Why this matters
HB 5323 rounds out Michigan’s late-2025 UAS package by authorizing physical/technical geofencing at critical infrastructure and state buildings, moving beyond purely criminal (HB 5319/5320) and database-based (HB 5321/5322) approaches. Situating this authority in the Management and Budget Act signals it will be administered through state facilities management, affecting how state-owned infrastructure is protected from drone incursions.
