Do I have to prove my landlord knew there was lead paint?

In a pre-1960 New York City multiple dwelling, generally no. Local Law 1 of 2004 requires owners to presume that paint in buildings built before 1960 is lead-based paint, and it extends that presumption to buildings from 1960 to 1978 where the owner knows lead paint is present. Once a child under six resides in the unit for ten or more hours a week, the duties to give annual notice, inspect annually, and remediate hazards attach whether or not anyone reported anything.

How long do we have to bring a lead poisoning claim for a child in New York?

Longer than most families expect. CPLR § 208 tolls the limitations period during infancy, and the ten year ceiling in that section applies by its terms to medical, dental, and podiatric malpractice rather than to an ordinary injury claim. A lead exposure claim against a private landlord is an ordinary injury claim, so the three years generally begins running at age 18, placing the outside deadline near the twenty-first birthday. If the building is public housing or another public entity, a 90-day notice of claim requirement changes the analysis completely.

What blood lead level triggers a New York City investigation?

3.5 micrograms per deciliter. The Department of Health and Mental Hygiene lowered the intervention level from 5 to 3.5 in March 2022 to match the federal reference value, and the Board of Health codified it in the Health Code in October 2022. On a report of a child under 18 at or above that level, the Department investigates to identify sources, including inspecting the child's dwelling unit and other addresses where the child spends significant time, and orders abatement where it finds a hazard.

My landlord offered to repaint the peeling areas. Should I agree?

Not without lead-safe work practices and containment, and not before the condition is documented. Sanding, scraping, and painting over lead-based paint without containment can release far more dust than the peeling paint was releasing, and doing it in an occupied apartment with a young child present is how short-term severe exposures happen. It also destroys the condition as it existed. Photograph everything first, file a 311 complaint, and insist the work be done by a certified firm.

What evidence proves the exposure harmed my child?

Blood lead results establish exposure and dose. What establishes harm is neuropsychological testing, measured against the child's own family and educational baseline, together with school records, early intervention or special education files, developmental evaluations, and teacher observations. Those materials are what an economist later uses to project lost earning capacity, which is usually the largest component of a childhood lead case.

We have moved out of the apartment. Can we still bring a claim?

Yes. The claim belongs to the child and arises from the exposure that occurred while you lived there, not from your current address. Moving makes documentation harder rather than impossible, which is why the Health Department's inspection file, HPD violation history, 311 records, and any photographs taken inside the apartment during the exposure period become that much more important. Prior owners remain defendants for the period they owned the building.

Can You Sue a New York City Landlord for a Child's Lead Poisoning?

Yes. New York City wrote the landlord's duty into law, and it does not depend on the landlord being told there was lead paint.

Local Law 1 of 2004 presumes that paint in a building put up before 1960 is lead-based paint. Where a child under six lives in the apartment, the owner has to inspect annually, keep the paint intact, and remediate hazards.

An owner who did none of that is not defending a case about what it knew. It is defending a case about a presumption it never rebutted.

There is also a timing point families are rarely told. A child's injury claim in New York is tolled during infancy, so it generally remains available until the child turns 21.

What Local Law 1 of 2004 Requires of a New York City Landlord

New York City's lead law is unusual among American cities because it puts the burden on the owner rather than on the family, and it does so through a presumption.

Owners of multiple dwellings built before 1960 must presume the paint is lead-based paint. The presumption extends to buildings put up between January 1, 1960 and January 1, 1978 where the owner knows lead-based paint is present. The obligations attach where a child under six resides in the unit for ten or more hours a week.^[1]

What the owner has to do:

Send an annual notice asking whether a child under six lives in the apartment, and follow up when no response comes back.
Inspect the unit annually where a young child resides, looking for peeling paint and other lead hazards.
Remediate chipped and peeling paint using safe work practices, by trained workers, with containment.
Perform turnover work between tenants, including complete removal of lead-based paint from door frames and window sills and other friction and impact surfaces.
Keep records for ten years of notices, inspections, and work performed.
Certify the turnover work to the incoming tenant with the new lease.

Every one of those is a document that either exists or does not, which is the single most useful feature of this law for an injured child's case. A landlord that cannot produce ten years of annual notices and inspection records is not arguing about reasonableness; it is arguing about why the file is empty.

The Records That Decide a New York Lead Case

Lead cases are unusually document-heavy, and the good news for families is that most of the documents are generated by agencies rather than by the landlord.

