NJ A494

New Jersey residential buildings with more than two dwelling units using light frame construction must install NFPA 13 automatic sprinkler systems, have fire partitions and horizontal separations with minimum two-hour fire-resistance ratings, and limit building height to 3-4 stories (60-85 feet) depending on whether framing is protected.

Developers must hire qualified fire watch wardens (active/retired firefighters, police officers, fire inspectors, or registered security officers) to monitor light frame construction sites during non-working hours from framing through final sprinkler inspection, or install comparable monitoring technology.

Fire watch wardens must submit weekly activity reports to the Division of Fire Safety, which may request revocation of construction permits for projects posing fire safety risks.

Identifying emblems marked "LF" must be affixed to exterior entrances of structures with light frame construction, and placards describing the primary structural system must be placed near fire alarm control panels and within 10 feet of main entrances.

Contractors working on covered residential projects must certify compliance with labor laws and be registered under The Public Works Contractor Registration Act, with the Commissioner of Community Affairs required to report on implementation effectiveness within one year.
