Who oversees Registration: Contractors are regulated by the Nebraska Department of Labor.  

Procedures for Registering:   You can start the application online at the Department of Labor.

Fees:  There are fees to register.

Applicable Code:  Local municipalities of Nebraska have adopted the International Plumbing Code established by the International Code Council.
