Landlord Sued in Colorado Small Claims Court: Defendant's Guide

You Got Served — Now What?

Security deposit disputes are one of the most common types of small claims cases in Colorado. If a former tenant has sued you, they are almost certainly alleging that you withheld their deposit without proper justification. The stakes are higher than the deposit amount alone — Colorado law can allow treble (triple) damages for willful wrongful retention if the tenant meets the statutory demand and notice requirements.

Here is how to respond as a landlord defendant.

The Treble-Damages Risk and HB 25-1249

Under C.R.S. § 38-12-103, willful wrongful retention can expose a landlord to treble the wrongfully withheld portion, plus reasonable attorney fees and court costs. To bring a treble-damages action, the tenant must give a written demand and notice of intent to sue and allow seven days for return; the action can proceed if the landlord does not return the deposit or withheld amount within that period. HB 25-1249, effective January 1, 2026, updated the statute, including its definition of bad-faith retention and the requirements for a written accounting.

If $2,000 was willfully and wrongfully withheld and the statutory notice requirements are met, treble damages could total $6,000, plus fees and costs. This is the single biggest risk landlords face in Colorado small claims court.

Under HB 25-1249, bad-faith retention includes keeping an amount that unreasonably exceeds actual damages, keeping a deposit without actual cause, keeping an amount the landlord knew or should have known exceeded actual damages, or keeping it for an unlawful, retaliatory, or discriminatory purpose. An amount retained at 125% or more of actual damages is presumed unreasonable.

The Deposit Return Timeline

Colorado law requires landlords to return the security deposit — or provide a written itemized accounting and any remaining amount — within 30 days after the lease ends or the premises are surrendered and accepted, whichever occurs later. The lease can set a longer period, up to 60 days.

Failing to provide the written statement on time forfeits the right to withhold any part of the deposit; untimely or incomplete statements and late return of the balance can also count as wrongful withholding under C.R.S. § 38-12-103. The accounting must be itemized and specific — a single line saying "cleaning and repairs: $1,200" is not sufficient.

What Evidence to Bring

To defend against a deposit claim, you need documented proof of the property's condition:

• Move-in inspection report — ideally signed by the tenant, showing the condition at the start of the tenancy.
• Move-out inspection report — documenting the condition after the tenant left.
• Photos — timestamped photos of any damage beyond normal wear and tear, taken after move-out and ideally compared against move-in photos.
• Repair receipts and invoices — actual costs incurred for repairs, not estimates.
• The lease — specifically the clauses regarding the security deposit, permitted deductions, and return timeline.
• Your written accounting — the itemized statement you sent (or should have sent) to the tenant.
• Proof of mailing — certified mail receipt or delivery confirmation showing when you sent the accounting.

Bring everything in triplicate: one copy for you, one for the magistrate, and one for the tenant.

Property Manager Representation

If you use a property manager, they may be able to represent you in small claims court under C.R.C.P. 509(b)(3). In landlord-tenant cases, a property manager who received the security deposits, collected rent, or executed the lease on the property owner's behalf is permitted to appear on the owner's behalf.

The property manager does not need to be a licensed attorney to represent you in small claims court under this specific exception.

Common Defenses

• Damage beyond normal wear and tear. Document it with photos and repair invoices. Normal wear and tear — scuffed walls, worn carpet, minor nail holes — cannot be deducted.
• Unpaid rent. If the tenant left owing rent, you can deduct it from the deposit (with proper accounting).
• Other lawful lease charges and necessary repairs. The statute allows reasonable amounts for other lawful charges listed in the lease and necessary repairs for damage beyond normal wear and tear that did not preexist the tenancy; document and itemize any deduction.
• Timely accounting sent. If you sent the accounting within the required timeline with proper itemization, that undercuts a bad-faith claim.
