This bill introduces new requirements for insurers in Washington State regarding the use of wildfire risk scores in property insurance. It mandates that insurers provide policyholders with detailed information about their wildfire risk score when nonrenewing or canceling a policy due to wildfire risk, or when premiums are adversely affected by the score. This information must include the current wildfire risk score, the range of possible scores, the entity that created the score, the date it was created, and key factors contributing to the score. Insurers are also required to offer a revised wildfire risk score upon request if the policyholder has taken mitigation actions to reduce risk.

Additionally, the bill requires insurers to disclose the wildfire risk models and scoring methods used in their rate filings to the state commissioner, ensuring that these models account for both property-specific and community-level mitigation efforts. Insurers must also provide accessible information on their websites regarding potential discounts or incentives for policyholders who undertake mitigation actions. The bill emphasizes transparency and accountability in how wildfire risk is assessed and communicated to consumers, while also protecting sensitive model information as trade secrets.
