Summary

Every dwelling unit in New Orleans must have an operable carbon monoxide detector with a long-life sealed battery under City Code § 26-230(b), added by ordinance in October 2024. The code official can test the alarm during an inspection, and the same section separately requires an operable fire detection system in every unit.

All systems, devices, and equipment to detect the presence of carbon monoxide and actuate an alarm shall be maintained in an operable condition at all times in accordance with the Fire Code of the City of New Orleans, as amended. All dwelling units shall have an operable carbon monoxide detector with a long-life sealed battery. The code official or duly authorized representative may test the system and alarm to determine if it is functioning and operable.

Full Breakdown

Section 26-230 covers 'Fire and carbon monoxide protection systems' within the Minimum Property Maintenance Code's Division 7 (Mechanical and Electrical Requirements). Subsection (a) requires every dwelling unit to have 'an operable fire detection system and alarm,' which can be hard-wired or run on a ten-year sealed lithium battery. S. Ordinance No. 30078 on October 10, 2024, extends the same operability duty to carbon monoxide protection: every dwelling unit must have 'an operable carbon monoxide detector with a long-life sealed battery,' maintained in accordance with the city's Fire Code.

Both subsections give 'the code official or duly authorized representative' the power to test the system and alarm during an inspection to confirm it's actually functioning, a device installed but dead or removed does not satisfy the section. The requirement sits inside the broader Minimum Property Maintenance Code framework, so it applies to every dwelling unit citywide, owner-occupied or rented, and ties into the same enforcement and penalty structure as the rest of Chapter 26, Article IV: a code official's notice, a Chapter 6, Article II hearing if contested, and a § 26-232 penalty, capped at the § 26-37 maximum per violation, with daily continuation counted as a fresh offense.

Because § 26-230 was only added in its current CO-specific form in late 2024, older listings or inspection checklists that don't mention carbon monoxide detectors are working from an outdated version of the code.

Violations & Fines

A missing or non-functioning carbon monoxide detector is enforced the same way as any other Minimum Property Maintenance Code violation: a code official's notice, a Chapter 6, Article II hearing if contested, and a § 26-232 fine capped by § 26-37 per violation, with each day the condition continues after notice a separate offense.

Frequently Asked Questions

Does every rental in New Orleans need a carbon monoxide detector?
Yes. City Code § 26-230(b) requires every dwelling unit to have 'an operable carbon monoxide detector with a long-life sealed battery,' maintained in accordance with the Fire Code. This requirement was added to the code by ordinance in October 2024.
Can a code inspector actually test my smoke or CO alarm?
Yes, § 26-230 gives 'the code official or duly authorized representative' express authority to test the fire and carbon monoxide systems during an inspection to confirm they're functioning and operable, not just installed.
What kind of battery does the carbon monoxide detector need?
The code requires a 'long-life sealed battery,' the same standard it sets for the fire alarm system in § 26-230(a), which specifies a ten-year sealed lithium battery as one compliant option alongside hard-wired systems.
