Summary Title: AB 1236 - Electric Vehicle Supply Equipment
Title: Adoption of an Ordinance Requiring Expedited Permitting Procedures
for Electric Vehicle Charging Stations (AB 1236)
From: City Manager
Lead Department: Development Services Department
Recommendation
Staff recommends that City Council adopt the proposed ordinance (Attachment A), which
outlines an expedited and streamlined permitting process for electric vehicle charging stations
in compliance with Assembly Bill 1236, and find the ordinance exempt from review under the
California Environmental Quality Act (CEQA).
Background
Assembly Bill 1236, adopted in October 2015, added Government Code Section 65850.7 to
require jurisdictions with a population of less than 200,000 to establish procedures for
expedited, streamlined processes for permitting of electric vehicle charging stations. Under
Section 65850.7, a jurisdiction must adopt an ordinance for the expedited, streamlined process
on or before September 30, 2017. The ordinance must include the requirement that a
jurisdiction adopt a checklist of requirements with which a permit application for an electric
vehicle charging station will be eligible for expedited review. Essentially the Assembly Bill is
attempting to remove unreasonable barriers to the installation of electric vehicle charging
stations and not unreasonably restrict the ability of homeowners and business concerns to
install electric vehicle charging stations. The purpose of this Assembly Bill is to promote and
encourage the use of electric vehicle charging stations and to limit obstacles to their use.
An electric vehicle charging station is any level of Electric Vehicle Supply Equipment (EVSE)
station which delivers electricity from a source outside an electric vehicle into a plug-in electric
vehicle. Assembly Bill 1236 suggests that the City’s checklist may be based on the “Plug-In
Electric Vehicle Infrastructure Permitting Checklist” of the “Zero-Emission Vehicles in California:
City of Palo Alto Page 2
Community Readiness Guidebook” published by the Governor’s Office of Planning and
Research.
Discussion
In advance of AB 1236, the Development Services Department had already taken deliberate and
purposeful steps well in advance of the Assembly Bill to streamline and simplify the EVSE
Permitting Process. The Building Official had already created Submittal Guidelines (Attachment
B) for Residential Electric Vehicle Charging Station – Expedited Review, which can be used by an
applicant or contractor by filling in the blanks with the required information and attaching the
manufacturer’s installation instructions, technical specifications, and a simple plan. If all the
information is provided and the proposal complies with the applicable building codes, then the
review and approval process can usually be performed over-the-counter or within a day or two
depending upon workloads and staff levels at the time of submission.
The City currently expedites the review of residential electric vehicle charging stations by
conducting over-the-counter reviews utilizing the current Building Division plan review staff.
Large commercial projects with multiple charging stations that may require the electrical
service upgrades are more complex and require additional coordination with the fire and
utilities divisions. As a result, these large projects are mostly reviewed on a submittal basis
which requires they be distributed to the various departments for a standard 30-day review
process. These larger projects take longer to review and approve because they are more
complex and involve multi-departmental review and approval. The goal is to ensure health and
safety while ensuring a streamlined and predictable review process, which again complies with
the state statute.

Table 1: EVCS Activity for Commercial and Residential Permits
Table 1 represents the total number of EVSE permits issued over the last five quarters. The
height of the bar represents the total number of EVSE permits submitted for review. The blue
portion of each bar represents that total number of EVSE permits that were reviewed Over the
Counter (OTC) while the red represent those that required a standard 30-day review period
prior to issuing the permit. As one can observe the majority of EVSE permits are issued over
the counter (i.e. blue) and those reviewed for 30-days (i.e. red) are typically more complex
commercial projects. The second graph (Table 2) is a break-out of the Residential EVCS permit
activity for the past five (5) quarters. Almost all of the residential EVCS permits have been
reviewed OTC with an average 89% for the past 5 quarters and in some quarters 100% of the
time. In the few cases, where additional review time was required, these EVCS projects
included an electrical service panel upgrade to support the additional electrical loads, thus
more complicated and requiring lengthier review.
City of Palo Alto Page 4
Table 2: EVCS Activity for Residential Permits
To further simplify the permitting process staff is now in the process of developing an online
application process for all residential photovoltaic, solar hot water, and electric vehicle charging
stations by December 31, 2018. The ultimate goal is to be in a position to perform electronic
plan review on these types of applications by January 1, 2019 thereby expediting the review
process.
Resource Impact
Adoption of this ordinance will potentially result in the need for additional staffing resources
during peak periods to accommodate workloads and to update the City website and
guidebooks. As the city pursues its electronic plan check process additional hardware and
software will be necessary to support the review process, where a contracted technologist will
be required to assist with development and implementation of electronic plan reviews and
online applications submittals. Any funding request for additional resources will be contingent
upon approval by the City Council and evaluated as part of subsequent budget cycle.
Environmental Review
Adoption of this ordinance is exempt from environmental review under the California
Environmental Quality Act (CEQA) per CEQA Guidelines sections 15061(b)(3), because it can be
seen with certainty that the proposed ordinance will have no significant negative impact on the
environment.

