Felon with a Firearm Lawyers (PC 29800)

A felony conviction from years ago can follow you into places you never expected. When a traffic stop, a search, or even a visit to someone else’s home leads to a PC 29800 charge, the consequences can upend the stable life you’ve worked hard to rebuild.

California’s felon-in-possession law punishes people for owning, purchasing, receiving, or simply having access to a firearm after a prior felony conviction. The charge is a straight felony carrying up to three years in state prison, and prosecutors in Alameda County and throughout the Bay Area treat these cases seriously. But the prosecution’s burden is heavier than most people realize. They must prove not only that you possessed a firearm, but that you knew it was there and that you knew you were legally prohibited from having one.

That gap between what the law requires and what law enforcement assumes is where defense strategy lives. Our team at The Nieves Law Firm Criminal Defense Attorneys has defended hundreds of weapons cases across the Bay Area, and we understand how to challenge every element the prosecution must establish.

What Penal Code 29800 Actually Prohibits

Penal Code section 29800 makes it a felony for any person who has been convicted of a felony to own, purchase, receive, or have in their possession or under their custody or control any firearm.¹ The statute also covers persons convicted of certain specified misdemeanors listed in Penal Code section 29905, persons addicted to narcotics, and persons with two or more brandishing convictions under Penal Code section 417.²

The word “firearm” is defined broadly under Penal Code section 16520 as any device designed to be used as a weapon from which a projectile is expelled through a barrel by the force of an explosion or other form of combustion.³ This covers handguns, rifles, shotguns, and in most circumstances, even antique firearms.

What makes PC 29800 distinct from other possession offenses is the status element. The crime is not about the firearm itself being illegal. It is about who is holding it.

What Prosecutors Must Prove

Under CALCRIM No. 2510, the prosecution must prove every one of the following elements beyond a reasonable doubt to secure a conviction:⁴

You possessed a firearm or had it under your custody or control. Possession does not require physically holding the weapon. Constructive possession, meaning dominion and control over the firearm, is sufficient. If a gun is found in your bedroom closet, in your car’s glove compartment, or in a storage unit you rent, prosecutors will argue you had custody or control even if you never touched it.

You knew you possessed the firearm. This is a genuine knowledge requirement. The prosecution must show you were aware the firearm was present and that the object was in fact a firearm. If someone placed a weapon in your bag without your knowledge, or if a firearm was hidden in a vehicle you borrowed, this element may not be satisfied.

You had previously been convicted of a qualifying felony. The prior conviction must be established through certified court records. The conviction can be from California, another state, the federal system, or a foreign country.⁵

You knew you had been convicted of a qualifying felony. This fourth element, addressed in CALCRIM No. 2511, is often the most underappreciated.⁶ Following legislative changes and California case law, prosecutors cannot simply assume a defendant knew about their prohibited status. This matters in situations where a prior conviction was a wobbler that the defendant believed resolved as a misdemeanor, where the defendant’s record was later modified through Proposition 47 or another post-conviction remedy, or where the defendant genuinely did not understand that a particular conviction carried felony-level consequences.

Constructive Possession and the “Dominion and Control” Standard

One of the most frequently litigated issues in PC 29800 cases is constructive possession. Prosecutors do not need to show you were physically holding a firearm. They only need to show you had the right to control it or the ability to exercise dominion over it.

In practice, this creates a wide net. A firearm found under a mattress in a shared apartment, in the trunk of a car with multiple occupants, or in a garage that several people access can all lead to a PC 29800 charge. But proximity alone is not enough. The prosecution must connect you specifically to the weapon through evidence of dominion and control.

This is where defense teams find real opportunities. When multiple people have access to the location where a firearm was found, the prosecution faces a significant challenge. Without fingerprints, DNA, purchase records, witness testimony, or other evidence specifically tying you to the weapon, the constructive possession theory can fall apart.

