Subcontractor compliance
What a subcontractor's certificate does and does not protect you from, the three ways a sub creates exposure, and how to check rather than collect.
Hiring a subcontractor does not transfer the risk as cleanly as most contractors assume. If a sub causes damage, the claim can reach you because you hired and supervised them. If a sub is injured and carries no coverage, the claim can be treated as yours.
That is why general contractors require certificates from every sub and why the requirement exists on both sides of the relationship. It is not bureaucracy, it is the coverage itself.
A file full of certificates proves nothing if none of them were read. The four things worth confirming on every one:
Potentially yes, in two ways. If their work causes damage the claim can reach you because you hired them. If they are injured without workers compensation, the claim can be treated as your employee's and land on your policy and your experience modification rate.
No. A certificate is evidence that their policy exists and gives you no rights under it. To be protected you need to be named as additional insured on their policy, which is a separate request.
The label does not decide it. If they take direction on hours and methods and provide no tools of their own, a workers compensation board can treat them as an employee after an injury, whatever the contract says. Either require coverage or confirm the classification properly.
Generally yes, or at least the limits your own contract requires. If a sub carries less than you are required to carry, the gap between their limit and your requirement is exposure you are holding.
