California has one of the broadest “prohibited persons” frameworks in the country — a long list of people who cannot legally own, possess, or control a firearm, even one purchased legally years before the prohibition attached. The most common charge is felon in possession of a firearm under Penal Code § 29800, which carries a lifetime ban. Other categories — certain misdemeanor convictions under PC § 29805, mental health holds under Welfare and Institutions Code § 8100 and § 8103, domestic violence restraining orders under PC § 29825, and federal prohibitions under 18 U.S.C. § 922(g) — add years or lifetimes of additional restriction. A conviction under any of these provisions carries serious consequences, including state prison, federal prison, and the permanent loss of firearm rights. As a Murrieta felon in possession attorney handling cases at the Southwest Justice Center, Nic Cocis has defended PC § 29800 and related prohibited persons cases across Southwest Riverside County for over 25 years.
If you or someone in your family is facing prohibited persons firearm charges in Murrieta, Temecula, Menifee, Lake Elsinore, Wildomar, Winchester, Canyon Lake, or French Valley, this page covers what you need to know: who is actually prohibited under California and federal law (and who is not, despite common misconceptions), what counts as “possession” of a firearm, the prison and jail exposure, how state and federal prosecution overlap, and the defenses that actually succeed in these cases.
Who Cannot Legally Possess a Firearm in California?
California has multiple categories of “prohibited persons” — a legal term that means a person banned from owning, possessing, or having a firearm under their control. The categories overlap, and a single individual can fall under several at once.
Convicted felons (PC § 29800). Anyone convicted of any felony — California or out-of-state — is barred from possessing a firearm for life. The ban applies regardless of how old the conviction is, whether it was for a violent or non-violent offense, or whether the person served any custody time.
People with specified misdemeanor convictions (PC § 29805). California maintains a list of misdemeanor convictions that trigger a 10-year firearm ban. The list is much longer than most people realize, and includes:
- Domestic violence misdemeanors (PC § 273.5 corporal injury, PC § 243(e)(1) domestic battery)
- Assault and battery convictions (PC § 240, PC § 242, PC § 245 misdemeanor versions)
- Brandishing a firearm (PC § 417)
- Criminal threats (PC § 422 misdemeanor)
- Stalking (PC § 646.9 misdemeanor)
- Certain narcotics convictions
- A range of other listed offenses
The 10-year clock runs from the date of conviction, not the date of arrest or the date of any custody period. For more on how related domestic violence convictions interact with this framework, see the Domestic Violence practice area.
Violent offenders (PC § 29900). A more restrictive lifetime ban applies to anyone convicted of certain enumerated violent felonies. The PC § 29900 list overlaps with PC § 29800 but is more severe in its consequences for any subsequent possession charge.
People with mental health holds and adjudications (WIC § 8100 and § 8103). California imposes firearm prohibitions based on certain mental health events:
- A 72-hour psychiatric hold under WIC § 5150 triggers a 5-year ban
- A subsequent 5150 hold within the 5-year window extends the ban
- Specific mental health adjudications (judicial findings of incompetence, certain civil commitments) trigger a lifetime ban under WIC § 8103
People subject to domestic violence restraining orders (PC § 29825 and federal law). While a domestic violence restraining order is in effect, the restrained person cannot legally possess a firearm. This is true under both California law and federal law (18 U.S.C. § 922(g)(8)).
People who are not U.S. citizens — with important limits. This is one of the most commonly misunderstood categories. Federal law (18 U.S.C. § 922(g)(5)) prohibits firearm possession by aliens who are in the United States illegally, and by most aliens admitted on nonimmigrant visas. Lawful permanent residents — green card holders — can legally own firearms in California and under federal law. A blanket statement that “non-U.S. citizens cannot own firearms” is wrong, and it has misled some legal residents into believing they have no defense to a possession charge when in fact they may have a strong one.
Federal prohibited persons categories also include fugitives from justice, persons under indictment for any crime punishable by more than 1 year, people who use controlled substances, dishonorably discharged military veterans, and people who have renounced U.S. citizenship. Federal charges sometimes follow California arrests when the case fits one of these categories.
What Counts as “Possession” Under California Firearm Law?
Possession in California firearm cases is broader than most people expect, and the legal definition is one of the most contested elements in PC § 29800 cases.
Actual possession is straightforward — the firearm is physically on the person, in their hand, in their pocket, or in their immediate physical control.
Constructive possession is broader and harder to defend. The prosecution can prove possession by showing that the defendant had the right to control the firearm, even without holding it. A firearm in the trunk of the defendant’s car. A firearm in a bedroom closet in the defendant’s home. A firearm in a storage unit rented in the defendant’s name. All of these can support a possession charge under California law, even when the defendant never touched the gun.
