Colorado Eviction Notice

Colorado requires a landlord to serve proper written notice before commencing a Forcible Entry and Detainer (FED) action in court. The required notice period and content depend on the ground for termination. Non-payment of rent requires a 10-day Demand for Compliance or Right to Terminate. Material lease violations require a 10-day Cure or Quit notice. Month-to-month tenancies without cause require at least 21 days' notice, or 91 days for tenants who have occupied the property for 36 months or more. These requirements are governed primarily by C.R.S. § 13-40-104 and C.R.S. § 38-12-402, as well as Colorado HB21-1121 tenant protections.

Notice Type Selection Guide

Select the correct notice type that matches the reason for seeking possession. Using an incorrect notice may require re-service and delay any court filing.

> Critical: This notice is only the first step. The landlord must still file an FED complaint in the appropriate county court and obtain a court order before the tenant can be lawfully removed. Self-help evictions, including changing locks, shutting off utilities, or removing the tenant's belongings, are illegal under Colorado law and may result in significant liability., -
