This bill introduces new requirements for insurers in Washington State regarding the use of wildfire risk models and the disclosure of wildfire risk scores to property insurance applicants and policyholders. A new section is added to chapter 48.18 RCW, mandating that insurers provide detailed information about the wildfire risk score of a property, including the score itself, 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 and in plain language within specified timeframes after a coverage decision or policy renewal, nonrenewal, or cancellation. Additionally, policyholders have the right to appeal inaccurate wildfire risk scores, and insurers are required to respond to these appeals within set time limits.

Another new section is added to chapter 48.19 RCW, which requires insurers to disclose the wildfire risk models and scoring methods used in their rate filings to the state commissioner. Insurers must ensure that property-specific and community-level mitigation actions are incorporated into their models or provide actuarially sound discounts for policyholders who demonstrate such actions. Furthermore, insurers are required to make information about available premium discounts and the appeal process for wildfire risk scores accessible on their public websites. The bill emphasizes the importance of transparency and accountability in the use of wildfire risk assessments in property insurance underwriting and rating.
