California bill creates criminal and civil penalties for knowingly false emergency reports

Establishes misdemeanor and felony offenses for false emergency reports, defines “emergency,” and makes reporters liable for agency response costs and property damage.

The Brief

This bill makes it a crime to knowingly report — or cause the reporting of — a false “emergency” to city, county, or state entities. It creates a baseline misdemeanor for a knowingly false report, an escalator for repeat incidents that produce unnecessary responses, and a felony where the false report foreseeably leads to death or great bodily injury.

The statute also defines “emergency” for the purpose of the offense and expressly exempts certain good-faith parental reports about missing children.

Beyond criminal sanctions, the bill gives public agencies and affected private parties a civil route to recover reasonable emergency-response costs and property-damage losses caused by a false report. The measure is aimed at deterring hoaxes and frivolous 911-style activations, but it also raises practical questions about proof, cost calculation, and the potential chilling effect on legitimate emergency calls.

At a Glance

What It Does

The bill criminalizes knowingly false reports of an “emergency” to local or state agencies, with a misdemeanor for a first offense, enhanced penalties for repeat offenses that cause unnecessary responses, and a felony where the false report is likely to cause death or great bodily injury and such harm results. It defines what counts as an emergency and allows agencies and private parties to recover reasonable response costs and property damage.

Who It Affects

Emergency dispatch centers, law enforcement and fire agencies, local governments that bear response costs, prosecutors and courts, and members of the public who call or cause emergency reports. It will also affect individuals who make malicious or reckless false reports and private parties that sustain property damage during an emergency response.

Why It Matters

The bill gives agencies a statutory deterrent and a civil recovery tool for misuse of emergency resources, which states previously addressed piecemeal. For practitioners, it creates new proof issues (mens rea and foreseeability), administrative burdens to calculate recoverable costs, and potential policy conflicts between deterrence and ensuring prompt reporting of genuine emergencies.

What This Bill Actually Does

The bill makes it a misdemeanor to knowingly report, or to cause a report that a situation is an “emergency,” to a city, county, or state department or agency. A conviction can carry up to one year in county jail and a monetary fine.

The statute elevates the risk if the conduct repeats: a second or subsequent knowingly false report that results in an unnecessary emergency response can carry the same jail and fine exposure and, under the statute’s cross-reference, may be punishable under the sentencing rule identified in Section 1170(h). The bill carves out an exception so that the escalator does not apply based on prior offenses committed when the offender was under 18.

For more serious consequences, the bill creates a felony where an individual knowingly makes a false emergency report and either knows or should know that the response is likely to cause death or great bodily injury, and such death or great bodily injury actually occurs as a result. That felony exposure includes imprisonment under the statutory sentencing rules the bill references and a fine up to $10,000.The bill supplies a working definition of “emergency”: situations that produce a response by public officials in authorized emergency vehicles, aircraft, or vessels; situations that jeopardize public safety and could require evacuation of places people may enter; or activations (or potential activations) of the Emergency Alert System under Government Code Section 8594.

Importantly, the definition excludes Emergency Alert System activations that are based on a parent, guardian, or lawful custodian’s good-faith report that a child is missing.Finally, the measure establishes civil liability tied to a criminal conviction: someone convicted under the statute who caused an emergency response is liable to the public agency for the reasonable costs of that response and liable to other parties for property damage sustained because of the response. The bill also states it does not prevent application of any other law that provides for greater punishment, preserving prosecutorial flexibility to pursue other offenses where appropriate.

The Five Things You Need to Know

1

The bill makes a knowingly false emergency report a misdemeanor punishable by up to one year in county jail, a fine up to $1,000, or both.

2

A second or subsequent knowingly false report that causes an unnecessary emergency response can be punished under the same misdemeanor caps or under the sentencing structure referenced in Penal Code Section 1170(h); the repeat-offense escalator does not apply if the prior offense was committed when the defendant was under 18.

3

The bill creates a felony when a knowingly false report foreseeably risks death or great bodily injury and such death or great bodily injury actually results; the felony carries potential imprisonment under Section 1170(h) and a fine up to $10,000.

4

“Emergency” is defined broadly to include responses by authorized emergency vehicles, evacuations that jeopardize public safety, and activations of the Emergency Alert System; however, EAS activations based on a parent’s good-faith report that a child is missing are exempted.

5

A conviction makes the defendant civilly liable to public agencies for the reasonable costs of the emergency response and to other parties for property damage caused by the response.

Section-by-Section Breakdown

Every bill we cover gets an analysis of its key sections. Expand all ↓

Section 148.3(a)(1)

Baseline misdemeanor for knowingly false emergency reports

This subsection creates the core offense: an individual who knowingly reports—or causes a report that—an "emergency" exists to a city, county, or state entity commits a misdemeanor. The practical effect is to criminalize intentional hoaxes and false alarms directed at public agencies. Prosecutors will need to prove both that the report was false and that the defendant had the requisite knowledge that it was false.

