The Eleventh Circuit joins other courts that have held that sexual harassment by a landlord (or an agent of the landlord) can constitute sex discrimination in violation of the Fair Housing Act, 42 U.S.C. §3601 to §3613 if the behavior would not have occurred but for the tenant's sex.
This formulation has been adopted by other courts, see United States v. Hurt, 676 F.3d 649 (9th Cir. 2012), Quigley v. Winter, 598 F.3d 938 (8th Cir. 2010), and suggests that a landlord that sexually harasses both men and women would not be liable for engaging in sex discrimination — a result that would enable landlords to insulate themselves from liability by choosing to harass tenants indiscriminately.
