Any nonconforming uses or structures existing as of the date
of adoption of this chapter, or which became nonconforming as a result
of the adoption of this chapter, may be continued upon the lot or
in the building so occupied, and any structure may be restored or
repaired in the event of partial destruction thereof.
No nonconforming building may be enlarged or expanded to cover
a larger area than it occupied at the date of adoption of this chapter,
except that where an existing lot is improved with a building or structure
which is nonconforming due to location, such lot may be further improved
by an addition to such building or structure, provided that the existing
nonconforming setbacks may be extended but not further encroached
upon. No nonconforming use may be extended or expanded over a larger
area than it occupied at the time of enactment of this chapter, any
nonconforming single-family residence located in any nonresidential
district where residences are prohibited may be expanded, provided
that yard areas as required in the SF Zone shall be applicable to
such property and shall not be encroached upon, and further provided
that the expanded structure shall continue to be used as a single-family
residence.
After a nonconforming building or use has been converted to
a permitted use, it shall not be changed back again to a nonconforming
use.
If a nonconforming use has been abandoned, such use shall not
be recommenced. Cessation of a nonconforming use for a continuous
period of one year may be taken as prima facie evidence of an intent
to abandon such use.
