Arson Sentence Length: Federal Ranges, State Degrees, and Enhancers

An arson sentence length runs from a couple of years for burning an unoccupied structure to life imprisonment or the death penalty when someone dies in the fire. Federal convictions for maliciously burning property tied to interstate commerce carry a mandatory minimum of 5 years and a maximum of 20, and state penalties are tiered by degree, with the harshest terms reserved for fires set in occupied buildings. What moves a sentence within those ranges is a familiar short list: whether anyone was hurt, whether the fire endangered people even if it didn’t reach them, how much was destroyed, the defendant’s prior record, and whether the fire was used to carry out another crime.

Federal Prison Ranges Under 18 U.S.C. § 844

Federal arson law sets three tiers of punishment based on harm. Burning federal property or property used in or affecting interstate commerce carries a base range of 5 to 20 years in prison. If the fire causes personal injury or creates a substantial risk of injury, including to firefighters and other first responders, the range moves to 7 to 40 years. If someone dies, the minimum is 20 years, the maximum is life, and the death penalty becomes available.¹

The 5-year floor applies even when no one is hurt. The interstate-commerce hook sweeps in most commercial buildings, rental properties, and businesses, so many arsons that look purely local end up in federal court.¹

State Degrees and Typical Sentences

Most arson prosecutions happen in state court, and most states sort the offense into degrees. The dividing line that drives sentence length is occupancy: burning a building where people are present, or likely to be, is treated far more seriously than burning an empty one.

First-degree arson covers occupied dwellings, hospitals, schools, and similar buildings. Prison terms commonly run from roughly 5 to 20 years, and some states authorize life in severe cases.
Second-degree arson covers unoccupied structures and non-dwellings. Ranges commonly fall between 2 and 10 years.
A third tier in some states covers personal property, vehicles, or open land, with shorter terms and occasional misdemeanor treatment for low-value property.

These are benchmarks, not universal rules. States vary in both the numeric ranges and what counts as “occupied.” Some treat a building as occupied if people could reasonably have been expected inside, even if no one actually was at the moment of the fire.

What Pushes an Arson Sentence Higher

Injury and Death

Injury is the single strongest driver. Federal law lifts the minimum from 5 to 7 years and the maximum to 40 when the fire causes personal injury or a substantial risk of it. Death lifts the floor to 20 years and puts life and capital punishment on the table.¹ State systems escalate the same way. A fire that injures apartment residents can also generate separate assault charges stacked on top of the arson count. Injuries to firefighters and other emergency responders count just as heavily as injuries to civilians.

Endangering People, Even Without Injury

Setting a fire near schools, hospitals, transit hubs, or in a dense neighborhood is treated as more serious even when no one is hurt. Under the federal sentencing guidelines, knowingly creating a substantial risk of death or serious injury triggers the highest base offense level for arson.²

The Amount of Damage

When the guidelines calculate the offense level from the property damage table, higher dollar losses directly raise the recommended prison range. Destroying a commercial building or landmark also produces very large restitution orders that outlast the prison term.

Using Fire to Commit Another Federal Felony

This is where sentences compound fastest. Under 18 U.S.C. § 844(h), using fire or an explosive to commit any felony prosecutable in federal court adds an automatic 10 years on top of the sentence for the underlying crime. A second offense under the same provision adds 20 years. The added term cannot be suspended, replaced with probation, or run at the same time as any other prison sentence. It stacks.¹

Arson-for-insurance cases feel this most sharply. The defendant faces the arson count, the insurance fraud count, and the consecutive 10-year add-on for using fire to commit the fraud.¹

Prior Record and Three Strikes

Under the federal sentencing guidelines, a longer criminal history raises the recommended range for every new conviction. The harder hit comes from 18 U.S.C. § 3559(c): a person convicted of a “serious violent felony” who has two or more prior serious violent felony convictions faces mandatory life imprisonment. Arson is listed as a serious violent felony for this purpose.³

A narrow exception exists. Arson will not count as a strike if the defendant proves by clear and convincing evidence that the fire posed no threat to human life and that the defendant reasonably believed it posed no such threat. An isolated empty structure might qualify; anything set in a populated area almost certainly will not.³

Many states have their own habitual-offender laws that produce similar escalations. Judges may also order sentences on multiple arson counts to run consecutively rather than at the same time.

What Can Bring a Sentence Down

Judges retain discretion to sentence below the guideline range when mitigating circumstances are present. The factors that carry weight in arson cases include a clean criminal record, a minor role in a scheme involving multiple defendants, documented mental health conditions or extreme emotional disturbance at the time of the offense, substantial cooperation with investigators, and genuine acceptance of responsibility. A guilty plea combined with acceptance of responsibility earns a 2- or 3-level reduction under the federal guidelines, which can remove months or years from the recommended range.

These factors lose most of their force against a mandatory minimum. A judge who thinks 5 years is too much for a particular defendant generally cannot go lower unless the prosecutor files a motion based on the defendant’s substantial assistance.

Restitution on Top of Prison

Federal law requires courts to order restitution whenever a crime of violence or property offense produces identifiable victims with physical injury or financial loss. Arson qualifies on both counts, and the order is mandatory, not discretionary.

Restitution in an arson case can cover property losses (the greater of the value at destruction or at sentencing, minus anything recovered), medical and psychiatric care for anyone injured, lost wages, funeral expenses if someone died, and victims’ costs for participating in the investigation and court proceedings. A single commercial fire can generate an order in the millions, and unlike some fines, restitution can survive bankruptcy in many circumstances and follow the offender indefinitely.⁴

Parole, Suspended Sentences, and One Firm Exception

Parole boards look at behavior during incarceration, participation in treatment or rehabilitation programs, expressed remorse, and assessed risk of reoffending. Completion of fire-specific treatment or mental health counseling can help.

Suspended sentences, where the offender serves some or all of the term outside prison under strict conditions, are generally reserved for lower-risk cases and typically require community service, restitution payments, and ongoing treatment. One firm limit applies at the federal level: the 10-year consecutive term under § 844(h) for using fire to commit another felony cannot be suspended, cannot be served on probation, and must be served in full.¹
