Where You Can Carry in Idaho: Permitted Places, Prohibited Zones, and the Rules in Between

Idaho operates on permitless (constitutional) carry. Under Idaho Code § 18-3302(3) and (4), any U.S. citizen or active-duty military member aged 18 or older who is not otherwise disqualified can carry a concealed handgun anywhere in the state without a license — inside city limits or outside them. That restriction limiting permitless carry to areas outside city limits was repealed when the legislature broadened the law in 2020.

Open carry requires nothing at all. Idaho Code § 18-3302(4)(a) and (b) explicitly exclude "any deadly weapon located in plain view" and "any lawfully possessed shotgun or rifle" from the concealed weapons statute entirely. If it's visible, the statute doesn't touch it.

Vehicle carry follows the same logic. Loaded or unloaded, handgun or long gun, openly or concealed, in the cab or in the trunk — all legal without a permit, provided you meet the standard age and eligibility requirements. No requirement to lock the firearm in a case or store ammunition separately while driving in Idaho.

That's the baseline. What follows are the places where that baseline gets cut back.

Courthouses, jails, and juvenile detention facilities are off-limits for concealed carry. Per Idaho Code § 18-3302C, carrying a concealed weapon in a courthouse, juvenile detention facility, or jail is prohibited. Authorized law enforcement and corrections personnel are the relevant exception.

K-12 schools carry a separate and more detailed prohibition. Idaho Code § 18-3302D makes it a crime to possess a firearm on the property of any private or public elementary or secondary school — buildings, grounds, stadiums, and other structures on school grounds when being used for a school-sponsored activity. The prohibition extends to school-provided transportation. Students attending or participating in any school-sponsored activity, program, or event are subject to the same prohibition regardless of where the event is held.

The exceptions written into the statute are narrow:

• Any adult non-student in lawful possession of a firearm that is secured and locked in their vehicle in an unobtrusive, nonthreatening manner
• A person lawfully possessing a firearm in a private vehicle while delivering minor children, students, or school employees to and from school or a school activity
• Any person or employee of the school or school district who is authorized to carry by the board of trustees of the school district or the governing board

On the school board authorization exception: the Idaho Second Amendment Alliance has been pushing for legislation — including House Bill 415, which failed to pass — that would have explicitly allowed school employees with enhanced concealed carry permits to carry on school grounds without requiring board authorization on a case-by-case basis. That bill did not advance, meaning school board permission remains the operative mechanism for staff carry as of 2026.

Federal property is governed by federal law, not Idaho law. 18 U.S.C. § 930 prohibits firearms in federal facilities — post offices, VA hospitals, military installations, federal courthouses, federal buildings. Idaho's permissive carry laws don't reach these locations. TSA security checkpoints at airports are federal zones. The public areas of commercial airports (before the security checkpoint) are not covered by the federal facility prohibition, but check the specific airport's posted rules and any applicable state or local ordinance.

The Gun-Free School Zones Act (GFSZA), 18 U.S.C. § 922(q), extends a federal prohibition to within 1,000 feet of a K-12 school — not just the school grounds. Idaho Enhanced Concealed Weapons License holders are exempt from the GFSZA under the statute's licensed-carrier exception. Standard permitless carriers are not covered by that federal exemption, which means a loaded handgun in your car within 1,000 feet of a school creates federal legal exposure if you're carrying without an Idaho Enhanced License.

This is where your license type matters most in terms of where you can go.

Public colleges and universities in Idaho are authorized under Idaho Code § 18-3309 to prescribe rules and regulations relating to firearms on their property — but that authority specifically does not extend to regulating or prohibiting carry by Enhanced Concealed Weapons License holders or holders of a qualified retired law enforcement officer license.

In plain terms: if you have a standard license or are carrying under permitless carry, the university can restrict you. If you have an Enhanced License, the university cannot ban you from campus — with two specific exceptions.

Even Enhanced License holders cannot carry:

• Inside any student dormitory or residence hall
• Inside any building of a "public entertainment facility" owned by the college or university — defined as theaters, auditoriums, sports arenas, and similar facilities with a seating capacity of at least 1,000 — when proper signage is conspicuously posted at each public entrance notifying attendees of the restriction during a game or event

The dormitory and entertainment facility restrictions are statutory, not just university policy. They apply to Enhanced License holders regardless of what the university posts or doesn't post — except that the entertainment facility restriction is conditional on proper signage being in place.

According to Giffords Law Center (citing Idaho Code §§ 18-3302C and 18-3302D(4)(f)), the entertainment facility exception does not apply to a person who possesses a firearm in a private vehicle while delivering students, employees, or other persons to and from a university, college, or public entertainment facility.

Community colleges and private institutions fall outside the specific statutory mandate and set their own policies. Check with the institution directly.

