If a lawful use of a structure, or of a structure and premises in combination, exists at the effective date of adoption of this chapter, that would not be allowed in the district under the terms of this chapter, the lawful use may be continued as long as it remains otherwise lawful, subject to the provisions of divisions (A) though (E) below.
(A) No existing structure devoted to a use not permitted by this chapter shall be enlarged, extended, constructed, moved or structurally altered except in changing the use of the structure to a use permitted in the district in which it is located.
(B) Any nonconforming use may be extended throughout any parts of a building which were manifestly arranged or designed for use at the time of adoption or amendment of this chapter, but no use shall be extended to occupy any land outside the building.
(C) (1) If no structural alterations are made, any nonconforming use of a structure, or a structure and premises, may be changed to another nonconforming use, provided the Board of Zoning Appeals, either by general rule or by making findings in the specific case, shall find that the proposed use is equally appropriate or more appropriate to the district than the existing nonconforming use.
(2) In permitting the change, the Board of Zoning Appeals may require appropriate conditions and safeguards in accord with the provisions of this chapter.
(D) (1) When a nonconforming use of a structure, or a structure and premises in combination, is discontinued or abandoned for 6 consecutive months during 1 full calendar year or for 18 months during any 3-year period, the structure or the structure and premises in combination shall not thereafter be used except in conformance with regulations of the district in which it is located.
(2) This provision does not apply to a seasonal business.
(E) A seasonal business which is a nonconforming use that does not operate for at least 4 consecutive months during 1 full calendar year shall be deemed to be discontinued or abandoned and the structure shall not thereafter be used except in conformance with regulations of the district in which it is located.
