The lawful use of any building or land lawfully existing at
the time of the enactment of this Part 4 or any amendment thereto
may be continued although such use does not conform to the provisions
of this Part 4 as a result of such enactment or amendment.
Any structure or portion thereof declared unsafe by a proper
authority may be restored to a safe condition.
A nonconforming building may not be reconstructed or structurally
altered during its life to an extent exceeding in aggregate cost 50%
of the assessed value of the building, unless said building is changed
to a conforming use.
A nonconforming use shall not be extended, but the extension
of a lawful use to any portion of a nonconforming building which existed
prior to the enactment of this Part 4 shall not be deemed the extension
of such nonconforming use.
Nothing herein contained shall require any change in plans,
construction or designated use of a building for which a building
permit has heretofore been issued and the construction of which shall
have been diligently prosecuted within three months of the date of
such permit and the ground-story framework of which, including the
second tier of beams, shall have been completed within six months
of the date of the permit and which entire building shall be completed
according to such plans as filed within a year from the date of this
Part 4.
No building damaged by fire or other cause to the extent of
more than 65% of its assessed value shall be repaired or rebuilt,
except in conformity with the regulations of this Part 4. No lot shall
be reduced in area that any required open space will be smaller than
prescribed in the regulations for the district in which said lot is
located. Whenever such reduction in lot area occurs, any building
located on said lot shall not thereafter be used until such building
is altered, reconstructed or relocated so as to comply with the area
and yard requirements applicable thereto.
Any nonconforming building or use which has been changed to
a conforming use shall not be changed back again to a nonconforming
use.
A nonconforming use shall be considered to be abandoned if there
occurs a cessation of the previous use or activity on the part of
the owner or tenant for a period of six months from the date of cessation
of use or activity.
