Minn. Stat. § 97C.355
Subd. 1. Identification required.
All shelters on the ice of state waters, including dark houses and fish houses, must have: (1) the owner's name and address, (2) the owner's driver's license number, or (3) the "MDNR#" license identification number issued to the owner legibly displayed on the exterior with characters at least two inches high.
Subd. 2. License required.
A person may not leave a dark house or fish house unattended on the ice at any time between midnight and one hour before sunrise unless the house is licensed and has a license tag attached to the exterior in a readily visible location, except as provided in this subdivision. The commissioner must issue a tag with a dark house or fish house license, marked with a number to correspond with the license and the year of issue. A dark house or fish house license is not required of a resident on boundary waters where the adjacent state does not charge a fee for the same activity.
Subd. 3. Door must open from outside.
A person may not use a dark house or fish house unless the door is constructed so that it can be opened from the outside when it is in use.
Subd. 4. Distance between houses.
A person may not erect a dark house, fish house, or shelter within ten feet of an existing dark house, fish house, or shelter.
Subd. 5. Burning of structures.
A person may not burn a structure on the ice of state waters without permission of the commissioner. The commissioner may allow burning only after determining that the structure cannot be removed from the ice by another reasonable manner. The owner must remove the remains of the burned structure from the ice.
Subd. 6.

A shelter, including a fish house or dark house, on the ice in violation of this subdivision is subject to the enforcement provisions of paragraph (b). The commissioner may, by rule, change the dates in this paragraph for any part of state waters. Copies of the rule must be conspicuously posted on the shores of the waters as prescribed by the commissioner.
