[Amended 11-17-2014 by Ord. No. 2014-05]
The lawful nonconforming use of a structure, land or water existing
at the time of adoption or amendment of this chapter may be continued
although the use does not conform to the provisions of this chapter.
However:
A.
Additions or alterations to existing nonconforming structures may
be permitted only where such additions or alterations do not increase
the degree of nonconformity by extending into the substandard yard
or setback greater than the existing structure and otherwise meet
all of the requirements of this chapter.
B.
Substitution of one nonconforming use by another nonconforming use
of equal or lesser degree of conformity may be permitted by the Zoning
Board of Appeals in accordance with the provisions of this chapter.
When a nonconforming use is damaged by fire, explosion, flood, public
enemy or other calamity to the extent of 50% of its current assessed
value, it shall not be restored except so as to comply with the provisions
of this chapter.
C.
Nothing
in this section shall prohibit the repair, maintenance, renovation,
remodeling or restoration of a nonconforming structure in accordance
with the provisions of § 62.23(7)(hb) and (hc), Wis. Stats.
If a nonconforming use is discontinued or terminated for a period
of 12 consecutive months, any future use of the structure, land, or
water shall conform to the provisions of this chapter.
Once a nonconforming structure or use has been changed to conform
to this chapter, it shall not revert back to a nonconforming use or
structure. Once the Zoning Board of Appeals has permitted the substitution
of a new nonconforming use for an existing nonconforming use, the
substituted use shall continue to be a nonconforming use subject to
the provisions of this article.
In any residential district a one-family detached dwelling and
its accessory structure may be erected on a legal lot or parcel of
record in the County Register of Deeds office before the effective
date of adoption or amendment of this chapter, provided that such
lots and parcels shall comply with all of the district requirements
insofar as practical, but such lots and parcels shall not be less
than the following:
