How Minnesota defines third-degree arson

Section 609.563 begins with conduct and state of mind: the accused must unlawfully, by fire or explosives, intentionally destroy or damage real or personal property. It then requires one of three value circumstances. That design makes the offense more complicated than the familiar shorthand “burning property worth $300 to $1,000.”

The statute can apply to a vehicle, furniture, merchandise, equipment, landscaping, outdoor property, documents, machinery, contents of a room, or another item of value. It is not limited to someone else’s property. The 1985 Legislature removed the former “belonging to another” limitation, and the present text applies to “any real or personal property.”

Buildings usually require immediate comparison with first- and second-degree arson. Minn. Stat. § 609.562 (2026) covers an intentionally damaged building outside first degree regardless of value. A prosecutor cannot avoid the statutory distinctions by describing every object as generic property. Counsel should identify exactly what burned, whether it was a “building,” and which offense the legislature assigned to it.

Damage is sufficient; total destruction is unnecessary. Scorching, melting, smoke damage, loss of function, or repairable fire damage may satisfy the conduct element if the State proves the required intent and value circumstance. Conversely, a char mark does not automatically establish a felony. The property and the valuation must be proved.

A validly authorized fire can be excluded. Minn. Stat. § 609.564 (2026) states that a person does not violate first-, second-, or third-degree arson or the principal wildfire-arson provision by setting a fire under a valid license or permit or with written permission from the fire department where the fire occurs. Authorization has conditions; a permit for one location, date, material, or weather condition does not necessarily authorize something else.

The statute’s three value branches

Clause (a): intended property worth more than $300 but less than $1,000. This branch turns on what property the accused intended to damage or destroy, not only on the repair bill ultimately generated. The State must identify the intended property, prove its value was within the open interval, and prove the accused intended fire damage to it.

Suppose a person intentionally ignites a $600 chair, but firefighters extinguish it after $100 of actual damage. Clause (a) can still be charged if the evidence proves intent to damage or destroy the $600 chair. The statute speaks of the value of the property intended to be damaged, not an actual-loss minimum for this branch.

Clause (b): foreseeable unintended damage of $300 or more. A person may intentionally burn one item and unintentionally damage another. If the additional damage could reasonably have been foreseen and the unintentionally damaged property was worth at least $300, clause (b) may apply. The State must prove the separate damage, value, and objective foreseeability.

For example, intentionally setting papers on fire next to upholstered furniture may expose the furniture to foreseeable damage. But the answer depends on the materials, distance, container, room, suppression measures, fire behavior, and what a reasonable person could foresee in those circumstances. The fact that damage occurred does not prove it was reasonably foreseeable before it occurred.

Clause (c): aggregation. The statute permits the property specified in clauses (a) and (b) to be considered in the aggregate when its value reaches at least $300. This branch can matter when several items are involved or when intended and foreseeable unintended property must be evaluated together.

Aggregation is not permission to total every loss associated with the event. The property must fit the statutory description, and the State must establish each value included in the sum. Emergency response costs, cleanup labor, business interruption, sentimental value, and unrelated repairs do not automatically become the value of the property specified in clauses (a) and (b).

The statutory issue at exactly $1,000

The current wording creates an issue many summaries overlook. Second-degree arson covers nonbuilding real or personal property valued at more than $1,000. The intentional-property branch of third-degree arson covers property valued at more than $300 but less than $1,000. Neither phrase expressly includes intended nonbuilding property valued at exactly $1,000.

A court should not silently change “more than” to “at least” or “less than” to “no more than.” Criminal statutes must give notice and are applied according to the words the legislature enacted. When credible evidence fixes intended property at exactly $1,000, charging classification, included offenses, jury instructions, and proof of value require focused briefing.

The issue is not merely academic. Valuation evidence often produces a range rather than a perfect number. An appraiser may say $900 to $1,100; an owner may estimate $1,000; a used-item listing may show asking prices on both sides; and a repair estimate may not measure market value. The State retains the burden of proving the value bracket beyond a reasonable doubt.

