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

This bill requires owners of qualifying multi-unit residential buildings (three or more stories with two or more dwelling units) to install three-hour fire barriers in common attic, loft, or cockloft areas. These barriers must slow fire spread between units, improving safety for residents and firefighters during emergencies. The requirement applies to both new construction (where permits must include the provision) and existing buildings, which must comply within 180 days of implementing regulations. The Commissioner of Community Affairs must establish specific rules within six months of the bill's effective date to enforce these fire safety standards.
