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-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-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.
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)
The following rules apply when calculating off-street parking requirements.
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)
17-10-0402 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-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.
17-10-0404 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.
17-10-0406 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)
17-10-0501 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
17-10-0503 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.

17-10-0601-C Required off-street parking and non-required accessory parking serving nonresidential uses in RS districts (e.g., religious assembly) must be located on the same zoning lot as the use served, except that such parking may be located off site if approved as a special use. In such cases, the distance between the nearest parking space and the entrance to the use served by such parking may not exceed 600 feet. (See the special use procedures of Sec. 17-13-0900)
17-10-0602-C Required off-street parking and non-required accessory parking serving uses other than detached houses, townhouses and two-flats in RT, RM and DR districts must be located on the same zoning lot as the use served, except that such parking may be located off site if approved as a special use. In such cases, the distance between the nearest parking space and the entrance to the use served by such parking may not exceed 600 feet. Off-site parking spaces accessory to a use in an RT, RM or DR district may not be located in RS1, RS2 or RS3 district. (See the special use procedures of Sec. 17-13-0900)
1. Required accessory parking serving nonresidential uses in B, C, DC, DX, DS and M districts may be located off site when approved as an administrative adjustment (See Sec. 17-13-1003-FF), provided that:
(a) the distance between the nearest off-site, accessory parking space and the entrance to the use served by such parking does not exceed 100 feet; and
(b) the proposed off-site, accessory parking is not located in an R or DR district.
2. Required accessory parking serving residential or nonresidential uses in B, C, DC, DX, DS and M districts may be located off site when approved as a special use (See Sec. 17-13-0900), provided that the distance between the nearest off-site, accessory parking space and the entrance to the use served by such parking does not exceed 600 feet.
17-10-0604 Agreement. An agreement providing for the use of off-site parking, executed by the parties involved, must be filed with the Zoning Administrator, in a form approved by the Zoning Administrator. Off-site parking privileges will continue in effect only as long as the agreement, binding on all parties, remains in force. Agreements must guarantee long-term availability of the parking, commensurate with the use served by the parking. If the agreement is no longer in force, then parking must be provided as otherwise required by this chapter.

17-10-0801 Description. Cooperative parking represents an arrangement in which two or more commercial uses provide their required off-street parking in the same parking lot, thereby reducing the number of individual parking lots and the number of curb cuts required to serve such lots. Reduced off-street parking requirements are available as an incentive for providing cooperative parking. Approval of an administrative adjustment is required. (See Sec. 17-13-1003-HH.)
17-10-0803 Location of Cooperative Parking Facility. A use for which an application is being made for cooperative parking must be located within 600 feet walking distance of the cooperative parking, measured from the entrance of the use to the nearest parking space within the cooperative parking lot.
