Southaven, MS Building Safety: Fire Sprinkler Requirements (2026)

Chapter 4 of Title V governs sprinklers in the City of Southaven. Section 5-76(a) requires an approved automatic fire protection sprinkler system, designed and installed to NFPA standards, in new constructed buildings, major renovated buildings, and existing structures that change occupancy classification or must comply with the city's nonconforming ordinance.

The residential rules in subsection (a)(4) split three ways. Hotels and motels take NFPA 13. Lodging and rooming houses, board and care facilities, multifamily dwellings and townhouses comply with Section 903.3.1.2 of the International Fire Code as adopted, with sprinklers under NFPA Standards 13D and 13R up to four floors, and otherwise comply with Section 903.3.1.1. One and two-family dwellings of 6,500 square feet or more gross area under roof comply with NFPA 13D, while those under 6,500 square feet and not used as a child day care are exempt and follow the International Residential Building Code as adopted.

Other occupancies carry their own triggers. Educational buildings are covered in every case, including residential occupancies used as day care for children. Institutional buildings are covered in every case, including day care for children or adults with more than five patients or clients. Assembly, mercantile, business, industrial, storage and mixed occupancies are covered at 8,000 square feet or more gross area under roof, and H-1 through H-4 hazardous occupancies are sprinklered regardless of size.

Subsection (c) defines major renovation as construction costing more than fifty percent of the estimated cost of reconstructing the entire structure, or work the building official and the appropriate fire official consider major. Under subsection (d), an addition that pushes gross area under roof above the listed square footage brings the entire building under that requirement. Subsection (e) applies the most stringent standard where requirements conflict.

Supervision is mandatory. Under subsection (g), the system is electrically monitored by an approved central station meeting NFPA 71, and a runner or technician must arrive at the protected premises within 1 hour after a signal. Subsection (m) requires a licensed contractor to install piping within the building and to a point five feet outside it.
