🏔️ Colorado 21-Day Notice to Terminate Month-to-Month Tenancy
Notice of Non-Renewal — No Cause Required
MONTH-TO-MONTH TERMINATION: Use this notice to end a month-to-month tenancy without needing to state a reason. Under HB21-1121, Colorado extended this from 7 days to 21 calendar days. The termination date must align with the end of a rental period. This notice cannot be retaliatory or discriminatory.
📅 Notice & Termination Dates
Count carefully: The termination date must be at least 21 days after service and align with the end of a rental period. If rent is due the 1st and you serve on January 10th — February 1st is less than 21 days away, so the earliest termination is March 1st.

The 21-Day Notice to Terminate ends a month-to-month rental agreement when the landlord chooses not to continue the tenancy. Under C.R.S. § 13-40-107(1)(c) as amended by HB21-1121, this notice period was extended from 7 days to 21 days, giving tenants more time to secure alternative housing.
Key Rules for Colorado Landlords
- Must be served at least 21 calendar days before the end of the rental period
- The termination date must coincide with the last day of a rental period
- No reason is required — this is a no-cause termination
- Cannot be issued within 12 months of a tenant exercising a legal right
- Federal and state Fair Housing laws still apply — termination cannot be discriminatory
Colorado Has No Rent Control or Just-Cause Requirements
Under C.R.S. § 38-12-301, Colorado state law preempts local rent control ordinances. No Colorado city or county can require “just cause” for eviction. Landlords may terminate month-to-month tenancies for any lawful, non-discriminatory, non-retaliatory reason.
