Colorado Landlord-Tenant Laws (2026): Deposits, Notice, and Tenant Rights

Colorado landlords may hold a maximum security deposit of two months' rent under C.R.S. 38-12-102.5, and must return it within 30 days of move-out unless the lease specifies a longer period of up to 60 days. The state does not set a fixed minimum notice-to-enter period for routine entry, but 24 to 48 hours is the well-established standard.

Security deposits in Colorado

Colorado caps security deposits by statute. Under C.R.S. 38-12-102.5, a landlord may not require a tenant to submit a security deposit in an amount that exceeds two monthly rent payments under the rental agreement. That cap has been in force since August 7, 2023, when SB 23-184 took effect, and it applies regardless of lease length or unit type.

The rules for getting the deposit back did change on January 1, 2026, when HB 25-1249 took effect. The return deadline is now stated as 30 days rather than one month, a landlord must hand over supporting documentation such as photographs, inspection forms, receipts, invoices, or estimates within 14 days of a written tenant request, and a tenant may ask for a walk-through inspection before move-out to identify damage in writing. HB 25-1249 did not change the deposit cap and did not create any right to pay a deposit in installments. Even so, it is one of the more significant recent changes to Colorado tenant rights.

The deposit must be returned, together with a written itemized accounting of any deductions, within 30 days of the lease terminating or the tenant surrendering the premises, whichever happens last. A lease may specify a longer period, but not more than 60 days. Allowable deductions cover unpaid rent and damage beyond normal wear and tear; a landlord may not retain the deposit for normal wear and tear or for a defective condition that preexisted the tenancy. If the landlord wrongfully withholds the deposit, the tenant may recover treble the wrongfully withheld amount plus reasonable attorney fees and court costs under C.R.S. 38-12-103, but the tenant must first give the landlord written notice of the demand and of the intent to file suit at least seven days before filing.

When can a landlord enter? Notice rules

Colorado does not have a single statewide statute setting a fixed minimum advance notice period for all types of routine landlord entry. In practice, courts and housing agencies recognize 24 to 48 hours as the appropriate advance notice standard, and this is frequently written into lease agreements. For bed-bug inspections specifically, state law requires 48 hours' written notice.

Landlords may enter for legitimate purposes: repairs, inspections, showing the unit to prospective tenants or buyers, and similar needs. Entry must occur at reasonable hours, generally understood as normal daytime and early evening hours. In genuine emergencies involving immediate threats to person or property, a landlord may enter without advance notice. Many leases in Colorado specify a 24-hour or 48-hour notice requirement; those lease provisions are enforceable and represent the clearest standard for most tenants.

If a landlord repeatedly enters without proper notice or at unreasonable hours, that conduct can amount to harassment. Colorado courts have found that systematic violations of tenant privacy can support a claim for damages and, in extreme cases, grounds for constructive eviction.

Ending a lease: notice to vacate

Colorado no longer lets a landlord end most residential tenancies simply by giving notice. Under C.R.S. 38-12-1303, added by HB 24-1098 in 2024, a landlord may not serve a notice to terminate tenancy, make a demand for possession, or proceed with an eviction action unless there is cause. That requirement reaches every residential premises in the state except the categories listed in C.R.S. 38-12-1302: short-term rentals, owner-occupied single-family homes, duplexes and triplexes, mobile-home spaces held under a lease-to-own or purchase-option agreement, employer-provided housing, tenancies that have run less than 12 months, and occupants the landlord does not know to be tenants.

Where the cause requirement applies and there is no lease violation to point to, a landlord must fit one of six no-fault grounds in C.R.S. 38-12-1303(3): demolition or conversion of the premises, substantial repairs or renovations, the landlord or a family member of the landlord moving in, withdrawal from the rental market in order to sell, the tenant's refusal to sign a new lease with reasonable terms, or a history of nonpayment of rent. Each of those requires at least 90 days written notice that states the legal and factual basis for the eviction. A landlord who is on active military duty, or who is the spouse of such a person, may give 45 days notice instead.

Tenants, and landlords of the exempt property types listed above, terminate under C.R.S. 13-40-107 instead, which scales the notice to the length of the tenancy rather than fixing it at 30 days. That statute requires at least 91 days for a tenancy of one year or longer, 28 days for a tenancy of six months or longer but less than a year, 21 days for a tenancy of one month or longer but less than six months, 3 days for a tenancy of one week or longer but less than one month or a tenancy at will, and 1 day for a tenancy of less than a week. No written notice is needed from a tenant whose fixed-term lease is, by agreement, set to end on a certain date.

For terminations based on nonpayment of rent, a lease violation, or other for-cause grounds, a separate formal notice process applies under Colorado eviction law. See the Colorado eviction notice generator for the specific notice forms and timelines required for each type of eviction. For holdover tenants or squatters, see Colorado squatters rights.

