A property manager relocating from Phoenix to Denver assumes the compliance framework is similar - state landlord-tenant law, standard lease forms, a familiar eviction process. Within six months, they receive a notice of violation from the City of Denver for operating a rental property without a license. They issue a rent demand without including the required Denver Tenant Rights and Resources guide. And they structure a security deposit above the state cap that Colorado passed in 2023.

Denver tenant protections operate on two distinct levels: Colorado state law, which applies to every residential rental in the state, and Denver-specific local ordinances that add a second compliance layer operating only within the city and county limits. Property managers entering the Denver market from other states - and even experienced Colorado operators working primarily outside Denver - frequently miss the local layer entirely.

This guide maps both levels: the statewide Colorado framework that forms the floor, and the Denver-specific requirements that raise it.

The Two-Layer Framework: State Law and Denver Local Ordinances

Understanding compliance in Denver requires holding two frameworks in mind simultaneously.

• Colorado state law : sets the minimum standards for all residential landlord-tenant relationships across the state. These include just cause eviction protections, security deposit caps, late fee limits, warranty of habitability requirements, and mandatory mediation for certain tenants. Every landlord in Colorado - Denver or otherwise - must comply with these requirements.

• Denver local ordinances : add requirements that go beyond state law and apply only within the City and County of Denver. These include the mandatory rental licensing program, the obligation to provide tenants with a legally required information guide at specific trigger points, expanded anti-discrimination protections, and the Immigrant Tenant Protection Act. A landlord operating in Aurora or Lakewood faces only state law obligations. A landlord operating in Denver faces both.

Understanding Denver landlord tenant law means understanding where state law ends and local law begins - and what each one actually requires.

Colorado State Law: The Compliance Floor

Just Cause Eviction: HB24-1098

The most operationally significant change to Colorado landlord tenant law in recent years is the just cause eviction requirement established by House Bill 24-1098, signed by Governor Polis on April 19, 2024, and effective immediately upon signing.

Under HB24-1098, confirmed from the official Colorado General Assembly bill summary and multiple Colorado law firm analyses, landlords are prohibited from evicting a residential tenant - or refusing to renew a lease - unless the landlord has cause for eviction. The law applies to most residential tenancies, with specific exceptions including short-term rental properties, certain owner-occupied units, employer-provided housing, and tenants who have not resided at the property for at least 12 months.

Grounds for eviction under HB24-1098 include:

• Nonpayment of rent

• Substantial lease violations (with proper notice and opportunity to cure)

• Conduct creating a nuisance or disturbance

• Negligent property damage

• Criminal activity on the premises

No-fault grounds (requiring 90 days' written notice) include: demolition or conversion of the premises; substantial repairs or renovations; landlord or family member occupancy; withdrawal from the rental market to sell; tenant's refusal to sign a new lease with reasonable terms; and a tenant's history of repeated late rent payments.

Non-renewal of a lease without cause is treated as an eviction under this law.
Retaliation is prohibited: landlords cannot evict in retaliation for tenants exercising their legal rights, including making good-faith habitability complaints or joining a tenant organization. Tenants may assert a landlord's violation of HB24-1098 as an affirmative defense in eviction proceedings. Property managers should consult qualified Colorado counsel for specific application of this law to their portfolio circumstances.

Security Deposit Cap: C.R.S. §38-12-103

Colorado law caps security deposits at two months' rent. Confirmed from the Denver Tenant Rights and Resources guide published by the City and County of Denver: "State law prohibits a landlord from requiring a tenant to submit a security deposit in an amount that exceeds the amount of two monthly rent payments under the rental agreement."

• Security deposit return :

  Under C.R.S. §38-12-103, confirmed directly from the primary statute at FindLaw and Justia, landlords must return the security deposit (or provide an itemized statement of deductions) within one month after the termination of the lease or surrender and acceptance of the premises, whichever occurs later, unless the lease specifies a longer period not exceeding 60 days. The landlord is deemed to comply by mailing the statement and any payment to the tenant's last known address.

• Walk-through right (HB25-1249, effective January 1, 2026) :

  Under legislation signed June 3, 2025, either a landlord or tenant may request a walk-through inspection of the dwelling unit before the lease terminates and after the tenant has had the opportunity to remove furniture. The walk-through may be conducted in person or via a telecommunication-assisted interactive walk-through. The law also introduced treble damages for bad-faith security deposit retention.

