Colorado Eviction Notices:
A Tenant's Complete Guide

Getting a notice from your landlord is alarming. The word "eviction" carries weight — the fear of losing your home, not knowing what comes next, wondering whether you have any rights at all. That fear is understandable. But here is something important to know from the start: receiving a notice is not the same as being evicted. There is a legal process between the two, and at every stage of that process you have rights.

This guide explains what the different types of Colorado eviction notices mean, what happens after one is served, what the court process looks like if it gets that far, and what you should — and should not — do at each stage. Colorado's eviction protections have strengthened significantly in recent years. Understanding them puts you in a fundamentally better position than not knowing them.

First: A Notice Is Not an Eviction

In Colorado, a landlord cannot simply remove you from your home. The law requires a specific sequence: first a written notice, then — if you do not comply or vacate — a court filing, then a hearing, and only after a court judgment can a landlord obtain a writ of restitution authorizing law enforcement to remove you. That process takes time, and you have the opportunity to respond at every step.

A notice is a legal prerequisite. It gives you a window to cure the issue, pay what is owed, or make a decision about next steps before your landlord can take you to court. That window matters. How you use it — and what you do and do not do during it — can significantly affect what happens next.

The Notice Types — What Each One Means

Colorado law provides for several distinct types of eviction notices, each applying to different situations. The type of notice you received tells you a great deal about where you stand and what options you have.

Demand for Compliance or Right to Cure

This is the most common notice for lease violations that are not related to nonpayment of rent. If your landlord believes you have violated a lease term — an unauthorized pet, an unauthorized occupant, a noise issue, a lease provision you are not following — they must first give you a chance to cure the problem before filing to evict.

The cure period is generally 10 days, though it may extend to 30 days if the property is backed by a federally backed mortgage. In certain circumstances it may be as few as five days. If you cure the violation within the notice period, the landlord generally cannot proceed with eviction based on that violation.

Read the notice carefully: it should specify exactly what lease provision is alleged to have been violated and when the notice expires. If the allegation is vague, inaccurate, or you dispute it, that matters — and it is worth discussing with an attorney before the deadline passes.

Demand for Rent or Possession

This is the nonpayment notice. If you have not paid rent when it is due, your landlord can serve a demand requiring you to pay the full amount of rent owed or vacate. The standard demand period is generally 10 days, and may be 30 days if the property is backed by a federally backed mortgage; in certain circumstances it may be as few as five days.

A few critical points. First, a landlord can only demand rent that is actually owed — demanding unowed rent or improperly characterized fees can undermine the validity of the notice. Second, Colorado law does not permit a landlord to evict a tenant solely based on nonpayment of late fees. Late fees are not rent, and a demand premised on late fees alone, or that conflates late fees with rent owed, is on shaky legal ground. Third, if you pay the full amount of rent owed within the notice period, the landlord cannot proceed with eviction based on that nonpayment.

If you have a habitability claim — meaning your landlord has breached the Warranty of Habitability and failed to make required repairs after proper notice — that breach may be relevant to your rent obligation and could be a defense in an eviction proceeding. Our Colorado Habitability Rights guide covers the Warranty of Habitability in depth, including what conditions qualify, the notice and repair timelines your landlord must follow, and how a habitability breach can be raised as a defense.

Notice to Terminate Tenancy for Substantial Violation (3-Day)

This is a more serious notice. A landlord can serve a 3-day notice to terminate tenancy — with no opportunity to cure — when they allege a "substantial violation" of the lease. Colorado law defines substantial violations to include things like criminal activity on the premises, causing significant damage to the property, or conduct that threatens the health or safety of others.

Unlike the standard demand for compliance, a substantial violation notice does not give you the opportunity to fix the problem and stay. The landlord is saying the violation is serious enough that they are terminating the tenancy outright. If you receive one of these, understanding whether the underlying allegation actually qualifies as a substantial violation — and whether the notice was properly served — is critical. Do not assume a notice labeled "substantial violation" is legally unassailable. Consult an attorney.