Clause (b) uses different language. It requires foreseeable unintended damage to property “of the value of $300 or more” and does not state the same $1,000 ceiling. Clause (c) also uses an aggregate of $300 or more. Those branches must be analyzed according to the property and mental-state allegations actually charged. They should not be used as labels to bypass the distinct proof required for unintended damage or aggregation.

Fifth-degree arson covers intentionally burning real or personal property “of value” when the higher degrees are not proved. Thus, a disputed boundary can affect whether the State has a felony, a misdemeanor, or a different offense. Defense counsel should obtain the complaint, probable-cause statement, charging amendment history, proposed jury instructions, and all valuation evidence before accepting the prosecutor’s classification.

Elements the State must prove beyond a reasonable doubt

A third-degree arson case ordinarily requires proof that the accused intentionally caused fire or explosive damage, did so unlawfully, and satisfied at least one of the statute’s value alternatives. The complaint and jury instructions must tell the defense which theory is alleged.

The first dispute is often whether the fire was incendiary at all. A suspicious scene, an undetermined cause, or the absence of an immediately apparent accidental cause does not establish intentional burning. Investigators must distinguish origin from cause and cause from the identity of the person responsible.

The second dispute is identity. Motive, access, presence nearby, or a prior argument may be relevant, but no one fact proves who started a fire. The State may rely on surveillance, witnesses, location records, physical evidence, statements, or circumstantial inferences. Each item must be authenticated and considered with reasonable innocent explanations.

The third dispute is criminal intent. A person may intentionally light a candle, grill, campfire, burn barrel, torch, cigarette, firework, or paper without intending unlawful property damage. An escaped or mishandled fire can support negligence allegations without proving intentional arson. The intent must concern the prohibited property damage, not merely the act of creating a flame.

The fourth dispute is causation. The charged fire or explosion must have damaged the identified property. Smoke, water, overhaul, collapse, weather, demolition, and later handling can add damage. The State must distinguish loss caused by the alleged offense from loss caused by unrelated conditions when that distinction matters to the statutory theory or restitution.

The fifth dispute is value and foreseeability. Clause (a), clause (b), and clause (c) ask different questions. A general verdict cannot conceal a failure to prove the alternative submitted, and counsel should examine whether juror unanimity, election, or specific instructions are needed under the case’s allegations.

The prosecution generally has five years to file a third-degree arson charge under Minn. Stat. § 628.26(k) (2026). Statutory exclusions can affect the calculation, including certain periods when the accused was not an inhabitant or usual resident of Minnesota.

How property value is proved and challenged

Property value is not synonymous with the amount on an insurance schedule, the cost of a new replacement, the owner’s original purchase price, the repair invoice, or the amount of restitution requested. The usual criminal-law inquiry looks to retail market value at the time of the offense, considering the market in which the item would have been sold.

For a vehicle, relevant evidence can include year, make, model, mileage, title status, mechanical condition, prior collision damage, rust, tires, options, maintenance, recent repairs, operability, actual offers, comparable sales, and salvage value. For electronics, tools, furniture, equipment, or merchandise, age, condition, obsolescence, missing components, warranties, local demand, and documented used sales may matter.

An owner may give a value opinion, but cross-examination should test its foundation. When did the owner last inspect the item? Is the estimate based on replacement with a new product rather than the used item’s market? Did the owner disclose prior defects to the insurer, a buyer, or police? Are receipts for the same model, a different model, or improvements? Was the property already damaged?

Repair cost may be evidence, but it answers a different question from pre-fire market value. A $700 repair to a $250 item does not necessarily make the item worth $700. Conversely, an item can be worth $800 even if the flame caused only $100 in repairable damage, because clause (a) looks to the value of property intended to be damaged.

