Clayton County, GA Building Safety: Fire Sprinkler Requirements (2026)

3, "Where installed," is the operative rule inside Clayton County's Automatic Sprinkler Systems article (Sec. ). All new construction must be protected throughout with an approved automatic fire protection system, but the code carves out buildings of 10,000 square feet or less that aren't classified High-hazard Group H, and lets hotels and motels up to four stories use an NFPA 13R system modified to cover all attics instead of a full NFPA 13 system. A third exception routes smaller new buildings that are educational, daycare, or residential board-and-care occupancies to NFPA 101 and the state's Minimum Fire Safety Standards instead.

Separately, subsection (b) requires every new multi-family residential structure, defined as three or more dwelling units with independent cooking and bathroom facilities, to be sprinklered regardless of size, though buildings up to four stories may again use NFPA 13R modified to also cover attics, breezeways and exterior balconies. Any sprinkler system required by the article must be tied into an approved alarm, detection and communication system under NFPA 72. The chief of the county fire and emergency services department sets installation rules based on National Fire Protection Association standards, and owners may appeal an installation order within ten days to the board of commissioners, with a further 20-day appeal window to superior court.

Once installed, equipment must be inspected at least annually by a state-certified sprinkler contractor, and the occupant must promptly notify the fire marshal if protection is withdrawn, interrupted or altered.
