The Contractor’s Complete Insurance Guide: What Every Coverage Does, What It Misses, and What to Check Before Your Next Job

If you run a contracting business — whether you’re a one-person operation or managing a crew — your insurance needs are more complex than almost any other small business type. The work is physical, the exposure is high, and the gaps in standard policies are real.

This guide breaks down every major coverage a contractor should have. What each one covers, what it specifically does not cover, what to check on your existing policy, and a quick-audit checklist at the end to help you find the gaps before something else does.

Pull out your current policies and work through this section by section.

---

Coverage #1: General Liability Insurance

What it covers

• Third-party bodily injury — a homeowner or bystander hurt on your jobsite
• Third-party property damage — you or your crew damages a client’s home, structure, or belongings
• Products and completed operations — a claim that your work caused damage or injury after the job is done
• Legal defense costs when your business is sued by someone other than an employee
• Advertising injury — if a competitor claims your marketing damaged their business

What it does NOT cover

• Your own employees’ injuries — that’s workers’ compensation
• Your own tools, equipment, or materials — that’s inland marine
• Faulty workmanship itself — GL covers the damage caused by faulty work, not the cost to redo the work
• Vehicles used on the job — that’s commercial auto
• Work performed by subcontractors you hire — unless you specifically add them and verify their own coverage

What to check on your policy

• Does your policy include completed operations coverage? This is the coverage that responds when a client files a claim months or years after you finish a job — it’s a separate part of GL and sometimes excluded or underinsured
• What are your per-occurrence and aggregate limits? For contractors doing significant projects, $1M/$2M is the minimum — many commercial clients and GCs require higher
• Are subcontractors you hire covered, or do they need their own certificates? Verify before every job
• Does your policy specifically list the type of work you do? A roofing contractor and a painting contractor are rated very differently — misrepresenting your work type can result in denied claims

Coverage #2: Workers’ Compensation — The Deep Dive

Workers’ compensation is where most contractors either overpay, underpay, or get hit with a surprise audit bill. Understanding how it actually works saves real money.

What it covers

• Medical expenses when an employee is injured on the job — falls, cuts, burns, back injuries, equipment accidents
• Lost wages while an injured employee cannot work
• Rehabilitation and physical therapy costs
• Permanent disability benefits if an injury causes lasting impairment
• Death benefits to the family of an employee who dies from a work-related injury

What it does NOT cover

• Independent contractors — if someone is classified as a 1099 subcontractor, they are not covered under your workers’ comp
• Injuries that happen outside of work duties
• Injuries where the employee was under the influence at the time
• Intentional self-harm

Understanding class codes — this is where most contractors get it wrong

Workers’ compensation premiums are calculated based on two things: your payroll and your class code. Class codes are four-digit numbers assigned by NCCI (National Council on Compensation Insurance) that describe the type of work each employee does. Different work = different risk = different rate per $100 of payroll.

Common contractor class codes and what they mean:

• 5645 — Carpentry, residential construction not exceeding three stories. This is one of the most commonly misused codes — it only applies to artisan contractors doing only carpentry. If a carpenter is also doing other trades work on the same site, this code likely doesn’t apply.
• 5403 — Carpentry on commercial buildings or residential structures over three stories. Higher rate than 5645.
• 5537 — HVAC installation, service, and repair.
• 5606 — Project manager, construction superintendent, construction executive — office and supervisory duties only. One of the most commonly misclassified codes because it’s significantly cheaper than field codes. If a superintendent picks up a hammer even occasionally, this code doesn’t apply.
• 8810 — Clerical office employees. Very low rate, but the employee must be physically separated from the field work and cannot perform any field duties — ever.

The misclassification problem: Using a lower-rate code to save money is one of the most common audit findings. At the end of your policy year, insurance companies audit your actual payroll and verify that class codes match actual job duties. If there’s a mismatch, you get a bill — sometimes a very large one. Getting codes right upfront is always cheaper than correcting them at audit.

