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

This bill (A 483) requires landlords of multiple dwellings with 30+ units in urban municipalities (population 50,000+) to install and maintain accessible automated external defibrillators (AEDs) in unlocked locations with clear signage. It directly affects landlords in qualifying urban apartment buildings, with the Affordable Housing Defibrillator Fund providing grants to owners of affordable housing developments to cover AED costs. Key provisions include mandatory AED testing/maintenance, tenant notification of locations, and legal protection for users from civil liability. The bill would take effect 7 months after enactment, increasing emergency medical access in high-density residential areas.