Notice to Terminate Tenancy — Month-to-Month (21-Day)

If you are on a month-to-month tenancy and have been in the unit for less than one year, your landlord can terminate the tenancy without cause by giving you 21 days' written notice before the end of a rental period. This notice does not require any allegation of wrongdoing — it is simply terminating the tenancy at the end of the current rental period with proper notice.

However — and this is important — once you have lived in a unit for one year or more, or have a lease of one year or longer, the calculus changes dramatically. Colorado's just-cause eviction law, HB24-1098, significantly restricts a landlord's ability to terminate without a valid reason once that threshold is crossed. That law is addressed in detail in the next section.

No-Fault Notice to Terminate Tenancy (90-Day)

For tenants who qualify for just-cause protections, a landlord who wants to end the tenancy for a "no-fault" reason — one that is not based on anything the tenant did wrong — must give at least 90 days' written notice. The valid no-fault reasons are limited by statute, and are covered in the just-cause section below.

Just-Cause Eviction Protections Under HB24-1098

In 2024, Colorado enacted one of the most significant expansions of tenant protections in the state's history. HB24-1098 established a just-cause eviction requirement for qualifying residential tenants — meaning landlords must have a legally valid reason to evict or to refuse to renew a lease.

Who Is Protected

Just-cause protections apply to you if either of the following is true:

• You have a lease of one year or longer — even if that lease is verbal, or
• You have resided in the unit for one year or more, regardless of whether your lease has expired or you are now month-to-month

If you have been in your home for a year or more, you almost certainly have just-cause protection. The length of your tenancy is what matters most — not the current status or form of your lease.

Valid "For-Cause" Reasons for Eviction

Under HB24-1098, a landlord with a just-cause tenant can still evict — but only for valid reasons. These include:

• Nonpayment of rent — after proper notice and an opportunity to pay
• Lease violation — after proper notice and an opportunity to cure (for curable violations)
• Substantial violation — criminal activity, significant damage, threats to safety
• Refusal to sign a new lease with reasonably similar terms upon expiration of the existing lease
• Nuisance conduct — repeated behavior that substantially interferes with others' enjoyment of the property

Valid "No-Fault" Reasons — and the 90-Day Notice Requirement

Even with just-cause protection, there are limited circumstances where a landlord can end your tenancy without any wrongdoing on your part — but they must give you at least 90 days' written notice, and the reason must fit within the statutory categories. Valid no-fault reasons include:

• The landlord or a qualified family member intends to occupy the unit as their primary residence
• The landlord is selling the unit to a buyer
• Substantial renovation or demolition that requires the unit to be vacated and cannot be safely performed with the tenant in place
• Conversion to a non-residential use or removal from the rental market

HB24-1098 also prohibits landlords from refusing to renew a lease, or from failing to provide the proper notice timeframe, to circumvent these protections. The Colorado Supreme Court's decision in Miller v. Amos, 543 P.3d 393 (Colo. 2024), addressed related procedural requirements in the context of FED proceedings — a reminder that the procedural rules governing these disputes matter, and that tenants who understand them are better positioned to protect their rights.

Who Is Not Protected

Just-cause protections under HB24-1098 do not apply to every rental situation. They generally do not cover:

• Tenants in single-family homes or adjoining properties where the landlord currently lives on site
• Certain short-term rental arrangements
• Tenants who have been in the unit for less than one year and do not have a year-or-longer lease

If you are unsure whether just-cause protections apply to your tenancy, that is a question worth getting answered before you make any decisions.

If a Court Case Is Filed: The FED Process

If you receive a notice and do not comply — either because you cannot, will not, or dispute the basis for it — and the landlord decides to proceed, they must file a Forcible Entry and Detainer lawsuit in the county court where the property is located. This is a civil court action, and it is the only legal mechanism through which a landlord can obtain a court order to remove you from your home. A landlord who attempts to remove you by any other means — changing locks, removing belongings, shutting off utilities — is acting illegally.