On the health side: the child's blood lead test results with dates and values, pediatric records, developmental and neuropsychological evaluations, and early intervention or school special education records. On the housing side: the Health Department's environmental investigation and inspection report for the apartment, any order to abate, HPD violation history for the unit and the building, 311 complaint history, and any Department of Buildings permits showing renovation work.

From the landlord, in discovery: the annual notices and the responses, the annual inspection records, work orders and repair invoices, turnover certifications, the lead-safe training credentials of anyone who did the work, and the ten years of records the law says must be kept.

Photographs matter too, and families usually have them without realizing it. Birthday and holiday pictures taken in the apartment during the exposure period frequently show the condition of the window wells, the door frames, and the walls better than any later inspection can reconstruct.

How New York City Responds to an Elevated Blood Lead Level

The City's public health response creates the evidentiary record that a private claim is later built from, so it is worth understanding what it produces.

The 3.5 Threshold, and What It Triggers

In March 2022 the New York City Department of Health and Mental Hygiene lowered the blood lead level for intervention from 5 to 3.5 micrograms per deciliter, matching the federal reference value, and the Board of Health codified that level in the Health Code in October 2022. Where a report is made of a child under 18 with a blood lead level at or above 3.5, the Department conducts an investigation to identify sources, including inspection of the dwelling unit where the child resides and any supplemental address where the child spends significant time.^[2]

Where the Department finds a lead-based paint hazard because of the condition, location, or accessibility of the paint to children, it orders abatement. For a family, that inspection report and any resulting order are the documents that convert a suspicion into a proved hazard, dated, at an address, by a government agency that had no stake in the litigation.

Which is why the first instruction for any family with an elevated result is to request the Health Department's investigation file for the apartment. It exists whether or not anybody has decided to bring a claim.

Where the Lead Actually Comes From in a New York Apartment

Intact painted walls are usually not the problem. Friction, impact, and disturbance are.

Windows and Window Wells

The single most common source. A double-hung window grinds paint into dust every time it is opened, and the dust collects in the well at exactly the height a toddler stands.

Door Frames, Doors, and Jambs

Friction surfaces that shed with every use, which is why the law requires complete removal from these surfaces at turnover rather than repainting.

Peeling and Chipping Walls and Ceilings

Especially where a chronic leak has been softening the plaster for years. Water damage and lead hazards travel together, and a leak complaint history is often the best proof of both.

Renovation Without Containment

Sanding, scraping, and demolition in an occupied pre-1960 apartment can produce a severe short-term exposure. Federal renovation, repair, and painting rules require certified firms and lead-safe work practices in target housing, and a landlord who used an unqualified contractor has a distinct failure to answer for.

Radiators, Railings, and Painted Metal

Heat and abrasion both release paint, and painted radiators sit at floor level.

Soil, Dust Tracked In, and Common Areas

Hallways, stairwells, and building entries in older buildings, plus exterior paint from window frames and fire escapes that settles into the ground outside.

A Child's Claim Stays Open Until 21

Families are frequently told, or assume, that the three year deadline ran while their child was small. In an ordinary injury case that is wrong.

CPLR § 208 tolls the limitations period during infancy, and the ten year ceiling written into that section applies by its terms to actions for medical, dental, or podiatric malpractice. A child's ordinary personal injury claim, which is what a lead exposure claim against a landlord is, is not subject to that ceiling.^[3] Where the ceiling does apply, and how it cuts a family off, is on our page about the ten-year cap on a child's malpractice claim.

The practical result is that the three years generally begins to run when the child turns 18, which puts the outside deadline around the twenty-first birthday. Every other New York injury filing deadline is measured from the date of the injury itself.

Two cautions. If the building is owned by the New York City Housing Authority or another public entity, a notice of claim requirement applies and the timing analysis is completely different and far shorter. And waiting is still bad strategy, because the apartment gets repainted, the family moves, the landlord sells the building, and the neuropsychological picture is easier to attribute the closer the testing sits to the exposure.

What Lead Exposure Does to a Developing Child

The reason these cases carry the value they do is that the harm is permanent and it lands on a person who has not started school yet.

Cognitive effects. Reduced IQ, impaired attention and executive function, and slower processing speed. The effects are dose-related and there is no established safe blood lead level in children.
Learning disability and academic impact. Reading and math difficulty, grade retention, and special education placement.
Behavioral and emotional effects. Attention deficits, impulsivity, irritability, and aggression.
Speech and language delay. Frequently the first thing a parent notices and the reason a pediatrician orders testing.
Motor and coordination difficulty. Fine motor delay in particular.
Growth, hearing, and hematologic effects. Including anemia at higher exposures.
Severe acute poisoning. Rare at current levels, but encephalopathy, seizures, and death remain possible at the highest exposures.

