Fire Safety Standards for EV Charging in Parking Garages

Electric vehicles now account for nearly 9 percent of new car sales in the United States, and adoption is climbing fastest in dense suburbs and urban condo markets — exactly the places where parking garages sit underneath people's bedrooms. That stacking has changed how fire marshals, insurers, and HOA boards think about EV charging. A car battery fire in an open lot is a manageable incident. The same fire in an enclosed garage, three stories below occupied units, is a building-evacuation event.

The risk profile is not hypothetical. The 2020 Daejeon garage fire in South Korea and the 2023 Luton Airport garage collapse in the UK — even though Luton's was traced to a diesel vehicle — pushed fire authorities worldwide to revisit garage design, sprinkler coverage, and EV charger placement. In the United States, the National Fire Protection Association (NFPA) and the International Code Council (ICC) have both updated guidance specific to EV charging in parking structures, and your local Authority Having Jurisdiction (AHJ) — usually the fire marshal's office — is the one who will sign off on your project.

For HOA boards and property managers, the practical takeaway is that fire safety is no longer a footnote in an EV charging proposal. It belongs in the project scope from day one, not bolted on after the bids come back.

Multiple overlapping codes govern EV charging installations in parking garages. They are written by different organizations and adopted at different speeds by different cities, which is why two buildings on opposite sides of the same county can face different requirements.

Your installer should reference the specific code edition in force in your jurisdiction. A charger that complies with the 2020 NEC may not comply with the 2023 NEC, and a building permit issued under one cycle does not protect you if the AHJ inspects under a newer cycle. Always ask the installer in writing which code edition the design is built to.

Although requirements vary by jurisdiction, most projects in enclosed or underground garages will need to address the same set of issues. Treat the list below as a starting checklist for your site assessment, not a substitute for a code review.

A good installer will document each of these against the code in force and against the building's existing fire protection system. If a proposal does not mention them, that is a signal the bid is incomplete and probably underpriced.

Code compliance is the floor, not the ceiling. Boards that want to reduce both real-world risk and insurance pressure should consider going further than the minimum. Most of the items below add only a few hundred dollars per stall and pay for themselves the first time they prevent an incident or hold off a premium increase at renewal.

Treat these as a menu rather than a mandate. The right combination depends on the garage layout, the age of the building's electrical system, and how much remote monitoring the management company can realistically support.

Property insurance carriers are paying close attention to EV charging. Several major carriers now ask specific questions about charger type, location, and fire suppression at policy renewal, and a few have raised premiums or excluded coverage for installations that do not meet current code. Before finalizing a charger design, send the plans to your insurance broker. A 30-minute conversation can prevent a coverage gap that would cost the association millions in a worst-case fire.

Resident-facing communication matters too. HOA boards should publish a short policy covering which stalls are for active charging only, what to do if a charger smokes or smells hot, and who to call after hours. Including this in the welcome packet for new owners and posting it at the garage entrance is a low-effort step that materially improves response time when something does go wrong.

Not every electrical contractor has experience with multi-story garages or current fire code. When evaluating installers, push past the equipment list and ask about process. Vendors who lead with these answers, instead of waiting to be asked, are the ones worth shortlisting.

Fire safety in EV charging is straightforward when it is treated as part of the design from the beginning. It is expensive, disruptive, and sometimes impossible to retrofit later. The board's job is to make sure the right questions get asked before the first conduit is run, not after the first inspection failure.
