it is not optional in most states. Texas is the only state where private employers can opt out entirely, and even there, going without it creates massive legal exposure.
State requirements vary significantly:
- California requires contractors in certain trades, including roofing, concrete, and HVAC, to carry coverage even with no employees, and every licensed contractor in the state must carry it by January 1, 2028. New York exempts sole proprietors with no employees, but most GCs will still require a certificate before you work as a sub
- Florida requires it for any construction company with one or more employees
- Several states set a general threshold of three to five employees, and some drop that threshold to a single employee for construction work
- Some states allow sole proprietors and partners to exempt themselves, but that means your own injuries are not covered
How premiums work: Workers comp rates are based on classification codes that reflect the risk level of the work. A roofer pays far more for every $100 of payroll than an electrician. Rates vary widely by state and carrier, but as rough ballparks:
- Carpentry: $5 to $15 for every $100 of payroll
- Roofing: $15 to $40 for every $100 of payroll
- Electrical: $3 to $8 for every $100 of payroll
- Plumbing: $4 to $10 for every $100 of payroll
- General contracting: $8 to $20 for every $100 of payroll
For a framing crew with $300,000 in annual payroll at a rate of $12 for every $100, that is $36,000 per year. Expensive, yes. But a single serious injury without coverage could cost ten times that in medical bills, legal fees, and state penalties.
CONSEQUENCES OF SKIPPING
Operating without required workers comp is a criminal offense in many states. Penalties include fines up to $100,000, stop-work orders that shut down your job sites, and personal liability for all medical costs. In California, it is a misdemeanor punishable by up to one year in jail and a fine of at least $10,000.
Commercial Auto: Your Personal Policy Will Not Cover You
This is the coverage gap that catches contractors off guard more than any other. Your personal auto policy has a business use exclusion. If you are driving to a job site, hauling materials, or have your company name on the vehicle, a personal policy will likely deny the claim. It does not matter that you have been paying premiums for years.
Commercial auto covers:
- Liability for accidents where you are at fault
- Damage to your vehicle, including collision and comprehensive
- Medical payments for you and passengers
- Uninsured or underinsured motorist protection
- Hired and non-owned auto for employees using personal vehicles for work
What you need to know about cost: A commercial auto policy for a single work truck typically runs $1,200 to $3,000 per year. A fleet of five vehicles might run $5,000 to $12,000 depending on driver records, vehicle types, and coverage limits. That sounds steep until you consider what a single at fault accident with an injury can cost once medical bills, vehicle damage, and legal fees stack up.
Hired and non-owned auto is a critical add-on that many contractors overlook. If your employee runs an errand in their personal car and causes an accident while on company business, your business can be named in the lawsuit. This endorsement covers that gap and typically costs $150 to $500 per year.

QUICK TEST
Call your personal auto insurer and ask: “Am I covered if I am in an accident while hauling materials to a job site?” If the answer is no, or if they hesitate, you need commercial auto. Do not wait for the accident to find out.
Builder’s Risk and Inland Marine: Covering the Job and Your Gear
These two policies are often confused, but they cover different things. You may need one or both depending on the work you do.
Builder’s Risk Insurance
Builder’s risk covers the structure under construction and the materials on site during the build. It protects against fire, wind, theft, vandalism, and other covered perils. The policy starts when construction begins and ends when the project is complete or the building is occupied.
- Typically purchased per project, especially for new construction and major renovations
- Premiums are priced as a fraction of the total project value and vary with location, construction type, and project length
- A $500,000 residential build might cost $2,500 to $10,000 for the policy
- The GC, owner, or both may carry it depending on the contract terms
Inland Marine Insurance, Also Called Tools and Equipment Coverage
Inland marine covers your tools, equipment, and materials while they are in transit or stored at job sites, warehouses, or your truck. General liability does not cover your own property. If someone steals $15,000 worth of tools from your truck, GL will not pay for it. Inland marine will.
- Covers tools, portable equipment, and materials in transit
- Works regardless of location, including job site, truck, storage unit, or your garage
- Premiums typically run 1% to 3% of the total value of covered equipment
- A $50,000 tool inventory might cost $500 to $1,500 per year to insure
PRO TIP
Keep a detailed inventory of every tool and piece of equipment with serial numbers, photos, and purchase receipts. Update it quarterly. If you file a claim and cannot prove what you owned, the payout will be a fraction of the actual loss. The separate SimplyWise Receipt Scanner can help file tool receipts into expense categories, but your insurance inventory still needs serial numbers and photos.
Professional Liability and Errors and Omissions
If your work includes any design, consulting, project management, or professional advice, general liability is not enough. GL covers physical damage. Professional liability, also called errors and omissions, covers claims arising from your professional services and advice.
Who needs it:
- Design-build contractors who handle both design and construction
- Construction managers and project managers
- Contractors who provide consulting or feasibility assessments
- Firms that stamp drawings or sign off on engineering decisions
- Any contractor whose contract includes “professional services” language
What it covers:
- Design errors that lead to structural problems or code violations
- Incorrect cost projections that cause a client financial loss
- Failure to meet a professional standard of care
- Missed deadlines caused by professional oversight
- Legal defense costs even if the claim has no merit
Premiums vary widely based on your revenue, services, and claims history. Small design-build firms typically pay $1,500 to $5,000 per year for $1M in coverage. Larger firms with higher risk profiles can pay $10,000 to $30,000 or more.
