"Sebastien's Law"; revises certain requirements for window guards in certain multiple dwellings.

"Sebastien's Law" changes New Jersey's window guard requirements from an opt-in system (where tenants must request window guards) to an opt-out system (where landlords must install window guards in units where children 10 or younger reside or are regularly present, unless tenants specifically waive this requirement). Landlords must provide tenants with annual notices about window guard requirements and maintain the guards with regular inspections. Tenants with children can waive the requirement in writing but may rescind this waiver at any time without penalty or lease violation. The law applies to multiple dwellings (apartment buildings with three or more units) and aims to increase child safety by ensuring window guards are installed where children are present.
