Most subcontractors need at minimum general liability insurance and workers' compensation — and many GC contracts require both before you set foot on a job site. Depending on your trade, you may also need commercial auto, tools and equipment coverage, and an umbrella policy. Who this is for: subcontractors in construction, trades, and specialty contracting bidding on commercial or residential projects.
TL;DR — Key Takeaways
- General liability (GL) is the baseline: it covers third-party bodily injury and property damage you cause on a job site.
- Workers' compensation is legally required in nearly every state the moment you have employees; some states require it even for sole proprietors in certain trades.
- Commercial auto is mandatory if any vehicle is used for business purposes — personal auto policies exclude business use.
- Tools and equipment / inland marine coverage protects gear worth thousands of dollars that GL specifically excludes.
- GC contracts and project owners routinely require minimum limits, additional insured endorsements, and waivers of subrogation — missing any one of them can get you pulled off a job.
What Types of Insurance Do Subcontractors Typically Need?
| Coverage | What It Covers | Who Typically Requires It |
|---|---|---|
| General Liability (GL) | Third-party bodily injury, property damage, completed operations | GCs, project owners, licensing boards |
| Workers' Compensation | Medical bills + lost wages for injured employees; employer's liability | State law (varies); GC contracts |
| Commercial Auto | Accidents involving business-use vehicles | State law (minimum liability); GC contracts |
| Tools & Equipment / Inland Marine | Theft, damage, or loss of owned tools and portable equipment | Optional but strongly recommended |
| Commercial Umbrella / Excess | Extends limits above GL, auto, and employer's liability | GC contracts on larger projects |
| Professional Liability (E&O) | Design errors or faulty specifications (design-build subs) | Owners on design-build projects |
| Pollution Liability | Releases of pollutants during operations (HVAC, remediation, abatement) | GC contracts; environmental projects |
How Much Does Subcontractor Insurance Cost?
Cost depends on your trade, annual revenues (or payroll for workers' comp), claims history, and the states you work in. The figures below are illustrative starting points for a small subcontractor with no major prior claims.
| Trade / Specialty | GL Estimate (Annual) | WC Rate (Per $100 Payroll) | Commercial Auto (Per Vehicle/Year) |
|---|---|---|---|
| Framing / carpentry | $1,800 – $4,500 | $8 – $18 | $1,500 – $3,500 |
| Electrical | $1,200 – $3,800 | $5 – $12 | $1,500 – $3,200 |
| Plumbing | $1,500 – $4,200 | $6 – $14 | $1,500 – $3,200 |
| HVAC | $1,600 – $4,000 | $5 – $11 | $1,600 – $3,500 |
| Drywall / plastering | $2,000 – $5,500 | $9 – $20 | $1,400 – $3,000 |
| Roofing | $4,000 – $12,000+ | $18 – $40+ | $2,000 – $5,000 |
| Painting (interior) | $900 – $2,800 | $5 – $10 | $1,300 – $2,800 |
| Concrete / masonry | $2,200 – $6,000 | $8 – $18 | $1,500 – $3,500 |
These are illustrative ranges, not quotes. Your actual premium depends on your specific payroll, revenues, loss history, state, and carrier. Request a bindable quote for accurate pricing.
What Limits Do GC Contracts Usually Require?
Understanding what GCs ask for is just as important as knowing what policies to buy.
Common GC-Required Limits
| Coverage | Typical Minimum Limit | Common Higher Requirement |
|---|---|---|
| GL — Per Occurrence | $1,000,000 | $2,000,000 |
| GL — General Aggregate | $2,000,000 | $4,000,000 |
| GL — Products/Completed Operations Aggregate | $2,000,000 | $4,000,000 |
| Workers' Comp — Coverage | Statutory | Statutory |
| Employer's Liability (EL) | $100,000 / $100,000 / $500,000 | $500,000 / $500,000 / $500,000 |
| Commercial Auto — Combined Single Limit | $1,000,000 | $1,000,000 |
| Umbrella / Excess | $1,000,000 | $5,000,000+ |
GC contracts almost always require: - Additional insured (AI) status for the GC and project owner on your GL and auto policies - Waiver of subrogation on GL, auto, and workers' comp - Primary and non-contributory wording on the GL additional insured endorsement - 30-day notice of cancellation (sometimes 10 days for non-payment)
Is Workers' Compensation Required for Subcontractors?
Workers' compensation laws vary by state, but the short answer is: almost certainly yes if you have employees, and possibly yes even if you are a sole proprietor or single-member LLC.
Key rules to know:
- Most states require workers' comp the moment you hire your first W-2 employee. A handful allow small employers (typically 2–4 employees) to elect coverage. [verify state for exact threshold]
- Sole proprietors and partners are often excluded from their own workers' comp policy by default but may elect to include themselves — and many GC contracts require them to carry coverage or sign an exclusion form.
- 1099 subcontractors you hire: If a sub you bring on does not have their own workers' comp policy, most states treat them as your employees for workers' comp purposes, exposing you to liability. Always collect certificates from lower-tier subs.
- Texas is the only state that does not mandate workers' comp for most private employers, though many project owners require it contractually regardless.
How to Get Insured as a Subcontractor — 6 Steps
- Gather your business details. Pull together your trade classification, estimated annual revenues, total payroll, number of employees, and any current or prior claims. Underwriters price off these figures.
