How Old Do You Have to Be to Get a Hotel Room in Colorado? (2026)

The short answer

No. There is no Colorado statute that sets a minimum age to rent or check into a hotel room. If you're 18, 19, or 20 and trying to book a room in Denver, Colorado Springs, or a mountain town like Vail or Aspen, the age requirement you run into is set by the hotel brand or the individual franchisee — not by Colorado law. This puts Colorado in line with the general pattern seen across most states: age-to-book is a business policy question, not a legal one.

What we actually checked in the Colorado statutes

Before writing this off as "just policy," we pulled the relevant Colorado Revised Statutes directly rather than relying on secondhand claims. Here's what's there:

• C.R.S. § 6-25-201 (Title 6, Consumer and Commercial Affairs) gets cited around the web as "the Colorado hotel age law" because it defines "minor" as a person under eighteen years of age. But read the actual text and it's a pure definitions section — it defines terms like innkeeper, lodging establishment, minor, and resort for use elsewhere in that part of the code. It does not say a minor can or cannot rent a room, and it sets no check-in age requirement at all. Citing it as a booking-age law is a misreading.
• C.R.S. Title 18, Article 14 (§§ 18-14-101 to 18-14-104) — "Hotel Facility Rates: Posting — Notice" — covers rate disclosure and posting requirements. It has nothing to do with age.
• No other Colorado statute — consumer protection, contract law, or innkeeper liability — imposes a specific minimum age for renting a room.
• No guidance from the Colorado Attorney General or the Department of Regulatory Agencies (DORA), and no municipal ordinance, sets a check-in age either.

Bottom line on the law: nothing found. One relevant side note — turning 18 in Colorado makes you a legal adult with full contract capacity, which is why 18 is the age brands generally use as their floor. But that's general contract law, not a hotel-specific statute.

So what actually determines the age at check-in?

Since there's no state law, the age you'll be held to comes down to whichever brand's sign is on the building — and sometimes the specific franchisee running that location. Nationally set brand policies apply the same way in Colorado as everywhere else:

What this looks like on the ground in Colorado

In practice, most major-chain properties across Denver, Colorado Springs, and the ski towns will let an 18-year-old check in with a valid government-issued ID and a credit or debit card in their own name. That covers the majority of bookings.

Where it gets inconsistent is at resort-area and nightlife-adjacent properties — think Vail, Aspen, Breckenridge, or hotels near Denver's downtown bar districts. A real, documented subset of these properties set a house policy requiring guests to be 21+, generally cited as a liability or insurance decision made at the property or franchisee level. That is a business decision, not anything required by Colorado law. It's also why some travel and booking sites maintain curated lists of hotel chains that reliably let 18-year-olds check in — the variation is real enough that it's worth checking before you book, not after you drive up.

How to avoid a denied check-in

Since the age floor isn't standardized by law, the practical move is to verify at the property level, not the brand level:

• Call the specific hotel before booking, especially for resort towns or properties near nightlife.
• Check the property's own policy page on the booking site — franchise-level exceptions are usually disclosed there.
• Bring a valid ID and a card in your own name — this is required almost everywhere regardless of age.
• Avoid booking last-minute at 21+ properties if you're 18-20 — a denied check-in at 10pm with no refund is the actual risk, not a legal violation.

Bottom line

• Confirmed state law: None found setting a minimum hotel check-in age in Colorado. § 6-25-201 only defines "minor" for unrelated statutory purposes — it is not an age-of-rental law, despite how it's sometimes cited.
• Brand/franchise policy commonly encountered in Colorado: 18 is standard at most major chains; a real subset of properties, often in resort areas, require 21 — set by the hotel or franchisee, not the state.
• Not documented: Any Colorado-specific regulatory or municipal rule on check-in age beyond ordinary brand policy.
