The provisions of this section shall apply to buildings, structures,
signs, lands and uses which become nonconforming as the result of
the application of this chapter, as amended, to the property on which
they are located or from reclassification of the property under any
subsequent amendments to this chapter.
Where a structure existed on a property at the effective date
of this chapter or any amendment to it affecting the property and
does not conform to the requirements of this chapter or amendment
regarding height, setbacks from street or lot lines, lot coverage,
etc., such structure may remain, subject to the following provisions:
A. No structure shall be enlarged or altered so that its height or proximity
to property lines creates a nonconformity or increases an existing
setback or height nonconformity.
B. Replacement of a nonconforming structure shall be done with respect
to the setback and height requirements for the zoning district wherein
the property is located. Where the owner alleges a hardship, he may
appeal to the Zoning Hearing Board to grant approval of replacement
of the foundation of the building proposed to be replaced. In no case
shall the replacement make more nonconforming the original nonconforming
structure.
