Recording Law for Employers & Businesses in Minnesota

Minnesota lets you record any conversation you are part of without telling the other person. This is called one‑party consent. The rule comes from Minn. Stat. § 626A.02, which permits interception of a wire, electronic, or oral communication where the person is a party to the communication or one of the parties has given prior consent. The statute covers phone calls, texts, and in‑person spoken exchanges, but Minnesota’s definition of "oral communication" includes a built‑in privacy test: the speaker must actually expect the conversation won’t be overheard and the circumstances must justify that expectation. If someone is shouting in a crowd, that expectation isn’t justified; if they’re huddled in a quiet corner, it may be. The one‑party rule applies the same whether the conversation happens in your office, a customer’s home, or on the street. Violating the rule can lead to a felony punishable by up to five years imprisonment and a fine of up to $20,000; a gross misdemeanor punishable by up to 364 days imprisonment and a fine of up to $3,000; or a petty offense punishable by a fine of up to $500, depending on the facts.

If your smartglasses or camera capture video without recording audio, Minnesota places no consent requirement on that video. The wiretap statute only regulates the "aural or other acquisition of the contents" of a wire, electronic, or oral communication. A silent video of what people do or where they go is not regulated by Minn. Stat. ch. 626A. Be careful, though: a separate law, Minn. Stat. § 609.746, makes it a crime to secretly photograph or record someone in a private space like a bathroom, locker room, or someone else’s home through a window. That law protects other people’s privacy in those specific settings, not your right to openly document public interactions.

Minnesota does not prohibit recording on‑duty police in public. The Eighth Circuit has noted in dicta that every federal appeals court to have considered the question has recognized a First Amendment right to record police activity in public, and reasoned that if recording is protected, so is mere observation. However, in Molina v. Book, a divided panel held that the right to observe or record police‑citizen interactions was not "clearly established" as of 2015, so qualified immunity barred the plaintiffs’ damages claims. Another decision, Akins v. Knight, arose from recording in a police station lobby and is narrower. The result is real uncertainty: recording police in public is not itself illegal under Minnesota’s wiretap law, but the federal courts have not fully settled whether officers can be held liable for interfering with your recording. If an officer directs you to stop recording, the safest practice is to pause and ask whether you are free to leave.

Minnesota’s privacy law treats biometric data, including voiceprints, as "sensitive data" that cannot be processed without the person’s consent. The Minnesota Consumer Data Privacy Act (MCDPA) defines biometric data to include a voiceprint and says a controller may not process sensitive data concerning a consumer without obtaining the consumer’s consent. Consent must be freely given, specific, informed, and unambiguous—it cannot be obtained via broad terms‑of‑use acceptance, dark patterns, or passive acts like hovering, muting, or closing a notice. If you enroll employees or customers into a voiceprint system to identify them, you must obtain clear consent up front and provide an easy way to revoke it, with processing to cease as soon as practicable, but no later than 15 days after receipt of the request. The Attorney General enforces this law, not private lawsuits, and the law only applies if you control or process personal data of at least 100,000 Minnesota consumers a year or control or process 25,000 or more consumers’ data and derive more than 25% of gross revenue from the sale of personal data.

Imagine a store employee wearing smartglasses documents a loud argument between two customers in the parking lot. The customers are shouting at normal volume and no one asks to stop recording. Under Minnesota’s one‑party consent rule, the employee can keep recording because they are part of the conversation and the circumstances do not clearly justify a privacy expectation. If the same argument moves into a quiet corner of the store where the customers lower their voices and step apart from other shoppers, the employee should pause or move back to avoid capturing a conversation that may carry a justified expectation of privacy. If the store later uses a voiceprint system to recognize frequent shoppers who opt in, it must obtain clear consent and allow opt‑out.

Recording a conversation without consent can lead to a felony punishable by up to five years imprisonment and a fine of up to $20,000; a gross misdemeanor punishable by up to 364 days imprisonment and a fine of up to $3,000; or a petty offense punishable by a fine of up to $500, depending on the facts. The law also allows a private right of action under Minn. Stat. § 626A.13, so someone you record could sue you for damages. Minnesota’s biometric rules are enforced by the Attorney General, with civil penalties up to $7,500 per violation and a 30‑day warning period that expires January 31, 2026. The MCDPA does not allow private lawsuits, so only the state can pursue claims under that law.
