Virginia Building Code: Which Editions Are Adopted

Direct answer

2021 Virginia Uniform Statewide Building Code (USBC), effective 18 January 2024 in Virginia. 2021 I-Codes, incorporated by reference with Virginia amendments. Applications filed between 18 January 2024 and 17 January 2025 could use either the 2018 or the 2021 USBC; from 18 January 2025 all applications must meet the 2021 USBC. The Board of Housing and Community Development has begun updating the USBC to the 2024 model codes; that update has not yet been adopted. 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 Virginia Department of Housing and Community Development, 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 Virginia. Where this disagrees with the record above, the record above is newer:

Virginia has a recorded edition year for 11 of the 17 codes: 2021 for the building, residential, fire, mechanical, plumbing, fuel gas, residential energy, commercial energy, property maintenance, existing buildings and swimming pool and spa codes. No adoption at all is recorded for the private sewage, green construction, performance, wildland-urban interface, zoning and green building standard codes.

How Virginia 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.

Maryland, North Carolina, West Virginia and Tennessee differ from Virginia on the building code alone. A practice working across that border is working to two editions, whatever the office standard says.

Where Virginia 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. Virginia 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.

Across all 17 codes the January 2024 ICC chart tracks, Virginia has a recorded edition for 11, which ranked it 3rd 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 Virginia project

1. Open Virginia Department of Housing and Community Development 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 Virginia at /building-codes/us-states/virginia. That is a historical reference for the 2009 editions and is not Virginia's current code basis.

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 Virginia Department of Housing and Community Development, which controls.
