The provisions of this section apply to nonconforming
uses, structures and lots so created by the initial enactment of this
chapter or by any subsequent amendment.
Any nonconforming structure, totally destroyed
by fire or other cause, may be rebuilt within one year but shall not
be rebuilt to be nonconforming to a greater degree than the original.
Any nonconforming use of a structure or lot
which has been abandoned or not used for a continuous period of two
years or more shall not be used again, except for a conforming use.
Any nonconforming structure shall not be moved
to any other location on the lot, or any other lot, unless every portion
of such structure, the use thereof and the lot shall be conforming.
Any structure determined to be unsafe may be
restored to a safe condition. Such work on any nonconforming structure
shall not place it in greater nonconformity. If the cost to restore
any structure shall exceed 50% of its physical replacement value,
it shall be reconstructed only as a conforming structure and used
only for a conforming use.
