The Wildfire Insurance Affordability Act establishes two main programs to help homeowners protect their properties from wildfires and afford insurance in high-risk areas. The first program creates federal grants distributed to state insurance departments, local fire departments, and Indian tribes to fund home hardening and wildfire mitigation projects like upgrading roofs, clearing vegetation, and installing fire-resistant materials, with a maximum of ten thousand dollars per household. The second program is a five-year pilot that provides vouchers to help low-income households in elevated wildfire risk areas pay their insurance premiums, but only if they have already completed fire safety improvements. The bill also makes the grant money and voucher assistance tax-free for recipients. State agencies must report annually to Congress on whether the pilot program successfully reduces insurance costs and keeps private insurers in their markets.
