US Building Code Adoption by State
Nevada Building Code: Which Editions Are Adopted
Which I-Code editions Nevada 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 [Nevada Governor's Office of Energy](https://energy.nv.gov/Programs/Building_Energy_Codes/State_Adoption_Status), which controls.
Direct answer
2024 IECC adopted statewide effective 18 August 2024; building codes are otherwise adopted locally in Nevada. The Governor's Office of Energy must adopt the latest IECC every three years as the statewide energy minimum (NRS 701.220); state-owned buildings follow the 2024 I-Codes adopted by the State Public Works Board, and the State Fire Marshal adopts the 2024 IFC and IBC for fire and life safety. The State Public Works Division's 2024 codes for state-owned land took effect on 15 November 2024; projects designed to the 2018 codes had a six-month grace period. The State Fire Marshal's update from the 2018 to the 2024 International Fire Code was filed on 27 February 2026, and the Division announced it would enforce the 2024 codes from 1 January 2026. This was checked on 2026-10-01 against Nevada Governor's Office of Energy, 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 Nevada adopted now?
2024 IECC adopted statewide effective 18 August 2024; building codes are otherwise adopted locally.
The Governor's Office of Energy must adopt the latest IECC every three years as the statewide energy minimum (NRS 701.220); state-owned buildings follow the 2024 I-Codes adopted by the State Public Works Board, and the State Fire Marshal adopts the 2024 IFC and IBC for fire and life safety.
| Discipline | Adopted |
|---|---|
| Energy | 2024 IECC, statewide (ASHRAE 90.1-2022 commercial path) |
| Fire | 2024 IFC with Nevada amendments, State Fire Marshal (NAC 477.281) |
| State-owned buildings | 2024 IBC, IRC, IEBC and IECC adopted by the State Public Works Board |
| Building and residential | Local adoption; local codes must include the state energy standards |
Transition: The State Public Works Division's 2024 codes for state-owned land took effect on 15 November 2024; projects designed to the 2018 codes had a six-month grace period. The State Fire Marshal's update from the 2018 to the 2024 International Fire Code was filed on 27 February 2026, and the Division announced it would enforce the 2024 codes from 1 January 2026.
Local adoption: Cities and counties adopt their own building and residential codes and must incorporate the state energy standards, which they may exceed but not weaken. Clark County applies the Southern Nevada Amendments, which are more stringent than the model codes for life safety, fire protection and high-rise construction.

The cross-state record
For comparison across states, every I-Code the ICC Master I-Code Adoption Chart (January 2024) tracks, as it records Nevada. Where this disagrees with the record above, the record above is newer:
| Code | Recorded adoption |
|---|---|
| International Building Code (IBC) | Some jurisdictions only |
| International Residential Code (IRC) | Some jurisdictions only |
| International Fire Code (IFC) | Some jurisdictions only |
| International Mechanical Code (IMC) | Some jurisdictions only |
| International Plumbing Code (IPC) | Some jurisdictions only |
| International Private Sewage Disposal Code (IPSDC) | Some jurisdictions only |
| International Fuel Gas Code (IFGC) | Some jurisdictions only |
| International Green Construction Code (IgCC) | Not adopted |
| International Energy Conservation Code — Residential (IECC-R) | 2021 |
| International Energy Conservation Code — Commercial (IECC-C) | 2021 |
| International Property Maintenance Code (IPMC) | Some jurisdictions only |
| International Existing Building Code (IEBC) | Some jurisdictions only |
| International Swimming Pool and Spa Code (ISPSC) | Some jurisdictions only |
| ICC Performance Code (ICCPC) | Some jurisdictions only |
| International Wildland-Urban Interface Code (IWUIC) | Some jurisdictions only |
| International Zoning Code (IZC) | Not adopted |
| ICC 700 National Green Building Standard (ICC 700) | Not adopted |
Nevada has a recorded edition year for 2 of the 17 codes: 2021 for the residential energy and commercial energy codes. The building, residential, fire, mechanical, plumbing, private sewage, fuel gas, property maintenance, existing buildings, swimming pool and spa, performance and wildland-urban interface 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, zoning and green building standard codes.

How Nevada compares with its neighbours
| State | Building (IBC) | Residential (IRC) | Residential energy (IECC-R) |
|---|---|---|---|
| Nevada | 2024 (limited) | 2024 (limited) | 2024 |
| California | 2024* | 2024* | State code |
| Arizona | Local | Local | Local |
| Utah | 2024 | 2021 | State code |
| Oregon | 2024* | 2024* | State code |
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.
California, Arizona, Utah and Oregon differ from Nevada on the building code alone. A practice working across that border is working to two editions, whatever the office standard says.
Where Nevada sits in the national record
Nevada 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.
Across all 17 codes the January 2024 ICC chart tracks, Nevada has a recorded edition for 2, which ranked it 46th 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 Nevada project
- Open Nevada Governor's Office of Energy and find the currently adopted code list with its effective date.
- Check whether the permit authority for the project address is the state or a local programme with its own adoption.
- Read the state amendments alongside the model edition — an amended table or definition changes the requirement even when the edition matches.
- 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.
- Get the answer in writing from the authority having jurisdiction before it drives a design decision.
Nevada 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.
| Item | Project 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 Nevada Governor's Office of Energy, which controls.
