Arson in the Fourth Degree in Minnesota
If you are being investigated for or charged with arson in the fourth degree, the starting point is the current text of Minn. Stat. § 609.5631. The statute is divided into multiple provisions, so the complaint must be matched to the exact subsection rather than treated as one undifferentiated accusation. This guide explains the statutory structure, every penalty approach identified in the selected section, the proof issues, the evidence questions, and the practical decisions that deserve attention before anyone predicts an outcome.
You will work directly with me.
If you hire me on a fourth-degree arson allegation, I investigate the charged personal item and exact interior space, obtain building-use and fire-scene records, test why higher degrees are excluded, and analyze the offense-date gross-misdemeanor ceiling and restitution.
Fourth degree covers personal property inside specified shared or public buildings
The offense is not a general “small arson” provision. The burned object must be personal property, the location must be a multiple-unit residential building or a listed public building, and the conduct must not constitute first-, second-, or third-degree arson.
- Object
- Personal property—not the building theory itself. The burned item and any separate structural damage must be identified from the scene evidence.
- Location
- A building with two or more apartments, or a statutorily defined public building. Use and access on the alleged date require proof.
- Higher-degree boundary
- First-, second-, and third-degree arson must not have been committed.
- Classification
- Gross misdemeanor: up to 364 days and a $3,000 fine.
Why the statutory maximum is not a sentence prediction
Fourth-degree arson is a gross misdemeanor, so the felony Guidelines grid does not determine the sentence. The court considers the statute, record, negotiated position, restitution, probation law, and lawful sentencing factors.
Official sources and cited authority
Offense-date rule: Use §609.5631 and the gross-misdemeanor ceiling in effect on the alleged date. The ceiling changed to 364 days in 2023, so older conduct requires the historical version; building use and the location of the personal property must also be fixed to the charged time.
Identify the exact object and room
A wastebasket, clothing, bedding, furniture, merchandise, paper, or another item may be personal property; damage to the structure can change the analysis. Photograph, collection, and laboratory records should identify the same item.
Prove the statutory building type
The State must establish two or more apartments or one of the listed public-building categories—not merely that other people sometimes enter. Lease files, floor plans, occupancy certificates, access policies, and licensing records can be more reliable than a witness label.
Locate the act within the building
A private unit, common hallway, business area, detached structure, patio, or outdoor location may present different statutory facts. Confirm the alleged item’s location on the offense date.
Build separate origin, cause, identity, and intent timelines
Chart the personal item’s location and ownership, the room or unit’s actual use, public access, occupancy, ignition, alarms and suppression, damage, scene security, witness access, investigator work, and reasons the first three degrees allegedly do not apply. Mixed-use buildings require space-specific evidence.
Demand the complete technical record
Focus the fire investigation on the charged personal property and interior location. Obtain room and unit photographs, floor plans, access and occupancy records, alarm and sprinkler data, electrical or appliance testing, debris sampling, laboratory results, video, witness observations, and alternative ignition sources.
Map every degree-setting fact to evidence
Prove the object was personal property inside either a building with two or more apartments or a listed or comparable public-assembly building. Then test the negative boundary: if first-, second-, or third-degree arson was committed, §609.5631 is not the governing fourth-degree theory.
The statute requires the right object, the right location, and the absence of a higher degree
Section 609.5631 prohibits intentionally, by fire or explosives, setting fire to, burning, or causing to burn personal property in a multiple-unit residential building or public building when the conduct does not constitute first-, second-, or third-degree arson. Each part matters. The State should identify the personal-property item, where it was located, the statutory building category, the intentional act, and why structural or value evidence does not establish a higher degree.
A “multiple unit residential building” means a building containing two or more apartments. The public-building definition is enumerated and broad: hotel, hospital, motel, dormitory, sanitarium, nursing home, theater, stadium, gymnasium, amusement-park building, school, museum, restaurant, bar, correctional institution, place of worship, or another building generally open to members of the public or used for public assembly. Whether a mixed-use, temporarily closed, private-club, or partly occupied property fits requires evidence of use, access, layout, and the charged area.
The personal-property limitation prevents the offense from being described as any fire inside one of those buildings. Identify what allegedly burned and whether the accusation is setting fire to that item or intentionally damaging the building. A flame that touches an item without burning it, smoke from an accidental event, and intentional burning that damages structural components present different factual and legal questions.
