The endorsement that turns a contract requirement into actual coverage — and the forms that quietly limit it.
Commercial · Updated September 2026
When a general contractor hires your crew, or a landlord leases you a space, they face a real risk: something your business does could produce a claim against them. Requiring additional insured status puts them under your policy for claims arising out of your work, so your insurer defends and pays rather than theirs.
It is not a courtesy. It is a transfer of risk, and it is why almost every commercial contract of any size includes it.
Additional insured endorsements come in different forms and the differences are substantial. Some cover the other party only for claims arising from your ongoing operations — that is, while the work is being performed. Others extend to completed operations, covering claims that surface after the job is finished.
For construction, completed operations is often the more important half, because defects and injuries frequently appear months or years after the last invoice. A contract that requires completed operations coverage is not satisfied by an ongoing operations endorsement, even though both are called additional insured.
Contracts commonly require your policy to respond first, without seeking contribution from the other party's insurance. That language has to be reflected in an endorsement; agreeing to it in a contract does not by itself change how the policies share a loss.
Waiver of subrogation is the related request: your insurer gives up its right to recover from the other party after paying a claim. Both of these usually require specific endorsements and may affect premium.
A scheduled endorsement names each additional insured individually. A blanket endorsement automatically extends status to anyone you have agreed in a written contract to add. Blanket wording is far easier to administer when you work for many clients, but the trigger is a written contract signed before the loss — a handshake agreement will not activate it.
Read the insurance section of the contract and confirm three things: whether additional insured status must include completed operations, whether primary and non-contributory wording is required, and what limits are demanded. Then send it to your agent before signing. Agreeing to requirements your policy cannot meet creates a contractual breach you will only discover during a claim.
