The general purpose of regulating nonconforming uses, structures
and lots is to allow for the continued existence of such uses, structures
and lots after a zoning change which would otherwise prohibit such
use, structure or lot while gradually bringing everything into conformance
by regulating how such uses and structures can be reestablished, repaired
and restored. Additionally, these regulations allow the nonconforming
uses and structures to be physically maintained, and encourage their
upkeep so as to preserve safety, functionality and appearance within
the Town.
