Subcontractor Insurance Requirements: What GCs Should Verify
Plain-English checklist for subcontractor insurance requirements general contractors should verify before work begins.

Key takeaway
Subcontractor insurance requirements should be verified before a subcontractor starts work, not after a certificate is requested by the project owner.
Quick Answer: Subcontractor insurance requirements should be verified before a subcontractor starts work, not after a certificate is requested by the project owner. General contractors should review workers' compensation, general liability, policy dates, endorsements, limits, exclusions, and whether the subcontract agreement matches the insurance paperwork.
If you hire subs, your own contractor insurance is only part of the risk picture. Ellie Insurance Group helps general contractors shop on your behalf, organize insurance paperwork, and shops 100+ carrier markets for best rates.
What Business Owners Need to Know
When a general contractor hires a subcontractor, the general contractor is usually responsible for the final project. If the subcontractor causes property damage, injures a third party, or has an employee injured on the jobsite, the general contractor can be pulled into the claim. Subcontractor insurance requirements exist to help make sure the subcontractor's insurance responds first, protecting the general contractor's policy and loss history.
The process starts with the subcontract agreement. The contract should clearly state what insurance the subcontractor must carry, what limits are required, what endorsements are needed, and when certificates must be provided. If the contract is silent on insurance, asking for a certificate later is much harder. The insurance requirements should match the risk of the trade. A framing contractor and a final-clean janitorial crew may not need identical limits, but both need clear requirements.
Workers' compensation is a critical requirement. In Florida, the Department of Financial Services states that contractors must make certain subcontractors have required workers' compensation before they begin work on a project.[1] If a subcontractor does not have the required coverage, the subcontractor's workers become the employees of the contractor for workers' compensation benefit purposes after a work-related injury, illness, or fatality.[1] That means a general contractor can end up paying for a subcontractor's injured employee if the paperwork is not verified.
General liability is the other foundational requirement. It helps address third-party bodily injury and property damage claims caused by the subcontractor's work. General contractors usually require the subcontractor to name the general contractor as an additional insured. This is not the same as just being a certificate holder. Additional insured status gives the general contractor certain rights under the subcontractor's policy if a claim arises from the subcontractor's operations.
Ellie Insurance Group is Florida-born, insuring businesses nationwide. Founded in 2022, the agency serves contractors from Tampa and Brooksville and shops 100+ carrier markets on your behalf. The agency understands that chasing subcontractor certificates is frustrating, but it is a necessary part of running a construction business. The goal is to help you build a clear insurance requirement checklist so you can focus on the project.
Coverage Details and Common Mistakes
A certificate of insurance (COI) is a summary, not a policy. A common mistake is accepting a COI without reading it or without asking for the actual endorsements. If the contract requires a waiver of subrogation or primary and noncontributory wording, the COI may check a box, but the policy must actually contain the endorsement to provide the coverage.
| Requirement | What it means | Common mistake |
|---|---|---|
| Additional Insured | Adds the GC to the sub's liability policy for certain claims | Accepting a certificate without the actual endorsement |
| Waiver of Subrogation | Prevents the sub's carrier from recovering costs from the GC | Assuming it applies to all policies automatically |
| Primary and Noncontributory | Makes the sub's policy respond first, without the GC's policy contributing | Forgetting to include the requirement in the subcontract |
| Workers' Compensation | Covers the sub's injured employees | Accepting an exemption without verifying it is valid for the trade |
| Completed Operations | Extends additional insured status after the work is done | Only requiring ongoing operations coverage |
Another mistake is ignoring policy dates. A subcontractor may provide a valid certificate in January for a project that runs through November. If the subcontractor's policy expires in June, the general contractor has an exposure gap from July to November unless a renewal certificate is collected. General contractors need a system to track expiration dates and request renewals before the old policy expires.
