Off-street parking for all uses shall be provided in accordance with the minimum requirements set forth in Table 152.256: Minimum ADA Parking Spaces and § 152.258, Required Off-Street Parking, below. When the computation of required off-street parking spaces results in a fraction of 1/2 or greater, the number of required off-street parking spaces shall be rounded up to the next whole number.
(A) Increase in intensity of use. Additional off-street parking spaces shall be required whenever: a change of use of a building, structure, or lot; or an addition to any unit of measurement specified herein (i.e., dwelling units, gross floor area, seating capacity, number of employees, and the like), results in an increase in the minimum number of required off-street parking spaces to an extent of 15% or more than the number of off-street parking spaces existing on the effective date of this chapter on the single use site, integrated center, or industrial park, as the case may be, whether the total increase occurs at 1 time or in successive stages.
(B) Units of measurements.
(1) Employees. The number of employees shall be compiled based upon the maximum number of persons employed on the premises at any 1 time on an average day or average night, whichever is greater.
(2) Gross floor area. Gross floor area shall be determined per the definition of gross floor area in § 152.426.
(3) Seating capacity/building capacity. Seating or building capacity shall be based upon the determination of the Fire Chief/Building Code regarding maximum building capacity.
(C) Reduction for combined off-street parking areas.
(1) Where an integrated center or industrial park proposes uses with dissimilar peak time parking demands are proposed, an alternate parking plan may be approved in connection with the issuance of an improvement location permit in which a combined off-street parking area is provided. The total number of off-street parking spaces which are developed in a shared off-street parking area may be adjusted as indicated in Table 152.255: Parking Reduction Percentages, below.
(2) The minimum total number of off-street parking spaces to be initially improved under an alternate parking plan shall be the greatest total number of off-street parking spaces calculated under the following scenarios:
Use | Weekday | Weekend | |||
Daytime (6:00 a.m. to 6:00 p.m.) | Evening (6:00 p.m. to midnight) | Daytime (6:00 a.m. to 6:00 p.m.) | Evening (6:00 p.m. to midnight) | Nighttime (Midnight to 6:00 a.m.) | |

100% | 100% | 100% | 100% | 100% |
Parking Reduction Example: Assume an integrated center including an office building, multiple retail uses, and movie theater which, under the basic minimum requirements of this chapter, would be required to provide a total of 225 off-street parking spaces as set forth below.
Parking Reduction Example | ||||||
Basic Minimum | Weekday Daytime | Weekday Evening | Weekend Daytime | Weekend Evening | Weekend Nighttime | |
Office |
50 | 50 | 5 | 5 | 3* | 3* |
Retail |
100 | 60 | 90 | 100 | 70 | 5 |
Theater |
75 | 40 | 75 | 60 | 75 | 8* |
TOTAL |
225 | 150 | 170 | 165 | 148 | 16 |
* Note: Numbers have been rounded up per the requirements of § 152.255. | ||||||
Result: Under an alternate parking plan approval, the minimum total number of off-street parking spaces may be reduced from 225 off-street parking spaces to 170 off-street parking spaces (the reduction alternative which requires the greatest number of off-street parking spaces).
