Stand your ground means you have no legal duty to retreat before defending yourself with force. Colorado has no statute carrying that name. Even so, Colorado courts have held for more than a century that a person who did not start the confrontation and is lawfully present may hold their position rather than flee.
That principle works alongside the Make My Day law, which gives occupants far stronger protection inside a dwelling. If officers or prosecutors are now questioning force you believed was justified, what you say and preserve in the first days matters.

Stand your ground is a rule about retreat. It does not decide whether force was reasonable, whether the threat was real, or how much force the law allowed.
It answers one narrower question: Must a person try to escape before using force that would otherwise be lawful?
States take one of the following approaches:
In a duty-to-retreat state, a prosecutor can argue that an available escape route made the force unnecessary. Colorado does not permit that argument against a person who was not the aggressor. Our courts have recognized that a defendant may hold their position and meet force with proportional force.
The castle doctrine is narrower and applies only inside a home. Stand your ground applies anywhere a person is lawfully present, including a sidewalk, parking lot, or workplace. Colorado protects both, though through different legal routes.
Functionally, yes. There is no statute called stand your ground anywhere in Title 18 of the Colorado Revised Statutes, and the phrase appears nowhere in the criminal code. What exists instead is a line of Colorado Supreme Court decisions producing the same practical result.
A defendant asserting self-defense who was not the initial aggressor is entitled to a jury instruction stating there is no duty to retreat. The Colorado Supreme Court confirmed that rule in Idrogo v. People, 818 P.2d 752 (Colo. 1991), and again in Cassels v. People, 92 P.3d 951 (Colo. 2004).
The protection reaches further than many people expect. In People v. Toler, 9 P.3d 341 (Colo. 2000), the court held that even a trespasser has no obligation to retreat before using force, provided that person was not the initial aggressor.
No-retreat status is not immunity. Officers may still arrest, prosecutors may still file charges, and a jury may still reject the claim. Colorado also draws a hard line at property: The absence of a retreat requirement never converts a property dispute into grounds for deadly force.
Removing the retreat question also leaves every other element untouched. Whether the threat was imminent, whether the belief was objectively reasonable, and whether the amount of force matched the danger all remain contested issues that a prosecutor can build a case around.
Several statutes can govern a single incident, and which one applies often turns on where the person was standing and what they were protecting.
This is the central self-defense provision. Under C.R.S. § 18-1-704, a person may use physical force against another when they reasonably believe unlawful physical force is being used or is imminent. The degree of force must be what the person reasonably believes necessary for that purpose.
Reasonableness is judged objectively. A sincere belief is not enough if an objectively reasonable person in the same circumstances would not have shared it.
Enacted in 1985, C.R.S. § 18-1-704.5 covers force used against someone who has made an unlawful entry into a dwelling. Many people know it as the Colorado make my day law or the castle doctrine, and the General Assembly opened the section by declaring that residents have a right to expect safety within their own homes.
It is the strongest use-of-force protection in Colorado law because it grants immunity rather than merely supplying a defense at trial.
A person in possession or control of a building or property may use reasonable and appropriate force to prevent or stop an unlawful trespass. Under C.R.S. § 18-1-705, deadly force is available in only two situations: Defense of a person under § 18-1-704, or a reasonable belief that the trespasser is attempting first-degree arson.
Force to protect property is far more limited. C.R.S. § 18-1-706 permits reasonable and appropriate force to stop theft, criminal mischief, or criminal tampering. Deadly physical force is never authorized to protect property alone, and a firearm counts as deadly physical force whether or not it is fired.
Criminal exposure is not the only concern after a use of force. C.R.S. § 13-80-119 bars recovery of damages sustained during the commission of a felony or during immediate flight from one, subject to the conditions in that section.
Deadly physical force carries a higher threshold than ordinary force. Section 18-1-704(2) permits it only when a person reasonably believes a lesser degree of force would be inadequate and one of the following circumstances exists:
Both conditions must be satisfied. Meeting one of the listed circumstances does not help if a lesser degree of force would have stopped the threat.
