Colorado’s Make My Day law has one of the most recognizable names in the state’s criminal code and is one of the least understood. The name suggests broad authority. The statute is considerably more specific. For anyone who has ever wondered exactly what the law permits, where it applies, and where it stops, the answer matters enormously because getting it wrong can result in a criminal charge even in a situation that began as self-defense in your own home.
What the Statute Actually Says
Colorado’s Make My Day law is codified at C.R.S. § 18-1-704.5, enacted in 1985. The statute opens with a declaration that the citizens of Colorado have a right to expect absolute safety within their own homes. That declaration reflects the law’s purpose, but the protection it provides is defined by specific legal requirements, not by that opening sentence alone.
Under § 18-1-704.5(2), an occupant of a dwelling is justified in using any degree of physical force, including deadly physical force, against another person when three conditions are all simultaneously present:
- Unlawful entry: The other person has made an unlawful entry into the dwelling.
- Intent to commit an additional crime: The occupant has a reasonable belief that the intruder has committed a crime in the dwelling in addition to the uninvited entry, or is committing or intends to commit a crime against a person or property in the dwelling.
- Perceived threat of force: The occupant reasonably believes the intruder might use any physical force, no matter how slight, against any occupant.
All three elements must be present at the same time. The absence of any one of them means the Make My Day statute does not apply, and the occupant’s use of force would be evaluated under Colorado’s general self-defense law at C.R.S. § 18-1-704 instead, which imposes meaningfully different and more demanding requirements.
The Three Elements in Plain Language
Unlawful entry means the person entered the dwelling without legal authority or permission to do so. They do not need to have forced a lock or broken a window. Walking through an unlocked door without invitation can constitute unlawful entry. But if the person has a lawful right to be present, the statute does not apply. A co-tenant, a person with a key and permission to enter, an invited guest, or a law enforcement officer with a valid warrant all have lawful authority to enter. The Make My Day law is not a tool for resolving disputes with people who have a legal right to be in the home.
Reasonable belief of an additional crime means the occupant must believe the intruder has committed, is committing, or intends to commit a crime inside the dwelling beyond simply the unauthorized entry itself. Unlawful entry alone is not enough. The occupant must have a basis to believe something more is happening or about to happen. This element is evaluated under a reasonable person standard: would a person in the same situation, with the same information, reasonably believe the intruder intended to commit a crime? It is an objective standard, not purely subjective. An occupant’s fear alone, without a reasonable basis grounded in observable facts, does not satisfy this element.
Reasonable belief of any physical force is where the Make My Day law’s standard differs most significantly from general self-defense law. Under § 18-1-704.5, the occupant need only reasonably believe the intruder might use any physical force, no matter how slight. This is a meaningfully lower bar than what general self-defense law requires. Under C.R.S. § 18-1-704, which governs situations outside the home, deadly force is only justified when the person reasonably believes it is necessary to prevent imminent death or serious bodily injury. The Make My Day standard does not require serious bodily injury or death to be threatened. Any physical force, however slight, is sufficient, provided the other two elements are also met.
The Immunity Protection
When all three elements are satisfied, § 18-1-704.5(3) provides immunity from criminal prosecution. The statute carries its own powerful civil immunity shield under § 18-1-704.5(4), which provides absolute civil immunity. This means that if the statutory requirements are satisfied, the occupant cannot be sued by the intruder or the intruder’s estate for injuries or death. Subsection (4) is the primary civil protection because it does not require proving the intruder was committing a felony specifically. Any secondary crime that meets the three-element test is sufficient to trigger it. The statute also works in tandem with C.R.S. § 13-80-119, which separately bars individuals from recovering damages sustained while committing a felony. This combination of criminal and civil immunity is among the strongest home defense protections in the country. Very few states provide both shields in a single statutory framework.
The law provides a unique mechanism for pre-trial immunity. Under People v. Guenther, 740 P.2d 971 (Colo. 1987), an occupant can request a special pre-trial hearing in which the defense must prove the statutory elements by a preponderance of the evidence, meaning it is more likely than not that the three conditions were met. If the defense meets that burden, the judge must dismiss the criminal charges before the case ever reaches a jury.
Crucially, if the judge denies the pre-trial motion, the protection is not lost. The Make My Day defense can still be raised as an affirmative defense at trial, at which point the burden shifts to the prosecution to disprove the elements beyond a reasonable doubt. This two-stage structure gives a defendant two separate opportunities to invoke the statute’s protections.
