colorado landlord tenant law and unpaid rent

Key Takeaways

Colorado rental laws shape nearly every stage of the landlord tenant relationship, from applicant screening and lease terms to maintenance, deposits, and ending a tenancy.
Clear records, consistent screening standards, and timely compliance can help Denver rental owners reduce disputes and protect the long term performance of their investments.
Because state requirements can change, property owners should regularly review their leases, notices, and management procedures rather than relying on older practices.

As parties to the Colorado lease or rental agreement, both the landlord and the tenant are required to adhere to the Colorado landlord-tenant law. The landlord tenant law states the rights and landlord tenant responsibilities, among other things.

Failure by one party to adhere to the terms means the aggrieved party has a right to seek legal redress. If you are a tenant or landlord seeking to learn more about the Colorado landlord-tenant law, here’s an overview to get you started.

Required Landlord Disclosures in Colorado

As a landlord, you owe your tenants certain information and disclosures before they sign a lease agreement. Colorado law requires landlords to provide certain information to prospective tenants, while other disclosures may apply depending on the property or circumstances. The following are some of the key disclosures and information landlords should be aware of when renting out residential property in Colorado:

Lead Paint Disclosure. Federal law requires landlords of most housing built before 1978 to disclose known lead-based paint and lead-based paint hazards before a tenant signs a lease. Landlords must also provide the federally approved lead-hazard information pamphlet and include the required lead warning language in the lease or an attachment. Colorado’s Division of Real Estate also provides a lead-based paint disclosure form for rental properties.
Radon Disclosure. Colorado law requires landlords to provide prospective tenants with written information about radon before they sign a residential lease. The disclosure must include a required warning statement, any known information about radon testing and concentrations at the property, information about any radon mitigation system, and the most recent Colorado Department of Public Health and Environment radon brochure. The tenant must sign the disclosure acknowledging receipt. Beginning January 1, 2026, the statutory remedy allowing a tenant to void a lease for failure to provide the radon disclosure or for failure to make a reasonable effort to mitigate elevated radon applies to leases longer than one year.
Landlord or Property Manager Information. A written Colorado rental agreement must identify the name and address of the landlord or the landlord’s authorized agent. If the landlord or authorized agent changes during the tenancy, the tenant must be notified in writing or electronically, or the new information must be posted in a conspicuous location on the property.
Warranty of Habitability Information. For rental agreements entered into on or after January 1, 2025, Colorado law requires a statement informing tenants of their right to safe and healthy housing and explaining that landlords cannot retaliate against tenants for reporting unsafe conditions, requesting repairs, or exercising their rights under the warranty of habitability. Rental agreements must also provide, in English and Spanish and in at least 12-point bold type, an address where tenants can mail or personally deliver written notice of an uninhabitable condition and an email address or accessible online portal where such notice can be submitted.
Source of Income Information. Certain written rental agreements must include a statement regarding Colorado’s prohibition on source-of-income discrimination. The requirement generally applies to landlords who are not exempt, with an exemption for landlords with five or fewer single-family rental homes and no more than five total rental units, including those single-family homes.
Utility Billing Method. Colorado’s 2026 utility-billing legislation allows landlords to use certain methods, including a ratio utility billing system, to allocate utility costs among tenants when specific requirements are met. When a landlord uses such a system, the method used to calculate the tenant’s utility charges must be clearly disclosed in the rental agreement.

Some disclosures listed in older versions of this article—such as structural damage, transportation projects, common interest communities, and special taxing districts—are not generally required statewide as pre-lease landlord-to-tenant disclosures. Some of these requirements apply to sellers and buyers during a residential real estate transaction instead. Landlords should still disclose any information specifically required by another applicable federal, state, or local law, as well as information required under the terms of the lease.

