In computing the number of parking spaces required, the following rules govern:
   (A)   Service areas such as mechanical rooms, attics, and closets are excluded from the calculation of floor area for determining required parking spaces.
   (B)   Where fractional spaces result in computing required parking spaces, the required number of spaces must be increased to the nearest whole number.
   (C)   The parking space requirements for a use not specifically listed shall be the same as those for the most similar to the proposed use, as determined by the Building Official.
   (D)   Whenever a building or use constructed or established after the effective date of this chapter is changed or enlarged in floor area, number of employees, number of dwelling units, seating capacity or otherwise, to create a need for an increase of 10% or more in the number of existing parking spaces, such spaces shall be provided on the basis of the enlargement or change. Whenever a building or use existing prior to the effective date of this chapter is enlarged to the extent of 50% or more in floor area or in the area used, said building or use shall then and thereafter comply with the parking requirements set forth herein.
   (E)   In the case of mixed uses, the parking spaces required shall equal the sum of the requirements of the various uses computed separately.
   (F)   Where requirements are established on the basis of the number of seats, such requirements shall be based on the seating capacity permitted by the building and/or fire code and approved by the city's Building and Fire Officials. When determining seating capacity for a building, use, or structure utilizing bench seating, each 22 inches of bench shall be considered one seat.
   (G)   Where a manufacturing/industrial use has more than one working shift of employees, parking facilities shall be adequate to accommodate overlap requirements during transition periods.
   (H)   When the developer of a large-scale development can demonstrate that such development will require fewer parking spaces than required by the standards of this chapter, the Building Official may permit a reduction in the number of required parking spaces for the development. Such a reduction in parking spaces shall be justified through the development of a parking study prepared by a professional traffic engineer or transportation planner and submitted to the Building Official. The balance of the land necessary to meet these requirements shall be held in reserve as an undeveloped area, to meet any future needs generated by an expansion of the business, a change in land use, or underestimated parking demand.