Insurance documents need context. Coverage limits are often calculated from replacement cost, blanket business-property limits, estimates made years earlier, or policy formulas. A proof of loss may state a position in a civil claim rather than establish market value beyond a reasonable doubt. Obtain the adjuster’s photographs, inventory, depreciation calculations, source data, prior statements, and all revisions.

Aggregation requires item-level discipline. List each item, the alleged statutory branch, the valuation method, the date, and the supporting witness or record. A total without admissible support for its components is not proof. If some items fall outside the charged intent or were not foreseeably exposed, they should not be included merely because they appeared on the same claim.

What “reasonably could have been foreseen” means

Clause (b) prevents a person who intentionally starts a property fire from ignoring reasonably predictable spread merely because a second item was not the target. The inquiry is objective and fact-specific: could the unintended damage reasonably have been foreseen in the circumstances?

Relevant facts include the size and type of ignition, fuel load, materials, spacing, ventilation, weather, wind, suppression equipment, container, floor and wall construction, whether a door was open, whether occupants were present, how long the fire could burn, and any effort to contain or extinguish it.

Hindsight is dangerous. Once a room is damaged, the spread can seem inevitable. The legal question concerns reasonable foreseeability when the accused acted. An expert should explain what fire development was predictable from the known conditions, not merely describe what eventually happened.

The accused’s own actions can cut both ways. Moving combustible materials closer, adding fuel, leaving the area, blocking detection, or disabling suppression may support foreseeability and intent. Using a metal container, clearing the surrounding area, keeping water nearby, or extinguishing an unexpected spread may support a narrower intended burn—though none of those facts automatically resolves the charge.

Clause (b) still begins with an intentional unlawful fire-damage offense. It is not a substitute for Minnesota’s gross-negligence statute. If the accused did not intentionally destroy or damage any property, the State must identify another valid offense rather than using foreseeable consequences to erase the required intentional act.

Expert testimony may help, but jurors can evaluate ordinary foreseeability where the facts are within common experience. Counsel should test whether the expert assumed disputed facts, overstated certainty, ignored containment measures, or relied on post-fire conditions that were not knowable beforehand.

Third-degree arson compared with related offenses

First-degree arson. Minn. Stat. § 609.561 (2026) covers dwellings, connected or appurtenant structures, specified non-dwelling building fires involving another person’s actual or reasonably possible presence, and non-dwelling buildings when defined flammable material starts or accelerates the fire. Its maximum is twenty years.

Second-degree arson. Section 609.562 covers non-first-degree buildings regardless of value and other real or personal property worth more than $1,000. Its maximum is ten years.

Third-degree arson. Section 609.563 is the felony analyzed here. It focuses on the specified intended, unintended, or aggregated property values and carries a five-year maximum.

Fourth-degree arson. Minn. Stat. § 609.5631 (2026) is a gross misdemeanor for intentionally burning personal property in a multiple-unit residential building or public building when the first three degrees were not committed. Its setting—not merely property value—is central.

Fifth-degree arson. Minn. Stat. § 609.5632 (2026) is a misdemeanor for intentionally burning real or personal property of value. It often becomes the comparison when the State cannot prove the felony value circumstance.

Student ignition devices. Minn. Stat. § 609.5633 (2026) creates a petty misdemeanor when a student uses matches or another ignition device inside an educational building under circumstances presenting an obvious fire risk, if first- through fourth-degree arson was not committed and the use was unauthorized.

Negligent fire. Minn. Stat. § 609.576 (2026) addresses gross negligence causing a fire to burn or get out of control and specified resulting injury or damage. The distinction between intentional damage and grossly negligent loss is often more important than the difference in dollar figures.

Evidence used in a third-degree arson case

Scene evidence. Investigators examine areas of origin, burn patterns, ventilation, fuel packages, electrical and mechanical systems, debris, containers, fire-alarm data, suppression, weather, and firefighter observations. Collapse and overhaul can change the scene, so original photographs, video, diagrams, and body-camera footage matter.