Once the landlord files, the court will set a return date. You will be served with a summons telling you when that return date is. Read the summons carefully. The return date window can be very short — sometimes as little as a week from the date you are served. If anything on the summons is unclear — what is required of you, where to appear, or what the deadline means — contact the landlord, their counsel, or the court clerk directly for clarification.

The Answer — The Single Most Important Step

The return date on your summons is not necessarily a required court appearance for a full hearing on the merits. It functions more as a filing deadline — specifically, the deadline by which you must file a written answer with the court. County court procedures vary from county to county — read your summons carefully to understand exactly what is required of you by that date in your specific jurisdiction, and contact the court or an attorney if you have any questions.

Filing a written answer is the single most important thing you can do after being served in an eviction case. Here is why: if you do not file an answer, or if you file it late, the landlord can seek and receive a default judgment against you — a court order in their favor — without you ever having the opportunity to tell your side or present your defenses. The case will simply be decided against you by default.

The answer form used in Colorado FED cases is JDF 103. This is what the form looks like and what the court will expect you to file:

An attorney is particularly valuable at the answer stage for two reasons. First, they can help you identify and assess your strongest defenses — and potentially counterclaims against the landlord. Second, and critically: your defenses at the hearing are generally limited to what you stated in your answer. Defenses not included in the answer may be waived. A poorly drafted or incomplete answer can foreclose arguments you might have otherwise had.

If a Hearing Is Set

If your case proceeds to a hearing after an answer is filed, you will have the opportunity to present your case to a judge. This is your chance to contest the eviction, raise the defenses you stated in your answer, and present supporting evidence.

Bring documentation: your lease, any notices you received, all written communications with your landlord, records of rent payments, photographs if relevant, and anything else that supports your position. Be prepared to explain your situation clearly and concisely.

Pay close attention to any directives from the court regarding the sharing of evidence and exhibits with the opposing side prior to the hearing. Colorado courts may require both parties to exchange exhibits in advance — failure to comply with those directives can result in evidence being excluded or other adverse consequences. Read every court order carefully and follow its instructions.

Remember — the defenses you raise at the hearing must have been included in your written answer. This is why the answer stage matters so much.

If the court enters judgment for the landlord, the landlord can request a writ of restitution — a court order directing law enforcement to remove you from the unit. If the case is dismissed, the landlord would need to file a new court case to proceed further; whether an entirely new notice would be required depends on the specific circumstances of the dismissal.

If the court enters judgment for you, the landlord cannot proceed with removal based on that case.

Defenses Available to Tenants

Colorado tenants facing eviction are not without recourse. Depending on the specific circumstances, one or more of the following defenses may be available — and must be raised in your written answer to preserve them.

Defective Notice

Eviction notices must comply with specific statutory requirements — the right form, the right content, proper service (including two attempts at personal service before posting), and the correct time period. A notice that is defective in any of these respects may be legally insufficient to support an eviction action. Common defects include: incorrect notice period, demands for unowed amounts or late fees, improper service method, or a notice that fails to specify the violation with sufficient clarity.

Warranty of Habitability Breach

Colorado's Warranty of Habitability requires landlords to maintain rental units in a habitable condition — and a landlord's failure to do so, after proper notice, can be raised as a defense in an eviction proceeding. This is particularly relevant when a landlord is pursuing eviction for nonpayment while simultaneously refusing to address a serious habitability condition. Our Colorado Habitability Rights guide explains the Warranty of Habitability in depth — what conditions qualify, what timelines your landlord must meet, and how this defense works in practice. When raising a habitability defense in your answer, tenants may also need to file a supporting affidavit with the court:

Just-Cause Violation

If you have been in your unit for a year or more and the landlord cannot establish a valid just-cause reason for the eviction under HB24-1098, that is a defense. This includes situations where the landlord did not provide the proper notice timeframe, served a no-fault notice that does not fit within the statutory categories, or attempted to evict for a reason that is not legally recognized as just cause.

Retaliation

Colorado law prohibits landlords from evicting a tenant in retaliation for the tenant exercising a legal right — such as reporting a habitability problem to a government agency, complaining to the landlord about conditions, or joining a tenants' union. If an eviction notice closely follows a protected tenant activity, retaliation may be a viable defense.

