Squatters in Colorado: what the law really says

"Squatters' rights" is a phrase that generates far more anxiety than the underlying law justifies — and simultaneously leads owners to do the one thing guaranteed to make their situation worse.

Start by identifying which of three situations you actually have. They look similar and are legally distinct.

1. Adverse possession — rare, slow, and probably not your problem

Adverse possession is the legal doctrine that lets someone eventually acquire title by occupying property. In Colorado it requires possession that is actual, open and notorious, hostile, exclusive and continuous for a long statutory period — measured in years, not months. Colorado tightened its requirements in response to abuse of the doctrine, and courts apply them strictly.

In practice this almost never applies to a rental property that anyone is paying attention to. Someone occupying a house for eighteen months does not acquire it. Adverse possession claims typically involve boundary disputes and long-abandoned parcels, not tenancies gone wrong.

If you are worried about it: is anyone visiting the property? Are taxes paid? Is there any documentation of your ownership and possession? Then you almost certainly do not have an adverse possession problem.

2. Unauthorized occupants — the real "squatter" case

This is someone occupying a property who never had a tenancy at all. A vacant house is broken into. A property in probate is occupied by someone who saw it was empty. Someone moves into a unit between tenancies.

Colorado provides an expedited process for removing unauthorized occupants who never had a landlord-tenant relationship with the owner. It is meaningfully faster than a standard eviction, precisely because the legislature recognized that treating a break-in as a tenancy dispute was absurd.

But it is still a legal process. You still go through the courts. You still do not remove anyone yourself.

3. Holdover tenants — the most common by far

A tenant whose lease ended but who has not left. Or an occupant who was allowed to stay informally. Or the tenant's partner or relative who remained after the tenant moved out.

These are not squatters, however much it feels like it. Once someone has been in lawful possession, ending that possession runs through the ordinary eviction process — notice, court, judgment, sheriff. Our guides to the Colorado eviction process and evicting a tenant with no lease cover this ground.

The category error here is expensive. Treating a holdover tenant as a trespasser — calling the police, changing locks — does not shortcut anything. It creates a second legal problem on top of the first.

The thing you must not do

Colorado prohibits self-help eviction, and the prohibition holds even against someone with no right to be there. Do not change the locks. Do not remove belongings. Do not shut off utilities. Do not have a conversation intended to intimidate.

The liability for self-help can substantially exceed whatever the occupant was costing you, and it converts a situation where you are clearly in the right into one where you are not. Owners who have been through this describe the same sequence: months of frustration, one impulsive afternoon, and a far worse position.

If the police will act on a genuine trespass, that is a legitimate route — but be aware that officers frequently and reasonably decline to referee anything that looks like a civil possession dispute. That is not obstruction; it is the correct call given what they can verify at the door.

Prevention, which is the only cheap part

• Do not leave property visibly vacant. Mail piling up, unmown grass and dark windows are the actual signal.
• Inspect regularly. A property nobody visits for three months is the one this happens to.
• Secure it properly between tenancies — locks changed, windows secured, alarm active.
• Have a local presence. A neighbor with a phone number, or a manager who drives past.
• Document ownership and possession — dated photographs, utility accounts, inspection records.
• Never let an informal occupancy drift. The friend of a tenant who stayed on, the relative who moved in "temporarily" — get it documented or ended while it is still easy.

Almost every genuine squatter case involves a property nobody was watching. That is the actual risk factor, and it is the one entirely within your control.