Laboratory evidence. Debris may be tested for ignitable-liquid residue. A positive result can identify a class of product, but it does not prove who introduced it or why it was present. Lawful fuels, solvents, cleaners, equipment, adhesives, and contamination must be considered. Chain of custody and sampling locations should be documented.

Witness accounts. Owners, neighbors, occupants, firefighters, employees, and first responders may address timing, access, prior condition, value, statements, and conduct. Early recorded statements are often more useful than a polished recollection months later. Inconsistencies can arise from stress, darkness, smoke, distance, suggestion, or ordinary memory limits.

Digital evidence. Surveillance, doorbell cameras, phone location, vehicle telematics, smart-home devices, access logs, web searches, messages, photographs, and social media can place a device or account in the narrative. The defense should obtain source data and test timing, accuracy, user attribution, edits, and missing context.

Financial and ownership evidence. Receipts, listings, appraisals, repair files, depreciation schedules, insurance inventories, tax records, purchase offers, and business records may bear on value and motive. The same record can support different inferences; an insured item is not automatically worth its coverage limit.

Statements. Police may compare accounts given to dispatch, firefighters, investigators, an insurer, family members, and online contacts. A person can lawfully decline a substantive police interview. If insurance duties require a statement, criminal and coverage counsel should coordinate its timing and scope.

Other-act evidence. Prosecutors sometimes seek evidence of prior fires, threats, or convictions. Similarity is not enough by itself, and the court must apply the governing evidentiary rules, notice requirements, proper purpose, proof standard, and unfair-prejudice balancing. A prior allegation cannot be used simply to say the accused has a propensity to commit arson.

Defenses to third-degree arson

Accidental or undetermined fire. The scene may support an electrical, appliance, cooking, battery, heating, smoking, mechanical, weather, or other accidental cause. Sometimes the most scientifically defensible conclusion is undetermined. The defense need not prove a single accidental cause; the State must prove intentional arson.

No intent to damage property. Intentionally creating a flame is not identical to intentionally damaging property. A lawful cooking fire, candle, grill, campfire, controlled burn, tool, or firework can escape or behave unexpectedly. The State must establish the charged state of mind.

Mistaken identity. Access, presence, or motive does not prove ignition. Alibi evidence, surveillance, reliable location data, witnesses, travel time, physical evidence, and alternative suspects can expose gaps.

Value outside the felony bracket. The intended property may be worth $300 or less, exactly $1,000, more than $1,000, or impossible to value reliably within the charged bracket. Each result can affect the degree. The defense should not assume that a higher value always helps; it may point toward a different charge, while an exact-boundary issue may defeat the charged formulation.

Unintended damage was not reasonably foreseeable. An unusual failure, hidden condition, unexpected wind shift, sudden intervention, or abnormal fire behavior may make spread genuinely unforeseeable. The inquiry must be made without hindsight.

Improper aggregation. The State may include property that was neither intended to be damaged nor foreseeably exposed, use unsupported owner estimates, combine market value with repair and cleanup costs, or double count components and finished property.

Authorized fire. A valid permit, license, or written fire-department permission can invoke section 609.564. Preserve the original authorization and evidence of compliance with its terms.

Unreliable or unlawfully obtained evidence. Search warrants, digital extractions, location records, custodial statements, expert opinions, laboratory results, hearsay, and prior-act evidence can present constitutional and evidentiary issues. A challenge depends on the actual record, not a generic rule.

Accomplice liability, attempt, and multiple participants

Under Minn. Stat. § 609.05 (2026), a person can be liable for another’s crime if the person intentionally aids, advises, hires, counsels, conspires with, or otherwise procures the other to commit it. Knowing the alleged principal, being nearby, or failing to stop a fire does not by itself establish intentional assistance.

Evidence may include obtaining an ignition source, selecting the property, providing access, serving as a lookout, moving items, encouraging the burning, arranging payment, supplying an alibi, or concealing evidence. The State must prove the accused’s knowledge and intent in relation to the crime, not merely suspicious association.