Joint possession can apply when multiple people had access to the firearm — for example, a firearm in a shared apartment, in a vehicle with multiple occupants, or in a workplace. The prosecution must still prove that the specific defendant exercised control over the weapon, not just that the weapon was present in a shared space.
Momentary or transitory possession is a recognized defense in narrow circumstances — for example, taking a firearm from another person to render it safe, or briefly handling a firearm during a domestic incident with no intent to control it. The defense is narrow but real, and it is one of the most carefully developed defenses in prohibited persons cases.
The possession analysis is also where Fourth Amendment search and seizure challenges live. Many PC § 29800 cases originate from vehicle searches, home searches following an unrelated arrest, or consent-based searches where the consent itself is challengeable. Suppression of the firearm itself often resolves the case.
What Are the Penalties for Felon in Possession?
PC § 29800 is a wobbler — a charge that prosecutors can file as either a misdemeanor or a felony, depending on the facts of the case and the defendant’s prior record.
Misdemeanor version. Up to 1 year in county jail. Available in some circumstances, especially when the underlying felony was non-violent, the firearm was not used or brandished, and the defendant has no other criminal history beyond the predicate conviction.
Felony version. 16 months, 2 years, or 3 years in state prison under California’s determinate sentencing law. Probation is sometimes available — meaning the defendant serves the sentence on probation with conditions (typically including county jail time as a condition) rather than going directly to state prison. Probation availability depends on the specifics of the case and the prior record.
PC § 29900 felony (violent offender) carries the same nominal sentencing range — 16 months, 2 years, or 3 years — but probation is far more restricted, and the violent-offender designation can affect future sentencing in any other case.
Base fines run up to $1,000 for the misdemeanor version and up to $10,000 for the felony version, before penalty assessments (which often multiply the actual amount paid).
What Are the Penalties for Possession After a Misdemeanor Conviction?
PC § 29805 — the 10-year misdemeanor ban — is itself prosecuted as a misdemeanor when violated. Maximum exposure is up to 1 year in county jail. Probation is typically available, but the conviction itself can extend or restart the firearm prohibition window.
The PC § 29805 conviction also has collateral consequences worth understanding. A new firearm possession conviction during the 10-year ban can be used to argue at sentencing in any future case that the defendant has shown unwillingness to comply with firearm restrictions — a factor that may increase exposure on unrelated charges.
For people whose 10-year ban arose from a domestic violence misdemeanor specifically, federal law (18 U.S.C. § 922(g)(9)) imposes a lifetime ban that runs parallel to the California 10-year ban. Even after California’s 10-year window expires, the federal prohibition continues for life. This is the single most consequential interaction between state and federal firearm law for most defendants in this category.
How Does Federal Law Interact With California Law on Firearm Possession?
Federal prohibited persons law under 18 U.S.C. § 922(g) operates in parallel with California’s framework. When a defendant falls into both state and federal prohibited categories — which is common — the prosecution has a choice of which sovereign to charge under.
Federal charges are typically reserved for cases involving multiple priors (especially under the Armed Career Criminal Act, where three prior violent felony or serious drug convictions can trigger a 15-year mandatory minimum federal sentence), interstate movement of firearms, drug trafficking connections, or other factors that draw federal attention. Federal sentencing exposure is dramatically higher than state: up to 10 years for a basic § 922(g) violation, or up to 15 years with the ACCA enhancement (the Armed Career Criminal Act — federal law that imposes a mandatory minimum 15-year sentence for defendants with three qualifying prior convictions).
When a case is potentially eligible for federal filing, defense work in the state case may shift focus toward preventing the federal referral — by negotiating pleas that don’t establish certain federal predicate facts, or by resolving the case before federal involvement triggers. For more on federal cases generally, see the Federal Crimes practice area.
What Happens When a Restraining Order Is Involved?
A domestic violence restraining order or a permanent protective order with certain findings triggers a firearm prohibition for the duration of the order. California’s parallel statute is PC § 29825; the federal statute is 18 U.S.C. § 922(g)(8).
The federal version — sometimes called the Lautenberg Amendment framework, after the federal law that established it — requires the restrained person to surrender all firearms and ammunition during the order’s effective period. Violation can be charged federally even when the underlying restraining order is purely a state-court order.
The knowledge requirement matters here. Federal prosecution under § 922(g)(8) requires proof that the defendant knew of the restraining order, knew of the firearm prohibition, and knew the firearm was a firearm. Defendants who were never properly served with the protective order, who were not advised at the hearing about the firearm prohibition, or who reasonably believed the order had expired may have viable defenses.
