Summary
Greenville dwellings with a fossil-fuel heater, appliance, fireplace, or attached garage must have at least one operable carbon monoxide detector per level, listed by a nationally recognized testing laboratory such as UL.
(B) Carbon monoxide detectors. Dwellings shall have a minimum of one operable carbon monoxide detector per level, either battery-operated or electrical, that is listed by a nationally recognized testing laboratory (such as Underwriters Laboratories). This section applies only to dwellings having a fossil-fuel burning heater, appliance, or fireplace, and in any building or structure having an attached garage. Any operable carbon monoxide detector installed before January 1, 2010, shall be deemed to be in compliance with this section.
Full Breakdown
Section 9-1-97(B) of the Greenville City Code targets the specific fire-risk conditions that produce carbon monoxide: any dwelling with a fossil-fuel burning heater, appliance, or fireplace, and separately, any building or structure with an attached garage where vehicle exhaust can migrate indoors. Those dwellings must maintain a minimum of one operable carbon monoxide detector per level, battery-operated or electrical, carrying a listing from a nationally recognized testing laboratory such as Underwriters Laboratories. The section grandfathers existing installations: any operable carbon monoxide detector installed before January 1, 2010 is deemed compliant even if it does not meet current listing language, so long as it still works.
This sits directly beneath the smoke detector standard in subsection (A) within the same Minimum Housing Code chapter, and the two are cross-referenced: a combination smoke/CO unit that satisfies subsection (B) can substitute for a stand-alone hardwired smoke alarm. Enforcement runs through the same Code Enforcement Supervisor process as the rest of the Minimum Housing Code: a missing or inoperable CO detector found during an inspection is treated as a deficiency that can be folded into a written repair order, with the owner given a set window to correct it before the case moves toward the hearing procedure in Sec. 9-1-111.
Violations & Fines
A dwelling required to have carbon monoxide detection that lacks one, or has a nonfunctional unit, is cited as a Minimum Housing Code deficiency under Sec. 9-1-97(B). The Code Enforcement Supervisor documents the defect and can issue a repair order; unresolved violations proceed to the administrative hearing and enforcement track under Sec. 9-1-111.
