All lawful uses of land or of a building or other structure
existing on the effective date of this chapter may be continued, altered,
restored, reconstructed, sold, or maintained even though such use
may not conform to the use, height, area, yard, and other regulations
of the district in which it is located, providing such nonconforming
uses shall comply with the provision of this article.
Whenever a nonconforming use has been changed to a conforming
use, such use shall not thereafter be changed to a nonconforming use.
If a nonconforming use of a structure or land ceases or is discontinued
for a continuous period of one year or more, the nonconforming use
shall be considered to be abandoned, and subsequent use of such structure
or land shall be in conformity with all the provisions of this article.
This standard shall not apply in cases where the cessation or discontinuance
was caused by circumstances beyond the control of the owner.
Any lot held in single and separate ownership at the effective
date of this chapter and which does not conform to one or more of
the applicable dimensional regulations in the district in which it
is located shall be considered nonconforming. A building may be erected
upon a nonconforming lot and a use may be established upon a nonconforming
lot, provided a zoning permit is obtained in accordance with the provisions
of this chapter. Such development shall comply with the following
provisions:
A. The proposed use is permitted by right within the district in which
it is located.
B. The proposed building and use shall comply with all applicable area,
height, and bulk regulations of the district other than the regulation(s)
that result in the lot being considered to be nonconforming. Zoning
permit approval shall not be granted for lots that are nonconforming
with regard to minimum lot area, and where the underlying zoning district
applies a minimum lot area standard for a specific use that exceeds
the generally required minimum lot area standard for the zoning district
as a whole.
