How much notice a tenant and a landlord must give to end a month-to-month tenancy in Colorado, and the statute that controls — verified July 2026.
Tenant: 21 days (the '1 month to <6 months' tier).
Landlord: Tiered by tenancy length: 21 days if 1–6 months; 28 days if 6 months–1 year; 91 days if 1+ year. Statewide just-cause (HB24-1098) also limits no-cause non-renewals. A long-staying month-to-month tenant (1+ year) is owed 91 days — the tier is by tenancy length, not rental period.
