XRF Lead Testing Near Me: NYC Local Law 31 & What to Expect

Last updated: May 2026 If you’re a NYC landlord or property manager searching for XRF lead testing near you, the underlying question is usually about Local Law 31 of 2020 compliance. The law required XRF lead-based paint inspections of all dwelling units in pre-1960 NYC rental buildings (and pre-1978 buildings where lead is known to exist) by August 9, 2025. Buildings that missed that deadline are now facing HPD enforcement, and buildings with new tenants with children under 6 face one-year inspection deadlines from move-in. The window for “we’ll get to it” has closed. UNYSE has been performing XRF lead testing across NYC since 1993. We’re EPA-certified lead inspectors with handheld XRF analyzers calibrated to the current 0.5 mg/cm² action level, and we handle the HPD-required documentation as part of the inspection. This guide covers what XRF lead testing actually involves, what it costs in NYC, what Local Law 31 specifically requires, and how to evaluate inspection providers given the regulatory environment.

What XRF Lead Testing Is and How It Works

XRF stands for X-Ray Fluorescence. It’s a non-destructive testing technology that identifies the elemental composition of materials by directing X-ray energy at a surface and measuring the energy emitted back. For lead paint testing specifically, a handheld XRF analyzer measures lead concentration in paint coatings, through multiple layers, including topcoats applied over historical lead paint. The practical advantages over paint chip sampling:

• Non-destructive. No surfaces are damaged. No paint is removed. The wall, trim, or door looks the same after the test as before.
• Fast. Each measurement takes 5 to 10 seconds. An experienced inspector can test 40 to 60 surfaces per hour.
• Penetrates through layers. XRF detects lead even if it’s buried under decades of newer paint. Paint chip sampling only tests the layers extracted in the sample.
• Real-time results. Inspectors see readings during the inspection, which informs whether additional sampling or specific surfaces require attention.

The technology has been the standard for lead paint inspection in NYC since the regulatory framework was established. NYC HPD specifically requires XRF testing under Local Law 31, paint chip sampling is only acceptable for resolving inconclusive XRF readings or testing surfaces too damaged for XRF measurement.

Why XRF Lead Testing Is Required in NYC: Local Law 31

Local Law 31 of 2020 expanded NYC’s lead paint inspection requirements significantly:

• Applies to pre-1960 rental buildings (or pre-1978 buildings where lead is known to exist).
• Required XRF inspections of all dwelling units and common areas by August 9, 2025, OR within one year of a child under 6 routinely spending 10+ hours per week in a unit.
• Common areas (hallways, stairwells, lobbies, laundry rooms) were added to the requirement under Local Law 111 of 2023, effective June 2024.
• Inspector must be EPA-certified and independent of any abatement firm hired for remediation.
• Records must be maintained for 10 years.
• HPD-defined lead-based paint threshold is currently 0.5 mg/cm² (lowered from 1.0 mg/cm² effective December 1, 2021).

For buildings that missed the August 9, 2025 deadline, HPD enforcement is active. Violations carry fines from $250 to $40,000 depending on type and pattern. The strategic move for owners of pre-1960 NYC rental buildings who haven’t yet completed Local Law 31 testing is to schedule inspection now rather than wait for the violation notice. For buildings that have completed Local Law 31 testing, ongoing requirements include:

• Annual notice to tenants regarding lead paint hazards (HPD Form LEAD-PEH-1)
• Re-inspection when tenants change or when conditions change
• Repeat XRF testing required if positive findings remain unabated
• Lead-Free or Lead-Safe exemption applications are an option if no lead is found

UNYSE handles the inspection, the HPD-required documentation, and exemption application support as part of our standard service.

XRF Lead Testing Cost in NYC

XRF lead testing in NYC typically costs $400 to $1,200 per dwelling unit, with most residential inspections falling in the $500 to $800 range. Common-area testing under Local Law 111 is typically priced separately.

