Colorado’s Make My Day law, codified at CRS 18-1-704.5, lets any occupant of a dwelling use deadly force against an intruder, and shields that occupant from both criminal prosecution and civil liability, when three conditions are all met at the same time: the intruder entered unlawfully and uninvited, the occupant reasonably believed the intruder had committed, was committing, or intended to commit a crime beyond the entry itself, and the occupant reasonably believed the intruder might use physical force, no matter how slight, against anyone in the dwelling.1Justia. Colorado Revised Statutes Title 18 Section 18-1-704.5 – Use of Deadly Physical Force Against an Intruder Miss any one of the three and the immunity disappears.
The Three Conditions, Spelled Out
The statute is narrower than its reputation. All three elements have to be present together.
First, the entry must be unlawful and uninvited. Someone you let in has not entered unlawfully, even if they later turn on you. A co-occupant or someone with a key and permission to be there has not made an uninvited entry either.
Second, you must reasonably believe the intruder has committed, is committing, or intends to commit a crime inside the dwelling on top of the trespass itself. Breaking in, standing alone, is not enough to trigger the statute.
Third, you must reasonably believe the intruder might use physical force against any occupant. This is the element that makes Make My Day unusual. The threshold is “any physical force, no matter how slight.”1Justia. Colorado Revised Statutes Title 18 Section 18-1-704.5 – Use of Deadly Physical Force Against an Intruder You don’t have to believe you were about to be seriously injured or killed. You just have to have a reasonable basis to think the intruder might use some force against someone in the home.
“Reasonable belief” still carries weight. You have to be able to articulate why you believed each element existed, and a court will test those beliefs against what a reasonable person in your position would have thought.
Who Counts as an Occupant, and What Counts as a Dwelling
Any occupant can invoke the law, not just the owner or the person on the lease. A roommate, a family member, or an overnight guest lawfully staying in the home qualifies. A neighbor who runs into your house to help does not; they are not an occupant, and the statute does not cover them.1Justia. Colorado Revised Statutes Title 18 Section 18-1-704.5 – Use of Deadly Physical Force Against an Intruder
The statute defines “dwelling” only by what it excludes: a place of habitation in a detention facility.1Justia. Colorado Revised Statutes Title 18 Section 18-1-704.5 – Use of Deadly Physical Force Against an Intruder Colorado courts have treated houses, apartments, mobile homes, and hotel or motel rooms used as temporary residences as dwellings. Shared spaces in apartment complexes, like hallways, stairwells, and lobbies, have been held outside the definition. A front porch, a driveway, a detached garage, a parking lot, a vehicle, or a business is almost certainly outside the law’s protection as well. For anything that happens in those places, Colorado’s general self-defense statute applies, with its higher threshold for deadly force.
What the Immunity Actually Covers
When the three conditions are met, subsection (3) bars criminal prosecution and subsection (4) bars civil liability for any injury or death caused by the force.1Justia. Colorado Revised Statutes Title 18 Section 18-1-704.5 – Use of Deadly Physical Force Against an Intruder This is true immunity, not an affirmative defense you raise at trial. It is a shield that keeps the trial from happening.
The civil piece matters. In many states with castle doctrine laws, a homeowner can beat a criminal charge and still lose a wrongful death suit filed by the intruder’s family. Under Make My Day, if the force qualifies, neither a prosecutor nor a plaintiff’s lawyer can proceed. The qualifier is the whole game: if any of the three conditions was missing, both the criminal and civil immunity are gone.
Situations Where the Law Will Not Protect You
Most failures of Make My Day protection come from a mismatch with the first condition. The entry wasn’t actually unlawful and uninvited.
- A guest you invited in who later becomes aggressive did not enter unlawfully. Any force you use has to be justified under the general self-defense statute instead.
- A co-occupant, spouse, or someone with a key and permission to enter has not made an uninvited entry, even during a violent fight. Make My Day does not apply to domestic disputes of this kind.
- Force used outside the dwelling, including chasing someone into the yard, the driveway, or the street, happens outside the statute’s reach.
- If you can’t explain why you believed the intruder intended to commit a crime inside, or why you believed they might use force against an occupant, you haven’t satisfied the statute. A general fear of crime in the area is not enough.
Exposure If the Statute Does Not Apply
Without the immunity, an occupant who injures or kills someone faces the same criminal and civil exposure as anyone else who used unjustified force. Prosecutors can file second-degree murder, a class 2 felony with a presumptive sentencing range of 8 to 24 years.2Justia. Colorado Revised Statutes Title 18 Section 18-3-103 – Murder in the Second Degree A killing in a sudden heat of passion provoked by the intruder drops to a class 3 felony. Reckless killings can be charged as manslaughter, a class 4 felony.3Justia. Colorado Revised Statutes Title 18 Section 18-3-104 – Manslaughter
On the civil side, the intruder or their family can bring a wrongful death action under CRS 13-21-202, and a surviving intruder can sue for personal injury.4Justia. Colorado Revised Statutes Title 13 Section 13-21-202 – Wrongful Death Civil cases use a lower standard of proof than criminal cases, so an acquittal does not insulate you from a civil judgment.
How It Differs From General Self-Defense
Colorado has two layers of self-defense law, and they are easy to confuse. CRS 18-1-704 is the general statute and applies everywhere, including inside your home. CRS 18-1-704.5 is Make My Day, and it adds protection that only applies inside a dwelling.
Under the general statute, you can use deadly force only when you reasonably believe a lesser degree of force would be inadequate and you face imminent danger of being killed or seriously injured.5Justia. Colorado Revised Statutes Title 18 Section 18-1-704 – Use of Physical Force in Defense of a Person That is a high bar, and whether you cleared it gets decided by a jury after the fact.
Make My Day replaces “imminent danger of death or serious injury” with “any physical force, no matter how slight,” and replaces a trial defense with pretrial immunity. If the three conditions line up, the case ends before prosecution begins. If they don’t, you are back under the general statute, with its higher threshold and no immunity shield.
What to Do After a Home Defense Incident
What happens in the hours after the shooting often decides whether you keep the law’s protection. Officers will investigate every use of deadly force, and anything you say becomes evidence.
Call 911 right away and ask for medical help if anyone is hurt. When officers arrive, identify yourself and follow basic instructions, but do not give a detailed account of what happened before you have a lawyer. Adrenaline distorts memory, and a wrong detail in an early statement can be used to attack your credibility later. Tell officers you were in fear for your safety, that you will cooperate, and that you want counsel before making a statement.
Leave the scene alone. Don’t move or handle anything. If there is damage from a forced entry, don’t repair it until it has been documented. Photos of broken locks, shattered glass, and interior damage all support the unlawful-entry element.
Hire a lawyer with self-defense experience as soon as you can, even if no charges have been filed. Charging decisions can take weeks or months. A lawyer can deal with investigators on your behalf, preserve favorable evidence, and position you for a pretrial immunity ruling if a case is brought.
