Installing EV Charging Stations? Here Are 10 New Fire Safety Codes You Should Know

As electric vehicle (EV) adoption accelerates across North America, commercial building owners, facility managers, and general contractors are rapidly integrating charging infrastructure into warehouses, hospitals, and high-rise parking structures. While the benefits of sustainability and tenant satisfaction are clear, the introduction of high-voltage charging systems and large-scale lithium-ion battery storage introduces significant new fire risks, most notably thermal runaway.
Authorities Having Jurisdiction (AHJs) are increasingly implementing rigorous local amendments and adopting new sections of the NFPA (National Fire Protection Association) and International Fire Code (IFC) to address these hazards. At Safeway Fire Protection, we recognize that maintaining fire safety compliance is no longer a matter of basic electrical installation; it is a complex intersection of fire suppression, detection, and structural safety.
Below are 10 critical fire safety codes and standards you must understand before installing EV charging stations in your commercial facility.
1. Mandatory Listing and NFPA 70 Compliance
All electric vehicle supply equipment (EVSE) must be UL-listed and installed in strict accordance with NFPA 70, the National Electrical Code (NEC). Specifically, Article 625 governs the wiring, protection, and ventilation requirements for EV charging systems. Failure to use listed equipment can result in immediate project shutdown by the AHJ and may void insurance coverage in the event of an incident. We emphasize that fire alarm installation and electrical infrastructure must be coordinated to ensure the power supply is integrated into the building’s broader life safety strategy.
2. Reclassification of Sprinkler Hazard Density
Traditional parking garages have historically been classified as "Ordinary Hazard Group 1" or "Group 2" for sprinkler design. However, many jurisdictions: including San Francisco and Boise: have recently moved to reclassify parking areas with EV charging as "Extra Hazard Group II." This requires a significant increase in water density, often upwards of 0.40 gpm/ft² over the design area.
If you are retrofitting an existing garage, your current system may not meet these requirements. Conducting professional fire sprinkler inspections is the first step to determining if your system requires hydraulic modification or pump upgrades to accommodate this increased demand.
3. Thermal Runaway Detection Protocols
Standard smoke detectors are often insufficient for detecting the early stages of a lithium-ion battery fire, which may begin as an internal chemical reaction (thermal runaway) before visible smoke appears. New local codes are increasingly mandating the installation of heat detectors or specialized multi-sensor gas detectors in enclosed or underground parking areas. Proper fire alarm inspections must ensure these sensors are integrated into the main fire alarm control panel (FACP) to provide early warning to both occupants and first responders.
4. Emergency Disconnect (Rapid Shutdown) Requirements
The upcoming 2026 edition of the NEC is expected to formalize requirements for emergency disconnects on EV charging stations. This allows fire departments to quickly de-energize the entire charging bank during an emergency, reducing the risk of electrical shock to firefighters and preventing further thermal escalation. These disconnects must be clearly labeled and positioned in an accessible, non-hazardous location approved by the fire marshal.
5. Location Restrictions and Egress Separation
New amendments to the International Building Code (IBC) and IFC are placing stricter limits on where chargers can be placed. In many regions, Level 3 (DC Fast) chargers are being prohibited in enclosed parking structures or underground basements due to the intensity of potential fires. Furthermore, codes often require a minimum separation of 20 feet from any means of egress. Ensuring that a fire at a charging station does not block emergency exit paths is a vital component of a compliant facility design.
6. Energy Storage Systems (ESS) and NFPA 855
Many commercial sites are pairing EV chargers with on-site battery storage systems to manage peak demand. If your installation includes stationary batteries, you must comply with NFPA 855. This standard dictates:
Fire-resistance ratings for ESS rooms.
Maximum allowable energy capacity per fire area.
Ventilation and explosion-control requirements.
Integration with fire sprinkler maintenance schedules to ensure high-output suppression is always ready.
7. Physical Protection and Vehicle Impact Barriers
The IFC requires that EVSE be protected from physical damage. In a parking environment, this typically means the installation of heavy-duty steel bollards or concrete barriers. A vehicle accidentally striking a charger can cause a catastrophic short circuit or mechanical breach of the charging cable, leading to an electrical fire. These barriers must be designed to withstand a significant impact without compromising the charging unit.
8. Fire Service Access and Clearances
Charging stations cannot obstruct fire department access. Fire lanes must remain clear, and the charging infrastructure (including cables) must not impede the deployment of fire hoses or the positioning of aerial ladders. When we perform site surveys for fire sprinkler maintenance, we evaluate whether new infrastructure has created "blind spots" or obstructions for fire service personnel.
9. Portable Fire Extinguisher Placement
While water is the primary agent for cooling a lithium-ion battery fire, the surrounding electrical infrastructure still requires appropriate portable fire extinguishers. NFPA 10 standards mandate the placement of Class BC or ABC extinguishers within a specific travel distance (usually 75 feet) of charging stations. Building owners must ensure these units are part of a regular monthly and annual inspection program to maintain compliance.
10. Rigorous Inspection and Documentation
Finally, the introduction of EV charging increases the complexity of your building’s risk profile. Standard fire sprinkler inspections and fire alarm inspections must now account for these high-hazard zones. Documentation is critical; insurance providers and AHJs require detailed records showing that suppression systems have been tested against the specific hydraulic demands of the EV charging area.
Conclusion: Mitigating Risk through Professional Partnership
Installing EV charging stations is a forward-thinking investment, but it must be balanced with a disciplined approach to fire safety. The codes are evolving rapidly, and the margin for error is slim when dealing with high-voltage systems and lithium-ion batteries.
