New research led by the 91��ý’ (91��ý) Catastrophe Risk Management Center of Excellence (COE) demonstrates how science-based mitigation and catastrophe modeling can significantly reduce disaster losses and support stronger, more stable insurance markets. 

The analysis, conducted in partnership with the , found that rebuilding wildfire-impacted communities to the Insurance Institute for Business & Home Safety (IBHS) Wildfire Prepared Home™ Standards could reduce projected wildfire average annual losses (AAL) by up to 35 percent when adopted by all individual homeowners in the community. AAL is a central data point in insurance rates filings and can be a factor in determining whether insurers will offer coverage in an area and at what price. 

While focused on Los Angeles, the study illustrates the broader national value of the COE’s work in helping state insurance regulators assess risk and improve long-term insurability. 

“Catastrophe risk is a national challenge, and state insurance regulators rely on sound data and modeling to protect consumers and support healthy insurance markets,” said 91��ý President and Virginia Insurance Commissioner Scott A. White. “The Catastrophe Risk Management Center of Excellence helps regulators turn complex risk information into actionable insight.” 

Housed within the 91��ý’s Center for Insurance Policy and Research, the COE provides regulators with technical expertise on catastrophe models, training on risk analysis, and applied research to evaluate how mitigation strategies affect insurance pricing, underwriting, and availability. 

The California study highlights the importance of science-backed individual homeowner mitigation at scale. The research also found that rebuilding to the highest IBHS standard adds approximately three percent in costs to the project, an investment that can yield substantial insurance and safety benefits.  

While centered on wildfire risk, the findings underscore a national framework that can be applied across catastrophe-exposed regions. Through the COE, state insurance regulators share tools, research, and lessons learned to strengthen resilience, guide mitigation-funding decisions, and support faster, stronger recoveries after disasters.
