New York City Mold Exposure Lawyer
Mold does not announce itself. It grows behind walls, beneath flooring, inside ventilation systems, and above ceiling tiles, often for months before anyone realizes what has been making them sick. By the time a doctor connects the respiratory problems, chronic headaches, skin irritation, or cognitive symptoms to mold exposure, the damage to a person’s health can already be significant. For tenants in New York City apartments, employees in commercial buildings, and workers in construction or industrial settings, a New York City mold exposure lawyer can be the difference between bearing those costs alone and holding the responsible party accountable.
New York City’s housing stock and commercial building inventory make mold exposure a persistent problem. Older buildings throughout Manhattan, the Bronx, Brooklyn, and Queens carry decades of moisture intrusion, outdated plumbing, and deferred maintenance. When a landlord ignores a leaking pipe, a building manager lets water damage go unrepaired, or a contractor botches waterproofing on a renovation, mold follows. And under New York law, landlords and property owners carry legal duties to maintain habitable conditions. When they fail those duties and someone gets hurt, that failure can form the basis of a personal injury or premises liability claim.
Mold exposure cases sit at the intersection of medical science, building inspection, and civil liability. They require understanding which mold species cause the most serious health effects, how exposure levels are documented, what building codes and housing regulations required the property owner to do, and how to connect a plaintiff’s documented health conditions to the conditions in a specific building. Getting all of that right takes preparation, not guesswork.
How Mold Exposure Actually Causes Harm and Who Gets Sick
Not all mold is equally dangerous, and not all exposure leads to the same outcome. Some people develop relatively mild allergic reactions, sneezing, itchy eyes, and runny noses, that resolve once exposure ends. Others, particularly children, elderly individuals, people with asthma, and anyone with a compromised immune system, can develop serious respiratory illness, chronic sinus infections, or neurological symptoms from prolonged exposure to toxic mold species.
Stachybotrys chartarum, the mold species commonly called black mold, produces mycotoxins that have been associated with pulmonary hemorrhage in infants, severe respiratory distress, memory and cognitive impairment, and persistent fatigue in adults. Aspergillus and Penicillium species, while less dramatic in reputation, cause significant allergic and respiratory illness and are far more common in New York City residential buildings. Cladosporium and Alternaria species are frequent triggers for asthma attacks in children and adults who already have reactive airway disease.
For a legal claim to succeed, the connection between a specific mold species present in a specific location and a specific plaintiff’s documented medical condition must be established through evidence. That typically means environmental testing of the property, air quality sampling, industrial hygiene reports, and medical records tying the diagnosis timeline to the period of exposure. It also means demonstrating that the property owner knew or should have known about the moisture problem causing the mold and failed to address it in a reasonable time. New York City’s housing code places affirmative obligations on landlords to address water damage and mold conditions, and violations of those obligations create a paper trail that experienced mold exposure attorneys know how to use.
Liability Situations That NYC Mold Exposure Claims Commonly Involve
- Residential tenant claims against landlords: New York’s warranty of habitability requires landlords to keep rental units livable, and persistent mold growth generally violates that warranty. Tenants who report mold conditions in writing and receive no timely repair have documented the landlord’s notice and failure to act, two critical elements of a premises liability claim.
- Co-op and condominium building failures: In co-ops and condos across Manhattan and Brooklyn, responsibility for water intrusion often falls on the building’s board or management company. When a roof leak, facade failure, or common area plumbing problem causes mold in individual units, the building entity can bear liability for resulting health injuries.
- Workplace exposure claims: Office buildings, schools, healthcare facilities, and retail spaces with HVAC systems that recirculate mold spores can expose employees and visitors to dangerous levels over long periods. Workers who develop occupational illness from mold in a commercial building may have claims against building owners, property managers, or employers with control over maintenance decisions.
- Construction defect and contractor negligence: Improper waterproofing, faulty installation of roofing or window systems, and failures to properly dry out a structure after water damage can create conditions where mold grows within new or recently renovated construction. General contractors and subcontractors can face liability when their workmanship causes mold-related harm.
