A minor in possession of a firearm in California is committing a crime under Penal Code 29610, which bars anyone under 18 from possessing any firearm, handgun, rifle, or shotgun.1California Legislative Information. California Penal Code 29610 A separate statute, Penal Code 29650, makes it equally illegal for a minor to possess live ammunition.2California Legislative Information. California Penal Code 29650 Since July 2023, the prohibition has covered every category of firearm, not just handguns. The weapon does not have to be loaded, and the minor’s intent does not matter. Possession alone is the offense.
Penalties for a Minor Caught With a Firearm
Penal Code 29700 controls the sentencing. The charge depends on two things: the type of firearm and the minor’s record. If the firearm was a handgun, or if the minor has a prior adjudication for firearm or ammunition possession or certain other qualifying offenses, the case is a wobbler. Prosecutors can file it as either a misdemeanor or a felony. Any other violation, such as a first-time offense involving a rifle or shotgun, is a misdemeanor only.3California Legislative Information. California Penal Code 29700
That distinction is not a technicality. A felony-level juvenile adjudication carries harsher long-term effects on firearm rights and record sealing, both covered further down. A minor found with a handgun sits in a very different legal position than one found with a hunting rifle.
Firearms Near Schools
Bringing a firearm onto the grounds of any K-12 school, or within 1,000 feet of one, triggers a much more serious charge under Penal Code 626.9, California’s Gun-Free School Zone Act.4California Legislative Information. California Penal Code 626.9 Minors charged under this statute face the same underlying offense in juvenile court, though the sentence takes shape within the juvenile framework. Any firearm case involving a school zone dramatically increases the exposure.
How the Juvenile Court System Handles the Case
Minors between 12 and 17 who violate California criminal law fall under juvenile court jurisdiction, not the adult system.5California Legislative Information. California Welfare and Institutions Code 602 Juvenile court is oriented toward rehabilitation, but the consequences are real.
For less serious cases, the court can place a minor on probation for up to six months without declaring wardship.6California Legislative Information. California Welfare and Institutions Code 725 If the minor violates probation, or the offense is more serious to begin with, the court can declare the minor a ward. Wardship brings stricter supervision, mandatory counseling, community service, curfews, and other conditions tailored to the case.
Detention in a juvenile facility is reserved for the most serious situations. A prior delinquency history, gang involvement, or connection to other criminal conduct all push the case in that direction. Courts treat confinement as a last resort.
When a Minor Can Legally Possess a Firearm
California carves out narrow exceptions under Penal Code 29615.7California Legislative Information. California Penal Code 29615 Every exception ties possession to a specific lawful activity and requires some form of parental involvement.
- With a parent or legal guardian present, a minor may possess a firearm while actively participating in, or traveling directly to or from, hunting, competitive shooting, ranching, or similar lawful recreational activity.
- With the parent or guardian’s written consent, the same activities can happen under another responsible adult’s supervision.
- A minor at least 16 years old may possess a firearm for these activities with written parental consent, though additional conditions apply for handguns and semiautomatic centerfire rifles.
- With written parental consent, a minor may possess a firearm on land owned or lawfully occupied by the parent or guardian while engaged in lawful recreational activity.
- The exceptions also cover participation in film, television, and theatrical productions involving firearms.
The activity requirement is strict. Simply having parental permission to hold or keep a firearm at home, unconnected to a qualifying activity, does not fall within any of these exceptions.
Defenses to the Charge
Beyond the statutory exceptions, minors charged with possession can raise several defenses. Lack of knowledge is the most common: the minor genuinely did not know the firearm was there. This comes up when a gun turns up in a shared vehicle or a borrowed bag. The defense has to show the minor had no reason to know.
Coercion applies when someone forced or threatened the minor into taking the firearm. Courts look closely at whether the threat was immediate and whether the minor had any real chance to walk away or seek help. Self-defense may apply in narrow situations where possessing the firearm was necessary to prevent imminent serious harm, but this defense faces heavy scrutiny and is difficult to establish.