Experience modification rate (EMR) — know your number

Your EMR — also called your experience mod — is a multiplier that adjusts your workers’ comp premium based on your actual claims history compared to other contractors in your class. An EMR of 1.0 is average. Below 1.0 means fewer claims than average — you pay less. Above 1.0 means more claims — you pay more.

Many commercial GCs and government contracts require contractors to have an EMR below a specific threshold — often 1.0 or lower — to even bid on the job. Keeping your EMR down is both a safety and a business development issue.

What to check on your policy

• Pull your workers’ comp declarations page — are all class codes listed accurate for what your employees actually do?
• Is your payroll estimate current? Underreporting payroll = a larger audit bill at year end
• Do you know your current EMR? Ask your agent — it’s a number every contractor should know
• If you use subcontractors regularly, do you collect certificates of insurance from them? If a sub doesn’t have their own coverage and gets hurt on your site, your workers’ comp may be on the hook
• Are you required to carry workers’ comp in your state? In MN, ND, SD, IA, WI, and PA — yes, if you have employees

Coverage #3: Inland Marine — Tools, Equipment, and Heavy Machinery

This is the coverage most contractors don’t have — and the one they need most urgently.

Your commercial property policy covers what’s at your fixed business location. It does not follow your tools and equipment to the jobsite, into your truck, or to a storage yard across town. Inland marine — also called a contractor’s equipment floater or tools and equipment coverage — is what covers your assets everywhere else they go.

The construction industry loses an estimated $300 million to $1 billion per year to equipment theft alone. Most of that is uninsured or underinsured.

What it covers

• Hand tools and small power tools — drills, saws, nail guns, levels, meters
• Portable power equipment — generators, compressors, pressure washers
• Heavy mobile equipment — skid steers, mini-excavators, backhoes, loaders, forklifts
• Equipment while in transit between jobsites or to storage
• Equipment at the jobsite — including theft, vandalism, fire, and accidental damage
• Rented or leased equipment you’re responsible for (with proper endorsement)
• Employee-owned tools used for your business (with proper endorsement)
• Jobsite trailers and temporary storage containers
• Spare parts and supplies kept for equipment maintenance

What it does NOT cover

• Wear and tear or mechanical breakdown — that’s equipment breakdown coverage
• Vehicles licensed for road use — those go on your commercial auto policy
• Third-party liability from equipment use — that’s general liability
• Tools or equipment not listed or within your blanket limit
• Damage from improper maintenance or negligence in most policies

Scheduled vs. blanket coverage — how to structure it right

Most policies handle this two ways:

• Scheduled coverage — specific high-value items listed individually with their own limits. Recommended for any piece of equipment worth more than $1,500. Each item is insured for its listed value.
• Blanket coverage — a total limit that covers all smaller miscellaneous tools collectively. Good for hand tools and small equipment where individual scheduling isn’t practical.

The right approach for most contractors: schedule every piece of equipment over $1,500 individually, and set a blanket limit for everything smaller that’s high enough to cover a total loss of the truck if it gets stolen.

What to check on your policy

• Do you even have inland marine coverage? Many contractors assume it’s part of their GL or BOP — it usually isn’t
• Is your equipment inventory current? Equipment bought since you last reviewed your policy may not be covered
• Are serial numbers documented for all scheduled equipment? Claims process significantly faster with serial numbers and purchase records
• Does your policy cover rented equipment? If you rent a piece of equipment and it gets stolen or damaged on your site, who pays?
• Does coverage extend to equipment stored at a yard or storage facility away from your office?
• What’s the deductible? Higher deductibles reduce premium but can still hurt on a large theft claim

Installation floater — the piece most contractors miss

An installation floater covers building materials and supplies in transit or on the jobsite before they’re installed. If lumber gets stolen from a site, drywall is damaged in a storm before it goes up, or custom fixtures are destroyed before installation — an installation floater covers it. Standard property and GL do not. If you’re doing significant material-heavy projects, ask your agent specifically about installation floater coverage.

