If you're a general contractor in Minnesota who hires subcontractors, the insurance practices of those subs are directly your problem. An uninsured or underinsured subcontractor working on your project is an exposure you carry — in some cases literally, if their workers' comp status is ambiguous and an employee gets hurt. Here's what you need to know and what to require.
Why Subcontractor Insurance Is Your Business
When a subcontractor works on your project, they bring workers, equipment, and liability exposure onto a site you're responsible for coordinating. If something goes wrong:
- A sub's worker falls from scaffolding → if the sub has no workers' comp, the claim may come back to you
- A sub damages the owner's property → if the sub has no GL, the property owner's claim comes to you (the GC) since you're responsible for the project
- A sub's vehicle causes an accident while hauling materials → if they have no commercial auto, the injured party may pursue you as the party that hired the sub
Your own GL policy may provide some protection in these scenarios through your additional insured status on the project, but your insurer will want to subrogate against the sub's carrier first — and if there's no carrier, you absorb the exposure. Worse, your GL rates and loss history get hit by claims that were really the sub's fault.
The Workers' Compensation Issue Is Especially Critical
Minnesota workers' compensation law creates a concept called "statutory employer" liability. In certain situations, if a subcontractor's employee is injured and the sub doesn't have workers' comp coverage, the GC (as statutory employer) can be held responsible for those benefits. This isn't theoretical — it's a documented risk for GCs who work with uninsured subs.
The independent contractor vs. employee distinction in Minnesota is determined by a multi-factor test, not just what you call the relationship. A sub who works exclusively for you, follows your direction on how to perform the work, and uses your tools may be considered a de facto employee for workers' comp purposes regardless of the contract language. If that person is injured and the sub has no workers' comp, you may be responsible.
Requiring a certificate of insurance showing workers' comp coverage from every subcontractor is not just a best practice — it's basic risk management that every GC should treat as non-negotiable before allowing a sub on a job site.
What to Require From Every Subcontractor
The minimum insurance requirements you should demand from subcontractors depend on the nature of the work and the project, but a reasonable baseline for most trades in Minnesota is:
General Liability: $1,000,000 per occurrence / $2,000,000 aggregate. The sub should name you (and the property owner if applicable) as additional insureds on their GL policy, including completed operations. This means if a defect in the sub's work creates a claim after the project is done, your name is on their policy as a covered party.
Workers' Compensation: Statutory limits as required by Minnesota law. If the sub has employees, they must have workers' comp. If they claim to be a sole proprietor with no employees, get written documentation of that claim — and understand that you're accepting risk if that turns out to be inaccurate.
Commercial Auto: $1,000,000 combined single limit for any vehicles used in connection with the project. Trucks and work vans driving to your job site create auto liability exposure while associated with your project.
Umbrella: For higher-risk trades (roofing, structural, excavation), requiring a $1M or $2M umbrella above the primary GL is reasonable and increasingly common on commercial projects.
How to Verify — Actually Verify — Coverage
Collecting certificates of insurance is step one. But a COI is a point-in-time document — it shows the sub had insurance when the certificate was issued, not necessarily right now. Coverage can lapse after a certificate is produced.
Practical steps for meaningful verification:
- Request certificates before each project begins, not once at onboarding. A sub who had coverage six months ago when you first worked with them may have let their policy lapse since then.
- Check expiration dates. A certificate showing a policy that expires in two weeks for a three-month project is not adequate. Require renewal certificates when policies expire during your project.
- Confirm the additional insured endorsement. A certificate listing you as the certificate holder is not the same as naming you as an additional insured. The COI should specifically state "Additional Insured per endorsement" and reference the endorsement form number.
- Keep a COI tracking log. For active projects with multiple subs, a simple spreadsheet tracking each sub's coverage, expiration dates, and limits ensures nothing slips through.
What Happens When You Don't Require It
Some GCs don't require certificates consistently because it adds friction to getting subs on a job quickly, or because they've worked with a sub for years and trust them. The risk calculus on this is asymmetric: the friction of collecting a certificate is minor; the exposure from an uninsured sub incident is potentially enormous.
Beyond the financial exposure, there's a licensing consideration. Minnesota DLI licensing rules for residential contractors include requirements around subcontractor practices. A claim arising from an uninsured sub can affect your license in addition to your finances.
If You're a Subcontractor Reading This
If you regularly work as a subcontractor to GCs, the insurance requirements they're imposing on you are real and they'll affect your ability to win work. A GL policy with the right additional insured endorsements, current workers' comp if you have employees, and a commercial auto policy for your work vehicles — issued by a broker who can produce certificates and endorsements quickly — is a competitive advantage, not just a compliance exercise.
