On December 4, 2015, the President signed the Fixing America’s Surface Transportation Act (FAST Act) into law. The law contained language that allowed public housing authorities (PHAs) and owners to conduct full income recertifications for families with 90 percent or more of their income from fixed-income every three years instead of annually. HUD issued an interim rule on December 12, 2017, to align the current regulatory flexibilities with those provided in the FAST Act. In addition, the interim rule sought to extend to certain multifamily housing (MFH) programs some of the streamlining changes that were proposed for and made only to the housing choice voucher (HCV) and public housing (PH) programs. This final rule finalizes the regulatory language to implement the FAST Act contained in the December 2017 interim rule, with one change to clarify that owners are not required to make adjustments to non-fixed-income. The final rule is effective as of June 8, 2020.
