EDITION CONFIRMED CORRECT THIS RUN AND THE "SIBLING-EDITION-LAG" HYPOTHESIS THAT SEEDED THIS TARGET IS **DISPROVED** FOR ARKANSAS. The Arkansas Department of Health's own published code states it is "based on the 2018 International Fuel Gas Code".

| IMC — International Mechanical Code | 2021 IMC — adopted verbatim, WITH NO ARKANSAS AMENDMENTS. Note the naming trap: the state's own current-codes sheet calls this line "2021 International Mechanical Code", NOT an "Arkansas Mechanical Code". There is no state-authored mechanical code text in force in Arkansas today; the phrase "Arkansas Mechanical Code" is a HISTORICAL name belonging to the Arkansas Department of Health's mechanical code (2003 ed., updated to a 2010 ed. proposed effective 2010-09-01), which no longer carries the mechanical code. Mechanical now sits with the HVACR Licensing Board. | Rules of the HVACR Licensing Board, Section XXIII (Administrative Rules Pertaining to the Licensing of Heating, Ventilation, Air Conditioning and Refrigeration Contractors, rules effective June 3, 2022), promulgated under Act 277 of 1991 as amended and Act 96 of 1913 as amended (codified at A.C.A. tit. 17 ch. 33). Codified in the Arkansas rules numbering as 235.13.22 Ark. Code R. s 006 ("Rules of the HVACR Licensing Board — International Mechanical Code Update") — that codified designation was seen only on unofficial reporters and is recorded as an aid, not as the verified instrument; the verified instrument is the promulgated rule text itself on the agency host. · source ↗ |
| IPC — International Plumbing Code | 2018 IPC — adopted as the ARKANSAS PLUMBING CODE, 2018 Edition (a state-authored amended edition of the 2018 International Plumbing Code, not the model text). The prior Arkansas Plumbing Code was based on the 2006 IPC (pub. Feb 2008, minor revisions 2008, 2012, 2013), so this adoption moved Arkansas twelve model-code years in one step. No 2021 or 2024 edition is adopted in Arkansas as of 2026-09: the official Code of Arkansas Rules part is still titled "2018 Arkansas Plumbing Code". | 17 CAR pt. 65 (Code of Arkansas Rules, Title 17 ch.

*** **NOT THE 2023 NEC, AND THIS IS THE POINT OF THE ROW.
