| IBC — International Building Code | 2024 IBC (2024 edition of the International Building Code, as published by the International Code Council, Incorporated) — NOT 2021. The row previously read "2021"; the edition was moved to 2024 by SL 2026, ch 59, ss 1-2, and the prior value was a stale reading of the pre-2026 statute. | SDCL 11-10-5 (New non-residential construction standards — Building code ordinance — Compliance with International Building Code — Modifications — Exclusions), most recently amended by SL 2026, ch 59, s 1; read together with SDCL 11-10-6 (New construction standards — No building code ordinance — International Building Code applied — Exclusions), most recently amended by SL 2026, ch 59, s 2.

| IECC — International Energy Conservation Code | 2009 IECC — VOLUNTARY ONLY, RESIDENTIAL ONLY. SOUTH DAKOTA HAS NO MANDATORY ENERGY CODE OF ANY EDITION, ANYWHERE, FOR ANY BUILDING TYPE. SDCL 11-10-7 in full, verbatim: "The State of South Dakota hereby adopts the International Energy Conservation Code of 2009, published by the International Code Council, as the voluntary standard applying to the construction of new residential buildings in the state." The operative word is "voluntary" and it is in the statute itself, not a gloss. Scope is limited twice over: (1) VOLUNTARY — no person is obliged to build to it; (2) NEW RESIDENTIAL BUILDINGS ONLY — the statute names no commercial, non-residential or state-owned building. NO SOUTH DAKOTA STATUTE MAKES ANY IECC EDITION MANDATORY FOR COMMERCIAL CONSTRUCTION: SDCL 11-10-5 and 11-10-6 govern non-residential buildings and adopt only the International Building Code, naming no energy code and no ASHRAE 90.1. The only enforceable consequence attached to the 2009 IECC anywhere in South Dakota law is a DISCLOSURE duty, not a construction duty — SDCL 11-10-8 requires a builder or seller of a previously unoccupied new single-family or up-to-four-unit residential building to disclose energy-efficiency information to the buyer (SDCL 11-10-9 allows a federal-law alternative; SDCL 11-10-10 prescribes the builder statement). A South Dakota house may lawfully be built to no energy standard at all provided the builder discloses that fact. | SDCL 11-10-7 (Energy conservation code adopted as voluntary standard for new residential buildings); source note SL 2009, ch 63, § 1; SL 2011, ch 72, § 5. Related enforceable duty: SDCL 11-10-8 to 11-10-10 (energy efficiency disclosure). · source ↗ |
| IFC — | 2015 IFC — the International Fire Code, 2015 edition, adopted by the SOUTH DAKOTA DEPARTMENT OF PUBLIC SAFETY (State Fire Marshal) at ARSD 61:15:01:01, effective 2016-10-17 (43 SDR 56). Adopting words verbatim, the whole rule: "The standards of fire safety set forth in the International Building Code, 2015 edition; International Fire Code, 2015 edition; and the International Mechanical Code, 2015 edition; and referenced standards, except as modified, amended, or deleted in this chapter, are the rules of the South Dakota Department of Public Safety authorized by SDCL 34-29B-2." NOT 2021 AND NOT 2024 — SOUTH DAKOTA'S FIRE CODE IS THREE I-CODE CYCLES BEHIND THE CURRENT EDITION AND HAS NOT MOVED SINCE 2016. NO APPENDICES ARE NAMED, so no IFC appendix is South Dakota law. THE ADOPTION IS PARTIAL: sections are deleted at 61:15:01:02 and referenced NFPA standards are pinned to different editions at 61:15:01:04, so the enforceable South Dakota text is NOT the model 2015 IFC as published. | ARSD 61:15:01:01 (Conformity with national standards); General Authority SDCL 34-29B-2; Law Implemented SDCL 34-29B-2, 34-29B-10; current version 43 SDR 56, effective October 17, 2016 · source ↗ |

ADOPTING WORDS VERBATIM, THE WHOLE RULE: "The standards of fire safety set forth in the International Building Code, 2015 edition; International Fire Code, 2015 edition; and the International Mechanical Code, 2015 edition; and referenced standards, except as modified, amended, or deleted in this chapter, are the rules of the South Dakota Department of Public Safety authorized by SDCL 34-29B-2."

