Adopt updates to building and energy codes

Nebraska's LB 801 updates the state's building and energy codes by adopting the 2024 editions of the International Building Code (IBC) and International Residential Code (IRC), while maintaining some exceptions from older versions. This bill directly affects local governments (counties, cities, and villages) that enforce building codes, requiring them to adopt these updated standards within two years or have the state code automatically apply. Key provisions include mandating that local codes conform generally to the state code, requiring notification to the Department of Water, Energy, and Environment for certain code changes, and specifying that radon-resistant construction standards must meet existing state requirements. The bill does not create new local code options but updates the baseline for all local building and energy regulations across Nebraska.
