🏔 Colorado Rent Increase Notice
Formal Written Notice of Rent Increase with Required Lead Time
PROPER NOTICE IS REQUIRED: Colorado has no rent control — landlords can raise rent by any amount. However, proper advance written notice is required. For month-to-month tenancies, provide notice at least 21 days before the end of the rental period. For fixed-term leases, the increase only takes effect upon renewal. This form auto-calculates the effective date.

Colorado has no statewide rent control. Under C.R.S. § 38-12-301, local jurisdictions are also preempted from enacting rent control ordinances. Landlords may increase rent by any amount, but must provide proper advance written notice.
Notice Requirements by Tenancy Type
| Tenancy Type | Required Notice | When Effective |
|---|---|---|
| Month-to-Month | At least 21 days | First day of next rental period after notice period expires |
| Fixed-Term Lease | Per lease terms | At lease renewal only — cannot increase mid-lease without consent |
| Week-to-Week | At least 21 days | First day of next rental period |
Retaliation Prohibition
Even without rent control, Colorado prohibits retaliatory rent increases. A landlord cannot raise rent within 12 months of a tenant exercising a legal right — such as reporting a habitability issue, requesting repairs, or participating in tenant organizing — if retaliation is the motivation.
Best Practices for Rent Increases
- Give notice earlier than required — 30-60 days notice builds tenant goodwill
- Provide a brief, professional reason — increases transparency and reduces disputes
- Send by certified mail to document delivery
- Keep a copy of the signed notice in your tenant file
