A widely circulated post on X this week captured a decision that is becoming less unusual in California's high-fire geographies. The author described a friend whose paid-off mountain home was forced onto the FAIR Plan — the state's insurer of last resort — and who, after weighing the cost against the coverage, chose not to insure the property at all. The reasoning was blunt: the FAIR Plan is expensive, it may not make a homeowner whole after a loss, and if everything around the house burns, the owner would not want to rebuild there anyway.

It is an anecdote, not a dataset. But it names a pressure point that statewide numbers now confirm.

The residual market under strain

The FAIR Plan was designed as a temporary backstop, not a destination. Yet as admitted carriers have retreated from fire-exposed zones, it has absorbed a concentrated and growing book of the riskiest inventory in the state. In 2024 alone, California saw more than 200,000 home insurance non-renewals and cancellations statewide, with State Farm accounting for roughly 72,000 of those policies — a migration that funnels homeowners toward the residual market by default.

29% — residential rate increase approved for the California FAIR Plan, effective in 2026 (SF Chronicle).

200,000+ — non-renewals and cancellations across California in 2024 (broker filings via X).

The cost side is moving fast. California regulators approved a roughly 29% residential rate increase for the FAIR Plan, taking effect in 2026. For a homeowner already paying a premium that feels punitive, a near-30% jump tests the logic of staying covered at all — particularly when the FAIR Plan's basic coverage and questions about its capitalization leave owners uncertain they would be made whole after a total loss. The post's author was not alone in asking whether the program is solvent; that question has been raised by analysts watching the plan's exposure concentrate.

What going bare means for the market

When a homeowner with a paid-off property elects to carry no coverage, the decision is rational at the individual level and corrosive at the market level. It removes a premium-paying participant from the pool, signals that the price of risk has outrun the value of protection, and — for properties that still carry a mortgage — is simply not available. In Los Angeles County's fire-exposed luxury corridors, where replacement costs run into eight figures, going uninsured is rarely an option a lender will permit.

That leaves the more telling variable hiding in plain sight: the building. The FAIR Plan, like every admitted carrier, prices a structure on how it is likely to behave when embers arrive. A combustible envelope on a ridgeline reads, to an underwriter, as a probable claim. The homeowner in this story did the only math available to her given the house she had. The more consequential math happens earlier — at the wall, the roofline, and the first five feet of ground — where what gets built decides which insurance conversations are even possible.

California's Safer from Wildfires framework, which recognizes mitigation across three layers — structure, parcel, and community — exists precisely because carriers want a way to distinguish a hardened building from a vulnerable one. The residual market's strain does not erase that distinction; it sharpens it.

The decision to go uninsured is rational at the individual level and corrosive at the market level — and it starts with the building.

As the FAIR Plan's costs climb and its role expands beyond what it was built for, the homeowners who keep a real choice will be the ones whose buildings give an underwriter something to price. The structures that read as near-certain losses will keep pushing their owners toward the same arithmetic the mountain-house owner ran — and toward the same answer.

Our Perspective
We keep coming back to the moment a homeowner does the math and concludes that paying for coverage is no longer rational. That calculation is not really about the FAIR Plan; it is about a building that the residual market reads as a near-certain claim. A non-combustible envelope changes the inputs to that math. Reinforced concrete — the system DGU has executed on buildings like the Kimbell Art Museum — does not promise a cheaper premium so much as it gives an insurer a structure worth pricing in the first place. When the wall is the fire barrier, the question shifts from whether to insure to who wants to. That is a quieter advantage than a discount, and a more durable one.
