America's home insurance problem is set to intensify

• Private home insurers are dropping a growing number of customers in most states, a Senate report found.
• That leaves homeowners at risk, turning to more expensive last-resort options or going uninsured.
• While Florida has managed to reverse the trend somewhat, the risk to homeowners is set to intensify.

As Americans flock to places in the US vulnerable to natural disasters, private home insurance companies are running the other way.

The problem has left a rising number of homeowners with just one option to cover property damage: insurers of last resort.

The scale of homeowners losing their plans became clearer on Wednesday after a Senate Budget Committee investigation found that private insurers' nonrenewals spiked threefold in more than 200 counties between 2018 and 2023.

"What our new data reveal is that the failure to deal with climate change is also affecting whether families can even get homeowners insurance, which threatens their ability to get a mortgage, which spells trouble for property values in climate-exposed communities across the country," Senate Budget Chairman Sheldon Whitehouse said in releasing the report.

A recent study by Harvard University's Joint Center for Housing Studies found that between 2018 and 2023, the number of properties enrolled in California and Florida's insurers of last resort more than doubled. A similar trend is playing out in Louisiana. While Florida has reduced participation this year, it still has the highest enrollment in the country.

The problem isn't isolated to the most predictable states. The Senate Budget Committee found that the rate of homeowners losing their private insurance also rose in Hawaii, North Carolina, and Massachusetts.

Policymakers and insurers are trying to stabilize the private market, by enacting new laws and overhauling regulations. However, with scientists predicting that climate-fueled disasters will become more frequent and severe for the foreseeable future, the risk to America's homeowners is mounting.

Growing insurance risk has some states looking for solutions

In nearly three dozen states, insurers of last resort, known as Fair Access to Insurance Requirements, or FAIR, are available to homeowners and businesses who struggle to find insurance on the private market.

The numbers are rising because private insurers are pulling back coverage and hiking premiums in areas at risk of wildfires, hurricanes, flooding, and other disasters often made worse by climate change.

While state-mandated FAIR plans are designed to be a backstop, insurance regulators and private insurance companies are alarmed by how many homeowners and businesses are enrolling, especially in California and Florida. The plans are often more expensive and provide less coverage. Plus, saddling one insurer with the riskiest policies increases the chances of one major disaster sinking the system and leaving taxpayers and insurance companies with the bill.

Florida and California are trying to reverse the trend, and Florida has seen some progress. The state's insurer of last resort, Citizens Property Insurance Corporation, said on December 4 that its policy count dropped below 1 million for the first time in two years.

Mark Friedlander, a spokesperson for the Insurance Information Institute, said the drop reflects a series of changes in recent years to stabilize the state's private insurance market after more than a dozen companies left the state or stopped writing new policies.

The Florida legislature passed laws to curb rampant litigation and claim fraud that drove up legal costs for private insurers. Friedlander said insurance lawsuits in the first three quarters of 2024 are down 56%, compared with the first three quarters of 2021 — the year before the new laws were enacted. Citizens also started a "depopulation" program that shifts customers to the private market. State regulators in October said they had approved at least nine new property companies to enter the market, and premiums weren't rising nearly as much as last year.

In California, many of the deadliest and most destructive wildfires have occurred within the last five years. As a result, some private insurers are hiking premiums and limiting coverage in risky areas, pushing more homeowners to the insurer of last resort. The Harvard study found that policies in the state's FAIR plan doubled between 2018 and 2023 to more than 300,000. As of September, the California Insurance Commission said policies totaled nearly 452,000.

The commission is working to overhaul regulations to slow the trend, including requiring private insurers to sell in risky areas. In exchange, it should be easier for companies to raise premiums that factor in reinsurance costs and the risks of future disasters. That should help stabilize rates, said Michael Sollen, a spokesman for the commission.

Sollen added that in the past, private insurers could seek approval for higher premiums but weren't required to offer coverage in wildfire-prone areas.

"In a year from now, what's happening with the FAIR plan will be a key measure for us," he said. "We expect to see those numbers start to stabilize and go down."

A mounting home insurance crisis

Still, a reduction in state-backed plans isn't necessarily a sign of progress, Steve Koller, a postdoctoral fellow in climate and housing and author of the Harvard report, told Business Insider.

A growing number of homeowners in places like Florida, Louisiana, and California are purchasing private insurance from nontraditional providers barely regulated by state governments. These so-called "non-admitted" insurers don't contribute to a state fund that guarantees homeowners will have their claims paid even if the insurance provider fails, leaving their customers without access to this backup coverage.

"Someone could be moving to a private insurer from Citizens, and that insurer might have higher insolvency risk," Koller said.

He added that more homeowners are opting out of insurance altogether. The number of US homeowners going without insurance has soared from 5% in 2019 to 12% in 2022, the Insurance Information Institute reported.

Plus, Americans are increasingly moving into parts of the country most vulnerable to extreme weather. Tens of thousands more people moved into the most flood—and fire-prone areas of the US last year rather than out of them, the real estate company Redfin reported earlier this year.

As insurers of last resort try to shift more risk to the private market, home insurance premiums are expected to keep rising. That's especially true in the areas hardest hit by climate-fueled disasters.

If private insurers exit hard-hit regions en masse in the future, Koller said states might need to become the predominant insurance provider in the same way the National Flood Insurance Program took over after the private market for flood insurance collapsed in the 1960s. Most flood insurance plans are still issued by the federal government.

"My guess is states are going to work very, very hard to avoid that and ensure the existence of a robust private market, but that's a parallel that I can't personally unthink about," he said.