Coverage #4: Commercial Auto Insurance

What it covers

• Accidents involving business-owned vehicles — trucks, vans, trailers
• Liability to other drivers when a business vehicle is at fault
• Physical damage to your own vehicles (with comprehensive and collision added)
• Employees driving business-owned vehicles
• Towing and roadside assistance if added

What it does NOT cover

• Personal vehicles your employees use to get to and from work — those are covered by their personal auto
• Employees using personal vehicles for business purposes — this is a major gap (see below)
• Tools and equipment inside the vehicle — that’s inland marine
• Trailers not specifically scheduled on the policy

The hired and non-owned auto gap

If an employee drives their personal truck to pick up materials, haul equipment, or run a job-related errand and gets into an accident — their personal auto insurance will likely deny the claim because the vehicle was being used for business purposes. Your commercial auto won’t cover it either unless you have hired and non-owned auto (HNOA) coverage added.

HNOA is an endorsement — often inexpensive — that covers your liability when employees use personal vehicles for business tasks. Every contractor with employees who use their own vehicles for any work purpose needs this.

What to check on your policy

• Are all vehicles specifically listed on the policy with correct VINs?
• Are all drivers listed, and are their MVRs reviewed at least annually? A driver with recent violations affects your premium and your risk
• Do you have hired and non-owned auto coverage?
• Are your trailers scheduled? A trailer not listed may not be covered
• If you transport heavy equipment on flatbeds, is the equipment covered during transport — or does that fall to your inland marine policy?
• Do you have adequate liability limits? Minimum state limits are often inadequate for commercial operations

---

Coverage #5: Builder’s Risk Insurance

What it covers

• The structure under construction — from the foundation up, throughout the project
• Materials on the jobsite waiting to be installed
• Damage from fire, wind, lightning, vandalism, and theft of building materials
• Sometimes covers materials in transit to the jobsite
• Soft costs in some policies — architect fees, permits, additional interest on construction loans if the project is delayed by a covered loss

What it does NOT cover

• Tools and equipment — that’s inland marine
• Liability for injuries — that’s general liability
• Flood or earthquake damage unless specifically endorsed
• Faulty design or workmanship
• Normal wear, settling, or shrinkage

What to check on your policy

• Who is responsible for carrying builder’s risk — you or the property owner? This varies by contract and should be specified before the job starts
• Is the coverage limit equal to the completed value of the project — not just materials in place today?
• Does coverage extend to materials stored off-site or in transit?
• What’s the policy period — does it extend far enough to cover project delays?

Coverage #6: Disability Insurance — The One Contractors Almost Never Have

A contractor’s income depends entirely on their ability to physically work. There’s no sick leave. No HR department covering you. If you can’t work — whether it’s a torn rotator cuff, a back surgery, or a serious illness — your income stops. Your business expenses don’t.

Roughly one in four workers will experience a disabling illness or injury before retirement. For contractors doing physical work, that exposure is even higher.

Two types of disability coverage to understand

Individual disability income insurance — replaces a portion of your personal income (typically 50–70% of pre-tax income) if you can’t work due to illness or injury. Benefits are paid monthly for a specified period or until you recover.

Business overhead expense (BOE) disability insurance — covers your fixed business expenses while you’re disabled. Payroll, rent, utilities, equipment payments, insurance premiums — the bills that keep coming even when you can’t be on the job. This is separate from personal disability coverage and specifically designed for business owners who have employees and overhead to maintain.

Key terms that change everything

• Own-occupation definition — you qualify for benefits if you can’t perform the duties of your specific occupation. A roofer who can no longer do roofing but could theoretically do desk work would still collect under an own-occupation policy. This is the better definition for contractors.
• Any-occupation definition — you only qualify if you can’t do any work at all. Much harder to collect on. Less expensive, but significantly less protective for skilled tradespeople.
• Elimination period — the waiting period before benefits begin. 30, 60, 90, or 180 days. Longer elimination periods cost less but require more cash reserves to bridge the gap.
• Benefit period — how long benefits are paid. Two years, five years, or to age 65. For a contractor in their 40s, a two-year benefit period may not be enough.
• Non-cancelable and guaranteed renewable — the carrier cannot raise your premium or change your benefits as long as you pay. This is the gold standard for self-employed contractors.

