A lawful nonconforming structure existing at
the time of the adoption of or amendment of this code may be continued
although its size or location does not conform to the lot width, lot
area, yard, height, parking and loading and access provisions of this
code; however, it shall not be extended, enlarged, reconstructed,
moved or structurally altered except when required to do so by law
or order or so as to comply with the provisions of this code.
Once a nonconforming use or structure has been
changed to conform, it shall not revert back to a nonconforming use
or structure. Once the Board of Appeals has permitted the substitution
of a more restrictive nonconforming use for an existing nonconforming
use, the substituted use shall lose its status as a legal nonconforming
use and become subject to all the conditions required by the Board
of Appeals.
In the I-1 Industrial District, single-family detached dwellings and their accessory structures may be erected on any legal lot or parcel of record at the time of the adoption of this code. The burden of proof shall be on the applicant for a building permit or certificate of zoning compliance to show that the lot was of record in the County Register of Deeds office prior to the adoption of this code. No further subdivision for residential purposes is permitted in the Industrial District. Any building or structure erected after the adoption of this code under this article shall conform to the requirements of §§
219-66 and
219-68 but shall not be subject to the repair and termination provisions of §
219-65.
