- Landlords in Colorado must provide tenants with at least 60 days’ written notice before a rent increase takes effect, regardless of whether there is a written or oral lease agreement.
- For rent increases effective April 1, 2025, landlords needed to give notice by January 31, 2025.
- For month-to-month leases, the minimum notice is 30 days, but if the lease or local ordinances require a longer notice, the longer period applies.
Frequency and Timing
- Rent can only be increased once within a 12-month period for the same tenant, including in mobile home parks.
- Landlords cannot increase rent in the middle of a fixed-term lease unless the lease specifically allows for it.
Amount of Increase
- There are no statewide rent control laws in Colorado. This means there is no legal cap on how much a landlord can raise the rent.
- Cities and counties in Colorado are prohibited from enacting local rent control measures.
- However, rent increases cannot be retaliatory or discriminatory. Increases based on protected characteristics (such as race, gender, religion, familial status, national origin, disability, etc.) are illegal under federal and state law.
Special Considerations
- For mobile home parks, landlords cannot increase lot rent if the park does not have a current, active license.
- If you believe a rent increase was not communicated properly or is otherwise unlawful, you can seek assistance from the Colorado Division of Housing or Colorado Legal Services.
Recent Legislation
- A 2025 bill (HB25-1092) proposed clarifying that rent increases up to current market rates are legal if supported by documentation, but this bill did not pass and is not law.
