Any nonconforming structure or use lawfully existing at the time of enactment of this chapter or any subsequent amendment may be continued under the following conditions:
A. 
A nonconforming use shall terminate upon abandonment at any time, which shall be presumed when the actual conduct of a nonconforming use is discontinued for a period of 12 consecutive months for any reason. The structure or premises or structure and premises in combination, as the case may be, shall not thereafter be used except in conformance with the regulations of the district in which it is located.
B. 
A nonconforming use shall not be enlarged, extended, moved to a different position on the lot or structurally altered in any way except as may be required for normal maintenance or to modernize or redecorate existing bath, kitchen, utility or living areas or to prevent damage or injury. A preexisting nonconforming use in a structure may be changed to a use permitted in the district in which it is located. All renovations must be within the existing footprint of the building.
C. 
A nonconforming structure shall not be enlarged or altered in a way which increases its nonconformity and shall not be moved any distance whatever unless it will thereafter conform to the regulations of the district in which it is located.
D. 
A nonconforming structure or use may be restored or reconstructed if damaged or destroyed by fire or other accidental cause, subject to the limitations of Subsections A, B and C above.
E. 
Any structure or premises or structure and premises in combination in or on which a nonconforming structure or use is superseded by a permitted structure or use shall thereafter conform to the regulations of the district in which it is located, and the nonconforming structure or use shall not thereafter be reinstituted.
F. 
The Municipal Zoning Officer and Municipal Building Official shall be permitted to administratively approve, through the issuance of a zoning permit and building permit, the equal replacement in square footage of existing concrete or solid brick patios and walkways, with grass paving units, provided that the following conditions are met:
[Added 8-22-2009 by Ord. No. 2009-28]
(1) 
All work is within the current footprint of the patio or walkway and there is no expansion beyond those areas.
(2) 
The grass paving units are installed in accordance with the grass paving units manufacturer's specifications.
(3) 
There is no surface grade changes unless approved by the Zoning Official to assure improved drainage runoff or lessen runoff onto an adjacent property.
(4) 
The applicant shall provide both an existing and as-built survey to assure compliance.
G. 
No permit shall be issued for the demolition of any principal structure that contains an existing nonconforming accessory structure on the same lot unless the Combined Planning/Zoning Board has approved the continuance of the nonconforming accessory structure by resolution. The mere submission of an application to the Board shall not constitute satisfaction of this condition.
