What to Do if Your Landlord Breaks a Lease in Colorado

When you sign a lease in Colorado, both you and your landlord are expected to follow its terms. But what happens if your landlord breaks the lease agreement—for example, by asking you to leave early or by failing to provide agreed-upon maintenance? Understanding your renter rights and the right steps to take is essential for protecting your home and peace of mind in Colorado.

Understanding Lease Violations by Landlords in Colorado

A lease is a legally binding contract under Colorado law. Your landlord can "break" a lease in several ways, such as:

  • Ending your tenancy early without valid reason
  • Raising rent outside your lease terms or local law
  • Not performing critical repairs or maintenance as promised
  • Failing to return your security deposit as required

For residential rental agreements, the key legislation is the Colorado Revised Statutes, Title 38, Article 12 – Colorado Residential Tenants Act[1].

Immediate Steps for Colorado Renters if Your Landlord Breaks the Lease

  • Document Everything: Keep copies of your lease, correspondence, photos, and records of any broken promises or violations.
  • Communicate in Writing: Politely notify your landlord of the issue using email, certified mail, or written letter—keep a copy.
  • Review Colorado Law: Learn your rights under the Colorado Residential Tenants Act.
  • Give Notice if Needed: For most lease violations (e.g. failure to repair), send a written demand using a legal notice form (explained below).

In most cases, you’ll need to give your landlord a reasonable chance to fix the problem before taking further steps.

Official Forms and How to Use Them

  • Notice to Landlord of Breach (typically 7-Day Demand for Compliance): Colorado does not provide a universal state form, but you may use a written letter or for habitability issues, provide a "Notice of Violation – Warranty of Habitability". This informs your landlord of the problem and gives them a set number of days (usually 7) to fix it as per C.R.S. § 38-12-503.
    Example: If your landlord fails to repair your heater in winter, you may submit this notice. If repairs aren’t made, you may seek other remedies.
    Official Notice guidance: Colorado Division of Housing – Landlord/Tenant Handbook.
  • Small Claims Complaint (JDF 250): Use this to sue your landlord for damages (like unreturned security deposit) up to $7,500 in Colorado Small Claims Court.
    When to use: After proper notice and waiting period, and if no resolution occurs.
    Find the JDF 250 Complaint Form (PDF) and full instructions on the Colorado Judicial Branch website.

Which Tribunal Handles Lease Disputes in Colorado?

Most residential lease disputes and eviction cases are handled by the Colorado Judicial Branch – County Courts. For habitability complaints, renters may also contact the Colorado Division of Housing for guidance or further action.

What If the Breach Is Not Fixed? Further Actions for Renters

If your landlord does not resolve the violation after you provide written notice:

  • You may withhold rent only in specific habitability situations and must follow state law carefully. Review state guidance or seek legal advice before doing so.
  • You can file a claim in Small Claims Court (using JDF 250) for damages like a security deposit not returned after proper notice.
  • For illegal evictions or lockouts ("self-help" evictions), you may request an immediate hearing or seek a restraining order through the County Court.
Tip: If safety or habitability is at risk, seek help immediately from local housing agencies or legal aid.

Colorado laws offer strong protections, but you must follow official notice and documentation procedures to exercise your rights.
