Nine zip codes out of more than 1,700 in the state account for about 7% of the FAIR Plan's liability exposure, or $44 billion as of September 2025, according to a Bloomberg News analysis of the
Well-off communities as determined by median income and home values comprise five of the top 10 highest liability zip codes. A sixth is the mountain resort community of Lake Arrowhead, where about
California is one of 34 US states that offer last-resort insurance plans. The Golden State stands out, though, for the magnitude of residential liability and the frequency and intensity of wildfires that increasingly push into urban areas. This month, the state's largest utility,
"As more risk accumulates in a small number of communities, a single disaster can generate significant losses and increase the likelihood of assessments that ultimately affect the broader insurance market," Karen Collins, vice president for property and environmental at the industry advocacy group American Property Casualty Insurance Association, said in an email.

That means they're effectively subsidizing wildfire losses for high-value homes. "It is a real challenge in terms of how to undo this escalation of liability that we're seeing," said Nancy Wallace, the paper's author and a professor of finance and real estate at UC Berkeley's Haas School of Business.

In the six months up to March, policies grew 6.1% while exposure risk rose 8.3%, according to FAIR data.

Michael Soller, a spokesperson for the California Department of Insurance, said that overall FAIR Plan growth has slowed recently in response to
"We are seeing initial signs of market stabilization and recovery," he said in an email.

That's still too much, according to Michael Wara, director of the climate and energy policy program at Stanford University, noting the cap is four times the median California home value.
Wara said one way to limit FAIR's exposure risk is to exclude second homes from the plan and force those homeowners to seek coverage from