- Read your contracts before you buy. Get the insurance requirements section from your GC or project owner. This tells you exactly which coverages, limits, endorsements, and wording you need — buying before you read can leave you with non-compliant policies.
- Work with a commercial-lines broker. A broker who specializes in contractors can shop multiple carriers simultaneously, match your contract requirements, and flag gaps (e.g., a GL policy with a residential exclusion when you work on homes).
- Bind the policies. Your broker issues a binder confirming coverage is in force. Workers' comp typically starts immediately; GL often binds same-day.
- Request your Certificate of Insurance (COI). Instruct your broker to name the GC and owner as additional insureds and attach the proper waivers of subrogation. A well-run agency issues COIs within hours, not days.
- Submit the COI and review annually. Deliver the COI to the GC before mobilization. Set a calendar reminder 60 days before your policy renewal to review limits, update payroll estimates, and verify your experience mod (EMR) — premium-audit true-ups happen at renewal, and under-reported payroll creates surprise bills.
Real-World Example: An Electrical Subcontractor Bids a Commercial Office Fit-Out
This is an illustrative scenario, not a guarantee of outcomes.
Profile: A 4-person electrical subcontracting LLC in suburban Georgia. Annual revenues of $480,000; total payroll of $220,000. They are bidding on a commercial tenant improvement project where the GC requires $2M per-occurrence GL, $4M aggregate, $1M commercial auto CSL, and a $2M umbrella.
Estimated annual premium package:
| Policy | Estimated Annual Premium |
|---|---|
| General Liability ($2M/$4M, occurrence form) | ~$3,200 |
| Workers' Compensation (GA class 5190, ~$7.00/$100 payroll) | ~$15,400 |
| Commercial Auto (2 vans, $1M CSL) | ~$4,800 |
| Umbrella ($2M xs GL/Auto/EL) | ~$1,600 |
| Tools & Equipment ($40,000 limit) | ~$600 |
| Total Package | ~$25,600/year |
The GC's AI endorsement and waiver of subrogation are added at no charge by the carrier. The broker issues the COI the same afternoon the policies bind, and the sub is cleared to mobilize the following Monday. When an apprentice sprains an ankle on a ladder two months in, workers' comp covers the ER visit and lost wages — the GC's project timeline is unaffected and no GL claim is filed.
FAQ: Subcontractor Insurance
Q: Can I just be added to the GC's insurance instead of buying my own? No. A GC's policy covers the GC's operations and may extend additional insured status to subs, but it does not replace your own GL, workers' comp, or auto coverage. In a claim, coverage disputes between the GC's and your carrier can leave you personally exposed. Nearly all GC contracts require you to carry your own primary coverage.
Q: Does general liability cover my tools and equipment? No. Standard GL policies exclude damage to your own property. Tools and portable equipment are covered under an inland marine / tools and equipment policy or a scheduled equipment floater. Standard GL also excludes damage to property in your care, custody, or control (e.g., materials you are installing).
Q: What is a "completed operations" claim and why does it matter for subs? Completed operations is the portion of your GL that applies after you finish a job. If faulty electrical work you completed causes a fire six months later, that claim falls under completed operations, not your general operations coverage. Many carriers write this as a separate aggregate — confirm it is not shared with your general aggregate.
Q: Do I need workers' comp if I have only 1099 subcontractors? Possibly. State workers' comp laws determine whether a 1099 worker is truly an independent contractor or a statutory employee. If the sub lacks their own workers' comp policy, most states will treat them as your employee in a claim. Protect yourself by collecting a current COI from every sub you hire and ensuring they have active workers' comp.
Q: What is an experience modification rate (EMR) and how does it affect my premiums? The EMR (also called experience mod) compares your actual workers' comp losses to the expected losses for your trade over a 3-year lookback period. An EMR of 1.0 is average. An EMR below 1.0 reduces your premium; above 1.0 increases it. Many GCs disqualify subs with an EMR above 1.25. A strong safety program and prompt claim reporting are the primary levers for keeping your EMR low.
Q: How quickly can I get a certificate of insurance? With a properly structured policy in place, a COI can typically be issued within minutes to a few hours of request. The bottleneck is usually the first bind, not subsequent certificate issuance. At Morrow, certificates are issued the same business day in most cases.
Q: Does my personal auto insurance cover my work van? No. Personal auto policies contain a business-use exclusion. If you are in an accident driving to or from a job site in a vehicle titled to your business, or regularly hauling tools and materials, you need a commercial auto policy. Using a personal policy for business use is grounds for a coverage denial.
Q: Do I need professional liability as a subcontractor? Most trade subs do not — GL's completed operations covers faulty workmanship claims. However, if you provide any design services, stamped drawings, specifications, or consulting as part of your scope (design-build electrical layout, MEP coordination, etc.), professional liability (errors and omissions) fills the gap. GL specifically excludes professional services.

- Workers' comp expertise. Proper class-code assignment and payroll segregation directly affect your premium. Morrow's team reviews codes annually at renewal and flags audit exposure before it becomes a surprise bill.
- Claims advocacy. When a claim happens, you get a real person helping navigate the process — not a 1-800 number. We work on your behalf with adjusters to keep claims from inflating your EMR unnecessarily.
