Neb. Rev. Stat. § 18-1915
The State of Nebraska shall permit cities and villages to collect permit fees and inspect all sanitary plumbing installed or repaired, except for a single-family dwelling or a farm or ranch structure, within the State of Nebraska outside of the corporate limits or extraterritorial zoning jurisdiction of cities and villages. The city or village nearest the construction site shall have jurisdiction to collect such permit fees and conduct the inspection of the sanitary plumbing. If such city or village has a plumbing ordinance in force and effect, such ordinance will govern the installation of the sanitary plumbing. If there is no plumbing ordinance in effect for such city or village, the 2018 Uniform Plumbing Code designated by the American National Standards Institute as an American National Standard shall apply to all buildings except single-family dwellings and farm and ranch structures.
