Every Housing Cooperative establishes a set of membership application and eligibility criteria. Screening applications, while itself is not an unlawful practice if decisions do not violate the Fair Housing Act for discrimination against one or more protected classes (i.e., race or color, religion, sex, national origin, familial status or disability) or other relative federal, state and local laws, serves a legitimate purpose. These purposes include insuring that members can meet financial obligations, that members and their immediate family meet occupancy standards for certain sized dwelling units, and passing criminal background checks.
