In 2009, Nevada underwent a significant legislative shift that fundamentally altered the process of adopting building codes throughout the state. Prior to this change, the statewide building code applied only to local jurisdictions that had not yet adopted any building code, even if those codes were less stringent. The reform in 2009 expanded the reach of the statewide code, now encompassing all jurisdictions. However, a notable flexibility was introduced—local governments retained the authority to adopt more rigorous building codes, provided they communicated such decisions to the Office of Energy.
Before this legislative change, the applicable building code, in effect since July 1, 2015, made reference to the 2012 International Energy Conservation Code (IECC) and the ASHRAE 90.1-2007. Fast forward to the present, the current building code in Nevada, effective since June 26, 2018, features the 2018 IECC with state-specific amendments for residential structures. Commercial buildings, on the other hand, adhere to the 2018 IECC and ASHRAE 90.1-2016.
A notable commitment to staying abreast of advancements in energy efficiency is highlighted by state law, mandating that the Nevada State Energy Office must promulgate the most recent version of the IECC every three years. This emphasis on regular updates underscores Nevada’s dedication to modern and energy-efficient building standards, reflecting a proactive approach to sustainable development in the realm of construction and energy consumption.
