In Stoneledge at Lake Keowee Owners Ass'n v. Cincinnati Ins. Co., 2022 U.S. App. LEXIS 34292 (D.S.C. Dec. 13, 2022), the Fourth Circuit Court of Appeals addressed the adequacy of reservation of rights letters issued by Builders Mutual Insurance Company (“Builders Mutual”) and Cincinnati Insurance Company (“Cincinnati”) to their insureds, Marick Home Builders, LLC (“Marick”) and Rick Thoennes (“Thoennes”), Marick’s managing member, for an underlying construction defect lawsuit. In short, the Fourth Circuit found that the reservation letters were inadequate to preserve the insurers’ coverage defenses because they did not sufficiently explain the basis of the carriers’ position. 

Stoneledge, a homeowners association, managed a community of 80 townhomes on South Carolina’s Lake Keowee. In 2009, Stoneledge brought suit against Marick and Thoennes, among other defendants, alleging construction defects in the townhomes that resulted in water intrusion and other physical damage. Marick and Thoennes held commercial general-liability policies through Cincinnati and Builders Mutual covering, in relevant part, “property damage” as defined by the policies. Builders Mutual issued policies covering the period from January 2004 to October 2007, and Cincinnati issued policies covering the period from April 2008 to April 2012. After Marick notified the insurers of the underlying action, Builders Mutual sent Marick two reservation of rights letters, one in May 2009 and one in July 2009. Cincinnati sent Marick one reservation of rights letter in March 2010.

In March 2014, Stoneledge brought a declaratory-judgment action against Cincinnati seeking coverage for a judgment entered in the underlying action. The insurers removed the case to federal court, and in September 2016, Stoneledge amended its complaint, adding Builders Mutual as a defendant and seeking coverage for additional damages pursuant to a settlement agreement entered into by Stoneledge, Marick, Thoennes. The district court granted Stoneledge's motion for  summary judgment, primarily on the ground that the insurers failed to reserve the right to contest coverage. The insurers appealed to the Fourth Circuit, which affirmed.
