Summary
Raleigh's housing code requires carbon monoxide alarms outside every sleeping area whenever an existing dwelling gets interior alterations, repairs, a fuel-fired appliance swap, or an addition that needs a permit, under UDO Sec. 11.6.3, which applies the North Carolina Residential Code Section 313 standard citywide.
Sec. 11.6.3. Minimum Standards for Basic Equipment and Facilities
Smoke and Carbon Monoxide Detectors
Every owner of an existing residential dwelling shall comply with North Carolina Residential Code Section 313. In existing dwellings, where interior alterations, repairs, fuel-fired appliance replacements, or additions requiring a permit occurs, or where one or more sleeping rooms are added or created, carbon monoxide alarms shall be installed outside of each separate sleeping area in the immediate vicinity of the bedrooms as directed by the alarm manufacturer.
Full Breakdown
Sec. 3, the Housing Code's Minimum Standards for Basic Equipment and Facilities, carries a dedicated 'Smoke and Carbon Monoxide Detectors' provision. Beyond the rental-specific smoke-detector duty owners already carry under state law, it separately requires every owner of an existing residential dwelling to comply with North Carolina Residential Code Section 313. That trigger is broader than rental status: whenever a dwelling gets interior alterations, repairs, a fuel-fired appliance replacement, or an addition that itself requires a permit, or whenever one or more sleeping rooms are added or created, the owner must install carbon monoxide alarms outside each separate sleeping area, positioned in the immediate vicinity of the bedrooms as the alarm manufacturer directs.
The same section requires any smoke detector installed under Sec. 5-2041 of the Raleigh City Code to be kept in good working order at all times, with batteries replaced at least once a year if it's battery-powered. 6: an inspector who finds a violation of the Sec. 3 minimum standards during a hearing triggers an administrative fee, and repeat violations of housing code standards within the same 12-month period carry a steeper fee the second time.
Violations & Fines
An inspection hearing that finds a violation of the minimum housing standards in Sec. 11.6.3, including a missing carbon monoxide alarm, triggers a $325 administrative fee under Sec. 11.6.17, rising to $650 if a further inspection within the same 12-month period turns up additional violations. Sec. 11.6.16 separately makes any violation of the housing code chapter a misdemeanor punishable as provided by law, on top of the civil penalties that apply to unfit-dwelling orders.