Proof comes from neuropsychological testing rather than from the blood values alone. Blood lead levels establish exposure and dose; testing establishes what the exposure cost this particular child, measured against their own family and educational baseline.

If Your Child Just Tested High

Five steps, in roughly this order, and the first two are medical rather than legal.

Follow the pediatrician's guidance on confirmatory testing and follow-up, and have any other young children in the household tested as well. Ask the pediatrician for a developmental screening rather than waiting to see how school goes.

Report the condition of the apartment to the landlord in writing and keep a copy, then file a 311 complaint so the report exists in the City's system with a date on it. Do not accept an offer to have the super repaint the area, because repainting over a hazard without containment can make the exposure worse and it destroys the condition as it existed.

Photograph the peeling paint, the window wells, the door frames, and any water damage, room by room. Then request the Health Department's environmental investigation file and the building's HPD violation history, both of which are obtainable and neither of which the landlord controls.

Who Can Be Held Responsible in a New York Lead Poisoning Case

The owner is the primary defendant, and rarely the only one. The same statutory duty analysis, and frequently the same managing agent, runs a carbon monoxide poisoning claim against a New York landlord.

The building owner. Under Local Law 1's inspection, remediation, turnover, and record-keeping duties, and under the general duty to keep the premises in good repair.
The managing agent. Where an agent handled complaints, repairs, and turnover work.
A prior owner. Where the exposure period spans a sale, the owner during that period remains a defendant for what happened on its watch.
A renovation contractor. Where uncontained sanding, scraping, or demolition in an occupied apartment caused the exposure.
The New York City Housing Authority. Where the apartment is public housing, on a 90-day notice of claim track. Our page on public housing injury claims covers those requirements.

Where a landlord argues it never knew, the presumption is the answer. Local Law 1 does not ask an owner of a pre-1960 building whether it knew there was lead paint. It tells the owner to assume there is and to act accordingly.

What a Child's Lead Poisoning Claim Can Recover

New York places no cap on compensatory damages, and in a childhood lead case the largest components sit decades in the future.

Past and future medical and evaluation costs. Testing, monitoring, neuropsychological evaluation, and treatment.
Educational and therapeutic services. Tutoring, special education support, speech and occupational therapy, and behavioral services.
Lost future earning capacity. Usually the largest number in the case, projected from the measured cognitive deficit against the child's expected educational and occupational path.
Pain and suffering. Including loss of enjoyment of life and the effect on the child's ability to participate in ordinary childhood.
Future care and support services. Where the deficit requires supervision or assistance into adulthood.
A parent's derivative claim. For the costs and services a parent has borne.

Because a minor's recovery is involved, New York requires court approval of a settlement and the funds are protected for the child. That process is routine, and it is one of the reasons these cases are handled differently from an adult claim from the outset.

Why Families Bring Lead Poisoning Cases to Lawsuit Legal

Parents usually arrive with a blood test result and no idea that the law already put this on the landlord.

The lawyer other lawyers call. Don Worley built that reputation representing high-impact, high-stakes cases for the seriously injured and surviving family.
The agency file comes first. The Health Department's environmental investigation, any order to abate, and the building's HPD violation and 311 history, because those are dated findings by a neutral party.
The ten year record demand. Annual notices, annual inspections, turnover certifications, and training credentials, which the law requires the owner to have kept.
The child's baseline gets established properly. Neuropsychological testing measured against the family and educational baseline, because the deficit rather than the blood value is what a jury is asked to compensate.
We prepare every case as though a jury will decide it. That is what moves an adjuster's number months before a trial date exists.
Volume where it helps, restraint where it counts. Over 40,000 cases handled and $100 million recovered, that's deep experience with selective case acceptance, so our experience, time, and resources are fully invested in securing the strongest outcome for every client we represent.

A High Lead Result Is the Beginning of the Record, Not the End of the Story

Apartments get repainted, families move, and buildings change hands, and each of those makes the condition harder to prove later.

Children living in New York City apartments deserve windows that are not grinding lead into dust, annual inspections that actually happen, and turnover work done the way the law describes rather than a coat of paint over the problem. A lead result is a number on a page. What it costs a child turns up years later in a classroom, and a claim has to be built to cover that. Lawsuit Legal handles the landlord. You look after your child.

We help parents, grandparents, and guardians of children exposed to lead in rental housing, with the legal help they need to hold a building owner to duties New York City already wrote down. Call (888) 713-6653 whenever you are ready. A review of your child's exposure is free and confidential.
