Who Typically Requests Additional Insured Status

The most common example is a general contractor requiring a subcontractor to add them as an additional insured on the subcontractor's general liability policy, so that if the subcontractor's work causes a third-party injury or property damage, the general contractor is also protected under that policy. Landlords often require the same from commercial tenants, and businesses hiring vendors or independent contractors do the same for their own protection.

Blanket vs. Scheduled Additional Insured Status

A scheduled additional insured endorsement names one specific party. A blanket additional insured endorsement automatically extends coverage to anyone the policyholder is contractually required to add, without needing a new endorsement every time a new contract is signed. Contractors who work with many different general contractors usually prefer blanket endorsements because they eliminate the paperwork lag of adding parties one contract at a time.

Why This Matters

Being added as an additional insured only protects the additional insured for liability arising from the named insured's work, it does not give them their own full policy, and it doesn't cover claims against the additional insured for their own separate negligence. Businesses that skip verifying this status, or that assume a certificate of insurance alone proves the endorsement exists, can find out only after a claim that they were never actually added to the policy.
