The sound comes first, a concussion that rattles windows three blocks away. Then glass on the sidewalk, smoke, sirens, and a crowd held back by yellow tape. By evening, there's a news crew, a fire marshal's car and a family standing on the corner in borrowed clothes, wondering where they'll sleep and who, if anyone, is going to answer for what just happened.
New York City has seen this scene before. In March 2014, a gas explosion in East Harlem leveled two buildings and killed eight people. A year later, in March 2015, an explosion in the East Village destroyed several buildings and killed two; an illegal tap into a gas line was found to be the cause, and people involved were later convicted. Each time, the questions afterward were the same. A gas explosion accident lawyer in NYC works through them methodically, because in these cases the answers are rarely simple and the evidence is literally buried in rubble.
Why gas explosions are different from ordinary injury cases
Most injury cases involve one or two parties and a single moment of carelessness. Gas explosions usually involve a chain: a pipe, a fitting, a meter, a work crew, a landlord, a utility, an inspection that happened or didn't. Several parties may share responsibility. Each has insurers and lawyers. And the most important physical evidence is often under the control of investigators, utilities and building owners, not the victims.
That's why these cases depend on getting organized early, with the right experts, the right records and formal requests to preserve evidence before demolition and cleanup erase it.
The usual causes
- Leaking or corroded gas mains and service lines under the street or sidewalk.
- Faulty building gas piping, risers and connections inside the building.
- Illegal or unpermitted work, including unlicensed plumbers tapping into gas lines.
- Construction and excavation damage, when crews strike or weaken a line.
- Defective appliances, valves, connectors or regulators.
- Ignored complaints about the smell of gas.
Who may be responsible
The utility
In New York City, gas is delivered by Con Edison or National Grid, depending on the neighborhood. Utilities are responsible for their mains, service lines and meters, and for responding to leak reports. The New York State Public Service Commission regulates gas safety, and federal pipeline safety rules apply too. After serious incidents, the PSC and sometimes the National Transportation Safety Board investigate. The NTSB's investigation of the 2014 East Harlem explosion, for instance, faulted both a leaking gas main and a city water main problem.
A utility may be liable if it failed to maintain its lines, failed to respond properly to leak reports, or performed work negligently. Utility records, including leak surveys, prior complaints and work orders, are central evidence.
The building owner and landlord
Owners generally control and are responsible for the gas piping inside their buildings, from the meter to the appliances. New York City requires periodic inspections of building gas piping systems in many buildings under Local Law 152 of 2016, and the Department of Buildings maintains related filings. An owner who ignored leak complaints, allowed illegal work or skipped required inspections may be responsible. Our premises liability practice handles claims against owners for unsafe conditions.
Contractors and plumbers
Gas work in New York City generally requires licensed master plumbers and permits. A contractor who performed work improperly, struck a line during excavation, or failed to follow safety rules may be liable. The East Village explosion is a stark reminder of what illegal gas work can cause.
Manufacturers
If a defective appliance, valve, connector or regulator caused the leak, the manufacturer and sellers may be responsible under product liability law. See our product liability guide.
The City
In some cases, a city agency may share responsibility, for example where city infrastructure or city work contributed. Claims against the City generally require a notice of claim within 90 days under General Municipal Law § 50-e. Because it may not be clear early on whether a public entity is involved, it's wise to evaluate this quickly.
The injuries
Explosions cause a distinctive and often devastating range of injuries:
- Burns, including deep burns that require grafting and long-term care.
- Blast injuries, including injuries to the lungs, ears and internal organs from the pressure wave.
- Injuries from flying debris and glass.
- Crush injuries from collapsing structures.
- Smoke inhalation and carbon monoxide exposure.
- Traumatic brain injuries.
- Emotional trauma, including post-traumatic stress, for victims and witnesses.
Our post on burn injuries from fires and explosions covers burn care and damages in more detail, and our guide to brain injury claims explains how TBI cases are proven.
The neighbors, tenants and passersby
Gas explosion claims aren't limited to the people inside the unit where the leak started. Tenants elsewhere in the building, neighbors in adjacent buildings, people walking by, and businesses on the block may all have claims for injuries and losses. Displaced tenants may also have claims for lost belongings and relocation costs. Each person's claim is evaluated on its own facts, but they often share the same core liability evidence.
Evidence: what to do after an explosion
- Get medical care for everyone affected, including for smoke inhalation and hearing problems, which can be overlooked.
- Don't go back into a damaged building until authorities say it's safe.
- Photograph and video whatever you safely can: the building, your unit, your belongings, your injuries.
- Write down every gas smell you or your neighbors noticed before the explosion, and every complaint made to the landlord, the utility or 311, with dates.
- Collect documents: lease, renters' insurance, receipts, and any notices from the landlord about gas work or shutoffs.
- Get names of neighbors and witnesses.
- Request reports: FDNY fire marshal and NYPD reports, and later any utility or regulatory investigation findings.
- Talk to a lawyer quickly about preservation demands to the utility, the owner and contractors, before the site is cleared.
