Nonconforming Structures
A.
Improvement, Alteration or Expansion of a Structure. A legally established nonconforming structure shall
be permitted provided that the nonconforming structure shall not be improved, altered or expanded except
to meet safety requirements or conform to the requirements of this Chapter. Where the improvement or
expansion is to a residential structure, such improvement or expansion may occur provided that no
additional dwelling units result, and that the improvement or expansion complies with the requirements for
residential structures of the applicable district. 
B.
Maintenance, Alteration or Remodeling of a Structure. Maintenance, alteration or remodeling of a
structure, as required by any public law and so ordered by a public officer in authority, shall be permitted.
Routine maintenance shall be permitted where no expansion of the nonconformity occurs as a result of the
maintenance.
C.
Repair/Reconstruction of Damaged Structure (Other than Signs). Where a nonconforming structure has
been damaged by fire, wind, flood or other natural causes, it may be repaired/reconstructed provided that
repairs/reconstruction are:
(1)
Initiated within six (6) months and completed within one (1) year of the damage (An extension
(for a period of up to 12 months) may be granted by the Zoning Administrator provided he/she
determines that the structure does not pose a public health and safety risk).
(2)
Not resulting in any increase in structural dimension except as otherwise permitted in this Article; 
(3)
Not resulting in any change in location of the structures except to provide greater conformance
with the requirements of this Chapter; and,
(4)

with the provisions of this Chapter.
