Colorado Self-Defense Laws: Stand Your Ground & Make My Day (2026)

Colorado does not have a stand-your-ground statute, but Colorado courts have consistently held that a non-aggressor has no legal duty to retreat before using force in self-defense. Inside a dwelling, the "Make My Day" law (C.R.S. 18-1-704.5) goes further: it grants an occupant both criminal and civil immunity for using any degree of force, including deadly force, against someone who unlawfully enters and whom the occupant reasonably believes may commit a crime and use physical force. General self-defense for all other situations is governed by C.R.S. 18-1-704.

Does Colorado Have a Stand Your Ground Law?

Colorado has no statute titled "stand your ground" and no statute that uses that phrase. The legislature has never enacted a freestanding no-duty-to-retreat law comparable to the statutes in Florida or Texas.

However, Colorado courts have interpreted the general self-defense statute, C.R.S. 18-1-704, to impose no duty to retreat before using force. In People v. Toler, the Colorado Supreme Court confirmed that a non-aggressor who is lawfully present and facing unlawful force is not required to retreat before defending themselves. The right to stand one's ground is therefore a matter of case law, not statute, in Colorado.

The practical result is that Colorado functions as a no-duty-to-retreat state in public spaces. A person who is not the aggressor, is not engaged in a mutual combat agreement, and has not provoked the confrontation may use reasonable force without first attempting to flee.

The distinction from a statutory stand-your-ground state matters in one key way: because the rule comes from case law rather than a statute, there is no codified immunity hearing procedure before trial for an ordinary self-defense claim. A defendant relying on C.R.S. 18-1-704 asserts self-defense as a justification at trial rather than at a pre-trial immunity hearing.

The Make My Day law is the exception. A dwelling occupant claiming immunity under C.R.S. 18-1-704.5 does have a pretrial motion available, and must use it. That procedure is described below.

The Make My Day Law (C.R.S. 18-1-704.5)

Colorado's Make My Day law is one of the broadest dwelling-protection statutes in the United States. Enacted in 1985, it reflects the legislative judgment that Coloradans deserve "absolute safety within their own homes."

What the Law Covers

C.R.S. 18-1-704.5 authorizes a dwelling occupant to use "any degree of physical force, including deadly physical force," against an intruder who has made an unlawful entry, when the occupant reasonably believes two conditions are met:

1. The intruder has committed or intends to commit a crime in addition to the unauthorized entry itself.
2. The intruder might use any physical force against any occupant.

The threshold is lower than the general deadly-force standard under C.R.S. 18-1-704. Under Make My Day, the occupant does not need to believe death or great bodily injury is imminent. The occupant only needs a reasonable belief that the intruder might use any physical force and might commit some crime. This makes the Make My Day law a significantly more protective standard for homeowners than ordinary self-defense law.

Criminal and Civil Immunity

Make My Day provides two separate layers of legal protection:

Criminal immunity: An occupant who uses force in accordance with C.R.S. 18-1-704.5 is immune from criminal prosecution, which is broader than a defense that merely blocks a conviction. It is not a bar on charging, though. Colorado courts read the statute as authorizing a judge to dismiss a prosecution at the pretrial stage, and have specifically held that this does not infringe the prosecution's discretion to file charges in the first place.

Civil immunity: The occupant is also immune from civil liability for injuries or death resulting from the authorized use of force. This means the intruder or the intruder's estate cannot recover from the occupant in civil court for damages.

Both forms of immunity apply together. When the conditions of Make My Day are satisfied and the occupant establishes them, the case ends in dismissal rather than a trial. Getting there is a procedural step the occupant has to take, described below.

Dwelling-Only Scope

The Make My Day law is strictly limited to a "dwelling." C.R.S. 18-1-704.5(5) does not itself define that word. It only carves one thing out, providing that a dwelling does not include any place of habitation in a detention facility, and the cross-reference it gives to C.R.S. 18-8-211(4) supplies the definition of "detention facility," not the definition of "dwelling." The controlling definition sits in the Criminal Code's general definitions at C.R.S. 18-1-901(3)(g): a dwelling is "a building which is used, intended to be used, or usually used by a person for habitation." In plain terms, a place where people live: a house, apartment, condominium, or similar residential structure.

Make My Day does not apply to:

• Vehicles, including cars, trucks, and RVs parked outside the dwelling
• The yard, driveway, or porch surrounding the home
• Businesses, even if the business owner is present
• A second home or vacation property when the occupant is not present (presence is required)

If a confrontation occurs in any of these locations, the occupant must rely on the general self-defense statute, C.R.S. 18-1-704, not the Make My Day law.

When Deadly Force Is Justified Under C.R.S. 18-1-704

Outside the dwelling context covered by Make My Day, deadly force in Colorado is governed by C.R.S. 18-1-704. Under that statute, a person may use physical force against another when they reasonably believe it is necessary to defend themselves or a third person from the use or imminent use of unlawful physical force.

Deadly physical force is justified only when the person reasonably believes a lesser degree of force is inadequate, and at least one of the following conditions exists:

• The person reasonably believes they or another person face imminent danger of being killed or of receiving great bodily injury.
• The other person is using or reasonably appears about to use physical force against an occupant of a dwelling or business establishment while committing or attempting to commit burglary.
• The other person is committing or about to commit kidnapping, robbery, sexual assault, or assault.

