Statutorily Mandated Designation of Difficult Development Areas and Qualified Census Tracts for 2017

This document designates ``Difficult Development Areas'' (DDAs) and ``Qualified Census Tracts'' (QCTs) for purposes of the Low- Income Housing Tax Credit (LIHTC) under Internal Revenue Code (IRC) Section 42 (26 U.S.C. 42). The United States Department of Housing and Urban Development (HUD) makes new DDA and QCT designations annually. Unlike the effective date of the 2016 QCTs and DDAs, which was July 1, 2016, the 2017 QCTs and DDAs are effective January 1, 2017. In order to avoid designating areas unsuitable for residential development, such as airports, HUD is implementing a minimum population requirement for metropolitan Small Difficult Development Areas (SDDAs), as described below.
