A public housing authority in Concord, New Hampshire, has drawn criticism and legal challenges after installing noise-monitoring devices in approximately 300 affordable housing units. The devices, known as Minut sensors, were introduced in 2024 to help enforce smoking bans and noise restrictions, aiming to address disturbances without relying solely on neighbor complaints.
The Minut sensors measure sound levels, motion, air quality, and Bluetooth signals but do not record audio or video. Officials emphasized that the devices are camera-free and do not listen to conversations. Residents received notices explaining these features when the installation began. However, tenants raised concerns about privacy and the extent of data collected, with some describing the sensors as intrusive or akin to surveillance.
One resident reported that her device was installed nearly directly above her bed, prompting her to cover it with foil and even place it in a freezer to block its sensing capabilities. Another tenant questioned the housing authority about monitoring movement inside her apartment, receiving an inaccurate assurance that the device did not track motion. Some families altered their behavior due to the monitor’s presence, including asking household members to keep noise down near the sensors.
Legal representatives from New Hampshire Legal Assistance and the American Civil Liberties Union became involved after residents sought clarity on the data collected. Public records requests revealed that the sensors generated hundreds of millions of data points, tracking sound and movement at minute intervals. Tenants expressed alarm at the volume and detail of information gathered, highlighting potential risks if such data became accessible to unauthorized parties.
One tenant, Terri King, whose monitor was installed in January, was fined $450 for allegedly tampering with the device after it detected multiple incidents of disruption. She and her husband received an eviction notice for failing to pay the fine, which was later rescinded following legal intervention. Ms. King and another resident subsequently filed a lawsuit against the Concord Housing and Redevelopment Authority, alleging unconstitutional government intrusion and warrantless searches. The suit seeks class action status and demands removal of the devices alongside deletion of collected data.
Nathan Wessler, an attorney with the ACLU representing the tenants, criticized the arrangement, stating that access to subsidized housing should not come at the cost of constant surveillance inside private homes. Conversely, Julie Palmeri, executive director of the Concord housing authority, denied claims of surveillance, asserting that the sensors are deployed solely to safeguard health, safety, and property standards.
Minut, a Sweden-based company that produces the sensors, confirmed that its technology is primarily marketed to short-term rental hosts as a non-intrusive way to monitor noise. Its chief executive, Nils Mattisson, acknowledged the novelty of the public housing application and said motion detection features were disabled after tenant objections in May. He emphasized that the noise data collected represents only average decibel levels and cannot reveal specific activities.
The dispute raises broader questions about privacy, data use, and tenant rights in subsidized housing, as technology increasingly becomes part of property management efforts. The case in Concord may set precedents for how monitoring tools can be used in residential settings and the limits of government authority in housing oversight.