Colorado Tenant Responsibilities & Rights

The following are some of the basic rights and responsibilities of renters under Colorado landlord-tenant law. A tenant generally has the right to:

Live in a safe and habitable rental property. Colorado’s warranty of habitability requires landlords to maintain residential premises in a condition fit for human habitation. Depending on the circumstances, this includes requirements related to weatherproofing, plumbing, heating, electricity, sanitation, locks and security, and other health and safety conditions.
Receive the benefit of the rental agreement. Tenants have the right to occupy and use the property according to the terms of their lease, subject to applicable laws and reasonable lease provisions.
Receive reasonable notice before ordinary landlord entry. Colorado does not establish one general statewide number of hours that a landlord must provide before entering an occupied rental unit. Instead, entry is generally governed by the lease and the tenant’s right to privacy and quiet enjoyment. Landlords should provide reasonable notice and enter at reasonable times, except when an emergency or another specific legal exception applies. For bed-bug inspections or treatment, Colorado law generally requires at least 48 hours’ written or electronic notice before entry.
Have qualifying habitability problems addressed by the landlord. If a landlord receives proper notice of a condition that breaches the warranty of habitability, Colorado law provides specific procedures and deadlines for addressing the problem. Tenants may have remedies if the landlord fails to properly remedy a qualifying condition.
Use certain legal remedies when a landlord fails to maintain the property. Depending on the circumstances, a tenant may be able to terminate the lease, seek damages or other court remedies, or use Colorado’s statutory repair-and-deduct process. However, a tenant generally should not simply stop paying rent without following the specific legal requirements that apply to the situation.
Terminate a tenancy by providing the required notice. For periodic tenancies, Colorado generally requires written notice based on the length of the tenancy: 91 days for a tenancy of one year or longer, 28 days for a tenancy of six months or longer but less than one year, 21 days for a tenancy of one month or longer but less than six months, three days for a tenancy of one week or longer but less than one month or a tenancy at will, and one day for a tenancy of less than one week. A fixed-term tenancy that ends at a date certain generally does not require statutory notice from the tenant, although the lease may establish additional requirements.
End a lease early in certain legally protected circumstances. Colorado and federal law provide circumstances in which a tenant may have a right to terminate a lease early, including certain situations involving military service, domestic violence or abuse, stalking, or unlawful sexual behavior. These protections have specific eligibility and documentation requirements.
Remain in the property unless the landlord follows the legal eviction process. Colorado generally requires a landlord to have a legally recognized reason to remove a residential tenant and to follow the required notice and court procedures. Colorado’s 2024 just-cause law established protections against many no-cause evictions while identifying circumstances that may qualify as cause, including certain lease violations and specified no-fault situations.
Be free from unlawful retaliation and discrimination. Colorado law prohibits retaliation against tenants for exercising certain legal rights, including making good-faith complaints regarding unsafe or uninhabitable conditions. Landlords must also comply with applicable federal and Colorado fair housing laws.

Colorado landlord tenant rental agreements and eviction

Below are some of the basic responsibilities of renters under Colorado landlord-tenant law. A tenant generally has a responsibility to:

Follow the terms of the lease or rental agreement, including rules concerning rent, pets, property use, and other lawful lease requirements.
Pay rent on time and pay other charges that are lawfully assigned to the tenant under the rental agreement and applicable law.
Provide the landlord with required notice before moving out when the tenancy or lease requires notice. For periodic tenancies, the applicable statutory notice period depends on the length of the tenancy.
Take reasonable care of the rental property and avoid causing damage beyond normal wear and tear.
Notify the landlord promptly about maintenance and habitability problems. Tenants should provide the type of written or electronic notice required by the lease and Colorado law so the landlord has an opportunity to address the issue.
Allow lawful and reasonable access to the property. Tenants generally cannot unreasonably prevent a landlord, property manager, contractor, or other authorized person from accessing the rental when the entry is permitted under the lease or applicable law.
Pay utilities that are the tenant’s responsibility. If utilities are allocated among tenants, the landlord must follow applicable Colorado utility-billing requirements and disclose the method used to calculate the tenant’s charges.

