The lawful use of any building or land existing at the time
of the enactment of this chapter may be continued, although, such
use does not conform with the provisions of this chapter. All preexisting
uses which do not conform with specific provisions of this chapter
shall not be required to comply with these provisions unless it is
specifically stated within this chapter that they must comply within
a certain reasonable time period.
Nothing herein contained shall require any change in plan, construction,
or designated use of building for which a building permit has been
heretofore issued and the construction of which shall have been diligently
carried on within three months of the date of such permit.
Whenever a nonconforming use has been voluntarily discontinued
for a period of one year, such use shall not thereafter be reestablished,
and any future use shall be in conformity with the provisions of this
chapter.
No nonconforming use shall be extended to displace a conforming
use.
Whenever the boundaries of a district or zone shall be changed
so as to transfer an area from one district or zone to another district
or zone of a different classification, the provisions of this article
shall also apply to nonconforming uses existing therein.
An allowed use which is not in conformance with yard requirements
(e.g., setbacks, etc.) may be removed and replaced with another structure
(same use) which is more in compliance with the yard requirements
without going through area variance procedures. The Enforcement Officer
shall determine the applicability of this section to specific cases.
