Are North Dakota businesses allowed to put cameras in bathrooms?

No.
North Dakota law prohibits businesses and individuals from installing cameras in restrooms or other places where people reasonably expect privacy.

Under North Dakota Century Code § 12.1-20-12.2, it is a crime to record, photograph, observe or broadcast someone in a bathroom, hotel room, dressing room, locker room, tanning booth or similar private space without their consent. This offense, called surreptitious intrusion, is a Class A misdemeanor for a first violation. It can be charged as a Class C felony if the person has a prior conviction or if the victim is a minor.
Businesses may legally use video surveillance in areas where there is no reasonable expectation of privacy, such as entrances, sales floors or parking lots. However, surveillance in bathrooms or other private spaces is strictly prohibited and can result in both criminal charges and civil liability.
