Idaho

Idaho Code §18-3302 licenses only concealed carry; open carry of a handgun has never required a license for anyone 18+ (residents since 2016, nonresidents since 2020) who is not a prohibited possessor.

No Idaho statute addresses churches specifically (Idaho Code §§18-3302, 18-3302C, 18-3302D govern courthouses/jails/schools, not places of worship). Ordinary private-property discretion applies.

No Idaho statute restricts carry by location in bars/restaurants. Idaho Code § 18-3302B only makes it a misdemeanor to carry a concealed weapon while intoxicated or under the influence.

Idaho allows permitless carry statewide for qualifying adults 18+ (Idaho AG: 'you may carry a concealed weapon on your person without a concealed weapons license'). No boat/vessel/waterway restriction was found in Idaho's carry law.

Idaho Code §18-3302C bars carrying a concealed weapon into 'a courthouse; juvenile detention facility or jail,' with exceptions for peace officers, security personnel, and anyone authorized by the entity controlling the building. This section does not reach general government buildings like a DMV office or city hall, which are not restricted by state law. A 2026 bill (H621) to loosen the courthouse rule to allow carry outside courtrooms/jail areas was still pending as of this research and is not yet law.

Idaho Code § 18-3309 lets only ENHANCED concealed-carry-license holders (or qualified retired LEOs) carry on PUBLIC college/university property, excluding dormitories and sporting/entertainment venues seating 1,000+; standard-license-only holders are not covered, and § 18-3302C bars schools from further restricting enhanced holders. Private institutions aren't covered by the statute and set their own policy.

Idaho is a highly permissive constitutional-carry state with no statewide signage mandate; a property owner may ask a carrier to leave (Idaho Code § 18-7008, trespass), but absent any request/notice carry in an ordinary business is lawful.

No ID statute requires advance owner consent; general criminal trespass law (Idaho Code 18-7008) requires notice before presence becomes unlawful (opt-out default). Constitutional-carry state.

No Idaho statute or secondary source I found lists airports among Idaho's restricted locations (usacarry.com's list: courthouses, jails/prisons/correctional facilities, schools). Idaho is permitless carry with a specific, strongly worded firearms-preemption statute (Idaho Code § 18-3302J), which would tend to prevent a local airport authority from imposing its own ban, but I did not independently verify that statute's text or its application to Boise Airport, so this remains unconfirmed rather than a settled yes.

Idaho Code §18-3302(4)(c) exempts 'any deadly weapon concealed in a motor vehicle' from the concealed-weapons-license requirement entirely — this exemption is separate from (and broader than) Idaho's age-based permitless-carry-on-the-person rules (21+ statewide, 18-20 only outside city limits), and applies regardless of whether the vehicle is inside or outside city limits.

No statute restricts general hospitals. But Idaho Admin. Code r.16.03.09.714 requires any mental-health CLINIC that has a Medicaid provider agreement with the state to prohibit firearms on its premises as a condition of that agreement — so a small Medicaid-participating behavioral-health clinic can be off-limits while a general hospital ER is not.

Idaho is constitutional-carry. Idaho Code §18-3302C's prohibited-place list is narrow (courthouses, jails/detention, schools) with no rest-area mention. Verified against the statute text directly.

No Idaho statute found imposing a duty to inform law enforcement of concealed carry, proactively or if asked.

Idaho Code § 18-3302K(4)(b): applicant must have been an Idaho resident 6+ months "OR holds a current license or permit to carry concealed weapons issued by his state of residence." So a true non-resident can get Idaho's enhanced license only if they already hold a valid CCW permit/license from their own home state. Application is filed through any county sheriff's office.

Idaho Code §§18-3302D(1)(a)-(b), 18-3302C ban firearm possession on K-12 property; unlike Idaho's law for colleges/universities (which does carve out enhanced permit holders), there is no comparable concealed-carry exception for K-12 campuses — only board-approved programs, secured vehicle storage by non-enrolled adults, and authorized personnel are excepted.

No Idaho-specific firearm-signage criminal statute is known to me. Idaho's general trespass law (Idaho Code § 18-7008) may treat posted notice as sufficient for entry-type trespass, but I could not fetch its text to confirm application to a firearms-specific sign at a retail business in this session.

Idaho Code § 18-3302J: counties/cities/political subdivisions may not regulate sale, possession, transport, or carrying of firearms. Cities/counties may only regulate discharge, with self-defense/hunting/range exceptions preserved.

No Idaho statute found prohibiting firearms at polling places. Idaho has constitutional (permitless) carry for adults 18+; official prohibited-carry guidance (courthouses, federal buildings, private property) does not mention polls. Based on MAP research plus light corroboration.

No state-level magazine capacity restriction found.

No extreme risk protection order or red flag statute found in Idaho.

Idaho imposes no additional state-level restriction on suppressors, SBR/SBS, or machine guns beyond the federal NFA process. No Idaho Code provision (Title 18, Chapter 33) specifically restricts these categories; secondary NFA-dealer sources uniformly describe Idaho as having zero state add-on requirements, and suppressor use while hunting is affirmatively permitted.

Stand Your Ground by statute: Idaho Code § 19-202A(3) (also § 18-4009, justifiable homicide) — no duty to retreat.

No Idaho statute requires background checks on private firearm transfers. Confirmed via absence from Giffords' UBC list.

No provision in Idaho Code Title 18, Chapter 33 restricts suppressors; secondary NFA-dealer sources uniformly describe Idaho as having zero state add-on requirements, and suppressor use while hunting is affirmatively permitted.

No Idaho statute imposes an added state restriction on a lawfully-transferable machine gun beyond the federal NFA process.

No Idaho statute imposes an added state restriction on a federally-registered SBR.

No Idaho statute imposes an added state restriction on a federally-registered SBS.

Idaho Code §18-3319 only criminalizes possessing a bomb or destructive device for an 'unlawful purpose' or by someone already a prohibited possessor -- simple possession by an otherwise-lawful, federally-registered owner isn't itself a crime -- and no Idaho statute separately names AOWs.
