Illinois's unique contribution to drone law is restricting government surveillance. The state also has hunting restrictions and local ordinance powers, but the Surveillance Act is the headline.
| Statute | What It Covers | Penalty |
|---|
| 725 ILCS 167/10 | Law enforcement cannot use drones to gather information (with exceptions) | Evidence inadmissible + agency loses drone authority 6-12 months |
| 725 ILCS 167/15 | Exceptions: warrant, imminent harm, missing person, crime scene, disaster | N/A (these are permitted uses) |
| 725 ILCS 167/20 | Data retention: agencies must destroy drone data within 30 days | Evidence inadmissible on violation |
| 520 ILCS 5/2.37 | Using drones to hunt, harass, or locate wildlife | Class B misdemeanor |
| 720 ILCS 5/48-3 | Interfering with hunters or fishermen using a drone | Class A misdemeanor |
| 720 ILCS 5/26-2 | Using drone over or surrounding occupied residence for recording or invading privacy | Criminal trespass charge |
The Freedom from Drone Surveillance Act
When Illinois passed 725 ILCS 167 in 2013, it was one of the first states to draw a hard line on government drone surveillance. The law starts with a blanket prohibition: a law enforcement agency may not use a drone to gather information, period. Then it lists narrow exceptions.
The exceptions require either a search warrant (limited to 45 days, renewable), reasonable suspicion of imminent harm (limited to 48 hours), a missing persons search (not combined with criminal investigation), crime scene or traffic crash photography, or disaster response. Even when agencies use drones under these exceptions, they must destroy all collected data within 30 days.
The enforcement mechanism has teeth. If a court finds by a preponderance of evidence that an agency violated the data collection limits, the information is presumed inadmissible. After an adverse judgment showing a pattern of violations, the agency loses its drone authority for 6 months on the first offense and up to one year on the second. Multiple Chicago-area law enforcement agencies have been found in violation of the Act's disclosure requirements.
Warning: The Surveillance Act restricts government drone use, not private citizens. There is no Illinois law preventing your neighbor from flying a drone over your property. Private drone surveillance falls under general eavesdropping and harassment laws, which have a higher bar for prosecution.
The October 2025 Chicago TFR
In October 2025, the FAA imposed unprecedented drone restrictions over most of Chicago. The Department of Homeland Security requested a 12-day ban covering a 15-nautical-mile radius from downtown, effectively grounding civilian drones across the city and many suburbs. The restriction coincided with federal immigration enforcement operations and was issued under the authority of federal airspace control, not Illinois state law. The incident showed that even in a state without aggressive private-drone regulation, federal authorities can shut down civilian operations overnight.
Chicago's Unique Legal Position
Illinois state preemption (620 ILCS 5/42.1) bars all local governments from passing drone ordinances, with one exception: municipalities with more than 1,000,000 inhabitants. Only Chicago qualifies. This means Chicago can and does pass its own drone rules, including bans on flying within 5 miles of O'Hare or Midway without FAA authorization, and prohibitions on flying over schools, hospitals, stadiums, police stations, and places of worship. No other Illinois city has this power.
Chicago Police Drone Program
Newly released Chicago Police Department data shows the department used drones hundreds of times between April 2024 and March 2025 for first response, search warrants, surveillance of large public gatherings, and other operations. Less than half of Illinois's 955 law enforcement agencies responded to a 2024 survey about drone use, and only 147 confirmed they had drones. The gap between the Surveillance Act's requirements and actual compliance is a live issue.
Stadium Drone Incident (2024)
In 2024, a 34-year-old man flew a drone into restricted airspace during a Big Ten football game at the University of Illinois Memorial Stadium in Champaign. The drone hovered within 10 feet of a SWAT officer in an overwatch position, capturing images of security tactics. University police used SkySafe drone detection technology to track the operator to a fourth-floor balcony half a mile from the stadium within minutes. The operator was arrested and charged with reckless conduct. Historical data from detection systems showed a pattern of prior unauthorized flights.
Note: Two bills are pending in the Illinois legislature as of March 2026. SB2364 (Unmanned Aerial Systems Security Act) would create a three-tier classification for government drones based on data collection capabilities and ban drones from "countries of concern" (targeting DJI). HB4332 would require registered sex offenders to register drone ownership with Illinois State Police. Neither has been enacted.