Colorado Landlord Responsibilities & Rights

Landlords in Colorado have certain rights when managing their rental properties. They generally have a right to:

Access the rental unit for lawful purposes such as making repairs, conducting inspections, or showing the property to prospective tenants, purchasers, or other authorized parties, provided the entry complies with the lease and applicable law. Colorado does not impose a single general statutory notice period for routine entry, so the lease should clearly address the landlord’s right of access and required notice.
Increase the rent, subject to Colorado’s rent-increase rules. A landlord cannot increase residential rent more than once during any 12-month period of consecutive occupancy. If there is no written rental agreement, the landlord must generally provide at least 60 days’ written notice before increasing rent.
Enforce the terms of the lease agreement when a tenant violates a lawful provision, subject to applicable notice, cure, and eviction requirements.
Seek to evict a tenant when legally permitted. Colorado’s just-cause requirements limit when a residential landlord may terminate a tenancy without the tenant’s consent. Depending on the circumstances, qualifying causes may include nonpayment of rent, certain lease violations, substantial damage or nuisance-related conduct, and specified no-fault circumstances such as substantial renovations, demolition, withdrawal of the property from the rental market, or certain owner/family occupancy situations. Landlords must follow the applicable notice and court procedures.
Require a security deposit, subject to Colorado’s limits. For most residential rentals, Colorado law limits the security deposit to no more than two months’ rent.
Make lawful deductions from a security deposit. A landlord may retain amounts when there is actual cause, such as unpaid rent or utilities or qualifying damage beyond normal wear and tear. Colorado’s security-deposit rules also prohibit deductions for preexisting damage and impose specific limitations on deductions for carpet replacement and painting.

colorado landlord tenant laws and fair housing act

When it comes to responsibilities, Colorado landlords generally have a responsibility to:

Provide and maintain a habitable property. Colorado’s warranty of habitability requires landlords to maintain residential premises in a condition fit for human habitation and to address qualifying conditions that materially interfere with a tenant’s life, health, or safety.
Comply with the terms of the lease or rental agreement and with applicable federal, state, and local housing laws.
Provide tenants with required disclosures and rental-agreement information, including applicable lead-based paint and radon disclosures, required landlord identification information, and the required warranty-of-habitability notice.
Provide reasonable notice before entering a tenant’s rental unit and enter at a reasonable time and for a lawful purpose, subject to emergency situations and specific statutory exceptions.
Make necessary repairs and address qualifying habitability problems within the time frames required by Colorado law. Landlords should respond promptly to tenant complaints and follow the statutory procedures for correcting unsafe or uninhabitable conditions.
Comply with applicable fair housing laws. Landlords cannot discriminate against tenants or prospective tenants based on protected characteristics under federal or Colorado law. They must also provide reasonable accommodations when required by fair housing laws.
Follow Colorado’s eviction procedures when seeking to remove a tenant, including providing the appropriate notice and obtaining a court judgment when required. A landlord generally cannot bypass the legal eviction process by locking a tenant out or otherwise unlawfully removing the tenant.
Return the tenant’s security deposit or provide an itemized statement of deductions within the time required by Colorado law. Generally, a landlord has 30 days after termination of the lease or surrender and acceptance of the premises, whichever occurs later, to return the deposit or provide the required written statement. A lease may allow a longer period, but not more than 60 days.

Colorado Security Deposit Laws

Both landlords and renters are protected by Colorado’s security deposit laws. The following are common questions regarding security deposits in the state of Colorado:

Q: Is there a limit to the amount a landlord can ask for a security deposit?

A: Yes. Under Colorado law, a landlord generally cannot require a security deposit that exceeds two months’ rent under the rental agreement. There is a limited exception beginning January 1, 2027, for certain post-closing occupancy agreements in which a buyer purchases a residence from the tenant and the tenant remains in the property under the agreement.

Q: Must landlords notify the tenant upon receiving their security deposit?

A: Colorado law does not generally require landlords to provide a separate receipt or notification when they receive a security deposit. However, landlords should keep accurate records of the deposit and comply with all applicable requirements when the tenancy ends.

Q: How should landlords store a tenant’s security deposit?

A: Colorado state law does not generally require residential security deposits to be held in a specific type of account or require landlords to pay interest on the deposit. However, local laws may impose additional requirements. For example, certain local jurisdictions have their own rules regarding security deposits, so landlords should check the laws that apply to the specific rental property.

Q: Can a landlord charge a non-refundable security deposit?

