11.6 Arson
Key Takeaways
- Common law arson is the malicious burning of the dwelling of another, and malice means reckless disregard of an obvious risk rather than ill will.
- There must be actual charring, meaning damage to the fibre of the structure, so mere blackening, scorching, or smoke damage is insufficient.
- Because the dwelling had to be another's, burning one's own house was not common law arson, a gap modern statutes close through separate offenses such as houseburning and insurance fraud.
- Modern statutes extend arson to any structure or personal property and frequently include damage caused by explosion.
- Arson is a malice crime rather than a specific intent crime, so voluntary intoxication is not a defense to it.

Arson
1. Common Law Arson: The Strict Combustion Standard
Common Law Definition
At common law, arson is defined as the malicious burning of the dwelling house of another.
Arson is a malice crime (one of only two at common law, alongside murder). It requires proof of four elements:
[ Malice ] + [ Burning (Combustion) ] + [ Dwelling House ] + [ Of Another ] = Common Law Arson
Element 1: Malice
Malice does not require ill-will, spite, hatred, or a specific intent to destroy the building. Malice is established if the defendant acted with:
- An intent to burn the dwelling house; OR
- A reckless disregard of an obvious and substantial risk that the structure would catch fire.
- Negligence Insufficient: Accidental fires resulting from ordinary or gross negligence do not constitute common law arson.
- Defenses: Because arson is a malice crime, voluntary intoxication is NO defense. Furthermore, mistake of fact must be both honest and reasonable.
Element 2: Burning (The Charring vs. Scorching Rule)
The most frequently tested issue in arson is whether the fire produced sufficient physical destruction to constitute a "burning":
- Actual Combustion of Structural Material: There must be actual combustion—a chemical change and wasting—of some portion of the fiber of the structure itself (e.g., wooden siding, structural joists, flooring, or framing).
- The Threshold of Charring: Charring (carbonization of wood fibers) is sufficient to consummate arson. The fire does not need to spread, the damage need not be extensive, and the building does not need to be consumed or structurally compromised.
- Insufficient Physical Damage for Arson:
- Smoke and Soot Damage: Discoloration, smoke odors, and heavy soot deposits do not constitute burning.
- Scorching and Blistering of Paint: Blistering, discoloration, or peeling of surface paint or wallpaper without any combustion or charring of the underlying structural wood fibers does NOT constitute arson.
- Blackening of Surface: Mere blackening of the wall surface by heat without wasting of the wood fiber is insufficient.
| Physical Result of Fire | Structural Fiber Consumed? | Common Law Arson? | Proper Common Law Offense |
|---|---|---|---|
| Soot & Smoke Discoloration | No | No | Criminal Mischief / Malicious Mischief |
| Blistering & Peeling of Paint | No | No | Attempted Arson / Criminal Mischief |
| Slight Charring of Floorboards | Yes | YES | COMMON LAW ARSON |
| Wood Wall Carbonized / Burned | Yes | YES | COMMON LAW ARSON |
Element 3: Of the Dwelling House
Like common law burglary, arson protected the security of habitation:
- The structure had to be a dwelling house (place of regular sleeping) or an outbuilding within the immediate curtilage.
- Burning commercial structures, ships, or personal property was not common law arson (punished instead as common-law misdemeanors).
Element 4: Of Another
Arson protects the occupant's security, not legal ownership:
- Burning One's Own House: Burning one's own dwelling house—even if done intentionally to collect insurance proceeds—was NOT common law arson. (If burning one's own house created a danger to neighboring dwellings, it was punished as the misdemeanor of houseburning).
- Landlord vs. Tenant: A tenant in lawful possession who burned the leased house did not commit common law arson (because it was the tenant's dwelling, not "of another"). Conversely, a landlord who burned a house leased to and occupied by a tenant committed common law arson against the tenant.
2. Modern Statutory Arson & Degrees
Modern statutes have completely overhauled common-law arson, expanding both the property covered and the culpability standards:
- Expanded Property Categories: Modern arson encompasses all commercial buildings, industrial warehouses, schools, churches, vehicles, watercraft, crops, forest lands, and personal property.
- Burning Own Property: Under modern codes (including California Penal Code § 451), an owner who maliciously burns their own property with the intent to defraud an insurance company is guilty of felony arson.
- California Penal Code Framework:
- Cal. Penal Code § 451 (Arson): Willfully and maliciously setting fire to, burning, or causing to be burned any structure, forest land, or property. Penalties are graduated based on whether great bodily injury is caused, whether an inhabited structure is burned, or whether commercial/personal property is involved.
- Cal. Penal Code § 452 (Unlawfully Causing a Fire): Punishes recklessly setting fire to, burning, or causing to be burned any structure, forest land, or property. This serves as a lesser-included offense to malicious arson.
3. Master Comparison Table: Property & Habitation Crimes
| Offense | Category | Actus Reus | Target Property | Mens Rea Standard | Critical FYLSE Distinction |
|---|---|---|---|---|---|
| Common Law Burglary | Habitation | Breaking and entering | Dwelling house of another at night | Specific intent to commit a felony | Felonious intent must concur with the exact moment of entry. |
| Modern Burglary (CPC § 459) | Property / Structure | Unauthorized entry or remaining | Any building, room, vessel, or locked vehicle | Specific intent to commit theft or any felony | Breaking and nighttime abolished; applies to open commercial stores. |
| Common Law Arson | Habitation | Burning (actual combustion / charring) | Dwelling house of another | Malice (intent or reckless disregard) | Scorched paint is insufficient; requires charring of structural fiber. |
| Modern Arson (CPC § 451) | Property / Safety | Burning or setting fire to | Any structure, forest land, or property | Willful and malicious | Includes burning one's own property to defraud insurance. |
| Robbery | Person & Property | Taking and asportation by force or fear | Personal property from person/presence | Specific intent to permanently deprive | Force must be immediate; force used to escape elevates taking to robbery. |
| Extortion | Property | Coerced transfer of property | Any property | Specific intent to wrongfully acquire | Involves threats of future harm, criminal accusation, or scandal. |
Test Your Knowledge
Angry over an eviction notice, a tenant deliberately splashes gasoline across the exterior wooden siding of the rented single-family home. The tenant ignites the gasoline, creating a sudden fireball. The flames scorch and blister the exterior oil-based paint and deposit a thick coating of black soot across the wall before a passing neighbor extinguishes the fire with a garden hose. Forensic inspection reveals that while the exterior paint was ruined and the surface heavily blackened, the underlying structural wood siding was not burned, charred, or consumed in any degree. Under traditional common law rules, what offense has the tenant committed?
