First-degree burglary is the most serious burglary charge in nearly every state. It applies when someone unlawfully enters or stays inside a home with the intent to commit a crime, and at least one dangerous element is present: a weapon, an explosive, or physical injury to someone inside. Because it combines a property offense with a direct threat to a person’s safety, first-degree burglary is treated as a violent felony almost everywhere, and convictions commonly bring 20 to 25 years in prison, often with a mandatory minimum.
What Makes a Burglary First-Degree
Every burglary case rests on two core elements the prosecution has to prove: unlawful entry (or unlawfully staying inside) and the intent to commit a crime once inside. First-degree burglary adds two more requirements on top of those: the building has to be a dwelling, and an aggravating circumstance has to be present.
Second-degree burglary generally covers unlawful entry into commercial buildings or other non-residential structures with intent to commit a crime. Third-degree burglary, where it exists as a separate charge, covers the least dangerous circumstances, sometimes as little as entering any building unlawfully with criminal intent. First-degree burglary sits at the top because it stacks the two factors courts care about most: the target is someone’s home, and the intruder either brought a weapon, hurt someone, or both.
The practical gap between degrees is huge. Burglarizing an empty warehouse and breaking into an occupied home while armed produce fundamentally different sentencing ranges, and the degree system exists to keep those situations separate.
The Entry Element
Entry does not require force. Walking through an unlocked door, climbing through an open window, or staying inside a building after your permission to be there has expired all satisfy the entry element. The FBI defines burglary as “the unlawful entry of a structure to commit a felony or theft” and notes that “the use of force to gain entry need not have occurred.”1Federal Bureau of Investigation. Burglary
The Intent Element
The mental element is where these cases are won or lost. Prosecutors must show the defendant intended to commit a crime inside the building at the moment they entered or decided to stay unlawfully. Someone who wandered into a structure without a plan and only decided to steal something after looking around may have a defense to burglary, even if theft and trespassing charges still stick. Proof of intent almost always comes from circumstantial evidence: what the person was carrying, what they did once inside, and what they took or tried to take.
The Aggravating Factors That Push a Case to First Degree
The exact statutory language varies by state, but the aggravating factors fall into a few well-established categories.
Weapons and Dangerous Instruments
The most common trigger is the presence of a deadly weapon, explosive, or dangerous instrument during the burglary. In most states, the weapon does not have to be used or even displayed. Being armed with a firearm, knife, or explosive while inside the dwelling or while fleeing is enough. Some states also elevate the charge when the intruder displays what appears to be a firearm, even if the object turns out to be a replica or is unloaded. In those states, the defendant can raise an affirmative defense that the weapon was inoperable, but the burden is on the defense, and a successful showing usually only reduces the charge to a lower degree rather than eliminating it.
Physical Injury to an Occupant
If anyone who is not participating in the crime is physically injured during the burglary, the charge almost always rises to the first degree. The injury does not need to be part of the original plan. A homeowner shoved, struck, or hurt while the intruder flees can turn what would have been second-degree burglary into a first-degree case. This is exactly the danger the top charge exists to address.
Accomplice Liability
One detail catches many defendants off guard: you can face first-degree burglary even if you personally carried no weapon and hurt no one. State statutes typically apply the aggravating factors to the defendant “or another participant in the crime.” If your accomplice brought a gun or injured someone inside, you face the same first-degree charge. This is where burglary law hits hardest, and it is the scenario that most often blindsides people who believed they were playing a minor role.
Why the Location Has to Be a Dwelling
In most states, first-degree burglary specifically targets dwellings, meaning places where people regularly sleep. That includes houses, apartments, mobile homes, hotel rooms, and houseboats currently used as residences. The definition turns on the structure’s use as a sleeping place rather than whether anyone happened to be home at the moment of the break-in, though some states do require the dwelling to be occupied or inhabited at the time.
Commercial buildings, offices, warehouses, and abandoned structures generally fall under second or lower-degree burglary because they lack that residential character. The reasoning is straightforward: a person asleep in their home is uniquely vulnerable, and the risk of a violent confrontation is highest in that setting.
Penalties
First-degree burglary is a high-level felony in every state. Maximum sentences commonly fall between 20 and 25 years in prison, and some states authorize longer terms. When aggravating factors stack up, such as serious bodily injury combined with a weapon, a life sentence is possible in certain jurisdictions. Many states impose mandatory minimums, meaning a judge cannot suspend the prison term or impose probation regardless of the circumstances. Defendants convicted of this charge should expect to serve a substantial portion of the sentence before becoming eligible for parole.