Jury instructions must explain the liability theory. A juror cannot be left to decide that a defendant is somehow “responsible” for another person without the findings section 609.05 requires. Published Minnesota authority has reversed an arson conviction where an instruction mentioned liability for another’s act but omitted the governing accomplice law.

An attempt charge is possible under Minn. Stat. § 609.17 (2026) when the accused intends to commit the offense and takes a substantial step beyond preparation. An extinguished ignition, interrupted effort, or nonfunctioning device can raise attempt questions. The State still must identify the intended property and value theory.

Conspiracy, insurance fraud, burglary, property damage, obstruction, or tampering charges may accompany an arson allegation. Each has distinct elements. Minnesota’s multiple-punishment statute contains an exception when specified arson was used to conceal another crime, so counsel must evaluate convictions and sentences as well as guilt.

Penalties and Minnesota Sentencing Guidelines

A completed third-degree arson conviction carries a statutory maximum of five years in prison, a $10,000 fine, or both. The court may also order restitution and impose probationary conditions. The maximum does not tell a defendant the presumptive sentence.

The current official Minnesota Sentencing Guidelines offense-severity table ranks third-degree arson at severity level 3. The presumptive disposition and duration depend on criminal-history score, custody status, attempt rules, and other Guidelines provisions. A sentencing worksheet should be checked rather than accepted by assumption.

The Minnesota Sentencing Guidelines Commission’s official Third-Degree Arson sentencing summary reports 29 people sentenced for completed third-degree arson from 2020 through 2024. Twenty cases had a presumptive stayed disposition and nine had a presumptive prison disposition. Four people received executed prison sentences, with an average pronounced term of 19 months. The Commission cautions that the report is monitoring data, not an authoritative interpretation or prediction.

Departure decisions can turn on amenability to probation or treatment, offense circumstances, remorse, restitution, prosecutor agreement, and legally sufficient mitigating or aggravating facts. A court must follow the law governing departures and cannot use an element of the offense as an aggravator without proper analysis.

Negotiated resolutions may involve fifth-degree arson, negligent fire, property damage, attempt, a stayed adjudication, or another disposition supported by the facts. A lower charge can materially alter custody exposure and record consequences. It can also change expungement eligibility.

Minn. Stat. § 609.035, subd. 3 (2026) provides that a conviction or acquittal for first-, second-, or third-degree arson or wildfire arson does not bar punishment for another crime in the same conduct when the arson was used to conceal that other crime. The provision can matter in a fire allegedly set after theft, burglary, fraud, or homicide.

Restitution, firearms, employment, and expungement

Restitution can include documented losses directly caused by the offense of conviction. The owner or insurer may seek property value, repair, cleanup, temporary replacement, lost use, or other amounts. The defense can challenge causation, valuation, depreciation, unsupported estimates, duplication, offsets, and whether a claimed loss belongs in criminal restitution.

Third-degree arson is not named in Minnesota’s “crime of violence” list in Minn. Stat. § 624.712, subd. 5 (2026); that arson portion lists first and second degree. That distinction does not mean a felony conviction has no firearm consequences. Federal law, probation conditions, other convictions, and a person’s status may independently prohibit possession. Advice must be individualized.

Background checks can affect employment involving buildings, vulnerable people, insurance, security, public safety, education, transportation, utilities, or positions of trust. Professional and occupational licensing bodies may require disclosure even when a sentence is stayed.

Immigration consequences require separate analysis. A state offense’s label does not settle federal immigration treatment. Noncitizens should obtain coordinated criminal and immigration advice before entering a plea.

Third-degree arson is not one of the felonies expressly listed for ordinary conviction expungement in Minn. Stat. § 609A.02, subd. 3(b) (2026). Other grounds may exist when proceedings resolve in the person’s favor, through diversion or a stay of adjudication, or when a felony is later deemed a gross misdemeanor or misdemeanor under applicable law. Eligibility depends on the final record and later history.

