A. 
The lawful nonconforming use of a structure or land existing at the time of the adoption or amendment of this chapter may be continued although the use does not conform to 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. 
Total lifetime structural repairs or alterations shall not exceed 50% of the village's assessed value of the structure at the time of its becoming a nonconforming use unless it is permanently changed to conform to the use provisions of this chapter.
C. 
Substitution of new equipment may be permitted by the Zoning Board of Appeals if such equipment will reduce the incompatibility of the nonconforming use with the neighboring uses.
D. 
A lawful nonconforming use of a structure or land may conditionally be permitted to be extended, enlarged, or structurally altered only pursuant to the terms of this section and only if there is no negative impact on neighboring properties or their occupants. Whether to conditionally permit any extension, enlargement, or structural alteration of a nonconforming use or structure is a discretionary decision of the Plan Commission, and the Plan Commission may grant a request subject to certain conditions and/or for a certain term. Owners and operators of lawful nonconforming uses and structures do not have an automatic or vested right to extension, enlargement, or structural alteration. If permitted, any extension, enlargement, or structural alteration to a lawful nonconforming use or structure shall be deemed a conditional use for the zoning district in which the property is situated and shall be strictly limited to its terms. Any request to extend, enlarge, or structurally alter a lawful nonconforming use or structure must be made by application for a conditional use permit as set forth in § 298-29. A hearing on the application for a conditional use permit shall be held in accordance with § 298-30. No request to extend, enlarge, or structurally alter a lawful nonconforming use or structure may be granted unless the Plan Commission finds that all of the conditions identified in § 298-32 of this chapter are present and that there is no negative impact on neighboring properties or their occupants. If a conditional use permit is granted to authorize the extension, enlargement, or structural alteration of a lawful nonconforming use or structure, the conditional use permit shall be subject to all of the ordinances governing conditional use permits.
[Added 3-13-2024; amended 3-13-2024]
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. When a nonconforming use or structure is damaged by fire, explosion, flood, the public enemy or other calamity to the extent of more than 50% of its current assessed value, it shall not be restored except so as to comply with the use provisions of this chapter.
A 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 to the lot width, lot area, yard, height, parking and loading and access provisions of this chapter. However, it shall not be extended, enlarged, reconstructed, 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.
Once a nonconforming use or structure has been changed to conform, it shall not revert back to a nonconforming use or structure. Once the Zoning Board of 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 Zoning Board of Appeals.
