Commercial EV charger installation in California is not a simple equipment purchase. Title 24 compliance, building permits, dedicated circuit work, and utility coordination all come into play before the first vehicle charges. This guide breaks down what the process looks like, what it typically costs, and what your electrical infrastructure needs to handle it.
What Title 24 Requires for Commercial Properties
Title 24 is California’s building standards code. For commercial properties, EV charging requirements fall under CALGreen, which is Part 11 of Title 24. These standards apply to new construction and to projects that add or modify parking spaces under a building permit.
The 2025 California Building Standards Code, effective January 1, 2026, raised the requirements for non-residential properties significantly. New commercial construction must now provide a larger share of parking spaces with Level 2 EVSE fully installed, not just conduit rough-in. Local jurisdictions can also adopt reach codes that exceed state minimums, so requirements in Orange County may differ from those in Los Angeles or Riverside.
There are three levels of EV readiness the code references:
- EV Capable: Conduit is in place with no circuit or charger installed.
- EV Ready: Conduit and a dedicated 40-amp circuit are in place. No charger installed.
- EVSE Installed: A fully operational Level 2 charger is connected and ready to use.
Before any design work begins, confirm the requirements with the Authority Having Jurisdiction (AHJ) for your specific city or county. What applies in one municipality is not guaranteed to apply in the next. California’s Building Energy Efficiency Standards are updated on a triennial cycle, and local amendments add another layer.
Permitting a Commercial EV Charger in Southern California
Every commercial EV charger installation in California requires an EV charger permit. California Assembly Bill 1236 prohibits local agencies from requiring a planning or conditional use permit and mandates approval within 20 business days for projects involving one to 25 chargers. The full list of applicable California EV laws is available through the Alternative Fuels Data Center.
Even with AB 1236 streamlining approval timelines, the EV charger permit application still requires specific documentation:
- Load calculations showing the panel can support the new circuit
- A site plan showing panel location, conduit routing, and charger placement
- Manufacturer specification sheets for the EVSE equipment
- Circuit sizing documentation confirming the dedicated branch circuit is rated at 125 percent of the charger’s continuous current draw per NEC Article 625
After the permit is issued, a licensed electrical contractor completes the installation and an inspection by the local Electrical Division signs off before the circuit is energized. Skipping the EV charger permit is not a shortcut. Unpermitted work creates liability exposure for property owners and may affect utility coverage and insurance claims.
What Drives the Cost of Commercial EV Charger Installation
There is no flat rate for commercial EV charger installation in California. What you pay depends on what your facility already has in place.
Electrical panel upgrade requirements. A Level 2 charger drawing 40 amps of continuous current needs a dedicated circuit rated for at least 50 amps per NEC Article 625.40. If your panel is running near capacity, a panel upgrade is part of the project scope before the charger goes in.
Conduit run distance. The farther your panel sits from the parking area, the more conduit and wire go into the job. Multi-building campuses or facilities with structured parking areas require more planning and more material.
Number of charging stations. One Level 2 station carries a different cost footprint than eight. Automated Load Management Systems (ALMS) can allow more chargers to run on available panel capacity without requiring a full service upgrade, which changes the upfront infrastructure cost significantly.
Utility coordination. Southern California Edison and San Diego Gas and Electric each maintain their own interconnection application processes. For installations that require new or upgraded utility service, plan for a coordination window of 60 to 180 days depending on project scope.
Does Your Panel Have the Capacity?
A load calculation is the required first step before any charger goes in. It tells you whether your existing electrical service can handle the added demand without a panel upgrade.
Many commercial facilities are already running their panels close to capacity. Adding four 50-amp circuits to a panel with limited headroom requires an electrical panel upgrade before any charger installation begins.
Ring and Ping’s commercial electrical services include load calculations, dedicated circuit installation, and panel upgrades as part of the same project scope. You work with one contractor from assessment through installation rather than coordinating separate electricians for the panel work and the charger install. For facilities planning to expand charging capacity over time, our commercial electrical system upgrades are built to support phased rollouts without repeated service interruptions.
Don't Stall Your EV Charging Project on a Permit or a Panel
If your facility needs to meet Title 24 requirements or your fleet is shifting to electric, Ring and Ping handles the load calculation, permitting, panel upgrade, and installation from one point of contact. C-10 licensed, locally based in Santa Ana, and backed by a 90-day labor guarantee on all work. Tell us what your facility needs and we will put together the scope.
How Ring and Ping Handles Commercial EV Charger Projects
Ring and Ping holds a C-10 California Electrical Contractor license, the required credential for commercial EV charger installation in California. We have worked across Orange, Los Angeles, Riverside, and San Diego Counties since 2010.
Our process covers every stage of the project:
- Site assessment and load calculation to confirm available panel capacity
- EVSE selection based on amperage requirements and the number of spaces
- Permit application submitted to the AHJ with all required documentation
- Conduit routing and dedicated circuit installation
- Charger mounting and termination
- Final inspection coordination with the AHJ
Manufacturing and industrial facilities with larger power demands can also work with our manufacturing plant electrical team when EV infrastructure is part of a broader power distribution or panel upgrade project. All work includes a 90-day labor guarantee.
Frequently Asked Questions About Commercial EV Charger Installation in California
Does every commercial EV charger installation in California require a permit?
Yes. A licensed electrical contractor must pull an EV charger permit before any commercial EVSE installation. California AB 1236 limits approval timelines to 20 business days for one to 25 chargers, but the permit itself is required every time.
What does Title 24 actually require for EV charging at a commercial facility?
Title 24, through CALGreen, requires that a percentage of parking spaces in new non-residential construction and qualifying alterations be equipped with EV infrastructure. The 2025 code moves more spaces toward fully installed Level 2 chargers rather than conduit-only rough-in. Requirements vary by parking count and local amendments.
Do I need a panel upgrade before installing commercial EV chargers?
Possibly. A load calculation tells you whether your current panel can support the new circuits. A 40-amp Level 2 charger requires a minimum 50-amp dedicated circuit. If your panel is near capacity, an electrical panel upgrade is required before any charger work starts.
What is the difference between Level 2 and Level 1 EV charging?
Level 1 uses a standard 120-volt outlet and delivers about 1.4 kW, which is not practical for commercial use. Level 2 uses a 208/240-volt dedicated circuit and delivers between 7 and 19 kW depending on the charger’s amperage rating. Nearly all commercial installations use Level 2.
How long does it take to permit and install a commercial EV charger in California?
A single-charger project with adequate panel capacity can typically be installed in one to three days after the permit is issued. Projects requiring panel upgrades or utility service coordination can extend the timeline to several weeks, particularly where investor-owned utility involvement is required.
What license does an EV charger installer need in California?
A C-10 Electrical Contractor license issued by the California Contractors State License Board. Confirm any contractor’s license is active before work begins.
Can I install more chargers without upgrading my electrical service entrance?
Sometimes. If panel capacity is available, additional chargers can be added without a full service upgrade. Automated Load Management Systems can also allow more chargers on existing capacity. A load calculation is the only reliable way to confirm what your facility can support before committing to a scope.
