Southaven, MS Fire Regulations: Smoke Detectors (2026)

Section 4-262 of the Southaven Code sets the scope. Detectors are required in every new and existing dwelling unit within an apartment complex, dormitory, townhouse or duplex condominium, and in every new and existing guest room in a motel and hotel, all in compliance with the International Building Code and the International Fire Code as adopted. The Board of Aldermen adopted the 2024 International Fire Code, excluding Appendices A and J, in Section 5-26, so that code supplies the technical detail behind this chapter.

Equipment must be an approved U.L. or F.M. listed detector installed under the manufacturer's recommendation. When it activates, the alarm must be clearly audible in all bedroom units and over background noise with all intervening doors closed. The installer runs the audibility test with household equipment in full operation, such as window air conditioners and room humidifiers, in the presence of the owner or the owner's authorized representative. If nobody can attend, the installer gives the owner a written notice that the detectors were installed to the manufacturer's specifications and tested.

Placement rules are specific. Detectors in rooms with a ceiling slope greater than one foot of rise per eight feet horizontally go on the high side of the room. A detector at the head of a stairway must sit where an intervening door or obstruction cannot keep rising smoke away from it. A unit with more than one story needs a detector on each story, including cellars and basements but not uninhabitable attics. In a split-level unit, only the upper level needs one if the lower level is less than one full story below, unless a door separates the levels.

Section 4-263 exempts a residential occupancy that operates an electronic or other fire detection system approved by the fire marshal or a deputy or assistant fire marshal as an alternate alarm system, for the areas that system protects. That system must meet the International Fire Code as adopted and NFPA 72.

Section 4-264 assigns responsibility. The owner provides and installs working detectors. In apartment complexes, hotels and motels, the owner or authorized agent inspects each detector annually and keeps records of the date, the inspector's name and any maintenance, available on request to the fire authority having jurisdiction. In townhomes, condominiums and duplexes, the occupant tests the detector and replaces batteries.
