Aeronautics: unmanned aircraft systems; installation of geofencing around critical infrastructure or buildings; allow. Amends 1984 PA 431 (MCL 18.1101 - 18.1594) by adding sec. 219a.

HB 5323 authorizes Michigan state agencies to install technology that detects or blocks unauthorized drones near state-owned buildings and critical infrastructure like power plants or water facilities. The bill allows for two key mechanisms: (1) devices to detect drones flying overhead, and (2) systems to prevent drones from entering restricted airspace. It also requires coordination with the state transportation department to include these locations in a statewide geofencing database. The law explicitly states it does not override federal drone regulations.
