The purpose of the Wildfire Homeowner Relief Act is to explore the possibility of a federal buyout program for homeowners whose properties are located in areas at high risk of catastrophic wildfires. The act aims to provide a structured approach to help these homeowners by potentially purchasing their properties before or after a wildfire disaster occurs. Key provisions of the act require the Comptroller General of the United States to conduct a study on the feasibility of using federal grants to buy properties from willing homeowners in high-risk wildfire areas.
