This legislation creates financial incentives and safeguards to expand affordable housing construction. Section 3 increases tax credits available to builders who construct low-income housing with favorable features, such as projects paying workers prevailing wages, using renewable energy, locating near public transit, serving people with disabilities, or housing the poorest families earning under 30 percent of area median income, with bonuses up to 50 percent higher credits. Each state must dedicate at least one-third of its annual housing tax credits to projects meeting these criteria. Section 6 closes a loophole by eliminating the option for most affordable housing building owners to exit their affordable housing commitments early, requiring properties to maintain affordability restrictions throughout their required period, though buildings that received tax credits before January 1, 2027 retain existing exit options. Together, these provisions aim to encourage construction of affordable housing with quality standards while ensuring long-term affordability protections.
