A nonconforming use shall be presumed to be abandoned when there occurs a cessation of such use or activity by an apparent act or failure to act on the part of the tenant, user, occupier or owner to reinstate such use within a period of one (1) year from the date of such cessation or discontinuance. Such use shall not thereafter be reinstated and the structure shall not be reoccupied, unless and until the building or structure shall conform to the regulation contained in this Chapter for the district in which such lot is located. Further, the change of a nonconforming use to a permitted use in the district in which the lot is located by such tenant, user, occupier or owner shall constitute an immediate abandonment of the nonconforming use.
