The bill introduces new requirements for insurers in Washington State regarding the use of wildfire risk scores in property insurance. It mandates that insurers provide detailed information about the wildfire risk score to applicants and insured individuals, including the current score, the range of possible scores, the creator of the score, the date it was generated, and key factors affecting the score. Insurers must deliver this information in writing within specified timeframes following coverage decisions and must also allow policyholders to appeal inaccurate scores. Additionally, insurers are required to provide a revised score within 30 days if the policyholder has completed mitigation actions to reduce wildfire risk.

Furthermore, the bill establishes guidelines for insurers using wildfire risk models or catastrophe models in their underwriting and rating processes. Insurers must submit detailed descriptions of these models, including their impact on rates and actuarial justifications, to the commissioner as part of their rate filings. The bill emphasizes the importance of incorporating property-specific and community-level mitigation actions into these models and requires insurers to offer discounts for policyholders who demonstrate such actions. Insurers are also obligated to make information about available discounts and the appeal process accessible on their public websites.
