17-10-0200 Off-street parking ratios.

   17-10-0201 General. Off-street parking spaces must be provided in accordance with the off-street parking schedules of this section.

   17-10-0202 Parking Groups. Each land use listed in the use tables of Sec. 17-2-0200, Sec. 17-3-0200, Sec. 17-4-0200 and Sec. 17-5-0200, is assigned to a parking group which, in turn, establishes the applicable off-street parking standard for the listed use type. The off-street parking standards that apply to each of the parking groups are listed in the off-street parking schedules of this section.

   17-10-0203 Districts. Many parking standards vary according to the district in which the use is located. The first column of the off-street parking schedules identifies the zoning districts in which the listed standard applies.

   17-10-0204 Minimum Automobile Parking Ratio. The second column of the off-street parking schedules establishes the minimum required off-street automobile parking ratio.

   17-10-0205 Maximum Accessory Parking Ratio. In downtown zoning districts, many uses are subject to a maximum accessory parking ratio. The third column of off-street parking schedule 2 establishes applicable maximum accessory parking ratios. When the number of off-street spaces provided exceeds the stated maximum accessory parking ratio, then each parking space provided in excess of the maximum accessory ratio will be counted as 350 square feet of floor area when calculating the building's floor area and determining compliance with applicable floor area ratio standards. Parking spaces provided in excess of maximum accessory ratios will not be counted as floor area if such spaces are located underground, below the lowest grade level of any abutting street.

   17-10-0206 Minimum Bicycle Parking. The final column of the off-street parking schedules establishes the minimum bicycle parking ratio for the parking group.

   17-10-0207 Off-Street Parking Schedule 1: Neighborhood Zoning Districts. Schedule "1" presents off-street parking standards for uses in neighborhood zoning districts (i.e., R, B, C and M districts). The off- street parking standards for downtown (D) zoning districts are presented in Sec. 17-10-0208 below. In the event of conflict between this schedule and zoning district use regulations (e.g., this schedule establishes a parking standard for a use not allowed in the underlying zoning district), the zoning district use regulations govern.

17-10-0300 Bicycle parking.

   17-10-0301 Spaces Required. Except as expressly stated in Section 17-10-0301-B, bicycle parking must be provided in accordance with the off-street parking ratios of Section 17-10-0200.

      17-10-0301-A Unless otherwise expressly stated, whenever bicycle parking is required, at least 2 bicycle spaces must be provided.

      17-10-0301-B No use is required to provide more than 50 bicycle parking spaces.

      17-10-0301-C The Zoning Administrator is authorized to approve an administrative adjustment reducing the number of bicycle spaces required for a particular use in accordance with Sec. 17-13-1003-GG.

   17-10-0302 Design and Location.

      17-10-0302-A Required bicycle parking spaces for nonresidential uses must have minimum dimensions of 2 feet in width by 6 feet in length, with a minimum overhead vertical clearance of 7 feet. Racks and other fixtures used to provide required bicycle parking for nonresidential uses must be of a design that is approved by the Chicago Department of Transportation. Such fixtures must be affixed securely to the ground or a building, to which a bicycle may be locked or chained. Bicycle racks are not required for bicycle parking associated with residential uses. Required bicycle parking for residential uses may be provided in garages, storage rooms and other resident-accessible, secure areas.

      17-10-0302-B Required bicycle parking may be located indoors or outdoors. Such spaces must be located on private property unless the Commissioner of the Department of Transportation approves location within the public right-of-way. If required bicycle parking facilities are not visible from the street, signs must be posted indicating their location.

      17-10-0302-C A nonresidential use may use up to two vehicle parking spaces required under this Chapter as space for providing bicycle parking.

      17-10-0302-D Space within dwelling units or on balconies may not be counted toward satisfying bicycle parking requirements.

      17-10-0302-E Areas used for required bicycle parking must be:

         1.   paved and drained to be reasonably free of mud, dust, and standing water; and

         2.   well-lighted.

   17-10-0303 Non-accessory Parking. A non-accessory parking facility must provide bicycle parking area equivalent to 2 parking spaces if the facility has more than 250 parking spaces. The space must contain lockers, hard covers or shells, or other similar structures or devices in which bicycles may be individually covered and locked.

(Added Coun. J. 5-26-04, p. 25275; Amend Coun. J. 11-8-12, p. 38872, § 251; Amend Coun. J. 9-11-13, p. 60173, § 11; Amend Coun. J. 7-20-22, p. 50878, § 6)

17-10-0400 Calculation rules.

   The following rules apply when calculating off-street parking requirements.

   17-10-0401 Multiple Uses.

      17-10-0401-A Unless otherwise approved, lots containing more than one principal use must provide parking in an amount equal to the total of the requirements for all principal uses. (See the shared and cooperative parking provisions of Sec. 17-10-0600 and Sec. 17-10-0800 for possible exceptions)

      17-10-0401-B When two or more principal uses are located on a single lot and the applicable parking ratio for such uses exempts a certain portion of the floor area (e.g., the first 4,000 or 10,000 square feet), only one such floor area exemption may be taken.

      17-10-0401-C No parking is required for accessory uses unless otherwise expressly stated.