• Pet deposits :

  Under C.R.S. §38-12-106, effective January 1, 2024, refundable pet security deposits are capped at $300 per pet. Monthly pet rent cannot exceed $35 per pet or 1.5% of the monthly rent, whichever is greater. Landlords cannot charge additional pet deposits or pet rent for service animals or emotional support animals.

RIOO's property accounting module supports per-unit deposit tracking to ensure deposits stay within the Colorado statutory cap and return deadlines are documented across the portfolio.

Late Fee Limits: C.R.S. §38-12-105

Colorado law caps late fees at the greater of $50 or 5% of the monthly rent. Late fees cannot be charged until rent is at least 7 days past due. Landlords cannot charge interest on a late fee, and rent payments cannot be applied to outstanding late fees before rent itself is paid.

If a landlord violates Colorado's late fee rules, the tenant can notify the landlord in writing and demand $50 per violation. If the landlord fails to correct the violation within 7 days, the tenant may sue and seek compensatory damages, a penalty of $150 to $1,000 per violation, and attorney's fees.

Warranty of Habitability: SB24-094

Senate Bill 24-094, effective May 3, 2024, substantially updated Colorado's warranty of habitability framework. The entire habitability section of Colorado statute was repealed and re-enacted with significant changes. Confirmed from the Colorado Bar Association's Colorado Lawyer publication and the official Colorado General Assembly bill summary:

Remedial action start timelines:

• Ordinary uninhabitable conditions: landlord must start remedial action within 72 hours of notice

• Conditions materially interfering with life, health, or safety (including hazardous gas leaks, loss of heat between October and April, vermin infestation, broken elevators preventing access for tenants with disabilities): landlord must start within 24 hours

Completion timelines (rebuttable presumptions):

• Ordinary conditions: presumed complete within 14 days

• Emergency conditions: presumed complete within 7 days

These completion timelines establish rebuttable presumptions - a landlord who can demonstrate that circumstances outside their reasonable control prevented timely completion may rebut the presumption. Property managers should document all remediation efforts contemporaneously.

• Temporary housing:
  If an uninhabitable condition materially interferes with the tenant's life, health, or safety and requires the tenant to vacate during remediation, landlords may be required to provide comparable temporary housing for up to 60 days.

• Recurring issue protection:
  If the same habitability issue reoccurs within a 6-month period, the tenant may terminate the lease.

• Record-keeping:
  Landlords must maintain records of all communications and actions taken regarding habitability issues.

Property managers should consult qualified Colorado counsel regarding specific SB24-094 obligations for their portfolio circumstances.

Mandatory Mediation for Cash Assistance Tenants: HB23-1120

Under House Bill 23-1120, confirmed from the official Colorado General Assembly primary text, landlords and tenants must participate in mandatory mediation before an eviction action may be filed if the tenant receives:

• Supplemental Security Income (SSI)

• Federal Social Security Disability Insurance (SSDI)

• Cash assistance through the Colorado Works program

Mediation requirements:

• Must be conducted by a trained neutral third party

• Must take place within 14 calendar days after the landlord requests it

• Must be provided at no cost to the tenant; the landlord pays their own portion

Exemptions:
Landlords with 5 or fewer single-family rental homes AND no more than 5 total rental units are exempt. A tenant who does not disclose their cash assistance status also removes the mediation requirement.

Consequence:
Failure to comply with mandatory mediation is an affirmative defense in eviction proceedings - the court must dismiss the case without prejudice if mediation was required but not completed.

Every eviction demand notice must include a statement that cash assistance tenants have the right to mediation before the landlord files an eviction complaint with the court.

Prohibited Lease Clauses

Colorado law prohibits certain provisions from appearing in residential lease agreements, including:

• Waivers of the right to a jury trial

• Waivers of the right to pursue class-action claims

• Unreasonable liquidated damages clauses tied to eviction notices or eviction actions

• Waivers of mandatory mediation or clauses allowing landlords to recoup mediation costs from tenants

Recent 2025-2026 State Law Updates

Domestic violence protections (HB25-1168, effective August 6, 2025): Strengthened protections for survivors of domestic abuse, domestic violence, unlawful sexual behavior, or stalking. Landlords must offer repayment plans when rent issues are related to abuse. Survivors can terminate leases, limit financial liability for damage caused by abusers, and courts can suppress housing case records when public access could endanger survivors.

Transparent pricing (HB25-1090, effective January 1, 2026): Confirmed from the Colorado General Assembly official bill summary, landlords must display the full total price - including all fees and service charges - in advertisements and lease agreements. Hidden fees added after the initial quote are prohibited.

