Requires landlords to disclose existence of lead service lines and lead water supply plumbing to tenants.

S 2165 requires New Jersey landlords to inspect rental properties within 90 days of the law taking effect to identify lead service lines or lead plumbing. If lead pipes are found, landlords must disclose this to current tenants and provide written notice about health risks to prospective tenants before new leases. Violations carry a $500 civil penalty per offense, with each day of noncompliance considered a separate violation. The bill directly affects landlords and tenants in rental properties served by lead plumbing, aiming to increase transparency about potential health hazards in drinking water.
