Summary
One- and two-family homes in Jackson carry no sprinkler mandate: Sec. 26-60(d) expressly deletes IRC Section R313 when adopting the 2018 Residential Code. New, renovated or modified commercial buildings are different: Sec. 58-37's 2024 International Fire Code amendments require automatic sprinklers once a building crosses occupancy-specific area or occupant-load thresholds, and self-service storage facilities must always have them.
(d)The International Residential Code, 2018 Edition (with amendments). Subject to the following: ... delete section R313; delete section P2904; delete chapter 11 ... 903.2: Where required. Approved automatic sprinkler systems in new buildings and structures shall be provided in the locations described in Sections 903.2.1 through 903.2.12.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 55).
Full Breakdown
Sec. 26-60(d) adopts the International Residential Code, 2018 Edition, for one- and two-family dwellings but lists specific local deletions, including "delete section R313," the IRC's residential fire-sprinkler-system section, along with P2904 and chapter 11. Commercial and larger buildings fall instead under the 2024 International Fire Code adopted at Sec. 58-36, as amended by Sec. 58-37. 12," which set numeric triggers by occupancy group: Group B offices need a system once a fire area tops 5,000 square feet; Group E schools trigger at a 5,000-square-foot fire area or a 300-person occupant load (with an exception for every classroom having a ground-level exterior exit); Group M retail and Group S-1 storage trigger at 5,000 square feet, more than three stories, or a combined 10,000 square feet across floors; and Group S-2 open parking garages trigger at 48,000 square feet.
5 specifically for self-service storage facilities, requiring an automatic sprinkler system in every new, renovated or modified facility of that type regardless of size, plus a mesh screen 18 inches below the sprinkler heads to keep stored goods clear. 3.
Violations & Fines
Sec. 58-37's amended Section 113.4 makes violating the fire code, including a missing required sprinkler system, a misdemeanor punishable by a fine of not more than $1,000.00 or imprisonment not exceeding 90 days, or both, with each day a violation continues after notice deemed a separate offense. The City Fire Marshal, designated the "fire code official" under Sec. 58-37(a), administers and enforces these sprinkler requirements.
