According to the NYC Department of Health and Mental Hygiene, Lead is a harmful metal that can cause serious health problems. Lead is especially dangerous for children and pregnant people, but it can harm anyone. Lead is often found in old paint. Lead paint, and the dust it turns into, is the most commonly identified source of childhood lead exposure in New York City. The most commonly identified sources of lead exposure for adults who work in the construction industry are job-related. Pregnant adults are more likely to be exposed to non-occupational sources of lead, such as certain consumer products found to contain lead. Some foods, spices, medicines, ceramic ware and cultural powders from areas around the world have been found to contain lead.
For decades, lead exposure has been disproportionately harming New York City’s most vulnerable communities, persisting as one of the city’s largest public health challenges. Guided by data and public health expertise, a recent report issued by the city of New York, Delivering on Commitment: The 2025 NYC Lead Compliance Report, outlines how the city has been working to eliminate this preventable crisis. This report details the city’s progress towards a lead free future under LeadFree NYC (2019), highlighting the current state of lead across the five boroughs and the remaining challenges on the path toward eliminating lead exposure for good.
Purpose of the Report
Delivering on Commitment: The 2025 NYC Lead Compliance Report takes a close look at the City’s progress toward eliminating lead exposure since the launch of LeadFreeNYC in 2019, an initiative to reduce childhood lead poisoning, expand protections, and tighten safety standards. It highlights what is working, where gaps remain, and what new strategies are needed to move faster.
The data also tells us a story: progress has not reached every neighborhood equally. Neighborhoods with pre-1960 housing are still disproportionately affected, tenant access barriers continue to slow inspections, and unsafe renovation practices still spread lead dust in occupied buildings. At the same time, one in five children misses required lead testing at ages one and two, even though early detection is essential for intervention. These disparities highlight why a citywide, cross-agency approach remains essential, and why eliminating lead exposure by 2029 requires sustained investment, updated laws, and deeper engagement with the communities most at risk.
LeadFree NYC
In 2019, the LeadFree NYC plan was released to eliminate childhood lead exposure and prevent lead poisoning in New York City, outlining a new goal to reduce child lead exposure to zero by 2029. Since its launch, City agencies and partner organizations have worked together to ensure the successful implementation of the 45 initiatives within the LeadFreeNYC plan. This city-wide initiative has strengthened enforcement tools, expanded protections in private housing and shelters, prioritized high-risk populations, and established steps towards reducing lead exposure in city-owned properties, consumer products, and water systems.
Key areas of concern:
Reduce elevated blood levels in children: The city’s primary goal with implementing LeadFree NYC is to strengthen efforts to prevent childhood lead poisoning and reduce elevated blood levels in young children.
Address lead based paint hazards: Those who live in older buildings with deteriorating paint are at higher risk of lead exposure. The effort to address these lead-based paint hazards involves creating stricter safety-standards, which includes extending Local Law 1 protections – a law that requires landlords to identify and repair lead paint hazards to single-family homes – enhancing inspector protocols, and auditing landlord compliance.
Address lead’s risk in consumer products: Imported foods, spices, remedies, cosmetics, and cultural items are common sources of lead exposure. This initiative permits the Health Department to broaden its monitoring and enforcement programs that track hazardous products, and requires shop owners to remove products that potentially contain lead from store shelves. If they fail to do so, they may face monetary penalties and are required to participate in training on identifying unsafe items to prevent future sales of these products.
Current State of Lead in NYC
New York City continues to face disproportionate lead risks because of its aging housing stock, older infrastructure, and densely populated conditions. In 2024 alone, 228,600 children were tested for lead, which is more than any other U.S. city. While NYC now maintains one of the lowest childhood lead poisoning rates among major cities, thousands of children are still affected each year, reinforcing that lead remains an ongoing public health concern.
To track exposure, the city relies on elevated blood lead levels (EBLLs), defined as a blood lead concentration of 3.5 µg/dL or higher. Although no amount of lead is considered safe, this threshold is used to flag cases where health officials must step in to identify and address the source of exposure. According to recent guidance from the U.S. Department of Health and Human Services (HHS), the Centers for Disease Control and Prevention (CDC), and the U.S. Department of Housing and Urban Development (HUD), children with blood lead levels of 3.5 µg/dL or higher are required to receive urgent health and environmental investigations.
Who is affected?
Children and pregnant individuals face the greatest risks from lead exposure. Children under six are especially susceptible, because their brains and nervous systems are still developing, making even low levels of lead exposure concerning.
Lead exposure can also harm pregnant individuals and developing fetuses. In 2024, over 285 pregnant people in NYC had EBLLs of 5 µg/dL or higher, primarily from imported consumer products. Most (86%) were foreign-born, from 26 countries including Mexico (52%), Ecuador (9%), Guatemala (7%), and India (7%).
What places are affected?
At the neighborhood level, EBLLs are most concentrated in areas with older housing infrastructure. These same areas also tend to have high testing rates, which means children in these neighborhoods are more likely to be identified, thus given the appropriate support. The borough distribution of lead-based paint violations reflects: Bronx (44%), Brooklyn (29%), Manhattan (15%), Queens (12%), Staten Island (1%).
Since the enactment of Local Law 1 of 2004, New York City has seen a steady and significant decline in children under six who have blood lead levels of 5 µg/dL or higher. However, risk is identified differently across agencies. HPD data is primarily driven by tenant complaints, which often come from high-density, multifamily housing, and may overlook lower-density neighborhoods where residents may be less likely or able to report issues. In contrast, DOHMH’s data is informed by childhood blood lead testing and captures risks in 1- to 2-family homes, households with recent travel or foreign-born residents, and areas where exposure may not be tied to housing complaints but to imported consumer goods, home remedies, or other less visible sources.
Continuing to Move the Needle
Today, the city is focused on finding the exact origins and causes of lead poisoning. To do so, the Mayor’s Office of Risk Management and Compliance, along with stakeholder agencies, have developed recommendations to keep us on the path towards zero cases of elevated blood levels and a lead-free future. These five recommendations are applied to the already existing strategies and standards New York City has set.
Next Steps
- Target high-risk sources: Increase inspections and remediation in older housing to protect vulnerable populations.
- Improve data sharing: Create a central platform to track blood lead levels, violations, and remediation, making information transparent and accessible.
- Update local laws: Modernize regulations to close gaps, require lead service line replacement, and strengthen enforcement.
- Engage residents: Offer flexible inspection schedules, multilingual outreach, and clear tenant rights information.
- Raise public awareness: Expand campaigns encouraging childhood lead testing and educating high-risk communities about health risks.
Conclusion
The 2025 NYC Lead Compliance Report makes one thing clear: New York City can reduce lead poisoning when the proper legislative actions are taken and when it commits the necessary resources to do so. Over the last 20 years, there has been a significant decline in elevated blood lead levels and lead poisoning incidents since Local Law 1 took effect in 2004, and the city saw even more progress since the establishment of the LeadFree NYC 2019 plan. However, progress does not mean the job is finished. Gaps still remain and the next steps involve a more specific and targeted approach to testing in areas known to be high-risk, which already face economic and housing insecurity. Testing and remediation are often costly, disruptive, and time-intensive, placing an unfair burden on tenants who may lack the money, time, or even temporary housing needed to stay safe. Closing these gaps is essential to ensuring that the city’s success in reducing lead exposure is shared by all New Yorkers, not just those with the resources to protect themselves.
