All nonconforming uses and structures legally
existing at the time of the adoption of this chapter and all uses
and structures which become nonconforming by reason of amendment thereof
may be continued.
Nothing in this article shall be deemed to prevent
keeping in good repair a building in which a nonconforming use is
conducted.
A nonconforming use may be changed to another
nonconforming use of the same or a more restricted nature.
[Amended 5-20-1980 by Ord. No. 1723]
If any nonconforming use is abandoned for a
continuous period of two years or more, or is changed to or replaced
by a conforming use, or is moved for any distance for any reason,
the land and building theretofore devoted to such nonconforming use
shall thereupon be subject to all the regulations as to use for the
district in which such land and building are located as if such nonconforming
use had never existed.
