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

City Code § 97-17D, part of the Fire and Smoke and Carbon Monoxide Detector Devices article adopted in 1967 and amended in its entirety January 6, 2005 by Ordinance No. 05-8, requires carbon monoxide alarms in all dwelling units in buildings in Use Groups I-1, R-1, R-2, R-3 and R-4, except units in buildings with no fuel-burning device and no attached garage. Single-station alarms must be installed and maintained in the immediate vicinity of the sleeping area(s), and may be battery-operated, hard-wired, or plug-in type, but must be listed and labeled to UL-2034 and installed per NFPA-720.

Section 97-16 defines a carbon monoxide detector as an assembly incorporating a sensor, control components, and an alarm notification appliance in one unit that detects carbon-monoxide gas. Like smoke detectors, § 97-19 makes it unlawful for any tenant, occupant, owner or agent to tamper with, damage, destroy, steal, paint over, or otherwise disable a carbon monoxide detector or its parts. C. 2 ($35 to $125 depending on how far ahead the application is filed, plus a $15 reinspection fee) applies to that certificate.
