Colorado Landlord-Tenant Laws: What Renters Need to Know

1. Overview: Colorado’s Landlord-Tenant Laws

Colorado’s landlord-tenant relationship is governed by several statutes scattered across C.R.S. Title 38, Article 12 (Tenants and Landlords). Unlike states that bundle everything into one tidy act, Colorado’s rules live in multiple parts: security deposits in Part 1, the warranty of habitability in Part 5, and eviction procedures in Part 7 (among others).

Colorado has shifted significantly toward tenant protections in recent years. The state passed a just cause eviction law in 2024 (HB24-1098), expanded the warranty of habitability, capped late fees, required a seven-day grace period before late fees can kick in, and in 2026, tightened security deposit rules and banned many so-called “junk fees.” The result is a state that looks very different from a decade ago — landlords still have plenty of rights, but tenants now have real tools to push back.

These laws apply to most residential rentals. Some provisions have exemptions for owner-occupied duplexes and triplexes, short-term rentals, and employer-provided housing. Commercial leases and agricultural land are governed by different rules.

2. Security Deposit Rules

Security deposit fights are the bread and butter of landlord-tenant disputes in Colorado. The rules changed meaningfully on January 1, 2026, under HB25-1249. Here’s exactly how the law works now.

Deposit Limits

Colorado has no statutory cap on security deposit amounts. Your landlord can charge whatever they want. Most landlords charge one to two months’ rent, but there’s no law preventing them from asking for more. If the number feels unreasonable, negotiate before you sign.

Return Deadline

Under C.R.S. 38-12-103, your landlord has 30 days after the tenancy ends or you surrender the premises (whichever comes last) to return your deposit. The lease can extend this to up to 60 days, but no longer. If your lease says 90 days, that clause is unenforceable — the maximum is 60.

Itemization Requirement

If your landlord keeps any portion of the deposit, they must provide a written itemized statementlisting the exact reasons for each deduction, along with any remaining balance. Under HB25-1249, this statement can be mailed to your last known address or emailed if the landlord has your email address. A vague line like “cleaning and damages: $600” won’t cut it — you’re entitled to specifics.

Penalty for Non-Compliance

Colorado law has real teeth here. If your landlord wrongfully withholds your deposit or fails to provide a proper itemization, you can recover three times the amount wrongfully withheld plus reasonable attorney’s fees and costs. That’s treble damages. If your landlord kept $800 without justification, you could recover $2,400 plus legal costs.

What They Can (and Can’t) Deduct — 2026 Updates

Your landlord can deduct for unpaid rent and for damages beyond normal wear and tear. Starting January 1, 2026, HB25-1249 expanded the definition of “normal wear and tear” in three significant ways:

• Cleaning: General dirtiness is now considered wear and tear. Your landlord can only deduct for cleaning if the unit is “substantially less clean” than when you moved in
• Carpet: Landlords can only charge for carpet replacement if there’s major, irreparable damage that goes beyond normal wear
• Paint: Minor scuffs and fading from normal use are wear and tear, not deductible damage

Actual damage — holes in walls, broken fixtures, pet stains, burn marks — remains fair game for deductions.

3. Eviction Procedures and Notice Requirements

Colorado overhauled its eviction rules in 2024 with the passage of HB24-1098, the state’s just cause eviction law. Your landlord can no longer simply let your lease expire and refuse to renew without a reason. Here’s how evictions work now.

Just Cause Requirement

Under HB24-1098, landlords must have a legally valid reason — called “cause” — to evict a residential tenant. This applies to tenants who have lived in the unit for 12 months or more. Tenants under 12 months, short-term rentals, owner-occupied duplexes and triplexes, and employer-provided housing are exempt from the just cause requirement.

Notice for Unpaid Rent

If you don’t pay rent, your landlord must give you a 10-day written notice to pay or vacate. This was increased from the old 3-day notice under HB24-1098. If you pay the full amount within those 10 days, the eviction process stops. For properties with federal subsidies or federally backed mortgages, the notice period may be 30 days.

Notice for Lease Violations

For your first material lease violation — unauthorized pets, noise complaints, unauthorized occupants — your landlord must give you a 10-day written notice (called a “Demand for Compliance or Possession”) describing the specific violation and giving you 10 days to fix it or move out. If you cure the problem within that window, the lease continues.

