Arson Charges in New York: Degrees, Penalties, and Defenses

Arson charges in New York are divided into five degrees, running from a Class A misdemeanor for intentionally damaging someone else’s property by fire up to a Class A-I felony that carries a minimum of 15 years and a maximum of life in prison. Which degree you face turns on three questions: was the fire set intentionally or recklessly, was anyone inside the building or vehicle, and was an incendiary device or financial motive involved. Penalties climb sharply as those factors stack, and a conviction at any level leaves a permanent record with consequences that outlast the sentence itself.

The Five Degrees of Arson

First Degree

First-degree arson under Penal Law 150.20 is a Class A-I felony, the most serious arson charge in the state.¹ The prosecution must prove you intentionally damaged a building or motor vehicle by fire or explosion, that a non-participant was present, and that you either knew they were there or the circumstances made their presence reasonably possible.

That alone isn’t enough. First degree also requires at least one aggravating factor: the use of an incendiary device or explosive, serious physical injury to a non-participant, or setting the fire with the expectation of financial gain. Both elements have to line up. The presence of another person and one of the aggravating factors work together, which is what separates first degree from second.

Second Degree

Second-degree arson under Penal Law 150.15 is a Class B felony and is classified as a violent felony offense.²³ It applies when you intentionally start a fire that damages a building or motor vehicle while a non-participant is inside and you either know they are there or the circumstances make their presence reasonably possible. No incendiary device, explosion, injury, or financial motive is required. The line between second and third degree is another person’s presence and your awareness of it.

Third Degree

Third-degree arson under Penal Law 150.10 is a Class C felony.⁴ It covers the intentional destruction of a building or motor vehicle by fire or explosion, whether or not anyone was inside. The prosecution does not have to prove awareness of another person’s presence. It does have to prove the fire was deliberately set rather than accidental. Third degree is not a violent felony, which affects both the sentencing structure and release eligibility.

Fourth Degree

Fourth-degree arson under Penal Law 150.05 is a Class E felony and is the charge that captures reckless fire-setting.⁵ You face this charge when you intentionally start a fire or cause an explosion and recklessly damage a building or motor vehicle as a result. The mental state is what distinguishes it from third degree: third requires intent to damage the property, fourth requires only intent to start the fire combined with recklessness about the damage.

Fourth degree has a built-in affirmative defense. If no one other than you had any ownership or possessory interest in the property, you can raise that at trial. Setting fire to your own car in an empty lot where no one else has a stake could qualify, though the burden of proving it falls on the defense.

Fifth Degree

Fifth-degree arson under Penal Law 150.01 is the lowest arson charge and the only one classified as a misdemeanor rather than a felony.⁶ It applies when someone intentionally damages another person’s property by starting a fire or explosion without the owner’s consent. Unlike the felony charges, fifth degree does not require damage to a building or motor vehicle. Any property qualifies. The offense is a Class A misdemeanor carrying up to one year in jail.

Prison Terms by Degree

Sentences depend on the degree, whether the offense is classified as a violent felony, and the defendant’s criminal history. New York uses indeterminate sentences for some arson charges and determinate sentences for others, which changes how release works in practice.

First degree (Class A-I felony): an indeterminate sentence with a maximum of life imprisonment. The court sets the minimum at between 15 and 25 years. Life without parole does not apply to arson; that sentence is reserved for certain murder convictions.⁷
Second degree (Class B violent felony): a determinate sentence of 5 to 25 years. Under Jenna’s Law, a first-time violent felony offender must serve at least six-sevenths of the sentence before becoming eligible for conditional release.⁸⁹
Third degree (Class C felony): an indeterminate sentence with a maximum of up to 15 years. The minimum is set by the court at no less than one year and no more than one-third of the maximum imposed.⁷
Fourth degree (Class E felony): an indeterminate sentence with a maximum of up to four years. The court can also impose a definite sentence of one year or less if it finds a longer term would be unduly harsh.⁷
Fifth degree (Class A misdemeanor): up to one year in jail.

