The law protects tenants—especially children—from lead exposure in older housing. Deteriorating lead paint creates hazardous dust and chips. Periodic inspections help landlords identify and correct problems before they cause harm.

Yes for most single-family, two-family, and multi-unit rental dwellings built before 1978. Properties built in 1978 or later are generally exempt, as are units that already hold a valid lead-free certification and certain short-term seasonal rentals.

A lead-safe certificate means no current lead hazards were found during the inspection (the unit is safe for occupancy at that time). A lead-free certificate is a higher standard that confirms no lead-based paint exists on the property at all. Lead-free status provides a long-term exemption from the ongoing lead-safe inspection requirements.

Once a dwelling unit receives a valid lead-free certification under New Jersey rules (N.J.A.C. 5:17), it is typically exempt from the periodic lead-safe inspections required by the 2021 rental law. This can eliminate the need for repeated inspections every three years or on tenant turnover.

XRF (X-ray fluorescence) is a non-destructive testing method that uses a handheld analyzer to measure lead content in paint without damaging surfaces. It is the primary tool used in full lead-based paint inspections. These inspections are often required to obtain a lead-free certification and can also support risk assessments or detailed documentation.

You would typically need a comprehensive XRF inspection if you want to pursue a lead-free certificate, plan major renovations, need detailed mapping of where lead paint exists, or require documentation beyond the standard rental lead-safe visual/dust assessment.

Every three years or upon tenant turnover—whichever comes first—unless the unit already has a valid lead-safe certificate or qualifies for an exemption (such as lead-free status).

Two years from the date of issuance. After it expires, the unit generally needs another inspection to remain compliant.

A licensed lead evaluation professional performs a visual assessment for deteriorating paint and other potential hazards. Dust-wipe sampling is commonly included when appropriate. The focus is on whether current hazards exist that would prevent a lead-safe determination.

You must remediate them using approved methods (abatement or interim controls). After the work is completed, a re-inspection is required. Only when the unit passes can a lead-safe certificate be issued.

Yes. Many landlords choose this route for long-term simplicity. Achieving lead-free status usually requires a full lead-based paint inspection (commonly performed with XRF) that demonstrates no lead-based paint is present above regulatory thresholds, followed by the proper certification process.

You must report tenant turnovers to the municipality, provide the lead-safe (or lead-free) certificate to new tenants, and supply required documents—including any certifications—to prospective buyers during a sale.

The lead-safe inspection can be visual, dust-wipe based, or a combination, depending on conditions and local/municipal requirements. A full XRF inspection for lead-free certification is more comprehensive and tests painted surfaces throughout the unit.

Proper certification reduces the risk of tenant health claims, helps with insurance and financing, supports smoother tenant turnovers, and—if you obtain lead-free status—can free you from the ongoing cycle of periodic inspections.

We are licensed New Jersey lead evaluation professionals. We perform the required lead-safe inspections and issue the proper certificates. We also conduct comprehensive XRF-based lead inspections that can support lead-free certification efforts. We explain the findings clearly, outline practical next steps, and help you choose the approach (ongoing lead-safe compliance or long-term lead-free exemption) that best fits your property and goals.
