Kansas Building Code: Which Editions Are Adopted

Direct answer

No statewide commercial building code; only the Kansas Fire Prevention Code is mandatory statewide in Kansas. Cities and counties adopt their own building and residential codes, typically from an IBC or IRC edition; the state fire code adopts the 2006 IFC and related NFPA standards by reference. The State Fire Marshal has announced it intends to start rulemaking to replace the fire code with the 2024 International Fire Code, Kansas Edition, developed with the Governor's Uniform Fire Code Task Force. No formal proposed regulation has been published yet. 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 Kansas State Fire Marshal, 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.

Which codes has Kansas adopted now?

No statewide commercial building code; only the Kansas Fire Prevention Code is mandatory statewide.

Cities and counties adopt their own building and residential codes, typically from an IBC or IRC edition; the state fire code adopts the 2006 IFC and related NFPA standards by reference.

Transition: The State Fire Marshal has announced it intends to start rulemaking to replace the fire code with the 2024 International Fire Code, Kansas Edition, developed with the Governor's Uniform Fire Code Task Force. No formal proposed regulation has been published yet.

Local adoption: Local jurisdictions adopt and enforce their own building, residential and energy codes and may amend the state fire code to be more stringent. State law names the 2006 IECC as the energy efficiency standard for new commercial and industrial buildings but gives no state agency power to enforce it. Projects on state-owned property follow the codes enforced by the Kansas Department of Administration.

The cross-state record

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

The building, residential, fire, mechanical, plumbing, private sewage, fuel gas, residential energy, commercial energy, property maintenance, existing buildings and swimming pool and spa 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 green construction, performance, wildland-urban interface, zoning and green building standard codes.

How Kansas compares with its neighbours

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.

Nebraska, Oklahoma and Colorado differ from Kansas on the building code alone. A practice working across that border is working to two editions, whatever the office standard says.

Where Kansas sits in the national record

Kansas is one of 17 jurisdictions with no statewide IBC edition in force. Adoption runs through local programmes or applies only to a subset of buildings, so there is no single answer for the state and the permit jurisdiction for the address decides.

Kansas is one of 15 jurisdictions with no statewide residential energy code based on an IECC edition in force, so the energy question is answered by the state's own document or by the local jurisdiction.

Across all 17 codes the January 2024 ICC chart tracks, Kansas has a recorded edition for 0, which ranked it 50th 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 Kansas project

1. Open Kansas State Fire Marshal 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.

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.

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

Sources and method

Adopted editions transcribed from the ICC Master I-Code Adoption Chart (January 2024), 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. The current edition, its effective date and the state amendments are published by Kansas State Fire Marshal, which controls.
