Beginning July 1, 2026, flying a drone over an Idaho state prison will be a criminal offense regardless of whether the pilot meant to. Idaho House Bill 522, signed into law by Governor Brad Little on March 31, 2026, creates a new section of state code — Idaho Code 20-251 — that carves out "restricted airspace" above every Idaho Department of Correction facility and bars unmanned aircraft from entering it. The measure, filed as Session Law Chapter 233, creates a prison-specific no-fly zone with its own detection and mitigation authority built directly into state statute, rather than leaning solely on federal Temporary Flight Restrictions or general trespass law.

The bill was sponsored by the House Judiciary, Rules and Administration Committee and was driven by a problem corrections officials across the country have struggled to contain: drones ferrying contraband over prison walls.

What the Law Actually Does

Idaho Code 20-251 defines "restricted airspace" as the airspace from the surface up to 400 feet above ground level (AGL), bounded by the "defined perimeter" of a correctional facility. Flying a drone anywhere inside that airspace — intentionally or not — is a misdemeanor. Under the statute's text, a conviction carries a mandatory fine of no less than $2,000 and no more than $5,000, up to one year in jail, and mandatory forfeiture of the drone used in the offense.

Critically, the statute closes off the most common defense in unauthorized-overflight cases: not knowing you were above a prison. HB 522 explicitly states that "lack of knowledge that the prohibited act occurred within the restricted airspace of the correctional facility shall not be a defense." That provision shifts the burden onto operators to know where they're flying, effectively requiring drone pilots statewide to check facility locations before launching near any Department of Correction property.

The law also grants the Department of Correction and law enforcement agencies authority to take "reasonable and necessary mitigation measures" against a drone reasonably suspected of operating in a "nefarious manner" — defined in the statute as an illegal, dangerous, or harmful purpose, such as spying, smuggling contraband, facilitating criminal activity, or posing a direct threat to a facility's safety or security — within restricted airspace. Idaho Code 20-251 spells out what those measures can include: detection, tracking, and identification methods, plus interception or disabling of the drone through "legal and safe methods, including but not limited to jamming, hacking, or physical capture." The department and law enforcement are shielded from liability for damage to a drone caused by mitigation taken under the law, and the Department of Correction is required to post "Drone No Fly Zone" signage on roads near its facilities.

Why Now: The Contraband Problem

HB 522 didn't emerge in a vacuum. As detailed in a Gem State Chronicle piece authored by Idaho Attorney General Raúl Labrador, Idaho prisons — like correctional facilities nationwide — have faced a mounting wave of drone-delivered contraband: drugs, cellphones, and weapons smuggled to inmates, fueling addiction, violence, overdoses, and even fraud schemes and witness intimidation run from behind bars. Labrador's piece frames the state-level legislation as necessary but incomplete, arguing Idaho also needs expanded federal authority — specifically, permission for state and local law enforcement to detect, track, and disable unauthorized drones over correctional facilities — a signal that Idaho's top law enforcement officer sees HB 522 as one layer of a response that ultimately requires federal cooperation on counter-drone authority, given that airspace regulation and electronic countermeasures are otherwise reserved largely to federal agencies.

That tension — states wanting to physically disable drones over sensitive facilities while federal law reserves broad authority over aircraft operations and electronic countermeasures — has shaped counter-drone policy fights nationally for years. Idaho's answer was to legislate the no-fly zone and detection/mitigation authority at the state level now, while continuing to push Washington for the broader authority federal agencies currently hold outright. Labrador has also joined roughly twenty other state attorneys general in a letter to the National Security Council pressing for that expanded authority.

How It Compares to Existing Rules

Federal law already restricts drone flights over certain prisons through FAA Temporary Flight Restrictions and, in some cases, permanent flight restrictions tied to national security or critical infrastructure designations. But those restrictions are not uniform across all correctional facilities, and enforcement typically falls to the FAA rather than state corrections staff or local police standing at the fence line.

HB 522 changes that dynamic within Idaho by writing the no-fly zone directly into state criminal code and by giving the Department of Correction itself — not just the FAA — a statutory basis to detect and respond to incursions in real time. That combination is what sets Idaho apart: a defined 400-foot AGL ceiling, a facility-perimeter boundary, a misdemeanor charge enforceable by state and local authorities, and an explicit grant of detection/mitigation power to the agency actually running the prison.

Questions the Law Raises

Does the 400-foot ceiling apply everywhere in Idaho, or just at prisons? Only at Department of Correction facilities. The restricted airspace is tied specifically to the perimeter of each facility; it is not a statewide altitude cap.

Can hobbyists get in trouble for accidentally overflying a prison en route somewhere else? Under the letter of the law, yes. Because ignorance of flying over a facility is explicitly not a defense, a pilot who strays into restricted airspace without realizing a prison is below them is still exposed to misdemeanor charges, a $2,000–$5,000 fine, up to a year in jail, and mandatory drone forfeiture.

What kind of "mitigation" is authorized? HB 522 authorizes detection, tracking, and identification methods, plus interception or disabling of a drone through jamming, hacking, or physical capture. Unlike the underlying no-fly misdemeanor, which applies regardless of intent, active mitigation may only be used when the Department of Correction or a law enforcement officer has reasonable suspicion the drone is operating in a "nefarious manner" — an illegal, dangerous, or harmful purpose such as spying, smuggling contraband, or threatening facility safety — within restricted airspace.

Is this just about contraband, or is it also a security/safety law? The wave of drone-delivered drugs, phones, and weapons documented in reporting on Idaho prisons was the immediate driver, but the statute's definition of "nefarious manner" — spying, smuggling, facilitating criminal activity, or posing a direct threat to public safety or facility security — mirrors the framework used for critical-infrastructure and security-sensitive site protections more broadly.

Why It Matters

Prison contraband drops are one of the clearest, most persistent real-world abuse cases for small drones, and corrections agencies across the country have lacked a clean legal tool to stop them beyond after-the-fact trespass or smuggling charges once contraband is recovered. Idaho's approach — a defined restricted-airspace zone, a strict-liability misdemeanor, and explicit detection/mitigation authority for the facility operator — gives prison officials a proactive legal basis to act while a drone is still in the air, not just after contraband lands in a yard.

It's also a bellwether. Counter-drone authority for state and local agencies has been a persistent gap in U.S. drone law, with much of the detection and mitigation power concentrated at the federal level. By writing detection and mitigation authority directly into a state corrections statute, Idaho is testing a model other states grappling with the same contraband problem — and the same federal-authority bottleneck flagged by Attorney General Labrador — are likely to watch closely. If HB 522 holds up and proves effective, similar prison-airspace bills could surface in other state legislatures in the coming years.
