A house, trailer, vessel designed for habitation, or portion of a building is currently being used for dwelling purposes if, at the time of the burglary, it was not occupied solely because a natural or other disaster caused the occupants to leave the premises.

(b) The fact that the structure entered has been damaged by a natural or other disaster, or the extent of that damage, does not preclude conviction.