THE GAP THAT GETS PEOPLE
A client sues because your design recommendation led to a foundation issue. You call your GL carrier. They decline the claim because it stems from professional advice, not physical damage. Without errors and omissions coverage, you are paying for legal defense and any settlement out of pocket.
Umbrella Policy: Extra Coverage When Standard Limits Are Not Enough
An umbrella policy sits on top of your existing liability policies, including GL, commercial auto, and workers comp employer’s liability, and kicks in when a claim exceeds the underlying policy limits. Think of it as a safety net for your safety nets.
When you need one:
- Your GL limit is $1M but you work on projects where a single accident could exceed that
- You have significant personal assets, including a home, savings, or investments, that a judgment could reach
- You work on commercial or government projects that require higher limits
- Your contract requires $5M or more in coverage
- You have a fleet of vehicles and multiple crews in the field
Cost and structure: Umbrella policies are sold in $1M increments, starting at $1M. Premiums for a $1M umbrella typically run $500 to $1,500 per year for a small contractor. A $5M umbrella might cost $2,000 to $5,000. That is remarkably affordable for the amount of protection it provides.
The key requirement is that you must carry the minimum underlying limits required by the umbrella carrier. If they require $1M/$2M GL and $1M commercial auto, you cannot buy cheaper underlying policies to save money and expect the umbrella to fill the gap.
REAL MATH
A $2M umbrella policy at $1,200 per year gives you $3M in total GL coverage. That is $100 a month for an extra $2M in protection. For a contractor with a home, a retirement account, and a family to protect, this is one of the highest-value policies available.
How Much Coverage Do You Actually Need?
There is no single answer, but there are clear guidelines based on your trade, revenue, and business structure.
Solo trade contractor, under $250K revenue and no employees:
- General liability: $1M/$2M, required by nearly every GC
- Commercial auto: $1M combined single limit
- Inland marine: coverage equal to total tool value
- Workers comp: check your state requirements for sole proprietors
- Estimated annual cost: $3,000 to $7,000
Small GC with a crew, 3 to 10 employees and $500K to $2M revenue:
- General liability: $1M/$2M minimum
- Workers comp: mandatory in most states
- Commercial auto: $1M combined single limit plus hired and non-owned
- Inland marine: $50K to $150K in tool and equipment coverage
- Umbrella: $1M to $2M
- Estimated annual cost: $15,000 to $50,000 depending on trade and payroll
Mid-size contractor, 10+ employees, $2M+ revenue, and commercial projects:
- All of the above plus higher limits
- Professional liability if doing any design-build
- Builder’s risk per project
- Umbrella: $5M or more
- Estimated annual cost: $50,000 to $150,000+
PRACTICAL ADVICE
Work with an insurance broker who specializes in construction. A generalist agent who mostly writes homeowner and auto policies will not understand classification codes, audit procedures, or contract insurance requirements. A construction-focused broker will also know which carriers are competitive for your specific trade.
Five ways to lower your premiums without cutting coverage:
- Bundle policies. A Business Owner’s Policy or contractor package combines GL, property, and inland marine at a discount.
- Maintain a clean claims history. Carriers reward contractors who have not filed claims in three to five years.
- Document your safety program. A written safety program with regular training, documented toolbox talks, and incident tracking can earn premium credits.
- Shop every renewal. Get at least three quotes. Loyalty does not lower rates in commercial insurance.
- Pay annually. Paying by installment often adds fees that increase the total cost by 5% to 10%.

Frequently Asked Questions
How much does general liability insurance cost for a contractor?
General liability premiums typically range from $500 to $3,000 per year for a small operation, depending on your trade, revenue, number of employees, claims history, and coverage limits. High-risk trades like roofing and demolition pay more. A $1M/$2M policy is standard. Many contractors pay between $80 and $250 a month.
Can I use my personal auto insurance for my work truck?
No. Personal auto policies exclude vehicles used for business purposes. If you haul materials, drive to job sites, or have your company name on the truck, a personal policy will likely deny the claim. You need a commercial auto policy. Some insurers offer a hybrid endorsement for trucks used both personally and for work, but a standalone commercial policy is the safest option.
Is workers comp required if I am a solo contractor with no employees?
It depends on your state. Most states, including New York, do not require a sole proprietor with no employees to carry workers comp, though you can cover yourself voluntarily. California requires certain trades, such as roofing and concrete, to carry it even with no employees, and will require it of every licensed contractor by January 1, 2028. Even where it is not required, many GCs will not hire you as a sub without a workers comp certificate. Carrying it also protects you personally if you are injured on the job.
What is the difference between builder’s risk and inland marine insurance?
Builder’s risk covers the structure being built and the materials on site during construction. It ends when the project is complete. Inland marine covers your tools, equipment, and materials in transit or stored at various locations. Think of builder’s risk as protecting the project and inland marine as protecting your stuff. Most contractors need both.
How do I lower my construction insurance premiums?
Bundle multiple policies with one carrier. Maintain a clean claims history. Implement and document a written safety program. Increase your deductible if cash flow allows. Shop at least three carriers every renewal cycle. Classify employees correctly, since a misclassified roofer billed as a painter will trigger an audit surcharge. Pay annually instead of paying by installment to avoid fees.
Do I need professional liability insurance as a general contractor?
If your work includes any design, consulting, project management, or professional advice, yes. Professional liability, also called errors and omissions, covers claims arising from your professional services, not physical damage. General liability will not cover a claim that your design recommendation caused a structural issue. If you are strictly a trade contractor who builds to someone else’s plans, you may not need it, but any design-build work makes it essential.
