Chapel Hill, NC Fire Regulations: Smoke Detectors (2026)

Section 9-69 of the Housing Code targets rental units that were lawfully built before smoke detectors were required. The owner of such a unit must install, or make sure a smoke detector is installed, in the corridor or other space leading to every bedroom, with installation complete and the detectors fully operable within 90 days of the section's effective date. The detector itself must meet standards under § 9-69(b): it must be battery operated or wired to the building's electrical current, installed according to the manufacturer's instructions, capable of an audible alarm when activated, and equipped with either a visible light showing it is working or an audible trouble signal that sounds at least once a minute for seven straight days when it needs attention.

Under § 9-69(c), the owner's duty does not end at installation: the owner must maintain or ensure the detector stays in good working order, and if it runs on batteries, those batteries must be replaced at least once a year. The requirement sits within Article IV of the Housing Code, the same article that sets minimum plumbing, heating, and electrical standards for every dwelling and dwelling unit in town, and its enforcement runs through the same building inspector who administers the rest of Chapter 9.
