Purpose to Commit a Crime
Entry into a protected place becomes burglary only when the actor carries a particular state of mind across the threshold. Section 221.1(1) supplies that requirement in the words "with purpose to commit a crime therein."1 Those words separate burglary from ordinary trespass, because an unlicensed entry with no design on anything inside is the lesser wrong, and a later section compares the two offenses directly. The phrase also packs more than one question into a few words, which is why this section is divided into three parts below.
The word "purpose" is a defined culpability term (a label for the actor's required state of mind) in the Code, and the definition decides how much the prosecution must prove. Under § 2.02(2)(a)(i), an actor acts purposely toward a material element of an offense when it is the actor's conscious object to engage in conduct of that nature or to cause such a result.2 Purpose is the Code's most demanding level of culpability, because it asks what the actor was trying to accomplish, a narrower question than what the actor was aware might happen. For burglary, then, committing a crime inside must be the objective the actor holds when going in. Awareness that a crime is likely to follow does not satisfy that definition.
The reason the Code places so much weight on this element appears when burglary is viewed as an early-stage offense. The offense is complete at entry, before any theft, assault, or damage has occurred inside, so the only act the statute requires is the crossing of a threshold. Because that act is so slight, the actor's design is what justifies calling the conduct burglary and punishing it more heavily than a bare unlicensed entry. Burglary can be understood as a form of attempt liability with a lightened act requirement, since the law treats a person who enters private property with a criminal design as having moved from preparation into commission, without the more demanding step that attempt law ordinarily requires.3 Burglary also generally does not merge into the completed target offense, and its punishment is usually far greater than that of many crimes an intruder might commit inside.4 The attempt comparison explains the shape of the element and does not supply a test for exam problems. What it does show is that, because the design alone carries the offense, three features of that design must be pinned down: when it must exist, what it must aim at, and where the aimed-at crime must occur.
The subsections below take the three questions in the statute's order, beginning with the moment at which the purpose must exist.
Purpose at the Time of Entry
The first question inside the purpose element is when the purpose must exist, and the statute's own sentence structure answers it. Section 221.1(1) makes a person guilty of burglary who "enters" a protected place "with purpose to commit a crime therein," so the purpose phrase modifies the act of entering and ties the mental state to that one moment.6 The inquiry is therefore what the actor was trying to accomplish while crossing the threshold. A design that forms afterward, once the actor is already inside, is a separate mental state attached to a later moment, and it cannot reach back and change what the entry was. This purpose at the time of entry requirement is the first of the three questions that frame the purpose element.
The reason follows from what the offense punishes. Burglary is complete at entry, before any theft or assault has occurred, and the only thing separating the entry from an ordinary unlicensed intrusion is the actor's design. Because that design is what justifies treating so slight an act as a serious offense, it has to be present when the act occurs.7 An actor who came in for some other reason, even an innocent one, and only later decided to take something did not cross the threshold in order to commit a crime. That actor answers for the later crime itself, but the burglary charge, whose punishment is usually far greater than that of many crimes an intruder might commit inside, is reserved for the person who came in with the crime already in mind.8
A Kansas appellate decision on aggravated burglary illustrates the same timing idea under that state's own statute, and only the idea carries over to the Code. The court stated that the specific intent must exist at the time of the unauthorized entry.9 The court accepted that the defendant's possession of methamphetamine inside the residence was wilful and wanton, yet it held the evidence insufficient on the theory that he entered to possess the drugs, because he did not enter with the purpose of possessing them.10 The assault theory against the same defendant fared differently. He kicked in the door and entered with a knife in his hand to use against any occupant who approached, and upon entering he immediately searched for and acquired a much larger knife, which was enough to show an entry with intent to commit aggravated assault.11 The two theories rested on one intrusion by one person, so the variable that decided them was whether the design to commit the named crime existed at the moment of entry. Kansas speaks of an intended felony, while § 221.1(1) asks for purpose to commit "a crime," a difference that the next subsection develops.12
The timing rule governs the purpose itself and leaves open what evidence may prove it. A prosecutor has no direct access to the actor's mind at the threshold, so the purpose is ordinarily inferred from what the actor did at and around the entry, and the facts the Kansas court recited (a forced door, a knife already in hand, an immediate search for a larger one) all cluster around the moment of entry.13 Conduct just after entry can therefore show what the actor meant on entering. What it cannot do is supply a purpose the actor did not yet have, which is why a crime committed inside does not by itself establish a purpose held at entry. A theft found inside shows that the actor was willing to steal at some point, and the element asks about a particular point.