The standard is objective reasonableness: a jury evaluates whether a reasonable person in the same circumstances would have held the same belief. Subjective fear, standing alone, is not enough if a reasonable person would not have shared that fear.

Civil Exposure Outside the Dwelling

Make My Day's civil immunity stops at the dwelling, but it is not the only Colorado statute that limits civil suits over defensive force. C.R.S. 13-80-119 bars a person from recovering damages sustained during the commission of, or during immediate flight from, an act defined as a felony. The official code cross-references it by name directly under both C.R.S. 18-1-704 and C.R.S. 18-1-704.5, and nothing in it is limited to the home.

In two situations the statute is mandatory. Where the person bringing the suit was convicted of the felony or adjudicated a delinquent for it, and where the person being sued was found not guilty of criminal charges for causing the injuries, the court "shall dismiss the action for damages and award attorney fees and costs" to the person who was sued. The statute carves out damage caused by the "willful and deliberate act" of another person, but that carve-out is itself switched off where the person who caused the injuries acted on a reasonable belief that physical force was reasonable and appropriate to prevent injury to themselves or others, or to prevent the commission of a felony. In other cases, whether the injured person was committing a felony goes to the jury on a preponderance standard, with dismissal and fees following a finding that they were.

This is narrower than Make My Day immunity, and it is worth being precise about why. It turns on what the person suing was doing, not simply on whether the defensive force was lawful. If the person injured was not committing or fleeing a felony, C.R.S. 13-80-119 does not apply at all, and an ordinary civil case proceeds on its facts.

Criminal and Civil Immunity Under Make My Day

Because the immunity provisions of C.R.S. 18-1-704.5 are explicit in the statute, Colorado courts have applied them broadly within the dwelling. The Colorado Court of Appeals has held that when the facts satisfy Make My Day, both criminal prosecution and civil suit are barred.

For the immunity to attach, the occupant must establish:

1. There was an unlawful entry into the dwelling.
2. The occupant had a reasonable belief that the intruder had committed, was committing, or intended to commit a crime in addition to the unlawful entry.
3. The occupant had a reasonable belief that the intruder might use any physical force against any occupant.

All three elements must be present. An occupant who uses force against a trespasser who made no threatening gesture and showed no indication of committing any further crime may not qualify for Make My Day immunity.

How the Immunity Is Actually Raised

Make My Day immunity does not operate on its own, and it is a mistake to assume that a qualifying set of facts means no case ever gets filed. A prosecutor may still bring charges, and the Colorado Supreme Court has held that the statute's pretrial dismissal mechanism does not infringe the prosecution's discretion to file them (People v. Guenther, 740 P.2d 971 (Colo. 1987)).

The occupant carries the burden. To obtain dismissal, the occupant must raise the immunity in a pretrial motion to dismiss and establish entitlement to it by a preponderance of the evidence (People v. McNeese, 892 P.2d 304 (Colo. 1995)). That is a lower burden than the state's burden at trial, but it is the occupant's to carry, and motions do get denied on the ground that it was not met.

If the pretrial motion is denied, the prosecution continues and the occupant may raise the statute again as an affirmative defense at trial, where the burden of proof generally applicable to affirmative defenses applies (People v. Malczewski, 744 P.2d 62 (Colo. 1987)). A denial at the pretrial stage is not a final judgment and cannot be appealed as of right before trial, although the Colorado Supreme Court has said a defendant may seek review beforehand under C.A.R. 21 (Wood v. People, 255 P.3d 1136 (Colo. 2011)).

The practical takeaway is that Make My Day is a strong protection but not an automatic one. Someone who uses force against an intruder should expect an investigation, should expect that charges are possible, and should expect to have to prove the statute's elements before a judge.

When Self-Defense Fails in Colorado

Colorado law identifies several situations in which self-defense is not available as a justification.

Initial aggressor: A person who initiates a physical confrontation cannot claim self-defense unless they clearly communicate their withdrawal from the fight and the other person continues to threaten or use force.

Provocation with intent to harm: If a person provokes another with the specific intent to create a pretext for using force against them, self-defense is unavailable.

Mutual combat: Participants in a fight that is the product of a combat by agreement not specifically authorized by law cannot claim self-defense. Unlike the initial-aggressor bar, C.R.S. 18-1-704(3)(c) contains no withdrawal exception for combat by agreement; the withdraw-and-communicate exception applies only to the initial-aggressor bar under (3)(b).

Not inside a dwelling: The Make My Day immunity does not apply outside the dwelling. A homeowner who pursues an intruder into the yard or street, or who confronts someone in the driveway, must satisfy the general deadly-force standard of C.R.S. 18-1-704 instead.

Excessive force: Force that far exceeds what a reasonable person would use in the circumstances can defeat a self-defense claim even when some level of force was initially justified.

Gender-identity provocation bar: Colorado expressly prohibits claiming self-defense based on discovering another person's gender identity, gender expression, or sexual orientation. This provision was added to C.R.S. 18-1-704 by the legislature.
