It is the purpose of this Act to preserve and retain to the maximum extent practicable, as housing affordable to low and moderate income families or persons, those privately owned dwelling units that were provided for such purposes with federal assistance, to minimize the involuntary displacement of tenants currently residing in such housing, to ensure that the appropriate governmental authorities are given adequate notice to respond to the potential problems created by conversions of subsidized rental units to nonsubsidized rental units and to ensure that the subsidized rental unit occupants are provided with information and assistance, in the event of conversions.
