Colorado Month-to-Month Termination Notice Requirements
Colorado requires at least 21 days’ written notice to terminate a month-to-month tenancy for agreements of one to six months. For tenancies of six months or longer, 91 days’ notice is required. These requirements were updated by recent legislation (HB 1098).
Important: Written Notice Required
Colorado requires that termination notice be in writing. Verbal notice is generally not sufficient and may not be enforceable in court. Keep a copy of any notice you send or receive, and consider using certified mail or hand-delivery with a witness to prove delivery.
Colorado Rent Increase Notice Periods
Colorado landlords must provide at least 30 days’ written notice before increasing rent. While Colorado does not have statewide rent control, recent legislation allows local municipalities to enact rent stabilization measures.