No Rent Control: The Colorado Preemption

Before addressing Denver's local additions, one crucial point: Colorado prohibits rent control. Under the Rental Housing Act of 1981, municipalities and counties are barred from enacting local rent control or rent stabilization ordinances. Denver cannot cap how much landlords raise rents - and no Colorado municipality can.

What Colorado does require is procedural:

• Landlords can raise rent no more than once per 12-month period of continuous occupancy

• Month-to-month tenants must receive at least 21 days' written notice before a rent increase

• Rent increases cannot be retaliatory

Tenant advocates have repeatedly introduced bills to allow local rent control in Colorado, and all have failed to pass in the General Assembly. Property managers in Denver should understand that while rent increases face no cap, they face procedural and timing constraints.

Denver Local Ordinances: The Additional Layer

Denver Rental Licensing Requirement

This is the most frequently missed Denver-specific obligation for property managers new to the market. Since May 3, 2021, all residential rental properties in Denver must obtain a rental license from the City and County of Denver. As of January 1, 2024, this requirement expanded to include single-family rental homes.

Key requirements confirmed from denvergov.org:

• Every residential rental property - multi-unit, single-unit, or accessory dwelling unit - requires a license

• A third-party inspection must be passed to obtain the license

• Licenses must be renewed every 4 years, unless there is a change in property ownership

• Tenants can verify whether their rental is properly licensed online through the Denver website

Operating a rental property in Denver without a valid license is a municipal ordinance violation. Property managers adding Denver units to their portfolios must account for the licensing timeline before offering units for rent.

Required Tenant Rights and Resources Guide

Denver has a city-specific obligation that goes beyond state law: landlords must provide tenants with the Denver Tenant Rights and Resources guide published by the Denver Department of Housing Stability (HOST) at two specific trigger points:

1. At lease signing - the guide must be provided to every new tenant

2. With any demand for rent or possession - when a landlord issues a rent demand or eviction notice, a copy of the guide must be included

Denver Anti-Discrimination Ordinance

The Colorado Fair Housing Act protects against discrimination based on disability, race, creed, color, sex, sexual orientation, gender identity, gender expression, marital status, family status, veteran or military status, religion, national origin, ancestry, and source of income.

Denver's local Anti-Discrimination Ordinance expands these protections to also include - confirmed from the Denver Renter's Housing Handbook published by the Denver Department of Housing Stability:

• Ethnicity

• Citizenship status

• Immigration status

• Age (40 years and older)

• Protective hairstyle

These additional categories are Denver-specific and are enforced by the Denver Anti-Discrimination Office (DADO).

Source of income protections also require Denver landlords to accept any lawful and verifiable source of money paid directly, indirectly, or on behalf of a tenant, including housing vouchers.

Immigrant Tenant Protection Act

Denver's Immigrant Tenant Protection Act (ITPA) specifically prohibits landlords from:

• Requesting, demanding, or collecting information related to a tenant's immigration or citizenship status unless required by law

• Disclosing or threatening to disclose immigration or citizenship status to harass or intimidate a tenant

• Requiring different or additional documentation from a tenant based on perceived immigration or citizenship status

Denver Housing Code

Denver's residential housing standards are governed by Denver Municipal Code Chapter 27, administered through the Denver Department of Public Health and Environment. Landlords must maintain minimum standards for: basic equipment and facilities, lighting, ventilation, heating, insect and rodent control, safety, sanitation, and utilities.

Violations can be reported to the Denver Department of Public Health and Environment. This layer of code enforcement exists separately from state habitability law and gives Denver tenants a local enforcement mechanism for housing condition complaints.

Denver City-Funded Eviction Legal Assistance

The City and County of Denver provides funding for free legal services for low- and moderate-income individuals facing eviction, through the Department of Housing Stability. This city-funded legal assistance program means Denver tenants facing eviction have access to legal representation in ways that tenants in most other Colorado cities do not.

Denver also operates emergency rental assistance through HOST. Tenants facing financial hardship who need help paying rent or utilities can call 1-844-926-6632 or visit denvergov.org/renthelp.

For property managers, the city-funded legal assistance program means that unrepresented tenants in Denver eviction proceedings are less common than in other markets - and procedural compliance failures in notices or lease documents are more likely to be identified and raised as defenses.

Common Compliance Failures in the Denver Market

1. Operating without a rental license.
Since January 1, 2024, this includes single-family rental homes. Every residential rental in Denver requires a valid license before tenants can lawfully occupy the unit.

