Guidelines for Accessibility and ADA Compliance EV Charging Stations must comply with provisions of the Americans with Disabilities Act (ADA). In 2013, the Governor s Office of Planning and Research, in cooperation with the Division of the State Architect, issued draft guidelines entitled, Plug- in Electric Vehicles: Universal Charging Access Guidelines and Best Practices The Guidelines begin with a clear advisory regarding the positive mandate to provide ADA accessibility. ADVISORY: EVG- 250 Electric Vehicle Charging Stations. A reasonable portion of Electric Vehicle Charging Stations are required to be accessible. If provided by a state or local government on public property or on- street within the public right of way, vehicle charging is considered a program or service that must be accessible to and useable by individuals with disabilities. Accessibility covers not just the physical dimensions of the charging station, and operable parts of the device, but also the functionality of the self- contained, closed product charging system. If provided at privately owned or operated public accommodations they must also be accessible as a service provided to the general public. Accessibility standards can now be found in the 2016 California Building Code Section 11B-812 Electric Vehicle Charging Stations. Introduction to the ADA: The Americans with Disabilities Act (ADA) became federal law in 1990 with the intent to prohibit discrimination of individuals on the basis of disabilities. Title I of the ADA prohibits private employers, state and local governments, employment agencies and labor unions from discriminating against qualified individuals with disabilities in job application procedures, hiring, firing, advancement, compensation, job training, and other terms, conditions, and privileges of employment. The ADA covers employers with 15 or more employees, including state and local governments. An employer is required to make a reasonable accommodation to the known disability of a qualified applicant or employee if it would not impose an undue hardship on the operation of the employer s business. Reasonable accommodations are adjustments or modifications provided by an employer to enable people with disabilities to enjoy equal employment opportunities. The Equal Employment Opportunity Commission (EEOC) is the enforcing agency for Title I. Title II of the ADA addresses State and local government services, and Title III addresses places of public accommodation and commercial facilities. Under titles II and III of the ADA, the Access Board develops and maintains accessibility guidelines for buildings, facilities, and transit vehicles and provides technical assistance and training on these guidelines. The Department of Justice (DOJ) is 20

21 the enforcing agency for Title II, and the Department of Transportation, along with the DOJ are the enforcing agencies for Title III. Accessible Electric Vehicle Charging Stations Since public charging stations offer a service to the general public, the ADA prohibits discrimination of individuals on the basis of disabilities. Accessibility standards specific to public electric vehicle charging stations are in the California Building Code Part 2 Vol. 1 Chapter 11B Section 812. New Construction or Alterations Electric Vehicle Charging Station (EVCS): The number of charging ports that can simultaneously charge vehicles are considered the number of EVCS at a facility for regulatory purposes When EVCSs are installed, accessible EVCSs complying with Table 11B shall be provided. Exception: EVCSs not available to general public or for the owner of a residence in public housing need not comply. However, there may be future obligation for reasonable accommodation request based on ADA Title I Employment provisions. When new EVCSs are added to a site with existing EVCSs, total of new + existing EVCSs used for scoping. Technical provisions apply only to new EVCSs; no requirement to retrofit existing EVCSs unless they are altered or upgraded. Operable parts on ALL new EVCSs must comply with Operable Parts requirements in 11B EVCS Installation Example #1 21

22 No ISA (International Symbol of Accessibility blue placard) required for installations of 1 to 4 EVCS, accessible EVCS available to all. EVCS Installation Example #2 Scoping Provisions EVCS Types Van Accessible 12 feet (144 inches) minimum width 18 feet (216 inches) minimum length Access aisle 5 foot (60 inches) minimum width located on passenger side with head-in parking, may be shared with another EVCS vehicle space Accessible route requirements to EVSE and areas served by EVCS Standard Accessible 9 feet (108 inches) minimum width 18 feet (216 inches) minimum length 22

23 Access aisle 5 foot (60 inches) minimum width either side of space, can be shared with another EVCS space Accessible route requirements to EVSE and areas served by EVCS Ambulatory No comparable requirement in accessible parking. 10 feet (120 inches) minimum width 18 feet (216 inches) minimum length No access aisle required; additional width of space provides increased access for individuals with limited or temporary mobility challenges Accessible route requirements to EVSE, facility entrance or site arrival point Drive-Up No comparable requirement in accessible parking, analogous to motor fuel pump island at filling stations. 17 feet wide (204 inches) 18 feet long (216 inches) No access aisle required Accessible route requirements to EVSE, facility entrance or site arrival point 23

24 EVCS Designated for the Disabled EVCS for the exclusive use of the disabled shall be identified by a sign mounted International Symbol of Accessibility (ISA). 11B Identification provides for EVCS reserved for use by the disabled. Table 11B indicates type and number of EVCS that must be identified with an ISA. No ISA required for small scale installations with 1 to 4 EVCS, accessible EVCS available to all. If properly signed per local ordinance, EVCS charging time limits apply to all users: Vehicle Code Section Vehicles with disabled placards or license plates may park for unlimited periods of time in zones where the length of time is restricted or metered. EVCSs are zones reserved for special types of vehicles, per DMV, in which right to park for unlimited periods of time does not apply. Path of Travel A Path of Travel (POT) needs to be present from an Accessible EVCS to the nearest Accessible Path of Travel. Exceptions o EVCS installations at facilities where vehicle fueling, recharging, parking or storage is NOT a primary function: Compliance with 11B for POT upgrades not required. o EVCS installations at facilities where vehicle fueling, recharging, parking or storage is a primary function: Cost of compliance for required POT elements is limited to 20% of the adjusted construction cost. Upgrade of Existing EVCSs EVCSs not considered site arrival points per US Access Board. Upgrade of existing EVCSs as POT elements is not triggered by alteration projects under 11B Upgrades may be required when existing EVCSs are updated or altered. 24

25 EV Related Signage Local and State agencies posting guidance or regulatory signs on public roadways, must do so in conformance with the current edition of the California Manual on Uniform Traffic Control Devices (CA MUTCD). Sign sizes, shapes and colors vary based upon the type of message, whether an international symbol exists, and the type of roadway where the sign is to be used. General Service Sign approved in the California MUTCD Regulatory Signs G66-21B (CA) Regulatory signs are required for enforcing the time duration and days that electric vehicles are permitted to park and/or charge at public charging stations. Qualifying electric vehicles should be defined in local codes, and their charging status addressed (plugged in and charging, not charging, disconnected, etc.) References R-112 (CA) R-113 (CA) R-114 (CA) Governor s Office of Planning and Research 25
