West Virginia Building Code: Which Editions Are Adopted

Which I-Code editions West Virginia 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 [West Virginia State Fire Commission](https://apps.sos.wv.gov/adlaw/csr/rule.aspx?rule=87-04), which controls.

Direct answer

2018 West Virginia State Building Code, effective 1 August 2022, in force only where a county or city adopts it in West Virginia. 2018 IBC, IRC, IEBC, IPC, IMC, IFGC and IPMC, the 2015 IECC for homes and ASHRAE 90.1-2013 for commercial buildings, adopted by the State Fire Commission as legislative rule 87CSR4. An amended rule that would move the State Building Code to the 2024 I-Codes, the 2024 IECC and ASHRAE 90.1-2019 was approved by the State Fire Commission in July 2026 and still needs legislative authorisation. The current rule is set to expire on 1 August 2027. This was checked on 2026-10-01 against West Virginia State Fire Commission, 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 West Virginia adopted now?

2018 West Virginia State Building Code, effective 1 August 2022, in force only where a county or city adopts it.

2018 IBC, IRC, IEBC, IPC, IMC, IFGC and IPMC, the 2015 IECC for homes and ASHRAE 90.1-2013 for commercial buildings, adopted by the State Fire Commission as legislative rule 87CSR4.

DisciplineAdopted

Commercial energyASHRAE 90.1-2013
Existing buildings2018 IEBC
FireState Fire Code: NFPA 1 and NFPA 101, 2021 editions (statewide)

Transition: An amended rule that would move the State Building Code to the 2024 I-Codes, the 2024 IECC and ASHRAE 90.1-2019 was approved by the State Fire Commission in July 2026 and still needs legislative authorisation. The current rule is set to expire on 1 August 2027.

Local adoption: Counties and municipalities choose whether to adopt the State Building Code; those that do enforce it and must notify the State Fire Commission. The separate State Fire Code, based on NFPA 1 and NFPA 101 (2021 editions), applies statewide.

Checked 2026-10-01 against West Virginia State Fire Commission. Confirm the edition and effective date for the specific permit jurisdiction before relying on it.

The cross-state record

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

West Virginia has a recorded edition year for 9 of the 17 codes: 2018 for the building, residential, mechanical, plumbing, fuel gas, property maintenance, existing buildings and swimming pool and spa codes; 2015 for the residential energy code. For the commercial energy code the chart records ASHRAE 90.1-2013 in place of an IECC edition. No adoption at all is recorded for the fire, private sewage, green construction, performance, wildland-urban interface, zoning and green building standard codes.

How West Virginia compares with its neighbours

StateBuilding (IBC)Residential (IRC)Residential energy (IECC-R)
West Virginia2018 (limited)2018 (limited)2015 (limited)
Virginia2021*2021*2021*
Ohio2021*2018*2018*
Pennsylvania202120212021
Kentucky2015*2015*2009

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.

Virginia, Ohio, Pennsylvania and Kentucky differ from West Virginia on the building code alone. A practice working across that border is working to two editions, whatever the office standard says.

Where West Virginia sits in the national record

West Virginia 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.

West Virginia 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, West Virginia has a recorded edition for 9, which ranked it 12th 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 West Virginia project

  1. Open West Virginia State Fire Commission 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.

This site also hosts a transcription of the 2009 model code chapters as adopted in West Virginia at /building-codes/us-states/west-virginia. That is a historical reference for the 2009 editions and is not West Virginia's current code basis.

West Virginia 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
Accessibility standard and edition
State amendments consulted (citation)
Local amendments consulted (citation)
Permit application date and vesting rule
Written AHJ confirmation (date, name)

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 West Virginia State Fire Commission, which controls.

Frequently asked questions

Which building code edition does West Virginia use?

2018 West Virginia State Building Code, effective 1 August 2022, in force only where a county or city adopts it. 2018 IBC, IRC, IEBC, IPC, IMC, IFGC and IPMC, the 2015 IECC for homes and ASHRAE 90.1-2013 for commercial buildings, adopted by the State Fire Commission as legislative rule 87CSR4. This was checked on 2026-10-01 against West Virginia State Fire Commission; confirm the edition and effective date for the permit jurisdiction before relying on it.

How current is this record?

The adoption above was checked on 2026-10-01 against West Virginia State Fire Commission, 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.
