Colorado Landlord Laws: Deposits, Habitability, and Evictions

Colorado landlord laws come primarily from the Colorado Residential Landlord and Tenant Act, and they set a floor that no lease can drop below. They govern how security deposits are held and returned, what makes a unit habitable, how fast a landlord must respond to repair requests, when late fees can be charged, how eviction notices must be served, and which classes of tenants get extra protection. The penalties for getting these wrong can reach triple damages and attorney fees, so the details matter.

Security Deposits

There is no statutory cap on how much a Colorado landlord can collect as a security deposit. The tight rules are on the back end. After the lease ends or the tenant surrenders the unit (whichever is later), the landlord has one month to return the full deposit or send a written statement itemizing every deduction. A lease can stretch that window to a maximum of 60 days, but no longer.¹

Deductions are limited to actual losses: unpaid rent, damage beyond normal wear and tear, or costs tied to abandonment. Normal wear and tear is the deterioration that happens through everyday use, like faded paint, minor floor scuffs, or aging carpet. Landlords cannot charge for it.

The penalties are steep on purpose. A court can award a tenant triple the wrongfully withheld amount plus reasonable attorney fees and court costs when a landlord willfully withholds a deposit in violation of the statute.¹ If the tenant never receives either the deposit or an itemized statement within the required window, the retention is automatically deemed willful, and the tenant is entitled to twice the full deposit plus attorney fees.²

Habitability and Repair Obligations

Every residential lease in Colorado carries an implied warranty of habitability. The landlord must deliver a unit fit for human habitation and keep it that way throughout the tenancy.³ The warranty cannot be waived by lease.

A unit is uninhabitable if it substantially lacks any of the following:⁴

Working heat that was code-compliant when installed
Hot and cold running water and connection to approved sewage
Weatherproofing (roof, exterior walls, windows, doors)
Functioning electrical wiring and equipment
Working landlord-supplied appliances
Extermination of rodents, vermin, and insects
Clean, sanitary common areas
Locks on exterior doors and security devices on openable windows
Sound floors, stairways, elevators, and railings

Mold associated with dampness also makes a unit uninhabitable, unless it’s the minor kind that naturally appears on surfaces designed for moisture, like bathroom tile.⁴

Response Deadlines

The tenant sends the landlord reasonably complete written or electronic notice describing the condition. The clock starts when the landlord receives it. Deadlines to begin remedial action depend on severity:

24 hours for conditions materially interfering with life, health, or safety (gas leak, no heat in winter, raw sewage backup)
72 hours for conditions that make the unit uninhabitable but don’t pose an immediate threat³

These deadlines require the landlord to start work, not to finish. If the condition still exists 7 calendar days after notice for life-safety issues, or 14 days after notice for other uninhabitable conditions, there is a rebuttable presumption that the landlord failed to act.³

When the landlord fails to respond in a reasonable time, the tenant can terminate the lease on 10 to 60 days’ written notice (or 10 days if the same condition returns within six months of an earlier repair), hire a licensed professional to fix the problem and deduct the cost from rent after giving the landlord 10 days’ written notice (48 hours for life-threatening conditions), sue for damages and attorney fees, or ask a court for injunctive relief.

Late Fees

A late fee cannot be assessed until rent is at least seven calendar days overdue, and the fee is capped at the greater of $50 or 5% of the past-due amount.⁵ On $1,500 rent, that maximum is $75.

Late fees are legally separate from rent. A lease cannot reclassify a late fee as rent, and no tenant can be evicted for failing to pay one.⁵

Eviction Notices

A landlord cannot go straight to court. Written notice with a mandatory waiting period comes first.

Nonpayment and Lease Violations

For unpaid rent or a material lease violation, the landlord must serve a written 10-day notice demanding payment or compliance, or possession. The tenant has the full 10 days to cure. Pay the rent or fix the violation in that window, and the eviction cannot go forward.⁶ A residential lease cannot shorten this period. The notice must be in writing, identify the specific breach or exact amount owed, and be either personally delivered or posted conspicuously on the property.

No-Fault Terminations

Colorado’s just cause eviction law generally requires at least 90 days’ written notice for a no-fault termination on covered residential properties, and may require a qualifying reason rather than a simple non-renewal.

