Arapahoe County, CO Rental Property Rules: Just Cause Eviction (2026)

With certain exceptions, the act prohibits a landlord from evicting a residential tenant unless the landlord has cause for eviction. Cause exists only when: A tenant or lessee is guilty of an unlawful detention of real property under certain circumstances described in existing law, as amended by the act; A tenant or lessee engages in conduct that creates a nuisance or disturbance that interferes with the quiet enjoyment of the landlord or other tenants at the property or an immediately adjacent property, or where the tenant negligently damaged the property; or Conditions exist constituting grounds for a "no-fault eviction". The following conditions constitute grounds for a "no-fault eviction" of a residential tenant, with certain limitations: Demolition or conversion of the residential premises; Substantial repairs or renovations to the residential premises; Occupancy of the residential premises is assumed by the landlord or a family member of the landlord; Withdrawal of the residential premises from the rental market for the purpose of selling the residential premises; A tenant refuses to sign a new lease with reasonable terms; and A tenant has a history of nonpayment of rent. If a landlord proceeds with an eviction of a tenant without cause, the tenant may seek relief as provided in existing laws concerning unlawful removal of a tenant and may assert the landlord's violation as an affirmative defense to an eviction proceeding.
