We audited the Allegheny County Housing Authority’s Housing Choice Voucher program because (1) the Authority received more than $27.3 million in Housing Choice Voucher funding in fiscal year 2011, (2) an article in the October 22, 2011, Pittsburgh Post-Gazette described housing quality standards problems with a housing unit participating in the Authority’s program, and (3) we had never audited the Authority’s Housing Choice Voucher program. The audit objective was to determine whether the Authority ensured that its Housing Choice Voucher program units met the U.S. Department of Housing and Urban Development's (HUD) housing quality standards. The Authority did not conduct adequate inspections to ensure that its program units met housing quality standards as required. Of 70 program units statistically selected for inspection, 57 did not meet HUD's housing quality standards. Moreover, 26 of the 57 units were in material noncompliance with housing quality standards. The Authority disbursed $14,535 in housing assistance payments and received $535 in administrative fees for these 26 units. We recommended that HUD require the Authority to (1) reimburse its program $15,070 from non-Federal funds for the 26 units that materially failed to meet HUD’s housing quality standards and (2) use the results of this audit to train all of its inspectors to ensure that program units meet housing quality standards, thereby ensuring that $5.2 million in program funds is expended for units that are decent, safe, and sanitary.
