Applying Nevada law, the Federal District Court in Florida found that the general contractor was entitled to a defense of claims based upon alleged faulty workmanship of a subcontractor. KB Home Jacksonville LLC v. Liberty Mutual Fire Ins. Co, 2019 U.S. Dist. LEXIS 151235 (M.D. Fla. Sept 5, 2019).

KB Home completed six residential developments utilizing various subcontractors. One subcontractor was Florida State Plastering, LLC (FSP) for installing stucco. Eighty-eight complaints against KB Home implicated FSP's stucco work. Plaintiffs alleged that the stucco subcontractor's work suffered from construction defects, causing damages not only to the exterior stucco, but also the underling wire lath, paper backing, house wrap, wood sheathing, interior walls, interior floors and other property.

Ironshore insured FSP under a CGL policy. KB Home was an additional insured for liability for property damage caused by "your work." KB Home was also insured under its own CGL policy with Liberty Mutual. Both insurers refused to defend.
