Colorado Landlord-Tenant Laws: The Complete 2026 Overview

Colorado now caps the security deposit. Under section 38-12-102.5, effective in 2023, a landlord may not require deposits greater than two months’ rent, and that ceiling covers all deposits combined – so a separate pet or cleaning deposit cannot push the total above two months. On the way out, section 38-12-103 requires the landlord to return the deposit within one month after the tenancy ends by default, or up to sixty days only if the lease sets a longer period in advance, always with a written statement of the exact reasons for any deduction. The penalty for getting it wrong is severe: a willful failure to return or to itemize exposes the landlord to treble – three times – the amount wrongfully withheld, plus the tenant’s reasonable attorney fees, and the landlord bears the burden of proving the withholding was not wrongful. Money disputes go to small claims court.

Colorado evictions run through the forcible entry and detainer process in Title 13, Article 40. For nonpayment or a lease violation, the landlord must first serve a ten-day notice to pay or cure or quit. The larger change is just cause: since House Bill 24-1098 took effect in 2024, a landlord of most residential tenancies must have a statutory reason to evict or to decline to renew – nonpayment, a lease violation, or one of the listed no-fault grounds. If the tenant does not comply, the landlord files in County Court, where the tenant typically has seven days to respond and a hearing follows within roughly ten to thirty days. Self-help evictions – changing locks, removing doors, or shutting off utilities – are illegal, and only a sheriff or constable acting on a writ of possession may remove a tenant.

Colorado has no general statute setting a fixed notice period before a landlord enters an occupied unit. Instead, the lease and the tenant’s common-law covenant of quiet enjoyment govern, and the customary best practice is about twenty-four hours’ written notice for non-emergency entry during reasonable hours. The one place the legislature did set a rule is pest control: section 38-12-1004 requires advance notice before entering to inspect or treat for pests. Genuine emergencies such as fire, a burst pipe, or a gas leak permit immediate entry without notice. Because ordinary entry is governed by a standard rather than a bright-line statute, the single best way to avoid a dispute is to write the entry procedure – how much notice, by what method, and for what reasons – directly into the lease. A landlord who repeatedly enters without reasonable notice risks damages and, in severe cases, a claim for breach of quiet enjoyment.

Colorado has no rent control – there is no statewide cap on how much a landlord may raise the rent, and local rent control remains preempted by state law. What Colorado regulates is the process, and that tightened in 2024 under section 13-40-107. A landlord must give at least sixty days’ written notice before raising the rent on a month-to-month tenancy, and may raise the rent only once in any twelve-month period. During a fixed-term lease the rent is locked at the agreed figure, so an increase generally takes effect only at renewal or on a month-to-month tenancy unless the lease itself allows a mid-term change. The other limit is anti-retaliation: a landlord may not raise the rent to punish a tenant for a good-faith habitability complaint or for exercising a protected right, and doing so can trigger a statutory presumption of retaliation.

Colorado caps residential late fees by statute. Under section 38-12-105 a late fee may not exceed the greater of fifty dollars or five percent of the amount of rent past due, and it may be charged only after a seven-day grace period from the rent due date. The fee must be written into the lease to be enforceable, and a landlord may not remove a tenant, refuse to renew, or impose any other penalty solely because a late fee went unpaid. Daily or compounding late fees are allowed only if the lease provides for them and the total stays within the statutory ceiling. A returned-check or non-sufficient-funds fee is enforceable only when the lease sets it, and a reasonable figure is typically around twenty dollars. A fee that operates as a penalty rather than a reasonable charge – anything well above the statutory limit – is unenforceable and can be struck down in small claims court.

Colorado’s Warranty of Habitability Act, section 38-12-503, requires every residential landlord to keep the unit fit for human habitation, and the duty cannot be waived. The tenant triggers it with written notice – certified mail with a return receipt is best – and the landlord must then act fast: uninhabitable conditions and true emergencies such as gas leaks, no water, or sewage backups call for a response measured in as little as twenty-four hours, with other serious defects addressed within roughly twenty-four to ninety-six hours. Senate Bill 24-094 expanded tenant remedies in 2024, strengthening repair-and-deduct and other options where the landlord fails to act. Remedies can include lease termination, repair-and-deduct where authorized, rent damages, and injunctive relief. Retaliation against a tenant who asserts these rights is barred by section 38-12-509, so a landlord cannot answer a habitability complaint with a rent increase, a non-renewal, or an eviction.

Colorado codifies several protected reasons a tenant may end a fixed-term lease early without owing the full balance. A victim of domestic violence or abuse may terminate under section 38-12-402, with the tenant liable for at most one month’s rent, and only where the landlord documents the loss. Military servicemembers may terminate under the federal Servicemembers Civil Relief Act after delivering written notice and a copy of their orders, with the tenancy ending thirty days after the next rent is due. A tenant may also terminate when the landlord fails to fix a serious habitability defect after proper notice under sections 38-12-503 and 38-12-507. For a tenant who simply leaves without a statutory ground, Colorado follows the Schneiker v. Gordon duty to mitigate: the landlord must make a reasonable effort to re-rent, so the departing tenant owes only the vacancy gap until a reasonable re-rental, not the entire remaining term.

Ending a Colorado tenancy depends on its type, and the notice periods live in section 13-40-107. A month-to-month tenancy is terminated by written notice of at least twenty-one days from either party. For a fixed-term lease that the landlord chooses not to renew, the customary practice is to give notice well before the end date – often around ninety-one days out – and, since House Bill 24-1098, most non-renewals now require just cause rather than being at the landlord’s sole discretion. A fixed-term lease otherwise runs to its end date and cannot be cut short without a statutory ground or a mutual written agreement. A tenant who stays past the lease end date becomes a holdover, liable for rent and any damages through the holdover period, and the landlord must pursue possession through the eviction process rather than self-help. When any tenancy ends, the deposit rules of section 38-12-103 still govern the move-out.

For an actual pet, a Colorado landlord may set reasonable pet policies and charge a pet deposit or pet rent if the lease provides for it – but any pet deposit still counts toward the two-month combined deposit cap under section 38-12-102.5, so it cannot be stacked on top without limit. Assistance animals are treated completely differently. Under the federal Fair Housing Act, a service animal or emotional support animal is not a pet: a landlord may not charge any pet deposit, fee, or rent, and may not apply a breed, weight, or no-pet restriction to it. When the disability or the animal’s role is not obvious, the landlord may request reliable documentation from a licensed professional, but may not demand certification or registration. The tenant remains fully liable for any actual damage the animal causes, which the landlord may recover from the deposit or in a claim.

Colorado layers its own screening rules on top of the federal baseline. The binding federal law is the Fair Credit Reporting Act: with the applicant’s written authorization, a landlord may pull a consumer report covering credit, rental history, income, and criminal records, and must have a permissible purpose and consent first. On top of that, section 38-12-902 and the Colorado Consumer Credit Reporting framework require written consent, direct that a portable screening report be accepted so an applicant need not pay for a fresh report every time, and limit the consumer-report lookback to a seven-year window. Colorado sets no explicit dollar cap on the screening fee, but it should be reasonable and tied to the actual cost. If a denial, a higher deposit, or a co-signer requirement rests in any part on a consumer report, the FCRA requires an adverse action notice naming the reporting agency, and a violation can expose the user to up to one thousand dollars per violation plus actual damages and attorney fees.
