Establishes fire safety standards and protocols for certain light frame residential construction; requires placards identifying primary structural systems of buildings.

This bill (A5031) establishes fire safety requirements for new residential buildings in New Jersey using light frame construction (wood or combustible materials) that contain more than two dwelling or sleeping units, such as hotels, multiple dwellings, or rooming houses. It mandates automatic sprinkler systems meeting NFPA 13 standards, 2-hour fire-resistant barriers extending from foundation to attic, and height/story limits (3 stories/60ft or 4 stories/85ft depending on framing protection). The bill also requires developers to hire certified fire watch wardens (or use equivalent monitoring technology) during non-working hours for all light frame construction projects until final sprinkler inspection, and mandates visible placards identifying structural systems near fire alarms and exterior entrances. These provisions directly affect builders, developers, and property owners constructing qualifying residential buildings.