The Kansas decision also teaches a second point, about charges that name more than one intended crime. The jury there had specifically found that the defendant held two intents when he entered, the possession of methamphetamine and the commission of an aggravated assault. The first was unsupported and the second was supported, and the conviction was affirmed because the State was not required to prove more than one of the alternatively charged intents.15 The court stressed that the case did not involve a general verdict, so there was no room to speculate that the jury had convicted on an intent the evidence failed to support.16 That result follows from the element itself. Burglary asks whether the actor entered with purpose to commit a crime, and the identity of the crime is only the means by which the element is met, so one supported purpose held at entry fully satisfies it and a second, unsupported purpose adds nothing the State needed.
Timing works differently under statutes that reach a person who enters or remains with the required intent. Many modern burglary statutes are drafted that way, and under them the intent need exist only when the defendant unlawfully remains, which captures the bank customer who enters lawfully, hides until closing, and then takes the bank's money.17 Section 221.1(1) as printed speaks only of entering, so under its text the moment that counts is the crossing of the threshold, and a question that adds the word remains changes the timing analysis.18 Purpose at entry is also necessary without being sufficient. A shoplifter whose intent to steal existed before walking into an open store is not a burglar, because the Code also requires an entry that is unprivileged, an element a later section takes up.19
Any Crime Qualifies
With the timing of the purpose fixed at the moment of entry, the next question is what the actor must have meant to do once inside. Section 221.1(1) answers with the phrase "purpose to commit a crime therein," and the object of that phrase is a bare noun.21 The text does not say a felony, a theft, or a violent offense, so an intended misdemeanor, an intended act of vandalism, and an intended assault each fill the slot equally well. The preceding subsection noted that the Kansas statute asks about an intended felony, and § 221.1(1) contains no comparable limit. The element therefore asks only whether the actor entered with a criminal design of some kind, and the grade or type of the crime designed is not part of the inquiry. The usual error is importing a felony, theft, or violence requirement from everyday usage or from another statute, and the rest of this subsection explains why the Code's wording resists that move. In short, any crime qualifies as the target.
The common-law entry rule shows what the Code's wording leaves behind. In explaining when the insertion of a tool counts as an entry, that rule asks whether the defendant used the tool for the purpose of committing the felony inside the dwelling, so its description of both the intended offense and the place is narrower than the Code's.22 Under that formulation the purpose is measured against a felony. The Code replaces both references: it speaks of a crime, and it protects buildings and occupied structures rather than dwellings alone.23 The broader wording follows from what the purpose element is for. The element identifies the intruder whose entry carries a criminal design, and that design is equally present whether the intended act is a petty theft or a robbery. A felony limit would also tie guilt to how the intended offense happens to be graded, and grading often turns on facts, such as the value of what is taken, that an intruder may not know at the threshold. Defining the target as any crime keeps the offense focused on the intruder's design, without a list of preferred offenses.
The Code is not alone in this breadth. Minnesota's burglary statute likewise does not require that the intended crime be a felony or a violent offense, and that pattern is typical of many modern burglary statutes.24 Connecticut's third-degree burglary provision, Conn. Gen. Stat. § 53a-103, reaches a person who "enter[s] or remain[s] unlawfully in a building with intent to commit a crime therein."25 That wording differs from § 221.1(1) in covering unlawful remaining, which bears on timing as the previous subsection explained, but on the target it matches the Code, because the intended act is described only as a crime.
The two intruders differ in one respect: whether either held a criminal design when crossing the threshold. Pia's design was small, and its size did not matter. The element sorts intruders by whether any criminal design was present, and the seriousness of the crime designed does not enter the sorting. Quinn's lawful-seeming plan to stay warm gave the element nothing to work with, which is why the same closed store and the same unlicensed entry produce a burglary for one actor and, at most, a trespass for the other.
The breadth has a cost that deserves candid mention. Because the offense is complete on entry with the required purpose, the burglary label attaches whatever crime was intended, so an entry meant to commit a minor offense can carry burglary-level consequences. Critics point out that the punishment for burglary is usually far greater than the punishment for most of the offenses an intruder might actually commit inside the structure, and some argue that modern attempt law would tie punishment more closely to the gravity of the offense that was intended.27 The Code does not leave the matter ungraded, since § 221.1(2) makes burglary a felony of the second degree when it is perpetrated in the dwelling of another at night, or when the actor does certain things in the course of the offense, and grading is a subject for a separate section.28 This tension is real, and the purpose element itself does not resolve it. The proportionality concern is a reason critics offer for reforming the offense, and it is not a limit written into the element, so an answer applies the broad wording as it stands.
