Is Hidden Cameras in Your Home Legal in Montana After the 2026 Law Changes?

Yes, Hidden cameras are legal in Montana under specific conditions. Montana law permits surveillance in private residences if at least one party (including the camera owner) consents, aligning with the state’s one-party consent statute. However, placing cameras in areas where privacy is expected—such as bathrooms or bedrooms—violates Montana’s wiretapping laws, which prohibit recording audio without consent. The Montana Attorney General’s Office enforces these rules, and violations may result in civil penalties or criminal charges. Local ordinances, such as those in Bozeman or Missoula, may impose additional restrictions, particularly regarding short-term rentals or shared housing.

Key Regulations for Hidden Cameras in Your Home in Montana

  • One-Party Consent Requirement: Montana Code Annotated § 45-8-213 mandates that only one party in a conversation must consent to audio recording. Hidden cameras without audio recording are generally permissible, but audio capture requires explicit consent from all recorded individuals.
  • Prohibition in Private Spaces: Installing hidden cameras in bathrooms, bedrooms, or other areas where individuals have a reasonable expectation of privacy is illegal under Montana’s invasion of privacy statutes (§ 45-2-302). Violations may lead to misdemeanor charges.
  • Short-Term Rental and Tenant Restrictions: Cities like Bozeman and Missoula have enacted ordinances requiring landlords and short-term rental hosts to disclose surveillance devices. Failure to comply may result in fines or lease termination under local housing codes.
