State Adoption Status

Adoption of the 2021 IECC

Pursuant to NRS 701.220, the Governor's Office of Energy (GOE) is required to adopt the most recently published version of the International Energy Conservation Code (IECC) on a triennial basis. Upon adoption by GOE, local municipalities shall follow suit and are authorized to adopt amendments and/or provisions which are more stringent then the standards published and adopted.

GOE has adopted the 2021 IECC as published with additional optional Electric Vehicle (EV) ready appendices, effective July 28, 2021. These appendices will allow local municipalities to use nationally vetted provisions for the adoption of EV ready codes if the municipality chooses to do so. The EV provisions are not mandatory.

Energy Codes and Climate

As identified in the Nevada Climate Strategy, development and adoption of the energy codes can be instrumental in achieving Nevada’s climate goals. The IECC is developed on a triennial schedule through a fair, robust process that includes building officials, national builders, state government officials, and others that are responsible for the adoption of the codes. During the 2021 IECC development and adoption process, the Nevada Governor’s Office of Energy (GOE) participated along with the Nevada Division of Environmental Protection (NDEP) in the public comment hearings in Las Vegas and the online vote. Both processes requiring voting members to qualify under the International Code Council Policies as defined in Council Policy 28.

According to the U.S Department of Energy (DOE), energy codes are projected to save U.S. homes and businesses $126 billion between 2012 and 2040. These numbers were calculated with the assumption that new, updated codes would continue to be adopted.
