A nonconforming status shall exist when a use or structure which does not conform to the regulations prescribed in the district in which such use or structure is located was in existence and lawfully operating prior to the adoption of the Zoning Ordinance.

No nonconforming use or structure may be expanded or increased beyond the existing extent or level of intensity of the current nonconforming use or structure as of the effective date of this ordinance, except to provide off-street loading or off-street parking space upon approval of the City Council.

Repairs and normal maintenance may be made to a nonconforming building provided that no structural alterations or extensions shall be made except those required by law or ordinance, unless the building is changed to a conforming use.

Any nonconforming use may be changed to a conforming use and once such change is made, the use shall not thereafter be changed back to a nonconforming use.

Whenever a nonconforming use is abandoned, all nonconforming rights shall cease, and the use of the premises shall thenceforth be in conformity with this ordinance. Abandonment shall involve the intent of the user or owner to discontinue a nonconforming operation and the actual act of discontinuance. Discontinuance of a business or the vacancy of a building or premises occupied by a nonconforming use for a period of six (6) months shall be construed as conclusive proof of intent to abandon the nonconforming use. Any nonconforming use not involving a permanent type of structure which is moved from the premises shall be considered to have been abandoned.

If a nonconforming structure or a structure occupied by a nonconforming use is destroyed by fire, act of God or other cause, it may not be rebuilt as a nonconforming structure or use except to the provisions of this ordinance. In the case of partial destruction of a nonconforming structure or use not exceeding fifty percent (50%) of its market value, reconstruction may be permitted after a hearing and favorable action by the City Council, but the size and function of the nonconforming use shall not be expanded.

Notwithstanding any of the provisions of this section, a nonconforming HUD-Code manufactured home may be exchanged or replaced by another HUD-Code manufactured home.