- Section 8 and public housing conditions: NYCHA housing developments throughout the five boroughs have been subject to significant scrutiny over mold and water damage conditions. Tenants in public housing who suffer health effects from documented mold conditions have legal avenues, though the procedural requirements for claims against a public entity differ from those against a private landlord.
- School and daycare building exposure: Children are among the most vulnerable to mold-related illness, and New York City school buildings, many of which are aging structures, have a documented history of mold problems. When a child develops respiratory illness traced to conditions in a school building, liability may rest with the New York City Department of Education or a private school operator depending on the institution.
- Mold disclosure failures in real estate transactions: Sellers and their agents who fail to disclose known mold conditions during a property sale can expose themselves to claims from buyers who discover mold after closing and sustain health or financial harm as a result.
What You Should Do If You Suspect Mold Has Harmed Your Health in New York City
The most important thing you can do immediately is see a doctor and make sure your symptoms are evaluated and documented. Tell your physician about your living or working environment, including any visible mold, musty odors, water stains, or a recent history of water damage in the building. Ask for a referral to a pulmonologist or allergist if your symptoms involve your respiratory system. Getting a diagnosis that connects your condition to environmental exposure is not just medically important, it becomes a foundational piece of any future legal claim.
At the same time, document the conditions in the building as thoroughly as you can. Photograph or video the visible mold, water staining, peeling paint, and any other evidence of moisture intrusion. Note the date and time of each photo. If you are a tenant, notify your landlord in writing, by certified mail or email so that you have a time-stamped record, describing the mold condition and requesting prompt remediation. Under New York City’s Housing Maintenance Code, landlords are required to address mold conditions, and their written response or failure to respond becomes part of your evidentiary record.
File a complaint with New York City’s Housing Preservation and Development (HPD) if your landlord fails to address the condition. HPD inspects and can issue violations, and those violation records are independently useful in a lawsuit. If the property is a commercial building or a workplace, you can file a complaint with the New York City Department of Buildings or with OSHA’s New York office, depending on the nature of the exposure. For NYCHA residents, complaints should be filed through the NYCHA Service Portal as well as through HPD.
Do not attempt to remediate large areas of mold yourself, both because it may affect your health further and because it can disturb the physical evidence of conditions before they are professionally documented. If environmental testing has not been done, a qualified industrial hygienist can take air samples and surface samples that become part of the case record. Keep all medical bills, prescription receipts, and records of time missed from work. New York personal injury claims have a statute of limitations, generally three years from the date of injury for most personal injury claims, though claims against public entities like NYCHA or the City of New York require a Notice of Claim to be filed within ninety days of the incident, making early legal consultation critical if a public entity is involved.
What the Cohan Law Firm Brings to a Mold Exposure Claim
Mold exposure cases are medically and technically demanding, and they require a firm that knows how to build a case from environmental data, medical records, and building code violations rather than relying on straightforward accident reconstruction. The Cohan Law Firm’s background in premises liability and personal injury throughout New York City gives the firm a foundation for handling exactly this kind of complex case. With over $100 million recovered for injured clients across Manhattan, Brooklyn, the Bronx, and Queens, the firm has the track record that matters when you are sitting across from an insurance carrier or a large property management company.
What clients consistently describe in their reviews is a firm that keeps them informed and treats them like people rather than case numbers.

The firm’s use of AI-powered legal technology to analyze evidence and identify patterns that insurers hope clients will miss is a meaningful advantage in cases where the documentary record is complex. Several of the firm’s attorneys are members of the Multi-Million Dollar Advocates Forum, a distinction requiring verified million-dollar results, and the team includes attorneys from large firm backgrounds alongside medical professionals who help assess the full scope of a client’s injuries from the beginning of the case.
For mold exposure clients who are already dealing with health problems and housing instability, the firm’s ability to handle consultations and retainer agreements digitally means you can move your case forward without adding more stress to an already difficult situation. The firm handles cases on a contingency basis, which means no legal fees unless compensation is recovered.
Questions About Mold Exposure Claims in New York City
Can I sue my landlord for mold in my New York City apartment?
