A recent Illinois Appellate Court’s decision in, Acuity Ins. Co. v. 950 West Huron Condominium Owners Association, 2019 IL App (1st) 180743 (2019), strengthens Illinois’ precedent favoring construction defects as an occurrence under a Commercial General Liability (“CGL”) insurance policy. Acuity also broadens an insurance carrier’s obligation to defend its insured against construction defect allegations.
In Acuity, the court determined whether claims for construction defect filed against a subcontractor, triggered a duty to defend under a CGL policy. To make its determination, the court focused on the subcontractor’s scope of work. The court notes that a subcontractor normally contracts for a discrete scope of work on a project. Unlike a general contractor, who has control over or contractual obligations for all aspects of the project, a subcontractor does not have those board responsibilities. The court explained that “[f]rom the eyes of the subcontractor, the ‘project’ is limited to the scope of its own work, and the precise nature of any damage that might occur to something outside of that scope is as unknown or unforeseeable as damage to something entirely outside of the construction project.”
Accordingly, the court in Acuity held that when a complaint alleges that a subcontractor’s negligence caused damage to a part of the construction project outside of the subcontractor’s scope of work, the allegations are enough to trigger the insurer’s duty to defend the subcontractor under a CGL policy. The court’s decision in Acuity relied on a similar Illinois Appellate Court decision, Milwaukee Mut. Ins. Co. v. J.P. Larsen, Inc., 956 N.E.2d 524 (Ill. App. 2011). In Larsen, the court reached a similar conclusion where a third-party complaint by a general contractor against a subcontractor alleged that the subcontractor’s improper window caulking caused water intrusion and property damage to other parts of the building. The court in Larsen held that because the complaint alleged not only construction defects, but also damage to other property outside the subcontractor’s scope of work, the insurer had a duty to defend the subcontractor.
