Colorado

State law generally allows open carry without a permit, but C.R.S. §29-11.7-104 (part of the state's shift to only partial preemption) lets local governments prohibit open carry in specific buildings/areas if posted, and Denver's own municipal code (D.R.M.C. §38-117(b)) bans open carry citywide regardless of a concealed permit. Whether open carry is legal genuinely depends on the specific municipality.

Colorado has no statute restricting CHP holders in churches; carry is allowed unless the specific place of worship posts signage prohibiting firearms, per ordinary private-property rules (C.R.S. §18-12-214 preserves private property owners' rights).

No Colorado statute restricts carry by location in bars or restaurants. C.R.S. § 18-12-106(1)(d) only prohibits possessing a firearm while under the influence of alcohol or a controlled substance (a class 1 misdemeanor).

Colorado's concealed handgun permit is generally valid statewide, but SB24-131 (2024) added an expanded 'sensitive spaces' list (government buildings, polling places, public college/university campuses, etc.) layered on top of older location limits like school grounds (C.R.S. § 18-12-105.5). I could not confirm from the primary bill/codified text whether state parks, public waterways, or marinas are captured, so I can't rule out a location-based restriction touching popular Colorado boating/reservoir areas.

C.R.S. §18-12-105.3 (added by SB24-131, effective 7/1/2024) makes it unlawful to knowingly carry a firearm in a government building, and §18-12-214(d) confirms a concealed handgun permit does not authorize carrying in violation of §18-12-105.3. This is a broad government-building ban, not just courts — covers a DMV or city hall as well as a courthouse. The only carve-out is permit holders may keep the firearm in an adjacent parking area.

Colorado allowed campus carry from 2012 (Regents of Univ. of Colo. v. Students for Concealed Carry) until SB24-131 ("sensitive spaces" law), effective July 1, 2024, which bans open and concealed firearms in buildings of public AND private colleges/universities; permit holders retain only a narrow exception to carry in campus parking areas.

Colorado has no statewide business-signage mandate; carry is allowed in essentially all private locations except a short statutory list (federal property, K-12 schools, courthouses). A posted business may exclude a carrier under general trespass law, but there is no opt-in requirement.

Checked Colorado's weapons statutes directly (C.R.S. 18-12-105.5, the sensitive-places-type provision) and found no rule requiring a private-property owner's advance consent. No such Colorado statute is known to exist; default governed by general first/second-degree criminal trespass law (C.R.S. 18-4-502/503), which requires actual notice. Moderate rather than high confidence since I could not locate a Colorado-specific firearm/private-property provision either way.

No Colorado statute naming airports was found. Colorado's concealed-handgun-permit law has a short list of restricted places (mainly public buildings with security screening at the entrance, K-12 schools) that usacarry.com's summary does not extend to airports, and Colorado has statewide firearms preemption (C.R.S. § 29-11.7-103) with only narrow local exceptions. However, I could not confirm how that preemption interacts with a home-rule airport authority, and I was blocked (403) from reading Denver International Airport's own posted rules or Colorado's preemption-exceptions text directly, so I can't rule out an airport-specific local restriction, particularly at Denver-owned DIA.

Colorado's concealed-carry statute specifically provides that a handgun is NOT considered 'concealed' if it is possessed by someone in a private automobile who is carrying it for a legal use (C.R.S. §18-12-105(2)) — so no permit is required specifically for vehicle carry, even though Colorado otherwise requires a permit to carry concealed on one's person outside a vehicle. C.R.S. §18-12-105.6 also bars localities from restricting travel with a weapon in a private automobile. Loaded long guns (rifles/shotguns) in a vehicle are separately restricted (chamber must be unloaded).

No Colorado statute prohibits firearms in hospitals; individual facilities may set their own posted policy.

Colorado is shall-issue. SB24-131's new 'sensitive spaces' list (government buildings, schools/childcare, polling places) does not mention rest areas or general vehicle carry. Verified against the official legislative bill summary.

No Colorado statute found requiring disclosure to law enforcement of concealed carry, proactively or if asked, in a comprehensive review of CO's carry-permit law.

C.R.S. 18-12-203(1)(a): permit requires being "a legal resident of the state of Colorado," but the statute explicitly deems a member of the armed forces stationed at a military installation in Colorado (and, per the statute, their spouse) to be a resident for this purpose — the only route for a true out-of-state domiciliary to get a Colorado permit.

Colo. Rev. Stat. §18-12-105.5(1)(a.5) bans firearms in/on K-12 property; permit holders may only carry there as an on-duty contracted security officer, with the handgun locked in a vehicle compartment, or on undeveloped school-district land used for hunting/shooting sports (§18-12-214(3)) — no general campus carry even with a valid permit. Districts may adopt further restrictions.

No Colorado-specific firearm-signage criminal statute is known to me, and I was unable to fetch the text of the general trespass statutes (C.R.S. §§ 18-4-502/504) in this session to confirm whether posted signage alone (versus a personal request to leave) satisfies the notice element for a business context.

Colorado repealed most of its firearm preemption in 2021 (SB21-256). C.R.S. § 29-11.7-103 now expressly allows a local government to enact an ordinance MORE restrictive than state law on possession/sale/transfer of firearms (just not less restrictive), and § 29-11.7-104 lets localities ban open carry in buildings/areas. So cities/counties can and do impose additional carry-related restrictions beyond state law.

Colo. Rev. Stat. § 1-13-724 makes it unlawful to carry a firearm within any polling location or within 100 feet of a ballot drop box. Exceptions are limited to carrying on one's own private property within the buffer, uniformed/contract security, and on-duty peace officers — no CCW-permit carve-out.

15-round limit (C.R.S. §§ 18-12-301, 18-12-302), with a grandfather clause for magazines continuously possessed since on/before July 1, 2013 (state bears burden to disprove). 2025 SB 3 additionally restricts 'rapid-fire devices,' effective Aug. 2026. Currently enforced; no injunction found.

Extreme Risk Protection Order, C.R.S. § 13-14.5-101 et seq. (2019). Petitioners: family/household members, a defined class of 'community members,' law enforcement officers/agencies, and licensed health-care/mental-health professionals.

Colorado's 'dangerous weapon' statute (C.R.S. §18-12-102) defines silencers, machine guns, short shotguns, and short rifles as felony contraband on its face, without carving federal compliance out of the definition. A valid federal permit/license (NFA tax stamp/registration) only supports an affirmative defense that must be raised if charged — legal commentary notes Colorado 'does not clearly legalize suppressors the way many other states do.' In practice NFA-compliant owners are not prosecuted, but the legal footing is a defense rather than a true exemption, applying to suppressors, SBR/SBS, and machine guns alike.

No SYG statute; case law (Idrogo v. People, 818 P.2d 752 (Colo. 1991)) establishes no duty to retreat when lawfully present.

Colo. Rev. Stat. § 18-12-112 requires nearly all private firearm transfers to be run through a licensed dealer for a CBI background check; exceptions for immediate family gifts, antiques, and brief transfers for hunting/sporting/self-defense (under 72 hours).
