North Dakota Century Code Title 20.1. Game, Fish, Predators, and Boating § 20.1-06-07. Fishhouses--Removal--Penalty

1. A person may erect, have, or maintain on the ice in any waters of this state a fishhouse, used or to be used while ice fishing, or a dark house, used or to be used for spearfishing. Fishhouse and dark house owners are subject to the rules the director may adopt governing the construction, maintenance, and use of these units. The outside of each unoccupied unit must have inscribed on it, in readily distinguishable characters at least three inches [7.62 centimeters] high, the registration number issued by the department for the fishhouse, or the owner's name and address or telephone number. An unoccupied fishhouse or dark house left on the ice without a registration number, or an owner's name and address or telephone number may be removed or destroyed by the department. The department may not issue a fishhouse registration number, unless the division of state radio has integrated game and fish department license information into the national law enforcement telecommunications system. Any person who violates this subsection is guilty of a class 2 noncriminal offense.

2. Each unit must be removed from the ice by that date established by the governor's proclamation. Failure to remove a unit is deemed an abandonment and the director may remove or destroy abandoned units.
