Local Law 31 XRF lead testing: what NYC landlords need to do now

The August 2025 deadline has passed. Here’s what’s required and how to catch up.

Windsor Environmental · Updated November 2026

What the law requires

Local Law 31 of 2020 required XRF lead paint testing at the 0.5 mg/cm² action level of all rental units and common areas in pre-1960 buildings, plus 1960–1978 buildings where the owner knows of lead paint and rental units in 1–2 family homes, by August 9, 2025.

Who can test

An EPA-certified lead inspector or risk assessor, independent of the owner and of any company hired to do remediation.

Exemptions

  • Lead-free: all lead paint above 0.5 mg/cm² permanently removed. No annual notices or investigations needed.
  • Lead-safe: lead paint encapsulated or enclosed. Periodic inspections still required.

Owner-occupied co-op and condo units are not required to be tested while the owner lives there.

Penalties

Non-compliance can bring a Class C immediately hazardous violation, with civil penalties of $1,500 per unit or common area.

If you’re behind

  1. Schedule XRF testing for all covered units and common areas.
  2. Keep the reports. HPD can ask for them.
  3. Address positive components: maintain them lead-safe, or abate to work toward an exemption.

Questions

Is a 1.0 mg/cm² report still valid?

Older 1.0 reports may still count for compliance in some cases, but new exemptions require testing at 0.5 mg/cm².
