Are you allowed a parking "credit" for adding an EVC station? - California

For example, if I am required to have 100 spaces on my site and install 4 EVCS spaces, I would be allowed to have only 96 spaces on my site. I seem to remember seeing that on the CBC but I can't find it.
 
Typically, parking requirements are a municipal requirement, not a building code item. Therefore, it will vary city to city.
 
First review the definitions in CBC 202, and note how the word "parking" does not occur in any of them:

ELECTRIC VEHICLE (EV) CHARGER. Off-board charging equipment used to charge an electric vehicle.

ELECTRIC VEHICLE CHARGING SPACE (EV Space). A space intended for charging electric vehicles.

ELECTRIC VEHICLE CHARGING STATION (EVCS). One or more electric vehicle charging spaces served by an electric vehicle charger or other charging equipment. Where a multiport electric vehicle charger can simultaneously charge more than one vehicle, the number of electric vehicle charging stations shall be considered equivalent to the number of electric vehicles that can be simultaneously charged.

ELECTRIC VEHICLE (EV) CONNECTOR. A device that, when electrically coupled (conductive or inductive) to an electric vehicle inlet, establishes an electrical connection to the electric vehicle for the purpose of power transfer and information exchange. This device is part of the electric vehicle coupler.

Think of it this way: the EV Space is the ground surface "reserved" for electric vehicles. An EVCS is the ground space plus the charging equipment. It's important to make the distinction between "space" and "station". For example, some jurisdictions may incentivize EV use by prioritizing their location close to the main building entrance, even though there's no charging device.

Seriously though, per the CBC definitions, a particular space might be:
  • An EVCS but not a parking space (like how at a conventional gas station, the space next to the gas pump is not intended for parking, just for filling up).
  • A parking space but not a EV space (a conventional parking stall for any kind of vehicle, gas or electric)
  • Both a parking space and an EV space
The key is whether you or your zoning code considers an EVCS to also be a parking space. Again, this is akin to asking whether the area next to a gas pump is a parking space.
  • If the intent of an EVCS is to have the electric vehicle move to another parking space once the vehicle has been fully charged, then it is not a parking space.
  • If you zoning code allows an electric vehicle to park at an EVCS if they won't be charging the vehicle at all, then it may be considered a parking space.
Once you've made that determination, then you can apply Cal Green:

California. Does anyone have any idea on how to determine the quantity of EVCS for an existing facility?

When I look at Cal Green there are Mandatory measures and Voluntary measures. I assume mandatory is for new construction, and that voluntary would most likely be used for existing buildings as there were no requirements when the building was constructed and the owner would just like to add some EVCS. per A5.106.5.3 and with a parking count of 755 spaces they are looking for 15% or 20% of the total depending upon tier 1 or tier 2....which by the way is the most complicated bunch of crap I cannot even decifer. Mandatory measures per 5.106.5.3.3 require 10% of the total spaces. So voluntary requires possibly double the spaces? How is this the most ridiculously complicated code language ever?
 
Check out Assembly bills 1236 and 970 which requires local jurisdictions to adopt an ordinance by Jan 1 2023, the specifics of the ordinance are available in some pdf's I have but I'm not able to post here. If you want to send me your email in a private message I can send them to you. I'm sure you could find them in a google search too.

The text of the email that was sent to me I can post:

Hello Joe,

My name is Benjamin Tuggy and I’m reaching out from the California Energy Commission. My office is working with The Governor’s Office of Business and Economic Development (GO-Biz) to provide jurisdictions with resources regarding AB 1236 (2015) and AB 970 (2021).

AB 1236 requires all cities and counties to streamline Electric Vehicle Charging Station (EVCS) permitting by:
1. Adopting an EVCS permit streamlining ordinance with 7 key components (see Scorecard)
2. Posting EVCS permit checklists for both residential and non-residential applicants online (if a jurisdiction operates a website). It’s possible to combine into one form (Example: Sonoma County Checklist)

GO-Biz has been tracking the adoption status of every city and county in California laid out in AB 1236 (2015). Per those records, the XXXXXXXXXX has not implemented AB 1236. Also, AB 970 (2021) will codify permitting timelines and parking considerations. AB 970 will be effective for small jurisdictions (population of 200K and less) starting January 1st, 2023. I’ve attached an AB 1236 + 970 Fact Sheet and a step-by-step Adoption Guide, and here is a link to FAQ’s.

Once your jurisdiction begins implementation, please email Aram Shamsian (CC’d) at GO-Biz to update the state permitting map records. Aram can also answer any questions.

Thank you!
