Unlawful Firearm Possession in California: What You Need to Know in 2025 — And How Perlman & Cohen Can Help

Last Modified: May 15, 2025

California has some of the strictest firearm regulations in the United States, and violations of these laws, especially in Los Angeles, can result in severe criminal charges, mandatory sentencing enhancements, and long-term consequences. Whether you're a first-time offender or have prior convictions, being arrested for unlawful possession of a firearm is not a matter to take lightly.

At Perlman & Cohen, we understand the nuances of California’s weapons laws and how law enforcement aggressively prosecutes gun-related offenses. In this guide, we break down the core laws surrounding unlawful firearm possession, common legal pitfalls, and how our experienced defense team can help protect your rights, your freedom, and your future.

What Is Considered Unlawful Possession of a Firearm in California?

Under California Penal Code § 29800, it is illegal for certain individuals to own, possess, purchase, or receive a firearm. The law applies broadly and includes not only traditional handguns but also rifles, shotguns, and other firearms.

You may be charged with unlawful possession if you fall into any of the following categories:

  • You are a convicted felon
  • You have been convicted of certain violent misdemeanors
  • You are addicted to narcotics
  • You are subject to a domestic violence restraining order
  • You are under 18 years old
  • You are on probation or parole and prohibited from owning a firearm
  • You are a person prohibited under federal law, including certain non-citizens

Possession doesn’t always mean ownership. Courts may also prosecute based on constructive possession—for example, if a gun is found in your home or vehicle and prosecutors believe you had control over it.

Types of Firearm Possession Charges in California

California recognizes several types of illegal firearm possession. Some of the most common charges include:

1. Felon in Possession of a Firearm (PC § 29800)

This is one of the most serious firearm possession charges. If you have a prior felony conviction or certain violent misdemeanor convictions and are found with a firearm, you face a felony charge punishable by up to 3 years in state prison.

2. Carrying a Concealed Firearm Without a Permit (PC § 25400)

Even if you are otherwise eligible to possess a firearm, carrying it concealed in your vehicle or on your person without a valid concealed carry permit is a crime. This can be charged as a misdemeanor or felony depending on the circumstances.

3. Possession of an Unregistered or Assault Weapon (PC § 30600)

California bans the possession of specific firearms considered “assault weapons” and requires registration of all firearms. Possessing an unregistered or prohibited weapon can lead to felony charges.

4. Possession of a Loaded Firearm in Public (PC § 25850)

Carrying a loaded gun in a public place is generally prohibited unless you are licensed. This charge often accompanies other offenses such as traffic stops or altercations.

5. Possession of a Firearm by a Narcotic Addict (PC § 29800(a)(1))

Even without a felony conviction, individuals identified as narcotic addicts by the court may be prohibited from possessing firearms.

Penalties for Unlawful Firearm Possession in California

The penalties for firearm possession crimes vary depending on the statute under which you're charged and your criminal history. However, they generally include:

  • Misdemeanor charges: Up to 1 year in county jail and/or a fine of up to $1,000
  • Felony charges: 16 months to 3 years in state prison and fines up to $10,000
  • Sentencing enhancements: Extra time if a gun was used in the commission of another crime (Penal Code § 12022)

Additionally, a conviction may lead to:

  • Loss of firearm rights
  • Loss of immigration benefits (for non-citizens)
  • Increased penalties for future offenses
  • Difficulty obtaining employment, licensing, or housing

Common Situations That Lead to Charges

Our clients are often charged with unlawful firearm possession under circumstances they never expected. Some of the most frequent scenarios include:

  • Routine traffic stops where a weapon is discovered in the glove box or under a seat
  • Searches during a probation or parole check
  • Domestic disputes that uncover a prohibited weapon in the home
  • Self-defense situations where a firearm is discharged without proper permits
  • Returning to California from another state with legally purchased firearms not registered under CA law

Even if you did not intend to break the law, you can still face criminal charges if law enforcement believes the firearm was under your control and you are a prohibited person.

What About Federal Firearm Laws?

In some cases, federal law may overlap with California’s state statutes—especially if the firearm crossed state lines, was used in a federal crime, or the accused is prohibited under federal law (e.g., due to immigration status, dishonorable military discharge, or restraining orders).

Under 18 U.S. Code § 922(g), possessing a firearm as a prohibited person is a federal felony punishable by up to 10 years in federal prison.

At Perlman & Cohen Los Angeles Criminal Lawyers, our attorneys are well-versed in state court procedures. We are prepared to defend our clients in either venue or coordinate between jurisdictions when federal charges are possible.

How We Defend Firearm Possession Charges at Perlman & Cohen

Our team begins each case with a detailed review of the facts, the arrest procedure, and the client’s criminal history. We approach firearm cases with the same level of intensity as serious felonies because of how significantly a conviction can impact your life.

Common Legal Defenses Include:

  • Unlawful search and seizure: If the firearm was found during an illegal search, we file motions to suppress the evidence.
  • Lack of knowledge: You did not know the firearm was present (common in shared vehicles or homes).
  • No possession: The weapon did not belong to you and was not under your control.
  • False accusations: The firearm was planted or misattributed by another person.
  • Probation conditions misunderstood: You were unaware that you were barred from possessing a firearm.

We also explore mitigating factors, such as lack of criminal history, family responsibilities, or past trauma and negotiate with prosecutors for alternatives like diversion, reduced charges, or probation.

Why You Need an Attorney — Even If You Think It’s a Minor Offense

Some firearm possession cases are charged as misdemeanors, but don’t let that fool you—these charges can have outsized effects on your life. A single conviction could lead to immigration issues, firearm bans, professional licensing problems, and increased penalties if you’re ever charged with another crime.

It’s critical to act quickly and get a defense team involved before charges are filed. Early intervention often gives us the best opportunity to negotiate, challenge the evidence, or keep the case out of court entirely.
