NON-CONFORMING USES
1. Any lawful use of building or land at the time of the passage of this ordinance that does not conform to the regulations prescribed in this ordinance shall be deemed a non-conforming use, and such may be continued, but if such non-conforming use is discontinued for the period of one year or more, except for residential structures and accessory farm buildings, any future use of said building or land must be in conformity with the provisions of this ordinance. A non-conforming use, may be extended to more floor area throughout a building. A non-conforming use, if changed to a conforming use, may not thereafter be changed back to any non-conforming use.
2. Repairs and structural alterations may be made to a non-conforming building, provided that the floor space of such building is not increased.

A non-conforming building or structure which is damaged or partially destroyed by fire, flood, wind, earthquake, or other calamity, or act of God, or public enemy, to the extent of not more than two and one-half (2 ½) times its assessed value at the time, may be restored and the occupancy or use of such building or structure or part thereof, which existed at the time of such partial destruction, may be continued or resumed, provided that such restoration is started within a period of one (1) year and is diligently prosecuted to completion. In the event such damage or destruction exceeds two and one-half (2 ½) times the assessed valuation of such non-conforming building or structure, no repairs or reconstruction, except in case of dwelling structures and accessory farm buildings, shall be made unless every part of such buildings or structure is made to conform to all regulations for new buildings in the zone in which it is located.