Our attorneys routinely challenge constructive possession arguments by investigating who else had access to the location, whether forensic evidence actually links the defendant to the firearm, and whether the prosecution is relying on assumptions rather than proof.

Penalties for PC 29800

Penal Code section 29800 is a straight felony. It cannot be reduced to a misdemeanor.⁷

Under California’s realignment legislation (AB 109), defendants whose prior convictions were not classified as serious or violent felonies may serve their sentence in county jail rather than state prison under Penal Code section 1170(h).⁸ This distinction matters enormously for defendants with older, non-violent felony histories.

Formal felony probation may be available in some cases, particularly where the prior felony was non-violent and significant mitigating circumstances exist. The court will consider the probation department’s report, the nature of the underlying felony, and the circumstances of the current offense.

Sentence Enhancements That Can Stack

PC 29800 charges rarely exist in isolation. Prosecutors frequently add enhancements and companion charges that can dramatically increase exposure.

The gang enhancement under Penal Code section 186.22 is particularly significant in Bay Area cases.⁹ If prosecutors allege the firearm possession was committed for the benefit of, at the direction of, or in association with a criminal street gang, the additional prison time can dwarf the base sentence.

Strike Status

Penal Code section 29800 is not automatically classified as a serious felony under Penal Code section 1192.7(c) or a violent felony under Penal Code section 667.5(c).^{10 11} This means it is not a strike offense on its own.

However, if your prior conviction is a strike, the current PC 29800 sentence will be doubled under the second-strike rule. If you have two or more prior strikes, a PC 29800 conviction could trigger a 25-years-to-life sentence under the third-strike rule. The charge itself may not be a strike, but it can activate strike consequences from your record.

Defense Strategies Our Team Uses

Challenging the Search That Found the Firearm

Fourth Amendment violations are among the most powerful defenses in PC 29800 cases. If law enforcement conducted an unlawful traffic stop, executed a warrantless search without a valid exception, or exceeded the scope of a search warrant, the firearm evidence may be suppressed through a Penal Code section 1538.5 motion.¹²

In our experience, search-and-seizure issues arise frequently in Bay Area firearms cases. Common problems include traffic stops based on pretextual reasons without reasonable suspicion of criminal activity, searches of vehicles or homes without consent, warrant, or exigent circumstances, and probation or parole searches that exceed the specific conditions imposed by the court. Body camera footage has become an invaluable tool for identifying these issues, and our team reviews every available recording.

Lack of Knowledge of Possession

If you did not know the firearm was present, you cannot be convicted under PC 29800. This defense applies in scenarios involving shared living spaces where a roommate or family member owned the weapon, borrowed vehicles where the firearm belonged to the vehicle’s owner, and situations where someone else placed the firearm in your belongings without your knowledge.

Lack of Knowledge of Prohibited Status

The prosecution must prove you knew you had a qualifying felony conviction.¹³ This is not always straightforward. If your prior conviction was a wobbler offense and you believed it was resolved as a misdemeanor, if you went through an expungement process and believed your rights were restored, or if you did not understand that an out-of-state conviction qualified as a felony under California law, this element may be genuinely contested.

Transitory or Momentary Possession

California recognizes a defense where the defendant possessed the firearm only briefly for the purpose of disposing of it or turning it over to authorities. To establish this defense, you must show that your possession was brief and transitory, that your purpose was to dispose of or neutralize the weapon, and that you had no other unlawful purpose. This defense applies in situations where someone discovers a firearm and picks it up to move it to safety, turn it in, or prevent someone else from using it.

The Prior Conviction Does Not Qualify

Not every felony conviction triggers PC 29800 liability permanently. If your prior felony was reclassified as a misdemeanor under Proposition 47, you may no longer be a prohibited person under state law.¹⁴ Similarly, if a wobbler offense was reduced to a misdemeanor under Penal Code section 17(b), or if an out-of-state conviction does not meet California’s definition of a felony, the foundation of the PC 29800 charge may be eliminated entirely.

