The Department of Housing and Urban Development hit Facebook Inc. with an administrative complaint alleging the social media company’s advertising tools enable those managing property to discriminate in housing.

Filed on Aug. 14, HUD’s administrative complaint alleges that both the social media company’s ad targeting tools and user classification enable the limitation of ad audiences on characteristics “outright prohibited” by the Federal Housing Administration, said the government’s formal statement of interest. Among the grounds on which Facebook is alleged to have allowed discrimination are “sex, religion, familial status, and natural origin, and pretexts for protected characteristics.”
