NJ S1285

Mandates installation of fuel gas sensor devices in dwelling units in buildings with fewer than three units upon change of occupancy, sale, lease, or when a certificate of occupancy is required.

Extends fuel gas sensor requirements to hotels, multiple dwellings, and rooming and boarding houses, with inspections conducted by municipal fire officials upon occupancy changes.

Fuel gas sensor devices must comply with Underwriters Laboratories Standard 2075 or Standard 1484 and meet National Fire Protection Association (NFPA) 715 installation requirements.

Allows combination devices that detect both carbon monoxide and fuel gas to satisfy both requirements simultaneously.

Takes effect 180 days after enactment, with fuel gas sensor installation permitted to be deferred until the second inspection if existing smoke detectors and carbon monoxide sensors pass initial inspection.
