Chatham County, GA Fire Regulations: Smoke Detectors (2026)

Section 21-515(1)(h) of the Code of Chatham County, part of the Property Maintenance article amended March 25, 2011, sets the smoke-alarm floor for every dwelling unit in unincorporated Chatham County. The detector must be an approved, listed model installed per the manufacturer's instructions and must sound an audible alarm when triggered. The code names the testing standard directly: UL217 (1989), Single and Multiple Station Smoke Detectors. Placement isn't left to the owner's judgment. The section requires one detector on the ceiling or wall outside each separate sleeping area, one inside each room used for sleeping, and one on every story of the dwelling, including basements and cellars, but not crawl spaces or uninhabitable attics.

Split-level units get a narrow break: if there's no door between the levels and the lower floor sits less than a full story below the upper one, a single alarm on the upper level covers both. Enforcement runs through the Director of Inspections, the code official, under Section 21-509, which sets the penalty for any violation of the article at up to $500, up to 30 days in the county jail, or up to 60 days on the work gang, and treats each day the violation continues as a separate offense.

A dwelling missing required detectors can also be swept into the condemnation track under Sections 21-513 and 21-514 if the code official finds the unit unfit for habitation.
