Current Residential Code
  • City of Las Vegas and other Southern Nevada jurisdictions currently use the 2018 International Residential Code (IRC), which is set to transition to the 2024 IRC in upcoming updates.
  • Clark County also operates under the 2018 IRC, which includes local amendments to suit specific regional requirements.

These codes ensure residential buildings meet modern safety, energy efficiency, and construction standards. Transition to the 2024 codes is planned in response to newer standards released by the International Code Council.

Enforcement

The Nebraska Energy Code, codified in Nebraska Administrative Code Title 107, is mandatory for all jurisdictions enforcing an energy code. Local jurisdictions may adopt their own codes, but state law requires that these local codes be of equal or greater stringency to the current Nebraska Energy Code. If a town or county has not adopted an energy code or does not wish to adopt an energy code, the Nebraska Energy Office will enforce the code in that jurisdiction.

The code applies to new residential and commercial construction as well as renovations that will cost more than 50 percent of the replacement cost of the building. There are some exemptions from the code, including historic buildings, modular housing units, mobile homes, and renovations that will cost less than 50 percent of the replacement cost of the building.

Code Adoption and Change Process

Code Change Process

Legislative: In Nevada, the building code update process is handled primarily at the local level by county or city jurisdictions, such as Clark County or the City of Las Vegas. Before code updates are proposed, technical advisory committees and local building officials review existing codes and consider updates based on the latest editions of the International Codes. After development, these proposals are opened for public comment, allowing input from industry stakeholders, citizens, and other interested parties. Following this, the proposals undergo further review and, if necessary, revision before being submitted to a local governing body or regulatory board for final approval. Once approved, the new codes or amendments are officially adopted and set for implementation, typically including a transition period to allow the industry to adapt. Each jurisdiction might conduct this process with slight variations to reflect local needs and regulatory frameworks.

Code Change Cycle

No set schedule. Nevada jurisdictions, including Clark County and the City of Las Vegas, generally align with the three-year cycle of the International Code Council (ICC) for reviewing model code editions. However, it is up to the local technical advisory committees and regulatory boards to decide whether to update the local building codes based on these reviews.

Next Code Update

NEO has plans to review the latest editions of the model codes, but the likely timeline for this process is not clear.
