E-bikes, scooters, and other battery-powered devices are part of everyday life for many tenants. But storing or charging them indoors can lead to serious fire hazards. If a battery fails, the fire can spread quickly, especially in a multifamily building.

That’s why it’s so important for landlords and property managers to understand the risks and how to manage them.

Why Lithium-Ion Batteries Are a Fire Hazard

Lithium-ion batteries power everything from smartphones to power tools to electric bikes. They’re efficient and compact, but when damaged, overcharged, or improperly stored, they can overheat and catch fire. These fires burn hot, spread fast, and are difficult to put out.

In multifamily housing, the danger is even greater. When a fire starts inside an apartment, it can quickly threaten the safety of everyone in the building.

Common Risk Factors

Many battery fires can be traced back to how the device is charged, stored, or maintained. These risks aren’t always obvious, but they’re often preventable.

• Using off-brand or incompatible chargers can lead to overheating and battery failure.
• Leaving devices charging overnight or unattended increases the risk of unnoticed fires.
• Continuing to use damaged or swollen batteries raises the chance of sudden ignition.
• Storing devices near doors or in hallways can block exits and create life safety hazards.
• Relying on outdated or incomplete fire codes means some buildings may not be equipped to manage these risks.

How Landlords Can Reduce Risk

You may not be able to prevent tenants from owning battery-powered devices, but you can take steps to reduce the risk they pose.

• Share battery safety tips from trusted sources like the National Fire Protection Association to help guide tenants to safer charging and storage habits.
• Encourage proper charging practices by recommending certified chargers, unplugging devices once fully charged, and never charging them overnight or while you’re away.
• Post signs in common areas asking tenants not to charge devices in hallways, stairwells, or near exits.
• Create safer charging options like designated outlets or fire-resistant storage containers in garages or basements.
• Inspect common and private areas regularly to spot blocked exits, damaged cords, or signs of unsafe storage.

Education and regular maintenance are your best tools for preventing fire hazards before they start.
