HUD Housing Programs: Tenants’ Rights (The Green Book): 12.2.5.1 Introduction
Because of the normally long waiting list for public housing, the effective vacancy rates in well-managed projects should approach zero, reflecting only the very limited amount of time required to prepare a recently vacated unit for new occupants. In some projects, however, vacancy rates may be much higher. Most often this occurs because of poor management and maintenance policies, such as excessive turnover and inordinate delays in the process of preparing the units for new occupants.
