Information for tenants. Several requirements exist for tenant qualification and an acceptable rental unit. Each housing authority requires anyone who applies to meet specific criteria. Each family must meet the Housing Authority’s definition of a family, and each member must produce their Social Security number or get one. Also, each member must be a U.S. citizen or an eligible immigrant. In addition, violations of any rule within the Housing Authority guidelines will cause a denial of assistance. An acceptable rental unit must meet the definition of an eligible unit set by the Department of Housing and Urban Development and its Section 8 Housing Quality Standards.
