Colorado Security Guard & Company License: Requirements & How to Verify (2026)

Hiring a security company in Colorado? Confirming its license is the single most important check you can make — it's what tells you the provider is lawful, insured, and accountable, and it shields you from the negligent-hiring liability that comes with putting an unvetted, uninsured operation on your property. This guide covers who regulates security in Colorado, what a company and its guards must hold, how armed work is permitted, and exactly how to verify a license yourself.

What makes Colorado different

Colorado has no statewide security-company license — and it nearly did. House Bill 25-1262 would have created a state Board of Private Security Services and required state licenses starting August 1, 2026, but it died: the House Finance Committee voted 13-0 to postpone it indefinitely on April 7, 2025 (a predecessor bill failed too). A number of vendor sites still present that August 2026 start date as enacted law — it isn't. So regulation remains municipal, and the schemes vary: Denver licenses guards and companies through its Department of Excise & Licenses and requires 16 hours of police-approved training (8 for Colorado Springs), with an armed endorsement adding a firearms course and, generally, a concealed-carry permit. Verify at the city that licenses the job site, and confirm insurance directly, since there is no state floor.

Who regulates security in Colorado

Colorado does not license security companies at the state level. Regulation runs through city and county governments — Colorado has no statewide security regulator, so a firm is authorized through a municipal license where required (there is no statewide company license) and there is no single statewide registry to check. Ask exactly which authorization the provider holds and where it's registered, and confirm it directly — in a state with no central lookup, a firm that can't answer that clearly is a red flag, and the provider's own vetting, training, and insurance carry more weight than any state floor.

What each security credential authorizes in Colorado

"Licensed" alone doesn't tell you what an officer is actually cleared to do — Colorado uses more than one credential, and they aren't interchangeable. Here's what each one authorizes:

Guards and training

In Colorado, a municipal guard license where required (for example, Denver's security-guard license); there is no statewide credential, and set by the city — Denver requires 16 hours of police-approved training, Colorado Springs 8 hours; there is no statewide standard. With no statewide standard to fall back on, the provider's own screening and training program is what separates a professional firm from a marginal one — ask directly how officers are vetted and trained, and what documentation the company keeps.

Armed guards and firearms in Colorado

Arming a guard in Colorado takes more than the base credential: an armed officer needs a municipal armed endorsement (in Denver, an added firearms course), generally with a concealed-carry permit, with a minimum age of 21. Armed coverage also raises your exposure — a firearms incident can reach the client through vicarious-liability and negligent-hiring theories, and standard general-liability policies often exclude firearms — so confirm the specific armed credential (not just the base registration) and the firm's firearms coverage, and reserve armed posts for a documented threat. Our armed vs. unarmed guide covers the decision in depth, and you can compare armed security services directly.

In Colorado, armed authority for guards has been granted at the municipal level rather than by any statewide permit. Denver, the leading example, requires a guard to first hold the base Denver Security Guard License and then add a firearm endorsement from Excise & Licenses before carrying on duty. The endorsement requires an added 5 hours of classroom instruction plus 3 hours of live-fire range time under a POST- or NRA-certified instructor, an 80% qualification score, and yearly retraining and requalification to keep armed status. An endorsed guard must be at least 21 and may carry no more than two firearms while performing security services. The endorsement authorizes open carry in uniform; a plainclothes armed assignment additionally requires a plainclothes endorsement and a valid Colorado concealed-handgun permit issued by a county sheriff, since the municipal endorsement is not itself a civilian CCW. Note: under HB25-1262, effective August 1, 2026, a new state Board of Private Security Services assumes licensing statewide and only commercial security officers holding a board-issued weapon endorsement may carry.

What security guards can and can't do in Colorado

A Colorado security guard's arrest power comes from the state's private-person arrest statute, C.R.S. § 16-3-201, which authorizes a non-peace-officer to arrest only when any crime has been or is being committed in that person's presence — it contains no separate "felony reasonably believed committed" power. Any physical force used to effect such an arrest is limited to what is reasonable and appropriate under C.R.S. § 18-1-707, and the arrest must be lawfully authorized before force may be applied (People v. Joyce). Retailers get a narrower tool in the merchant's-privilege statute, C.R.S. § 18-4-407, which lets a merchant or employee detain and question — not arrest — a suspected shoplifter in a reasonable manner, in good faith and on probable cause, shielding the store from false-arrest and slander claims but never authorizing punishment or prolonged detention. Colorado has no statewide "special police officer" commission conferring sworn arrest powers on private premises, so a guard's authority stays limited to these civilian doctrines. On reach, § 18-4-407 protects only “the merchant or any employee thereof or any peace officer” — the statute never says “agent” or “contractor.” A contract guard's officer is an employee of the guard company, not of the store, so a contracted guard falls outside the merchant's-privilege words and cannot claim its shield, which runs civilly or criminally only to the merchant, the merchant's own employee, and peace officers; a Colorado contract officer is thrown back on the narrower private-person arrest power of C.R.S. § 16-3-201.

Local requirements in Colorado

Some Colorado cities layer their own rules on top of the baseline requirements. If your site is in one of these, confirm the local layer too:

• Denver: Excise & Licenses requires the guard license before starting work (a signed Letter of Hire from a licensed private security employer is mandatory) and limits armed, endorsed guards to carrying no more than two firearms while performing security services; the armed endorsement requires 5 hrs classroom + 3 hrs live-fire, an 80% score, and yearly requalification.

How to verify a security license in Colorado

Verification takes only a few minutes and is the check that protects you:

1. Get the authorization details in writing from the provider — don't accept a logo or a verbal claim.
2. Open the official source — your city's licensing office (for example, Denver Excise & Licenses), not a third-party directory.
3. Confirm the record is active, unexpired, matches the exact legal business name and address, and shows no disciplinary action.
4. Verify the officers — Colorado sets no individual guard credential to check, so ask for the firm's documented vetting and training records instead, plus the armed credential for any armed post.
5. Confirm insurance and subcontracting — request a current certificate of insurance and confirm it meets or exceeds set by the municipality (there is no statewide requirement), plus workers' compensation, and ask in writing whether any of your posts will be subcontracted to another firm.

Re-verify at renewal. Renewal in Colorado: on the schedule the licensing city sets (Denver renews annually). A credential can also be suspended between renewals, so a check isn't one-and-done — re-check at renewal time and before signing a new contract.
