Cal. Civ. Code § 38-12-701
Notice of rent increase.
Operative Text
(1) Notwithstanding any other law, in a nonresidential tenancy of one month or longer but less than six months in which there is no written agreement between the landlord and tenant, a landlord may increase the rent only upon at least twenty-one days' notice to the tenant. (2) (a) Notwithstanding any other law, in a residential tenancy in which there is no written agreement between the landlord and tenant, a landlord may increase the rent only upon at least sixty days' written notice to the tenant. (b) 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 this section.
Colorado Revised Statutes § 38-12-701 establishes minimum notice periods that landlords must give before raising rent in tenancies without a written lease. For qualifying nonresidential month-to-month tenancies (those lasting at least one month but less than six months), at least 21 days' notice is required before a rent increase takes effect. For residential tenancies without a written agreement, the required notice period is longer — at least 60 days, and it must be in writing. The statute also prohibits landlords from using a termination notice as a workaround to impose a rent increase that would otherwise violate these notice requirements.
Plain English — not legal advice.
Under § 38-12-701, operators of residential rental properties without written lease agreements are generally expected to deliver written rent-increase notices at least 60 days before the new rent takes effect. For nonresidential tenancies in the one-month-to-under-six-month range without a written agreement, the minimum notice window is 21 days. Compliant operators also avoid serving termination notices whose primary purpose is to circumvent the notice requirements of this section, as that practice is expressly prohibited by the statute.
General guidance for property managers — not legal advice for your specific situation. Consult an attorney for advice on your case.
Section § 38-12-701 gives residential tenants without a written lease the right to receive at least 60 days' written notice before any rent increase can lawfully take effect. If a landlord serves a termination notice that appears designed primarily to force a rent increase in a way that sidesteps this section, that practice is prohibited under the statute. Tenants who believe a notice violates § 38-12-701 may consider consulting a tenant-rights organization or legal aid provider to understand the options available to them, which can include raising the violation as a defense in a legal proceeding.
