Weatherization Resilience and Adaptation Program Act

This bill creates a federal grant program to help low-income homeowners and affordable housing owners make their properties more resilient to climate-driven hazards like floods, wildfires, and extreme heat. It directs the Secretary of the Interior to award grants to states, tribes, and Native Hawaiian organizations to fund weatherproofing upgrades - including natural solutions like rain gardens - and requires strict eligibility rules (e.g., income ≤300% of poverty level, or properties with long-term affordability restrictions). Grantees must use funds for climate adaptation projects, provide outreach, and prohibit rent hikes for two years on multifamily buildings receiving funding. The program authorizes $250 million annually for 2024-2029 to implement these concrete resilience improvements.
