A.

A non-conforming use or structure may be continued but may not be altered or expanded. The expansion of a non-conforming use to a portion of a structure which was arranged or designed for the non-conforming use at the time of passage of this ordinance is not an enlargement or expansion of a non-conforming use. A non-conforming structure which conforms with respect to use may be altered or expanded if the alteration or expansion does not cause the structure to deviate further from the standards of this ordinance.

B.

If a non-conforming use is discontinued for six months, further use of the property shall conform to this ordinance.

C.

If a non-conforming use is replaced by another use, the new use shall conform to this ordinance.

D.

If a non-conforming structure or a structure containing a non-conforming use is destroyed by any cause to an extent exceeding eighty percent of its fair market value as indicated by the records of the county assessor, a future structure or use on the site shall conform to this ordinance. If a non-conforming structure is removed from the site, a future structure shall conform to this ordinance.

E.

Nothing contained in this ordinance shall require any change in the plans, construction, alteration or designated use of a structure for which a permit has been issued by the city and construction has commenced prior to the adoption of this ordinance provided the structure, if non-conforming or intended for a non-conforming use, is completed and in use within two years from the time the permit is issued.
