(a)

Continuation. The lawful nonconforming use of a structure, land or water existing at the time of the adoption or amendment of the ordinance from which this chapter is derived may be continued although the use does not conform with the provisions of this chapter; provided, however:

(1)

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.

(2)

The total lifetime structural repairs or alterations shall not exceed 50 percent of the assessed value of the structure at the time of it becoming a nonconforming use unless it is permanently changed to conform to the use provisions of this chapter.

(3)

Substitution of new equipment may be permitted by the council if such equipment will reduce the incompatibility of the nonconforming use with the neighboring uses.

(b)

Abolishment or replacement of existing nonconforming use. If such nonconforming use is discontinued or terminated for a period of 12 months, any future use of the structure, land or water 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 percent of its current equalized assessed value, it shall not be restored except so as to comply with the use provisions of this chapter (Exception: Wis. Stats. § 62.23(7)(hc)). From the date of adoption of the ordinance from which this chapter is derived, a current file of all nonconforming uses shall be maintained, listing the following:

(1)

Owner's name and address.

(2)

Use of the structure, land or water.

(3)

Assessed value at the time of it becoming a nonconforming use.

(Code 2006, § 17.05(1))

Any lawful nonconforming structures existing at the time of the adoption or amendment of the ordinance from which this chapter is derived 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. 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.

(Code 2006, § 17.05(2))

Once a nonconforming use or structure has been changed to conform, it shall not revert back to a nonconforming use or structure. Once the common council 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 common council.

(Code 2006, § 17.05(3))

An existing lot which does not contain sufficient area to conform to the dimensional requirements of this chapter, but which is at least 66 feet wide and 8,712 square feet in area, may be used as a single-family building site, provided that the use is permitted in the zoning district and the lot is of record in the county register of deed's office prior to the effective date of the ordinance from which this chapter is derived; and, further provided, that the lot is in separate ownership from abutting lands. If two or more substandard lots with continuous frontage have the same ownership as of the effective date of the ordinance from which this chapter is derived, the lots involved shall be considered to be an individual parcel for the purpose of this chapter. Substandard lots shall be required to meet the setbacks and other yard requirements of this chapter. A building permit for the improvement of a lot with lesser dimensions and requisites than those stated above shall be issued only after approval of a variance by the board of zoning appeals.
