I passed an NICS check for a gun purchase in another state. Does that mean I'm not a prohibited person in California?
Federal Prohibited Categories
18 U.S.C. Section 922(g)[1] establishes nine categories of prohibited persons: felons, fugitives, unlawful users of controlled substances, persons adjudicated as mental defectives or committed to mental institutions, illegal aliens, persons dishonorably discharged from the military, persons who have renounced U.S. citizenship, persons subject to qualifying domestic violence restraining orders, and persons convicted of misdemeanor crimes of domestic violence.
Where California Goes Further
California Penal Code Sections 29800-29905[2] add numerous categories and expand existing ones. The most significant areas of divergence include:
Mental Health Holds (Welfare and Institutions Code Section 5150): Federal law prohibits firearms only for persons "adjudicated as a mental defective" or "committed to a mental institution," both of which require a judicial or administrative proceeding. California goes much further. A 72-hour involuntary psychiatric hold under WIC Section 5150[3] triggers a 5-year firearms prohibition under WIC Section 8103. This hold is initiated by a peace officer or mental health professional, not a judge. The person need never be formally committed or adjudicated. A 14-day intensive treatment certification (5250) or a 30-day post-certification (5300) triggers a lifetime prohibition unless the person petitions for and obtains relief.
Misdemeanor Convictions: Federal law prohibits firearms only for persons convicted of "misdemeanor crimes of domestic violence" as defined in 18 U.S.C. Section 921(a)(33). California prohibits firearms for a much broader list of misdemeanor convictions under Penal Code Section 29805, including assault (PC 240/245), battery (PC 242/243), stalking (PC 646.9), criminal threats (PC 422), and approximately 40 other specified misdemeanors. The prohibition lasts 10 years from the date of conviction.
Restraining Orders: Federal law covers only domestic violence restraining orders that meet specific criteria (issued after hearing, prohibits harassment/stalking/threatening, and the respondent must be an intimate partner or parent of a child). California's prohibition under Penal Code Section 29825 covers a broader range of protective orders, including civil harassment restraining orders (CCP Section 527.6), workplace violence restraining orders (CCP Section 527.8), elder abuse restraining orders (WIC Section 15657.03), and gun violence restraining orders (PC 18100-18205). Many of these do not require the respondent to be an intimate partner or family member.
Juvenile Offenses: Federal law generally does not prohibit firearms based on juvenile adjudications (because they are not "convictions"). California Penal Code Section 29820 prohibits firearms possession until age 30 for juveniles adjudicated for offenses listed in WIC Section 707(b), which includes serious and violent offenses such as murder, robbery, arson, and certain sexual offenses. This means a person adjudicated at age 15 remains prohibited for 15 years, despite having no adult criminal record.
Drug and Alcohol Offenses: Beyond the federal prohibition on unlawful users of controlled substances, California Penal Code Section 29800(a)(2) prohibits firearms for persons addicted to narcotics. Penal Code Section 29805 includes conviction for brandishing a firearm while intoxicated (PC 417.8) in the 10-year prohibition list. DUI convictions alone do not trigger a firearms prohibition under either state or federal law.
Practical Impact
California runs its own background check system (the Bureau of Firearms' DROS process) in addition to the federal NICS check. The DROS system queries state databases including mental health records (MHRS), restraining order databases, and California criminal history that may not appear in NICS. A person who passes NICS in another state may fail a DROS check in California. Conversely, a person prohibited under California law who attempts to purchase in another state may pass NICS because the California-specific prohibiting event was never reported to the federal system.
Bottom Line
Settled: California's prohibited person categories are broader than federal law in every major area. A person cleared under federal NICS may be prohibited under California law. Section 5150 holds create state-level prohibitions without any judicial finding of mental deficiency.
Unsettled: Whether California's broader prohibitions (particularly the 5150-based prohibition and the 10-year misdemeanor prohibition) survive Second Amendment scrutiny under Bruen's historical-analogue framework. The Supreme Court's decision in United States v. Rahimi (2024), which upheld the federal domestic violence restraining order prohibition, may provide guidance but did not address the full scope of California's expanded categories.
Do: If you have any history of mental health treatment, misdemeanor convictions, restraining orders, or juvenile adjudications in California, consult an attorney before attempting to purchase or possess firearms. Do not assume that passing a NICS check in another state means you are eligible in California.
