The Department of Housing and Urban Development earlier this month issued a final disparate impact regulation under the Fair Housing Act (Final Rule). HUD’s new Final Rule is intended to align its disparate impact regulation, adopted in 2013 (2013 Rule), with the Supreme Court’s 2015 ruling in Texas Department of Housing and Community Affairs v. Inclusive Communities Project, Inc. (Inclusive Communities). While the new Final Rule is a notable development, the relatively recent Supreme Court decision makes it unclear to what extent courts and federal agencies will look to the rule for guidance.
