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 Rental Certificate, 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.
