A lawsuit for lead poisoning is a civil claim against whoever caused the exposure — most often a landlord who ignored deteriorating paint, but also manufacturers of lead-containing products, water utilities, food companies, and employers. Who you sue, what you have to prove, and how long you have to file all depend on where the lead came from and the state you live in.
Who You Can Sue
The right defendant is the party whose conduct put the lead in front of the victim. In practice that falls into a handful of recurring categories.
Landlords and property owners. This is the largest category of lead poisoning litigation. The federal Residential Lead-Based Paint Hazard Reduction Act of 1992, known as Title X, requires anyone renting or selling housing built before 1978 to disclose known lead paint hazards, provide the EPA’s lead safety pamphlet, and include a lead warning in the lease. Under 42 U.S.C. § 4852d(b)(3), a landlord who “knowingly” violates these requirements is liable for triple the damages, and that standard does not require proof of willfulness or bad faith.
State and city rules often add more. Massachusetts requires landlords to remove or cover lead paint hazards in any pre-1978 home where a child under six lives, with correction required within 60 to 120 days of an order, and the landlord must pay reasonable moving expenses if deleading is necessary. Refusing to rent to families with young children because of abatement cost is illegal, and courts will presume retaliation if a landlord raises rent or moves to evict within six months of a written lead complaint. New York City’s Local Law 1 of 2004 requires landlords in pre-1960 buildings to survey annually for children under six and to inspect and remediate lead on chewable, friction, and impact surfaces. Failure to meet those obligations drives most New York lead paint cases.
Manufacturers. Companies that made and marketed lead paint for home use have been sued on a public nuisance theory. Ten California cities and counties sued Sherwin-Williams, ConAgra Grocery Products, and NL Industries in 2000; after a 2013 trial court ruling, a 2017 appellate decision narrowing the liability to pre-1951 homes, and the U.S. Supreme Court’s refusal to hear the appeal in October 2018, the case settled in July 2019 for $305 million. Los Angeles County alone received $133 million. The defendants did not admit liability.
Wisconsin took a different path. In Thomas v. Mallett (2005), the state Supreme Court applied the “risk-contribution theory” to let plaintiffs sue lead pigment manufacturers without identifying whose product caused the harm, apportioning liability by market share. Governor Scott Walker signed Act 2 in 2011 to eliminate that theory for claims arising after February 1, 2011. Because Wisconsin tolls the statute of limitations for minors until age 20, the last cohort able to sue under the older framework will age out around 2031.
Water utilities and the governments behind them. After Flint, Michigan, switched its water source in 2014 without adequate corrosion control, lead leached from aging pipes into the drinking water of roughly 100,000 residents. A $626 million civil settlement followed. By May 2026, more than 10,500 award letters had been issued for residential property claims, with payments having begun in December 2025. The court authorized partial payments for adult injury claims in March 2026, with distribution expected in June 2026. Minor and business claims are still being prepared. Children six or younger during the crisis receive the largest share, 64.5 percent.
The criminal track produced nothing. A one-person grand jury indicted nine current and former officials in 2021, including former Governor Rick Snyder, but the Michigan Supreme Court ruled the one-person grand jury process unauthorized under state law and declined to revive the charges in late 2023.
Food and product manufacturers and retailers. In October 2023, the FDA issued a public health alert after WanaBana Apple Cinnamon Fruit Puree pouches tested at roughly 200 to 300 times the recommended lead action level for baby food. WanaBana recalled nearly three million pouches; Schnucks and Weis brand cinnamon applesauce pouches were also recalled. Investigators traced the contamination to cinnamon processed in Ecuador, where lead chromate had apparently been added to the spice. By early 2024, the CDC had identified more than 500 lead poisoning cases across 44 states, 96 percent involving children under six. Parents sued WanaBana and Dollar Tree, which had received an FDA warning letter for failing to pull recalled product from shelves. WanaBana filed for bankruptcy in May 2024, listing $566,160 in assets. No centralized multidistrict litigation had been established for personal injury claims as of early 2024; cases were proceeding individually, with a separate class action covering consumer and medical monitoring claims.
