A. 
The lawful nonconforming use of a structure or land, including but not limited to fences, parking and zoning setbacks existing at the time of the adoption or amendment of this chapter may be continued although the use does not conform with the provisions of this chapter. However, only that portion of the land in actual use may be so continued and the structure may not be extended, enlarged, reconstructed, substituted, moved or structurally altered except when required to do so by law or order or so as to comply with the provisions of this chapter.
B. 
If no structural alterations are made, a nonconforming use of a building may be changed to any use permitted in the same use district as that in which the use existing is permitted according to the provisions of this chapter; provided when a use district is changed, any existing, nonconforming use in such changed district may be continued or changed to a use permitted in the same use district as that in which the existing use is permitted; provided all other regulations governing the new use are complied with.
C. 
Substitution of new equipment may be permitted by the Board of Zoning Appeals if such equipment will reduce the incompatibility of the nonconforming use with the neighboring uses. Normal maintenance is permitted. Any extension or enlargement of a nonconforming structure is subject to review and approval of the Plan Commission. This provision shall not be interpreted to disallow the extension or enlargement of a structure in respect to those dimensions that are in conformance with this chapter so long as additional nonconformities are not created thereby.
A. 
Termination. If such nonconforming use is discontinued or terminated for a period of 12 months, any future use of the structure or land shall conform to the provisions of this chapter.
B. 
Pursuant to § 62.23(7)(hc), Wis. Stats., a nonconforming structure damaged or destroyed by violent wind, vandalism, fire, flood, ice, snow, mold or infestation after March 2, 2006, may be restored to the size, location, and use that it had immediately before the damage or destruction occurred, and no limits may be imposed on the costs of the repair, reconstruction, or improvement of said structure. The size of the restored structure may be larger than the size it was immediately before the damage or destruction if necessary for the structure to comply with applicable state or federal requirements.[1]

Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II).
[Amended 4-11-2006 by Ord. No. 2006-11]
The lawful nonconforming structure existing at the time of the adoption or amendment of this chapter may be continued although its size or location does not conform with the lot width, lot area, yard, height, parking and loading, and access provisions of this chapter. Normal maintenance is permitted. Any extension or enlargement of a nonconforming structure is subject to review and approval of the City Plan Commission. This provision shall not be interpreted to disallow the extension or enlargement of a structure in respect to those dimensions that are in conformance with this chapter so long as additional nonconformities are not created thereby.
Once a nonconforming use or structure has been changed to conform, it shall not revert back to a nonconforming use or structure. Once the Board of Zoning Appeals has permitted the substitution of a more restrictive nonconforming use for an existing nonconforming use, the substituted use shall lose its status as a legal nonconforming use and become subject to all the conditions required by the Board of Zoning Appeals.
