Rent Increase Notice Requirements in Colorado

At a glance

Requirements one by one

Notice period and form

For a residential tenancy with no written agreement, Colo. Rev. Stat. § 38-12-701(2)(a) requires at least 60 days' written notice before an increase. The section does not prescribe special content or a service method, and it does not state a general advance-notice period for a tenancy governed by a written agreement.

Subsection (2)(b) also prevents a landlord from using a termination notice with the primary purpose of obtaining an increase inconsistent with the section. That provision is not a separate termination-notice period for this survey.

Frequency limit

Section 38-12-702 permits no more than one rent increase in any 12-month period of the tenant's consecutive occupancy. The statute makes the limit apply regardless of whether the agreement is written, how long the tenancy lasts, or whether it is fixed, month-to-month, or indefinite.

The section regulates frequency, not amount. It states no statewide percentage or dollar ceiling and no part-7 damages formula.

What trips people up

The 60-day rule is not universal. Its text applies when there is no written agreement between landlord and tenant. The once-per-12-month rule is broader and expressly reaches written and fixed tenancies.

Coverage of a fixed tenancy by the frequency limit does not itself authorize a landlord to rewrite the rent before the agreed term ends. Sections 38-12-701 and -702 do not answer whether a particular written agreement permits a midterm change.

Common questions

Does Colorado cap the percentage of an increase?

Not under these general state sections. Section 38-12-702 limits how often rent may increase, not the size of an increase. Local law may separately matter.

Does a written lease get the 60-day rule?

Section 38-12-701(2)(a) states the 60-day requirement for a residential tenancy in which there is no written agreement. The written agreement and other applicable law must be checked for a written tenancy.

Can the landlord raise rent twice if both notices were timely?

Not within one 12-month period of consecutive occupancy. Section 38-12-702 imposes the frequency limit independently of the notice rule.
