- The Concord Housing and Redevelopment Authority (CHRA) installed roughly 300 Minut Monitor sensors inside tenant apartments starting in late 2024, spending about $46,060 on the hardware.
- The sensors generated what the ACLU's complaint tallies as several hundred million individual data readings on motion, sound and nearby device signals — including more than 140,000 motion readings logged from a single unit.
- A class-action suit filed September 2, 2026 argues the monitoring violates tenants' rights under the New Hampshire Constitution; CHRA says the sensors exist only to flag indoor smoking and pinpoint noise complaints.
A single sensor inside one Concord apartment logged upward of 140,000 motion readings across roughly seven months — and the tenant living there says he never agreed to be tracked that closely. That figure, surfaced through a public records request, now anchors a lawsuit challenging how New Hampshire's capital city monitors residents inside its federally subsidized housing.
