Can You File a Lawsuit for Carbon Monoxide Poisoning in an Apartment?

Yes—if carbon monoxide poisoning occurred because a landlord failed to meet their legal responsibilities, you may have a premises liability claim. In New York, landlords are generally required to install and maintain approved carbon monoxide detectors in residential dwellings where required by law. If a landlord fails to comply with those duties or ignores known hazards involving furnaces, boilers, water heaters, chimneys, or ventilation systems, they may be held liable for injuries caused by carbon monoxide exposure.

Carbon monoxide (CO) is an odorless, colorless gas that cannot be detected without a functioning alarm. Because exposure often occurs inside apartments and residential buildings, these cases frequently involve premises liability rather than simply a medical diagnosis. The central legal question is whether the property owner or manager failed to maintain a reasonably safe living environment.

If you or a family member suffered carbon monoxide poisoning in an apartment, understanding your legal rights is an important first step.

Your case. Your future. Our priority.

When Is a Landlord Liable for Carbon Monoxide Poisoning?

Landlords are not automatically responsible every time someone is exposed to carbon monoxide. Liability generally depends on whether the landlord acted negligently.

Examples of negligent conduct may include:

• Failing to install required carbon monoxide detectors
• Ignoring reports of malfunctioning detectors
• Failing to repair defective boilers or furnaces
• Improper maintenance of heating systems
• Defective ventilation
• Ignoring prior complaints about gas odors or equipment
• Failing to correct known building code violations

In many cases, the issue is whether the landlord knew or should have known about the dangerous condition and failed to take reasonable action.

Why Carbon Monoxide Is So Dangerous

Carbon monoxide replaces oxygen in the bloodstream, preventing organs from receiving the oxygen they need to function properly.

Because the gas has:

• No odor
• No color
• No taste

many victims do not realize they are being exposed until symptoms become severe.

The Centers for Disease Control and Prevention (CDC) estimates that more than 100,000 emergency department visits and over 14,000 hospitalizations occur annually in the United States due to unintentional, non-fire-related carbon monoxide poisoning. (cdc.gov)

Common Causes of Carbon Monoxide Exposure in Apartment Buildings

Carbon monoxide can accumulate when fuel-burning appliances are not properly installed, maintained, or ventilated.

Common sources include:

• Boilers
• Furnaces
• Water heaters
• Gas stoves
• Fireplaces
• Chimneys
• Portable generators used improperly
• Blocked flues
• Malfunctioning HVAC systems

Many of these hazards can be identified during routine inspections and maintenance.

Symptoms of Carbon Monoxide Poisoning

Symptoms often resemble the flu, making diagnosis difficult.

Common symptoms include:

• Headaches
• Dizziness
• Nausea
• Vomiting
• Fatigue
• Confusion
• Shortness of breath
• Chest pain
• Loss of consciousness

Prolonged exposure may lead to permanent neurological injury, brain damage, heart complications, or death.

If you suspect carbon monoxide exposure, leave the building immediately and call 911.

What Evidence Helps Prove a Carbon Monoxide Claim?

Premises liability claims involving carbon monoxide often require technical evidence.

Helpful evidence may include:

• Fire department reports
• Building inspection reports
• Carbon monoxide detector inspection records
• Maintenance records
• HVAC service records
• Building code violation history
• Medical records
• Emergency response documentation
• Witness statements
• Expert engineering evaluations

Early investigation can be especially important because defective equipment is often repaired or replaced after the incident.

What Should You Do After Carbon Monoxide Exposure?

If you believe you were exposed to carbon monoxide in your apartment:

• Leave the building immediately.
• Call 911 or your local emergency services.
• Seek medical evaluation, even if symptoms improve.
• Report the incident to your landlord or property manager.
• Preserve photographs of detectors or hazardous conditions, if it is safe to do so.
