Hackensack, NJ Building Safety: Carbon Monoxide Detectors (2026)

Section 100-43E requires carbon monoxide detectors in all residential occupancies, exempting only buildings that have neither a fuel-burning device nor an attached garage, the two most common CO sources in a home. Where required, single-station carbon monoxide alarms must be installed and maintained in the immediate vicinity of sleeping areas, mirroring the sleeping-area emphasis of the chapter's smoke-alarm rule in the same section. The code gives owners flexibility on power source: alarms may be battery operated, hardwired, or plug-in type, provided the unit is listed and labeled in accordance with UL-2034, the Underwriters Laboratories standard for single- and multiple-station carbon monoxide alarms.

This CO requirement sits directly beside the smoke-alarm and fire-protection-system rules in Section 100-43, all part of Article VII, Firesafety Requirements, which opens by making the property owner responsible for providing and maintaining the required firesafety facilities and equipment and bars occupancy of premises that don't comply. As with the rest of the article, the requirement applies regardless of whether the unit is owner-occupied or rented.
