A. 
Purpose. The purpose of this Section is to promote and encourage the use of electric vehicles, in accordance with California Government Code Section 65850.7, by creating an expedited, streamlined permitting process for electric vehicle charging stations, while promoting public health and safety and preventing specific adverse impacts on the installation and use of such charging stations.
B. 
Definitions.
"Electric vehicle charging station" or "charging station"
means any level of electric vehicle supply equipment station that is designed and built-in compliance with Article 625 of the California Electrical Code, as it reads on the effective date of this Section, and delivers electricity from a source outside an electric vehicle into a plug-in electric vehicle.
"Specific, adverse impact"
means a significant, quantifiable, direct, and unavoidable impact, based on objective, identified, and written public health or safety standards, policies, or conditions as they existed on the date the application was deemed complete.
"Electronic submittal"
means the utilization of one or more of the following: email, the Internet or facsimile.
C. 
Expedited Review Process. Consistent with Government Code Section 65850.7, the Building Official shall implement an expedited administrative permit review process for electric vehicle charging stations and adopt a checklist of all requirements with which electric vehicle charging stations shall comply to be eligible for expedited review. The expedited administrative permit review process and checklist may refer to the recommendations in the checklist prescribed by the most current version of the "Plug-In Electric Vehicle Infrastructure Permitting Checklist" of the "Zero- Emission Vehicles in California:
Community Readiness Guidebook" published by the Governor's Office of Planning and Research. The checklist shall be published on the City's website.
D. 
Permit Application Processing.
1. 
Prior to submitting an application for processing, the applicant shall verify that the installation of an electric vehicle charging station will not have a specific, adverse impact to public health and safety and building occupants. Verification by the applicant includes but is not limited to: electrical system capacity and loads; electrical system wiring, bonding and overcurrent protection; building infrastructure affected by charging station equipment and associated conduits; areas of charging station equipment and vehicle parking.
2. 
A permit application that satisfies the information requirements in the City's adopted checklist shall be deemed complete and be promptly processed. Upon confirmation by the Building Official that the permit application and supporting documents meet the requirements of the City, and is consistent with all applicable laws, the Building Official shall, consistent with Government Code Section 65850.7, approve the application and issue all necessary permits. Such approval does not authorize an applicant to energize or utilize the electric vehicle charging station until final inspection and approval of the installation of the station have been granted by the Building Official. If the Building Official determines that the permit application is incomplete, he or she shall issue a written correction notice to the applicant, detailing all deficiencies in the application and any additional information required to be eligible for expedited permit issuance.
3. 
Consistent with Government Code Section 65850.7, the Building Official shall allow for electronic submittal of permit applications covered by this Section and associated supporting documentations. In accepting such permit applications, the Building Official shall also accept electronic signatures on all forms, applications, and other documentation in lieu of a wet signature by any applicant.
E. 
Technical Review.
1. 
If the Building Official makes a finding based on substantial evidence that the electric vehicle charging station could have a specific adverse impact upon the public health or safety, the Building Official may require the applicant to apply for a use permit in accordance with Chapter 17.60 of this code.
2. 
The Building Official may impose conditions on an electric vehicle charging station permit that are designed to mitigate specific, adverse impacts upon the public health or safety at the lowest cost possible.
3. 
Consistent with Government Code Section 65850.7, the Building Official shall not condition the approval for any electric vehicle charging station permit on the approval of such system by an association, as that term is defined by Civil Code Section 4080.
F. 
Electric Vehicle Charging Station Installation Requirements.
1. 
Electric vehicle charging station equipment shall meet the requirements of Chapter 15.04 of this code, the Society of Automotive Engineers, the National Electrical Manufacturers Association, and accredited testing laboratories such as Underwriters Laboratories, and rules of the Public Utilities Commission regarding safety and reliability.
2. 
Installation of electric vehicle charging stations and associated wiring, bonding, disconnecting means and overcurrent protective devices shall meet the requirements of Chapter 15.04 of this code.
3. 
Installation of electric vehicle charging stations shall be incorporated into the load calculations of all new or existing electrical services and shall meet the requirements of Chapter 15.04 of this code. Electric vehicle charging equipment shall be considered a continuous load.
4. 
Anchorage of either floor-mounted or wall-mounted electric vehicle charging stations shall meet the requirements of Chapter 15.04 of this code, and the provisions of the manufacturer's installation instructions. Mounting of charging stations shall not adversely affect building elements.
G.
