This final rule revises HUD's regulations for Housing Assistance Payments contracts that were initially issued and administered by a State Housing Finance Agency. This final rule clarifies the meaning of the terms "HFA (Housing Finance Agency)" and "State Agency (Agency)" when HUD either assumes contract administration responsibilities or assigns the contract administration responsibilities to a Performance-Based Contract Administrator. This final rule also clarifies how reserve accounts may be transferred following assumption of contract administration duties by a new party. These regulatory changes conform with longstanding HUD policy and practice. This final rule adopts HUD's July 17, 2024, proposed rule without change.
