Where, at the time of adoption or amendment of this Ordinance, lawful uses of land exist which would not be permitted by the regulations imposed by this Ordinance, the uses may be continued so long as they remain otherwise lawful, provided:
A. The non-conforming use may not be enlarged or increased unless approval by the Board of Zoning Appeals has been granted to the applicant.
B. A non-conforming use may be extended throughout a building which was designed and arranged for such use if no structural alterations are made, except those required by law.
C. If a non-conforming use of any lot, building, or structure and of any lot or premises is voluntarily discontinued or abandoned for a period of one (1) year (except when government action impedes access to the premises), any subsequent use of such lot, building, or structure shall conform to the regulations specified by this Ordinance for the district in which such land is located.
D. With approval from the Board of Zoning Appeals, the extension of a non- conforming use may be permitted where modifications make the non-conforming use more compatible or less in conflict with the character of the district than the existing non-conforming use.
E. The adoption or amendment of this Ordinance does not legalize any illegal use existing at the time of its adoption
