In North Carolina, as of
January 1, 2010 the landlord must provide a minimum of one operable carbon monoxide detector per rental unit per level, either battery operated or electrical, that is listed by a nationally recognized testing laboratory that is OSHA approved to test and certify to American National Standards
Institute/Underwriters Laboratories Standards ANSI/UL2034 or ANSI/UL2075.
The installation of the carbon monoxide detectors must be in accordance with either
the standards of the National Fire Protection Association or the minimum protection
designated in the manufacturer's instructions, which the landlord shall retain or
provide as proof of compliance.
A landlord that installs one carbon monoxide detector per rental unit per level shall
be deemed to be in compliance with standards under this subdivision covering the
location and number of detectors.
The landlord shall replace or repair the carbon monoxide detectors within 15 days of
receipt of notification if the landlord is notified of needed replacement or repairs in
writing by the tenant.
The landlord shall ensure that a carbon monoxide detector is operable and in good
repair at the beginning of each tenancy. Unless the landlord and the tenant have a
written agreement to the contrary, the landlord shall place new batteries in a
battery operated carbon monoxide detector at the beginning of a tenancy with a North Carolina lease, and the
tenant shall replace the batteries as needed during the tenancy. Failure of the
tenant to replace the batteries as needed shall not be considered as negligence on
the part of the tenant or the landlord.
A carbon monoxide detector may be combined with smoke detectors if the
combined detector does both of the following:
(i) complies withANSI/UL2034 or ANSI/UL2075 for carbon monoxide alarms and
ANSI/UL217 for smoke detectors; and
(ii) emits an alarm in a manner that clearly differentiates between detecting the
presence of carbon monoxide and the presence of smoke.
This subdivision applies only to dwelling units having a fossil fuel burning heater or
appliance, fireplace, or an attached garage. Any operable carbon monoxide detector
installed before January 1, 2010, shall be deemed to be in compliance with this
subdivision.
