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

This bill requires new residential buildings with more than two dwelling units using light frame construction (like wood framing) to meet strict fire safety standards. It mandates automatic sprinkler systems throughout the building, fire-resistant walls extending from foundation to attic (with a minimum two-hour rating), and fire-resistant floor assemblies between units. Builders must also implement a fire watch program during construction - either using trained personnel (qualified firefighters or officials) or equivalent technology - to monitor for emergencies after work hours until sprinkler inspections are complete. These rules directly affect developers, contractors, and builders constructing qualifying residential projects in New Jersey.