Section 18-1-704(3) removes the justification entirely in specific situations. A person is not justified in using physical force when:
The final exception was added by Senate Bill 20-221 and took effect on July 13, 2020. It forecloses what was once argued as a panic defense, including situations involving an unwanted nonforcible romantic or sexual advance.
The initial aggressor is whoever started the physical conflict by using or threatening imminent unlawful force, as the Colorado Supreme Court explained in Castillo v. People, 2018 CO 62. This status is not permanent. An aggressor who withdraws and clearly communicates that withdrawal regains the right to defend themselves if the other person keeps attacking.
Mutual combat strips away the defense, but Colorado courts apply it narrowly. Without a clear agreement to fight drawn from the evidence, the jury should not receive a mutual combat instruction at all. Kaufman v. People, 202 P.3d 542 (Colo. 2009), requires a definite agreement before that limitation applies.
Section 18-1-704.5 asks a different set of questions than ordinary self-defense. An occupant is justified in using any degree of force, including deadly force, when an intruder makes an unlawful entry, the occupant reasonably believes that person committed or intends a crime beyond the entry itself, and the occupant reasonably believes that person might use any physical force, no matter how slight, against any occupant.
Note how low that last threshold sits. The statute does not require a weapon, a serious threat, or an injury.
Boundaries matter more than most people realize, and appellate courts continue to refine them. An outdoor doorstep is not part of a dwelling, so force used against someone standing there falls outside the statute under People v. Howell, 2024 CO 42. A shared apartment basement accessible to all tenants can qualify as part of a tenant's dwelling under People v. Rau, 2022 CO 3.
Entry must also be knowing and criminal, not accidental or mistaken. That requirement comes from People v. McNeese, 892 P.2d 304 (Colo. 1995).
The statute provides immunity from criminal prosecution and from civil liability for injuries or death. A trial court may dismiss charges before trial, though the defendant carries the burden of establishing immunity by a preponderance of the evidence at that hearing. If the pretrial motion is denied, the issue can still be raised at trial.
Cases involving justified force are frequently won or lost on the record created in the first 48 hours. Consider the following sequence:
Adrenaline distorts memory and perception of time. An account given at the scene may contain errors that a prosecutor later characterizes as inconsistencies.
Our attorneys handle assault, domestic violence, weapons, and homicide matters where the central question is whether force was legally justified. Phones are answered 24 hours a day, which matters because these cases move quickly.
The prosecution frames these incidents around what the accused person did. Our team works to reconstruct what that person reasonably perceived, using scene photographs, medical records, prior threats, 911 audio, and witness accounts gathered before memories fade.
Timing drives much of that work. Surveillance video is frequently overwritten within days, and injuries fade, so we move early to request footage and document physical evidence while it still exists.
Where the facts support it, § 18-1-704.5 allows a motion to dismiss before a jury is ever seated. We evaluate whether the entry, the dwelling boundary, and the occupant's beliefs meet the statutory elements, and we advise clients candidly when they do not.
Not by that name. The Colorado legislature has never passed a statute using the phrase, though the National Conference of State Legislatures groups Colorado among states with no duty to retreat based on case law.
Generally, no. A person who is lawfully present and was not the initial aggressor has no obligation to retreat before using force that is otherwise reasonable and necessary.
Yes. Officers may arrest whenever they have probable cause, and self-defense is usually resolved later by a judge or jury rather than at the scene.
No. Section 18-1-706 permits only reasonable and appropriate force for property, and deadly force becomes lawful only if the situation independently threatens a person.
Often it does not. An outdoor doorstep has been held not to be part of a dwelling, and common areas of apartment buildings generally fall outside the statute, which makes the exact location of the confrontation critical.
Colorado's stand your ground protections are real, but they are decided case by case on facts that investigators start collecting immediately. The sooner your account, your injuries, and the scene itself are documented, the stronger the record becomes.