Fines can reach tens of thousands of dollars, and courts frequently order restitution to cover property damage, medical expenses, and other losses. Between court costs, fines, and restitution, the financial hit can persist for years after release.
In many states, first-degree burglary counts as a “strike” under habitual-offender or three-strikes sentencing laws. A single strike can dramatically increase the sentence for any future felony conviction, and a second or third strike can trigger mandatory sentences of 25 years to life. The long-term sentencing consequences extend well beyond the immediate case.
Defenses
Because burglary is a specific-intent crime, the strongest defenses attack either the intent element or the circumstances that pushed the charge into the first degree.
Lack of Intent
If the defense can show the defendant had no plan to commit a crime at the moment of entry, the burglary charge weakens. Someone who entered believing they had permission, or who entered for a lawful reason and only later committed an offense, may not meet the intent threshold. The fight usually plays out over circumstantial evidence like what the defendant was carrying, what they said to police, and how they behaved inside.
Intoxication
Because burglary requires specific intent, evidence of severe intoxication from drugs or alcohol can be relevant. If a defendant was so impaired they could not form the intent to commit a crime inside the dwelling, a jury may acquit on the burglary charge. This is a hard defense to win in practice. Courts typically require compelling evidence, often from witnesses, that the defendant was genuinely incapable of forming intent rather than merely drunk or high.
Challenging the Aggravating Factors
Even when the basic burglary elements are solid, the defense can fight the first-degree elevation. If the prosecution alleges a weapon was involved, the defense might argue the object was not a deadly weapon or dangerous instrument under the statute. Some states allow an affirmative defense that a displayed firearm was unloaded or inoperable, which can drop the charge to a lower degree. If the aggravating factor is injury, the defense may contest whether the injury actually occurred during the burglary or arose from a separate incident.
Suppression of Evidence
When police obtain evidence through an illegal search or seizure, the defense can move to suppress it under the Fourth Amendment. If a judge grants the motion, the evidence becomes inadmissible at trial. In burglary cases, that can gut the prosecution’s case if the suppressed evidence includes items found on the defendant, surveillance footage obtained without a warrant, or statements made during an unlawful detention. Suppression does not automatically dismiss the case, but it can remove the prosecution’s ability to prove key elements.
Consequences That Continue After the Sentence
Prison time and fines are only the start. A first-degree burglary conviction creates lasting obstacles.
Firearm Restrictions
Federal law prohibits anyone convicted of a crime punishable by more than one year of imprisonment from possessing firearms or ammunition. Because first-degree burglary is a serious felony in every state, this ban applies automatically and is permanent under federal law unless rights are formally restored.2Office of the Law Revision Counsel. 18 US Code 922 – Unlawful Acts
Voting Rights
The effect on voting rights depends on the state. Some states restore voting rights automatically upon release from prison, others require completion of parole or probation, and a few require a separate application or governor’s action. In rare cases, certain felony convictions can result in permanent disenfranchisement.3Vote.gov. Voting After a Felony Conviction
Employment and Professional Licensing
A violent felony conviction narrows career options significantly. Many professional licensing boards weigh felony convictions when evaluating applications, and a first-degree burglary conviction is particularly problematic because of its classification as a violent crime. Healthcare, education, law enforcement, finance, and law commonly screen for violent felonies. Some states have enacted reforms requiring licensing boards to consider whether a conviction is directly related to the profession rather than imposing a blanket ban, but in practice a first-degree burglary conviction remains a serious barrier.
Housing
Federal housing policy does not impose a blanket ban on applicants with felony convictions for public housing or Housing Choice Voucher (Section 8) programs. The only mandatory federal exclusions are for people convicted of manufacturing methamphetamine on federally assisted housing premises and those subject to lifetime sex-offender registration requirements. Beyond those narrow categories, local public housing authorities set their own admissions policies.4HUD Exchange. Are Applicants With Felonies Banned From Public Housing or Any Other Housing Funded by HUD In practice, a violent felony like first-degree burglary makes securing housing through these programs significantly harder, and many private landlords run background checks that will flag the conviction as well.
Immigration
For noncitizens, a first-degree burglary conviction can trigger deportation. Federal immigration law treats certain felonies as “aggravated felonies” that make a person deportable regardless of their status or how long they have lived in the United States. Whether a specific burglary conviction qualifies depends on the state statute involved and how federal courts in that circuit interpret it. Anyone who is not a U.S. citizen and facing a first-degree burglary charge should treat the immigration consequences as potentially just as severe as the criminal sentence.
