Colorado Security Deposit Law, Explained for Property Managers

Security deposits are the single most litigated dollar in residential property management, and Colorado just raised the stakes. HB25-1249 was signed on June 3, 2025 and took effect January 1, 2026, rewriting parts of C.R.S. 38-12-103. If your move-out process still looks the way it did in 2024, you are now carrying real exposure. Here is what changed, what it means operationally, and where the traps are.

The three numbers that matter

The default clock is thirty days after the termination of the lease or surrender and acceptance of the premises, whichever happens last. A lease may specify a longer period, but it cannot exceed sixty days. One of the quieter changes in HB25-1249 is that the statute now says thirty days rather than the older phrase one month. That sounds cosmetic. It is not. A February move-out under the old language could arguably give you twenty-eight days; under the new language you get thirty. More importantly, it removes the ambiguity your team was probably resolving in whichever direction was most convenient.

Miss the deadline and you forfeit everything

This is the provision that punishes sloppy operations rather than bad intent. If you fail to provide the required written itemized statement within the required time, you forfeit your right to withhold any portion of the deposit. Not the disputed portion. Any portion. A legitimate 2,400 dollar carpet claim becomes zero because a statement went out on day 32.

HB25-1249 extends this forfeiture logic further: a landlord who does not comply with the requirements of section 38-12-103, or who otherwise wrongfully withholds a deposit, forfeits the right to withhold any portion of it. Compliance is now the gate, not just timeliness.

• Start the clock at the correct trigger event, not at the date you got around to the inspection.
• Send the itemized statement and any refund together, to the last known address of the tenant.
• Log the send date and keep proof. In a dispute, the landlord carries the burden of proof.

Normal wear and tear was redefined, and it got broader

You have never been allowed to charge a resident for normal wear and tear. What changed is the definition. The Colorado Division of Real Estate describes the updated language as deterioration, damage, or uncleanliness that occurs based upon the use for which a rental unit is intended or reasonably and typically used, without negligence, carelessness, accident, or abuse of the premises.

Read that twice. The words damage and uncleanliness are now inside the definition of normal wear and tear. Scuffed paint after a three-year tenancy, worn traffic lanes in carpet, a bit of ordinary grime: those are protected. The one carve-out the Division highlights is that normal wear and tear does not include uncleanliness that leaves the unit substantially less clean than it was when the lease began. So a genuinely filthy unit is still chargeable. A lightly used one is not.

The statute also makes it void, as against public policy, to put a clause in a lease that assigns a fee or charge to a tenant for repairs, cleaning, or other necessary work caused by normal wear and tear, or for any damage or defective condition that preexisted the tenancy. If your lease still contains a flat mandatory carpet cleaning fee or a standard turn fee, that clause deserves an urgent look from counsel.

Deduct for the damage, not for the upgrade

The practical rule that Colorado practitioners are converging on is proportionality. If one section of carpet is damaged beyond normal wear and tear and that section can be replaced, you charge for that section, not for a full replacement. If three walls need paint, you do not bill the fourth. Turning a move-out into a funded renovation is exactly the behavior the bad-faith provisions are aimed at.

The walk-through is now a right, and skipping it is expensive

Either the landlord or the tenant may request a walk-through before the end of the lease term, after the tenant has had the opportunity to remove furniture. It can be done in person or through a telecommunication-assisted interactive walk-through, which is a meaningful concession to how small teams actually operate. If a walk-through is requested and you do not provide it, you are in the forfeiture zone described above.

1. Put the walk-through offer in your notice-to-vacate acknowledgment so the request never arrives as a surprise.
2. Schedule it at a mutually convenient time after the resident has cleared furniture, so what you photograph is the actual condition.
3. Document the walk-through itself: date, participants, and a timestamped photo set. A video call recording counts as a record.

Bad faith now has a definition, and a bright line

Willful retention of a deposit in violation of the statute makes a landlord liable for treble the wrongfully withheld amount, plus reasonable attorney fees and court costs. The tenant must give at least seven days notice of intent to file before suing. That part is not new. What is new is that the Division of Real Estate now lays out when a deposit is deemed withheld in bad faith, including when the amount retained unreasonably exceeds actual damages incurred, when there is no actual cause for the retention, when the landlord knew or should have known the retained amount exceeded actual damages, or when the retention is for an unlawful, retaliatory, or discriminatory purpose.

The number to burn into your process: unreasonably exceeds is presumed at 125 percent or more of actual damages incurred. If you withhold 500 dollars against 300 dollars of real, documented cost, you are on the wrong side of a presumption in a proceeding where you already carry the burden of proof. Estimate high and you invite the treble.

Two more things that quietly bite

• Ownership transfers. If the landlord interest terminates by sale, assignment, death, or receivership, the party holding the deposit has sixty days to either transfer the funds to the successor in interest and notify the tenant by mail of the transfer and the transferee name and address, or return the funds to the tenant. In an acquisition, deposits are a liability you must actively hand off, not a balance that quietly rides along.
• The deposit cap. The maximum deposit rule lives in C.R.S. 38-12-102.5, separate from the return rules in 38-12-103, and the 2025 session touched this area. Confirm the current cap and any installment obligations with counsel before you set deposit amounts for a new lease. Do not rely on a number you memorized in 2023.

The compliance checklist

1. Move-in condition report with photos, signed by the resident. Without a baseline you cannot prove a condition preexisted the tenancy, and you will lose that argument.
2. Offer the walk-through in writing at notice-to-vacate, and honor every request.
3. Deduct only actual, documented, proportional cost. Attach invoices and photos to every line.
4. Send the itemized statement plus refund inside the deadline your lease actually specifies, and keep proof of the send.
5. Retain the file. The landlord bears the burden of proving the withholding was not wrongful and that the statute was followed.

The takeaway

Colorado did not just tighten a deadline. It shifted the deposit from something you hold to something you must actively justify, with the burden on you, a bright-line bad-faith presumption at 125 percent, and total forfeiture as the penalty for procedural failure. The good news is that this is an operations problem, not a legal one. Managers who photograph everything, deduct only what they can invoice, and never miss a clock will find the new law almost boring. Managers who eyeball a number on day 33 will find it very expensive. Have a Colorado attorney review your lease and your move-out packet before your next turn season.
