Codes adopted

Idaho adopts a statewide baseline building code set under the Idaho Building Code Act (Idaho Code Title 39, Chapter 41) and IDAPA rules administered by the Idaho Division of Occupational and Professional Licenses (DOPL). Effective January 1, 2021, the statewide baseline includes the 2018 International Building Code (IBC), 2020 Idaho Residential Code (based on the 2018 IRC Parts I–III and IX with Idaho amendments), 2020 Idaho Energy Conservation Code (based on the 2018 IECC with Idaho amendments), 2018 International Existing Building Code (IEBC), 2018 International Mechanical Code (IMC), 2018 International Fuel Gas Code (IFGC), and 2018 International Fire Code (IFC). The National Electrical Code is adopted separately by the Idaho Electrical Board (IDAPA 24.39.10), not bundled with the building code: Idaho enforces the 2023 NEC, effective July 1, 2024 (the state used the 2017 NEC with amendments before that and skipped the 2020 edition). Local jurisdictions must enforce the state baseline and may adopt amendments only where those amendments are at least as stringent as the state-adopted editions; local amendments may not be less restrictive. Enforcement is local — each city or county issues permits and performs inspections. Always confirm the current adopted edition and any local amendments with your specific jurisdiction before submitting plans.

• 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.

Permit types & fees

• Residential Home Permit (New Construction — Single Family, Duplex, Zero Lot Line, Townhouse)

  Required for new single-family dwellings, duplexes, zero-lot-line homes, and townhouses (separate site-only permit required for townhouses) in the City of Heyburn. Governed by the 2018 IRC and 2018 IECC (with Idaho amendments) per the city's own Residential Home Permit Application. Manufactured and modular homes use a separate application.

  →

• New or Addition Commercial Building Permit (Commercial/Non-Residential/Multi-Family)

  Required for new complete buildings, additions, multi-family (3+ dwelling units), and shell buildings (with or without interior walls) in the City of Heyburn. A pre-submittal meeting is required on all new and addition commercial projects. Governed by the state-referenced 2018 IBC per Heyburn City Code 2-1-1(A).

  →

• Solar Photovoltaic (PV) Permit

  Required for installation of rooftop or ground-mount solar photovoltaic systems within Heyburn city limits. Requires a City Building Permit (structural/racking, valuation-based on Project Value per the City's Residential Home Permit Application) plus a State of Idaho electrical permit (wiring/interconnection) issued by the Division of Occupational and Professional Licenses (DOPL) -- Heyburn's own Residential Home Permit Application states directly that 'Additional permits are required for electrical, plumbing and mechanical installations,' and electrical work in Heyburn is handled by the state, not the City. The state's Contractor Electrical Permit Worksheet has a dedicated checkbox and valuation-based fee formula for 'Solar, Renewable Energy, power generation, power production, or energy storage systems.'

  →

• EV Charger / EVSE Permit

  Heyburn has no dedicated EV charger or EVSE permit and no distinct fee line item for electric vehicle charging equipment. Unlike solar/renewable-energy installations (which require both a City structural Building Permit and a State electrical permit), a standard EV charger is not a power-generation or energy-storage system and involves no structural/racking work, so it does not trigger the City's Residential Home Permit. The wiring/circuit work is billed as a standard electrical installation under the State of Idaho DOPL Contractor (or Homeowner) Electrical Permit, since Heyburn's own permit application states directly that 'Additional permits are required for electrical, plumbing and mechanical installations' and the City has no electrical-permit program of its own -- using the general 'Other Installations including Commercial/Industrial/Solar/Renewable Energy' valuation-based fee formula (the same formula used for solar, just without the Solar/Renewable Energy checkbox).
