AB 1872 criminalizes knowingly false reports that an “emergency” exists to city, county, or state entities, with misdemeanor penalties for a first offense and elevated penalties for repeat offenders. It also creates a felony for false reports that foreseeably produce a response likely to cause death or great bodily injury when such harm actually occurs.
The bill defines “emergency” broadly (including events that could trigger the Emergency Alert System), carves out good-faith reports by parents or guardians about missing children, and allows public agencies and harmed third parties to recover reasonable emergency response costs and property damages from convicted reporters. For compliance officers and public safety managers, the measure adds criminal exposure for false reporting and a new pathway to recover response costs; for courts and agencies it creates new enforcement and administrative tasks around prosecutions and cost claims.
At a Glance
What It Does
The bill makes it a misdemeanor to knowingly report a false emergency to local or state public bodies and a felony where the false report foreseeably risks deadly or grievous harm and such harm occurs. It defines what counts as an “emergency,” excludes good-faith missing-child reports by parents/guardians, and authorizes civil liability for response costs and property damage.
Who It Affects
Individuals who contact government entities to report emergencies; local and state public safety agencies that respond to such reports; courts that will process criminal cases and civil cost claims; and private parties who suffer property damage because of a false-report response.
Why It Matters
The bill pairs criminal deterrence with a financier-of-last-resort mechanism for agencies and injured third parties to recover costs, changing the legal and administrative stakes of false alarms. It also broadens the statutory definition of emergencies to include potential triggers for statewide alert systems, which affects how agencies decide to respond.

What This Bill Actually Does
AB 1872 targets people who knowingly trigger an emergency response by reporting a false emergency to municipal or state governmental bodies. For a first offense the bill sets criminal liability as a misdemeanor, with statutory maximum penalties; the bill escalates punishment for repeat offenders and creates a felony tier when a false report both is likely to cause a deadly or grievous response and someone actually suffers death or great bodily injury.
The text separates the baseline wrongdoing (knowingly making a false report) from the higher culpability tier that depends on both foreseeability and actual harm.
The measure supplies a compact definition of “emergency”: it covers conditions that bring an authorized emergency response (vehicles, aircraft, vessels), situations that threaten public safety and could require evacuation, and circumstances that could trigger the Emergency Alert System under Government Code Section 8594. The bill explicitly excludes EAS activations that stem from a parent, guardian, or lawful custodian's good-faith report that a child is missing, narrowing the reach of the EAS language for that specific scenario.On remedies, AB 1872 preserves the possibility of charging the same conduct under other laws with greater penalties, and it adds civil exposure: a person convicted under this section is liable to public agencies for the reasonable costs of the emergency response and to other parties for property damage caused by that response.
That civil channel is separate from the criminal penalties and creates an avenue for agencies and private parties to recover expenses and losses occasioned by false reports.Practically, the bill will push prosecutors to establish both the defendant’s knowledge that the report was false and, in the higher tier, that the defendant knew or should have known the response could cause death or great bodily injury and that such harm in fact occurred. Agencies that run alert systems or dispatch responders must consider the new cost-recovery tool and how they document response expenses; victimized property owners gain an explicit statutory basis to claim damages tied to false-report responses.
The Five Things You Need to Know
A first violation is a misdemeanor punishable by up to one year in county jail, a fine up to $1,000, or both.
A second or subsequent violation can be punished by the same misdemeanor penalties or by imprisonment pursuant to subdivision (h) of Section 1170, with a carve-out that excludes prior offenses committed by someone under 18.
The bill creates a felony when the reporter knows the report is false, knows or should know the response is likely to cause death or great bodily injury, and such death or great bodily injury actually occurs; that felony carries imprisonment pursuant to Section 1170(h) and a fine up to $10,000 (or both).
The statutory definition of “emergency” covers events that could trigger an authorized emergency response or activation of the Emergency Alert System under Gov. Code §8594, but excludes EAS activations based on good-faith missing-child reports by parents/guardians.
A person convicted under this section is civilly liable to public agencies for reasonable emergency-response costs and to other parties for property damage resulting from the response.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Misdemeanor for knowingly false emergency reports; repeat-offender penalty
This subsection makes it a misdemeanor to knowingly report—or cause a report to be made—to a city, county, city and county, or state entity that an “emergency” exists. It sets the baseline criminal exposure (up to one year in county jail and/or a fine not exceeding $1,000). It then provides for harsher treatment on repeat violations by authorizing imprisonment pursuant to subdivision (h) of Section 1170 in addition to the misdemeanor sentencing options, and it expressly prevents applying that repeat-offender escalation to prior offenses committed when the defendant was under 18. Practically, prosecutors will need to plead and prove prior convictions to seek the escalated sentence and will rely on the statutory cross-reference to Section 1170(h) to determine the exact confinement terms.
