Prison sentences for arson run from about one year at the low end to life imprisonment or the death penalty when someone dies in the fire. How many years in prison you face for arson depends on three things: whether the case is charged in state or federal court, the degree of the offense, and whether people were placed in danger or harmed. Federal convictions carry mandatory minimums starting at five years. State sentences follow the degree of the charge, which tracks how dangerous the fire was.
State Prison Sentences by Degree
Most states divide arson into degrees, and the degree is the single biggest factor in the eventual sentence.
First-degree arson is the most serious. It applies when someone intentionally sets fire to an occupied building, such as a home or apartment where people are present. Even if no one is physically injured, the presence of people inside or nearby elevates the charge. Prison terms commonly range from 10 to 25 years, and some states authorize life imprisonment when the fire endangered multiple lives or caused catastrophic damage.
Second-degree arson covers intentionally burning an unoccupied structure, such as an empty warehouse, a shuttered office, or a barn. Sentences typically fall between 5 and 20 years, with the value of the destroyed property pushing the term higher within that range.
Third-degree arson applies to fires set to personal property, abandoned buildings, vehicles, or open land like a field or forest. Prison terms generally run from 1 to 10 years.
A handful of states recognize additional degrees below third. New York, for example, has five degrees of arson, and the lowest is a misdemeanor for recklessly starting a fire that damages someone else’s property. Where a misdemeanor arson charge exists, the maximum is typically up to one year in county jail.
Fines for felony arson convictions generally range from $10,000 to $50,000, and many states allow larger fines when the damage is extensive.
When Arson Becomes a Murder Charge
If someone dies in a fire that was intentionally set, the arsonist can face a murder charge under the felony-murder rule. This doctrine exists in most states and under federal law. It lets prosecutors charge anyone committing a violent felony with murder when a death results from that felony, even if the person never intended to kill anyone. Arson is one of the core felonies that triggers the rule. A felony-murder conviction can carry a life sentence or, in states that allow it, the death penalty.
Federal Arson Sentences
Federal arson sentences are often harsher than state penalties because they carry mandatory minimums a judge cannot reduce. Two statutes do most of the work.
18 U.S.C. § 844: Arson Affecting Interstate Commerce
Section 844(i) applies when someone uses fire or explosives to damage property used in interstate or foreign commerce, a category that covers businesses, commercial buildings, rental properties, and vehicles used in commerce. Penalties scale with harm:
- No injuries: a mandatory minimum of 5 years and a maximum of 20 years.1Office of the Law Revision Counsel. 18 USC 844 – Penalties
- Personal injury, including injuries to public safety officers responding to the fire: a mandatory minimum of 7 years and a maximum of 40 years.1Office of the Law Revision Counsel. 18 USC 844 – Penalties
- Death: imprisonment for any term of years, life in prison, or the death penalty.1Office of the Law Revision Counsel. 18 USC 844 – Penalties
The same penalties apply to an attempted arson under this statute, even if the fire never fully ignites. One boundary worth noting: the Supreme Court held in Jones v. United States that a private home used solely as a residence does not qualify as property used in interstate commerce, so federal prosecutors cannot charge arson of an owner-occupied home under § 844(i) unless the property has some active commercial use.2Justia U.S. Supreme Court Center. Jones v. United States, 529 U.S. 848 (2000)
18 U.S.C. § 81: Arson on Federal Land and Military Property
Section 81 covers arson within areas under special federal jurisdiction, including military bases, national parks, federal courthouses, and vessels at sea. The base penalty is up to 25 years in prison plus a fine equal to or greater than the cost of repairing or replacing the damaged property.3Office of the Law Revision Counsel. 18 U.S. Code 81 – Arson Within Special Maritime and Territorial Jurisdiction
If the fire involves a dwelling or places any person’s life in jeopardy, the penalty jumps to a fine, imprisonment for any term of years or for life, or both.3Office of the Law Revision Counsel. 18 U.S. Code 81 – Arson Within Special Maritime and Territorial Jurisdiction
Arson for Insurance Fraud Extends the Total
Setting a fire to collect an insurance payout usually results in additional federal charges for mail fraud or wire fraud, since insurance claims travel through the mail or electronic communications. Mail and wire fraud each carry a maximum of 20 years in federal prison, and those sentences can be imposed on top of the arson sentence. Federal prosecutors tend to stack these charges, so a single arson-for-profit scheme can produce multiple convictions running consecutively: 5 to 20 years for the arson, plus up to 20 years per fraud count.
What Moves a Sentence Up or Down
Within the sentencing range for any given arson charge, judges weigh aggravating and mitigating factors to arrive at a specific number of years.
Aggravating factors that push a sentence toward the maximum include:
- Injuries or death to victims, firefighters, or bystanders.
- Fires set at places of worship, schools, hospitals, or community centers.
- A prior criminal record, especially prior arson-related convictions.
- A financial motive, such as insurance money or destroying evidence of another crime.
- Use of gasoline, chemicals, or explosive devices, which shows planning.
Mitigating factors are less common in arson cases but exist. Young age, lack of prior criminal history, mental health issues, or a minor role in a larger scheme can help. Genuine cooperation with investigators, particularly when it helps solve related crimes, sometimes leads to reduced sentences. Judges tend to be less lenient in arson cases than in many other felony categories because of the risk to innocent people.
Money Owed on Top of Prison Time
Prison is not the end of the punishment. Federal law requires mandatory restitution for victims of crimes of violence and property offenses when an identifiable victim has suffered physical injury or financial loss, and arson qualifies under both categories.4Office of the Law Revision Counsel. 18 U.S. Code 3663A – Mandatory Restitution to Victims of Certain Crimes Restitution covers rebuilding costs, destroyed equipment and inventory, lost business income, and medical expenses. It goes directly to the victim, and the obligation survives bankruptcy. Most states have similar restitution requirements for state arson convictions.
A criminal conviction does not prevent victims from also suing in civil court. Civil plaintiffs can recover compensatory damages for property repair, lost income, medical bills, pain and suffering, and emotional distress. Many states also allow punitive damages when the conduct was willful and malicious. These civil judgments can reach into the hundreds of thousands or millions of dollars.
After a federal prison sentence, an arsonist serves a period of supervised release. For the most serious arson convictions classified as Class A or Class B felonies, supervised release can last up to five years; lower-level felony arson convictions carry up to three years.5Office of the Law Revision Counsel. 18 USC 3583 – Inclusion of a Term of Supervised Release After Imprisonment Violating the conditions can send a person back to prison.
How Long Prosecutors Have to Bring Charges
Arson investigations can take years, because a fire may initially look accidental and only later reveal itself as deliberate. Federal law gives prosecutors up to 10 years from the date of the offense to bring arson charges under 18 U.S.C. § 81 or § 844.6Office of the Law Revision Counsel. 18 USC Ch 213 – Limitations If the arson resulted in a death, there is no time limit, because capital offenses have no statute of limitations. State limitations periods vary but are generally longer than for other property crimes because of how difficult fire investigations can be.
