Eviction Laws in Colorado
Non-payment of rent eviction in Colorado
When a tenant falls behind on rent in Colorado, the landlord must first serve a 10-day pay-or-quit notice. This gives the tenant 10 days to either pay the full amount owed or vacate. If the tenant does neither, the landlord can file an eviction lawsuit — called an unlawful detainer or summary possession action — in Colorado court.
A court order is required before any lockout. The landlord cannot change the locks, shut off utilities, or remove the tenant's belongings before winning a judgment.
Lease violation eviction in Colorado
For non-payment lease violations — unauthorized pets, excess occupants, noise complaints, property damage — the landlord must give 10 days notice. The tenant has 10 days to cure (fix) the violation. If corrected within that window, the tenancy continues. If not cured, the landlord may proceed with filing.
Terminating month-to-month tenancy in Colorado

What counts as an illegal eviction in Colorado?
In Colorado, a landlord who attempts to evict a tenant without following the legal process commits an illegal (self-help) eviction. This includes:
- Changing the locks without a court order
- Removing doors, windows, or the tenant's belongings
- Shutting off utilities (electricity, water, heat)
- Harassment designed to pressure the tenant to leave
Self-help evictions are prohibited in all 50 states and DC. Tenants who experience an illegal lockout can typically seek emergency relief from a court and may be entitled to damages.
