Johns Creek, GA Fire Regulations: Smoke Detectors (2026)

Johns Creek does not set its own numeric smoke-alarm standard; it enforces the Georgia State Minimum Standard Codes (based on the International Residential, Building, and Fire Codes) adopted under O.C.G.A. § 8-2-20 and applied through the city's building-permit process and Chapter 21 fire-code enforcement. Under those codes, new and substantially renovated dwellings require interconnected smoke alarms in each sleeping room, outside each sleeping area, and on every level. The Johns Creek Fire Department's public guidance recommends installing at least one smoke detector on every level of the home including the attic and basement, no fewer than two detectors per home, and one in every bedroom. Battery-operated detectors should be tested once a month by holding the test button until it beeps, and batteries replaced at least once a year (ideally twice, when clocks change) or immediately on a low-battery chirp. The department offers free home visits to check detectors and look for fire hazards. Detectors should be replaced about every ten years per manufacturer guidance.