Felony when false report foreseeably risks and causes serious harm
This provision raises the stakes when a false report is not merely deceptive but also dangerous: if the defendant knows the report is false and knows or should know that the expected response is likely to cause death or great bodily injury—and someone sustains such injury—the conduct becomes a felony. The bill ties felony imprisonment to Section 1170(h) and increases the maximum fine to $10,000. Note the mixed mens rea language: the statute requires actual knowledge of falsity but allows liability where the reporter ‘knows or should know’ about the foreseeable risk of severe harm, which creates a hybrid mental-state test that will shape proof strategies.
Definition of ‘emergency’ and EAS carve-out for good-faith missing-child reports
The bill defines ‘emergency’ to include conditions that bring an authorized emergency response, situations that could require evacuation, and circumstances that could trigger activation of the Emergency Alert System per Gov. Code §8594. Importantly, it excludes EAS activations that result from a parent, guardian, or lawful custodian’s good-faith report that a child is missing. That carve-out narrows one operational consequence of the EAS language and signals legislative concern not to chill parents’ good-faith missing-child reports.
No bar to charging under other statutes with greater penalties
This short clause preserves prosecutorial discretion to pursue other charges that carry heavier penalties for the same underlying conduct. In practice, it means law enforcement and prosecutors can choose to charge false-reporting conduct under alternate statutes (for example, statutes governing specific kinds of threats or public endangerment) if those provide higher maximum penalties or different sentencing frameworks.
Civil liability for emergency response costs and property damage
Subdivision (e) makes a convicted false reporter financially responsible for the reasonable costs incurred by public agencies in responding to the false incident and for property damage sustained by third parties as a result of the response. This provision creates a statutory basis for agencies and private parties to pursue cost recovery or damage claims tied to the criminal conviction; it also raises operational questions about how agencies will document and invoice ‘reasonable costs’ and whether they will pursue civil remedies in addition to criminal prosecution.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Local and state public safety agencies — gain an explicit statutory basis to recover reasonable emergency-response costs from convicted false reporters, which can help offset the fiscal burden of wasted deployments.
- Emergency responders and first responders — benefit from a statutory deterrent against malicious or reckless false reporting that diverts resources and endangers personnel.
- Private property owners and third parties harmed by a response — obtain a specific cause of liability to recover property damage caused by emergency actions triggered by a false report.
- Prosecutors and law enforcement — receive a narrowly tailored criminal statute to target non-credible, harmful false reports with graduated penalties and a felony option when the false report produces severe harm.
Who Bears the Cost
- Individuals who knowingly make false emergency reports — face misdemeanor or felony exposure, potential jail time, fines, and civil liability for response costs and property damage.
- Local governments and public agencies — will incur administrative and litigation costs to document, pursue, and enforce civil cost recovery and may need to develop billing practices and recordkeeping systems to support ‘reasonable costs’ claims.
- Courts and public defenders — will experience additional caseload and complexity as prosecutions require proof of knowledge, foreseeability standards, and causation for harm, increasing litigation resources.
- Families and good-faith reporters near ambiguous situations — may experience increased caution or hesitancy to report ambiguous threats if implementation or messaging is not careful, imposing an indirect social cost.
Key Issues
The Core Tension
The central dilemma is between deterring malicious or reckless false emergency reports (and making callers financially pay for the real costs and harms they impose) and avoiding overcriminalization or chilling of legitimate, uncertain, or mistaken reports; the bill boosts accountability but leaves open how to distinguish culpable conduct from genuine mistakes in high-stress situations, and how to administer cost recovery without imposing undue burdens on defendants or local agencies.
The bill mixes mens rea standards in ways that will complicate proof. Subdivision (a) requires proof that the reporter knew the report was false, while subdivision (b) requires knowledge of falsity plus that the reporter ‘knows or should know’ the response is likely to cause death or great bodily injury; courts and prosecutors will confront questions about the ‘should know’ standard and whether it imports negligence or a higher objective foreseeability test.
Establishing causation between a false report and subsequent death or injury will also be fact-intensive: prosecutors must link the report to the chain of events leading to harm and show the harm was a reasonably foreseeable consequence.
The civil-cost recovery scheme creates practical and legal frictions. Agencies must determine what counts as ‘reasonable costs,’ maintain contemporaneous records, and decide whether to pursue civil recovery only after a criminal conviction; smaller jurisdictions may lack capacity to litigate cost claims or may choose not to pursue them, undermining uniform application.
There is also a potential for double punishment concerns and collateral consequences: a defendant faces criminal sentences plus monetary obligations without clear procedural guidance on how costs are calculated, collected, or contested. Finally, while the EAS carve-out for good-faith missing-child reports protects a narrow category of callers, the broader inclusion of potential EAS activations in the emergency definition may prompt agencies to reevaluate activation criteria and internal decision-making to avoid triggering criminal liability for callers or themselves.
