Working notes

SCOPE NOTE from the statute scheme: NDCC ch. 43-18 licensing applies to plumbing businesses in locations having a public system of waterworks or sewerage (NDCC 43-18-11, as quoted in Attorney General Opinion 97-F-12) - the state regime is statewide in structure but keyed to publicly served locations. Rule history in the official Admin. Code text: effective March 1, 2000; amended effective April 1, 2010 and April 1, 2020 (the 2020 amendment adopted the 2018 edition and renamed the code the North Dakota Plumbing Code). Board exams are open-book on the 2018 North Dakota Plumbing Code.
