Marietta, GA Fire Regulations: Smoke Detectors (2026)

Marietta's smoke-detector rule for multifamily buildings sits inside the same fire-protection section as the automatic sprinkler mandate, § 2-6-140(E), rather than in a stand-alone chapter. It requires early fire detection systems throughout all sections of multifamily occupancies as a baseline. For existing multifamily buildings that predate this fire-protection scheme, the code allows a lower-cost fallback: an approved battery-operated smoke detector satisfies the requirement in place of a hard-wired early detection system. That fallback is conditional: the bureau of fire prevention, established under § 2-6-030 within the fire marshal's office, may require the building's owner to upgrade to a hard-wire detection system if the battery-operated units are not being maintained according to the manufacturer's recommendations, meaning routine battery replacement and testing keeps a landlord on the cheaper option.

The bureau of fire prevention is the same office that enforces the whole fire prevention code citywide and whose deputies issue citations returnable to Marietta Municipal Court, so a failure tied to unmaintained detectors is enforced the same way as any other fire code violation. The general penalty clause, § 2-6-080, applies: prosecution follows a citation from a city fire or police officer, conviction carries a fine or imprisonment under § 11-4-080, the owner gets 30 days to correct the deficiency, and each day beyond that is a separate offense.
