Title 24 · California Energy Code
What are the EV charging readiness requirements for warehouses, grocery/retail, office and manufacturing loading spaces?
For building owners: when you build warehouses, grocery/retail, office or manufacturing buildings with off‑street loading spaces you must, at construction, install spare raceways/busways, reserve transformer and panel capacity per Table 5.106.5.5.1 (200 or 400 kVA depending on size and number of loading spaces), and show charger locations and conduit pathways on the plans so medium‑ and heavy‑duty chargers can be added later without demolition.

What the code requires — 2–4 sentences
Construction for warehouses, grocery/retail, office and manufacturing buildings with planned off‑street loading spaces must provide infrastructure to facilitate future medium‑ and heavy‑duty EV charging: install spare raceway(s) or busway(s) and reserve transformer, service panel or subpanel capacity at construction time, and show locations/pathways in the construction documents. This requirement is the nonresidential EV charging readiness rule in § 5.106.5.5 and specifically § 5.106.5.5.1 (see Table 5.106.5.5.1 for the kVA sizing).
The single most important rule: reserve raceways/busways and the additional transformer/panel capacity called out in Table 5.106.5.5.1 at time of construction so medium‑/heavy‑duty EVSE can be installed later without demolition.
Requirements in detail
High‑level elements required by § 5.106.5.5.1:
- Install spare raceway(s) or busway(s) that originate at the main service panel or a subpanel serving the area and terminate near the planned loading‑space charging locations.
- Provide adequate additional capacity at the transformer, main service equipment and subpanels per the kVA amounts in Table 5.106.5.5.1.
- Show on construction plans: one or more convenient reserved location(s) for medium‑ and heavy‑duty charging cabinets/dispensers and a reserved pathway for conduit routing from the raceway/busway termination to those locations.

(Values and thresholds above are taken directly from Table 5.106.5.5.1 and the text requirements of § 5.106.5.5.1.)
What the raceway/busway must do
- Originate at the main service panel or subpanel serving the loading area and terminate close to the future charger locations.
- Be sized to carry the minimum additional system load (the kVA shown in Table 5.106.5.5.1) to the future charging location.
Exceptions & special cases
- Local enforcing agencies may allow exceptions where compliance is infeasible because: no local utility power supply, the utility cannot supply adequate power, or where required utility infrastructure upgrades would unreasonably impact construction cost. These are the exceptions listed under § 5.106.5.5.
- Remote parking facilities without access to the building service panel or other impracticable conditions may also be excluded under the broader EV requirements/exception language in Chapter 5 (see § 5.106.5.4 for related exceptions).
Common mistakes
- Installing raceways that are too small or not sized to carry the kVA listed in Table 5.106.5.5.1 — raceway size must match the additional capacity requirement.
- Failing to show the reserved location(s) and conduit pathway on construction drawings — the rule requires these be indicated in construction documents.
- Not reserving panel space or failing to increase transformer capacity per the table — the transformer and main service equipment must meet the minimum kVA requirement.
- Overlooking coordination with the utility early: some projects will require utility service upgrades to realize the reserved capacity (or qualify for an exception). Document and confirm utility capability during design.
- Confusing these medium/heavy‑duty readiness rules with the passenger‑vehicle EV‑capable parking requirements in § 5.106.5.3.1 (that section adds raceway termination marking and “EV CAPABLE” identification for passenger vehicle parking). If you are doing both, meet both sections’ marking/labeling and sizing rules.
Worked example — concrete scenario
Scenario: New warehouse building, 300,000 sq. ft., with 2 planned off‑street loading spaces.
Step 1 — find the right table row: the warehouse is Greater than 256,000 sq. ft.; for 1 or Greater loading spaces Table 5.106.5.5.1 requires 400 kVA additional capacity. So the project must reserve 400 kVA at the transformer/main service/subpanels and provide raceway/busway sized to carry that additional system load to the loading area.
Step 2 — drawing and raceway work: show on construction documents one or more convenient reserved locations for medium/heavy‑duty charging cabinets/dispensers at the loading spaces and a conduit pathway from the raceway termination to those locations. Ensure raceway sizing calculations reflect the 400 kVA future load.
Step 3 — coordination: verify local utility can supply the extra service capacity or plan utility upgrade actions early (or document why an exception applies under § 5.106.5.5).

Frequently asked questions
Do I need to install chargers now or only the raceway/panel capacity?
You are required to install raceway(s)/busway(s) and reserve transformer/panel capacity per § 5.106.5.5.1; actual medium/heavy‑duty EVSE installation can occur later. Show reserved locations/pathways on the construction documents.
How do I know whether to use **200 kVA** or **400 kVA**?
Use Table 5.106.5.5.1: the kVA depends on building type, building size thresholds, and the number of off‑street loading spaces (the table rows show 200 or 400 kVA by those criteria).
What if the local utility can’t supply the extra capacity?
The local enforcing agency may grant an exception where the utility cannot provide adequate power or no local supply exists — document the utility limitation as part of the permit/approval process under § 5.106.5.5.
Must the raceway terminate inside a cabinet or box?
Yes — raceway(s) should terminate in close proximity to the potential future location of the charging equipment and into a suitable listed cabinet, box or enclosure consistent with electrical code practice, as required by § 5.106.5.5.1.
Does this rule apply to passenger car parking too?
No — these readiness rules specifically address medium‑ and heavy‑duty charging at off‑street loading spaces. Passenger‑vehicle EV requirements are in § 5.106.5.3 and associated tables; if both apply, comply with both sections.