The prosecution must connect the person to intentional burning
Evidence may include eyewitness accounts, cameras, alarm records, access logs, recovered ignition devices, residue, messages, admissions, or conduct before and after the event. The defense should compare every time source and preserve native video. Short clips can omit who entered earlier, what an item contained, whether a flame was extinguished, or whether another person handled it. Witnesses may agree that smoke appeared while disagreeing about ignition and identity.
Fire-scene evidence should still be tested even when damage is limited. Determine whether the object was collected, photographed, tested, discarded, or moved; whether an accidental source was examined; whether the fire department documented origin and cause; and whether laboratory results confirm any claimed material. A lighter or matches may establish capability without proving use or intent. Section 609.5633 separately addresses a student’s ignition-device use inside an educational building under an obvious risk of fire when first through fourth degree arson was not committed and the use was not authorized by the school.
The higher-degree boundary is substantive
Fourth degree applies only if first, second, or third degree was not committed. Damage to a dwelling building, another building under first-degree presence or flammable-material facts, a non-first-degree building, other property worth more than $1,000, or property meeting § 609.563’s theories may support a different charge. Conversely, the State should not inflate a limited personal-property event by using restoration or business-loss figures that do not prove the elements of a higher section.
Fifth-degree arson under § 609.5632 is the misdemeanor comparison for intentionally setting fire to, burning, or causing to burn real or personal property of value. Fourth degree adds the protected shared/public-building location and gross-misdemeanor classification. The complaint, instructions, plea petition, and factual basis should name the location and object that distinguish the degrees.
Statements, searches, and consequences
Review any room, bag, vehicle, or device search for consent, warrant scope, nexus, particularity, and chain of custody. Review interviews from recordings for custody, warnings, invocation, coercion, interpretation, assumed facts, and whether the accused distinguished an intentional flame from an intent to burn the charged property. A shorthand report may erase that distinction.
The maximum is 364 days and $3,000, but custody, stayed time, probation, restitution, programming, no-contact conditions, trespass orders, employment and licensing effects, housing, school discipline, and immigration consequences may matter more in practice. Restitution should be supported by loss caused by the offense and the applicable procedure; it is not automatically every repair or closure expense claimed.
A complete review ends with an element chart, building-use proof, item-specific evidence, fire timeline, search-and-statement analysis, higher-degree comparison, restitution packet, and consequence sheet. That is more reliable than treating the charge as a reduced version of felony arson.

Frequently asked questions about Arson in the Fourth Degree in Minnesota
What building types qualify?
A building with two or more apartments or one of the public-building categories listed in § 609.5631, including buildings generally open to the public or used for public assembly.
What property must burn?
The statute specifies personal property inside the qualifying building. The alleged object and any structural damage should be identified precisely.
Why do first through third degree matter?
Fourth degree applies only when those higher degrees were not committed. Property type, building use, presence, material used, damage, foreseeability, and value can change the degree.
Is possessing a lighter enough?
No. The State must prove the intentional statutory act. A separate petty-misdemeanor ignition-device law may apply to specified student conduct in an educational building.
Is fourth-degree arson a felony?
No. It is a gross misdemeanor.
What is the maximum?
Up to 364 days, a $3,000 fine, or both.
A lawyer’s file review of Arson in the Fourth Degree in Minnesota
A useful defense analysis starts by slowing the case down. The title of the charge is not an element, and the largest number in a penalty provision is not a prediction. I read the count, the incorporated definitions, and the alleged facts side by side before I tell a client what I think.
Read the count as a set of propositions the State must prove
For Arson in the Fourth Degree in Minnesota, the governing text begins with Minn. Stat. § 609.5631 and the incorporated definitions in that section; Minn. Stat. §§ 609.561–609.563 for the higher-degree boundary. That citation matters because a familiar charge name can contain several statutory routes, definitions, and sentencing rules. I read the exact count, the alleged date, and every incorporated definition before deciding which facts are material and which allegations are simply part of the narrative.
Next, I connect each material fact to evidence the prosecution can actually present. The source might be a witness, a recording, a certified record, laboratory work, device data, or an admissible inference—but it should be identifiable and testable. That approach shows whether the real dispute concerns what happened, how evidence was obtained, whether it is admissible, or whether it proves the required element at all.