The information provided in this document is general and intended as a guide only. Each project is unique and
additional requirements may be enforced as deemed appropriate.
PURPOSE
The purpose of this guideline is to assist permit applicants in streamlining the permitting, installation and
inspection process for Residential EV Chargers.
TYPES OF ELECTRIC VEHICLE (EV) CHARGERS
Be aware that there are different types of Electric Vehicle (EV) Chargers. There are 2 basic types of EV
chargers for home use (Level 1 and Level 2).
LEVEL 1
Level 1 Chargers are smaller units that plug directly into a standard 120 volt receptacle outlet. These types
of chargers typically require a longer period of time to recharge the vehicle. As long as the receptacle
outlet being used to plug-in the Level 1 Charger exists, there is no requirement to secure a permit from the
Building and Safety Division. On the other hand, if you will be installing a new 120 volt receptacle outlet
for the charger, you will need to obtain a permit—but you will not need to provide any plans or electrical
load calculations as would be required for the more powerful Level 2 type charging systems.
LEVEL 2
A Level 2 EV charging system requires a 240 volt electrical circuit and charges the vehicle battery much
faster than a Level 1 charger. Level 2 charger installations typically require an electrical permit and
inspections of the installation. In order to obtain the permit you will need to provide some basic
information to show that your existing electrical service can handle the added load.
Installing a Level 2 EV charging system requires changes to building’s electrical wiring. Before installing the EV
charging equipment and the associated wiring, talk to your EV manufacturer about the electrical
requirements for the charger unit to be installed at your home.
Be sure to use a licensed Electrical contractor whose state contractor’s license and insurance are current. The

contractor should follow the installation instructions of the EV charger manufacturer and the requirements of
California Electrical Code.
SUBMITTAL REQUIREMENTS
This Residential EV Charger Permit Guideline has been developed to streamline the permit, installation and
inspection process. In most cases, you or your contractor merely need to fill-in the blanks on this document,
attach the manufacturer’s installation instructions and charger specifications and submit it to the Building
Department at the Development Center for an over-the-counter review and permit issuance.
If all of the information is provided and the proposal complies with the applicable codes, the review and
approval process can usually be performed over-the-counter or within a day or two depending upon
workloads and staffing levels at the time of submittal. Once the permit is issued, the installation may begin.
When the installation is complete, an inspection of the work must be scheduled with the Building Inspector.
Inspections are typically performed on the work day following your request for inspection. Keep in mind that
someone will need to be present during the inspection so that the Building Inspector can access the location
of the electrical meter and EV charger (typically in the garage) and perform torque requirements.
CALIFORNIA ELECTRICAL CODE GENERAL REQUIREMENTS
All Electrical Vehicle Charging Systems shall comply with the applicable sections of the California Electrical
Code, including Article 625.
EQUIPMENT HEIGHT
The coupling means of the Electric Vehicle Supply Equipment shall be stored at a height of not less than 18
inches above the floor level for indoor locations and not less than 24 inches above the grade level for
outdoor locations. (CEC 625.50)
LISTED EQUIPMENT
All Electric Vehicle Supply Equipment shall be listed by a nationally recognized testing laboratory. You can
find a list in the US Department of Labor’s website. (CEC 110.3(B))
FASTENED IN PLACE
Specify if the Level 2 Electric Vehicle Supply Equipment will be permanently connected and fastened in
place in accordance with the manufacturer’s installation instructions.
PROTECTION FROM PHYSICAL DAMAGE
Electrical Vehicle Supply Equipment shall be protected against vehicle impact damage when located in the
path of a vehicle. In order to avoid the installation of a substantial pipe bollard as an equipment guard,
locate the Electrical Vehicle Supply Equipment on a garage side wall, out of vehicular path (see sample
drawing below). (CEC 110.27(B))
IF MORE THAN 60 AMPS
When EV charging equipment is rated at more than 60 amps, the disconnect means shall be provided and
installed in a readily accessible location and shall be capable of being locked on the open position. (CEC
625.42)

Sample Electrical Plan for Level 2 Electric Vehicle Charger Circuit Installation (Source: City of Riverside)
CITY OF PALO ALTO UTILITY REQUIREMENTS
Though an individual Level 2 EV charger may have a negligible impact on the utility electric system, the
combined effect of several chargers in the same neighborhood could result in overloads on utility secondary
wires and transformers. It is important that the City of Palo Alto Utilities be notified of any Level 2 charger
installations to ensure that utility electrical system components are adequately sized to maintain high levels
of service reliability.
For EVSEs greater than 40 amps, or that require an overcurrent protection device (e.g., circuit breaker)
greater than 50 amps, complete the City of Palo Alto Utilities Department EVSE Information form.
