Colorado Security Deposit 7-Day Demand Letter & Template Guide

If your Colorado landlord has wrongfully withheld your security deposit, state law gives you the power to fight back. Under C.R.S. § 38-12-103, sending a formal 7-day demand letter is the mandatory first step to holding them liable for triple the amount withheld, plus your attorney fees.

What the Law Says in Colorado

In Colorado, landlords cannot simply keep your money or make up arbitrary reasons to pocket your security deposit. Under Colorado Revised Statutes § 38-12-103, a landlord has 30 days (or up to 60 days if explicitly stated in your lease agreement) from the time you move out or surrender the keys to return your full deposit or provide a written, itemized list of deductions. If they fail to provide this statement or return your money within this timeframe, they forfeit all rights to withhold any portion of your security deposit under C.R.S. § 38-12-102(2).

Furthermore, Colorado law strictly prohibits landlords from deducting for 'normal wear and tear'—minor deterioration that occurs naturally from living in a property. If they do withhold funds unlawfully, the law provides a powerful weapon: treble damages. Under C.R.S. § 38-12-103(3)(a), a landlord who willfully retains your deposit is liable for three times (treble) the wrongfully withheld amount, plus reasonable attorney fees and court costs. However, to unlock this penalty, you must first notify them of your intent to file legal proceedings by serving a formal 7-Day Demand Letter. This letter gives them one final week to pay up or face severe financial consequences in court.

How to Use the 7-Day Demand Letter Template

Your demand letter must be precise, professional, and properly served to protect your right to treble damages. You can draft this letter using our template format. Start by stating the clear facts: the date your lease terminated, the amount of the deposit paid, and the exact date you vacated. If they sent you an itemized list of deductions that you dispute (such as charging you to paint walls or clean carpets that only had normal wear and tear), list these disputed items explicitly and state why they are unlawful.

If they missed their 30-to-60-day statutory window entirely, your letter should clearly state that they have forfeited all rights to withhold any money under C.R.S. § 38-12-103(2). Conclude the letter with the explicit warning: if they do not return the specified amount within seven days of receiving the notice, you intend to file legal proceedings and will seek triple damages, court costs, and reasonable attorney fees. Send this letter via Certified Mail with a return receipt requested, or hand-deliver it with a signed acknowledgment of receipt. This paper trail is your key piece of evidence if you have to go to court.

What to Do Next

Once your former landlord receives the 7-day demand, they have exactly one week to return your funds. In many cases, landlords who were counting on you to stay quiet will quickly pay up to avoid paying treble damages and your legal fees. If they ignore the letter or refuse to cooperate, your next step is to file a lawsuit in Colorado Small Claims Court. Under C.R.S. § 13-6-403, you can sue for up to $7,500 (exclusive of interest and costs), which makes it a highly effective and relatively fast route to recover your money without complex legal procedures.

Remember, when you go to court, the law is on your side: C.R.S. § 38-12-103(3)(b) explicitly states that the landlord bears the burden of proving that their withholding was not wrongful. You do not have to struggle through this stressful process alone.

Steps

• Verify the deadline: Check your lease to see if the return window was extended. If the lease does not specify, the deadline is 30 days. If specified, it can be up to 60 days.
• Draft the 7-day demand letter: Use a template citing C.R.S. § 38-12-103, detailing your move-out date, forwarding address, the amount owed, and disputing any unfair 'wear and tear' deductions.
• Send the letter via certified mail: Mail the letter with 'Certified Mail, Return Receipt Requested' or deliver it in person with a witness. Keep a copy of the signed letter and the post office receipt.
• Track the timeline: Wait exactly 7 days from the date the landlord received the letter. If they do not return the full requested amount, prepare your Colorado Small Claims Court filing.

Common mistakes

• Failing to send a formal 7-day demand letter before suing, which completely waives your right to recover triple (treble) damages and attorney fees.
• Accepting a partial refund check that has restrictive endorsement language (like 'payment in full' or 'accord and satisfaction') without first consulting a lawyer.
• Neglecting to document the property's condition with photos and videos when moving out, leaving you with less evidence if the landlord invents damages.

Questions people ask

Can my landlord deduct for cleaning or carpet replacement under Colorado law?

Only if there is damage beyond normal wear and tear. Under C.R.S. § 38-12-103, landlords cannot charge you for standard cleaning or carpet wear that naturally results from everyday living. If they deduct for these, they must prove the damage was excessive.

What happens if I didn't give my landlord a forwarding address?

Under Colorado law, if you do not provide a forwarding address, the landlord complies with the statute by mailing the itemized statement and any refund check to your last known address (the rental property you just vacated). You must set up mail forwarding with USPS to ensure you receive it.

How much does it cost to sue my landlord in Colorado Small Claims Court?

Filing fees in Colorado Small Claims Court are relatively low, typically ranging from $31 to $55 depending on the amount you are claiming. If you win your case, the court can order your landlord to reimburse you for these court costs, plus reasonable attorney fees if you hired representation.
