The purpose of this part is to require Public Housing Agencies (PHAs), including Moving-to-Work (MTW) PHAs, that operate Public Housing, Indian Housing, or Section 8 Housing Choice Voucher (HCV), Rental Voucher, and Moderate Rehabilitation programs to electronically submit certain data to HUD for those programs. These electronically submitted data are required for HUD forms: HUD-50058, including the Family Self-Sufficiency (FSS) Addendum. Applicable program entities must retain at a minimum, the last three years of the form HUD-50058, and supporting documentation, during the term of each assisted lease, and for a period of at least 3 years from the end of participation (EOP) date, to support billings to HUD and to permit an effective audit. Electronic retention of form HUD-50058 and HUD-50058-FSS and supporting documentation fulfills the record retention requirement under this section.
