When your insurance company decides not to renew your policy, it's called a nonrenewal. And in some American ZIP codes, it's happening at epidemic rates.
Using Treasury FIO data covering 246 million policies from 2018-2022, we identified the ZIP codes where homeowners are most likely to lose their insurance coverage involuntarily.
The Top 10 ZIP Codes by Nonrenewal Rate (2022):
The data reveals a clear geographic pattern. Eight of the ten worst ZIP codes are in Florida, with Louisiana and coastal Mississippi filling the remaining spots. Miami-Dade County alone has multiple ZIP codes with nonrenewal rates exceeding 12% — meaning more than 1 in 8 homeowners received a nonrenewal notice in a single year.
33139 (Miami Beach, FL) tops the list with a nonrenewal rate of 14.8%. This barrier island community faces extreme hurricane exposure, and multiple insurers have exited entirely.
70112 (New Orleans, LA) ranks second at 13.2%. The post-Hurricane Ida insurance exodus has left New Orleans with a fraction of its pre-2021 carrier options.
34102 (Naples, FL) at 12.4% reflects the Southwest Florida coast's vulnerability after Hurricane Ian in 2022, which caused $110 billion in damage.
What does this mean? Nonrenewals are a leading indicator of insurance market failure. When nonrenewal rates exceed 10%, the private market is effectively collapsing in that area, pushing homeowners toward FAIR Plans and last-resort coverage.
