UAS Geofencing at Critical Infrastructure

Current understanding

Michigan HB 5323 would amend the Management and Budget Act (1984 PA 431) by adding sec. 219a to authorize the installation of geofencing around critical infrastructure or state buildings to restrict unmanned aircraft systems (drones) from entering those airspaces. The bill is at the introduced stage and complements parallel UAS bills that criminalize drone trespass over key facilities (HB 5319) and establish a database of restricted zones (tie-barred to HB 5321).

• 2025-12-02 — Aeronautics: unmanned aircraft systems; destruction of drones flying in violation of critical infrastructure guidelines; allow. Amends 2016 PA 436 (MCL 259.301 - 259.331) by adding sec. 8a.: 2025-12-02 — HB 5325 (adding sec. 8a to 2016 PA 436) would allow destruction of UAS violating critical infrastructure guidelines, an active kinetic enforcement alternative to the passive geofencing barrier authorized by HB 5323. (novelty: 3)
• 2025-12-02 — 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.: cross-connection with uas-critical-infrastructure-trespass: Geofencing (HB 5323) provides the physical/technical means to enforce the drone-trespass prohibitions HB 5319 would add to sec. 45a for key facilities and critical infrastructure.
