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 person taken into custody under WIC Section 5150[3] because they are a danger to themselves or others, assessed, and admitted to a designated facility for that reason is subject to a 5-year firearms prohibition after release under WIC Section 8103(f). If they had another qualifying admission within the preceding year, the firearm prohibition is for life. Court relief is available under that section. 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 certification for intensive treatment under WIC Section 5250 creates a five-year California prohibition under WIC Section 8103(g), subject to court relief and any other applicable prohibition. A qualifying formal commitment to a mental institution also triggers a separate federal prohibition under 18 U.S.C. Section 922(g)(4).
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 court orders issued after a hearing with actual notice and an opportunity to participate that restrain harassment, stalking, or threats against an intimate partner or the child of that partner or the respondent, or other conduct that would place an intimate partner in reasonable fear of bodily injury to the partner or child. The order must also include a credible-threat finding or explicitly prohibit the use, attempted use, or threatened use of physical force against the partner or child that would reasonably be expected to cause bodily injury. California's prohibition under Penal Code Section 29825 covers protective orders including civil harassment restraining orders (CCP Section 527.6), workplace violence restraining orders (CCP Section 527.8), and elder abuse restraining orders (WIC Section 15657.03). Gun violence restraining orders prohibit firearm possession under the separate provisions of 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 a misdemeanor conviction for drawing or exhibiting a firearm in a rude, angry, or threatening manner under PC 417 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. California DOJ examines its own records and authorized State Hospitals records to determine eligibility under state and federal law, and participates in NICS. A person who passes NICS in another state may fail a DROS check in California. For a California transfer, DOJ must notify the dealer if it determines that the purchaser is prohibited under state or federal law.
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.
