There is a widespread belief among New York building owners that a law now makes them responsible for the lithium-ion batteries their tenants bring home. Owners ask us how to enforce it.

No such law exists, and the belief is doing real harm — because owners looking for a rule that is not there miss the obligations that genuinely are.

What Local Law 39 actually does

Local Law 39 of 2023 bans the sale, lease, rental or distribution in New York City of e-bikes, powered mobility devices and batteries that do not meet recognized safety standards, certified by accredited testing labs. The two standards named are UL 2849, covering the e-bike's electrical system as a whole, and UL 2271, covering the battery.

Between them they test what actually kills people: shock risk while charging, the safety of storing the battery, and the integrity of the whole electrical system.

It is enforced against sellers. A first offense draws a warning; a second has been reported at up to $1,000, with maximum penalties raised to as much as $2,000 per device type, and the city gained power to force the closure of shops that repeatedly sell uncertified batteries.

A landlord does not get fined under Local Law 39 because a resident owns an uncertified battery. That is worth stating plainly, because owners who believe otherwise tend to respond with a blanket prohibition they think the city requires — and then stop thinking about the problem.

The obligations that are real

A shared charging or storage room crosses a threshold at six devices. Where a building provides shared space in which six or more e-bikes or similar micromobility devices are stored or charged, that room must meet fire safety standards — reported to include sprinkler protection, smoke detection, signage, and at least one-hour fire-rated separation from the rest of the building.

That is a construction project. It is not a corner of the basement with a power strip and a sign, and a building that has informally accumulated seven or eight bikes in a storage room has very likely crossed into a requirement it has never assessed.

The FDNY requires a posted bulletin. Residential buildings must display a Fire and Emergency Preparedness Bulletin covering e-bike storage and charging safety, alongside the other fire safety notices and preparedness materials a multiple dwelling has to post and distribute. It costs nothing and it is the single easiest item here to be non-compliant on, because nobody sends a reminder.

And there is ordinary liability. An owner who knows about an unsafe charging arrangement — a bike charging in a stairwell, an extension cord run under a fire door, a visibly damaged battery in a common area — and permits it to continue is exposed if a fire follows. That exposure does not require a specific local law to attach.

Confirm current requirements with the FDNY before designing a charging room or relying on any threshold here. This part of the code has moved quickly and continues to.

Charging cabinets, and a date that is not your date

If you are considering an actual battery charging cabinet, those go through FDNY approval, with UL 1487 as the governing certification for the products themselves.

You may encounter a September 2026 date attached to this. Be careful with it: it refers to an extended filing window under FDNY's Letters of No Objection process for outdoor grandfathered cabinets, which is a narrow program. It is not a general deadline requiring residential buildings to do anything by 1 September 2026, and it has been repeated online as though it were.

If a cabinet is on your table, take the approval path to the FDNY for your specific installation.

Why a blanket ban is often the wrong answer

Owners are legally free to decline. The Department of Transportation's bike parking program covers human-powered devices and does not extend to battery-powered ones, so no rule obliges a building to provide storage for e-bikes.

The trouble is what a ban actually achieves.

A delivery worker who depends on an e-bike for income does not stop owning one because the lease prohibits it. The bike comes inside anyway, and the battery gets charged in an apartment, behind a closed door, on a cheap replacement charger, out of sight of anyone who might notice it swelling. A prohibition converts a visible risk into an invisible one, and the fire — when it happens — starts in a unit rather than in a sprinklered room.

This is the genuine judgment call in the topic, and it is building-specific. A walk-up with two residents who own e-bikes has a different problem than a building housing several delivery workers. The realistic options are a supervised, compliant charging space if the building can support the construction; clear rules on where charging may and may not occur if it cannot; or a prohibition that is actually enforced rather than a clause nobody looks at.

What does not work is a lease clause banning e-bikes, no charging provision, and no inspection — which is the arrangement most Brooklyn buildings currently have.

What to do this quarter

  • Count the devices. If a shared space is holding six or more, get the room assessed against the fire safety standards before anything else.
  • Post the FDNY bulletin. Free, required, and commonly missing.
  • Give residents the charging rules in writing: manufacturer's charger only, no extension cords, never near an exit or combustibles, stop using a damaged or swollen battery immediately.
  • Walk the common areas. Stairwells, hallways, boiler and storage rooms. Charging in an egress path is the condition to eliminate first.
  • Ask your insurance broker, in writing, what the policy says about lithium-ion fires and about any charging facility the building provides. Some policies have added exclusions, and you want that answer before you decide what to permit — the same discipline covered in landlord insurance in NYC.
  • Decide deliberately, and write it down. A policy the building actually follows beats a stricter one it does not.

Where this sits in management

This is a fast-moving area where the rules genuinely have changed more than once, the widely repeated version is frequently wrong, and the consequence of getting it wrong is a fire rather than a fine. Tracking it — and separating a real obligation from an internet summary of one — is part of how we run apartment building management alongside the legal and regulatory compliance calendar.

If your building has bikes accumulating in a storage room and no policy, schedule a consultation or call 718-568-9278.