   17-10-0402 Fractions. When measurements of the number of required spaces result in a fractional number, any fractional result of 0.5 or more must be rounded up to the next consecutive whole number. Any fractional result of less than 0.5 may be rounded down to the previous consecutive whole number. For example, if a minimum ratio of 2 spaces per 1,000 square feet is applied to a use with 1,900 square feet of floor area, the result (3.8) must be rounded up to 4 spaces.

   17-10-0403 Area Measurements.

      17-10-0403-A Unless otherwise expressly stated, all area-based (square feet) parking standards must be computed on the basis of gross floor area, which is to be measured as the sum of the gross horizontal area devoted to such use, including accessory storage areas located within sales or working spaces, such as counters, racks, or closets and any basement floor area devoted to retailing activities, to the production or processing of goods, or to business or professional offices. Except as noted in the preceding sentence, "floor area" for purposes of calculating off- street parking requirements does not include: floor area devoted primarily to storage purposes; floor area devoted to off-street parking or loading facilities, including aisles, ramps, and maneuvering space; or basement floor area.

      17-10-0403-B For outdoor areas, calculations will be based on the portion of the lot actually being used for the specified purpose.

      17-10-0403-C When open land is used for manufacturing, storage, or other operations in a manner similar to indoor operations, such open use of land must be added to floor space in determining the number of off-street parking spaces required

   17-10-0404 Occupancy- or Capacity-Based Standards. For the purpose of calculating parking requirements based on employees, students, or occupants, calculations are to be based on the greatest number of persons working on any single shift, the maximum enrollment or the maximum fire-rated capacity, whichever is applicable and whichever results in the greater number of spaces.

   17-10-0405 Bench Seating. When seating consists of benches, pews or other similar seating facilities, each 20 linear inches of seating space counts as 1 seat.

   17-10-0406 Unlisted Uses. Upon receiving a permit or development application for a use not specifically addressed, the Zoning Administrator is authorized to apply the off-street parking standard specified for the use that the Zoning Administrator deems most similar to the proposed use or require the applicant to submit a parking study or other evidence that will help Zoning Administrator determine the appropriate parking ratio to be applied.

   17-10-0407 Public Places of Amusement. There is no special parking requirement for uses that require a public place of amusement (PPA) license. Parking requirements are to be determined solely in accordance with the off-street parking schedules of Sec. 17-10-0200.

(Added Coun. J. 5-26-04, p. 25275; Amend Coun. J. 3-9-05, p. 44391)

17-10-0500 Use of off-street parking areas; leasing of required.

   17-10-0501 Required off-street parking areas are to be used solely for the parking of licensed motor vehicles in operating condition. Required spaces may not be used for the display of goods for sale or lease or for long- term storage of vehicles, boats, or recreational vehicles or building materials.

   17-10-0502 Required off-street parking spaces are intended to serve residents, tenants, patrons, employees, or guests of the principal use. Off-street parking spaces that are required by this Zoning Ordinance must be maintained for the life of the principal use. Except as expressly allowed by Sec. 17-10-0503, the following are deemed non-accessory parking spaces and may not be counted toward satisfaction of minimum off-street parking requirements:

      17-10-0502-A spaces that have been sold to or are owned by persons or entities who do not at the same time also own a dwelling unit used as a residence or other permitted principal use, unless the parking space is rented to or is otherwise being used by residents, tenants, patrons, employees or guests of the principal use; and

      17-10-0502-B Spaces used by persons who are not residents, tenants, patrons, employees or guests of the principal use.

   17-10-0503 In RM5, RM5.5, RM6, RM6.5, all B and all C districts, and DR dash 3 and DX dash 3 districts, up to 25% of the number of parking spaces required for residential uses may be leased out on a daily, weekly or monthly basis to persons who are not residents, tenants, patrons, employees, or guests of the principal use. In the RM6, RM6.5, B dash 5 and C dash 5 districts, and DR dash 5 and DX dash 5 districts and above, the amount of spaces allowed to be leased out to non-occupants may be increased to 45% if reviewed and approved as a special use in accordance with Sec. 17-13-0900.

   17-10-0504 Before a parking garage operator may obtain a license for a public (non-accessory) or accessory garage, the applicant must provide the Zoning Administrator with a written statement declaring that the minimum off-street parking standards for the zoning lot have been satisfied, and that all of the non-accessory parking spaces to be licensed are spaces provided in excess of applicable minimum standards.

   17-10-0505 No motor vehicle repair work of any kind is permitted in conjunction with accessory parking facilities located in R, B, DC, DX and DR districts.

   17-10-0506 No motor vehicle repair work of any kind is permitted in conjunction with open (outdoor) accessory parking facilities located in C districts.

   17-10-0507 No motor vehicle repair work of any kind is permitted in conjunction with open (outdoor) accessory parking facilities located in M districts if such parking facilities are located within 500 feet of a residential or B district.

   17-10-0508 In D districts, parking spaces in non-accessory parking facilities may not be used for temporary storage containers.

(Added Coun. J. 5-26-04, p. 25275; Amend Coun. J. 9-13-06, p. 84870, § 2; Amend Coun. J. 6-25-14, p. 84153, § 1)

17-10-0600 Location of off-street parking.

   17-10-0601 RS Districts. The following standards apply in all RS districts.
