New Colorado 2026 Security Deposit Laws: What Denver Landlords Can No Longer Deduct

Jan. 1, 2026, marked a seismic shift for every landlord operating in Denver. Colorado House Bill 25-1249 rewrote the rulebook on security deposits, and if you're still using lease templates from last year, you're walking into a legal minefield.

Here's what changed: Colorado now treats you as a fiduciary custodian of your tenant's deposit, not the owner of those funds. That distinction matters enormously. The money sitting in your account belongs to your tenant until you can prove, with documentation, that you're entitled to keep any portion of it.

The penalties for getting this wrong are severe. Courts can now award treble damages, meaning tenants can recover three times the deposit amount if you violate the new rules. A $1,500 deposit dispute can quickly become a $4,500 judgment against you, plus legal fees.

Denver's rental market has always required landlords to stay sharp, but this 2026 Colorado security deposit law demands a complete operational overhaul. The deductions you’ve made routinely for years — like carpet replacement, repainting, or general cleaning — are now either prohibited outright or require extensive documentation to justify.

This isn't about being tenant-friendly or landlord-friendly. The legislature designed these rules to eliminate the gray areas that generated thousands of small claims court cases annually. Whether you manage one rental property or twenty, understanding what Denver landlords can no longer deduct is now non-negotiable for protecting your investment.

Colorado’s New One-Month Cap and Security Deposit Installment Payments

Forget everything you knew about collecting deposits upfront. The days of requesting first month's rent, last month's rent, and a double deposit are over. HB25-1249 caps security deposits at exactly one month's rent, period.

This cap applies regardless of the tenant's credit score, rental history, or any other risk factor you might have used to justify higher deposits in the past. A $2,000 monthly rent means a $2,000 maximum deposit. No exceptions, no workarounds, no creative fee structures to pad that number.

The installment provision adds another layer of complexity. Tenants now have the legal right to pay their security deposit over six months rather than all at once. If your monthly rent is $1,800, a tenant can pay $300 per month toward their deposit while also paying rent.

From a vacancy perspective, this actually helps. You can fill units faster because prospective tenants no longer need $5,000 or more upfront to move in. However, your accounting needs to track partial deposits meticulously. You must know exactly how much of the deposit has been collected at any given time, and your records need to reflect this clearly if a dispute arises.

The practical challenge is cash flow management during those first six months. If a tenant damages the property in month three and has only paid half their deposit, your recovery options are limited. Build this reality into your tenant screening process and understand that the deposit cap means screening quality matters more than ever.

Redefining "Normal Wear And Tear" for 2026: Colorado’s 10-Year Carpet Rule and More

The phrase "normal wear and tear" has sparked more landlord-tenant disputes than almost any other term in rental law. HB25-1249 eliminates much of the ambiguity by explicitly listing what you can’t charge tenants for, creating a firm definition of what constitutes normal wear and tear — and what doesn’t.

Carpet buckling from regular foot traffic is now protected. Wall scuffs from furniture placement and daily living activities can’t be deducted. General deterioration that occurs simply because someone lived in the space for a year or more falls squarely into the protected category.

The "10-year carpet rule" deserves special attention. If your rental property has carpet that's a decade old or older, you can’t deduct for carpet replacement, regardless of condition. The law presumes that carpet has reached the end of its useful life after ten years of normal use. Keep installation receipts and records, because proving carpet age will become crucial in disputes.

Repainting restrictions follow similar logic. You can only deduct for repainting if there's substantial damage beyond normal use. Crayon marks in a child's bedroom, smoke staining from unauthorized smoking, or large holes from mounted TVs might qualify. Minor nail holes, slight discoloration, or fading from sunlight exposure do not.

The standard you should apply is this: Would this condition exist if the tenant had lived normally in the space for the lease term? If yes, you can’t deduct for it. Document everything at move-in with dated photos, because your ability to prove that damage exceeded normal wear now determines whether you can retain any portion of the deposit.

The 14-Day Documentation Rule

Speed and thoroughness now determine whether your deductions survive scrutiny. When you withhold any portion of a security deposit, tenants can request documentation supporting those deductions. You have exactly 14 days from their request to provide photos, receipts, and invoices.

Missing this deadline isn't just an inconvenience. Failure to provide documentation within 14 days creates a legal presumption of bad faith. Once you’re presumed to be operating in bad faith, you're fighting uphill in any court proceeding, and treble damages become a real possibility.

Your documentation package should include:

• Dated move-in photos showing the property's condition before occupancy
• Dated move-out photos showing the specific damage you're claiming
• Itemized receipts for all repairs or cleaning
• Invoices from contractors or service providers
• A clear written explanation connecting each deduction to specific damage

The requirement to provide receipts and invoices means you can’t simply estimate repair costs. If you're deducting $200 for cleaning, you need a receipt from a cleaning service for that amount. If you're claiming $500 for drywall repair, you need an invoice from the contractor who performed the work.

