         2.   Rehabilitation Facilities and Outpatient Physical Therapy Facilities. At least 20% of patient and visitor parking spaces provided to serve rehabilitation facilities and outpatient physical therapy facilities must be accessible.

   17-10-0903 Layout and Design.

      17-10-0903-A Vehicle Spaces. Accessible parking spaces must be either 8 feet in width (minimum) or 11 feet in width (minimum), must be marked to define the width, and must have an adjacent access aisle complying with Section 17-10-0903-B.

      17-10-0903-B Access Aisle. Access aisles serving accessible parking spaces must comply with the following standards:

         1.   Width. The combined width of an accessible parking space and its adjacent access aisle must be 16 feet minimum. Access aisles serving parking spaces that are at least 11 feet wide must be at least 5 feet wide. Access aisles serving parking spaces that are less than 11 feet wide must be at least 8 feet wide. For accessible parking spaces exclusively serving the residents of a residential building that contains no more than 19 dwelling units that are either Type A units or Type B units, however, an aisle width of 5 feet and a combined width of 13 feet is allowed.

         2.   Length. Access aisles must extend the full length of the accessible parking spaces they serve.

         3.   Marking. Access aisles must be marked with diagonal striping so as to discourage parking in them.

         4.   Location. Access aisles may not overlap the vehicular way. Access aisles may be placed on either side of the parking space except for angled parking spaces which must have access aisles located on the passenger side of the parking space.

         5.   Arrangement. Access aisles must adjoin an accessible route. Two parking spaces, other than diagonal parking spaces, may share a common access aisle.

      17-10-0903-C Floor or Ground Surfaces. Parking spaces and access aisles must have surface slopes no steeper than 1:48. Access aisles must be at the same level as the parking spaces they serve. Changes in level are not allowed.

      17-10-0903-D Vertical Clearance.

         1.   Parking spaces for vans and the vehicle routes leading to such spaces must have a vertical clearance of at least 8 feet 2 inches.

         2.   For every 6 or fraction of 6 accessible parking spaces, at least one must provide the vertical clearance required for vans. A van space is not required, however, for parking exclusively serving the residents of a residential building that contains no more than 19 dwelling units that are either Type A units or Type B units.

      17-10-0903-E Signs and Identification. Accessible parking spaces and accessible passenger loading zones must be identified by signs. Such signs must comply with the Chicago Building Code.

      17-10-0903-F Relationship to Accessible Routes. Accessible parking spaces and access aisles must be designed so that vehicles, when parked, cannot obstruct the required clear width of adjacent accessible routes.

      17-10-0903-G Location.

         1.   General. Accessible parking spaces must be located on the shortest accessible route of travel from adjacent parking to an accessible building entrance. In parking facilities that do not serve a particular building, accessible parking spaces must be located on the shortest accessible route to an accessible pedestrian entrance to the parking facility. When buildings have multiple accessible entrances with adjacent parking, accessible parking spaces must be dispersed and located near the accessible entrances.

         2.   Alternatives.

            (a)   In multilevel parking structures, van-accessible parking spaces may be consolidated on a single level.

            (b)   The total number of accessible parking spaces may be distributed among parking facilities if substantially equivalent or greater access and usability to people with disabilities is provided in terms of distance from an accessible entrance or entrances, parking fee and user convenience.

   17-10-0904 Passenger Loading Zones.

      17-10-0904-A Continuous Loading Zones. Where passenger loading zones are provided, one passenger loading zone in every continuous 100 linear feet maximum of loading zone space must be accessible.

      17-10-0904-B Medical Facilities. An accessible passenger loading zone must be provided at an accessible entrance to licensed medical and long-term care facilities where people receive physical or medical treatment or care and when the period of stay exceeds 24 hours. A passenger loading zone must be incorporated at the weather-protected entrance required by Chicago Building Code Section 14B-11-1105.3.

      17-10-0904-C Valet Parking. An accessible passenger loading zone must be provided at valet parking services. If at-grade parking is provided, at least one accessible space for self-parking of a vehicle must be provided.

      17-10-0904-D Mechanical Access Parking Garages. Mechanical access parking garages must provide at least one accessible passenger loading zone at vehicle drop-off and vehicle pick-up areas.

      17-10-0904-E Design.

         1.   Vehicle Pull-up Space Size. Accessible passenger loading zones must provide a vehicular pull-up space that is at least 8 feet in width and at least 20 feet in length.

         2.   Access Aisle. Accessible passenger loading zones must have an adjacent access aisle that complies with the following:

            (a)   Location. Access aisles must adjoin an accessible route. Access aisles may not overlap the vehicular way.

            (b)   Width. Access aisles serving vehicle pull-up spaces must be at least 5 feet in width.

            (c)   Length. Access aisles must be at least 20 feet in length.

            (d)   Marking. Access aisles must be marked so as to discourage parking in them.

         3.   Floor Surfaces. Vehicle pull-up spaces and access aisles serving them must have surface slopes no steeper than 1:48. Access aisles must be at the same level as the vehicle pull-up space they serve.

         4.   Vertical Clearance. A vertical clearance of at least 9 feet 6 inches must be provided at the following locations:

            (a)   Accessible vehicle pull-up spaces;

            (b)   Access aisles serving accessible vehicle pull-up spaces;

            (c)   A vehicular route from an entrance to the accessible passenger loading zone; and

            (d)   A vehicular route from the accessible passenger loading zone to a vehicular exit serving vehicle pull-up spaces.