Idaho law limits the ability of government-owned property to restrict concealed carry. According to Giffords Law Center (citing Idaho Code), any restriction on the carrying of concealed weapons at government-owned property may only be invoked when the use of such property is for specified purposes — not as a blanket, permanent prohibition.

Private events by invitation only, commercial events that charge admission, or other events with restricted access are the categories where a government-owned property can enforce a carry restriction under Idaho Code § 18-3302(25). A government-owned facility that is normally and habitually open to the public and is leased or loaned to a private entity does not get to inherit private property restriction authority unless the event meets one of those specific criteria.

Idaho Code § 18-3302(25) preserves the right of private property owners, private employers, and private business entities to regulate the carrying of weapons on their property. A clearly posted notice constitutes legal notice.

Here's the practical legal reality: carrying past a "no firearms" sign in Idaho doesn't violate the weapons statutes. It triggers trespass law. When asked to leave, you must leave — at that point you're a trespasser if you refuse, not a gun law violator. Compliance and departure is the correct move.

Idaho has no statutes prohibiting firearms in the following places, per Giffords Law Center:

• Hospitals
• Sports arenas (other than those related to an elementary or secondary school or certain university-owned facilities)
• Gambling facilities
• Polling places
• Establishments that serve alcohol

Administrative regulations may apply in some of these locations even absent a statute. Specifically, Idaho Admin. Code r. 16.03.09.714 requires any agency that enters into a Medicaid provider agreement with the state for the provision of mental health clinic services to prohibit firearms in the clinic facility. Idaho Admin. Code r. 21.01.01.201 covers state veterans' homes. Children's residential care facilities and children's therapeutic outdoor programs also prohibit firearms under state administrative regulations, per Giffords Law Center.

Hotels occupy an interesting niche. Per Idaho Code Ann. § 39-1805 and § 39-1809, a hotelkeeper has the right to evict a person who seeks to bring a firearm into the hotel. The hotel is not required to provide accommodations to any such person. This isn't a criminal prohibition — it's a civil property right — but it means hotels can and do set their own policies.

If the list above makes you want to actually get a license, the Enhanced License is the one to get. Per Idaho Code § 18-3302K, Enhanced License holders get two significant location-access benefits that permitless carriers and standard license holders don't:

• Campus carry access at public colleges and universities (with the dormitory and posted entertainment venue exceptions noted above)
• Federal GFSZA exemption for the area surrounding K-12 schools

The training requirement is an 8-hour in-person course covering Idaho law and live-fire qualification. The application fee is $20 for residents. The reciprocity benefit is substantial — roughly 38 states recognize the Enhanced License versus around 15 for the standard license. If you travel with any regularity, the eight hours is worth it.

Carrying while under the influence is a criminal offense under Idaho Code § 18-3302B regardless of where you are or what license you hold. A campus carry violation carries an automatic three-year license revocation on top of any other penalties.

With one exception, cities and counties in Idaho cannot enact firearms laws more restrictive than state law. Idaho Code § 18-3302J preempts all local ordinances that "regulate in any manner the sale, acquisition, transfer, ownership, possession, transportation, carrying or storage of firearms or any element relating to firearms and components thereof, including ammunition."

The exception is discharge. Municipalities can regulate the discharge of firearms within their limits — a city can prohibit firing a gun inside town. That's regulating discharge, not possession or carry, and it falls outside the preemption statute. Counties have similar authority over discharge, with carve-outs for lawful self-defense, hunting, discharge on a landowner's property when it won't endanger others, sport shooting ranges, and target shooting on public land.

Older municipal ordinances that conflict with state law remain on the books in some jurisdictions as unenforceable relics. State law wins any conflict.

House Bill 621, a concealed carry clarification bill, was printed and introduced in the House State Affairs Committee as of early 2026, per NRA-ILA. The specifics of what it clarifies were not available from the sources reviewed. The 2026 legislative session opened January 12, 2026.

Senate Bill 1349 was also introduced in the 2026 session. Per the available snippet from BillTrack50, the bill explicitly states that it does not authorize prohibited persons to possess machine guns and does not affect general criminal laws. Full text was not available from the sources reviewed — track it at legislature.idaho.gov before drawing conclusions.

Background check fees increased effective January 1, 2026, per Idaho News 6 — fingerprint-based criminal background checks and initial concealed carry license fees were adjusted. The concealed carry license fee under the new schedule is $20.

The school carry debate is ongoing. ISAA has stated it will continue pushing legislation to eliminate gun-free zone requirements in public schools and permit trained staff to carry. No such legislation had passed as of the sources reviewed.

The bottom line: Idaho gives you enormous latitude on carry — but courthouses, K-12 school grounds, federal facilities, and campus dormitories are hard stops, and your license type determines what you can access at public universities.
