Wilseyville and the insurance market
Wilseyville sits in California, one of two states that legally require a wildfire-risk disclosure at sale. California's FAIR Plan, the state's insurer of last resort, ended 2025 with 668,609 residential policies after adding 21,859 in Q4 alone — the kind of market shift a 100th-percentile score like Wilseyville's can end up mattering for.
