Requires certain residential buildings to have fire barriers in common attic areas.

This bill (A5028) requires fire barriers with a 3-hour fire-resistance rating in common attic areas of certain multi-unit residential buildings. It directly affects buildings with three or more stories and two or more dwelling units (defined as "qualified residential buildings"). The law mandates these barriers be installed within 180 days of new regulations taking effect, and new construction must comply before permits are approved. This amendment to New Jersey's fire safety codes aims to slow fire spread in attics, improving evacuation time and reducing fire damage risks.