Properties exempt from the just cause statute (including certain owner-occupied buildings and single-family homes where the owner has only one rental) fall under a separate tiered notice statute, keyed to tenancy length:⁷

One year or longer: at least 91 days
Six months to under one year: at least 28 days
One month to under six months: at least 21 days
One week to under one month, or tenancy at will: at least 3 days
Less than one week: at least 1 day

The written notice must describe the property, state the termination date, and be signed by the landlord or the landlord’s agent.

Entering the Rental Unit

Colorado has no single general statute setting a specific number of hours’ notice for landlord entry. Entry rules come from specific statutes, the lease, and the implied covenant of quiet enjoyment.

The clearest statutory rule is for bed bug inspection or treatment: the landlord must give at least 48 hours’ reasonable written or electronic notice, unless the lease sets a different minimum.⁸ For other non-emergency entry, courts and well-drafted leases follow a reasonable-notice standard, commonly 24 hours or more, for routine inspections and maintenance.

Genuine emergencies are the exception. A burst pipe, gas leak, or fire justifies immediate entry. Outside of that, entering without proper justification exposes the landlord to a trespass or lease-breach claim.

Retaliation

A landlord cannot punish a tenant for exercising legal rights. Protected activity includes filing a good-faith habitability complaint (with the landlord, a government agency, or a nonprofit), joining a tenants’ association, or pursuing any remedy the habitability statutes provide.⁹

Prohibited retaliation includes raising rent, reducing services, threatening eviction, filing a possession action, or adding new fees in response to protected activity. The tenant does not need to prove retaliation was the only motive; showing the protected activity was a motivating factor is enough.⁹ Timing matters. A rent hike two weeks after a habitability complaint invites scrutiny that is hard to survive in court.

Fair Housing and Discrimination

The federal Fair Housing Act bars discrimination based on race, color, religion, national origin, sex, familial status, and disability.¹⁰ Colorado adds ancestry, creed, marital status, sexual orientation (which under Colorado law includes transgender status), source of income, and veteran or military status.¹¹

For tenants with disabilities, landlords must grant reasonable accommodations (such as allowing a service animal despite a no-pets policy) and permit reasonable modifications (such as installing a grab bar). The source-of-income protection prevents refusing tenants solely because they pay with housing vouchers or other public assistance. Complaints go to the Colorado Civil Rights Division or the U.S. Department of Housing and Urban Development.

Domestic Violence Victims

A tenant who is the victim of domestic violence, domestic abuse, unlawful sexual behavior, or stalking can terminate a lease early without the usual penalties. The tenant must give the landlord written notice along with a police report filed within the prior 60 days or a valid protection order.¹²

The tenant owes one month’s rent after vacating, payable within 90 days, and only if the landlord has documented damages of at least a month’s rent from the early termination. The landlord must keep the tenant’s victim status confidential and cannot share the tenant’s new address without consent.¹² Leases cannot penalize a tenant for calling police or emergency services in a domestic violence situation, and a tenant cannot be evicted solely for being a victim.

Military Servicemembers

The federal Servicemembers Civil Relief Act lets an active-duty servicemember end a residential lease early after receiving orders for a permanent change of station or a deployment of at least 90 days. This is a statutory right, not a breach, so no early termination or concession recapture fees apply.¹³

The servicemember delivers written notice with a copy of the orders, by hand, private carrier, or U.S. mail with return receipt. On a monthly lease, termination takes effect 30 days after the next rent date following delivery. Prorated rent is still owed through the termination date, and the landlord can still make legitimate deductions from the deposit for damage beyond normal wear and tear. Rent paid in advance for periods after the termination date must be refunded within 30 days.¹³ Dependents are covered too.

Lead Paint Disclosure for Pre-1978 Rentals

Federal law requires landlords of any housing built before 1978 to do three things before the tenant signs: disclose any known lead-based paint or lead hazards, provide any available lead inspection reports, and give the tenant a copy of the EPA pamphlet “Protect Your Family from Lead in Your Home.”¹⁰

A knowing violation carries civil penalties of up to $10,000 per violation, and the landlord can be liable for triple the tenant’s actual damages plus court costs and attorney fees. The rule reaches every Colorado rental built before 1978, from a single-family house to a large apartment complex.