Once the target is understood to be any crime, the remaining purpose question is where that crime must be committed.
A Crime Committed Therein
With the target of the purpose defined as any crime, the remaining question is where that crime must be committed, and the answer sits in the last word of the element. Section 221.1(1) requires "purpose to commit a crime therein," and "therein" refers back to the building, occupied structure, or secured portion the actor has just entered.30 The crime the actor means to commit must therefore be one that will occur inside the premises once the actor has crossed the threshold, and it must be a crime beyond the unlicensed entry itself. The text does not announce that second feature in so many words, yet it follows from how burglary relates to the trespass offense, and that relationship explains why the word matters. This is the requirement of a crime committed therein, the third question inside the purpose element after timing and breadth.
The structural argument begins with the trespass provision. Section 221.2(1) makes it an offense to enter, or surreptitiously remain in, a building or occupied structure, or a separately secured or occupied portion of one, knowing that one is not licensed or privileged to do so, and it grades the offense as a misdemeanor in a dwelling at night and as a petty misdemeanor otherwise.31 Burglary describes the same kinds of places and the same kind of unlicensed entry, since § 221.1(1) excuses only entries made when the premises are open to the public or the actor is licensed or privileged.32 What burglary adds is the purpose to commit a crime therein, and that addition carries the grade up, because burglary is at least a felony of the third degree under § 221.1(2).33 On otherwise matching facts of entry, then, the purpose element is the only thing separating a petty misdemeanor from a felony.
That observation shows what would go wrong if the unlicensed entry could fill the purpose slot. A criminal trespasser under § 221.2(1) enters knowing the entry is unlicensed, so entering is exactly what the trespasser means to do, and entering without license is itself an offense. If that offense could count as the crime the actor intended to commit in the premises, every trespasser would hold the required purpose at the moment of entry, and every trespass would be a burglary. The purpose element would then sort no one, because anyone the entry element already caught would satisfy it automatically, and the gap the Code draws between a petty misdemeanor and a felony would disappear. The same reasoning covers an intruder whose plan is to stay, since remaining without license is part of the trespass offense too, so a plan to remain cannot be the separate crime either. The word "therein" prevents the collapse by demanding a further criminal design aimed at what will happen inside, and that design is the added culpability that justifies the heavier treatment. The usual error is treating the trespass itself as the crime intended.
The two intruders differ in one respect: whether anything criminal was planned apart from being there. The seriousness of the planned crime is not the variable, because the prior subsection established that any crime qualifies, so a planned petty theft would have placed Sue on Rex's side of the line. What "therein" adds is a requirement of separateness. The planned crime must be something other than the entry or the unlicensed presence, and the later section on the target offense takes up whether it must ever actually be carried out.
A Minnesota prosecution tests the same line and makes a useful puzzle. A defendant entered his ex-wife's dwelling without her consent, in violation of an order for protection, and apparently meant to enter in violation of that order. He also encountered another person inside, and he was charged with first-degree burglary.35 The questions that accompany the decision ask why he does not satisfy every element of that offense, and they go on to ask what would follow if the facts had more clearly shown that his purpose in entering was to see his ex-wife.36 A dissent in the case refers to the district court's finding that the felony underlying the burglary charge was violation of the order for protection and not the "no-entry part" of the order.37 That phrase indicates the order contained commands besides the ban on entering, which shows why it matters which command the prosecution says the defendant meant to violate. The dissent also suspects that the real concern was whether burglary should be charged when the more accurate description of the conduct is violation of the order itself.38 The material here does not set out how the majority resolved the problem, so the productive exercise is to run it through the Code's text.
The Code's structure frames the inquiry in two parts. If the only crime the defendant intended was the act of entering in violation of the order, then the entry is serving as both the act element and the intended crime, and nothing remains for "therein" to do. If the defendant meant to commit some other crime once inside, such as an assault on a person he expected to find there, or a separate violation of the order that could occur only after he arrived, the purpose element has something independent to work on. Burglary statutes differ across jurisdictions, so a real prosecution under a particular state's law turns on that state's own wording, and the analysis above applies the Model Penal Code's language.
