Colorado's warranty of habitability is a non-waivable legal obligation that runs from move-in to move-out — and a 2024 overhaul under SB24-094 gave it real enforcement teeth, with repair timelines as short as 24 hours and penalties reaching three months' rent for retaliation.
This guide covers every practical requirement small landlords need to know: what conditions trigger a breach under C.R.S. § 38-12-503 and § 38-12-505, how the response-time clock works, what your lease must include starting January 1, 2025, and what happens if a tenant raises a habitability defense in an eviction case.
The 10-Step Colorado Habitability Compliance Checklist
Before drilling into each item, here is the full compliance list. If you can check every box, you're in a defensible position under Colorado's current law. If you can't, keep reading — the sections below explain exactly what's required and what happens if you fall short.
- Deliver a habitable unit at the start of every tenancy (C.R.S. § 38-12-503(1)).
- Maintain habitability continuously throughout the lease term (C.R.S. § 38-12-503(1)).
- Include the required bold, 12-point habitability disclosure in all leases signed on or after January 1, 2025.
- Specify in the lease exactly how and where tenants can report an uninhabitable condition.
- Respond to life-safety emergencies within 24 hours of notice (C.R.S. § 38-12-503(2)(b)(I)(A)).
- Respond to standard uninhabitable conditions within 72 hours (C.R.S. § 38-12-503(2)(b)(I)(B)).
- Document every maintenance complaint and every response with timestamps.
- Provide comparable temporary housing (within 5 miles) when a condition materially interferes with a tenant's life, health, or safety — for up to 60 days while repairs are made.
- Give the required radon disclosure before a new lease is signed (C.R.S. § 38-12-503(2.4) and § 38-12-803).
- Never retaliate against a tenant who reports a problem, withholds rent, or exercises any statutory remedy (C.R.S. § 38-12-509).
1–2. The Core Warranty: Fit for Human Habitation, Start to Finish
In every rental agreement, the landlord is deemed to warrant that the residential premises is fit for human habitation at the inception of the tenant's occupancy and that the landlord will maintain the residential premises as fit for human habitation throughout the entire period that the tenant lawfully occupies the residential premises or dwelling unit. That language comes directly from C.R.S. § 38-12-503(1), and it leaves no wiggle room: both move-in condition and ongoing condition count.
The warranty of habitability is a Colorado law that requires that nearly every rental unit in the state meet minimum safety and health standards. In most cases, if you rent your home, you are legally guaranteed a safe and healthy place to live. This is true whether you have a written lease or not. Your landlord cannot try to get around these requirements by trying to get you to waive them or agree to something different. As a practical matter, this means lease clauses purporting to have the tenant accept the unit "as-is" or waive repair rights are void and unenforceable.
In Colorado, SB24-094, "Safe Housing for Residential Tenants," modifies existing habitability laws and clarifies actions that may violate the warranty of habitability. The entire section of the law dealing with habitability was repealed and re-enacted with significant changes to the law. The new law defines what constitutes habitability and the procedures that landlords and tenants must follow when the tenant alleges a warranty of habitability claim. The new law is effective May 3, 2024.
3–4. Lease Disclosure Requirements (January 1, 2025)
On and after January 1, 2025, every rental agreement between a landlord and tenant must include a statement in at least twelve-point, bold-faced type that states that every tenant is entitled to safe and healthy housing under Colorado's warranty of habitability and that a landlord is prohibited by law from retaliating against a tenant in any manner for reporting unsafe conditions in the tenant's residential premises, requesting repairs, or seeking to enjoy the tenant's right to safe and healthy housing.
The law requires rental agreements entered after January 1, 2025, to add a statement regarding how and where a tenant can report and deliver written notice of an unsafe or uninhabitable condition. Leases starting after January 1, 2025, must include a bolded statement (in English and Spanish) about tenants' rights to safe housing and the landlord's prohibition against retaliation, plus contact information for reporting uninhabitable conditions. Note the bilingual requirement: if your lease is only in English, update it.
