This is a high-stakes question worth addressing from the current statutory text rather than shorthand. Colorado uses different rules for firearms and other deadly weapons on school property, and separate exceptions apply to some vehicle situations.

The general prohibition, which applies to everyone

C.R.S. 18-12-105.5 is not limited to concealed-handgun permit (CHP) holders. Subject to its stated exceptions, it prohibits knowingly carrying a firearm, openly or concealed, on the real estate and improvements of a licensed child-care center; public or private elementary, middle, junior high, high, or vocational school; or public or private college, university, or seminary. A related subsection addresses other deadly weapons carried knowingly, unlawfully, and without legal authority.

The current penalty structure distinguishes the two: a firearm violation under subsection (1)(a.5) is a class 1 misdemeanor, while a violation involving a deadly weapon other than a firearm under subsection (1)(a) is a class 6 felony. Older summaries may describe a firearm violation as a class 5 felony, but the statute was amended in 2024.

Where a concealed handgun permit fits in — and where it doesn't

Separately, C.R.S. 18-12-214(3) addresses specifically what a CHP does and doesn't authorize on K-12 school property (elementary, middle, junior high, and high schools). The general rule: a CHP does not authorize carrying a concealed handgun onto the real property of a public elementary, middle, junior high, or high school, or into any building on that property.

There are three carved-out exceptions to that:

The vehicle exception. A permittee may have a handgun on the real property of a public school as long as the handgun remains in the permittee's vehicle. If the permittee leaves the vehicle unattended, the current statute requires storage that complies with C.R.S. 18-12-114.5, Colorado's vehicle-storage rule. This is the exception most people are asking about—it can cover an ordinary drop-off or pickup with the handgun remaining in the vehicle, but unattended storage must satisfy the separate secure-storage requirements.

School security officers. A permittee employed or retained by contract with a school district or charter school as a school security officer may carry a concealed handgun on school property and in school buildings while on duty.

Undeveloped school-district land used for hunting or shooting sports. A permittee may carry a concealed handgun on undeveloped real property owned by a school district that's actually used for hunting or shooting sports — a narrow carve-out for rural districts with land used that way.

Outside those situations, a CHP does not itself authorize carrying on K-12 school property or in its buildings; C.R.S. 18-12-105.5 and its exceptions remain central to the analysis.

A wrinkle worth flagging rather than glossing over

18-12-105.5 has its own separate list of exceptions, and one of them is worth being careful about: subsection (3)(a) allows an unloaded weapon to remain inside a vehicle on the real property of a public or private college, university, or seminary — but that specific exception's text doesn't extend to K-12 schools (elementary, middle, junior high, or high). Separately, subsection (3)(c) exempts a person "in a private automobile or other private means of conveyance" carrying a weapon "for lawful protection... while traveling," without limiting that exception to college property specifically. Whether that general private-vehicle language independently covers a driver's car on K-12 property — separate from, and perhaps more broadly than, the CHP-specific vehicle exception in 18-12-214(3) — isn't something we've found settled anywhere in Colorado case law or attorney general guidance. If your situation isn't the clean case of "I have a CHP, and my locked handgun never leaves my locked vehicle," this is exactly the kind of edge case worth a direct answer from an attorney rather than our best reading of two statutes that weren't obviously written to fit together.

College and university property is handled differently

The current statute generally prohibits carrying a firearm on public or private college, university, or seminary property, subject to its listed exceptions. Those exceptions include an unloaded weapon remaining in a vehicle and a permit holder carrying a concealed handgun in a parking area. Colorado's 2012 Regents of the University of Colorado v. Students for Concealed Carry decision is important history, but legislation enacted in 2024 changed the statutory framework. Anyone relying on an older campus-carry summary should compare it with the current version of C.R.S. 18-12-105.5 and 18-12-214.

Bottom line

For K-12 schools specifically, a CHP does not generally authorize carrying inside school buildings or on school grounds. The permit statute provides limited exceptions for a handgun that remains in the permittee's vehicle, qualifying school security officers on duty, and hunting or shooting-sports use of undeveloped school-district land. The unattended-vehicle exception now points to Colorado's separate secure-storage rule. Because violations can carry serious criminal consequences—including a felony for covered deadly weapons other than firearms—edge cases should be addressed with a qualified Colorado attorney rather than assumptions or shorthand summaries.
