What Is Considered “Arson” Under Penal Code 451 PC?
There are two California statutes pertaining to arson.
- Malicious Arson – California Penal Code 451
- Reckless Burning -Penal Code 452
In this guide I will focus on explaining Penal Code 451 which concerns the more serious one also known as “malicious arson.”1

Malicious pertains to unlawfully committing the act of burning a structure, forest land or property to:
- Injure someone
- Defraud an insurance company
- Damage someone else’s property out of spite, jealousy, annoyance, revenge or any other reason
Malicious arson is composed of the following (2) two elements:
1. The defendant set fire to property2 including any kind of:
- structure,
- motor vehicle,
- forest land or personal property, OR
The defendant assisted, counseled or procured the burning3 of such property4, AND,
2. It was done so willfully and maliciously5
How Does a Prosecutor Prove Arson?
A prosecutor must prove both of the elements mentioned for an arson conviction.

Lets take a look at these terms individually to understand the legal explanation.
(1) First Element – Setting Fire
When you hear of arson, most people assume it concerns the total destruction of land or of a building by fire.

For purposes of committing arson under California law, however, any kind of damage, no matter how minor, satisfies this element of the offense.

What Is Considered A Structure?
A structure may any of the following:
- Be an inhabited or uninhabitable residence,
- Any kind of motor vehicle,
- Tent,
- Business or even a tunnel.
What Is Considered Property?
Property includes any kind of personal property including:
- A stamp collection
- Clothing6,
- Photographs
- Documents
- Appliances or,
- Furniture.
A qualification to this element is that the property that is burned must have belonged to someone other than yourself.
Can You Be Charged For Arson If You Burn Your Own Property?
You can still be charged and convicted if you did burn your own property with the intent to defraud someone or an entity such as burning down your own business for insurance proceeds.

You can also be charged with arson by burning your own property if the fire results in injuring someone or damaging someone else’s property7.
What Is Forest Land?
Forest land refers to grass lands, wetlands, brush, trees or plains.
(2) Second Element—Willful and Malicious Intent
Malicious arson is a crime of specific intent where the requisite mental requirement is of willfulness, meaning purposeful or intentional conduct.
If prosecutors determine you did not set the fire intentionally then they will file misdemeanor reckless burning charges.
Penalties for Penal Code 451 PC – Malicious Arson
Malicious arson under PC 451 is a felony with state prison time.
The length of your sentence depends on the circumstances of the arson and what was burned.
- 16 months, 2 or 3 years if you burned your own property but someone else’s property was damaged8
- 2, 4 or 6 years if a non-inhabited structure or forest land was burned9
- 3, 5 or 8 years if an inhabited building was burned10
- 5, 7 or 9 years in state prison if someone suffered great bodily injury as a result of the arson.11
Additional Penalties Include:
- Fine of up to $10,000, or a fine of $50,000 or twice the amount of your expected financial gain for defrauding someone or entity
- A strike on your criminal record under California’s 3-Strikes law
- Registration as an arson offender for life if convicted as an adult12
Sentencing Enhancements For Penal Code 451
Under penal code 451 the court can impose longer prison sentences known as enhancements if certain aggravating circumstances exist.
These aggravating circumstances include any one of the following:
- Having a prior felony conviction for arson under PC 451 or 452
- A police officer, firefighter or emergency personnel suffered great bodily injury as a result of the fire
- At least 2 people suffered great bodily injury because of the fire
- More than one structure was damaged in the fire
- You used a device to delay the ignition to set the fire or to accelerate it
What Is The Additional Penalty For These Enhancements?
If any of these were present, then the court can impose another 1 to 5 years in state prison to be served consecutively, which means that it is added to your sentence and is not concurrent.

Also, the court may sentence you to a maximum term if you burned the building in retaliation for some perceived wrong committed by the owner of the building or structure.
Is There A Sentencing Enhancement For Burning A House Of Worship?
You face a maximum term if you knew the building you were setting fire to was a place of worship such as a mosque, synagogue or church.

Finally, the court can impose a sentence of 10 years to life when you set the fire with the malicious intent to injure someone or damage an inhabited structure and any of the following circumstances exist:
- You have a prior arson conviction within the past 10 years
- The value of the property damaged by the fire and any other losses or costs associated with it including the cost of containing and extinguishing it was more than $5,650,000
- More than 5 structures were damaged
Legal Defenses For Arson
The following are some common legal defenses that may be used in arson cases.
It Was An Accident
Most defenses center around the explanation that the fire was caused by accident.

If the fire was caused by accident than there was no malicious intent on the part of the defandant and the worst you might face is reckless burning under PC 452.
The DA has to prove you had the willful intent to start the fire and will need proof of motive or corroborating testimonial or documentary evidence to convict you.
Some fires are caused unintentionally but the defendant created a high risk or possibility that a fire would either occur or damage other property or injure other persons.
Examples Include:
- Persons who were impaired or intoxicated and allowed a campfire to burn out of control.
- A person passed out in an apartment while smoking.

Because the individuals passed out or were too intoxicated, the argument is that they were incapable of understanding or appreciating the risk.
The Prosecution Has Insufficient Evidence
It is difficult to prove intent in starting a fire unless there is direct or circumstantial evidence.
Such evidence might include:
- Discovering that you did computer research on how to surreptitiously start a fire.
- The existence of a motive based on financial problems.
- Revenge for being unjustly terminated from a job.
- Finding containers of gasoline or accelerants in your garage.
- Witnesses who can testify they saw you running from the scene just before the fire began.
What Is Considered Direct Evidence?
Direct evidence is someone testifying that they saw you start the fire.

What Is Circumstantial Evidence?
Circumstantial evidence is proof of a fact from which a person may reasonably infer or conclude that you committed the crime.
Such as incriminating internet searches found on your computer.

Reasonable alternatives for certain evidence that do not point to or infer guilt must be considered by the trier of fact.
Circumstantial evidence is treated the same as direct evidence and can be powerful even though it is not direct evidence.
If there is enough circumstantial evidence and it is convincing enough, it can convict a defendant.
Immigration Consequences
A conviction under PC 451 is a serious felony and a deportable offense if you are not a US citizen. It is considered a crime of moral turpitude.
If you left the country after your conviction, you will be unable to reenter. Also, if you are a legal resident, your opportunity for naturalization is seriously compromised.
You can still seek relief from removal proceedings if you qualify for deferred action, adjustment of status or under temporary protected status.
