Wildfire risk and California real estate: the FAIR Plan, non-renewals, and what underwriters miss

California real estate has a wildfire problem that is really an insurance problem. The fires get the headlines; the non-renewal letter gets the deal. If you are buying commercial or multifamily anywhere from Riverside to San Diego to the Los Angeles wildland-urban interface, the wildfire score on the Risk Indexis a leading indicator of your insurance cost — and increasingly, of whether you can get covered at all.

On FEMA's National Risk Index, the top-percentile wildfire metros are Riverside (100), San Diego (100), and Los Angeles(99.9), with Sacramento and the Inland Empire close behind. These are not remote forest parcels — they are dense, high-value metros where the wildland-urban interface runs straight through investable submarkets.

California regulators, for years, did not allow insurers to price forward-looking catastrophe models into rates. Combined with severe loss years, that pushed private carriers to do the only thing they could: stop writing in high-risk areas. California Department of Insurance data shows a roughly 19% drop in policies in the highest-risk wildfire areas between 2015 and 2023, much of it from non-renewals. The RAND / California Fourth Climate Change Assessment report documents the same retreat and its link to the regulatory rate-making regime.

When the admitted market exits, owners fall back to the California FAIR Plan— the insurer of last resort — whose exposure grew from about $50 billion in 2018 to roughly $458 billion in 2024. FAIR Plan coverage is typically narrower and often priced at 2–3× admitted rates, usually requiring a separate difference-in-conditions policy to fill the gaps. That spread is the real cost of a high wildfire score.

• Current carrier and renewal date. Is the in-place policy admitted or already FAIR Plan? When does it renew, and has the carrier signaled non-renewal?
• A bound quote in your name.Carriers now ask about proximity to wildland, defensible space, roof and vent construction, and prior evacuation history — granular underwriting that a verbal estimate ignores.
• Mitigation credits.California's “Safer from Wildfires” framework requires carriers to recognize hardening (Class-A roof, ember-resistant vents, defensible space). These can materially move the premium — price the post-mitigation number.
• The FAIR Plan + DIC stack. If admitted coverage is unavailable, model the all-in cost of FAIR Plan plus the difference-in-conditions wrap, including the wider deductibles.

Wildfire is one peril; the same discipline applies to flood and earthquake, and the broader pattern is covered in why property insurance is breaking CRE deals. For a market-by-market view, start with the riskiest-metros ranking.
