How much notice does a landlord have to give for unpaid rent in Colorado?
Short answer
Unpaid rent: a written 10-day demand to pay or leave before an eviction can be filed
Notice: At least 10 days after a written demand for the rent or possession is served
For unpaid residential rent, the landlord must serve a written notice giving the tenant ten days to pay the rent or give up possession before the tenant is in unlawful detention. Nonresidential and employer-provided housing agreements keep shorter periods.
