JB Pritzker signed two bills Tuesday aimed at protecting Illinois homeowners and drivers from unfair home and auto insurance rate hikes. House Bill 4273 focuses on homeowners insurance. The measure would require insurers to provide 60 days' notice before raising rates by more than 10%, giving policyholders time to compare coverage options. It would also prohibit "cost shifting," preventing insurance companies from passing losses from natural disasters in other states, such as California wildfires or Florida hurricanes, on to Illinois homeowners. Under the bill, homeowners insurance rates must be based solely on Illinois claims data.