Inspection Type	NYC Cost Range	What’s Included
Single residential unit	$400–$1,200	XRF testing all painted surfaces, written report, HPD documentation
Small multi-unit building (2–4 units + common)	$1,200–$3,500	Per-unit testing + common area testing
Mid-size multifamily (5–20 units)	$2,500–$8,000	Per-unit pricing typically declines with volume
Large multifamily (20+ units)	$200–$400 per unit + common	Volume pricing applies
Lead-Free exemption application	$300–$800 additional	Full unit testing + exemption filing support
Lead-Safe exemption application	$300–$800 additional	Reduced testing for units meeting Lead-Safe criteria
HPD violation response testing	$500–$1,500 per unit	Includes XRF + abatement coordination documentation

Pricing varies by building access, unit size, number of painted surfaces, scheduling requirements, and whether common-area testing is included. Manhattan pricing typically runs 10–20% above outer borough pricing because of access, parking, and labor scale. Volume discounts apply for multi-unit buildings. What’s typically included: XRF testing of every painted surface in the unit (walls, doors, door frames, window sills, trim, baseboards, ceilings, radiators, built-in furniture), photo documentation, written report identifying each tested surface with its measurement, HPD-required forms, and lab work for any inconclusive XRF readings that require paint chip backup. What’s usually NOT included: lead abatement (if needed, separate scope by a different firm), HPD violation response beyond inspection documentation, dust wipe clearance testing after abatement, exterior testing of building facade or non-residential areas.

The Inspection Process: What Happens On-Site

A typical XRF lead inspection of a NYC residential unit takes 1 to 3 hours on-site depending on unit size and number of painted surfaces. Here’s what to expect: Pre-visit coordination. Tenant notification (required if occupied), scheduling, and confirming access to all rooms including closets and bathrooms. For Local Law 31 compliance, common areas and all dwelling units must be tested, not just sample units. Equipment setup. The inspector arrives with handheld XRF equipment, recordkeeping materials, and identification confirming EPA certification. The XRF unit is calibrated to 0.5 mg/cm² per HUD’s Performance Characteristic Sheet (PCS) for the model in use. Surface-by-surface testing. The inspector places the XRF analyzer directly on each painted surface and takes a reading. Walls, doors, door frames, window sashes, window sills, window jambs, trim, baseboards, ceilings, radiators, casings, built-ins. Each measurement is documented with location, surface, color, condition, and reading. Inconclusive readings. Some XRF readings fall in an inconclusive range per the manufacturer’s PCS (typically around 0.5 mg/cm²). For these, paint chip samples are collected and submitted for laboratory analysis. Results return in 2 to 5 business days. Report preparation. The inspector compiles findings into a written report with:

• Inspector name and EPA certification number
• Building and unit identification
• All tested surfaces with measurements and classifications
• Photo documentation
• HPD-required disclosures and forms
• Recommendations for any positive findings

For Local Law 31 documentation, the report is the basis for HPD recordkeeping. For exemption applications (Lead-Free or Lead-Safe), the report supports the application package.

What Happens If Lead Is Found

A positive XRF reading at or above 0.5 mg/cm² is classified as lead-based paint by HPD. What happens next depends on whether the paint is peeling and whether a child under 6 resides in the unit. Intact lead paint (not peeling, not damaged). No immediate abatement is required. The paint must be monitored, maintained, and addressed if it deteriorates. The unit cannot apply for Lead-Free exemption (which requires zero lead), but may qualify for Lead-Safe exemption if conditions meet criteria. Peeling lead paint with no child under 6. Repair using lead-safe work practices is required. The work must be performed by an EPA-certified lead renovator (RRP) or a NYS-licensed lead abatement contractor depending on scope. Repair, not abatement, is acceptable for non-occupied or no-child-resident scenarios. Peeling lead paint with a child under 6 in the unit. HPD enforcement applies. The owner has typically 21 days to abate the hazard under HPD’s emergency lead protocol. Abatement must be performed by a licensed abatement contractor with post-abatement dust wipe clearance testing required. HPD violation issued. The violation specifies the affected surfaces, the deadline for correction, and the documentation required for closeout. Property owners have the right to contest violations through HPD’s process, and the December 2021 rule change allowing contest of certain violations using paint chip analysis (when XRF reading is between 0.5 and 0.6 mg/cm²) provides some procedural options. UNYSE coordinates between inspection findings and licensed abatement contractors when remediation is needed. We don’t perform the abatement ourselves on projects where we’ll do clearance testing, the conflict rule applies here, too. Post-abatement clearance dust wipe testing is required by HPD to close out lead-based paint violations.

