Requires defibrillators in certain multiple dwellings; establishes Affordable Housing Defibrillator Fund.

This bill requires apartment buildings with 30 or more units in New Jersey cities with 50,000+ residents to install and maintain accessible automated external defibrillators (AEDs) in unlocked, clearly marked locations. Landlords must provide tenants with the AED location and ensure regular maintenance, while residents using AEDs gain legal immunity. It also creates an Affordable Housing Defibrillator Fund within the Department of Community Affairs to provide grants specifically to owners of affordable housing developments to cover compliance costs. The law takes effect seven months after enactment, aiming to increase access to life-saving AEDs in multi-unit buildings where cardiac emergencies may occur.
