Is a Nonrefundable Deposit Legal in Colorado?

You hand over a deposit at signing, and somewhere in the paperwork one word does a lot of quiet work: “nonrefundable.” It sounds final — money you’ll never see again no matter how spotless you leave the place. But a word printed in a lease and what Colorado law actually requires aren’t always the same thing. If you’ve ever watched a deposit vanish for reasons that never quite added up, this is the homework that helps you sign with clear eyes.

This is educational, not legal advice, and every situation is different. But the deposit-vs- label question is one worth understanding before you sign.

A security deposit is refundable by law

Start with what a security deposit is. It’s money you put up to secure the unit — protection for the landlord against damage beyond normal wear, or unpaid rent. Colorado law treats it as your money being held, not the landlord’s money being earned. After you move out, the landlord has to return it, minus any lawful, itemized deductions, within the timeframe the law sets (C.R.S. 38-12-103).

That return duty is the important part. Labeling a security deposit “nonrefundable” doesn’t override it. Colorado doesn’t hand a landlord a way to keep your deposit just by printing a word next to it — what you’re owed back is determined by the law and by what deductions the landlord can actually justify, not by the label.

Ask this: Is this money a security deposit — and if so, how and when do I get it back?

So where does “nonrefundable” come from?

Two places, and it’s worth telling them apart.

• A genuine fee for a real service. A one-time charge for something the landlord actually provides — an application fee, for instance — is a fee, not a deposit. Fees like that can be nonrefundable because you’re paying for a service, not putting up security.
• A deposit wearing a fee’s name. This is the one to watch. A large “move-in fee,” “administrative fee,” or “cleaning fee” that behaves exactly like a deposit — held against the condition of the unit, charged regardless of how you leave it — is the kind of charge worth questioning. Calling security money a nonrefundable “fee” doesn’t automatically make it one.

Colorado looks at what a charge does, not only what it’s called. A modest, clearly defined charge for a real service is ordinary. The question is whether a “nonrefundable” line is doing a deposit’s job while wearing a different label.

Ask this: What service is this fee actually paying for — and would I be charged it even if I left the unit clean and undamaged?

What Colorado’s 2026 deposit changes actually did

You may have seen that Colorado changed its security-deposit rules for 2026. Here’s what the update (HB25-1249, effective January 1, 2026) actually does, because it’s easy to misremember:

• The maximum security deposit dropped to one month’s rent (down from two).
• Landlords must let you pay the deposit in installments over several months.
• A landlord who wrongfully keeps your deposit can owe up to three times the amount.
• The return window is generally 30 days (a lease can extend it up to 60).
• There are tighter rules on what counts as normal wear and tear and what can be deducted.

Notice what’s not on that list: it isn’t a law about the word “nonrefundable.” The real protection is simpler and older — your deposit has to be returned, minus lawful deductions, and the label doesn’t change that.

Getting the answer in writing

The single most useful habit costs nothing: move the important answers from conversation to writing. If a landlord tells you the cleaning fee is “just standard” or the deposit is “nonrefundable, that’s our policy,” a short, polite email confirming what you were told — and what comes back to you at move-out — gives you a record if it’s ever questioned later.

You’re not being difficult. You’re doing exactly what a careful person does with any agreement about their own money. For the fuller list of deposit questions worth asking up front, see the security-deposit questions every Colorado renter should ask.

The bottom line

A “nonrefundable” label isn’t automatically the last word — a security deposit stays refundable by law, minus lawful deductions, no matter what the lease calls it. The real cost of these terms is that they sound settled: they can discourage you from asking for money you’re owed. Spotting the deposit-versus-fee question before you sign puts you back in the conversation, so you can ask, negotiate, or at least sign knowing which charges should come back.
