In case the buildings at any institution are destroyed or rendered unfit for habitation by reason of fire, storms, or other like causes, to such an extent that the residents cannot be housed and cared for, the director shall make temporary provision for the housing and care of the residents at some other place in the state. Like provision may be made in case any pestilence breaks out among the residents. The reasonable cost of the change, including transfer of residents, shall be paid from any moneys in the state treasury not otherwise appropriated.
