Challenging Illegal Rent Increases in Colorado

Receiving a rent increase notice can be stressful, especially if the increase seems unfair or possibly illegal. In Colorado, rent control laws are limited, but renters still have legal protections against improper or retaliatory rent hikes. Knowing how to respond helps ensure your rights are respected and that you aren't subject to unlawful changes in your housing costs.

Understanding Colorado Rent Increase Laws

Colorado does not have statewide rent control or rent stabilization. However, Colorado Revised Statutes Title 38, Article 12 sets important rules for rental agreements and notice periods for rent increases. Local ordinances may provide additional tenant protections, so always check with your city or county.

  • Notice Requirement: Landlords must provide at least 21 days' written notice before increasing rent on a month-to-month lease. For longer leases, the lease terms apply.
  • No statewide rent cap: Landlords can generally set rents, but cannot raise rent in a discriminatory or retaliatory manner.
  • No rent control: Local governments are not allowed to impose rent control policies in Colorado.

If you suspect a rent increase is illegal—for example, if you did not receive adequate notice, or if your landlord is increasing rent as retaliation for exercising your tenant rights—you can take action.

Spotting an Illegal Rent Increase

Illegal rent increases in Colorado may involve:

  • Insufficient written notice of the rent increase
  • Rent increases during a fixed-term lease without a specific clause allowing it
  • Increases that serve as retaliation because you reported code violations or exercised other legal rights
  • Increases based on discrimination (race, gender, disability, etc.) in violation of the Federal Fair Housing Act

How to Challenge an Illegal Rent Increase in Colorado

It's important to act quickly if you believe your landlord has made an illegal rent increase. The following steps guide you through the process:

1. Review Your Lease and the Law

  • Check the length of your lease and any specific clauses about rent increases.
  • Confirm the notice period – has your landlord given you at least 21 days' written notice for a periodic (month-to-month) lease?
  • Assess whether the increase appears to be discriminatory or retaliatory, which is not permitted by law.

2. Talk to Your Landlord

Start by having a polite and written conversation with your landlord or property manager. Explain your concerns and ask for clarification or a correction if the notice or increase is contrary to the law.

3. Document Everything

  • Keep copies of all correspondence (emails, letters, texts) with your landlord.
  • Save a copy of the rent increase notice and anything that shows why you believe it may be illegal.

4. File a Complaint with the Colorado Civil Rights Division (CCRD)

If you believe the increase is based on discrimination or retaliation, you can file a complaint with the Colorado Civil Rights Division (CCRD):

  • Form name: Housing Discrimination Complaint Form
  • When to use: If you have evidence that the rent increase was motivated by your race, national origin, disability, sex, or because you exercised protected tenant rights.
  • Submit via CCRD Portal
  • Example: Your landlord increased the rent after you reported a code violation to the city office. You can submit this form to CCRD, attaching your documentation.

5. Seek Mediation or Legal Advice

If your landlord does not resolve the issue, consider seeking help from legal aid or mediation services. The Colorado Judicial Branch does not have a specific residential tenancy tribunal, but rent and eviction disputes are handled in county courts. For more information, visit the Colorado Judicial Branch website. You may also want to consult with qualified legal services such as Colorado Legal Services.

Consider consulting with local tenant advocacy organizations for guidance and support navigating your specific situation.

Relevant Official Forms and Where to Find Them

  • Housing Discrimination Complaint Form (Colorado Civil Rights Division): Submit complaint online if your rights under the Fair Housing Act have been violated.
  • Court Filings for Rent Disputes: There is no specific "Rent Increase Challenge" form. If court action is necessary, you may need to file a civil complaint in Colorado County Court.