Substantial Violations

For serious issues involving safety or criminal activity, Colorado allows a shorter 3-day notice. A “substantial violation” means conduct by the tenant or their guest that:

• Endangers a person or property on or near the rental
• Involves a violent or drug-related felony on or near the rental
• Constitutes a criminal act carrying a possible prison sentence of at least 180 days and qualifies as a public nuisance

No-Fault Eviction Grounds

Even under the just cause law, landlords can still evict for certain no-fault reasons — but they must give 90 days’ notice. Valid no-fault grounds include:

• Demolition or conversion of the property
• Substantial renovations that require the unit to be vacant
• The landlord or a family member moving into the unit
• Withdrawing the unit from the rental market to sell it

Illegal Self-Help Evictions

Changing the locks, shutting off utilities, removing your belongings, or physically blocking you from your unit is illegal in Colorado. Only a court order can force you out, and only a sheriff can carry it out. If your landlord tries a self-help eviction, you have legal remedies including damages and attorney’s fees.

4. Landlord Entry and Notice Rules

Your landlord owns the building, but you’re paying for the right to live there. Colorado law protects your privacy with clear rules about when and how a landlord can enter.

24-Hour Notice Requirement

Under C.R.S. 38-12-503, your landlord must give you at least 24 hours’ written notice before entering your unit for repairs or maintenance. Entry must be at a reasonable time. You can reasonably deny entry at the proposed date and time — but you must suggest an alternative that works.

Exceptions

• Emergencies: Your landlord can enter without notice when a condition materially and imminently threatens someone’s life, health, or safety, or when immediate action is needed to prevent substantial property damage
• Bed bug inspections: The landlord must give at least 48 hours’written or electronic notice before entering for bed bug inspections

Tenant’s Right to Deny Entry

Here’s something many tenants don’t realize: you can reasonably deny entry at the specific date and time your landlord proposes. The landlord must then suggest a new time, and you can accept or counter-propose. You also have the option to let the landlord in with less than 24 hours’ notice if you choose to — but it’s your choice, not theirs.

5. Habitability Standards and Repairs

Colorado has one of the stronger warranty of habitability laws in the country. It’s codified at C.R.S. 38-12-503 through 38-12-512, and landlords cannot waive it. Any lease clause that tries to is void as contrary to public policy.

What Your Landlord Must Provide

Under C.R.S. 38-12-503, your landlord must maintain the premises in a habitable condition at their own expense. The warranty covers conditions that materially interfere with your life, health, or safety, including:

• Waterproofing and weather protection of roof and exterior walls
• Plumbing in good working order, with hot and cold running water
• Heating facilities in good working order
• Electrical lighting and wiring maintained in good working order
• Common areas kept clean, sanitary, and free from hazards
• Adequate trash receptacles
• Working locks and security devices
• Compliance with applicable building and housing codes

Repair Timelines

Colorado sets strict deadlines for landlords to begin repairs:

• 24 hours when the condition materially interferes with life, health, or safety
• 72 hours when the premises are uninhabitable

These timelines are for commencing repair, not completing it. But the landlord has to demonstrate real progress. If they don’t start within the required window, they’ve breached the warranty.

Your Remedies

Under C.R.S. 38-12-507, if your landlord breaches the warranty of habitability, you have several powerful options:

• Terminate the lease without penalty by giving 10 to 60 days’ written notice (depending on severity)
• Deduct repair costs from rent if you give at least 10 days’ advance written notice (or 48 hours for life/health/safety issues) and the landlord fails to fix the problem
• Recover damages in court
• Seek injunctive relief to force repairs

One caveat: these remedies don’t apply if you or someone you let into the unit caused the problem.

6. Rent Payment Rules

When Is Rent Due?

Rent is due on the date specified in your lease. If your lease doesn’t specify, rent is typically payable at the beginning of each rental period. Most leases set the first of the month as the due date.

Grace Periods

Colorado law requires a seven-day grace period before a landlord can charge late fees. Your landlord cannot hit you with a late fee until at least seven days after the rent due date. This is a state-mandated minimum — your lease can offer a longer grace period, but it can’t shorten this one.

Late Fees

Under C.R.S. 38-12-105, Colorado caps late fees at the greater of $50 or 5% of the past-due rent. Your landlord can only charge a late fee once per late payment, even if the balance remains overdue for weeks. And the late fee must be clearly stated in your lease to be enforceable. If your lease doesn’t mention late fees, your landlord can’t charge one.

Junk Fee Protections (2026)

Starting January 1, 2026, under HB25-1090, Colorado banned many hidden charges in rental transactions. Landlords must now:

• Disclose the total price of rent upfront, including all mandatory fees
• Not charge tenants more for utilities than the amount billed by the utility provider
• Limit non-utility fee increases to no more than 2% during lease terms of one year or less
• Cap markups on third-party services (trash, internet, pest control) at 2% or $10/month, whichever is less

7. Lease Termination and Breaking a Lease

Ending a Periodic Tenancy

Colorado’s notice requirements for ending a month-to-month tenancy depend on how long you’ve lived there:

• Less than 6 months: At least 21 days’ written notice
• 6 to 12 months: At least 28 days’ written notice
• 1 year or more: At least 91 days’ written notice, and the landlord must have just cause to terminate

