[Amended by Ord. No. 1988-21]
A. Alterations, as applied to a nonconforming structure, shall only
include a change or rearrangement in the structural supports or a
change in the exterior appearance of a structure.
B. A nonconforming structure may be altered, provided that the cost
of alterations does not exceed, in the aggregate, 50% of the assessed
value of the structure as recorded in the records of the Tax Assessor.
More substantial alterations are not permitted unless the structure
is changed to conform to the requirements of this chapter.
C. A nonconforming structure may not be enlarged, extended, increased
in height, width or depth, moved or relocated, modified in such a
way so as to increase habitable or usable space, number of dwelling
units or number of bedrooms, unless such structure is changed to a
structure conforming to the requirements of this chapter, except that
an existing one- or two-family structure (principal or accessory)
may be enlarged, extended or added to, provided:
(1) The structure is located on a lot which conforms to minimum lot area
requirements; and
(2) The enlargement, extension or addition conforms to all yard requirements;
or
(3) The portion of the enlargement, extension or addition which does
not conform to yard requirements consists entirely of the enclosure
of existing side or rear porches; or
(4) The portion of the enlargement, extension or addition which does
not conform to yard requirements is located entirely to the rear of
the existing nonconforming structure, has a side yard setback not
less than the existing nonconforming structure and conforms to all
other bulk requirements.
D. Accessory structures may not be constructed on nonconforming lots
and/or on lots which contain a nonconforming principal structure unless:
(1) The lot conforms to minimum lot area requirements.
(2) A single- or two-family principal residential building exists on
the lot.
(3) The new accessory structure conforms to all requirements of this
chapter for accessory buildings and uses.
Nothing herein contained shall require any change in the plans,
construction or designated use of a building for which a building
permit has been heretofore issued and substantial construction has
taken place prior to the date of the adoption of this chapter.
Whenever the boundaries of a district shall be changed so as
to transfer an area from one district to another district of a different
classification, the provisions of this chapter shall also apply to
any nonconforming uses existing therein or created thereby.