A second issue that frequently arises: even after the restraining order expires, federal law may continue to prohibit possession if the order’s findings established a domestic relationship — triggering the parallel federal misdemeanor domestic violence prohibition under § 922(g)(9), which is lifetime. This is one of the most frequent traps in firearm cases, and a domestic violence misdemeanor plea negotiated without attention to firearm consequences can create lifetime federal exposure that the defendant never anticipated.
What About Mental Health Holds and Adjudications?
California’s mental health firearm prohibition framework lives in the Welfare and Institutions Code, not the Penal Code. The basic structure:
WIC § 5150 — 72-hour psychiatric hold. A 5150 hold for danger to self, danger to others, or grave disability automatically triggers a 5-year firearm ban under WIC § 8100. The ban runs from the date of the hold. A second 5150 hold within the five-year window can extend or restart the ban.
WIC § 8103 — mental health adjudications. Certain mental health-related judicial findings — including incompetence findings, conservatorship determinations, and not-guilty-by-reason-of-insanity verdicts — trigger a lifetime firearm ban. Restoration of rights in these cases requires a specific petition process and a judicial finding that the prohibition is no longer warranted.
The mental health prohibitions are sometimes overlooked when a defendant rebuilds their life after a crisis and assumes their firearm rights returned automatically. They generally do not. Even after a 5-year automatic restoration window closes, defendants in this category should verify their current status before purchasing or possessing a firearm.
How a Felon in Possession Case Can Be Defended
PC § 29800 and related cases have more viable defenses than many felony charges, partly because the prosecution must prove multiple elements that are genuinely contestable in real cases.
Lack of possession. The most frequent defense. Where the firearm was found in a shared space (vehicle, residence, storage unit), the prosecution must prove the specific defendant exercised dominion and control over the weapon. Other people had access. The defendant may not have known the firearm was there. The defendant may have known but did not control it. All of these can defeat the possession element.
No knowledge of the firearm’s presence. Knowledge that the object was a firearm and that it was within the defendant’s control is required. A defendant who was a passenger in a vehicle and did not know a gun was under the seat may have a strong defense.
Challenges to the predicate conviction. PC § 29800 requires a valid felony conviction. In some cases, the predicate can be challenged: was the prior actually a felony or a misdemeanor wobbler that was reduced under PC § 17(b)? Was the conviction set aside? Was the conviction in another state, and does it qualify as a felony under California’s specific definitions? Each of these can eliminate the prohibition.
Status restoration before the alleged possession. A felony conviction that was reduced to a misdemeanor under PC § 17(b) and then dismissed under PC § 1203.4 may not always remove the lifetime federal prohibition (a complicated area of law), but it can in some cases support the defense to a state PC § 29800 charge. For more on expungement options, see the Expungement practice area. For the related concealed carry statute, see the firm’s PC § 25400 framework as part of the broader Firearm Offenses practice area.
Momentary or transitory possession. Where the defendant briefly handled a firearm to render it safe, to remove it from a domestic incident, or in another circumstance with no intent to exercise ongoing control, the defense is recognized in California law. The defense is narrow but real.
Antique firearm exception. Certain antique firearms (generally manufactured before 1899) are excluded from the definition of “firearm” under federal and California law. Where the alleged weapon falls within the antique exception, no possession crime has been committed.
Fourth Amendment suppression. Where the firearm was discovered through a search that lacked probable cause, exceeded the scope of consent, or violated other Fourth Amendment requirements, the firearm itself can be suppressed. Suppression of the firearm typically eliminates the prosecution’s case.
Knowledge of prohibited status — a defense that usually does not work. California courts have generally held that ignorance of one’s own prohibited person status is NOT a defense to PC § 29800. A defendant who believed a prior felony had been “cleared” by completing probation, who did not know an old conviction made them a prohibited person, or who assumed the 10-year misdemeanor window had expired generally cannot raise that lack of knowledge as a defense. (Knowledge of the firearm itself remains an element — see above — but knowledge that the law prohibited possession is a separate question, and the answer in most cases is unfavorable to the defense.) This is an important point because the lay framing of “I didn’t know I couldn’t have a gun” is rarely a winning defense, even when it is true.
For cases involving force used with the firearm — assault, brandishing, robbery, or related charges — the PC § 29800 count typically appears alongside other charges that need their own defense framework. For the related felony assault framework, see the firm’s Violent Crimes practice area.
Can Firearm Rights Be Restored After a Felon in Possession Conviction?
California’s options for restoring firearm rights after a felony conviction are limited and frequently misunderstood.
