Arkansas Building Code: Which Editions Are Adopted

Which I-Code editions Arkansas is recorded as adopting, what the record does not cover, and how to confirm the edition governing a project.

Last updated October 1, 2026 · Adopted editions transcribed from the [ICC Master I-Code Adoption Chart (January 2024)](https://www.iccsafe.org/wp-content/uploads/Master-I-Code-Adoption-Chart-1.pdf), reproduced with the chart's own legend so an “X” is not mistaken for a statewide adoption. ICC notes that not all jurisdictions report their adoptions and publishes updates at [iccsafe.org/adoptions](https://www.iccsafe.org/adoptions). The current edition, its effective date and the state amendments are published by [Arkansas State Fire Marshal (Arkansas Department of Public Safety)](https://media.ark.org/dps/ASP-Foreword-Fire-Code-Rules-Redlined_10-2024.pdf), which controls.

Direct answer

2021 Arkansas Fire Prevention Code (building, residential and fire volumes), effective 1 January 2023 in Arkansas. 2021 IFC, IBC and IRC with Arkansas amendments, published by the State Fire Marshal as Volumes I–III of the Arkansas Fire Prevention Code. The Arkansas Fire Prevention Code is the statewide minimum, but day-to-day enforcement depends on cities and counties adopting it by local ordinance, which the State Fire Marshal encourages. Record the permit application date with it: a code change normally applies from an effective date, and an application filed before that date is usually reviewed under the previous edition. This was checked on 2026-10-01 against Arkansas State Fire Marshal (Arkansas Department of Public Safety), which is the source that controls. The cross-state comparison further down this page comes from the ICC adoption chart dated January 2024, so where the two disagree the record above is the newer one.

The cross-state record

For comparison across states, every I-Code the ICC Master I-Code Adoption Chart (January 2024) tracks, as it records Arkansas. Where this disagrees with the record above, the record above is newer:

CodeRecorded adoption

International Residential Code (IRC)2021
International Fire Code (IFC)2021
International Mechanical Code (IMC)2021
International Plumbing Code (IPC)2018

ICC Performance Code (ICCPC)Not adopted
International Wildland-Urban Interface Code (IWUIC)Not adopted
International Zoning Code (IZC)Not adopted
ICC 700 National Green Building Standard (ICC 700)Not adopted

Arkansas has a recorded edition year for 8 of the 17 codes: 2021 for the building, residential, fire and mechanical codes; 2018 for the plumbing and fuel gas codes; 2009 for the residential energy and commercial energy codes. The property maintenance and existing buildings codes appear as adopted by individual state or local agencies rather than as a statewide standard, so whether they apply depends on the permit jurisdiction for the project address. No adoption at all is recorded for the private sewage, green construction, swimming pool and spa, performance, wildland-urban interface, zoning and green building standard codes.

How Arkansas compares with its neighbours

StateBuilding (IBC)Residential (IRC)Residential energy (IECC-R)

MissouriLocalLocalLocal
Tennessee2021 (limited)2018 (limited)2018 (limited)

Louisiana202120212021

Statewide editions in force, checked 2026-10-01; “Local” means no state adoption, “(limited)” a state adoption for some buildings only, and * a state-titled code built on that edition.

Missouri, Tennessee, Mississippi and Louisiana differ from Arkansas on the building code alone. A practice working across that border is working to two editions, whatever the office standard says.

Where Arkansas sits in the national record

Of the 50 states and the District of Columbia, 17 enforce the 2021 IBC statewide, 10 a later edition, 7 an earlier one, and 17 have no statewide IBC edition in force. Arkansas is at or ahead of the national middle on the building code, so the risk runs the other way: work arriving from a slower-moving state may be drawn to an older edition.

The residential code and the residential energy code are on different editions here — 2021 against 2009. 7 states show a split like this, which is why the energy code is worth confirming as a separate question rather than assuming it moved with the residential code.

Across all 17 codes the January 2024 ICC chart tracks, Arkansas has a recorded edition for 8, which ranked it 20th of 51. A low count is not a gap in regulation — it usually means the state legislates through its own documents, or leaves the discipline to local adoption.

What the chart does and does not tell you

The chart's own legend matters more than the numbers:

  • An edition year means one or more state or local agencies adopted that edition. It does not mean every building in the state is designed to it.
  • “Some jurisdictions only” is the chart's X: the code is in use somewhere in the state but is not the standard for all buildings.
  • “Not adopted” is a blank cell — no state or local jurisdiction reported adopting that code.
  • “State-written code” means the state publishes its own document in place of the model edition, so the model text is a reference, not the law.

ICC states plainly that not every jurisdiction notifies it of an adoption, and this chart is dated January 2024. Treat it as the starting point for a search, never as the answer.

How to confirm the edition that governs a Arkansas project

  1. Open Arkansas State Fire Marshal (Arkansas Department of Public Safety) and find the currently adopted code list with its effective date.
  2. Check whether the permit authority for the project address is the state or a local programme with its own adoption.
  3. Read the state amendments alongside the model edition — an amended table or definition changes the requirement even when the edition matches.
  4. Record the permit application date. A code change usually applies from an effective date, and applications filed before it are normally reviewed under the previous edition.
  5. Get the answer in writing from the authority having jurisdiction before it drives a design decision.

Arkansas code-basis worksheet

Fill this in once per project and keep it with the drawing set. Every row is a question a plan reviewer can ask, and the answer changes with the address and the application date, not with the state.

ItemProject entry
Project address and permit jurisdiction
State programme or local programme as AHJ
Building / residential edition and effective date
Energy code edition (or state-written code)
Fire, mechanical, plumbing and fuel-gas editions

This worksheet records a determination; it does not make one. The authority having jurisdiction decides which edition and which amendments apply.

The adoption above was checked on 2026-10-01 against Arkansas State Fire Marshal (Arkansas Department of Public Safety), the source that controls. The cross-state table comes from the ICC Master I-Code Adoption Chart (January 2024), which is older, so where the two disagree the checked record is the one to use.
