HUD has published a notice in the Federal Register announcing the FY-2013 Annual Adjustment Factors (AFF) for adjustment of contract rents for units assisted in certain Section 8 housing assistance payment programs during the initial (i.e., pre-renewal) term of the HAP contract and for all units in the Project-Based Certificate program. Each Section 8 program category uses the AAFs differently and AAFs are not used in determining renewal rents, budget-based rents, or for the Tenant-Based Certificate program. AFFs are based on a formula using residential rent and utility cost changes from the Labor Bureau’s most recent Consumer Price Index (CPI) survey. The notice provides a broad description of procedures for adjusting the contract rent. These adjustment factors are effective May 22, 2013. A separate notice will be published that will identify the inflation factors that will be used to adjust tenant-based rental assistance funding for FY-2013.