Exclusions are also a problem. A subcontractor may have a general liability policy, but it might exclude the exact work they are hired to do. For example, a roofing subcontractor might have a policy that excludes multi-family residential work, or a plumber might have a policy that excludes tract housing. If the project falls under an exclusion, the subcontractor effectively has no coverage for that job, and the general contractor's policy may have to respond.
General contractors should also be careful with workers' compensation exemptions. Florida allows certain corporate officers or LLC members in the construction industry to file for an exemption from workers' compensation.[1] However, an exemption only applies to the specific person who holds it, not to their employees or day laborers. If an exempt subcontractor brings a helper to the jobsite, that helper needs workers' compensation coverage.
Finally, do not forget commercial auto and umbrella requirements. If a subcontractor is driving heavy trucks onto the jobsite, commercial auto insurance is important. If the project is large or high-risk, the general contractor may require the subcontractor to carry an umbrella policy to provide higher liability limits. The requirements should fit the exposure.
For general contractors, Ellie Insurance Group can help review your own contractor insurance to make sure it aligns with your subcontractor management practices. The agency shops 100+ carrier markets for best rates, but the underwriting process will still ask how you manage your subcontractors.
How This Applies in Florida and Licensed States
Florida's workers' compensation rules for construction are strict. The requirement that construction employers with one or more employees must carry coverage means very few construction businesses are naturally exempt without filing specific paperwork.[1] General contractors in Tampa, Brooksville, Orlando, Miami, or Jacksonville must treat subcontractor verification as a daily operational rule, not a suggestion.
When Florida contractors work in other licensed states, the rules change. Workers' compensation requirements, exemption rules, and additional insured case law vary by state. A subcontractor's Florida policy may not automatically cover work in Georgia or Texas unless the policy is properly endorsed. General contractors managing multi-state projects must verify that the subcontractor's insurance applies to the state where the project is located.
In licensed states, the state licensing board may also have specific insurance requirements for trade contractors. However, a general contractor's requirements are often higher than the state minimums. State minimums are designed to protect the public; a general contractor's requirements are designed to protect the general contractor and the project owner. Do not rely on a state license as proof of adequate insurance.
When to Review Your Policy
Review your subcontractor insurance requirements before you draft your standard subcontract agreement. The insurance section of the contract should be reviewed by legal counsel and discussed with your insurance agent to ensure the requirements are clear, current, and commercially reasonable for the trades you hire.
You should also review your own contractor insurance at renewal to understand how your carrier views subcontractors. Some carriers require general contractors to collect certificates from 100% of subcontractors, and failure to do so can result in higher premiums or non-renewal. Some policies also include a "subcontractor warranty" endorsement that limits or excludes coverage if the general contractor fails to collect the required certificates.
Review your tracking system regularly. Whether you use a spreadsheet, a software program, or an administrative assistant, you need a reliable way to know when a subcontractor's policy is expiring and when a new certificate is needed. A certificate is only good for the dates listed on it.

FAQs
Why do general contractors need certificates from subcontractors?
Certificates provide evidence that the subcontractor has their own insurance. If a subcontractor causes a claim and has no insurance, the general contractor's policy will likely have to respond, which can increase the general contractor's premiums or lead to non-renewal.
What happens if a subcontractor does not have workers' compensation in Florida?
Florida DFS states that if a subcontractor lacks required workers' compensation, the subcontractor's workers become the employees of the contractor for workers' compensation benefit purposes after a work-related injury.[1]
Is being a certificate holder the same as being an additional insured?
No. A certificate holder simply receives notice of the policy. Additional insured status gives the general contractor specific coverage rights under the subcontractor's policy for claims arising out of the subcontractor's work.
Can a subcontractor use a workers' compensation exemption?
In Florida, eligible corporate officers or LLC members can file for an exemption, but it only applies to them personally. If they bring employees or helpers to the jobsite, those workers must be covered by a workers' compensation policy.
How often should I request a new certificate?
You should request a new certificate before the subcontractor's current policy expires. If a project lasts longer than the policy term, you need a renewal certificate to prove continuous coverage.