Under the new law, tenants can now report a problem through virtually any channel. When a resident claims a habitability issue, they can now give notice in any way that works for them — call, email, text, talking to the landlord directly, etc. Previously, it had to be in writing. This means your response clock can start from a verbal complaint. Treat every communication as a potential notice and document it immediately.
5–7. Response Timelines and the Rebuttable-Presumption Rules
This is where most small landlords get blindsided. Colorado law doesn't just set a duty to repair — it sets specific deadlines, and missing them creates a legal presumption that you breached the warranty. Once that presumption triggers, you bear the burden of proving you responded adequately.
A landlord breaches the warranty of habitability if the landlord has notice of the condition and has failed to commence remedial action within: (A) twenty-four hours, where the condition materially interferes with the tenant's life, health, or safety. Seventy-two hours applies where the residential premises are uninhabitable as described in C.R.S. § 38-12-505 or otherwise.
| Condition Type | Start Remediation Within | Rebuttable Presumption of Breach | Statute Reference |
|---|---|---|---|
| Life-safety emergency (no heat Oct–Apr, gas leak, sewage backup, no running water) | 24 hours | After 24–96 hours without action | C.R.S. § 38-12-503(2)(b)(I)(A) |
| Standard uninhabitable condition (mold, plumbing failure, broken locks, pest infestation) | 72 hours | After 7 days without resolution | C.R.S. § 38-12-503(2)(b)(I)(B); § 38-12-505 |
| Complex conditions requiring licensed contractor | Reasonable time | After 14 days without action | C.R.S. § 38-12-503 |
| Radon above EPA action level (4 pCi/L) | 180-day remediation window | Tenant may terminate lease after 180 days | C.R.S. § 38-12-803; § 38-12-503(2.4) |
Notwithstanding when remedial action must commence, a landlord must reasonably continue to make efforts to commence or continue performing remedial action to remedy or repair a condition that renders the tenant's residential premises uninhabitable and for which the landlord has notice. These efforts shall include prompt correspondence and good faith cooperation with the tenant and may require prompt correspondence and good faith cooperation with maintenance staff, third-party contractors, a government official, or any other person whose involvement is necessary to remedy or repair the condition. Scheduling a contractor and then going silent doesn't satisfy the law.
Your documentation discipline is your defense. The burden of proof shifts to the landlord to prove otherwise. In practice, this means a landlord who can't document their response timeline will likely lose in court. Log every complaint with the date and time received, every contractor call, every estimate, every repair completion — even for issues you think are minor.
8. What Conditions Trigger the Warranty: The Statutory List (C.R.S. § 38-12-505)
Regular uninhabitable conditions include but are not limited to: mold that materially interferes with the health or safety of the tenant; a substantial lack of functioning appliances; plumbing or gas facilities that are not maintained in good working order; electrical lighting and electrical equipment that are not maintained in good working order; or general violations of applicable building, housing, and health codes (C.R.S. § 38-12-505(1)(b)).
On top of this baseline list, a rebuttable presumption arises that certain conditions constitute habitability violations — including poor weatherproofing; unsafe gas utility conditions; inadequate running water; inadequate heat October through April; electrical conditions; lack of electricity; plumbing problems; inaccessible fire exits; problems with chimneys/vents; and elevator problems and accessibility issues for disabled tenants (C.R.S. § 38-12-505(4)). A landlord may rebut the presumption that these conditions are habitability violations by demonstrating that they do not materially interfere with life, health, or safety. That rebuttal standard is high — Colorado courts must "broadly interpret" the habitability statutes under C.R.S. § 38-12-501.
Two additions from the 2024 overhaul deserve special attention. First, failure to disclose radon per statute is now a per se breach of the warranty of habitability under C.R.S. § 38-12-503(2.4). Second, SB24-094 added extreme heat events to the habitability framework: the statute addresses interior temperatures not higher than eighty degrees Fahrenheit during declared heat events, which can require landlords to supply portable cooling devices where air conditioning isn't available.
