1. Building Expansion. A legal nonconforming building shall be permitted to expand in area and height as long as the nonconformity is not increased and the expansion otherwise meets the current Unified Development Code. For example, if a building is in violation of the maximum height standard, it can be expanded in area as long as the new addition does not exceed the maximum height standard and is otherwise in compliance with current Unified Development Code.

2. Building Exterior Alteration. The exterior walls of a building shall not be moved except as provided in the previous clause. Otherwise, the roof and exterior walls may be maintained, repaired, re-faced, and modified, resulting in the original aesthetic character or an altered exterior character, as long as the building’s nonconformity is not increased and the alteration otherwise meets the current Unified Development Code.

3. Building Interior Alteration. Ordinary repair and replacement of interior finishes, heating systems, fixtures, electrical systems, or plumbing systems; and interior wall modifications are not regulated by the Unified Development Code.

4. Building Relocating. A legal nonconforming building may be relocated if, by moving the building, it decreases the legal nonconformity and the relocation otherwise meets the current Unified Development Code.

1. Structure Alteration. A legal nonconforming structure shall be permitted to be altered in height, area, mass, and time as long as the nonconformity is not increased and the alteration otherwise meets the current Unified Development Code. For example, if a permanent sign is in violation of the maximum height standard, it can be altered as long as the alteration does not exceed the maximum height standard currently permitted and is otherwise in compliance with Unified Development Code.

2. Structure Relocating. A legal nonconforming structure may be relocated if, by moving the structure, it decreases the legal nonconformity and the relocation otherwise meets the current Unified Development Code.

3. Conversion for Longevity. Converting a structural component of a legal nonconforming structure to a more permanent material in order to prolong legal nonconformity shall not be permitted. For example, a legal nonconforming permanent pole sign would not be permitted to replace its existing wood posts with metal posts even if dimensionally the same size.

1. Condemned Structures. If a structure, through lack of maintenance, is declared by an authorized official to be condemned due to its physical or unsafe condition, it shall lose its legal nonconforming status and become illegal nonconforming unless the structure is restored or repaired within three (3) months of the declaration. The Zoning Administrator may grant an appropriate extension of time if work was started within the initial three (3) month period and reasonable attempts are being made by the owner to remedy the condemnation.

2. Removal of Permanent Structures. If a permanent structure is fully or significantly removed or razed (e.g., eighty percent (80%) or more of the structure), the remaining permanent structure shall lose its legal nonconforming status and become illegal nonconforming; unless by significantly removing or razing the permanent structure the remaining permanent structure is in compliance or more in compliance with the current Unified Development Code.

3. Removal of Temporary Structures. If a temporary structure is removed (e.g., moved inside, taken off-site, or replaced by a new temporary structure), the temporary structure shall lose its legal nonconforming status and become illegal nonconforming.

4. Flood. If a structure is severely damaged from a flood, resulting in a loss of either fifty percent (50%) of its market value or fifty percent (50%) of its structure, all reconstruction shall be required to meet the current Unified Development Code. All other flood damaged structures shall be allowed to rebuild the structure that previously existed.

5. Acts of Nature. If a structure is severely damaged from an act of nature, excluding flooding, resulting in a loss of either seventy percent (70%) of its market value or seventy percent (70%) of its structure, all reconstruction shall be required to meet the current Unified Development Code. All other structures damaged by an act of nature shall be allowed to rebuild the structure that previously existed.