Expungement under PC § 1203.4 does NOT restore firearm rights for felony convictions. This is the most common misconception. PC § 1203.4 relief seals the conviction from most background checks and allows the defendant to truthfully state they have not been convicted in many contexts — but it does not lift the PC § 29800 firearm prohibition. A defendant whose felony was “expunged” still cannot legally possess a firearm in California.
Reduction to misdemeanor under PC § 17(b), followed by PC § 1203.4 dismissal, may restore firearm rights under California law in some cases. This is a more involved process, available only for wobbler offenses where the court has discretion to reduce the felony, and it requires careful sequencing.
Certificate of Rehabilitation is a state-level relief mechanism for certain felonies. A successful petition leads to a recommendation to the Governor for a pardon. The process is multi-year and discretionary.
Governor’s pardon is the most complete state-level restoration. It is rarely granted and typically requires a Certificate of Rehabilitation as a prerequisite.
Federal relief for federal firearm prohibitions is theoretically available under 18 U.S.C. § 925(c), but Congress has defunded the relief program for individuals since 1992, making federal relief functionally unavailable for most defendants.
The practical implication for defense strategy: avoiding the prohibited person conviction in the first place — by reducing a felony wobbler to a misdemeanor, by accepting a non-§ 29800 plea, or by avoiding a domestic violence misdemeanor plea that triggers the federal lifetime ban — is almost always more achievable than restoring rights after the fact.
The First Decisions That Shape a Prohibited Persons Case
A PC § 29800 case in Murrieta, Temecula, or Menifee is decided in three windows that close quickly.
The window before charges are filed. Before the District Attorney’s Southwest Office files the formal complaint, the case file consists of the police report, the search warrant or other search documentation, the firearm itself with any forensic evidence, and any statements the defendant made. Pre-filing work by a defense attorney — documenting Fourth Amendment problems with the search, demonstrating possession ambiguity in a shared space, or establishing the predicate conviction’s eligibility for PC § 17(b) reduction — can produce favorable outcomes: filing as a misdemeanor rather than a felony, declining to file at all, or filing without related enhancements.
The preliminary hearing window. For felony filings, the preliminary hearing is the defense’s first opportunity to challenge the prosecution’s evidence on the record. Cross-examination of the searching officers, the firearms examiner, and any witness to possession develops the trial record. Successful motions after the preliminary hearing can dismiss the case or reduce charges.
The disposition window. Plea negotiations focus on avoiding the felony where possible (with attention to the lifetime federal ban that attaches to certain pleas), avoiding triggering parallel federal jurisdiction, and planning for any rights restoration that may become possible later.
Why a Murrieta Felon in Possession Attorney Matters Early in a PC § 29800 Case
A PC § 29800 case is not a routine criminal case. Base exposure includes state prison when filed as a felony. Federal exposure runs to 10 years on its own, or 15 years with the Armed Career Criminal Act enhancement. And the rights consequences are essentially permanent — California’s restoration paths are narrow, federal restoration is functionally unavailable, and a conviction here typically means the loss of firearm rights for life.
The decisions that shape the outcome happen in days and weeks, not months:
Within days of arrest. The search that produced the firearm must be analyzed for Fourth Amendment problems before evidence is processed and before the defendant’s options narrow. Witnesses who can support a defense to possession in shared spaces (roommates, co-occupants of a vehicle, anyone with access to the location) must be identified and interviewed before memories fade.
Before the felony complaint is filed. Pre-filing work with the District Attorney’s office can shift the charging tier and prevent federal referral. After the complaint is filed, the case has a docket number, an assigned deputy DA, and institutional momentum that is harder to redirect.
Before any plea. A plea here has consequences that extend far beyond the immediate sentence — the firearm rights consequences, the impact on related state and federal restrictions, and the strategic effect on any future criminal case. A guilty plea entered without attention to the parallel federal framework can create lifetime federal exposure the defendant never anticipated. A felony plea, even with probation, eliminates virtually all paths to firearm rights restoration. Understanding which plea options are available — and which are achievable through negotiation — is critical before any disposition is finalized.
Throughout the case. Investigation of possession ambiguity in shared spaces, challenges to the predicate conviction, suppression motions on the search, and negotiation of charging tier all require sustained defense work that cannot be done in a single hearing.
Anyone arrested for PC § 29800, PC § 29805, or any related prohibited persons charge in Southwest Riverside County — Murrieta, Temecula, Menifee, Lake Elsinore, Wildomar, Winchester, Canyon Lake, or French Valley — should preserve every document and message related to the incident, identify and contact any potential witnesses to possession, and contact a Murrieta felon in possession attorney before any plea is entered.