Smell gas? The steps that prevent the next explosion
Not every reader of this page has been in an explosion. If you smell gas, the safety advice from utilities and the City is consistent: leave the area immediately, don't use light switches, phones or anything that might create a spark inside, and once you're outside and away, call 911 and your gas utility. Con Edison and National Grid both publish emergency guidance, and Con Edison's gas safety page explains how to recognize and report a leak.
Reports matter for another reason too. When an explosion happens, prior gas complaints are often among the most important evidence that someone knew of the danger.
Deadlines
| Claim | General deadline |
|---|---|
| Personal injury against a private party (utility, owner, contractor, manufacturer) | 3 years under CPLR 214 |
| Claim against the City or a public entity | Notice of claim generally within 90 days; lawsuit generally within 1 year and 90 days |
| Wrongful death | Generally 2 years from death |
| Property damage | Generally 3 years |
New York's wrongful death law still limits recovery to pecuniary losses; the Grieving Families Act, which would have expanded damages, was vetoed again in December 2025. Our guide to wrongful death claims in Queens explains how those claims work.
Losses beyond the hospital bills
Explosions upend lives in ways that go well beyond medical treatment. When we evaluate a claim, we look at the full picture, which may include:
- Medical expenses, past and future, including burn care, surgeries, grafts, rehabilitation and mental health treatment.
- Lost income and, for serious injuries, lost future earning capacity.
- Pain and suffering, including disfigurement from burns and scarring.
- Property losses: furniture, clothing, electronics, documents, and items that can't be replaced.
- Displacement costs: temporary housing, moving and storage, and the added expense of living elsewhere.
- Business losses for storefronts and offices damaged or closed by the blast.
Renters' and homeowners' insurance may pay some property and displacement costs quickly. Those payments don't replace a claim against the responsible parties, but your insurer may have a right to be reimbursed from any recovery. Keep every receipt, and make a room-by-room list of what was lost while your memory is fresh.
The quieter danger: carbon monoxide
Not every gas-related injury involves a blast. Faulty boilers, water heaters, furnaces and stoves can produce carbon monoxide, an odorless gas that causes headaches, dizziness, nausea and confusion, and at high levels can be fatal. Whole households can be affected at once, and symptoms are often mistaken for the flu.
New York law requires carbon monoxide detectors in most residential buildings, and in New York City owners of multiple dwellings generally must install them in apartments, with tenants responsible for keeping them in working order. When a CO injury happens, the questions resemble those in an explosion case: Was the appliance properly installed and maintained? Did the landlord respond to complaints about the boiler or heat? Were detectors present and working? Who serviced the equipment last? Medical records showing carboxyhemoglobin levels from the emergency room are important evidence, so make sure everyone affected is evaluated.
Tenants: what your landlord still owes you
When a building is damaged or vacated after an explosion, tenants are often unsure of their rights. Depending on the lease and the circumstances, tenants may have rights relating to rent abatement while the apartment is uninhabitable, the return of security deposits, and access to retrieve belongings. Rent-stabilized tenants may have additional rights to return. The City's housing agency and tenant advocacy organizations can help with housing questions, and a lawyer can coordinate those issues with the injury claim so nothing is waived by accident.
Be especially careful with any paperwork a landlord or management company sends after the explosion. Lease surrenders, releases and agreements to accept a payment "in full satisfaction" can affect your rights. Read them, and if you're unsure, ask before signing.
How these cases unfold
Gas explosion cases usually take time. Investigations by fire marshals, regulators and sometimes federal agencies can run for months. Multiple defendants point at each other. Experts in gas systems, fire origin and cause, and engineering are often needed. Cases may be coordinated in court when many victims are involved.
What families can control is the start: getting medical care, documenting losses, and having a lawyer send preservation demands and track every deadline, including any 90-day notice. Everything else builds on that.

Gas explosion FAQ
Who is liable for a gas explosion in New York City?
It depends on the cause. Possible defendants include the gas utility (Con Edison or National Grid), the building owner, contractors or plumbers who worked on the gas system, manufacturers of defective appliances or parts, and in some cases the City. Often more than one party shares responsibility.
Can I sue Con Edison or National Grid for a gas explosion?
Possibly. A utility may be liable if it failed to maintain its gas mains, service lines or meters, failed to respond properly to leak reports, or performed work negligently. Utility records and regulator investigations are often key evidence.
I was a neighbor, not a tenant in the building. Do I have a claim?
You may. Neighbors, passersby and occupants of nearby buildings who were injured, or whose property was damaged, can have claims against the parties responsible for the explosion, just like residents of the building where it started.
How long do I have to file a gas explosion lawsuit in NYC?
Generally three years for personal injury against private parties and two years for wrongful death. If a city agency or public entity may be involved, a notice of claim is generally due within 90 days, so get advice quickly.
What should I do if I smell gas in my apartment?
Leave immediately, don't use light switches, phones or anything that could spark inside, and once you're safely outside, call 911 and your gas utility. Then report it to your landlord in writing. Keep a record of the report.
