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

"Sebastien's Law" requires landlords and homeowners' associations in New Jersey to install and maintain child-protection window guards in dwelling units or common areas where children under 10 reside or regularly stay. It applies to most multi-unit buildings (excluding seasonal rentals and certain first-floor/fire-escape windows) and mandates annual safety orientations for tenants. Landlords must provide written notice to homeowners' associations about tenant requests for common-area guards, and tenants may waive the requirement but can later rescind the waiver without lease consequences. The law also requires semi-annual inspections of installed guards to ensure safety compliance.
