Adverse possession requires 18 years of continuous unauthorized possession under C.R.S. § 38-41-101
Colorado sets its general adverse possession period at 18 years under C.R.S. § 38-41-101 — a mid-range window that sits well above the five-year statutes in states like California but far below the longest in the country. For a Colorado landlord, that 18-year clock is a meaningful safety margin: no occupant can convert your title to theirs after a few months of squatting, and ordinary turnover or a short vacancy comes nowhere near the threshold. The real exposure is the long-neglected property — an inherited lot, an out-of-state rental, or a vacant parcel nobody checks for years.
There is one important shortcut. Colorado cuts the period to just 7 years where the occupant holds under color of title and has paid the property taxes for that stretch. That is a much shorter runway, and it is why tax delinquency and unrecorded claims deserve a landlord's attention. The practical takeaway: monitor what you own, and treat any unauthorized occupant as a clock you need to stop early.
To claim title by adverse possession in Colorado, an occupant must satisfy five elements for the full statutory period: possession that is hostile (without the owner's permission), actual (physically using the land), open and notorious (visible enough that a diligent owner would notice), exclusive (not shared with the true owner or the public), and continuous for the entire 18 years required by C.R.S. § 38-41-101.
The statute also recognizes a shorter route. Where the occupant possesses under color of title — a written instrument that appears to grant ownership but is legally defective — and has paid all property taxes during that time, the period shrinks to 7 years. Permission defeats every claim: a tenant who pays rent or holds under any agreement is never hostile, so a documented lease or license is itself a strong defense.
Adverse possession only ripens through years of uninterrupted, unchallenged occupancy. Any act that breaks continuity restarts the count from zero. A single eviction filing or a written demand to vacate resets the clock — the occupant can no longer claim the run of years was unbroken or unchallenged.
For Colorado owners, prevention is cheap relative to the 18-year stakes. Inspect vacant and remote properties on a schedule, keep property taxes current so no occupant can layer on the 7-year color-of-title route, and grant written permission where appropriate — a license or lease converts a potential trespasser into a permissive occupant who can never satisfy the hostility element. Record your deed, post no-trespassing notice on vacant land, and act the moment you discover an unauthorized occupant rather than waiting to see whether they leave.
Colorado law draws a sharp line between two situations landlords often confuse. A holdover tenant entered lawfully under a lease and simply stayed past its end; a squatter never had permission at all. The distinction matters for paperwork, but the removal rule is the same: you cannot do it yourself.
Self-help eviction is illegal in Colorado. Changing the locks, removing the occupant's belongings, or shutting off utilities to force someone out exposes you to liability — even when the person plainly has no right to be there. Heat, water, and electricity cannot be weaponized as an eviction tool. Cutting them off can trigger damages and undercut your own case. The only lawful path runs through the court, and shortcuts tend to cost far more than the delay they try to avoid.
To remove a holdover tenant or squatter in Colorado, use the court process rather than confrontation. The sequence begins with a written notice to vacate (a demand for possession). If the occupant does not leave, you file a forcible entry and detainer — Colorado's eviction action — in the county court where the property sits, and serve the occupant.
The court sets a hearing; if you prevail, the judge issues a judgment for possession, and a sheriff or authorized officer carries out the removal. Only law enforcement acting on a court order may physically put the occupant out. This same filing is what resets the adverse possession clock, so acting promptly does double duty — it recovers your property and it documents that the occupancy was challenged, defeating any future claim under the 18-year period. Keep copies of every notice, filing, and proof of service.
There is an important legal distinction between these two types of unauthorized occupants. A holdover tenant is a former leaseholder, someone who once had a valid lease who remains in the unit after that lease has expired without the landlord's consent and without executing a new lease. In Colorado, holdover tenants are typically treated as month-to-month tenants or as tenants at sufferance depending on whether the landlord continues to accept rent. They must be removed through the formal eviction process with appropriate notice.
A squatter (or trespasser) is someone who entered the property without any prior legal right to do so, they never held a lease with the landlord. Despite having no legal right of occupancy from day one, squatters cannot be physically removed by the landlord without a court order in Colorado. Changing the locks, removing belongings, or shutting off utilities to force a squatter out constitutes illegal self-help eviction and can expose the landlord to civil liability.
In Colorado, the general adverse possession period is 18 years of continuous, open, hostile, actual, and exclusive possession under C.R.S. § 38-41-101. That period drops to 7 years where the occupant holds under color of title — a defective written instrument that appears to convey ownership — and has paid the property taxes throughout. Anything short of the full statutory term cannot support a claim of ownership.
Not on their own in most cases. Because squatters often raise a claim of a right to be present, police generally treat it as a civil matter and will not simply evict someone on request. The lawful route is a court eviction (forcible entry and detainer): after you obtain a judgment for possession, a sheriff or authorized officer carries out the removal. Trying to force the issue through lockouts or utility shutoffs is illegal self-help and can backfire on the owner.
A holdover tenant entered the property lawfully under a lease and stayed after it ended, so their original occupancy was permissive. A squatter never had permission to begin with. The practical difference is the notice and paperwork, but removal is identical: both must be handled through Colorado's court eviction process, and self-help removal is illegal against either one. Because a holdover's possession started with permission, it is generally not hostile and does not build an adverse possession claim.
Stop the clock before it runs. Inspect vacant and remote properties regularly, keep property taxes paid so no one can use the 7-year color-of-title shortcut, and grant written permission (a lease or license) where appropriate, since permission defeats the hostility element. If you find an unauthorized occupant, act fast: a single eviction filing or written demand to vacate resets the 18-year period under C.R.S. § 38-41-101. Record your deed and document every notice you send.
