(A) This category of nonconformance consists of buildings or structures used at the time of enactment of this chapter for purposes of use not permitted in the district in which they are located.
(B) Such uses may be continued as follows.
(1) A nonconforming use shall not be changed to another nonconforming use.
(2) When a nonconforming use has been changed to a conforming use, it shall not thereafter revert to any nonconforming use.
(3) A nonconforming use may not be extended or enlarged, nor shall a nonconforming structure be altered except as follows.
(a) Structural alterations as required by law or ordinance to secure the safety of the structure are permissible.
(b) Maintenance and repair necessary to keep a nonconforming structure in sound condition are permissible.
(c) Expansion of a nonconforming use of a building or structure into portions of the structure which, at the time the use became nonconforming, were already erected and arranged or designed for such nonconforming use is permissible.
(d) In cases where the enlargement or extension shall result in bringing the structure up to the minimum square footage requirement for the district in which it is located, or otherwise change the structure to a conforming use.
(4) When any nonconforming use of a building or structure is discontinued for a period in excess of 180 days, the building or structure shall not thereafter be used except in conformance with the regulations of the district in which it is located. Vacancy and/or non-use of the structure, regardless of the intent of the owner or tenant, shall constitute discontinuance under this provision.
