Arson Charges in Minnesota (First Through Fifth Degree)

The degrees of arson

• First-degree arson (§ 609.561). The most serious — intentionally setting fire to or burning a dwelling or other building where people are present or likely to be, or causing a fire that results in great harm. A felony with the highest penalties.
• Second-degree arson (§ 609.562). Intentionally burning other buildings or structures not covered by first degree. A felony.
• Third-degree arson (§ 609.563). Intentionally burning personal property over a certain value, or other property as defined. A felony.
• Fourth-degree arson (§ 609.5631). Setting fire in multiple-unit residential buildings or public buildings under defined circumstances. Typically a gross misdemeanor.
• Fifth-degree arson (§ 609.5632). Intentionally setting fire to or burning property of value, at the lower end. A misdemeanor.

There are also related offenses, including wildfire arson (§ 609.5641) and negligent fires (§ 609.576), which cover fires caused by negligence rather than intent. Certain controlled or authorized fires are specifically excluded (§ 609.564).

What the state has to prove

For most arson charges, the state must prove the fire or burning was intentional (or unlawful as defined for the degree) and that you were the person who set it. The two hardest things for the prosecution are usually:

• That it was arson at all — that the fire was intentionally set, rather than accidental or from an electrical, mechanical, or natural cause; and
• That you set it — identity, which in fire cases is often circumstantial.

Arson investigations rely heavily on fire-origin-and-cause analysis by investigators, and that science is frequently contestable.

Defenses to arson

• Accidental or non-intentional cause. The single most common arson defense — that the fire was accidental, electrical, mechanical, or otherwise not intentionally set. Modern fire science has discredited many older “arson indicators,” and origin-and-cause findings can be challenged with defense experts.
• Identity. Whether the state can prove you were the person who started the fire, as opposed to someone else or an unknown cause.
• Lack of intent. For the intentional degrees, whether the burning was intentional within the statute’s meaning.
• Valuation and degree. Challenging the property value or the type of structure, which can lower the degree and the exposure.
• Excluded fires. Whether the fire falls within a statutory exclusion (certain authorized or controlled burns).

Why arson cases need careful, early handling

Arson is unusual because the case often rises or falls on expert fire-science evidence rather than eyewitnesses, and because insurance and motive evidence frequently get woven in. The cause-and-origin determination drives everything, so getting an independent review of the fire investigation early — before evidence is lost — can be decisive. As with any serious charge, what you say to fire and police investigators matters, and it is wise to consult an attorney before doing so.