Building this documentation habit into your turnover process is essential. Photograph everything before and after every tenancy. Keep organized files for each property. The landlord who treats documentation as an afterthought will lose deposit disputes, even when the deductions were legitimate.

Conducting Walk-Throughs the Right Way 

Tenants now have the explicit right to request a final walk-through after their furniture and belongings are removed. This isn't optional if they ask for it. Refusing or ignoring this request creates problems you don't want.

The timing matters. The walk-through should happen after the tenant has fully vacated but before you begin any repairs or cleaning. This gives both parties a clear view of the property's actual condition at the moment of surrender.

If scheduling an in-person walk-through proves impossible due to distance, conflicting schedules, or other logistics, virtual walk-throughs are acceptable. Use video calls to walk through the property together, documenting as you go. Record the session if both parties consent, and take screenshots of any areas of concern.

Your move-in documentation becomes your primary defense during these walk-throughs. When a tenant disputes a claim of damage, you will need to show what that area looked like before they moved in. Side-by-side comparisons of move-in and move-out photos often resolve disputes before they escalate.

Consider implementing a standardized condition report that both parties sign at move-in and move-out. This creates a paper trail showing agreement on the property's condition at both ends of the tenancy. When disputes arise, having the tenant's signature acknowledging the move-in condition strengthens your position considerably.

Avoiding the "Bad Faith" Trap: How Bad Faith Security Deposit Retention Works in Colorado

The "125% rule" represents one of the most significant shifts in how courts will evaluate deposit disputes. If you retain an amount that equals or exceeds 125% of your actual documented damage costs, you're presumed to have acted in bad faith.

Let's make this concrete. You have $400 in legitimate, documented damages. If you keep $500 or more of the deposit, the law presumes you acted in bad faith. That presumption flips the entire dynamic of any court proceeding in the tenant's favor.

The burden of proof now sits squarely on your shoulders. In the past, tenants challenging deductions had to prove that you were wrong. Now, you must prove you were right. Every deduction needs documentation. Every charge needs justification. Every dollar retained needs a receipt behind it.

This rule essentially eliminates the practice of rounding up deductions or adding buffer amounts to cover potential issues. If your documented damages total $387.50, you should retain $387.50, not $400, not $500. Precision protects you.

The bad-faith finding triggers treble damages automatically. A $1,000 deposit dispute where you're found to have acted in bad faith becomes a $3,000 judgment. Add attorney fees, court costs, and the time investment of litigation, and what seemed like a minor dispute becomes a significant financial hit.

Risk scenarios to avoid: deducting for cleaning without a cleaning receipt, estimating repair costs without contractor invoices, retaining portions of deposits for items that fall under normal wear and tear, or simply keeping the full deposit because you're angry about how the tenant left the property.

Conclusion: How the New Colorado Security Deposit Law Will Affect You in 2026

Being a DIY landlord in Denver has become significantly more complex. The administrative burden of proper documentation, the tight timelines for providing proof, the restrictions on what you can deduct, and the severe penalties for mistakes create a landscape where small errors carry outsized consequences.

The margin for error is razor-thin. One missed deadline, one undocumented deduction, or one carpet replacement charge on 11-year-old flooring can trigger treble damages and turn a routine turnover into a costly legal battle.

FAQs

Can I charge a non-refundable cleaning fee?

No. HB25-1249 voids automatic cleaning deductions and non-refundable cleaning fees. You can only deduct for cleaning if the tenant left the property in a condition that exceeds normal use, and you have receipts from a cleaning service documenting the actual cost. The days of standard $150 cleaning deductions regardless of condition are over.

What if the tenant leaves without providing a forwarding address?

You must hold the refund check for at least one year. Make reasonable efforts to locate the tenant, including checking with the post office for forwarding information. Document your attempts to deliver the refund. After one year, unclaimed deposits may be subject to Colorado's unclaimed property laws, which require reporting to the state.

Can I call a security deposit a move-in fee?

No. The law explicitly forbids mislabeling fees to circumvent the one-month deposit cap. Calling something a "move-in fee," an "administrative fee," or any other name while treating it as a damage reserve violates the statute. Courts will look at the substance of the charge, not the label you give it.

Does this apply to commercial units?

Current legislative intent suggests HB25-1249 applies primarily to residential properties. Commercial leases operate under different legal frameworks and typically involve more negotiated terms between parties with relatively equal bargaining power. However, mixed-use properties with residential units should assume the residential portions fall under these new rules. Consult with a real estate attorney if your property situation is ambiguous.
