As multiple devastating wildfires raged across California, a private firefighting crew reportedly helped save Kanye West and Kim Kardashian’s home in Calabasas, TMZ reported this week. The successful defense of the $50 million mansion is the most prominent example of a trend that’s begun to receive national attention: for-hire firefighters protecting homes, usually on the payroll of an insurance company with a lot at risk. The insurance companies AIG and Chubb have publicly talked about their private wildfire teams. AIG has its own “Wildfire Protection Unit,” while Chubb—and up to a dozen other insurers—contract with Wildfire Defense Systems, a Montana company that claims to have made 550 “wildfire responses on behalf of insurers,” including 255 in just the past two years.
