Lead Dust Wipe Testing NYC
Certified Lead Dust Wipe Testing & Clearance Inspections Across New York City
When is Lead Dust Wipe Testing Required in NYC?
Lead dust wipe testing NYC is required any time renovation, repair, or painting (RRP) work disturbs lead-based paint in a pre-1978 building. In New York City, the rules go further than federal EPA standards — NYC Local Law 31 of 2020 and NYC Health Code Article 11 impose strict testing obligations on landlords and contractors working in residential buildings.
Specifically, lead dust wipe testing is legally mandated in the following situations:
- After any RRP work in pre-1978 buildings with children under 6 present
- After HPD-ordered lead paint violation corrections
- Before a unit is re-occupied following lead remediation work
- As part of NYC Local Law 31 XRF inspection follow-up when lead paint is disturbed
- After construction or renovation in any NYC pre-1978 residential unit
Skipping clearance testing before re-occupancy can expose landlords to HPD violations, DOH penalties, and serious legal liability if a child is harmed.
What is Lead Dust Clearance Testing?
Lead dust clearance testing is a post-work inspection performed by a certified Lead Inspector or Risk Assessor to confirm that renovation or remediation work has not left dangerous levels of lead dust on surfaces — floors, window sills, and window troughs are the primary focus areas.
Here's exactly how the clearance process works:
- Visual inspection: Confirm all work is complete, containment removed, and area cleaned before sampling
- Wipe sample collection: Certified inspector collects dust wipe samples from defined surface areas using standardized methods
- Lab analysis: Samples sent to NVLAP-accredited laboratory; results in 24–72 hours
- Pass/fail determination: Results compared to EPA and NYC HUD clearance standards (e.g., floors ≤ 10 µg/ft²)
- Clearance report issued: Written report documents all sample locations, results, and pass/fail status
- Re-cleaning if needed: If samples fail, area must be re-cleaned and re-tested before occupancy
Only a certified Lead Inspector or Risk Assessor can perform and certify clearance testing in NYC — not the contractor who did the work.