8 (Continued). Temporary Housing Obligation: The 60-Day Rule
If the condition materially interferes with the tenant's life, health, or safety, remedial action must include a landlord providing the tenant, at the request of the tenant and within twenty-four hours after the tenant's request: (A) a comparable dwelling unit, as selected by the landlord, at no cost to the tenant; or (B) a hotel room, as selected by the landlord, at no cost to the tenant.
If a tenant requires a comparable dwelling unit or hotel room for more than forty-eight hours: (A) the comparable dwelling unit or hotel room must include a refrigerator with a freezer and a range stove or oven; or (B) the landlord must provide a per diem for daily meals and incidentals for each tenant in an amount that is at least equal to the Colorado state employee per diem for intrastate travel. The comparable unit must also be located within five miles of the tenant's unit unless the tenant consents to something farther.
When the displacement lasts beyond 60 days: if circumstances beyond the landlord's reasonable control cause the remediation to still not be done within 60 days, the landlord is relieved of the obligation to continue providing hotel accommodations upon notice to the tenant that the condition is no longer a material life/safety issue, the date the paid accommodations cease, and that the tenant may terminate the lease. Note: the tenant must continue paying rent as normal during any displacement period.
9. Tenant Remedies When You Breach (C.R.S. § 38-12-507)
A tenant who can establish a breach has multiple concurrent remedies. A tenant may terminate a rental agreement without any liability or financial penalty to the tenant if the condition that caused the breach remains unremedied or unrepaired, and the tenant provides the landlord ten to sixty days' written notice that states: (A) the uninhabitable condition or conditions that remain unremedied; (B) the tenant's intent to terminate the lease and vacate; and (C) the date upon which the tenant intends to terminate, which must be at least ten days after the date the notice is provided.
A tenant may deduct from one or more rent payments the cost of repairing or remedying a condition that is the basis of a breach of the warranty of habitability if: the tenant gives the landlord at least ten days' advance written notice of the tenant's intent to hire a licensed or otherwise qualified professional to remedy or repair the condition — except that the tenant may provide only forty-eight hours' advance written notice if the tenant has a good faith belief that the condition materially interferes with the tenant's life, health, or safety.
A tenant may also assert as a claim or counterclaim a landlord's breach of the warranty of habitability and may recover actual damages directly arising from the breach, which shall include any reduction in the fair rental value of the dwelling unit during any period that the residential premises were uninhabitable. A tenant may also recover court costs, reasonable attorney fees, punitive damages, and any other damages as ordered by the court. In a Forcible Entry and Detainer (eviction) case, a tenant can raise the breach as an affirmative defense — and the bond that was previously required to do so has been eliminated by SB24-094.
10. Anti-Retaliation: The Costliest Mistake (C.R.S. § 38-12-509)
A landlord shall not retaliate against a tenant in response to the tenant: (I) having made a good faith complaint to the landlord, to a nonprofit organization or third party, or to a governmental agency alleging a condition that materially interferes with the life, health, or safety of the tenant; (II) organizing or becoming a member of a tenants' association or similar organization; or (III) exercising or attempting to exercise in good faith any right or remedy afforded to a tenant pursuant to C.R.S. § 38-12-507.
The prohibited retaliatory actions are broad. Prohibited conduct includes terminating or not renewing a rental agreement or contract without written consent of the tenant; bringing or threatening to bring an action for possession; and taking action that in any manner intimidates, threatens, discriminates against, harasses, or retaliates against a tenant. There is now a legal definition of retaliation for non-renewal of a lease — meaning simply declining to renew a lease after a habitability complaint can constitute illegal retaliation.
The financial consequence is significant. If a landlord retaliates against a tenant in violation of C.R.S. § 38-12-509, the tenant shall recover damages in an amount not more than three months' periodic rent or three times the tenant's actual damages, whichever is greater, plus reasonable attorney fees and costs. The tenant's evidentiary burden is also lighter than many landlords expect: a tenant does not need to prove that retaliation was the sole reason a landlord engaged in adverse activity; a tenant need only demonstrate that the tenant's protected activity was a motivating factor that influenced the landlord's decision.
