If a lawful use of a structure or of structures and premises in combination exists at the effective date of adoption or amendment of this title that would not be allowed in the district under the terms of this title, the lawful use may be continued subject to the following conditions:
A. No existing structure devoted to a use not permitted in the district in which it is located shall be enlarged, extended, constructed, reconstructed or structurally altered except in changing the use of the structure to a use permitted in the district in which it is located, nor shall the intensity of such use be increased or extended, except that the planning and zoning commission, by special permit in the case of an affirmative showing of undue hardship may grant an extension or enlargement of a nonconforming use not exceeding twenty five percent (25%) of the ground area of the building.
B. Any nonconforming use may be extended throughout any parts of a building that were manifestly arranged or designed for such use at the time of adoption or amendment of this title, but no such use shall be extended to occupy any land outside such building.
C. When a nonconforming use of a structure or a structure and premises in combination is discontinued or abandoned for a period of one year, the structure or structure and premises in combination shall not, thereafter, be used except in conformance with the regulations of the district in which it is located.
D. Any nonconforming building or structure damaged more than sixty percent (60%) of its then fair market value, exclusive of the foundations, at the time of damage by fire, flood, explosion, war, riot or act of God, shall not be restored or reconstructed and used as before such happening, but if less than sixty percent (60%) is damaged above the foundation, it may be restored, reconstructed or used as before, provided that it may be done within four (4) months of such happening and be built of like or similar or better materials.
E. If any such nonconforming use of land ceases for any reason for a period of not more than one year, any subsequent use of such land shall conform to regulations specified by this title for the district in which said land is located.
F. In areas where the grazing and feeding of livestock are not allowed, if the use of the land for grazing purposes ceases for any reason for a period of more than one year, any subsequent use of such land shall conform to the regulations specified in this title for the district in which such land is located.
