Local Law 111 Clearance Requirements

When dust wipe testing is required and how to achieve clearance.

Critical Requirement

Tenants cannot re-occupy a unit after renovation work in a pre-1960 building until dust wipe clearance is achieved. Allowing re-occupancy without clearance is a Class C violation with penalties up to $5,000.

When Is Dust Wipe Testing Required?

Local Law 111 requires dust wipe clearance testing after any renovation, repair, or painting work in a pre-1960 building that disturbs painted surfaces:

  • More than 2 square feet of interior painted surfaces
  • More than 20 square feet of exterior painted surfaces
  • Work includes painting, sanding, scraping, demolition, or window replacement
  • Applies to all pre-1960 buildings, regardless of known lead paint presence

Clearance Standards

To pass clearance, lead dust levels must meet NYC's strict standards:

≤10

μg/ft² on Floors

≤50

μg/ft² on Window Sills

≤100

μg/ft² on Window Troughs

Our Dust Wipe Clearance Process

EPA-certified sampling with NYS ELAP laboratory analysis.

1

Site Preparation Check

Before sampling, we verify that work is complete, debris has been removed, and the unit has been cleaned. Sampling can only occur after final cleanup.

2

EPA-Approved Dust Sampling

Our EPA-certified technicians collect dust wipe samples from floors, window sills, and window troughs using standardized sampling protocols. Each wipe is individually sealed and labeled for laboratory analysis.

3

NYS ELAP Lab Analysis

Samples are sent to a New York State ELAP-certified laboratory for lead content analysis. Lab results are typically available within 3-5 business days.

4

Clearance Report & HPD Filing

You receive a comprehensive lab report with pass/fail determination. If clearance is achieved, we assist with HPD filing so tenants can re-occupy. If failed, we provide re-cleaning and re-testing recommendations.

What Happens If Clearance Fails?

If any dust wipe sample exceeds clearance standards, additional cleaning and re-testing are required before tenants can re-occupy.

Re-Cleaning Protocol

  1. HEPA vacuum all surfaces (floors, window sills, troughs)
  2. Wet-mop or wet-wipe all surfaces with lead-specific detergent
  3. Rinse with clean water
  4. Allow surfaces to dry completely
  5. Re-test with new dust wipe samples

Note: Re-testing after failed clearance typically requires 24-48 hours for cleaning and drying before new samples can be collected. Budget time accordingly to avoid tenant displacement.
