CG 20 26
Additional Insured — Designated Person or Organization
Additional Insured — Designated Person Or Organization (ISO General Liability)
Broadest-grant scheduled Additional Insured form — coverage for the AI's liability arising out of the named insured's operations, without the ongoing-operations limitation.
What it does
CG 20 26 grants AI status to a person or organization scheduled on the endorsement for liability caused, in whole or in part, by the named insured's acts or omissions or those of someone acting on the named insured's behalf in the performance of the named insured's ongoing operations. It is broader than CG 20 10 because it is not tied to a specific 'owners, lessees, or contractors' relationship; any party the named insured wants to schedule can be added. Many lease and service agreements specifically request CG 20 26 because its grant language is broader than CG 20 11.
When you need it
- Service agreements where the customer is neither a lessor nor a contractor but still expects AI status.
- Property managers who want AI status across both common-area and tenant-space exposures.
- Vendors whose customer's risk-management standard specifies CG 20 26 by name.
Common mistakes
- Using CG 20 26 on a construction project where CG 20 10 + CG 20 37 are the correct paired forms.
- Accepting CG 20 26 with no completed-operations coverage on long-tail service work — pair with CG 20 39 if needed.
- Forgetting that the form is scheduled — the AI must appear on the endorsement schedule or via a contract-reference clause.
