The 13 riskiest U.S. metros for commercial real estate in 2026

Underwriting a commercial deal on cap rate and comps while treating insurance as a fixed line item is how 2026's pro formas are blowing up. Property insurance has gone from a rounding error to the swing variable in the model — and it is not random. It tracks natural-hazard exposure, which the federal government already scores, county by county.

We pulled the FEMA National Risk Index for the principal county of 89 major U.S. metros and ranked them by composite risk. Thirteen rate “Very High” — the top national tier. The full, sortable list lives on the PropHunt Risk Index; below is what stood out, and what it means for how you underwrite a market.

Scores are 0–100 national percentiles against every U.S. county. “Expected annual loss” (EAL) is FEMA's modeled average-year loss from natural hazards for the county.

Both score a perfect 100. LA's risk is the famous wildfire-and-earthquake combination. Chicago's is tornado (a perfect 100) plus riverine flooding (99.9) — hazards that rarely make it into an out-of-state buyer's model and squarely into their insurance premium. If your mental map of “risky markets” is just the coasts and California, you are mispricing the Midwest.

Seattle ranks 99.7 almost entirely on seismic exposure (earthquake 99.9). A Cascadia subduction-zone event does not show up in a five-year hold projection — it shows up in carrier pricing and availability today. We dug into why the West Coast ranks so high, and why the risk is structurally underpriced, in our piece on earthquake risk.

Los Angeles County's expected natural-hazard loss runs roughly $7.6 billion per year, about $5.9 billion of it on buildings— the exact slice carriers underwrite, and the reason California non-renewals keep accelerating. This is not an abstraction: academic work published in Nature Climate Change estimates U.S. residential property is overvalued by $121–$237 billion precisely because flood risk is underpriced in today's sale prices.

Composite scores are useful for ranking, but you underwrite against specific perils. The pattern is consistent: the highest-percentile peril in a market is where carriers tighten first.

• Wildfire — Riverside, San Diego, and Los Angeles sit at the top percentile. This is where carriers are non-renewing and FAIR-Plan pricing takes over. Full breakdown in our California wildfire deep-dive.
• Hurricane & coastal flood — Houston, Miami, and Fort Myers. Premiums and deductibles here can move a deal's NOI by double digits. See flood risk and the NFIP.
• Tornado / severe convective storm — Chicago, Houston, San Antonio. Wind/hail deductibles and roof age are what underwriters price.

The full mechanism — how hazard scores translate into premiums, deductibles, and outright non-renewal — is the subject of why property insurance is breaking CRE deals, including how to underwrite it before you are under contract.
