The arson statute of limitations depends entirely on where the fire happened and who is prosecuting. Federal prosecutors generally have 10 years to bring arson charges.1Office of the Law Revision Counsel. 18 USC 3295 – Arson Offenses State deadlines run anywhere from four years to no limit at all, and a fire that killed someone often has no deadline in either system. So the honest answer to “how long do they have?” is that you have to look at the specific state’s law, the degree of the offense, and whether federal jurisdiction is in play.
The Federal 10-Year Rule
Federal arson law reaches fires set to property involved in interstate commerce (most businesses, rental property, and commercial vehicles), fires on federal property, and fires used to conceal another federal crime. For non-capital federal arson, prosecutors have 10 years from the date of the offense to file charges.1Office of the Law Revision Counsel. 18 USC 3295 – Arson Offenses That is double the standard five-year federal window that applies to most non-capital crimes.2Office of the Law Revision Counsel. 18 US Code 3282 – Offenses Not Capital
There is a major exception. Federal arson resulting in death can carry the death penalty, which makes it a capital offense.3Office of the Law Revision Counsel. 18 USC 844 – Penalties Capital offenses have no statute of limitations under federal law, so those charges can be brought at any time.4Office of the Law Revision Counsel. 18 USC 3281 – Capital Offenses The 10-year clock only runs when nobody died.
State Deadlines Vary Widely
There is no national state-level deadline for arson. Each state writes its own rule, and the range is wider than most people assume. Some states allow as few as four years to bring charges. Others set the window at five, six, eight, ten, or eleven years. And a significant number of states impose no statute of limitations on arson at all, treating it as serious enough to prosecute at any point.
The unlimited window is most common for first-degree arson or arson that results in death. Even states that do set a deadline for lower-degree arson often eliminate it entirely when the fire kills someone. In practical terms, that means a suspect could be charged decades after a fire if investigators eventually build a case.
You cannot assume a short window applies. The only reliable way to know the deadline is to check the law of the specific state where the fire occurred.
How the Degree of Arson Changes the Clock
Many states tie their limitations period to how the arson is classified.5Cornell Law School. Arson A first-degree charge might have no deadline at all, while a lesser offense involving only property damage might carry a five- or six-year window. The distinction between degrees generally comes down to what was burned, whether anyone was inside, and what the defendant was thinking.
- First-degree arson usually involves setting fire to an occupied building. Because it directly endangers lives, it carries the longest prison sentences and often the longest (or no) limitations period.
- Second-degree arson typically covers unoccupied structures. Still a serious felony, but the absence of people inside generally means lower penalties and a set deadline.
- Third-degree arson usually involves personal property, often set on fire to defraud an insurer. Penalties are lighter and a statute of limitations is more likely to apply.
The required mental state also shifts by degree. Higher-degree arson generally requires proof that the defendant intentionally started the fire with the goal of causing damage. Lower-degree charges sometimes allow prosecutors to prove recklessness instead — that the defendant knew there was a serious risk of fire and ignored it. That difference can determine whether the offense has a time limit at all.
When the Clock Pauses
The statute of limitations does not always run continuously. Both federal and state law recognize situations where the clock stops, a concept lawyers call tolling. The most common trigger is fleeing from justice. Federal law is blunt: no statute of limitations extends to anyone fleeing from justice.6Office of the Law Revision Counsel. 18 USC 3290 – Fugitives From Justice Courts have read this broadly. Physical absence from the jurisdiction is not always required; actively evading law enforcement while staying in the same area can also trigger tolling.7U.S. Department of Justice. Criminal Resource Manual 657 – Tolling of Statute of Limitations
Most states follow similar logic. If a suspect leaves the state after the fire, the clock typically stops for the entire period of absence. Some states pause it whenever the suspect is outside the state for any reason; others require that the absence be linked to avoiding prosecution. A few states also toll the clock when the suspect’s identity is unknown but DNA or other forensic evidence has been preserved.
Tolling matters a great deal in arson cases because the investigation itself often takes years. If the suspect is identified late and has been out of state in the interim, the tolling rules can keep the case alive well past the nominal deadline.
What Happens If the Deadline Passes
If prosecutors miss the statute of limitations, the consequence is straightforward. The defendant can file a motion to dismiss and the court must grant it. This is true even if the evidence is overwhelming. A confession, video footage, and a stack of forensic reports are all worthless once the clock has expired. The dismissal is permanent; prosecutors cannot refile the same charges later.
That is why tolling fights get so much attention. If a prosecutor can show the defendant was a fugitive for part of the limitations period, the effective deadline extends. Defense attorneys, in turn, scrutinize whether tolling was properly applied. A dispute over whether the defendant was genuinely fleeing, versus simply living in another state for personal reasons, can decide whether the case proceeds at all.
Insurance-Fraud Arson Has Its Own Clock
Arson set to collect insurance money adds a second layer of criminal exposure with its own deadline. Beyond the arson charge, a suspect can face federal insurance-fraud charges if the insurer operates across state lines, which most do. Federal law makes it a crime to knowingly make false statements to an insurance company or to embezzle insurance funds, with penalties up to 10 years in prison for the fraud alone, and up to 15 years if the fraud jeopardizes the insurer’s financial stability.8Office of the Law Revision Counsel. 18 US Code 1033 – Crimes by or Affecting Persons Engaged in the Business of Insurance
The fraud charge carries its own statute of limitations, separate from the arson charge. Someone who set a fire for insurance money could face prosecution for the fraud even if the state arson deadline has already passed. Federal prosecutors regularly stack the two.
Separately, insurers can file civil suits to recover fraudulent payouts. Civil deadlines for property claims vary by state but are typically shorter than criminal ones, and they usually run from when the fraud was discovered rather than when the fire happened.
Why Arson Cases Push Against the Deadline
Arson investigations are among the hardest in criminal law, and that is a big part of why these deadlines matter here more than in most crimes. Fire destroys the very evidence investigators need. By the time firefighters finish suppression, the scene has been doused with water, walked through by boots, and exposed to contamination. Determining whether a fire was intentionally set often requires painstaking reconstruction using burn-pattern analysis, accelerant detection, and chemical testing.
Newer, more sensitive detection tools now allow investigators to revisit older cases where earlier testing was inconclusive, which is one reason states have moved toward longer windows (or no window) for serious arson. But witness memory also degrades over time, witnesses move or become unavailable, and details blur within a few years. Statutes of limitations exist partly because the evidence genuinely gets worse with time.
When to Talk to a Lawyer
If you learn you are under investigation for arson, or even suspect you might be, that is the point at which legal representation matters most. An attorney’s first job is often to figure out whether the statute of limitations has any bearing on your situation at all. That requires knowing which state’s law applies, what degree of arson is being investigated, whether federal jurisdiction is in play, and whether any tolling provisions have paused the clock. The difference between a four-year and a ten-year deadline, or between a limited and unlimited window, can decide whether charges are legally possible in the first place.
If charges have already been filed, counsel evaluates the strength of the prosecution’s forensic evidence, looks for procedural errors, and builds a defense. In cases where the fire investigation was flawed or the evidence is thin, that work can lead to reduced charges or dismissal well before trial.
