Title 24 · California Energy Code
What does the code require for EV capable spaces, raceways and panel capacity at commercial sites?
In plain terms: the California code (see **§ 5.106.5.3.1**) requires commercial parking to provide a specified number of EV‑capable spaces, each served by a minimum **1‑inch** raceway back to the service panel and reserved panel space + load for a **208/240 V, 40 A** branch circuit (with **30 A** delivery to an EVSE). Mark the reserved breaker space and raceway as **“EV CAPABLE,”** ensure overall service/transformer capacity, and follow Table 5.106.5.3.1 for counts and reductions if EV chargers are already installed.

What the code requires — 2-4 sentences
The California code requires that commercial parking provide a specified number of EV capable spaces (see Table 5.106.5.3.1) and that each EV capable space be served by a reserved raceway and reserved panel space / electrical load capacity sized to allow a future dedicated 208/240‑volt, 40‑ampere branch circuit (delivering 30 amperes minimum to an installed EVSE). The controlling rule is § 5.106.5.3.1 — which mandates the raceway size, branch‑circuit reservation, system capacity, and visible “EV CAPABLE” marking for the panel and raceway termination.
The single most important requirement: provide a listed raceway (minimum 1‑inch) from the service panel/subpanel to each EV capable space and reserve panel space + capacity for a 208/240 V, 40 A branch circuit for every EV capable space. § 5.106.5.3.1
Requirements in detail
Short list (plain)
- Provide the number of EV capable spaces required by Table 5.106.5.3.1 (round up per table note). § 5.106.5.3.1
- Provide one or more listed raceways (minimum 1‑inch / 25 mm) originating at the service panel or subpanel and terminating near each EV capable space. A common raceway may serve multiple spaces. § 5.106.5.3.1
- Reserve panel space and electrical load capacity for a dedicated 208/240‑volt, 40‑ampere minimum branch circuit for each EV capable space, with delivery of 30 amperes minimum to an installed EVSE. § 5.106.5.3.1
- Ensure the electrical system and any on‑site distribution transformers have sufficient capacity to supply full rated amperage at each EV capable space. § 5.106.5.3.1
- Identify reserved breaker space(s) in the panel directory and mark the raceway termination location as “EV CAPABLE.” § 5.106.5.3.1
Decision‑relevant dimensions / values (quick table)
| Requirement | Required value / action | Code reference |
|---|---|---|
| Minimum raceway inside diameter | 1‑inch (25 mm) | § 5.106.5.3.1 |
| Branch circuit reserved per EV capable space | 208/240 V — 40 A minimum (dedicated) | § 5.106.5.3.1 |
| Minimum delivery from installed EVSE | 30 A | § 5.106.5.3.1 |
| Panel directory marking | Reserved overcurrent device space(s) labeled “EV CAPABLE” | § 5.106.5.3.1 |
| Raceway termination marking | Permanently and visibly marked “EV CAPABLE” | § 5.106.5.3.1 |
| Number of required EV capable spaces | See Table 5.106.5.3.1 (examples in table rows) | § 5.106.5.3.1 / Table 5.106.5.3.1 |
| Rounding rule for counts | Round up to nearest whole space | Table note, § 5.106.5.3.1 |
| Reduction when EVCS already installed | Each EVCS reduces the number of required EV capable spaces by the same number (per table note) | Table note, § 5.106.5.3.1 |
| At least one Level 2 EVSE | At least one Level 2 EVSE required where EVCS are provided | Table note, § 5.106.5.3.1 and § 5.106.5.3.2 |
Notes: The table in the code (Table 5.106.5.3.1) lists specific counts for ranges of total parking spaces (e.g., 10–25, 26–50, etc.) — consult Table 5.106.5.3.1 in § 5.106.5.3.1 for the exact required counts.
Additional technical details (related items cited in code)
- A common raceway may serve multiple EV capable spaces (helps reduce trenching/cost). § 5.106.5.3.1
- The requirement is tied to providing capacity for a future EVSE: raceway must terminate into a listed cabinet/box/enclosure in close proximity to the proposed parking location. § 5.106.5.3.1
- Where EVCS are installed, Section 5.106.5.3.2 explains EVSE types, receptacle configurations, and how installation of DCFC or multiple connectors may reduce the number of required EV capable spaces and the required panel load. § 5.106.5.3.2
- Automatic Load Management Systems (ALMS) are permitted and, when used, may reduce required electrical load capacity; ALMS‑controlled EVSE must still deliver 30 A when charging a single vehicle and 3.3 kW minimum while simultaneously charging multiple vehicles. § 5.106.5.3.3
Exceptions & special cases
- The code allows exceptions where compliance is not feasible because: no local utility power supply, the utility cannot supply adequate power, or additional utility infrastructure requirements would unreasonably increase construction cost — these are evaluated case‑by‑case by the enforcing agency. See § 5.106.5.3 (Exceptions).