Choosing an XRF Inspector: What Actually Matters

NYC has many XRF lead inspection providers. Most claim “EPA certified” and “Local Law 31 ready.” Here’s what actually differentiates them when you’re choosing: 1. EPA certification status. Verify the inspector holds active EPA Lead Inspector or Risk Assessor certification, both authorize XRF testing under Local Law 31. The certification number is publicly verifiable through EPA’s Lead-Safe Certified Firm Locator. 2. XRF instrument model on the HUD PCS list. The handheld XRF must be on the HUD-approved Performance Characteristic Sheet list and calibrated to 0.5 mg/cm². Models from SciAps, Niton, Olympus, Viken, Heuresis, and others are typically approved, but the specific model and settings matter. 3. Independence from abatement. Under NYS regulatory framework and Local Law 31 requirements, the inspector must be independent of any abatement firm hired for the building’s lead work. Firms that offer both inspection and abatement under one roof present compliance issues. 4. NYC experience specifically. Local Law 31 compliance differs from general lead inspection work in other markets. Inspectors with limited NYC experience may miss HPD-specific documentation requirements, exemption application opportunities, or violation response nuances. 5. Report quality. Request a sample report before engaging. Reports should include per-surface measurements (not just summaries), photo documentation, HPD-required forms, and clear classification of each surface as positive, negative, or inconclusive. 6. Turnaround commitment. Stated business days for delivery of the written report, not “we’ll get back to you.” A reasonable benchmark for residential XRF inspection: report delivered within 5 to 7 business days of on-site inspection. 7. Transparent pricing. Per-unit pricing or stated ranges with variables explained. Quotes that require a “free estimate visit” before pricing is provided tend to produce surprise scope changes later. UNYSE meets all of these standards, and we publish our typical price ranges because we believe property owners should be able to budget the work without a sales call. We also follow the inspector-abatement independence rule strictly, which means we coordinate with licensed abatement contractors when remediation is needed rather than performing the work ourselves.

Frequently Asked Questions

How long does an XRF lead inspection take?

A typical NYC residential unit inspection takes 1 to 3 hours on-site, depending on unit size and number of painted surfaces. A studio or small one-bedroom might be 1 hour; a large multi-bedroom unit with extensive trim and built-ins might be 3 hours. The written report typically takes 5 to 7 business days to deliver, with rush turnaround available for transactions or compliance deadlines.

Does Local Law 31 apply to my building?

Local Law 31 applies if your building is a rental building (one or more units rented to non-owner-occupants) constructed before 1960, OR if your building is constructed between 1960 and 1978 AND you know lead-based paint is present. The law also extends to certain 1-2 family buildings where the owner does not reside, under Local Law 111 of 2023. If you’re unsure whether your building is covered, the UNYSE intake team can confirm based on building age and use.

What if my XRF inspection finds lead paint?

A positive finding does not automatically mean abatement. If the lead paint is intact (not peeling, not damaged), no immediate abatement is required, though the surface must be monitored and addressed if it deteriorates. If the paint is peeling and a child under 6 resides in the unit, HPD’s emergency lead protocol applies and abatement is required. The full implications depend on each surface’s condition and the unit’s occupancy. Your inspection report will identify each finding with the specifics.

Can I apply for a Lead-Free exemption after XRF inspection?

Yes, if your XRF inspection shows zero positive lead readings across all dwelling units and common areas, you can apply for a Lead-Free exemption under HPD’s program. The exemption removes the annual notice and re-inspection requirements that otherwise apply under Local Law 31. The application requires the full inspection report plus HPD’s application package. UNYSE supports Lead-Free and Lead-Safe exemption applications as part of standard service.

How much does XRF lead testing cost for a whole building?

Whole-building XRF testing cost depends primarily on number of dwelling units, common-area size, and unit accessibility. As a general benchmark: small buildings (2–4 units) typically run $1,200–$3,500 total; mid-size buildings (5–20 units) typically run $2,500–$8,000 total; larger buildings (20+ units) typically run $200–$400 per unit plus common areas. Volume discounts apply for larger properties. We provide written per-property quotes after confirming building size and scope.

Is paint chip testing acceptable as a substitute for XRF?

No, not under Local Law 31. HPD requires XRF testing as the primary method for Local Law 31 compliance. Paint chip lab analysis is only acceptable for resolving inconclusive XRF readings (typically in the 0.4–0.6 mg/cm² range per the manufacturer’s PCS) or for testing surfaces where XRF measurement is not possible due to damage or geometry. The inspection must be XRF-led.

What if I get an HPD lead paint violation?

If you’ve received an HPD lead-based paint violation, the response steps are: review the violation specifics, schedule XRF inspection to document current conditions, engage a licensed abatement contractor if positive findings require remediation, complete abatement under containment with post-abatement dust wipe clearance testing, and submit clearance documentation to HPD for violation closeout. UNYSE handles the inspection and clearance testing components and coordinates with abatement contractors. Timeline from inspection to violation closeout is typically 3 to 6 weeks depending on abatement scope.

What Comes Next

If your NYC rental building is pre-1960 and you haven’t completed Local Law 31 XRF lead testing, the right step is to schedule inspection now.