Insurance and civil proceedings can continue even if a criminal charge is dismissed. Statements, expert reports, and discovery can cross between matters. Defense counsel should coordinate before the accused gives a recorded statement, examination under oath, civil deposition, or sworn proof of loss.

What official Minnesota appellate opinions teach

State v. Gill, No. A19-1173, slip op. at 12–15 (Minn. Ct. App. July 13, 2020) (nonprecedential), addressed a burned vehicle charged as second-degree arson. The State offered an insurer’s valuation report, but its other evidence described severe mechanical defects and a vehicle in poor condition. The court concluded that “the state did not prove the value of the car beyond a reasonable doubt” and limited retrial to fifth-degree arson and insurance fraud.

Gill is nonprecedential, so it is not binding authority. Its reasoning remains practically important in any value-based arson case: an insurance number does not replace proof of the property’s actual condition and market value at the time of the fire.

State v. Williams, 759 N.W.2d 438, 443–46 (Minn. Ct. App. 2009), is a published first-degree arson opinion concerning accomplice instructions. The Court of Appeals reversed where jurors were told they could convict for a fire caused by the defendant or another person for whose acts he was liable but were not instructed on the legal requirements for that liability. The court stated: “Mere presence at the scene of a crime does not, by itself, prove liability for the crime of another.”

State v. Nelson, No. A22-1044, slip op. at 5–8, 12–18 (Minn. Ct. App. June 26, 2023) (nonprecedential), shows how a circumstantial arson case can be assembled. The evidence included statements about burning houses, location data placing the accused at the property near the likely ignition time, a denial of being there, limited possible appliance sources, and fuel containers. The court affirmed while also finding that identifying a prior conviction specifically as arson was erroneous but harmless on that record.

Nelson is nonprecedential and does not establish that presence or a fuel container proves arson. It illustrates the need to examine the circumstances as a whole, authenticate location technology, test alternative causes, and challenge propensity evidence.

The case lessons are concrete. Valuation must reflect the actual property. Accomplice liability requires more than proximity. Circumstantial evidence must be tested item by item and as a complete theory. Prior-fire allegations carry an acute risk that jurors will reason from character instead of proof.

What to do after a third-degree arson accusation

Do not alter evidence. Follow safety orders and do not enter a restricted scene, but avoid unnecessary demolition, disposal, repair, or cleaning until preservation issues are addressed. Document any work that cannot wait.

Save original files. Preserve photographs, video, messages, device backups, location history, surveillance, smart-device records, receipts, listings, appraisals, repair records, insurance documents, permits, dispatch records, and witness contact information. An original file with metadata is more useful than a screenshot.

Record the property’s pre-fire condition. Gather dated photographs, sales listings, repair estimates, inspection reports, maintenance files, ownership records, prior insurance descriptions, and witnesses. Value disputes are much harder after damaged property disappears.

Identify accidental causes. Note breaker problems, battery charging, heaters, appliances, smoking materials, cooking, candles, welding, recent repairs, fuel leaks, storms, power interruptions, and earlier odors or sounds. Do not test or dismantle the item yourself.

Do not guess during interviews. A person in shock may give inaccurate times or explanations that later look deceptive. Politely obtain legal advice before giving a recorded police, fire-investigator, or insurance statement.

Use the right experts. Cause and origin, electrical systems, mechanical failures, laboratory chemistry, digital evidence, and valuation are different disciplines. The necessary team depends on the contested issues.

Obey court conditions. Follow no-contact, exclusion, release, and evidence-preservation orders even if you own the property. Seek changes through counsel and the court.

Third-degree cases can look modest beside a major structural fire, but the charge is a felony and the scene is perishable. Early preservation can determine whether the defense has independent evidence or only the prosecution’s selected photographs and conclusions.