When Parents and Other Adults Are Liable
California does not limit criminal liability to the minor. Adults who make firearms accessible to children face their own exposure.
Criminal Storage of a Firearm
Penal Code 25100 creates three tiers of liability for storing a firearm where a child can access it.8California Legislative Information. California Penal Code 25100 The severity depends on what happens after access:
- First degree applies when the child accesses the firearm and causes death or great bodily injury. The offense is a wobbler carrying up to three years in state prison or up to one year in county jail.
- Second degree applies when the child accesses the firearm and causes injury short of great bodily injury, or carries it to a public place. It is also a wobbler.
- Third degree applies when the adult negligently stores a firearm where a child is likely to access it, even if nothing happens afterward. It is a misdemeanor.
In every tier, the prosecution must show the adult knew or should have known a child was likely to access the weapon without permission. Owning a firearm in a home with children is not by itself criminal; the question is whether the storage was negligent.
Supplying Firearms to Minors
Penal Code 27505 makes it illegal to sell, loan, or transfer any firearm to a minor, and to sell a handgun to anyone under 21.9California Legislative Information. California Penal Code 27505 Parents and guardians have a narrow exception: they can temporarily loan a firearm to their own child for supervised lawful recreation like hunting or competitive shooting, but only for the duration of that specific activity. Non-parents can loan firearms to minors under tighter restrictions, including written parental consent, a qualifying activity, and a maximum loan period of 10 days for handguns and semiautomatic centerfire rifles.
Long-Term Effect on Firearm Rights
A juvenile adjudication can restrict a minor’s right to own firearms for years after the case closes. Under Penal Code 29820, a juvenile declared a ward of the court for certain offenses cannot own or possess any firearm until turning 30.10California Legislative Information. California Penal Code 29820 Triggering offenses include violent crimes listed in Welfare and Institutions Code 707(b), serious drug trafficking, and firearm-related offenses like carrying a concealed or loaded weapon. Violating the ban is itself a misdemeanor.
The practical effect is significant. A 16-year-old adjudicated for possessing a loaded handgun could be barred from lawfully owning a firearm for the next 14 years, regardless of how their life changes in the meantime. This restriction is one of the most overlooked outcomes of a juvenile firearm case.
Sealing the Juvenile Record
Juvenile records in California are confidential by default, but confidentiality is not the same as erasure. Sealing goes further and, in most cases, treats the record as if it never existed.
Automatic Sealing
When a minor successfully completes probation, the court must dismiss the petition and seal the records automatically. Satisfactory completion means no new felony convictions or misdemeanor convictions involving moral turpitude during probation, and substantial compliance with the court’s orders. Unpaid restitution alone does not block automatic sealing.11California Legislative Information. California Welfare and Institutions Code 786
Automatic sealing is not available if the minor was 14 or older when they committed a serious violent offense listed in Welfare and Institutions Code 707(b), such as murder, robbery, arson, kidnapping, or assault with a firearm.12California Legislative Information. California Welfare and Institutions Code 707 A straight minor-in-possession charge is not on the 707(b) list, so most minors with only a possession offense remain eligible.
Petition-Based Sealing
When automatic sealing does not apply, the minor or the probation officer can petition to seal the record. The petition can be filed five years after juvenile court jurisdiction ends, or anytime after the person turns 18, whichever comes first. The court holds a hearing and considers rehabilitation and whether the person has avoided felony convictions or misdemeanors involving moral turpitude since the case closed. Outstanding fines and fees cannot be used as a reason to deny sealing.13California Legislative Information. California Welfare and Institutions Code 781
Sealing matters because unsealed juvenile records, while confidential, can still surface in background checks for employment, military enlistment, and professional licensing. Once sealed, the person can legally deny the arrest and adjudication ever happened.
