Requires landlords of certain properties providing child care services who refuse lead service line replacements to install and maintain water filters.

This bill requires landlords of properties used for child care services (such as daycares, after-school programs, or preschools caring for six or more children under 13) to install and maintain NSF/ANSI-certified water filters at all drinking, food prep, and baby formula fixtures if they refuse access to replace lead service lines. Landlords must annually certify filter installation to the Department of Environmental Protection and face $500 daily penalties for noncompliance. Tenants can notify landlords of violations, triggering a 30-day correction period, after which they may seek court-ordered rent escrow to fund required filter installation. The requirement applies only if lead service lines remain connected and active.