Common Landlord Mistakes Under Colorado's Habitability Law
Several patterns of landlord error show up repeatedly in habitability disputes, and being aware of them is often the difference between a resolved maintenance call and a court case.
Mistake 1: Starting but not finishing repairs. A breach also occurs when a landlord has commenced remedial action but failed to continue performing the remedial action as needed until the condition was remedied or repaired. Getting a contractor on-site once and then letting the job sit unfinished is still a breach.
Mistake 2: Thinking tenant-caused damage is always your defense. When a condition is substantially caused by the misconduct of the tenant, a member of the tenant's household, a guest or invitee of the tenant, or a person under the tenant's direction or control, the condition does not constitute a basis for a breach of the warranty of habitability. The operative word is "substantially." A landlord who contributed to the underlying condition through deferred maintenance can lose this defense even if the tenant made it worse.
Mistake 3: Ignoring the lease disclosure requirement. The bill went into effect on May 3, 2024, but the required disclosures for written lease agreements only affect leases formed on or after January 1, 2025. If you executed any new lease after January 1, 2025 without the bold 12-point disclosure and the reporting instructions, that lease is out of compliance right now.
Mistake 4: Assuming a tenant must report in writing. Under SB24-094, tenants can give notice of an uninhabitable condition verbally, by text, or through any other channel. If a tenant calls you about no heat on October 15 and you don't respond within 24 hours, your clock has already run — whether or not you received anything in writing.
Mistake 5: Filing an eviction immediately after a repair complaint. Under C.R.S. § 38-12-509, landlords are prohibited from retaliating against tenants who complain about habitability violations or contact government agencies. Colorado courts presume retaliation if adverse action occurs shortly after a tenant's protected activity. Even if the eviction is technically based on a lease violation, a judge can treat its timing as evidence of retaliation.

Get started →Frequently asked questions
Does Colorado's warranty of habitability apply even if my lease says the tenant takes the unit "as-is"?
Yes. The warranty of habitability under C.R.S. § 38-12-503 cannot be waived or contracted around. Any lease provision attempting to have a tenant accept the unit in a substandard condition, or to waive repair rights, is void as a matter of law. This is true whether the tenant has a written lease or a month-to-month oral agreement. The duty to provide and maintain a habitable unit runs for the entire tenancy, not just at move-in.
My tenant called me about a broken heater in November. How quickly do I legally have to respond in Colorado?
A heating failure that materially interferes with a tenant's life, health, or safety — which a broken heater in cold weather almost certainly does — triggers the 24-hour deadline under C.R.S. § 38-12-503(2)(b)(I)(A). That means you must begin remediation within 24 hours of receiving notice, not just return the call. The statute also requires you to continue making good faith efforts until the repair is complete. If you don't act within 24 to 96 hours, a rebuttable presumption of breach arises and the burden shifts to you to prove you responded adequately.
Can my Colorado tenant withhold rent because of a habitability problem?
Colorado tenants can deduct the cost of having a licensed professional make a repair from their rent, but only after giving the landlord at least 10 days' written notice of their intent to do so — or 48 hours' notice if the condition materially threatens life, health, or safety. The tenant cannot make the repair themselves and deduct the cost; a licensed or otherwise qualified contractor must do the work. If a court later finds the deduction was wrongful, you can recover the withheld amount. If the court finds the tenant acted in bad faith, you can recover double the amount wrongfully withheld under C.R.S. § 38-12-507.
What do I have to disclose about radon under Colorado law?
Under C.R.S. § 38-12-503(2.4) and § 38-12-803, failing to provide the required radon disclosure before a lease is signed is now a per se breach of the warranty of habitability. You must provide the statutory radon disclosure language, disclose any known radon levels and prior test results, describe any existing mitigation system, and give the tenant the radon brochure published by the Colorado Department of Public Health and Environment. If a test shows radon above the EPA action level and you don't remediate within 180 days, the tenant has the right to terminate the lease without penalty. Colorado has some of the highest naturally occurring radon levels in the country, so this disclosure requirement is particularly important here.
