The federal district court found that the additional insureds had to meet the policy’s self-insured retention before a duty to defend was triggered. Amerisure Ins. Co. v. Premier Design & Build Group, LLC, 2026 U.S. Dist. LEXXIS 170741 (N.D. Ill. July 31, 2026).

Amerisure issued CGL and umbrella policies to Premier Design & Build Group, LLC. Amerisure had the right and duty to defend in certain suits for property damage under both policies.

Premier contracted with MG East, LLC (MGE) to build three buildings. After the buildings were constructed, MG filed suit against Premier in state court, seeking recovery for allegedly defective installation of the roof, flashing, and gutters on each of the buildings. Premier had subcontracted with Tecta American Sough Florida, Inc. to install the flashing.