A: No. A security deposit is considered the tenant’s property and is intended to be returned at the end of the tenancy, less any lawful deductions. A landlord cannot simply designate a security deposit as “non-refundable.”

Q: What reasons can make a landlord keep all or part of the tenant’s security deposit?

A: A landlord may retain reasonable amounts from a security deposit when there is actual cause to do so. Under Colorado law, permissible reasons include:

Nonpayment of rent
Nonpayment of utility charges
Nonpayment of other lawful charges listed in the lease
Necessary repairs for damage or defective conditions that exceed normal wear and tear and did not exist before the tenancy

A landlord generally cannot deduct from a security deposit for normal wear and tear or for damage or defective conditions that existed before the tenant moved in. Colorado’s 2026 law also places additional restrictions on deductions for carpet replacement and painting. For example, carpet replacement generally requires substantial and irreparable damage beyond normal wear and tear, and deductions for carpet or painting must be limited to the minimum amount necessary to address the damaged area.

Q: How long does a landlord have to return a security deposit?

A: Colorado landlords generally have 30 days after the termination of the lease or surrender and acceptance of the premises, whichever occurs later, to return the security deposit or provide a written statement explaining any deductions. The lease may allow a longer period, but that period cannot exceed 60 days.

If a landlord withholds any portion of the deposit, the written statement must identify the exact reasons for the deductions. Beginning in 2026, tenants can also request relevant documentation supporting the deductions, such as photographs, inspection reports, receipts, invoices, or estimates.

Q: Can a tenant request a move-out inspection?

A: Yes. Beginning January 1, 2026, Colorado law provides tenants with the right to request a walk-through inspection, when reasonable and practicable, before the lease ends or the tenant surrenders the property. The inspection can be conducted in person or through an interactive telecommunications-assisted walk-through. The purpose is to identify damage or defective conditions that go beyond normal wear and tear and did not preexist the tenancy.

Property Ownership Change

In such a case, the landlord must transfer all the deposits to the new owner. Next, he or she must notify the renter that they have transferred their deposits to the new owner. The notice must be written and must state the security deposit amount transferred.

Colorado Small Claims Lawsuits

A small claims court is a court of limited jurisdiction. What this means is that only certain matters may be filed and heard. Unlike other courts, a small claims court offers a quick and inexpensive way of resolving issues.

To bring a case to a Colorado small claims court, a landlord must be seeking to recover $7,500 or less.

Colorado Tenant Rights to Withhold Rent

written rental agreement and landlord tenant laws

Landlords are required to provide habitable housing to their tenants. Failure to do so means tenants have a right to withhold paying rent to compel the landlord to act.

In Colorado specifically, if a building fails structural, health, and safety standards, renters have a right to withhold rent.

Before withholding rent, renters must make sure that the circumstances truly justify their right to withhold rent. Otherwise, it may give the landlord justification to evict them.

Before withholding rent, it’s important to understand a couple of things like the:

Limit on how much rent to withhold and how often you can use a particular remedy.
Type of notice you must give the landlord and the amount of time the landlord must fix the problem before you can withhold.
Type of repair and habitability problems that qualify for withholding rent.

See Colo. Rev. Stat. § 38-12-507 for state law on rent withholding.

Tenant Eviction

An eviction is always a landlords last resort. That being said, Colorado landlords, just like their counterparts elsewhere, have a right to evict their tenants under certain situations. These situations include, for example, the nonpayment of rent, violation of the lease agreement, and illegal acts. Needless to say, the reason for eviction must not be a retaliatory act or for discriminatory reasons.

In doing so, landlords must follow the proper process in order for the process to be successful. Landlords must not engage in improprieties such as “self-help” eviction tactics. Such tactics include locking out the tenant, removing their belongings from the rental unit, or stopping them from using utilities that they previously enjoyed.

Tenant Protection Against Retaliation in Colorado

Acts of retaliation are illegal under Colorado local laws. Acts that may constitute landlord retaliation include the landlord:

Harassing the tenant – in person, by phone, online, or through the mail.
Changing the locks on the tenant’s doors.
Removing the tenant’s possessions from the unit.
Refusing to perform necessary repairs on a renter’s unit.
Refusing to perform necessary maintenance on a renter’s unit.
Threatening to evict the renter.
Decreasing services to the tenant.
Increasing the tenant’s rent.

