The Green and Resilient Retrofit Program (GRRP)

On August 16, 2022, the Inflation Reduction Act (IRA) was signed into Law. Section 30002 of Title III of the IRA, (Publ. L. 117-169), titled “Improving Energy Efficiency or Water Efficiency or Climate Resilience of Affordable Housing”, provides funding for direct loans and grants to fund projects that improve energy or water efficiency, enhance indoor air quality or sustainability, implement the use of zero-emission electricity generation, low-emission building materials or processes, energy storage, or building  electrification strategies, or address climate resilience, of eligible HUD-assisted multifamily properties. 

There is also funding available under this provision for HUD’s benchmarking initiative that will finance Energy and Water benchmarking of HUD-assisted properties to measure usage and efficiency of those properties. Owners do not have to receive a grant or loan under GRRP to participate in HUD’s Benchmarking Initiative. Eligible owners primarily include owners receiving HUD rental assistance under Multifamily Section 8 Project-Based Rental Assistance (PBRA), Section 202 Supportive Housing for Low-Income Elderly, and Section 811 Supportive Housing for Low-Income Persons with Disabilities. Public housing and properties with vouchers are not eligible.

Stakeholders can find the Inflation Reduction Act of 2022, published on Congress.gov, here
