Memphis, TN Fire Regulations: Smoke Detectors (2026)

Section 9-44-6(A) sets the coverage rule in detail: each separate sleeping area needs its own detector (a sleeping area may be a single bedroom or two-plus adjoining bedrooms), and additional detectors are required at the head of every stairway to an occupied area and at the head of every interior basement stairway; where one detector can serve the sleeping area from just outside the bedrooms, that single placement is acceptable. The alarm must be clearly audible in every bedroom over background noise with intervening doors closed, and the installer must test audibility with household equipment such as window air conditioners and humidifiers running, then either witness the owner's sign-off or send written notice that the units were installed and tested per the manufacturer's specifications.

Detectors in sloped-ceiling rooms must sit on the high side, and one at a stairway head must be positioned so an intervening door or obstruction can't block smoke from reaching it. Subsection (B) exempts a unit that already has an approved alternate electronic fire-detection system, once the fire official signs off on it. Subsection (C) puts installation and maintenance duty on the owner, lessor or managing agent, while occupants must run their own operational safety tests at least monthly and notify the owner in writing of any malfunction; the owner/agent must also test common-corridor and stairway-head units at least monthly and re-test every detector whenever a unit turns over to a new occupant. Batteries must be replaced per the alarm manufacturer's recommendations.