NOTE THE FRAMING: the IMC is adopted as a STANDARD OF FIRE SAFETY and becomes "the rules of the South Dakota Department of Public Safety", not a building-permit mechanical code. The adoption is PARTIAL -- "except as modified, amended, or deleted in this chapter" routes to ARSD 61:15:01:02 et seq. · source ↗ |
| IPC — International Plumbing Code | NOT ADOPTED — SOUTH DAKOTA DOES NOT ADOPT THE INTERNATIONAL PLUMBING CODE, IN ANY EDITION, ANYWHERE. The phrase "International Plumbing Code" does not appear in the governing chapter. THE STATEWIDE PLUMBING CODE IS THE UNIFORM PLUMBING CODE (UPC), 2024 EDITION, PUBLISHED BY IAPMO — a different model family from the I-Codes and a different publisher. Adopting words verbatim, ARSD 20:54:02:01: "All plumbing materials and plumbing systems or parts of plumbing systems installed must meet or exceed the minimum provisions of the Uniform Plumbing Code, 2024 edition, including Appendices A, B, C, D, E, I, K, L, M, N, O, Q, and R, with the following exceptions". Publisher note verbatim: "Uniform Plumbing Code, 2024 edition, International Association of Plumbing and Mechanical Officials. Copies may be obtained from the International Association of Plumbing and Mechanical Officials, 5001 East Philadelphia Street, Ontario, CA 91761." Named adopted appendices are A, B, C, D, E, I, K, L, M, N, O, Q and R — appendix selection is enforceable law and "2024 UPC" alone understates it. | ARSD 20:54:02:01 (Conformance with uniform code -- Exceptions); General Authority and Law Implemented SDCL 36-25-15; current version 52 SDR 106, effective May 25, 2026 (prior 52 SDR 42, effective October 28, 2025) · source ↗ |
| IRC — International Residential Code | 2024 IRC (municipal local-option only; NO mandatory statewide residential code) | SDCL 11-10-12 (Residential structures--Enactment of International Residential Code standards--Modifications--Sprinkler system requirements). Source: SL 2022, ch 35, s 3; SL 2026, ch 59, s 4. ADOPTING WORDS VERBATIM, THE WHOLE SECTION: "The governing body of a municipality may enact requirements for construction, alteration, movement, enlargement, replacement, repair, equipment, use and occupancy, location, removal, and demolition of a residential structure by adopting the 2024 edition of the International Residential Code, as published by the International Code Council, Incorporated. The governing body may, at any time, amend any provision of the International Residential Code. The governing body may not require the installation of a sprinkler system in a residential structure or impose any requirements that are more stringent than the requirements in the 2024 edition of the International Residential Code. For purposes of this section, 'residential structure' means a detached one-family or two-family dwelling, and townhouses not more than three stories in height, with a separate means of egress and any accessory structure of the dwelling or townhouse." NOTE THE PERMISSIVE VERB: "may enact" / "may ... amend" / "may not require" -- there is no mandatory statewide residential code in South Dakota and this statute does not create one. · source ↗ |
| NEC — National Electrical Code (NFPA 70) | 2023 NEC (NFPA 70, 2023 edition) INCLUDING TENTATIVE INTERIM AMENDMENTS 23-1 THROUGH 23-15, AS MODIFIED BY SIX SOUTH DAKOTA EXCEPTIONS. The TIAs are named individually and are part of South Dakota law; the six exceptions are deletions/modifications, so the enforceable South Dakota text is NOT the model 2023 NEC as published. SCOPE: statewide, all electrical installations under the State Electrical Commission's jurisdiction (SDCL ch. 36-16) -- residential AND non-residential, which is why applies_to is left NULL (the column admits only 'residential' or 'commercial'). | ARSD 20:44:14:01(11) (State Electrical Commission -- General definitions), General Authority SDCL 36-16-12, Law Implemented SDCL 36-16-1; current version 51 SDR 54, effective November 12, 2024. ADOPTING WORDS VERBATIM: "'National Electrical Code,' the code published by the National Fire Protection Association (2023 edition, including tentative interim amendments 23-1 through 23-15) with the following exceptions:" followed by lettered exceptions (a)-(f). CORRECTION TO THE PRIOR ROW: this row previously cited SDCL 36-16-12 as the adopting instrument. IT IS NOT. SDCL 36-16-12 ("Seal of commission--Scope of rules") only empowers the State Electrical Commission to promulgate rules under ch. 1-26 and names no code and no edition; its text was read in full and contains no reference to the NEC. The adoption happens in the Commission's rule, not in the statute. The prior source_url pointed at SDCL 11-10-5, a NON-RESIDENTIAL BUILDING CODE statute unrelated to electrical work. · source ↗ |
