Insofar as the standards in this article are not inconsistent
with the provisions of §§ 59.69(10) and 62.23(7)(h),
Wis. Stats., they shall apply to all nonconforming structures and
nonconforming uses. These regulations apply to the modification of,
or addition to, any structure and to the use of any structure or premises
which was lawful before passage of this chapter or any amendment thereto.
The existing lawful use of a structure or building or its accessory
use which is not in conformity with the provisions of this chapter
may be continued, subject to the following conditions:
A. No modifications or additions to a nonconforming use shall be permitted
unless they are made in conformity with the provisions of this article.
For the purposes of this article, the words "modification" and "addition"
shall include, but not be limited to, any alteration, addition, modification,
structural repair, rebuilding or replacement of any such existing
use, structure or accessory structure or use. Ordinary maintenance
repairs are not considered structural repairs, modifications or additions;
such ordinary maintenance repairs include internal and external painting,
decorating, paneling and the replacement of doors, windows and other
nonstructural components;
B. If a nonconforming use is discontinued for 12 consecutive months,
it is no longer permitted, and any future use of the property and
any structure or building thereon shall be made to conform to the
applicable requirements of this chapter.
C. As requests are received for modifications or additions to nonconforming
uses or nonconforming structures in the floodway, a record shall be
kept which lists the nonconforming uses and nonconforming structures,
their present equalized assessed value, and the cost of those additions
or modifications which have been permitted.
D. No modification or addition to any nonconforming structure or any structure with a nonconforming use which, over the life of the structure, would exceed 50% of its present equalized assessed value shall be allowed unless the entire structure is permanently changed to a conforming structure with a conforming use in compliance with the applicable requirements of this chapter, and contiguous dry land access is provided in compliance with §
548-20B(3) or
(4).
