The lawful nonconforming use of a structure, land or water 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 or water 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.

Total lifetime structural repairs or alterations shall not exceed 50% of the City'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.

If any nonconforming use is discontinued or terminated for a period of 12 months, future use of the structure, land or water shall conform to the provisions of this chapter.

When a nonconforming use or structure is damaged or destroyed by violent wind, vandalism, fire, flood, ice, snow, mold, or infestation, before March 2, 2006, 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. When a nonconforming use or structure is damaged or destroyed by violent wind, vandalism, fire, flood, ice, snow, mold, or infestation on or after March 2, 2006, it can be restored to the size, location, and use that it had immediately before the damage or destruction occurred, except that the size of the structure can 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.

A current file of all nonconforming uses and structures shall be maintained by the Building Inspector listing the following: property location, use of the structure, land, or water, and the date that the structure or use became nonconforming.[1]

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 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.
