Change and provide limitations on updates to state and local building codes, electrical codes, and energy codes

LB 1134 establishes Nebraska's baseline building, electrical, and energy codes by adopting specific editions of international codes (like the 2018 International Building Code) as the state standard. It limits local governments from creating stricter codes than the state version, prohibiting updates to local codes that exceed the state code's requirements until 2031. The bill requires local governments to provide independent third-party evidence verifying that any code change is necessary for public safety or compliance with state/federal law, rather than for cost reduction. This directly affects counties, cities, and villages that enforce building codes, as well as construction businesses and property owners subject to these regulations.
