Definition
Arson is the willful and malicious burning of the dwelling house or outhouse of another person. At common law, arson was a felony requiring three elements: (1) a burning, (2) of another's dwelling or appurtenant structure, (3) accomplished willfully and maliciously. The offense protected habitation — the safety of persons in their homes — rather than property in the abstract. Modern statutes have significantly expanded the offense, extending it beyond dwellings to commercial buildings, vehicles, and other structures, and subdividing the offense into degrees based on the type of structure, whether it was occupied, and the risk to human life.
Common Language
Modern common usage (Wiktionary): A saddlebow.
Historical common usage (Webster's 1913): The malicious burning of a dwelling house or outhouse of another man, which by the common law is felony; the malicious and voluntary firing of a building or ship.
The Wiktionary entry for "arson" captures a homophone or archaic alternate term unrelated to the criminal offense. Webster's 1913 tracks the legal meaning closely, as arson has no meaningful life outside criminal law. Researchers should be aware that the term has no dual common/legal usage problem — the legal definition is the definition.
Core Elements
At common law, arson required:
1. BURNING: Actual ignition and charring of the structure was required. Scorching or blackening without actual burning of the material of the building was insufficient. Burrill notes that "the burning and consuming of any part is sufficient," but a mere attempt to set fire, resulting in no actual combustion of the structure, did not constitute the completed offense.
2. DWELLING HOUSE OR OUTHOUSE: The target was the home — not merely the physical structure but the place of habitation. Outhouses and appurtenant structures that were part of the dwelling were included. Black's (2nd Ed.) confirms the word "house" encompassed "all outhouses which are parcel thereof."
3. OF ANOTHER: Common law arson required the structure to belong to another person. A man could not commit arson by burning his own house, even maliciously, at common law — though many modern statutes have eliminated or reversed this requirement, particularly when occupants, neighbors, or insurers are endangered.
4. WILLFULLY AND MALICIOUSLY: The burning had to be intentional and without legal justification. Accident or negligence, however gross, did not satisfy the element. Malice did not require personal ill will toward the owner; general willful disregard of the probable consequences sufficed.
Recognized Forms
/SUBTYPES
COMMON LAW ARSON: Limited to the dwelling house and appurtenant structures of another, as described above.
STATUTORY ARSON — FIRST DEGREE: Typically the burning of an inhabited dwelling or structure with persons present; most severely punished.
STATUTORY ARSON — SECOND DEGREE: Burning of uninhabited structures, or inhabited structures where no persons are present at the time.
STATUTORY ARSON — THIRD DEGREE (where recognized): Burning of personal property, vehicles, or structures of lesser character, often including one's own property for fraudulent purposes.
ATTEMPTED ARSON: The setting of fire or preparation therefor without completion of the burning; addressed by statute in most jurisdictions.
Why It Matters in Research
The single most important navigational point for researchers working in the Law Mind corpus is the gap between common law arson and modern statutory arson. Historical sources — including all five shelf dictionaries here — define arson exclusively around the dwelling of another. A researcher reading nineteenth-century cases or indictments should not assume that the burning of a commercial warehouse, barn without residential function, or the defendant's own property was indictable as arson at common law; it may have been charged under separate incendiarism or malicious mischief statutes instead.
The ownership element is a significant trap. Because common law arson required the structure to belong to another, co-owners, landlords burning their own tenanted property, and owners burning for insurance presented doctrinal complications that courts handled inconsistently. Statutory reforms addressed this, but the timeline of those reforms varies by jurisdiction.
The "degrees" structure mentioned by Anderson's is a nineteenth-century American statutory innovation. When researching across states, researchers should identify whether a given jurisdiction had adopted degree-based arson statutes and when, as the same conduct might be first-degree arson in one state and not arson at all in another during the same period.
The burning element's threshold — charring versus mere scorching — was actively litigated. Cases turning on whether sufficient combustion occurred to constitute the completed offense appear frequently in criminal law reporters. Researchers encountering acquittals or reduced charges in arson prosecutions should consider whether the burning element, not intent, was the contested issue.
Historical Dictionary Support
The five shelf sources are in close agreement, reflecting the stability of common law arson's definition across the period they cover. All five center on the willful and malicious burning of another's dwelling. Burrill provides the most complete treatment, noting the sufficiency of burning any part of the structure and distinguishing the completed offense from mere attempt. Burrill also supplies the Latin and Old French etymology (arsion, arsoun; from ardere, to burn), which is useful for tracing the term in medieval and early modern sources.
Black's (both editions) and Rapalje & Lawrence offer the standard formulation without meaningful elaboration beyond citing Stephens' Commentaries and Russell on Crimes. Anderson's is the most practically oriented, noting explicitly that some states had already moved to degree-based statutes and extending the common law rule to cover buildings so situated as to endanger a dwelling even if not themselves dwellings. This last formulation — arson by proximity or endangerment — is an important transitional doctrine bridging the common law dwelling requirement and modern property-based statutes.
None of the historical sources address arson of one's own property, insurance fraud arson, or vehicular arson, which are creatures of twentieth-century statutory development and entirely outside their frame.
Jurisdictional Note
The common law definition — requiring the structure to be a dwelling of another — was modified at different times and in different ways across American jurisdictions. Most states now define arson to cover any building or structure regardless of ownership, and many include vehicles, personal property, and wildland. Federal arson statutes address specific federal interests including federal property and arson in aid of racketeering. Researchers should not assume uniformity even within modern statutory frameworks.