What Counts as a Dwelling
The statute applies inside a dwelling. Colorado law defines a dwelling broadly as any building or structure that is used or intended for use as a habitation. The definition is not limited to traditional houses. Apartments qualify. Mobile homes qualify. Hotel rooms and extended-stay accommodations where a person is currently residing qualify. An RV used as a primary residence qualifies.
The statute specifically excludes any place of habitation in a detention facility under a 2016 amendment codified at § 18-1-704.5(5). A person incarcerated in a jail or prison cannot invoke the Make My Day law against another incarcerated person.
The attached garage question is one the courts have explicitly clarified. In People v. Jiminez, the Colorado Supreme Court established that an attached garage is structurally and functionally integrated into a residence and is therefore legally treated as part of the dwelling, qualifying for Make My Day protections. Courts draw a strict line at non-integrated spaces. In People v. Cushinberry, the Colorado Court of Appeals held that common areas of an apartment building, such as shared hallways and stairwells, do not qualify as a dwelling under the statute. A detached garage, shed, workshop, or other outbuilding that is not structurally integrated into the residence falls outside the Make My Day statute’s coverage and must be analyzed under the general self-defense statute instead.
Where the Law Does Not Apply
This is where the most common misunderstandings arise.
The Make My Day law does not apply outside the dwelling. Your front porch, backyard, driveway, and detached structures are all outside the statute’s protection. If an intruder has not yet entered the dwelling, or a confrontation begins and remains entirely outside, the Make My Day statute does not apply regardless of what you believe the person intends to do.
The Make My Day law does not authorize deadly force to protect property alone. Someone stealing from your yard or driveway is committing a property crime, but that theft, occurring outside the dwelling, does not trigger § 18-1-704.5. The statute requires that the crime the occupant believes the intruder intends to commit be inside the dwelling, and it requires a belief that the intruder might use physical force against an occupant. Property protection alone does not satisfy those elements.
The Make My Day law does not apply to lawful occupants. A roommate who has a legal right to be in the apartment, a family member who lives in the home, or a person who was invited and has not been clearly told to leave has not made an unlawful entry. The statute is designed to protect occupants against uninvited intruders, not to authorize force against people who have a legitimate presence in the home.
The Make My Day law does not eliminate the requirement of reasonable belief. The statute is not a license to shoot first without any factual basis for believing an intruder intends to commit a crime and might use force. Reasonableness is an objective standard reviewed by courts and juries. A use of force that turns out to have been based on a mistake, poor identification in low light, or a misread situation may not meet the statutory standard even when the occupant acted out of genuine fear.
How It Differs from Stand Your Ground
| Feature | General Self-Defense (C.R.S. § 18-1-704) | Make My Day Law (C.R.S. § 18-1-704.5) |
|---|---|---|
| Location | Anywhere: public spaces, vehicles, yards | Strictly inside a dwelling |
| Duty to retreat | No (established by Colorado case law) | No |
| Threshold for deadly force | Reasonable fear of imminent death or serious bodily injury | Reasonable belief intruder might use any force, no matter how slight |
| Primary shield | Affirmative defense argued at trial | Pre-trial immunity; basis for case dismissal before trial |
These two concepts are frequently conflated, but they are distinct. Stand your ground refers to the elimination of a duty to retreat before using force in self-defense, even in public spaces. Colorado courts have long held that Colorado does not impose a duty to retreat in self-defense situations generally, even outside the home, as a matter of case law rather than explicit statute.
The Make My Day law is Colorado’s castle doctrine, which is a narrower and more specific protection applicable only inside a dwelling. It provides a lower threshold for the use of deadly force than general self-defense law within that specific location. The two concepts address different aspects of self-defense law, and neither one means that force can be used without meeting the applicable legal elements.
What Happens When the Law Is Invoked
When a person uses force against an intruder and claims protection under § 18-1-704.5, law enforcement will investigate the facts to determine whether all three statutory elements were present at the time. That investigation will include examination of the manner of entry, physical evidence at the scene, statements from the occupant and any witnesses, the relationship between the occupant and the person who was injured or killed, and whether the use of force was consistent with what a reasonable person in the same situation would have done.
A claim of Make My Day protection does not end the investigation and does not automatically prevent charges from being filed. Law enforcement and prosecutors evaluate the facts against the statutory elements, and those evaluations are not always consistent with how the occupant understood the situation. A case that appears straightforward to the person who used force can raise significant legal questions when the evidence is examined in detail.
