Penal Code § 148.4 PC – False Fire Alarm or False Report of a Fire – California Law

California Penal Code § 148.4 PC defines the crime of making a false fire alarm or false report of a fire. The offense is a misdemeanor punishable by up to 1 year in jail and fines of up to $1,000.00.

There are three ways to violate this law:

1. you tamper with or break a fire alarm or fire protection equipment (such as fire extinguishers),
2. you trigger a false fire alarm, or
3. you make a false report of a fire.

The offense is a misdemeanor punishable by up to 1 year in jail and fines of up to $1000.00.

The full text of the code section reads:

1. When is making a false fire alarm a crime?

Under California law, a district attorney must prove the following to convict you under this statute successfully:

1. you tampered with or broke a fire alarm or type of fire protection equipment,
2. you triggered a false fire alarm, or
3. you made a false report of a fire.¹

In addition to the above, a prosecutor must show that you acted both willfully and maliciously.

You act “willfully” when you commit an act willingly or on purpose.²

You act “maliciously” when you act with an intent to:

• do a wrongful act, or
• annoy or injure a person.³

2. What are the best defenses to Penal Code 184.4 PC?

Our defense attorneys advise that there are three effective defenses to allegations of making a false report of a fire. These are showing that you:

1. did not act willfully,
2. did not act maliciously,
3. were falsely accused.

2.1 No willful act

You are guilty under this statute only if you acted willfully. Therefore, it is always a defense to show that you did not act with this aim. Perhaps, for example, you committed an act on accident.

2.2 No malicious act

A prosecutor must show that you acted maliciously to secure a conviction under these laws. It is always a defense, then, to show that you did not act with malice. Perhaps, for example, you acted with a reasonable belief (although mistaken) that there was an actual fire.

2.3 Falsely accused

You can challenge an allegation by showing that another person falsely accused you of breaking the law. False accusations are not uncommon when it comes to this offense. A person might unjustly blame you out of:

• jealousy,
• revenge, or
• anger.

3. What are the penalties?

Most violations of this law are charged as misdemeanors.⁴

The crime is punishable by:

• imprisonment in county jail (as opposed to state prison) for up to one year, and/or
• a maximum fine of one thousand dollars.⁵

A judge does have the authority to award you with misdemeanor (or summary) probation in lieu of jail time.

Note, though, that if you break this law and it causes great bodily injury or death to another, then the offense:

• becomes a felony, and
• becomes punishable by up to three years in jail and/or a fine between five hundred dollars and ten thousand dollars.

4. Can I get a PC 148.4 conviction expunged?

If you are convicted of a misdemeanor crime under this statute, you can get a conviction expunged provided that you successfully complete:

• a jail term, or
• probation (whichever was imposed).

You can also get a felony conviction expunged unless it leads to a term in state prison.

5. Are there related offenses?

The following crimes are related to making a false fire alarm:

1. false report of an emergency – PC 148.3,
2. making a false police report of a crime – PC 148.5, and
3. false identification to a police officer – PC 148.9

5.1 False report of an emergency – PC 148.3

Penal Code 148.3 PC is the California statute that makes it a crime to make a false report of an emergency.

Note that while PC 148.4 focuses specifically on fires, this statute applies to emergencies in general.

5.2 Making a false police report of a crime – PC 148.5

Penal Code 148.5 PC is the California statute that makes it illegal to make a false police report of a crime.

Like PC 148.4, a violation of this law can be charged as either a misdemeanor or a felony depending on the facts of the case.

5.3 False identification to a police officer – PC 148.9

Penal Code 148.9 PC is the California statute that makes it a crime knowingly to provide false identification to a peace officer.

While Penal Code 148.4 focuses on fire alarms, equipment, and reports, this statute centers on false identification (for example, a wrong name).
