Nevada — Code Adoption Summary
Adoption model: Home-rule / county-based — no single statewide code for private construction; the state's own adoption (via Public Works Board) applies only to state-owned land. Regional adoption committees produce "blended" amendments that counties/cities then adopt locally.

State-owned-land code (Public Works Board — narrow scope)
| Code family | Adopted edition | Notes | Source |
|---|
| Building / Residential / Existing | 2024 IBC/IRC/IEBC | state-owned/funded buildings only | publicworks.nv.gov |
| Electrical (NEC) | NEC 2023 | state-owned scope | " |
| Plumbing / Mechanical | 2024 UPC / 2024 UMC | NV state scope = UPC | " |
| Energy | 2024 IECC + ASHRAE 90.1 | state scope; NV law requires statewide LOCAL adoption of the latest IECC (this part IS a real statewide mandate even though building/electrical are not) | energy.nv.gov |
Local adoption (the reality for nearly all private construction)
- Clark County (Las Vegas metro): adopted 2024 IBC, all new permits must demonstrate 2024 IECC compliance, effective 2026-01-11.
- Regional adoption committees prepare "blended" amendment packages; counties/cities then formally adopt locally — expect Clark, Washoe (Reno), and others to differ somewhat from each other and from the state scope table above.
Adoption model & precedence
- Energy code: the one family with a genuine statewide mandate (locals must adopt the latest IECC) — reasonably reliable to cite as current-ish, but confirm the exact edition locally.
- Everything else (building/electrical/plumbing/mechanical): local county/city is the AHJ — the state table above does NOT apply to private construction outside state-owned land.
Major cities / counties
| Jurisdiction | County | Notes | Building dept. |
|---|
| Las Vegas / Clark County | Clark | 2024 IBC + 2024 IECC, eff. 2026-01-11 — confirmed current | clarkcountynv.gov |
| Henderson | Clark | local adoption — confirm | cityofhenderson.com |
| North Las Vegas | Clark | local adoption — confirm | cityofnorthlasvegas.com |
| Reno | Washoe | local adoption — confirm | reno.gov |
AHJ fallback (when local adoption is unverified)
- Certain-ish floor: statewide mandate to adopt the latest IECC (energy only).
- Everything else: confirm directly with the county/city — Clark County is the best-documented (2024 IBC/IECC, eff. 2026-01-11); other counties may differ.
Change log
- 2026-07-03 — created; verified state-owned-land scope (NEC 2023, 2024 IBC/UPC/UMC/IECC) vs. Clark County's own 2024 IBC/IECC (eff. 2026-01-11); confirmed statewide IECC-adoption mandate.