Section 148.3(a)(2)

Repeat-offense escalator and youth exception

A second or subsequent violation that results in an unnecessary emergency response triggers a sentencing escalator: the same misdemeanor caps remain available, but the provision also permits imprisonment pursuant to subdivision (h) of Section 1170. The subsection exempting prior offenses committed while the defendant was under 18 narrows the escalator’s reach for juvenile histories, but adult repeat offenders face a clear statutory path to harsher custody exposure.

Section 148.3(b)

Felony where foreseeability and serious harm align

This subsection elevates the conduct to a felony when the defendant knowingly makes a false report and either knows or should know the response is likely to cause death or great bodily injury, and such harm results. The statutory language imports a foreseeability standard (“knows or should know”) for the dangerousness element, increasing the prosecution’s burden to show the defendant’s awareness or objective foreseeability about the likely severity of the response.

Section 148.3(c)

Definition of ‘emergency’ and parental exemption for EAS reports

The bill defines “emergency” to cover conditions that prompt an authorized emergency-vehicle response, situations that could require evacuation, and activations of the Emergency Alert System under Government Code Section 8594. The statute also provides a targeted exemption: an EAS activation driven by a parent, guardian, or lawful custodian who in good faith believes a child is missing does not count as an “emergency” for this offense—protecting common missing-child reports from criminal liability.

Section 148.3(d)

Nonexclusivity of punishments

Subdivision (d) states that the statute does not preclude imposing greater punishment under other laws. Practically, this preserves prosecutors’ ability to charge other overlapping offenses—aggravated assault, arson, or other statutes—if the facts support higher penalties, rather than forcing exclusive reliance on the false-report statute.

Section 148.3(e)

Civil liability for response costs and property damage

A conviction under the section creates civil liability: the convicted individual is liable to the public agency for the agency’s reasonable emergency-response costs and liable to any other party for property damage caused by the response. The provision does not define “reasonable costs,” leaving agencies and courts to sort out what components of a response (personnel time, equipment usage, overhead) are recoverable and how to calculate them.

Who Benefits and Who Bears the Cost

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.

Who Benefits

  • Emergency responders and dispatch centers — Reduced deliberate misuse of scarce resources and a statutory basis to deter hoaxes should lower unnecessary responses and allow crews to focus on genuine emergencies.
  • Local governments and public agencies — The civil-liability provision creates a route to recover at least some costs from persons who cause avoidable deployments, shifting some fiscal burden away from taxpayers.
  • Private parties harmed during a response — Individuals or businesses whose property is damaged because of a false report can seek compensation from a convicted reporter, providing a remedy that currently may be cumbersome or unavailable.

Who Bears the Cost

  • Individuals who knowingly make false reports — Face criminal exposure (misdemeanor or felony), fines, and civil liability for agency costs and property damage.
  • Local agencies and municipalities — Must develop processes to calculate and document “reasonable” response costs, pursue civil claims, and allocate staff time to support prosecutions and cost recovery actions.
  • Prosecutors and courts — Will take on additional evidentiary burdens to prove knowledge and foreseeability, and may see increased caseloads as agencies seek criminal and civil enforcement.

Key Issues

The Core Tension

The bill strikes at a fundamental trade-off: it aims to deter costly, dangerous hoaxes and give agencies a pathway to recover expenses, but doing so risks discouraging timely, legitimate calls for help and requires agencies and courts to resolve difficult proof and cost-allocation questions that could blunt the statute’s effectiveness.

The statute sets out clear deterrent aims but leaves several operational and legal questions open. Proving the mental-state elements will be central and potentially difficult: the misdemeanor requires “knowing” falsity, while the felony hinges on what the defendant “knows or should know” about the likely risk of death or great bodily injury.

That hybrid of subjective and objective standards will generate contested factual inquiries about what a defendant actually believed versus what a reasonable person should have foreseen.

The civil-cost recovery language likewise invites disputes. The bill makes a convicted defendant liable for a public agency’s “reasonable costs,” but it does not define that term or set a procedure for billing, challenging, or collecting costs.

Agencies will need to decide whether to pursue administrative billing, civil actions, or include costs in criminal restitution; each path has different evidentiary and collection implications. There’s also a real risk of chilling legitimate emergency reporting: callers who are uncertain, non-native English speakers, those with mental-health crises, or Good Samaritans might fear criminal exposure, and dispatch centers may face increased scrutiny and second-guessing for discretionary response decisions.

Finally, the parental exemption for EAS activations protects a common, sensitive category of reports but is framed narrowly (limited to EAS activations and to reports by parents/guardians made in good faith). Agencies and courts will need to interpret “good faith belief” and reconcile borderline situations.

The statute’s cross-reference to Section 1170(h) for sentencing raises additional procedural questions about custody placement and sentencing mechanics that will require local prosecutorial and judicial guidance.
