Colorado Rent Increase Notice Letter

State Cap: No statute. Colorado has no statewide statutory limit on rent increase amounts, and municipalities are statutorily prohibited from enacting local rent control (C.R.S. § 38-12-301). However, landlords cannot increase rent more than once in any 12-month period for the same tenant (C.R.S. § 38-12-702(1)).

Notice Period: 60 days before the effective date of the rent increase for month-to-month tenancies or tenancies without a written lease agreement (C.R.S. § 38-12-701(2)(a)).

Proof of Service: Landlords must deliver written notice by personal delivery to the tenant, leaving a copy with a residing family member over age 15, or posting in a conspicuous place on the property (C.R.S. § 13-40-108).

Prohibited Acts: Landlords cannot increase rent as retaliation against tenants reporting habitability violations, joining a tenants’ association, or exercising statutory rights, or for discriminatory reasons under fair housing laws (C.R.S. § 38-12-509(1); C.R.S. § 24-34-502(1)).
