C. A lot, land use, structure, or improvement that becomes nonconforming due to a change in zoning district boundary or Development Code regulation, the period prescribed for abatement of the use or improvement of the lot or structure shall begin on the effective date of the change in zoning district boundary or Development Code regulation.

3.01.010: Nonconforming Lots

A. A lot that is not in compliance with the development standards prescribed by this Development Code, as they pertain to minimum area, dimension, or configuration, shall be deemed a "legal nonconforming lot," provided the lot was lawfully created and existing at the time the ordinance codified in this Development Code that created the nonconformity became effective.

B. A legal nonconforming lot shall be granted all development rights and land uses of the zoning district in which it is located.

3.01.015: Nonconforming Land Uses

A use that lawfully occupied a building or land at the time an ordinance codified in this Development Code became effective and does not conform to the use regulations of the zoning district in which it is located, shall be deemed a “legal nonconforming use.” A legal nonconforming use may continue, subject to the following:

A. Discontinuance and Abandonment of Use, and Loss of Legal Nonconforming Status.

1. Without further action by the City, a legal nonconforming use shall lose its legal

nonconforming status and shall not be reestablished if the legal nonconforming use is abandoned for any reason.

a. Residential Land Uses. A legal nonconforming residential land use shall be

deemed abandoned if the use is discontinued for a period of 180 or more consecutive days.

2. Wherein the determination of abandonment of a land use is in question, the

determination of abandonment shall be made by the Zoning Administrator, based upon satisfactory evidence. If there are no business receipts, records, or necessary licenses available to provide evidence that the land use in question has been in continual operation, the Zoning Administrator may make a determination of “abandonment of use” based upon consideration of [i] the removal, without replacement, of equipment, furniture, machinery, fixtures, structures, or other components necessary to business operation, and/or [ii] the shut-off or disconnect of utilities (water, electricity, and/or natural gas).

3. Following the discontinuance of a nonconforming land use, the use of a property

shall comply with all current requirements of this Development Code and the applicable zoning district.

Division 3.02—Nonconforming Signs

total cost of the reconstruction does not exceed more than 50 percent of the sign’s fair market value prior to the damage or destruction. The reconstruction, restoration, or rebuilding of a damaged or destroyed legal nonconforming sign shall commence within 6 months following the occurrence of the damage or destruction, unless extended by the Zoning Administrator, and shall be diligently pursued to completion.

B. In the event that the cost of reconstructing, restoring, or rebuilding a sign exceeds 50 percent of the fair market value of the sign prior to any damage occurring, the sign may be reconstructed, restored, or rebuilt up to its original size, design and placement, and the use of the sign may be resumed, subject to the following:

1. The Planning Commission, at a duly noticed public hearing, must find that [i] the

reconstruction, restoration, or rebuilding of the nonconforming sign will not be detrimental or injurious to the health, safety or general welfare of persons residing or working in the neighborhood, and will not be detrimental or injurious to property and improvements in the neighborhood, and [ii] continuation of the nonconforming sign will not result in an annoyance to and/or reduction of any surrounding property.

2. In considering whether a nonconforming sign results in annoyance to and/or

reduction of any surrounding property, the Zoning Administrator shall consider the following:

a. The number of additional nonconforming signs on the property;

b. Whether the nonconforming sign(s) impede visibility toward other

conforming signs on the subject property and/or adjacent properties;

c. The extent to which the nonconforming sign(s) contribute to sign clutter

within the surrounding area; and

d. The extent to which such nonconforming sign(s) provide the subject

property, or use thereon, with its only means of identification.

3. The reconstruction, restoration, or rebuilding of a nonconforming sign shall be

completed within 6 months following building permit issuance, unless extended by the Zoning Administrator, and shall be diligently pursued to completion.

4. Nothing in this Division shall be construed to permit the continuation of conditions

that will endanger the public health, safety or welfare, or which constitute a public or private nuisance.

3.02.015: Illegal Signs

a. An abandoned sign is a sign remaining in place for a period of 90 or more

consecutive days, which no longer advertises or identifies an ongoing business, product, or service available on the premise where upon the sign is located.

b. When the abandonment of a sign is in question, the determination shall be

made by the Zoning Administrator, based upon satisfactory evidence. When there are no business receipts, records or necessary licenses available to provide evidence that the business for which the sign was erected has been in continual operation, the Zoning Administrator may make a determination of sign abandonment based upon [i] consideration of the removal, without replacement, of equipment, furniture, machinery, fixtures, structures, or other components necessary to business operation, and/or [ii] the shut-off or disconnect of utilities (water, electricity, and/or natural gas).

3. Unmaintained Signs. An unmaintained sign is a sign that has not been kept in a

proper state of preservation, free of damaged or broken components, and has been kept neatly painted and maintained.

4. Illegally Erected Signs. A sign is illegally erected if:

a. It violates any provision of this title, except as provided by Paragraph B.2 of

this Section;

b. It was erected without first obtaining required permits; or

c. It was erected without complying with all ordinances and regulations in

effect at its time of construction, erection or use. No sign that has been erected in violation of any previously existing sign regulation(s) shall become a conforming sign by virtue of the adoption of any new regulation(s).

B. Existing Illegal Signs. Any business located on the same property where a sign has been determined by the Zoning Administrator to be illegal, shall not be granted a permit for additional signs until all illegal signs have been removed, except as follows:

1. The sign determined to be illegal is associated with a business that is different from

the business seeking a permit for new signage, even though they may be located in the same center or complex; or

  1. The sign determined to be illegal is not owned or controlled by the permit

applicant, and the permit applicant is not the agent of the person who owns or controls the illegal sign.

C. Identification and Inventory of Illegal Signs. Within one-year following the enactment date of this Section, the City shall commence with the identification and inventory of illegal signs within the City. Upon completion of the identification and inventory of illegal signs, the City may commence abatement of all illegal signs identified in the sign inventory.

A. Amortization of Nonconforming Signs. A sign lawfully placed, erected, or constructed at the time an ordinance codified in this Development Code became effective, and which does not conform to the applicable current sign regulations, is deemed a "legal nonconforming sign." The classifications of legal nonconforming signs identified in Table 3.02-1 (Amortization Period of Certain Classifications of Nonconforming Signs), below, shall be removed or made to meet the current requirements of this Division within the timeframes specified by said Table, except that timeframes for signs nonconforming by reason of annexation to the City shall begin on the date of completion of the annexation.