The evidence I would ask for first
For Arson in the Fourth Degree in Minnesota, I would not begin with a canned list of defenses. I would begin with the source file: ownership and authorization records, contracts, receipts, valuation material, surveillance video, access logs, account and device records, messages, witness interviews, inventory and loss calculations, restitution support, and the evidence offered to prove identity, intent, entry, possession, value, force, or lack of consent. A police summary can identify what an officer or witness says happened, but it cannot substitute for the recording, photograph, data, or document being summarized. The same is true of a complaint. It identifies the prosecution’s theory at the start of the case; it does not prove the theory.
I put those materials on one chronology. That lets me see what was known at each decision point, which account was contemporaneous, what appeared only after people spoke with one another, and where the record is silent. It also keeps an admissibility question separate from a factual one. A fact can be disputed even if the evidence was lawfully obtained. Evidence can also be accurate yet inadmissible for a particular purpose. Those are different arguments and should not be blurred together.
Read the charging document against the offense date
The alleged date matters because statutes, penalty thresholds, definitions, sentencing rules, and published decisions change. I save the version in force on that date and read the session-law history when the current online text is different. I also check whether a later amendment was merely clarifying or made a substantive change; that is a legal question, not an assumption. The same discipline applies to prior convictions and administrative events. A prior must fit the definition the charged statute actually uses, fall within any stated lookback period, and be proved by a reliable record.
I then compare the formal count with the probable-cause narrative and the discovery. If the prosecution’s theory shifts, I want the amended pleading and enough detail to prepare. If several factual alternatives are alleged, I identify whether they are separate elements, alternative means, enhancement facts, or merely evidentiary details. That distinction affects notice, motions, jury instructions, unanimity arguments, and how a verdict form should be read.
Separate an evidentiary weakness from a suppression issue
Not every troubling fact produces a motion to suppress. Suppression ordinarily requires a constitutional, statutory, or rule-based violation with a remedy that reaches the evidence at issue. A weak identification, an incomplete investigation, or a witness inconsistency may be powerful at trial without making evidence inadmissible. By contrast, a stop, search, interrogation, identification procedure, warrant, or test can raise a legal issue even when the resulting evidence appears incriminating. I analyze both tracks and do not promise dismissal simply because one problem exists.
For a search issue, I reconstruct what officers knew before each intrusion and what authority they claimed. For a statement, I examine custody, questioning, warnings, voluntariness, recording, and the complete context. For scientific or technical evidence, I request the method, underlying data, quality-control material, uncertainty information, and chain of custody. For hearsay or confrontation questions, I identify the actual statement, its purpose, the declarant, and the proposed foundation. Specificity matters; “the evidence is bad” is not a motion.
Prepare negotiation and trial at the same time
A plea decision should be compared with the case the State could present at trial, not with the complaint’s maximum penalty in isolation. I want to know the strongest admissible proof, the weakest required element, the realistic motion practice, the likely instructions, and the consequences of every proposed disposition. That includes custody, probation, treatment, restitution, driving, firearm restrictions, registration, employment or licensing, immigration consultation, family-court effects, and record consequences when they are actually triggered. I avoid telling a client that every collateral consequence applies to every conviction.
Trial preparation gives negotiation its credibility. Witness interviews, exhibit review, motions in limine, expert consultation, demonstrative evidence, jury instructions, and a clean theory of the case force both sides to confront what can be proved. Negotiation can continue while that work is underway. The two tracks are not opposites.
A case-law point worth keeping in its proper place
Appellate decisions matter, but a quotation should not be detached from the issue the court was deciding. In State v. Fleck, 777 N.W.2d 233, 236 (Minn. 2010), the Minnesota Supreme Court described sufficiency review as viewing the evidence “in the light most favorable to the conviction.” That is an appellate-review rule, not a reduction of the State’s trial burden. At trial, the prosecution still must prove every element beyond a reasonable doubt. I cite the case for the proposition it actually decided and then return to the charged statute, the jury instructions, and the admissible evidence in the present file.
What I would want you to understand before choosing an outcome
You should be able to identify the exact charge, the facts that set its level, the disputed elements, the evidence that matters most, the motions that have a legal basis, the realistic trial issues, and the concrete effect of each proposed resolution. If an answer depends on a missing report, recording, expert opinion, or certified record, I will say so. An honest answer about what remains unknown is more useful than a confident guess.
