Heyburn, Idaho has adopted: 2018 International Residential Code (IRC), with Idaho amendments — per Heyburn's own Residential Home Permit Application Plan Submittal Requirements: 'Plans to be designed to the 2018 IRC Code & 2018 IECC. (with Idaho amendments)' (heyburn.id.gov, 2023 Residential New Home Permit application, page 2).; 2018 International Energy Conservation Code (IECC), with Idaho amendments — same source as above.; 2018 International Building Code (IBC), with amendments — Heyburn City Code Title 2, Chapter 1, Section 2-1-1(A) adopts by reference 'the following recognized codes as currently adopted by the State of Idaho,' and the State of Idaho's own currently-published adopted-codes list (Idaho DOPL, 'Idaho Adopted Codes,' dopl.idaho.gov/wp-content/uploads/2025/06/2025-Updated-Idaho-Adopted-Codes.pdf) lists the 2018 IBC with amendments as the current state building code.; 2018 International Existing Building Code (IEBC) — per the same Idaho DOPL 'Idaho Adopted Codes' publication, incorporated into Heyburn's code by the automatic state-code-reference mechanism in Heyburn City Code 2-1-1(A).; 2018 International Mechanical Code (IMC) and 2018 International Fuel Gas Code (IFGC) — per the same Idaho DOPL 'Idaho Adopted Codes' publication.; 2017 Idaho State Plumbing Code (based on the 2015 Uniform Plumbing Code) — per the same Idaho DOPL 'Idaho Adopted Codes' publication.; 2023 National Electrical Code (NEC), with amendments — per the same Idaho DOPL 'Idaho Adopted Codes' publication.; IMPORTANT — code-adoption mechanism: Heyburn City Code 2-1-1(A) (amd. Ord. 2026-721, 3-25-2026; Ord. 2026-722, 4-22-2026; codelibrary.amlegal.com/codes/heyburnid/latest/heyburn_id/0-0-0-15510) states verbatim: 'The following recognized codes as currently adopted by the State of Idaho are adopted as the official building codes of the City of Heyburn. Each code shall be deemed superseded by successive versions of such codes as they are adopted or approved by the State of Idaho effective on the 1st day of January the year following the date any such codes are made effective for the State of Idaho, unless a different date is required by state statute.' This means Heyburn's adopted editions track the State of Idaho's current adopted editions automatically, rather than being independently re-adopted by city ordinance edition-by-edition. The city's own 2023-dated Residential and Commercial permit application PDFs both independently confirm the 2018 IRC/2018 IECC editions currently in force, consistent with the state list.; NOTE: No Heyburn-specific local amendment TEXT to the IRC/IBC (e.g., a snow-load or seismic design value table, or textual deviations from the model code sections) was found published separately from the state-level amendments referenced above, as of 2026-07-04. Omitted rather than invented.. Local amendments apply — see the Heyburn overview page for the full list.
