The existing lawful use of a structure or premises at the time of the enactment of this chapter or any amendment applicable thereto, which use is not in conformity with the provisions established by this chapter, may be continued in the manner and for the purposes then existent subject to the conditions hereinafter stated.
For the purpose of administration, such nonconformity shall be classified and regulated as follows:
A. 
Nonconforming structure.

Restoration of significantly damaged structures. A nonconforming structure damaged or destroyed by violent wind, vandalism, fire, flood, ice, snow, mold or infestation shall be restored in accordance with the provisions of § 62.23(7)(hc), Wis. Stats.

Facades. In the commercial districts, if more than 50% of the area of a nonconforming facade is replaced, the entire facade must conform to the facade regulations of an allowed building type in the district per § 535-22 and with the building design regulations in § 535-23, except as defined in Subsection A(2) of this section.

No such use shall be expanded or enlarged except in conformity with the use regulations of the district in which the structure is located.
(2) 
Upon petition to and approval of the Plan Commission, such use may be changed to another use, provided that the Plan Commission determines that the new use would result in greater or no less degree of conformity and provided further that such new use shall thereafter determine the degree of legal nonconformity.
(3) 
When any such use is discontinued for a period of 12 consecutive months, any further use of the building shall conform to the regulations of the district in which it is located.

Where the building in which such use is carried on is damaged to the extent of more than 50% of its current assessed value as equalized, it shall not be restored for use except in conformity with the regulations of the district in which it is located.

(2) 
No building permit shall be issued except in conformity with the provisions of § 535-9 of this chapter.

Special exceptions.
(1) 
Subject to the provisions of applicable state law, the Board of Appeals, upon application as required herein, may grant a special exception to the provisions of Subsection A hereof after considering:

Within a reasonable time after said hearing, the Board of Appeals shall either approve or disapprove the application for special exception hereunder, in accordance with the provisions of this Subsection E.
Where, upon complaint of the Zoning Administrator, Building Inspector or Chief of Police or Chief of Fire, any nonconforming structure or use is found by the Plan Commission as a matter of fact to be a hazard to the public health, safety or general welfare, such structure may be ordered removed or such use may be ordered discontinued within such time as the Plan Commission may deem reasonable. Upon failure to carry out such order, the Village may take such steps as are necessary to remove such structure or discontinue such use and assess the cost thereof against the property owner.
