(4) The provider shall have the burden of proving, by a preponderance of evidence, the propriety of the proposed eviction, but all such evidence shall be within the scope of the reasons for eviction set forth in the notice required by paragraph (2). An eviction under this section shall be deemed proper if the occupant has substantially violated an essential provision of a written agreement containing the conditions of occupancy or if the occupant is likely, in spite of reasonable accommodation, to impair the emotional or physical well being of other occupants, program staff or neighbors.
