A 2019 lightning fire destroyed a sprawling Illinois mansion. Chubb paid $8.75 million for the house - and just $25,000 for everything inside.
On July 13, 2026, a federal appeals court upheld that split, and the reasoning should resonate with any underwriter or claims professional who has watched a coverage gap go unaddressed.
When lightning struck the 24,000-square-foot mansion in southern Illinois in October 2019, the fire wiped out the house and its contents. Chubb National Insurance Company paid the full $8.75 million limit for the structure. Then it paid just $25,000 toward a $3.5 million contents claim - and the US Court of Appeals for the Seventh Circuit agreed the insurer read the policy correctly.
Everything turned on how the owner used the place. He bought the estate decades ago as a family retreat, then built it into a commercial lodging and events business - a "luxury country inn and resort," in the estate's own words. His consulting firm paid a $70,000 monthly retainer to hold training sessions there. The estate hosted up to sixteen weddings a year. In 2017 and 2018, it earned $1 million in lodging revenue, and his tax returns claimed 365 rental days.
Yet he kept the mansion on a "Masterpiece" homeowner's policy rather than upgrading to commercial cover. That policy offered $3.5 million for contents but excluded "business property" - furnishings and equipment "used to conduct your business" - and capped any such loss at $25,000. Because guests freely used the art, antiques, and furniture filling the house, the court found nearly all of it counted as business property.
The timeline is the sharp lesson for insurers. In June 2017, more than two years before the fire, a Chubb underwriter flagged that the estate was no longer just a home, warned the owner's broker of a possible "large gap in coverage," and urged a commercial policy. The homeowner's policy was renewed anyway, in 2018 and 2019.
The court noted one limit on Chubb's position: items kept from guests, in a wine cellar, a gun safe, and two locked bedroom closets, were not business property, since guests never touched them.
The owner also alleged bad faith, pointing to his $48,000 annual premium and branding Chubb's investigation a "sham." The court rejected both arguments, calling the coverage dispute genuine and Chubb's reading correct. A real dispute over coverage, it said, is neither "vexatious" nor "unreasonable."
The takeaway, in the court's words: broad coverage grants "usually come with specific exclusions and limitations." Those limits turned a $3.5 million claim into a $25,000 payout.