Procedural Defects in the Court Filing

FED cases have specific procedural requirements. If the landlord did not properly serve the summons, filed in the wrong court, failed to name the correct parties, or made other procedural errors, those defects may provide grounds to challenge the case. The Colorado Supreme Court's decision in Miller v. Amos, 543 P.3d 393 (Colo. 2024), is a reminder that procedural compliance in FED cases is not a formality — it is legally significant and can affect the outcome.

Mistakes That Hurt Tenants Most

1. Ignoring the Notice or the Court Case

This is the most costly mistake. A notice has an expiration date — missing it eliminates options. A court summons has a return date — not filing an answer almost always results in a default judgment against you. No matter how unjust the situation feels, engaging with the process is essential. The worst outcome is far more likely when a tenant does not respond.

Beyond the immediate consequences, an eviction — even one you did not deserve — remains on your civil court record for seven years. That record can make it significantly harder to rent again in the future. Landlords routinely run court record checks. A default judgment entered because a tenant did not respond is just as damaging on that record as one entered after a contested hearing. Engaging with the process protects not only your current home but your ability to rent in the future.

2. Moving Out Without Understanding Your Options

Some tenants, frightened by a notice or court filing, simply leave before the process plays out. Moving out does not eliminate your ability to contest an eviction — a landlord cannot legally evict someone who has already vacated. But it is important to stay vigilant: if you have moved out, a court case may still be filed against you, and a default judgment can be entered even if you are no longer in the unit. If you do move out, communicate it clearly to your landlord in writing.

Whether moving out is the right decision depends entirely on your circumstances. It may be the best path in some situations and the wrong move in others. Before you make that decision, understand your legal position — what defenses you have, what a judgment would mean for your rental history, and what your options are either way.

3. Paying Partial Rent and Assuming That Satisfies the Notice

A demand for rent requires payment of the full amount of rent owed. Paying a partial amount does not satisfy the notice and does not prevent the landlord from proceeding with an eviction action based on the remaining balance. If you cannot pay the full amount, get legal advice about your options — partial payment alone is not a safe harbor.

4. Communicating Without a Record

Everything you say to your landlord or their attorney during an eviction dispute should be in writing. Verbal agreements to extend a deadline, verbal acknowledgments, or verbal assurances that the landlord will drop the case are not enforceable and are difficult to prove. Keep everything in writing, and keep copies.

5. Waiting Too Long to Seek Legal Help

The timelines in eviction cases are short. A triage call you could have had a week before the answer deadline becomes far less useful after a default judgment has been entered. If you have any reason to think a landlord may file or has filed an eviction case, reaching out to an attorney early — even just for a brief assessment — gives you time to understand your position and prepare a proper answer.

When to Call an Attorney — and How Urgent It Is

Eviction is one of the areas of law where timing matters most. The same situation handled early versus late can produce dramatically different outcomes.

You Received a Notice

You have time — but use it. Read the notice carefully, understand what type it is, and note when it expires. If the notice is based on a lease violation you committed and you can cure it, cure it promptly and document that you did. If you believe the notice is wrong, defective, or based on something you dispute, speak with a tenant attorney before the deadline passes. Getting clarity on your options at this stage prevents missteps that cost you later.

A Court Case Has Been Filed and You Have Been Served

This is urgent. Read your summons immediately and carefully — note the return date, understand what is required of you, and be aware that the window may be as little as a week. Your first priority is filing a written answer before that deadline. Contact a tenant attorney as soon as you receive the summons. An attorney can help you identify your defenses and any counterclaims, and ensure your answer fully and accurately states them — because what you include in the answer determines what you can argue at the hearing.

A Hearing Is Scheduled — Imminent

This is extremely urgent. If your hearing is in the next few days, call today. Even if full representation is not possible on the timeline, a focused preparation session with an attorney can meaningfully change how you present your case. Walking into an eviction hearing without understanding your rights, your defenses, or the basic procedure puts you at a serious disadvantage.
