On December 27, 2018, HUD announced Section 8 Annual Adjustment Factors for Fiscal Year 2019 in the Federal Register. The notification includes a link to the AAF data (https://www.huduser.gov/portal/datasets/aaf.html) however, at this time nothing has been posted and it is not clear what the effective date of the new AAFs will be. In the past, there has often been a HUD notice indicating the effective. Currently no such notice has been published.
It is unclear whether the current government shutdown will impact the posting of the data.
