Energy Efficiency for Affordable Housing Act

This bill increases tax credits for affordable housing developers who improve energy efficiency in existing buildings. It adds a 30% credit boost (to 130% of rehabilitation costs) for buildings meeting specific energy standards, either by adopting a government-determined advanced construction standard or using a certified retrofit plan that reduces energy use by 50% or more. Buildings in high-cost areas qualify for an additional 30% boost (to 160% of costs) if they meet these standards. The changes apply to housing credit allocations after December 31, 2025, with specific rules for bond-financed projects.
