By issuing its Disparate Impact regulations, HUD formalized “its long-held recognition of discriminatory effects liability under the Act and, for purposes of providing consistency nationwide, formalizes a burden-shifting test for determining whether a given practice has an unjustified discriminatory effect, leading to liability under the Act. This final rule also adds to, and revises, illustrations of discriminatory housing practices found in HUD’s Fair Housing Act regulations.”
