Lead-based paint was commonly used in U.S. housing until it was banned for residential use in 1978. That means any home or apartment building constructed before 1978 has a realistic chance of containing lead-based paint somewhere in its layers, even under newer paint — lead paint doesn't go away when it's painted over, it's just covered. A lead paint inspection answers a specific, narrower question than people often expect: is lead-based paint present on the tested surfaces, yes or no — not whether it's currently a hazard (that's a risk assessment) and not whether remediation worked (that's clearance testing).
Testing is typically done with an XRF (X-ray fluorescence) device, which reads paint layers directly on the surface without needing to remove a paint chip, or by collecting paint chip samples for lab analysis where XRF isn't practical. Either method identifies which tested components (windowsills, doors, trim, walls) contain lead-based paint and which don't, building a room-by-room or component-by-component picture rather than a single whole-building answer.
NYC has specific legal requirements around lead paint in multiple dwellings. Local Law 1 requires owners of multiple dwellings to identify and address lead-based paint hazards, generally presuming lead-based paint is present in buildings constructed before 1960 (extended to buildings from 1960 to 1978 where lead-based paint is known to be present), with particular obligations where a child under six resides in the unit. Local Law 31 strengthened these requirements further, including periodic inspection obligations. We test to inform compliance with these laws, not as a substitute for a landlord's or owner's own legal review of their specific obligations.
Signs you have a lead paint inspection problem
- Your building was constructed before 1978, or you're unsure of its construction date
- A child under six lives or will live in the unit, which triggers specific NYC legal obligations under Local Law 1
- You're a landlord needing to document compliance with NYC Local Law 1 or Local Law 31
- You're buying, selling or renting a pre-1978 property and want to know its lead-paint status before proceeding
- Paint is peeling, chipping or deteriorating on a surface in an older building
Why Manhattan sees this
NYC Local Law 1 presumes lead-based paint is present in multiple dwellings built before 1960 (extended to 1960–1978 where lead-based paint is known to exist), placing specific identification and remediation obligations on owners, with heightened requirements where a child under six lives in the unit.
Local Law 31 added further obligations to Local Law 1, including periodic inspection requirements for covered units — we test to the standard those legal frameworks expect, so documentation holds up for compliance purposes.
NYC's housing stock skews old — a large share of the city's multi-family buildings predate 1978 — which is why lead-paint inspection is a routine, not exceptional, part of pre-purchase and rental due diligence here.