2. Failing to include the Tenant Rights and Resources guide with rent demands.
This Denver-specific requirement is separate from state law obligations. Missing it from a demand notice is a procedural defect.

3. Charging security deposits above two months' rent.
The Colorado cap has been in effect since August 2023. Deposits above this limit violate C.R.S. §38-12-103.

4. Charging late fees before the 7-day grace period.
Colorado law requires rent to be at least 7 days past due before any late fee can be assessed.

5. Non-renewing a lease without documenting just cause for qualifying tenants.
Under HB24-1098, lease non-renewal for tenants who have resided at the property for at least 12 months requires just cause or proper no-fault grounds with 90 days' notice.

6. Failing to initiate repairs within the SB24-094 timelines.
24 hours for conditions materially affecting life, health, or safety; 72 hours for ordinary uninhabitable conditions.

7. Applying a lease clause waiving jury trial or class-action rights.
These provisions are prohibited under Colorado law and unenforceable regardless of tenant signature.

8. Missing the mandatory mediation requirement for cash assistance tenants.
Eviction filings without completing required mediation are dismissed without prejudice - forcing the landlord to restart the entire process.

Frequently Asked Questions

1. Does Denver have rent control?
No. Colorado's Rental Housing Act of 1981 prohibits municipalities from enacting rent control or rent stabilization. Denver cannot cap rent increases. However, landlords may raise rent no more than once per 12-month period, and month-to-month tenants must receive at least 21 days' written notice.

2. Do Denver landlords need a rental license?
Yes. All residential rental properties in Denver - including single-family homes as of January 1, 2024 - require a rental license from the City of Denver, obtained after passing a third-party inspection. Licenses renew every 4 years.

3. What is the security deposit cap in Colorado?
Under C.R.S. §38-12-103, landlords cannot require a security deposit exceeding two months' rent. Pet deposits are separately capped at $300 per pet, with monthly pet rent capped at $35 or 1.5% of rent, whichever is greater.

4. What is the just cause eviction requirement in Colorado?
Under HB24-1098, landlords must have documented just cause to evict or refuse lease renewal for tenants who have resided at the property for at least 12 months. No-fault grounds such as demolition, substantial renovation, or landlord occupancy require 90 days' written notice. Certain exceptions apply, including for short-term rentals and owner-occupied premises. Property managers should consult Colorado counsel for specific application.

5. What is Denver's Tenant Rights and Resources guide requirement?
Denver landlords must provide the city-produced Tenant Rights and Resources guide to every new tenant at lease signing and with every rent demand or eviction notice. This is a Denver-specific requirement separate from state law.

6. How does the Denver Anti-Discrimination Ordinance differ from state fair housing law?
Denver's ordinance expands protections to include ethnicity, citizenship status, immigration status, age (40+), and protective hairstyle - categories not explicitly covered by the Colorado Fair Housing Act. Violations are enforced by the Denver Anti-Discrimination Office (DADO).

7. What are the late fee limits in Colorado?
Under C.R.S. §38-12-105, late fees cannot exceed the greater of $50 or 5% of monthly rent and cannot be charged until rent is at least 7 days past due. Landlords cannot charge interest on late fees.

8. What happens if mandatory mediation is skipped before evicting a cash assistance tenant?
Failure to complete required mediation under HB23-1120 is an affirmative defense in eviction proceedings. The court must dismiss the case without prejudice, requiring the landlord to restart the entire process from the beginning.

Conclusion

Denver tenant protections operate at two levels that property managers must track independently. Colorado state law - including just cause eviction, the security deposit cap, late fee limits, warranty of habitability timelines, and mandatory mediation for qualifying tenants - applies to every residential rental in the state. Denver local ordinances then layer on top: rental licensing, the Tenant Rights and Resources guide requirement, expanded anti-discrimination protections, the Immigrant Tenant Protection Act, local housing code enforcement, and city-funded legal assistance that makes procedural compliance more critical than ever.

For property management companies expanding into Denver from other Colorado markets or from out of state, the compliance framework is more demanding than the state floor alone. Understanding where state law ends and local law begins - and building both into operational workflows - is what separates compliant Denver property management from costly exposure.

RIOO supports Denver property management operations through lease management, property accounting, move-in and move-out workflows, and workflow and customization tools - helping management teams organize the documentation, deadline tracking, and lease compliance workflows that Denver's layered regulatory framework requires.