Employers. Workers in battery manufacturing, construction, and demolition can be exposed on the job. OSHA sets a permissible exposure limit of 50 micrograms per cubic meter of air averaged over an eight-hour shift and requires engineering controls, protective equipment, and medical surveillance above the 30-microgram action level. Workers poisoned on the job generally pursue workers’ compensation, and in some cases separate suits against third parties such as equipment makers or property owners.
What You Have to Prove
In a premises liability lead paint case, the plaintiff generally has to show four things: lead was present at the property, the landlord knew or should have known, the landlord failed to act, and the exposure caused the harm. The evidence that carries those elements is largely documentary and medical: blood lead level test results, medical and school records showing developmental or cognitive injuries, inspection reports confirming lead in the unit, photographs of deteriorating paint, written complaints to the landlord, and records of the building’s age and compliance history. Medical and environmental experts tie the exposure to the specific injuries.
The underlying harm is well established. The CDC states that even low blood lead levels in a child can cause lasting damage to the brain and nervous system, lower IQ, learning and behavioral problems, slowed growth, and hearing and speech difficulties. Most poisoned children show no obvious symptoms, so blood testing is the only reliable way to detect exposure, and that testing becomes central evidence in any later lawsuit.
What Landlords Argue Back
Expect the defense to attack causation first. Landlords routinely argue the child was exposed somewhere else — a prior residence, a daycare, contaminated water, or soil — and retain medical experts to dispute the link between a given blood lead level and the claimed cognitive injuries, sometimes pointing to genetics or other environmental factors. They also raise lack-of-knowledge defenses, using inspection records, maintenance logs, and federal and local disclosure paperwork to argue they acted reasonably. Some jurisdictions let landlords argue tenants worsened the hazard through unauthorized renovations or by not reporting peeling paint, though New York law specifically prohibits comparative negligence claims against a child plaintiff.
What a Case Is Worth
Compensation can cover medical treatment, lost wages and diminished earning capacity, pain and suffering, loss of enjoyment of life, and, where the conduct is egregious, punitive damages. The number turns on the severity of the cognitive and developmental harm, the strength of the causation evidence, and the defendant’s assets or insurance.
The range is wide. In Baltimore, where lead paint litigation has been heavy, individual recoveries have run from as little as $1,500 to $18 million, with more than $300 million recovered collectively. A 2015 Baltimore jury awarded $9.3 million to Terrance Smith Jr. for alleged childhood exposure in a rowhouse, though the noneconomic portion was subject to Maryland’s statutory cap. A single New York firm reported verdicts including $58 million for one child’s cognitive and physical disabilities and $21 million for three siblings. Michigan settlements for children poisoned by lead paint have ranged from roughly $390,000 to $1.4 million. Most cases settle before trial.
How Long You Have to File
Every lead poisoning lawsuit runs on a state deadline. For personal injury, 28 states use a two-year statute of limitations and 12 states allow three years. Maine and North Dakota give plaintiffs up to six years; Tennessee allows only one.
Because most victims are young children, the tolling rules for minors are usually what matters. In many states the clock does not start until the child turns 18. In California, Texas, and Nevada, the two-year period begins at 18, making the deadline the 20th birthday. In New York, the three-year period begins at 18, giving plaintiffs until age 21. Massachusetts also allows filing until age 21. Missing the deadline bars an otherwise strong claim, so the state-by-state variation is worth confirming with a lawyer early.
Class Actions and Individual Suits
Class actions are available when many people are harmed by a common source, such as a contaminated municipal water system or a recalled consumer product. Individual lawsuits remain more common where exposure traces to a specific property. The two tracks can run in parallel: in the WanaBana matter, individual personal injury suits were filed in various jurisdictions while a separate class action pursued consumer and medical monitoring claims.
