• Homeowners are increasingly being dropped by their private home insurers.
• Regions with the highest nonrenewal rates are most prone to wildfires, hurricanes, and other disasters.
• A new Senate report warns of economic risks as climate change destabilizes insurance markets.

Homeowners across the country are increasingly facing a stark new reality: they're losing their home insurance.

The share of home insurance policies from large insurers that weren't renewed increased last year in 46 states, a report released Wednesday by the Senate Budget Committee found. The increasing frequency and intensity of disasters like wildfires, hurricanes, and flooding and the rising cost of rebuilding have pushed many insurers to drop customers or hike premiums. This has left thousands of homeowners scrambling to find new insurance policies or joining the growing ranks of those going without insurance.

More than 200 counties saw their non-renewal rates spike threefold between 2018 and 2023. Counties in Northern California and South Florida saw among the highest rates of nonrenewals. Coastal counties in Massachusetts, Mississippi, and North Carolina also saw dropped policies soar. Manhattan ranks 20th, with rates of dropped policies rising from 1.25% in 2018 to 4.11% in 2023.

The national scale of home insurance nonrenewals was previously unknown because insurance companies are regulated at the state level. The National Association of Insurance Commissioners said not all states collect granular data about the availability and affordability of coverage in some areas. The association in March announced an effort with state insurance regulators to try to fill the gap.

Senate Budget Committee Chairman Sheldon Whitehouse launched his own investigation into the homeowners' insurance market last year. He received nonrenewal data from 23 companies accounting for about two-thirds of the market. In testimony on Wednesday, Whitehouse said he demanded nonrenewal data because experts suggested policies being dropped were an early warning sign of market destabilization. He also said they correlated with higher premiums.

The American Property Casualty Insurance Association, a lobbying group representing insurance companies, said nonrenewal data doesn't provide "relevant information" on climate risks. Many factors, including a state's litigation and regulatory environment, factor into nonrenewal decisions, the association said.

The association added that more costly weather disasters, combined with inflation and overbuilding in climate-risk regions, are making insurance less affordable for many Americans.

Home insurance premiums are rising in many regions across the country. The National Bureau of Economic Research recently reported that average home insurance premiums spiked by 13%, adjusted for inflation, between 2020 and 2023.

Most mortgage lenders require homeowners to purchase insurance, and some require additional insurance for specific disasters, including flooding. Insurers refusing to offer coverage can hurt home values because homes that can't be insured in the private market are less desirable to potential buyers.

The Senate Budget report warned that the insurance crisis will get worse as the climate crisis fuels more frequent and destructive disasters, including hurricanes, wildfires, and flooding. A destabilized insurance market could "trigger cascading economy-wide financial upheaval," the report said.

"The failure to deal with climate change isn't just driving up the cost of homeowners' insurance, it's making it harder for families to even find homeowners' insurance, and that makes it harder to get a mortgage," Whitehouse said in a statement to Business Insider. "When the pool of buyers is limited to only those who can pay cash, it cuts off pathways to homeownership—particularly for first-time homebuyers—and risks cascading into a crash in property values that trashes the entire economy."
