When you must provide off-street parking

(a) Determining if parking is required, and the appropriate parking ratio. No off-street parking is required in the Primary Urban Center Development Plan area and Ewa Development Plan area, except for those areas thereof located in the residential, agricultural, and preservation zoning districts. Additionally, no off-street parking is required in any zoning district within 0.5 miles of an existing or future Honolulu rail transit station, as identified in the accepted environmental impact statement, or in the transit-oriented development special districts. The minimum off-street parking ratios shown below in Table 21-6.1 apply to all other areas not identified in this subsection. In areas where no parking is required, any parking that is provided must meet the design, dimensions, and other standards set forth in this chapter.

(2) When a building or premises includes uses incidental or accessory to a principal use, the total number of required parking spaces will be determined on the basis of the parking requirements of the principal use. Floor area that may be eliminated for purposes of calculating parking requirements includes: (A) Common areas and accessory recreation areas in multi-unit dwellings, lodging, small or large group living, and consulates; (B) Accessory areas in assembly, education, government, or other similar uses, except all classrooms, offices, and gallery space; (C) Stairwells and ancillary spaces, when directly and exclusively used for mechanical spaces and not actively used by employees. Mechanical car-wash areas are included in this exemption; and (D) Other areas that do not induce a parking demand, as determined by the director.