Generally speaking, landlords may retaliate against a tenant for several reasons. Common ones include a tenant joining or organizing a tenant’s union, or a tenant complaining to the landlord about a breach of the warranty of habitability.

Landlord Access to Rental in Colorado

colorado landlord tenant law and breaking a lease early

Renters have a right to privacy. As such, landlords can’t just enter the rental unit as they wish. They must adhere to the provisions of the lease/ rental agreements or Colorado landlord-tenant laws.

Generally, landlords may enter a tenant’s rental unit under the following situations:

With a tenants permission. If you, as the tenant, need repairs done, there’s nothing wrong with agreeing to a landlord’s request. In fact, tenants should be delighted that the landlord is fixing a problem in their home.
To show the property to potential clients. Tenants must accommodate their landlord’s reasonable efforts to re-rent if they've given written notice or their lease is almost up.
To make needed repairs or improvements. As long as proper notice is served and the entry times are reasonable, a tenant shouldn’t hinder the landlord from performing his or her maintenance responsibilities.
In the event of property abandonment. The landlord doesn’t need a tenants permission to enter if he or she believes they have abandoned the property.

Although there is no statute requiring Colorado landlords to give their renters notice of their planned entry, landlords generally give a “reasonable” notice to their renters. Usually, it’s a 24 hours’ notice.

The entry times must also be reasonable. Say, from 8:00 am -5: 00 pm during weekdays, or from 9:00 am -3.00 pm during weekends, or any other time that is mutually agreed upon by both parties.

Colorado Fair Housing Rules

Passed in 1968, the Fair Housing Act protects tenants from illegal housing discrimination based on several protected characteristics.

In Colorado, the protected classes include creed, sexual orientation, marital status, ancestry, familial status, religion, color, disability, sex, national origin, and race.

The U.S. Department of Housing and Urban Development (HUD) is the federal agency that administers and enforces the act.

Bottom Line

There you have it-- an overview of the landlord-tenant laws in Colorado. By understanding these local laws, both parties to the lease should be able to deal with many legal matters like handling a security deposit even without a legal background. You'll be able to rent out your property successfully.

Frequently Asked Questions

How much can a Colorado landlord charge for a security deposit?

State law generally limits a residential security deposit to no more than two monthly rent payments. Owners should also keep accurate records of the property's condition and any deductions because Colorado has specific requirements governing how deposits are handled and returned.

What screening rules should Denver rental owners keep in mind?

Colorado law includes requirements surrounding portable tenant screening reports and restrictions on how certain financial information may be evaluated. Owners should establish consistent, lawful criteria for prospective tenants and apply those standards uniformly to all prospective tenants to reduce compliance and fair housing risks.

How much notice should I provide before changing rent or lease terms?

The correct timeline depends on the lease structure, the rental period, and the action being taken. For residential tenancies without a written agreement, Colorado requires 60 days' written notice before increasing rent, and landlords generally cannot increase residential rent more than once within a 12 month period. Before acting at the end of any rental period, owners should confirm that the applicable notice and cause requirements have been satisfied.

What records should I keep when a resident reports a serious property condition?

Colorado's warranty of habitability rules make documentation particularly important for residential rental housing. Owners should retain maintenance requests, communications, inspection findings, vendor invoices, repair records, and other documentation showing when a problem was reported and how it was addressed.

What should I document before making a security deposit deduction?

Detailed move in and move out records can help establish whether damage occurred during the tenancy and whether it exceeds normal wear and tear. Colorado's current rules also place additional requirements on deposit deductions and, when requested and reasonably practicable, call for a walk through inspection before the tenancy ends, making photographs, inspection reports, receipts, and repair estimates especially useful.

Does hiring a property manager remove an owner's legal responsibilities?

Professional management can make compliance easier by providing structured processes for screening, lease administration, rent collection, maintenance coordination, inspections, and recordkeeping. Evolve Real Estate & Property Management offers these services throughout the Denver area, but owners should still seek qualified legal advice when a specific dispute or complex legal question arises.
