California Penal Code section 29800 makes it a felony for a person previously convicted of any felony to own, purchase, receive, or possess a firearm. It is one of the most aggressively charged firearms statutes in California, with frequent overlap with federal prosecution under 18 U.S.C. § 922(g)(1). This page covers the elements, the common defense angles, the predicate conviction analysis, and the federal exposure.

Elements of PC 29800

To convict, the prosecution must prove: (1) the defendant owned, purchased, received, or possessed a firearm; (2) the defendant knew of the firearm’s presence; AND (3) the defendant had previously been convicted of a felony (or, under PC 29800(a)(1)(B), of certain misdemeanors involving violence). The same statute also lists prohibitions for persons with two or more convictions for assault under PC 245 with a firearm, and for persons addicted to narcotic drugs.

What counts as “possession”

Possession includes actual possession (firearm on the person) and constructive possession (firearm in a place the defendant has dominion and control over, with knowledge of its presence and the ability to access it). Joint occupancy of a vehicle or residence is not enough by itself; the prosecution must prove the specific defendant had knowledge and dominion.

Predicate conviction analysis

The prior conviction underlying a PC 29800 charge is itself often defensible territory.

Post-conviction relief on the predicate. If the underlying felony has been reduced to a misdemeanor under PC 17(b), or if it has been reclassified to a misdemeanor under Prop 47 (PC 1170.18), the conviction may no longer support a PC 29800 charge. Importantly, however, federal law (18 U.S.C. § 922(g)(1)) applies its own analysis and a PC 17(b) reduction does NOT necessarily restore federal firearm rights.

Out-of-state convictions. A felony conviction from another state qualifies as a predicate only if it would have been a felony under California law at the time of the conviction. Challenges to the qualifying nature of out-of-state predicates are viable in some cases.

Juvenile adjudications. A juvenile adjudication is generally NOT a “conviction” for PC 29800 purposes, even for offenses that would be felonies if committed by an adult. Welfare and Institutions Code § 203.

The federal overlay (18 U.S.C. § 922(g)(1))

Felon in possession of a firearm is also a federal crime. Federal prosecutions carry significantly higher exposure: a base 10-year federal maximum, plus mandatory minimums under the Armed Career Criminal Act (ACCA) for defendants with three or more qualifying prior convictions. Federal cases often involve different evidence rules (no PC 17(b) escape valve), different sentencing dynamics, and different plea posture.

Many PC 29800 cases that begin in state court can be referred to federal prosecutors, particularly if there is a federal nexus (interstate firearm, federal informant, federal task force involvement). Defense work in the early stages should always include an assessment of federal exposure.

Common PC 29800 defenses

Lack of knowledge. The prosecution must prove the defendant knew the firearm was present. In a residence-search context, knowing a roommate or family member owned a firearm does not establish the defendant’s possession.

Constructive possession challenges. Multi-occupant residences, shared vehicles, and items found in common areas often produce viable constructive-possession defenses.

Predicate challenges. Post-conviction work on the underlying felony (PC 17(b), Prop 47 reduction, vacatur for ineffective assistance) can sometimes eliminate the predicate and the PC 29800 case along with it.

Fourth Amendment suppression. If the search violated the Fourth Amendment, a PC 1538.5 motion can knock out the firearm evidence.

Antique firearm exception. PC 16520(e) excludes certain antique firearms from the definition of “firearm” for purposes of PC 29800. The exception is narrow and fact-specific.

Sentencing

PC 29800 is a felony punishable by 16 months, 2 years, or 3 years in county jail under PC 1170(h), plus fines and probation conditions. Enhancements apply if the firearm was used in connection with another crime, if it was loaded, or if the defendant has serious prior convictions. Restoration of firearm rights after a PC 29800 conviction is extremely limited under California law and prohibited under federal law without a presidential pardon or successful Section 925(c) petition (currently unfunded by Congress).
