A.

Continuance. Any lawful building structure, building permit issued or use existing on, or prior to, the adoption of this ordinance, or whenever a district shall be changed by amendment to this ordinance, may be continued, although such building, structure or use does not conform to the regulations of the district in which it is located.

B.

Alterations or repairs. [Alterations or repairs] are permitted to a structure that enjoys a legal nonconforming use only where there is no increase in the cubical content of such building.

C.

Abandonment of [a nonconforming use], or restoration after damage. No nonconforming use may be reestablished where such nonconforming use has been discontinued for a period of at least six months; except that a structure damaged by an act of God, war or local catastrophe may be re-established if there is no increase in the cubical content of the original building. For purposes of this ordinance, a local catastrophe shall include soil subsidence, termite infestation and condemnation by the regulatory director.

D.

Change in use. A nonconforming use may be changed to one of a similar or higher classification, but no building or structure in which a nonconforming use has been changed to a more restricted nonconforming use shall again be devoted to a less restrictive use. A building or structure which has a nonconforming use that does not invoke or permit the sale and consumption of alcoholic beverages on the premises shall not be changed to a use which involves, permits or authorizes the sale and consumption of alcoholic beverages on the premises. Any change in use shall conform to all required regulations.

E.

Discontinuance of nonconforming use of land. The nonconforming use of land shall be discontinued immediately upon adoption of this ordinance where no buildings are employed in connection with such uses.

F.

Limitation of nonconforming use of land. Where a portion of property occupied by a nonconforming structure is used as nonconforming, but the use does not include the entire lot or parcel, the portion not used shall not be deemed to be nonconforming.
