Abandonment. A nonconforming use shall be considered to be abandoned if there occurs a cessation of the previous use or activity on the part of the owner or tenant for a period of one year from the date of cessation of use or activity, at which time such abandoned building, structure or premises shall not be put to a nonconforming use again.

Conversion to permitted use. Any nonconforming building or use which has been changed to a conforming use shall not be changed back again to a nonconforming use.

Restoration. Any nonconforming building or use which has been destroyed by fire, explosion, flood, windstorm or other act of God shall be considered partially destroyed if the cost of restoration equals up to one-half (1/2) the estimated equalized or true valuation of the building as determined by the Tax Assessor, and such building or use may be rebuilt, restored or repaired. If the damage is greater than one-half (1/2), the building or use shall be considered completely destroyed and shall not be rebuilt, restored or repaired unless in conformity with the building and use requirements of this chapter.

Repairs and alterations. A nonconforming building or structure may be repaired or maintained as required to keep it in sound condition. No structural alterations shall be made to any nonconforming structure or building except those that are required by law.
