The two biggest disaster states run the same kind of backup insurer.
Right now, those backups are heading in opposite directions.
One is swelling. The other is emptying out.
When private insurers will not cover a home, the state steps in. This backup is called the insurer of last resort.
California calls its version the FAIR Plan. Florida calls its Citizens.
California's FAIR Plan is bursting. Its exposure is the total it could owe if disaster strikes.
That figure reached about $603 billion by June 2025, state data shows. It is up 424% since September 2020.
More homes keep landing on the plan as private carriers pull back. Florida went the other way.
Its Citizens shrank from a peak of 1.42 million policies in 2023. By the end of 2025, it held about 385,000, its lowest ever.

Florida changed its rules. New laws cut down on lawsuits and tightened oversight.
That pulled 17 new insurers into the state. It also drew homeowners back into the private market.
Florida moved more than 546,000 policies off Citizens in 2025, the company said. It is now planning its first rate cut since 2015.
California's plan, meanwhile, is still absorbing homes that carriers dropped. The two cases split because the rules did.
Policy drove the change, not the weather. That is the real lesson here.
Here is the danger in a bloated backup plan. A huge disaster could drain it fast.
If that happens, the FAIR Plan can charge private insurers to cover the gap. Those costs do not vanish.
They can land on every customer in the state. Even people who never used the plan would pay.
The state still has about 8.3 million home policies. The backup plan held about 668,000 in December.
Florida built its own backup in 2002. It was meant only for owners shut out of the market.
Today it is no longer the largest insurer there. That is a sign the private market came back.
Its average cut is about 2.6%. Three in five customers will save about $359.
That is real relief for Florida owners. The other state's owners are still waiting for theirs.
The split is striking. Same kind of plan, two very different paths.
One state fixed its rules and shrank the backup. The other is still soaking up dropped homes.
The lesson is simple. Rules, not weather, decide which way the plan goes.
The ripples reach the wider housing market too. Dropped policies can stall home sales.
Fewer buyers can soften prices. So the backup plan is a housing story too.
Watch the exposure numbers. They are the clearest sign of a market healing or breaking.
