If an automotive lift(s) is expressly approved as part of a planned development, the automotive lift(s) shall be exempt from the standards of this Section 17-10-1010.

         2.   Automotive lifts shall be exempt from the following requirements of this code:

            (a)   the parking lot dimensions requirements of Section 17-10-1001;

            (b)   the parking lot surfacing requirements of Section 17-10-1002;

            (c)   the vertical clearance requirements of Section 17-10-1003;

            (d)   the striping requirements of Section 17-10-1005; and

            (e)   the maximum parking requirements of Sections 17-10-0205 and 17-10-0208 as they relate to the additional parking spaces provided by the use of automotive lifts.

         3.   Allowed automotive lifts shall be located wholly within an enclosed building and shall not be visible from outside the building or facility. For purposes of this item (3), an enclosed building shall include a parking facility as defined in Chapter 14B-2.

      17-10-1010-B Use In Residential Buildings/Residential Use In Mixed-Use Buildings.

         1.   Automotive lifts in residential buildings shall be used only for accessory parking in excess of minimum off-street parking ratios and for any non-accessory parking permitted in the building. Automotive lifts in residential buildings shall not be used to satisfy minimum off-street parking ratios.

         2.   Allowed automotive lifts within residential buildings shall be operated by a valet or an attendant employed by the Equipment's owner or owned and operated by an owner or resident of a dwelling unit within the building.

      17-10-1010-C Use In Non-Residential Buildings/Non-Residential Use In Mixed-Use Buildings.

         3.   Allowed automotive lifts within non-residential buildings shall be operated by a valet or an attendant employed by the Equipment's owner.

   17-10-1011 Electric Vehicle Supply Equipment. This section shall apply to building permit applications for a new construction building project that includes accessory parking or non-accessory parking as described in this section.

      17-10-1011-A Residential Buildings.

         1.   Where the first building permit application for the project is submitted after October 31, 2020, and before November 1, 2023, new construction of a multi-unit residential building containing five or more dwelling units where on-site parking is provided shall include equipment so that at least 20 percent, and no less than one, of the parking spaces are either EVSE-ready spaces or EVSE-installed spaces.

         2.   Where the first building permit application for the project is submitted on or after November 1, 2023, new construction of a residential building intended for household living with accessory parking provided shall include equipment so that 100 percent of the accessory parking spaces serving dwelling units, 20 percent of the accessory parking spaces serving other than dwelling units, and 20 percent of the non-accessory parking spaces are either EVSE-ready spaces or EVSE-installed spaces.

         3.   Where the first building permit application for the project is submitted on or after November 1, 2023, new construction of a residential building intended for group living or lodging with accessory parking provided shall include equipment so that 20 percent of parking spaces are either EVSE-ready spaces or EVSE-installed spaces.

      17-10-1011-B Nonresidential Buildings. Where the first building permit application for the project is submitted after October 31, 2020, new construction of a building other than a residential building, with 30 or more parking spaces provided shall include equipment so that at least 20 percent of the parking spaces are either EVSE-ready spaces or EVSE-installed spaces.

      17-10-1011-C Accessible EVSE-Ready Spaces and EVSE-Installed Spaces. Installation of EVSE-ready spaces or EVSE-installed spaces shall neither increase nor reduce the number, layout, or design of accessible parking spaces required by Chapter 17-10-0900 or 14B-11 of the Municipal Code of Chicago, and any accessible EVSE-ready space or EVSE-installed space shall also be available for use by an automobile that is not an electric vehicle provided such automobile bears an appropriate handicapped parking decal or device. If this section requires the installation of EVSE-ready spaces or EVSE-installed spaces, then the number of accessible parking spaces required by Chapter 17-10-0900 or 14B-11 of the Municipal Code of Chicago that must also be EVSE-ready spaces or EVSE-installed spaces is as follows:

 

Total EVSE-Ready Spaces or EVSE-Installed Spaces	Minimum Number of EVSE-Ready Spaces or EVSE-Installed Spaces Required to Be Accessible Parking Spaces
1 to 50	1*
51 to 75	2
76 to 100	3
More than 100	3, plus 1 for every 60 additional EVSE-ready spaces or EVSE-installed spaces

 

* An accessible parking space is not required by this section if no accessible parking spaces are required by Section 17-10-0902.

For the first required accessible EVSE-ready space or EVSE-installed space, the electric vehicle supply equipment infrastructure may be located so that the electric vehicle supply equipment will be located on an accessible route and may be shared by an accessible parking space and a parking space not required to be accessible. Otherwise, both an accessible parking space and a parking space not required to be accessible must be EVSE-ready spaces or EVSE-installed spaces.

      17-10-1011-D Use of EVSE Energy Management System. The required electrical capacity to serve either EVSE-installed spaces or EVSE-ready spaces in a parking area with EVSE-installed spaces connected to an EVSE energy management system may be determined based on the use of an EVSE energy management system that is designed by an Illinois-licensed professional engineer and is capable of providing at least 12 kWh to each space over an 8-hour period when all spaces are occupied by charging electric vehicles (at least 1.5 kW average power delivered).
