New Jersey Lead-in-Water Disclosure Law 2026: Pre-1986 Buildings

The disclosure requirement is triggered by construction date and service line composition, specifically properties built before 1986 or served by a lead service line or a line of unknown composition.

[Cite: Assembly Bill 2929, P.L.2025, c.144]

That framing means a landlord doesn't get to wait for an actual lead test failure before disclosure applies; the age and service-line status of the building itself is what triggers the obligation.

The required disclosure includes an acknowledgment of whether the property is served by a lead service line or a line of unknown composition, a note that housing built before 1986 may be serviced by a lead service line, copies of any formal lead action level exceedance notices from the prior 3 years unless corrected 12 or more months earlier, and any code violation citations issued within the 12 months before lease signing.

That's a specific, multi-part document, not a single checkbox; a landlord assembling it needs the building's service-line records and any recent violation history on hand, not just a generic disclosure template.

The 90-day compliance clock doesn't start on the law's signing date; it starts after the Department of Health publishes its educational notice and the Department of Community Affairs separately releases the model disclosure form.

[Cite: Assembly Bill 2929, P.L.2025, c.144]

A landlord working off a single assumed start date, like the commonly cited November 15, 2026 figure, should confirm that both of those publications have actually happened before treating that date as a hard deadline, since it depends on 2 separate agencies acting.

The specific November 15, 2026 compliance date circulating in secondary legal summaries of this law is derived from an assumed publication timeline, not from a confirmed Department of Health or Department of Community Affairs notice.

A property manager building a compliance calendar around that date should verify it against an actual DOH or DCA publication closer to the date, rather than treating a secondary estimate as the confirmed trigger.

The disclosure has to be delivered either as a separate written notice using the state's model form, or as a rider to the written lease that the tenant separately signs, printed in at least 12-point type; for an oral lease, a standalone notice is required.

[Cite: N.J.S.A. 58:12A-12.3b, as created by P.L.2025, c.144]

A landlord who simply adds a sentence about lead service lines into the body of a standard lease, without a separately signed rider or the required type size, likely hasn't satisfied this delivery requirement.

If the water system serving the property had a formal lead action level exceedance notice in the past 3 years, that notice has to be included in the disclosure, unless the issue was corrected 12 or more months before the lease is signed.

[Cite: N.J.S.A. 58:12A-12.3a, as created by P.L.2025, c.144]

A landlord relying on an old, uncorrected exceedance notice without including it in the disclosure is withholding information the statute specifically requires, even if the landlord believes the issue has since resolved informally.

Water systems serving these properties have to provide free annual lead testing upon a customer's request, and if a lead action level exceedance is found, testing steps up to every 60 days until 2 consecutive results come back within the standard.

[Cite: N.J.S.A. 58:12A-12.9a, as created by P.L.2025, c.144]

That testing obligation sits with the water system, not the landlord directly, but a landlord assembling a disclosure needs to know whether that testing has actually turned up an exceedance to include in the required notice.

A landlord may not obstruct a water system's efforts to replace a lead service line at the property.

[Cite: N.J.S.A. 58:12A-12.9b, as created by P.L.2025, c.144]

If a landlord denies the access a water system needs to carry out that replacement, the tenant gets a specific remedy: the right to terminate the lease without penalty.

A tenant's ability to walk away from a lease without penalty over denied replacement access gives landlords a direct financial reason to cooperate with scheduled lead service line work rather than delay it.

[Cite: N.J.S.A. 58:12A-12.9b, as created by P.L.2025, c.144]

A landlord juggling renovation timing or tenant access logistics should treat a scheduled lead line replacement as a priority appointment, not a flexible one, given what's at stake if access gets denied.

Reported penalties for landlord noncompliance escalate by violation: $100 for a first violation, $500 for a second, and $1,000 for a third or subsequent violation, enforced by the Department of Community Affairs; water system violations are separately enforced by the Department of Environmental Protection.

[Cite: Insurance Journal, "New Jersey Requires Testing and Disclosure of Lead in Water Systems"]

That split enforcement structure means a landlord's own disclosure failure and a water system's testing failure are treated as 2 distinct compliance tracks, each with its own enforcing agency.

The practical starting point is identifying every property in the portfolio built before 1986, or with an unknown or confirmed lead service line, since those are the properties this disclosure requirement actually covers.

For each of those properties, pulling together the service-line status, any lead action level exceedance history from the past 3 years, and any code violations from the past 12 months well before the compliance date gives a landlord the actual source material the disclosure requires, rather than scrambling to assemble it once the Department of Health and Department of Community Affairs publications confirm the real start date.
