A minor in possession of a firearm in California is committing a crime under Penal Code 29610, which bans anyone under 18 from having any firearm — handgun, rifle, or shotgun. The case is handled in juvenile court and charged as a misdemeanor, unless the weapon was a handgun or the minor has a qualifying prior, in which case prosecutors can file it as a felony-level wobbler. Consequences can reach well past the courtroom, including a firearm prohibition that lasts until age 30.
What the Law Prohibits
Penal Code 29610 is the controlling statute, and since July 2023 it covers every type of firearm rather than just handguns.1California Legislative Information. California Penal Code 29610 A companion statute, Penal Code 29650, separately bans minors from possessing live ammunition.2California Legislative Information. California Penal Code 29650
The prohibition is strict. It doesn’t matter whether the firearm was loaded, where it was found, or what the minor planned to do with it. Possession alone is the offense.
Misdemeanor or Felony?
Penal Code 29700 sets the penalties, and the type of weapon decides a lot. A first-time offense with a rifle or shotgun is a misdemeanor. If the firearm was a handgun, or if the minor has a prior adjudication for firearm or ammunition possession (or certain other listed offenses), the charge becomes a wobbler, meaning prosecutors can file it as either a misdemeanor or a felony.3California Legislative Information. California Penal Code 29700
That distinction shapes everything that follows. A felony-level juvenile adjudication carries heavier consequences for future firearm rights and makes record sealing harder down the road.
Near a School, the Exposure Jumps
Possessing a firearm on K-12 school grounds, or within 1,000 feet of a school, triggers a separate charge under Penal Code 626.9, California’s Gun-Free School Zone Act.4California Legislative Information. California Penal Code 626.9 For adults, the statute carries two, three, or five years in state prison when the firearm is on school grounds. Minors face the same underlying offense in juvenile court, though sentencing works within the juvenile system’s framework.
What Juvenile Court Can Do
Minors between 12 and 17 fall under juvenile court jurisdiction rather than the adult system.5California Legislative Information. California Welfare and Institutions Code 602 The system is built around rehabilitation, but the consequences are real.
For less serious cases, the court can place the minor on informal probation for up to six months without declaring them a ward of the court.6California Legislative Information. California Welfare and Institutions Code 725 If the minor breaks the probation conditions, or if the offense is more serious to begin with, the court can declare wardship. That brings stricter supervision, mandatory counseling, community service, curfews, and other conditions set to the minor’s situation.
Detention in a juvenile facility is reserved for the most serious cases. Courts weigh prior delinquency, aggravating circumstances like gang involvement, and whether the firearm offense was tied to other criminal conduct. Confinement is treated as a last resort when less restrictive options have failed or the minor presents a clear safety risk.
When a Minor Can Legally Have a Firearm
California carves out specific situations where a minor can legally possess a firearm, all tied to supervised recreational or agricultural activity. Penal Code 29615 is where they live, and the common thread is parental involvement with a lawful purpose.7California Legislative Information. California Penal Code 29615
- With a parent or legal guardian present, while actively engaged in or traveling directly to or from hunting, competitive shooting, ranching, or other lawful firearm-related recreation.
- With another responsible adult, if the parent or guardian has provided written consent.
- For minors 16 and older, with written parental consent, without a supervising adult at all times — though not for handguns or semiautomatic centerfire rifles absent additional conditions.
- On land owned or lawfully occupied by the parent or guardian, with written parental consent, while engaged in lawful recreational activity.
- In connection with film, television, or theatrical productions that use firearms.
Every exception requires the minor to be actively engaged in (or traveling to or from) the qualifying activity. Having general parental permission to “hold” a firearm at home, without a connected lawful activity, doesn’t qualify.
Defenses to the Charge
Beyond the statutory exceptions, several defenses can apply depending on the facts.
Lack of knowledge is the most common. If the minor genuinely didn’t know the firearm was present — a gun stashed in a shared vehicle, or a backpack carried for someone else — the defense works by showing the minor had no reason to know it was there.
Coercion is also recognized. If someone forced or threatened the minor into possessing the firearm, the defense argues there was no realistic choice. Courts look at whether the threat was immediate and whether the minor had any chance to seek help or walk away.
Self-defense may apply in rare situations where possessing the firearm was necessary to prevent imminent serious harm. The defense faces intense scrutiny and is difficult to establish.
The Firearm Ban Until Age 30
This is the consequence most families don’t see coming. Under Penal Code 29820, a juvenile declared a ward of the court for committing certain offenses cannot own or possess any firearm until turning 30.8California Legislative Information. California Penal Code 29820 The 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.
A 16-year-old adjudicated for possessing a loaded handgun can be barred from legally owning a firearm for the next 14 years. The restriction applies regardless of how the person’s life has changed since.
Sealing the Record Afterward
Juvenile records in California are confidential by default, but confidential isn’t invisible. Certain agencies can still access them, and they can surface in background checks for employment, military enlistment, and professional licensing. Sealing destroys the record in a more meaningful way. There are two paths.
Automatic Sealing
If the minor satisfactorily 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 court orders. Unpaid restitution alone won’t block automatic sealing.9California Legislative Information. California Welfare and Institutions Code 786
There’s an exception: automatic sealing is unavailable if the minor was 14 or older and committed a serious violent offense on the Welfare and Institutions Code 707(b) list, which covers crimes like murder, robbery, arson, kidnapping, and assault with a firearm.10California Legislative Information. California Welfare and Institutions Code 707 A straightforward minor-in-possession charge, by itself, is not on that list, so most minors with only a possession offense stay eligible.
Petition-Based Sealing
When automatic sealing doesn’t apply, the minor or the probation officer can petition the court. 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 looks at whether the person has been rehabilitated and avoided felony convictions or misdemeanor convictions involving moral turpitude since the case ended. Outstanding restitution fines and court fees can’t be used as a reason to deny sealing.11California Legislative Information. California Welfare and Institutions Code 781
Once sealed, the records are treated as though they never existed, and the person can legally deny the arrest and adjudication ever happened.
A Note on Adult Liability
The minor isn’t the only one exposed. Adults who negligently store firearms where a child can access them can be charged under Penal Code 25100, with penalties scaled by what the child does with the gun.12California Legislative Information. California Penal Code 25100 Selling, loaning, or transferring a firearm to a minor is separately prohibited under Penal Code 27505, with narrow exceptions for parents loaning a firearm for supervised lawful recreation.13California Legislative Information. California Penal Code 27505 If a minor’s case is being investigated, the adults in the household may face their own charges.
