A. 
Continuance. Except as otherwise required by law, a structure or use legally established prior to the adoption date of this Code may be maintained unchanged. In other than criminal proceedings, the owner, occupant or user shall have the burden to show us that the structure, lot or use was lawfully established.
B. 
If no structural alterations are made, a non-conforming use of a building may be changed to another non-conforming use of the same or of a more restricted classification. Whenever a non-conforming use has been changed to a more restricted use or to a conforming use, such use shall not thereafter be changed to a less restricted use.
C. 
Whenever the use of a building becomes non-conforming through a change in zoning requirements or district boundaries, such use may be continued and if no structural alterations are made, it may be changed to another non-conforming use of the same or of a more restricted classification.

A. 
Vacancy. Any lot or structure or portion thereof occupied by a non-conforming use which is or hereafter becomes vacant and remains unoccupied by a non-conforming use for a period of twelve (12) months shall not thereafter be occupied, except by a use that conforms to this Code.
B. 
Damage. Any building or structure containing a non-conforming use which is damaged by fire, flood, wind or other act of God or man to the extent of fifty percent (50%) or more of its fair sales value immediately prior to damage shall not be repaired or reconstructed except in conformity with the provisions of this Title. In the event that the Code Official's estimate of the extent of damage of fair sales value is not acceptable to the applicant for the building permit to repair or reconstruct such building or structure, the applicant may appeal to the Board of Adjustment.