This is an area where our team’s familiarity with post-conviction relief becomes a significant advantage. We routinely investigate whether a client’s underlying conviction can be reclassified or challenged as a predicate for the current charge.

Insufficient Circumstantial Evidence

When the prosecution’s case rests entirely on circumstantial evidence, the jury must follow CALCRIM No. 224: if two reasonable interpretations of the evidence exist, one pointing to guilt and one to innocence, the jury must adopt the interpretation pointing to innocence.¹⁵ In cases where the firearm was found in a common area, where no forensic evidence links you to the weapon, and where the prosecution’s theory requires stacking inferences, this instruction can be decisive.

Proposition 47 and the Shifting Foundation of PC 29800

One of the most strategically important developments in PC 29800 defense is Proposition 47, the Safe Neighborhoods and Schools Act passed in 2014.¹⁶ Proposition 47 reclassified several non-violent felonies as misdemeanors, including certain drug possession offenses and theft offenses involving amounts under $950.

The significance for felon-in-possession cases is straightforward: if the underlying felony that makes you a prohibited person has been reclassified as a misdemeanor under Proposition 47, you may no longer be a “person convicted of a felony” for purposes of PC 29800. This does not happen automatically. You must petition the court to have the prior conviction redesignated. But once that redesignation is granted, the legal basis for the PC 29800 charge disappears.

Our attorneys investigate every client’s criminal history for Proposition 47 eligibility as a standard part of case evaluation. We have seen cases where clients did not realize their old drug possession conviction could be reduced, and where that single reclassification eliminated the firearm charge entirely.

It is worth noting that expungement under Penal Code section 1203.4 generally does not restore firearm rights.¹⁷ This is one of the most common misunderstandings our clients have. A Proposition 47 reclassification to a misdemeanor is a different remedy with different consequences than an expungement, and understanding the distinction is critical.

Offenses Commonly Charged Alongside PC 29800

Prosecutors frequently stack charges in firearms cases to increase leverage during plea negotiations.

The charge-stacking approach is common in Alameda County. Understanding how these charges interact and which ones carry the most exposure is essential to developing an effective defense and negotiation strategy. Our team evaluates every count individually and identifies which charges are most vulnerable to challenge.

Collateral Consequences Beyond the Sentence

A PC 29800 conviction carries consequences that extend well beyond the prison or jail term.

Permanent firearm prohibition. A conviction adds another felony to your record, reinforcing and extending the lifetime prohibition on firearm possession under both state and federal law.

Employment impact. A new felony conviction will appear on background checks and can disqualify you from positions requiring security clearances, professional licenses, or clean criminal records. For working professionals who have moved past a prior conviction, this can be devastating.

Immigration consequences. For non-citizens, a PC 29800 conviction is a deportable offense under federal immigration law. It may also constitute an aggravated felony depending on the sentence imposed, which would bar most forms of relief from removal. If you are not a U.S. citizen, discussing the immigration implications with your defense attorney before accepting any plea is essential.

Housing. Many landlords and housing programs conduct criminal background checks. A new felony conviction can result in denial of housing applications or termination of existing housing assistance.

Professional licensing. State licensing boards for healthcare, education, finance, and other regulated industries may revoke or deny licenses based on a new felony conviction.

Where Your Case Will Be Heard

Most PC 29800 cases originating in Oakland and the surrounding area are heard at the Rene C. Davidson Courthouse at 1225 Fallon Street in Oakland, which serves as the primary felony courthouse for Alameda County. Cases originating in the southern part of the county may be assigned to the Fremont Hall of Justice or Hayward Hall of Justice.

Alameda County prosecutors handle a high volume of firearms cases and frequently stack companion charges like PC 30305 (ammunition possession) to increase plea bargaining leverage. Our team appears regularly in these courtrooms and understands how local judges and prosecutors approach PC 29800 cases, which informs every strategic decision from the initial motion practice through trial preparation.
