This fire like with recent hurricanes or other natural disasters will bring insurance questions that need to be solved.
Some states may not allow Insurance companies to accurately model the expected risks based on future projections, they can only look backwards. I believe this differs from state to state. If the companies see too much risk, then the state may have to jump in to provide insurance with a public-private insurance company. Then taxpayers may partially be on the hook for payouts.
Note, CA recently made some regulation changes that some see as insurance industry friendly to keep them from ending coverage.
All homeowners may also need to accept higher premiums or higher deductibles since damages are increases. Which in turn may impact housing pricing. Future owners may value a house purchase at a lower amount since their annual insurance premiums would be much higher.
The recent disaster damage increases, whether or not someone believes in climate change, can't be denied.
