A letter report issued by the Government Accountability Office with an abstract that begins "In light of the pressing need for rental housing affordable to low-income households and concerns that the Department of Housing and Urban Development (HUD) may not be committed to maintaining its Section 8 project-based housing stock--a key source of such housing--Congress directed GAO to assess HUD's efforts to preserve its project-based housing and recommend ways to improve these efforts. This report discusses (1) patterns in the volume and characteristics of HUD's Section 8 project-based properties; (2) tools and incentives that are available to encourage property owners to stay in the program; and (3) the views of property owners, managers, and industry representatives on HUD's preservation efforts. To address these issues, GAO analyzed HUD data, reviewed pertinent legislation and regulations, and interviewed HUD officials and industry representatives.