What to check

• Do you have any disability coverage at all? Most self-employed contractors don’t
• If you were unable to work for 6 months, how long could you cover your business expenses and personal living costs?
• Does your policy use own-occupation or any-occupation definition?
• Is your benefit amount sufficient to cover both personal and business obligations?
• Do you have BOE coverage in addition to personal disability — or just one or the other?

Coverage #7: Retirement and Benefits Planning for Contractors

Most contractors put every dollar back into the business. Retirement planning gets pushed off until “things slow down.” They rarely do. Here’s what’s actually available — and the real numbers.

For solo contractors and owner-operators

SEP IRA (Simplified Employee Pension) — one of the easiest retirement vehicles for self-employed contractors. Contribute up to 25% of net self-employment income, up to $70,000 in 2025 and $72,000 in 2026. Contributions are tax-deductible, reduce your taxable income, and can be made as late as your tax filing deadline including extensions. No complex administration. No annual filing with the IRS. Easy to set up through any financial institution.

Solo 401(k) — for contractors with no full-time employees other than a spouse. You can contribute as both employee (up to $23,500 in 2025, $24,500 in 2026) and employer (up to 25% of compensation), for a combined total up to $70,000 in 2025. Also available with a Roth option — after-tax contributions with potentially tax-free withdrawals in retirement. Higher total contribution limits than a SEP IRA for many income levels.

For contractors with employees

SIMPLE IRA — designed for businesses with 100 or fewer employees. Employees can contribute up to $16,500 in 2025 (age 50+ catch-up: $3,500). Employer must either match up to 3% of employee compensation or contribute a flat 2% for all eligible employees regardless of their own contributions. Lower administrative burden than a full 401(k).

Group 401(k) — the most flexible option for growing contractor businesses with employees. Higher contribution limits, Roth options, loan provisions, and plan design flexibility. More administrative requirements and typically more expensive to maintain — but a significant recruiting and retention tool in a competitive labor market.

Benefits that help recruit and keep good crews

• Group health insurance — offering health coverage, even at partial employer contribution, is one of the strongest retention tools a contractor can use. Skilled tradespeople have options. Health benefits narrow your competition for good help.
• Group life insurance — typically inexpensive when bundled with other benefits. Provides meaningful protection for employees with families and costs the business very little.
• Group disability insurance — distinct from your personal disability coverage, this covers your employees if they can’t work. Workers’ comp covers on-the-job injuries — group disability covers illness and off-the-job injuries that workers’ comp doesn’t touch.

What to check

• Do you have any retirement savings vehicle in place? If not, what are you losing in tax-deferred growth each year you delay?
• Are you maximizing contributions? A solo contractor putting 25% of net income into a SEP IRA reduces their taxable income significantly
• Do you have employees who could be retained longer with a benefits package? The cost of turnover in the trades is substantial
• Is your retirement plan properly coordinated with your overall financial plan? Speak with a financial planner who understands self-employed and contractor-specific planning

Coverage #8: Umbrella / Excess Liability

What it covers

• Additional liability limits above your GL, commercial auto, and employers’ liability coverage
• Claims that exceed primary policy limits — the situations where a single judgment can wipe out a business
• Some umbrellas pick up certain gaps not covered by underlying policies

What to check

• Do you have an umbrella? For contractors doing significant commercial work or working on large residential projects, primary limits alone are often not enough
• Does your umbrella sit above all three primary coverages — GL, commercial auto, and employers’ liability?
• Does your contract require minimum umbrella limits? Many commercial GCs specify $5M or $10M total — check before you bid