Repairs and the warranty of habitability

Colorado's warranty of habitability is codified at C.R.S. 38-12-503 and covers all residential rental units in the state. Landlords must maintain the unit in a condition that is fit for human habitation, which includes working heating, plumbing, electrical systems, weatherproofing, and freedom from conditions that pose a material health or safety threat. The standard requires that the unit meet local building and housing codes to the extent those codes affect habitability.

Colorado tenants do have a repair-and-deduct remedy, but it lives in C.R.S. 38-12-507(1)(c), the tenant-remedies section, rather than in the warranty section itself. The tenant must give the landlord at least 10 days advance written notice of an intent to hire a licensed or otherwise qualified professional to fix the condition. Only 48 hours notice is required if the tenant has a good-faith belief that the condition materially interferes with the tenant's life, health, or safety. If the landlord fails to sufficiently repair the condition within that window, the tenant may deduct the cost from one or more rent payments.

The statute attaches conditions that decide whether the deduction is lawful, and they are easy to miss. The professional must not be a relative of the tenant and must provide an estimate reasonably consistent with industry standards; the tenant must actually hire that professional rather than doing the work personally; and the tenant must give the landlord a receipt, invoice, or proof of payment within a reasonable time after the work is finished or within 30 days after the landlord requests it. A tenant who deducts without substantially complying can be sued, and a court that finds the deduction was made in bad faith must award the landlord double the amount unlawfully deducted. A separate provision at C.R.S. 38-12-507(1)(c)(II) lets a tenant replace a broken or malfunctioning appliance on 3 days notice. Tenants should always send repair requests in writing, keep copies, and retain receipts for any work performed.

In addition to repair-and-deduct, tenants facing persistent habitability failures may pursue rent reduction, seek an order from a housing court, or in serious cases, treat the landlord's failure as a constructive eviction and terminate the lease.

Rent, late fees, and rent control

Colorado sets firm, clear rules on late fees. Before a landlord may charge any late fee at all, the tenant must be at least 7 calendar days late with rent payment. That 7-day grace period is mandatory and may not be shortened by lease language. After the grace period expires, the late fee may not exceed the greater of $50 or 5% of the past due rent payment, and the fee has to be disclosed in the rental agreement before it can be charged at all. A lease provision that does not comply with C.R.S. 38-12-105 is void and unenforceable.

Rent control is preempted by state law in Colorado. Cities and counties may not enact rent stabilization ordinances or set any cap on the amount landlords may charge or increase rent in the private market. The sole exception is voluntary deed-restricted affordable housing, where below-market rents are part of a regulatory agreement rather than a municipal mandate.

Colorado does not cap the size of a rent increase, but it does limit how often one may come. Under C.R.S. 38-12-702, a landlord may not increase rent more than one time in any twelve-month period of consecutive occupancy by the tenant, regardless of whether there is a written rental agreement, how long the tenancy has run, or whether the tenancy is fixed-term, month-to-month, or indefinite. That is the one statewide constraint on rent increases in Colorado.

Notice of an increase is governed by C.R.S. 38-12-701. In a residential tenancy in which there is no written agreement between the landlord and tenant, a landlord may increase the rent only upon at least 60 days written notice, and may not terminate such a tenancy with the primary purpose of raising rent in a way that sidesteps that notice. Where there is a written lease, the lease's own terms and renewal schedule control when an increase can take effect.

If you have a landlord-tenant dispute in Colorado

Start by creating a clear paper trail. Send all communications to your landlord in writing, preferably by certified mail or email with read receipts. Photograph any habitability issues with a date stamp as soon as they appear. For repair requests, keep a copy of every notice you send and note the date you sent it.

For security deposit disputes, Colorado small claims court handles cases up to $7,500 and is an accessible, lower-cost venue. Under C.R.S. 38-12-103, a landlord who wrongfully withholds a deposit past the deadline may owe treble the withheld amount plus reasonable attorney fees and court costs, though the tenant must first send a written demand and notice of intent to sue at least seven days before filing. Bring your lease, move-in and move-out checklists, photographs, and any written correspondence to court.

For habitability issues, contact your city or county code-enforcement department to request an inspection. A code-inspection report creates official documentation that significantly strengthens a repair-and-deduct or rent-reduction claim. The Colorado Department of Local Affairs and the Colorado Attorney General's office maintain tenant-rights resources and complaint processes.

If your dispute involves eviction, substantial damages, or a potential wrongful eviction claim, consulting a tenant-rights attorney is worthwhile. Colorado Legal Services provides free civil legal assistance to qualifying low-income residents throughout the state.
