HUD Designates 2027 Difficult Development Areas for Housing Incentives
Published Date: 10/6/2026
Notice
Summary
Every year, HUD picks special neighborhoods called Difficult Development Areas (DDAs) and Qualified Census Tracts (QCTs) where building affordable housing is extra tough or important. These designations help decide where developers can get tax credits to build low-income homes. The new 2027 list affects developers and communities by guiding where money-saving incentives apply, helping more affordable housing get built on time.
Analyzed Economic Effects
6 provisions identified: 3 benefits, 2 costs, 1 mixed.
Extra LIHTC Basis in DDAs and QCTs
If your building is located in a 2027 Difficult Development Area (DDA) or a 2027 Qualified Census Tract (QCT), the project's eligible basis may be increased up to 130 percent (an increase of up to 30 percent). That increase raises the amount of Low-Income Housing Tax Credit (LIHTC) available to the project.
2027 Designations Effective Date and 730-Day Rule
The 2027 DDA and QCT lists apply for allocations of credit after December 31, 2026, and for bonds/buildings placed in service after that date. If an area loses designation later, a project remains eligible under the 2027 list only if the allocation (or bond issuance/placement in service) occurs no later than 730 days after a complete application was filed before the subsequent list's effective date.
Multiphase Projects Inherit 2027 Status
For a multiphase project, the DDA or QCT status that applies is the status in effect when the project received its first allocation of LIHTC (or when the bonds were issued/first building placed in service for IRC Section 42(h)(4)). To qualify, the first application must describe the multiphase composition, aggregate credits must exceed single-year limits necessitating multiple allocations, and applications must be filed in immediately consecutive years.
States May Grant 30% Basis Boost Outside Designations
States may award an increase in basis up to 30 percent to buildings located outside federally designated DDAs and QCTs if the increase is necessary to make the building financially feasible. This state-authorized increase applies only to buildings allocated credits under the state's housing credit ceiling and not to bond-financed credits.
Population Caps Limit Where Designations Apply
HUD limited DDA designations so metropolitan DDAs (taken together) may not contain more than 20 percent of the aggregate metropolitan population and nonmetropolitan DDAs may not contain more than 20 percent of the aggregate nonmetropolitan population. QCT designations in any single metropolitan or nonmetropolitan area may not contain more than 20 percent of that area's population.
An Area Cannot Be Both DDA and QCT
HUD will not designate the same area as both a DDA and a QCT for 2027; an area can be designated as a QCT or a DDA, but not both.

2026-16228, HUD's Implementation of the Fair Housing Act's Disparate Impact Standard; Amendments to HUD's Title VI Regulations
HUD published a notice of proposed rulemaking in January of 2026 that proposed to remove HUD's disparate-impact regulations and leave interpretation of disparate-impact liability under the Fair Housing Act to the courts. This supplemental notice of proposed rulemaking continues HUD's efforts to remove or revise regulations that prohibit conduct having a disparate impact without evidence of discriminatory intent. Through this rule, HUD is proposing to remove provisions in HUD's Title VI implementing regulations that impose disparate-impact liability on recipients of HUD Federal financial assistance. If finalized, this rule would improve consistency within HUD's own regulations and between HUD's regulations and the Title VI regulations recently revised by the Department of Justice (DOJ). This rule reopens the public comment period of HUD's January 2026 proposed rule on disparate-impact liability; HUD will only consider comments on topics related to this supplemental notice of proposed rulemaking during the reopened comment period.