Breaking a Fixed-Term Lease

If you’re on a 12-month lease and need to leave early, you’re generally on the hook for the remaining rent. But Colorado law recognizes several legitimate reasons for early termination:

• Breach of warranty of habitability: If the unit is uninhabitable and your landlord won’t fix it after proper notice (C.R.S. 38-12-507)
• Illegal lockout or utility shutoff: Self-help eviction by the landlord
• Domestic violence, sexual assault, or stalking: Colorado allows victims to terminate early with proper documentation
• Military deployment: Under the federal Servicemembers Civil Relief Act (50 U.S.C. §§ 3901–4043)

Landlord’s Duty to Re-Rent

If you do break a lease, your landlord must make reasonable efforts to re-rent the unit. You’re only liable for rent until a new tenant moves in. Your landlord can’t just leave the unit empty and send you the bill for the entire remaining lease term.

8. Retaliation Protections

Colorado’s anti-retaliation protections are strong and well-defined. Many tenants don’t know about them, which is a shame — they’re one of your most powerful tools.

Under C.R.S. 38-12-509, your landlord cannot retaliate against you for:

• Making a good-faith complaint to the landlord, a nonprofit, a third party, or a government agency about conditions that materially interfere with your life, health, or safety
• Organizing or joining a tenants’ association
• Exercising your rights under the warranty of habitability (C.R.S. 38-12-507)

What Counts as Retaliation

Prohibited retaliatory actions include terminating or refusing to renew your lease, filing or threatening eviction, raising rent, decreasing services, and any action that intimidates, threatens, discriminates against, harasses, or retaliates against you.

Burden of Proof

Here’s what makes Colorado’s law particularly tenant-friendly: you don’t have to prove retaliation was the sole reason for your landlord’s action. You only need to show that your protected activity was a motivating factor. That’s a much lower bar to clear.

What You Can Recover

If your landlord retaliates, you can use it as a defense in any eviction action. You can also recover up to three months’ periodic rent or three times your actual damages, whichever is greater, plus reasonable attorney’s fees and costs.

9. Fair Housing Protections

Colorado’s fair housing protections go well beyond federal law. If you’ve been discriminated against in housing, Colorado gives you more categories to file under and more agencies to file with.

Colorado Anti-Discrimination Act (CADA)

The Colorado Anti-Discrimination Act prohibits housing discrimination based on:

• Race
• Color
• Religion / Creed
• Sex
• National origin
• Ancestry
• Disability
• Familial status (having children under 18)
• Sexual orientation (including gender identity)
• Marital status
• Veteran or military status
• Source of income (e.g., housing vouchers)

That last one matters a lot: Colorado landlords cannot refuse to rent to you because you pay with a Housing Choice Voucher (Section 8) or another lawful source of income. Many states don’t have this protection.

Where to File a Complaint

The Colorado Civil Rights Division (CCRD) enforces the state’s fair housing law. You must file a complaint within one year of the discriminatory act. You can file online at ccrd.colorado.gov.

Federal Protections

The federal Fair Housing Act (42 U.S.C. §§ 3601–3619) provides baseline protections and is enforced by HUD. You can file a federal complaint with HUD’s Office of Fair Housing and Equal Opportunity within one year of the discriminatory act.

Broader Coverage Than Federal Law

Unlike the federal Fair Housing Act, Colorado’s law applies to all housing — including owner-occupied buildings with fewer than four units, which are partially exempt under federal law. Colorado also covers more protected classes than the federal baseline, including sexual orientation, gender identity, marital status, veteran status, and source of income.

10. Rent Control Status

Colorado has no rent control. There is no state law limiting how much a landlord can raise your rent.

Colorado also preempts local rent control — cities and counties cannot pass their own rent control ordinances. A municipality in Colorado cannot cap or limit the amount of rent a landlord charges for private residential property.

For month-to-month tenancies, your landlord must give advance written notice before raising rent — typically at least 21 days for tenancies under six months, and 28 days for tenancies of six to twelve months. During a fixed-term lease, your rent cannot increase unless the lease includes a rent escalation clause.

11. Small Claims Court

Colorado’s small claims courts are a practical option for most landlord-tenant disputes.

• Maximum claim amount: $7,500 (not including interest or costs)
• Where to file: The county court where the rental property is located
• Attorney optional: You can represent yourself
• Filing fees: $31 for claims up to $500; $55 for claims up to $7,500

If your dispute is over $7,500 but under $25,000, you can still file in county court (not small claims). For security deposit disputes, small claims court is usually the fastest route. Bring your lease, move-in and move-out photos, copies of correspondence with your landlord, and the itemized deduction statement (or evidence that one was never provided). Given the treble damages provision in C.R.S. 38-12-103, even a modest deposit dispute can be worth pursuing.
