The Fair Housing Act (or Act) prohibits discrimination in the sale, rental, or financing of dwellings and in other housing-related activities on the basis of race, color, religion, sex, disability, familial status or national origin.1 HUD’s Office of General Counsel issues this guidance concerning how the Fair Housing Act applies to the use of criminal history by providers or operators of housing and real-estate related transactions. Specifically, this guidance addresses how the discriminatory effects and disparate treatment methods of proof apply in Fair Housing Act cases in which a housing provider justifies an adverse housing action – such as a refusal to rent or renew a lease – based on an individual’s criminal history.
