We conducted an annual limited scope review of the U.S. Department of Housing and Urban Development's (HUD) compliance with Presidential Executive Order (EO) 13520, Reducing Improper Payments. HUD was in general compliance with EO 13520 annual reporting requirements. We concluded that HUD's ongoing efforts in mitigating the risks of improper payments in the rental housing assistance programs were progressing in a positive direction. However, we noted some areas in which HUD could make enhancements related to disclosure and procedural issues. We also noted specific areas for improvements which would strengthen HUD's improper payment reduction strategies.
