arson (law) | Definition

Doc's CJ Glossary by Adam J. McKee
Course: Introduction / Criminal Law

At common law, arson was defined as “the malicious burning of the dwelling of another.”


Arson, historically, has been a serious and destructive crime. The common law definition of arson was the “malicious burning of the dwelling of another.” This definition referred to the deliberate and intentional setting of fire to someone else’s home, usually with the intent to harm or destroy the property.

Today, the definition has evolved and is now defined by modern statutes that have been created and adopted by individual states. While arson is still a serious criminal offense, modern statutes tend to grade the severity of the offense based on the value of the property destroyed rather than the type of property, such as a dwelling. For example, a person who sets fire to a home may be charged with a more severe crime than someone who sets fire to a vacant building.

In most jurisdictions, arson is a felony offense that carries serious consequences, including imprisonment and hefty fines. The penalties for it can vary widely depending on the severity of the crime, the value of the property destroyed, and whether anyone was injured or killed as a result of the fire.

The actus reus of arson is the act of setting fire to property. The mens rea varies from jurisdiction to jurisdiction but generally requires a showing of intent or recklessness. For example, a person who intentionally sets fire to a building with the intent to destroy it would be guilty of arson. Similarly, a person who recklessly sets fire to a building, knowing that the fire is likely to spread and cause harm, may also be guilty of arson.

In addition to traditional definitions, some modern statutes also criminalize the act of “aggravated arson,” which involves setting fire to a building or property with the intent to cause harm or injury to others. For example, a person who sets fire to a school with the intent of harming students or staff may be charged with aggravated arson.

Arson is a serious crime that can have devastating consequences for individuals, families, and communities. Not only can arson cause physical harm and financial loss, but it can also create significant emotional trauma for those affected by the crime. As a result, law enforcement officials and prosecutors take arson cases very seriously and work diligently to investigate and prosecute those responsible for these offenses.
