How to Write a Demand Letter to Your Colorado Landlord

If you’re a renter facing problems like delayed repairs, unreturned security deposits, or rent disputes in Colorado, sending a demand letter to your landlord can be an important first step. This letter is a formal written request asking your landlord to fix an issue, comply with the law, or meet their obligations. It's a critical step before pursuing legal action or involving a government agency.

What Is a Demand Letter and Why Send One?

A demand letter is a written request sent to your landlord describing a problem and clearly stating what action you want them to take. In Colorado, it can help you document efforts to resolve a dispute, show good faith, and is often required before taking a landlord to court or seeking state intervention.

  • It provides written evidence of your concerns and requests.
  • It may encourage your landlord to resolve the issue without legal action.
  • It can be required for issues like return of deposits or habitability concerns under Colorado law.

When Should You Write a Demand Letter?

Consider writing a demand letter if:

  • Your landlord is not making necessary repairs
  • They have not returned your security deposit within the required period
  • There are disagreements about rent increases, lease terms, or eviction notices

Giving your landlord a clear, written opportunity to address the issue may resolve matters quickly and strengthens your case if you need to escalate.

Key Legal Requirements in Colorado

Colorado’s Colorado Revised Statutes Title 38, Article 12: Landlord and Tenant Law governs rental agreements and tenant rights. Under these laws, specific procedures apply to common disputes, and some issues (like security deposit returns) require a written demand before you can take the matter to court.[1]

Important Tribunal for Colorado Renters

Housing-related disputes in Colorado are typically handled by the local county courts. Statewide housing information is provided by the Colorado Department of Local Affairs - Division of Housing, which also offers guidance and mediation services.[2]

It’s also a good idea to keep a copy for your records and send it using a method that confirms delivery, such as certified mail or email with a read receipt.

Sample Outline for Your Demand Letter

  1. Date and your contact information

  3. Subject line: "Demand for [Repair/Security Deposit Return/etc.]"
  4. Description of the issue (with dates/evidence)
  5. What action you want and a deadline
  6. Reference applicable lease terms or laws
  7. Statement that you may take further action if it’s unresolved

Relevant Forms and Resources for Colorado Renters

  • Security Deposit Demand Letter: While Colorado doesn't have a standard state-issued form, you may use a template such as the Division of Housing Security Deposit Letter Sample. Use this after moving out if your deposit is not returned within the legal timeframe (usually one month after you vacate unless your lease allows up to 60 days).
  • Notice of Intent to Withhold Rent for Repairs: Colorado requires you to notify your landlord in writing of repair needs before you can consider withholding rent or making repairs yourself. See the "Request for Repairs" template on the official Colorado Division of Housing renter resources page for examples.
  • Small Claims Complaint (JDF 250): If your demand letter does not result in a resolution, you may consider filing a small claims case. The form and instructions are available from the Colorado Judicial Branch Small Claims Forms page.

Remember, demand letters are not court actions, but they lay the groundwork for resolving your dispute or pursuing formal action if needed.

What Happens After Sending Your Demand Letter?

  • The landlord may resolve the issue or contact you to negotiate.
  • If there’s no response, you may consider mediation or file with small claims court.
  • Keep all documentation — it can support your case in court or in government proceedings.

Patience is important: Colorado law may require you to give the landlord a reasonable period (often 7 days, but longer for some deposits) before taking further action.

FAQ: Demand Letters and Colorado Renter Disputes
