Colorado Rent increase notice
How much notice does a landlord need to give to raise the rent in Colorado?
With no written agreement, a landlord may increase residential rent only upon at least 60 days' written notice (C.R.S. § 38-12-701(2)(a)). C.R.S. § 38-12-701(2)(b) provides that a landlord shall not terminate a residential tenancy in which there is no written agreement by serving a tenant with a notice to terminate tenancy with the primary purpose of increasing a tenant's rent in a manner inconsistent with that section. In residential tenancies, a landlord shall not increase rent more than one time in any twelve-month period of consecutive occupancy by the tenant, regardless of whether there is a written rental agreement for the tenancy, the length of the tenancy, or whether the tenant's rental agreement is for a fixed tenancy, a month-to-month tenancy, or an indefinite term (C.R.S. § 38-12-702(1)). C.R.S. § 38-12-701(1) is a 21-day notice rule for certain nonresidential tenancies and is not part of this residential answer. Official source notes: C.R.S. § 38-12-701 was added in L. 2017 (SB 17-245), the entire section was amended in L. 2021 (HB 21-1121, effective June 25, 2021), and subsection (2)(b) was amended in L. 2024 (HB 24-1098, effective April 19, 2024). C.R.S. § 38-12-702 was added in L. 2021 (HB 21-1121, effective June 25, 2021). No 2025 or 2026 amendment to either section appears in the official 2026 CRS source notes.

How this works in Colorado
In Colorado, if there is no written agreement, a landlord may increase the rent only upon at least 60 days' written notice. Rent may not be raised more than once in any 12-month period of occupancy, whatever the lease type.
Worked example for Colorado
Example: There is no written agreement, and you want an increase to take effect on August 1, 2026. At least 60 days' written notice is due by June 2, 2026. Rent may not be raised more than once in any 12-month period of occupancy, so after that increase it may not be raised again in that 12-month period, whatever the lease type.