- Parking served by parking lifts or automated mechanical parking systems may be excluded if the facility is incapable of supporting EV charging. § 5.106.5.3 (Exceptions) and § 5.106.5.3.1 notes.
- Installing a DCFC EVSE or two low‑power Level 2 receptacles can reduce the number of required EV capable spaces per the reductions described in § 5.106.5.3.2 (see the reductions allowed and how they affect electrical load).
Common mistakes
- Installing a raceway smaller than 1‑inch or not routing it from the service panel/subpanel — the minimum size and origin are explicit in § 5.106.5.3.1.
- Failing to reserve panel space or failing to plan the panel directory identification “EV CAPABLE.” Inspectors commonly see missing reserved breaker spaces even when raceway is provided. § 5.106.5.3.1
- Miscounting required spaces or not rounding up per the table note in Table 5.106.5.3.1. Always apply the table and round up. § 5.106.5.3.1 / Table 5.106.5.3.1
- Assuming a smaller conductor or different receptacle standard will be acceptable — the code prescribes a reserved 208/240 V, 40 A circuit (30 A delivery) as the baseline for EV capable space readiness. § 5.106.5.3.1
- Not marking the raceway termination location visibly as “EV CAPABLE.” This is required by the section. § 5.106.5.3.1
Worked example — 120‑space commercial parking (non‑office/retail)
Scenario: A commercial site (not office or retail) provides 120 actual parking spaces.
- Determine number of required EV capable spaces: consult Table 5.106.5.3.1 — the row 101–150 requires 25 EV capable spaces. Round rules already covered; 120 falls in that range so you need 25. § 5.106.5.3.1 / Table 5.106.5.3.1
- Required EVCS (EVSE installed): for “other than office and retail” the same row lists 12 required EVCS. That means if you elect to install EVCS now, you must provide 12 EV charging stations (Level 2 or as allowed by § 5.106.5.3.2). § 5.106.5.3.1 / Table 5.106.5.3.1
- Raceway and panel reservations: For each of the 25 EV capable spaces you must provide:
- a listed raceway (minimum 1‑inch) originating at the service panel/subpanel and terminating near the parking space into a listed box/enclosure (a common raceway may be used where applicable), and
- reserved panel space and electrical load capacity for a dedicated 208/240 V, 40 A branch circuit for each space (deliver 30 A minimum when EVSE is installed). § 5.106.5.3.1
- System capacity check: ensure the service, distribution transformers, and feeders are sized so they can supply the full rated amperage at each EV capable space if all were simultaneously charging; otherwise, discuss ALMS or power allocation alternatives per the code. § 5.106.5.3.1 and § 5.106.5.3.3
Practical notes: you can use a common raceway to reduce trenching; you must mark reserved breaker spaces “EV CAPABLE”; and adding DC fast chargers or other permitted configurations can change the number of required EV capable spaces per § 5.106.5.3.2.

Frequently asked questions
How is an “EV capable space” counted if an EV charger is already installed?
If an EVCS (installed EV charger) is already provided, each installed EVCS reduces the number of required EV capable spaces by the same number, per the table notes in § 5.106.5.3.1.
Do I have to install conduit all the way to each parking stall?
You must provide a listed raceway (minimum 1‑inch) that originates at a service panel or subpanel and terminates in close proximity to the proposed EV capable space into a listed cabinet/box/enclosure. A common raceway may serve multiple spaces. § 5.106.5.3.1
Can I use Automatic Load Management (ALMS) to avoid upsizing the service?
Yes — § 5.106.5.3.3 permits ALMS and allows reduced required electrical load capacity for EVSE under ALMS, subject to the delivery minimums laid out in that section.
What marking is required at the panel and at the raceway termination?
The panel directory must identify reserved overcurrent protective device space(s) as “EV CAPABLE”, and the raceway termination location must be permanently and visibly marked “EV CAPABLE.” § 5.106.5.3.1
Are there feasibility exceptions?
Yes — the enforcing agency may grant exceptions where local utility power is absent or inadequate or where required utility infrastructure would unreasonably affect construction cost; also parking lifts/automated parking may be excepted. See § 5.106.5.3 exceptions.
