7.4.4.   Expansion of Buildings or Structures
If a building permit is required for expansion of the building or structure, the expansion shall require correction of existing on-site nonconforming off-street parking, landscaping, screening, wall or fencing, and exterior lighting in accordance with this section.
   A.   25 Percent or less of Structure Value. Expansions in any continuous one-year period that costs 25 percent or less of the current assessed value of the structure shall not require any correction to nonconforming site aspects.
   B.   More than 25 Percent but less than 75 Percent of Structure Value. Expansions in any continuous one-year period that costs more than 25 percent but less than 75 percent of the current assessed value of the structure shall require that a corresponding percentage of the off-street parking, landscaping, screening, wall or fencing, and exterior lighting standards of this Ordinance be installed or upgraded on the site, until the site achieves 100 percent compliance. Example: A hypothetical building is required to provide at least 40 off-street parking spaces, but the building site only includes 20 spaces. If the building is remodeled such that the cost of remodeling equals 30 percent of the building's assessed value, the remodeling project must add 12 parking spaces (30% x 40 required spaces). This increases the development's degree of compliance with off-street parking standards from 50 percent (20 of 40 required spaces) to 80 percent (32 of 40 required spaces).
   C.   75 Percent or More of Structure Value. Expansion projects that cost 75 percent or more of the current assessed value of the structure shall require 100 percent compliance with the off-street parking, landscaping, screening, wall or fencing, and exterior lighting standards of this Ordinance.
   D.   Two or Fewer Additional Parking Spaces. When two or fewer additional off-street parking spaces are required under this subsection as a result of an expansion project, such additional off-street parking is not required to be installed, but the applicant may install a comparable number of bicycle parking spaces.
   E.   Addition of Outdoor Storage Area Only. When only outdoor operations/storage/display areas are being added or increased on a site, the percentage increase in outdoor operations area shall require a corresponding percentage increase in perimeter buffers and screening. Perimeter buffer and screening augmentation shall be located so as to achieve the performance objectives in Section 5.6, Landscaping, with priority given to screening the impacts of outdoor operations.
