Boulder City, Nevada has adopted: Nevada has no mandatory statewide building code; NRS 701.220 requires the Nevada Governor's Office of Energy (GOE) to adopt, on a triennial basis, the most recently published International Energy Conservation Code (IECC) as a statewide ENERGY floor only — local governments may not adopt an energy code less stringent than the GOE-adopted IECC edition, but building-code editions for structural/life-safety codes vary city-by-city under home rule. The 2024 IECC was adopted by the GOE effective August 18, 2024, as the current statewide energy floor. Source: NRS 701.220 (Nevada Revised Statutes, Chapter 701 — Energy Policy), https://www.leg.state.nv.us/nrs/nrs-701.html; Nevada Governor's Office of Energy, Building Energy Codes / State Adoption Status, https://www.energy.nv.gov/programs/building-energy-codes/state-adoption-status/. Confirm your city's specific adopted energy-code edition — Boulder City's own adopted edition is documented separately below and is older than the current statewide floor edition (a home-rule city choice, not a floor violation, since IECC 2018 was the floor at the time of Boulder City's last code-cycle adoption).; Boulder City runs its own independent building-permit program (Community Development Department, Building and Safety Division) — it is NOT administered by Clark County.
