Lead-safe vs. lead-free: which certificate should you get?
August 6, 2026Lead-safe: a visual pass, valid 2 years, the standard route. Lead-free: every painted surface tested with an XRF analyzer under N.J.A.C. 5:17-3.16(b); if the unit passes, it is permanently exempt from the law. Lead-free costs more upfront and many older units cannot pass it.
Side by side
| Lead-safe | Lead-free | |
|---|---|---|
| Method | Visual assessment of paint condition | XRF instrument reading on every painted surface |
| Validity | 2 years | Permanent; the unit exits the law |
| Cost | $250–350 typical single unit | Higher: per-surface instrument survey |
| Can an old unit pass? | Yes, if paint is intact | Only if old lead paint was actually removed or never present |
| Best for | Typical pre-1978 rentals with maintained paint | Gut renovations, post-1978 confirmations, long-hold portfolios |
The break-even logic
Lead-safe repeats: every 2–3 years, forever, per unit. Lead-free is once. If you gut-renovated a unit down to the studs, the XRF survey will likely pass, and one test ends the inspection cycle permanently. On a 10-year hold, that is 3–5 avoided visual inspections per unit. If the unit still has original trim and windows under layers of old paint, it will almost certainly not pass XRF, and lead-safe is the only realistic route.
Certificate questions
A DCA-licensed lead evaluation contractor with certified inspector/risk assessor staff. Same licensing world as the visual inspection, different service.
You now have documentation of where lead paint is, which is useful for planning. The unit simply continues on the lead-safe track.
Yes. The exemption attaches to the unit, which is a real selling point for renovated multifamily.
