Summary

Cornelius follows the NC State Residential Code requiring working smoke alarms in every sleeping room, outside sleeping areas, and on each level of a dwelling. Rental properties must have alarms maintained by landlords.

§ 42-42. Landlord to provide fit premises.

(a) The landlord shall:

(5) Provide operable smoke alarms, either battery-operated or electrical, having an Underwriters' Laboratories, Inc., listing or other equivalent national testing laboratory approval, and install the smoke alarms 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. The landlord shall replace or repair the smoke alarms 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 smoke alarm 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 smoke alarm at the beginning of a tenancy and the tenant shall replace the batteries as needed during the tenancy, except where the smoke alarm is a tamper-resistant, 10-year lithium battery smoke alarm as required by subdivision (5a) of this subsection. 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. (5a) After December 31, 2012, when installing a new smoke alarm or replacing an existing smoke alarm, install a tamper-resistant, 10-year lithium battery smoke alarm. However, the landlord shall not be required to install a tamper-resistant, 10-year lithium battery smoke alarm as required by this subdivision in either of the following circumstances:

a. The dwelling unit is equipped with a hardwired smoke alarm with a battery backup.

b. The dwelling unit is equipped with a smoke alarm combined with a carbon monoxide alarm that meets the requirements provided in subdivision (7) of this section.

Cornelius-Lemley Fire Rescue offers free smoke alarm installation to qualifying residents.