Yes. New York landlords are required by law to maintain rental units in a habitable condition, which includes addressing water damage and mold growth. If your landlord knew about a mold condition, was given reasonable notice to fix it, and failed to do so, and if that failure caused you physical harm, you may have a valid premises liability claim for personal injuries as well as potentially a separate warranty of habitability claim for rent abatement or lease-related remedies.
What types of damages are available in a mold exposure lawsuit?
Depending on the facts of your case, recoverable damages can include medical expenses (past and future), lost wages from time missed at work, reduced earning capacity if your condition affects your ability to work long-term, pain and suffering, and costs associated with finding alternative housing during remediation. In cases where a landlord acted with particular disregard for tenant safety, additional damages may be available depending on the circumstances.
How do I prove that mold caused my health condition?
Proving causation in a mold case requires environmental evidence (testing showing the type and concentration of mold in the building), medical records connecting your diagnosis to environmental mold exposure, and often expert testimony from an industrial hygienist and a treating physician or specialist who can explain the causal link. The documentation timeline matters, meaning records showing when you first reported symptoms and when the mold was present carry significant weight.
How long do I have to file a mold exposure claim in New York?
For most personal injury claims in New York, the statute of limitations is three years from the date of injury. However, if your claim is against a public entity such as NYCHA or the City of New York, you must file a Notice of Claim within ninety days of the incident before you can pursue a lawsuit. Missing that ninety-day deadline can bar your claim entirely, which is why consulting with an attorney as early as possible is important if a public entity is potentially responsible.
What if I did not see visible mold but I was still getting sick?
Mold does not have to be visible to be present in harmful concentrations. Mold growing inside walls, beneath flooring, or within HVAC systems can cause significant air quality problems without any visible surface mold. Environmental air quality testing by a qualified industrial hygienist can detect mold spores and identify species even when the source is hidden. If your symptoms resolve when you leave the building and return when you are there, that pattern is itself meaningful clinical evidence worth documenting.
Can I bring a mold claim if I am a NYCHA tenant?
NYCHA tenants do have legal recourse for mold-related health injuries, but the procedural requirements differ from claims against private landlords. Claims against NYCHA, as a public authority, require a Notice of Claim to be filed within ninety days. NYCHA mold conditions have been extensively documented in inspection reports and federal oversight proceedings, which can provide supporting evidence. An attorney familiar with public housing liability in New York City can help you navigate the additional procedural requirements.
Does my renter’s insurance cover mold-related health claims?
Renter’s insurance policies typically cover personal property damage from certain sudden events but generally do not cover health injuries from mold exposure, and they rarely cover mold remediation costs unless the mold resulted from a covered peril like a burst pipe. Health injuries from mold are more appropriately pursued through a personal injury claim against the responsible property owner rather than through your own insurance policy.
What if my employer knew about mold in the office building and did nothing?
If your employer had control over the work environment and was aware of a mold condition that it failed to address, you may have claims under both the workers’ compensation system for occupational illness and potentially a separate tort claim against a third party, such as a building owner or property management company, that was responsible for building maintenance. New York’s workers’ compensation system generally bars direct suits against employers, but third-party liability claims against building owners or contractors are not barred by that system and can be pursued alongside a workers’ comp claim.
Can I withhold rent if my landlord refuses to fix a mold problem?
New York law does allow rent withholding under certain circumstances when a landlord has breached the warranty of habitability, but the mechanics matter. Simply stopping rent payment without following the appropriate legal procedure can expose you to eviction. The correct approach is generally to either pay rent into a court escrow account through a Housing Court proceeding, or to bring a warranty of habitability claim in Housing Court. An attorney can help you pursue the legal remedy correctly while also preserving any personal injury claim you may have for the health effects of the exposure.
Are mold exposure cases typically settled out of court?
Many personal injury cases, including mold exposure claims, resolve through settlement negotiations before reaching trial. However, the strength of the settlement you can obtain depends heavily on the quality of your documentation, expert support, and legal representation. Property owners and their insurance carriers will evaluate how well-prepared your case is before making a serious offer. Cases that go to litigation with strong environmental testing data, solid medical causation evidence, and documented notice to the landlord tend to produce better outcomes than cases that rely on informal reports and incomplete records.