These ranges apply to first-time offenders. Prior felony convictions push the minimums up substantially. A second felony offender convicted of a Class B felony faces 9 to 25 years; a second felony offender convicted of a Class C felony faces 6 to 15 years.¹⁰

Post-Release Supervision and Restitution

Prison time isn’t the end of the sentence for violent felony convictions. After release from a second-degree arson sentence, you serve a mandatory period of post-release supervision. For a Class B or Class C violent felony, that period runs from two and a half to five years.¹¹ Violating supervision terms can send you back to prison. This is the piece people often overlook when weighing plea offers.

Courts can also order restitution to victims for their actual out-of-pocket losses. Restitution in felony cases is generally capped at $15,000 unless the defendant consents to a higher amount or the court exercises its discretion to order the return of property or reimbursement of medical expenses beyond that cap.¹² For fifth-degree arson, the cap is $10,000. Those caps apply only in the criminal case. A victim can bring a separate civil lawsuit with no statutory ceiling on what a jury can award for property damage, lost income, or injuries.

What the Prosecution Must Prove

Every arson charge requires proof beyond a reasonable doubt that the fire was not accidental. First through third degree require intentional damage to the property. Fourth degree requires intent to start the fire combined with recklessness about the resulting damage. Fifth degree requires intent to damage someone else’s property.

Prosecutors also have to tie the defendant to the fire, which usually leans heavily on circumstantial evidence. Fire investigators look for burn patterns consistent with intentional ignition, multiple points of origin, accelerants like gasoline, and signs that suppression systems were tampered with. Any of these findings can turn what looks like an accident into a criminal case. Expert testimony often becomes the centerpiece, and the reliability of that testimony is where many arson trials are won or lost.

Higher degrees add burdens. Second degree requires proof that a non-participant was present and that the defendant knew or should have reasonably anticipated it. First degree layers on an aggravating factor such as an incendiary device or a financial motive. Total destruction isn’t required. Damage beyond trivial scorching is enough.

Common Defenses

The strongest arson defense usually attacks the prosecution’s theory of how the fire started. If a defense expert can credibly show that the fire originated from an electrical fault, a heating malfunction, or another accidental cause, the intentional element collapses. Fire science has changed significantly in recent decades, and some forensic techniques investigators once relied on have been discredited. Defense attorneys routinely challenge outdated burn-pattern analysis and unscientific accelerant conclusions.

Mistaken identity is another common defense when the case rests on circumstantial evidence. Alibi witnesses, phone records placing the defendant elsewhere, or surveillance footage that contradicts the prosecution’s timeline can all break the link between defendant and fire. Proving arson occurred is one thing. Proving who set it is a separate and often harder question.

Procedural defenses focus on how the evidence was collected. Illegal searches, warrantless seizures, and interrogations conducted without proper Miranda warnings can all lead to suppression. In financial-motive cases, the defense may point to other people, such as a business partner, an employee, or a co-owner, who had an equal or stronger reason to set the fire.

Fourth-degree arson carries its own statutory defense. If no one else had an ownership or possessory interest in the damaged property, that fact is an affirmative defense at trial.⁵

When Federal Charges Apply

Arson in New York can also trigger federal charges under 18 U.S.C. § 844 when the fire involves federal property, property receiving federal financial assistance, or property used in interstate commerce. Federal penalties run on a different scale:

Property damage with no injury: 5 to 20 years in federal prison.
Property damage causing personal injury or substantial risk of injury: 7 to 40 years.
Property damage causing death: a minimum of 20 years, up to life imprisonment, or the death penalty.¹³

Federal and state charges can run in parallel. A fire that damages a post office, a federally subsidized housing complex, or a facility taking federal grants brings the case into federal jurisdiction. Fires damaging property used in interstate commerce, which courts have read broadly, can also qualify. A defendant convicted in both systems can face consecutive sentences.

Federal cases also carry mandatory restitution under the Mandatory Victims Restitution Act. The court must order the defendant to pay for property damage, medical costs, lost income, funeral expenses where someone died, and costs the victim incurred participating in the prosecution.¹⁴ Unlike the state’s $15,000 felony cap, federal restitution has no ceiling.
