Summary

North Carolina requires working smoke alarms in every home. Landlords must provide operable, UL-listed alarms at the start of each tenancy under NCGS 42-42, and any new or replacement alarm must be a tamper-resistant 10-year lithium unit. New construction follows NC Residential Code R314.

City-specific rules exist: Durham has its own smoke detectors rules that differ from Durham County's county-level regulations. If you live in Durham, check the city-specific page instead.

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.

Full Breakdown

Under G.S. 42-42(a)(5) a landlord must provide operable smoke alarms that are UL-listed, install them to NFPA or manufacturer standards, place fresh batteries at the start of tenancy, and repair or replace within 15 days of written notice. Since January 1, 2013, any newly installed or replaced alarm must be a 'tamper-resistant, 10-year lithium battery smoke alarm' unless it is hardwired. The NC Residential Code requires alarms in each bedroom, outside sleeping areas, and on every level of new or renovated homes; carbon-monoxide alarms are also required in rentals with fuel appliances or an attached garage under G.S. 42-42(a)(7).

Violations & Fines

A landlord who fails to install, replace, or repair a required smoke alarm commits an infraction subject to a fine of up to $250 per violation.

Frequently Asked Questions

Who buys smoke-alarm batteries in a rental?
The landlord installs fresh batteries at move-in; the tenant replaces them as needed during the tenancy, unless it is a sealed 10-year lithium alarm.
Are carbon-monoxide alarms required?
Yes. In rentals with fossil-fuel appliances, fireplaces, or an attached garage, the landlord must provide a CO alarm under G.S. 42-42(a)(7).
