To meet California firearm purchase requirements, you must be at least 21, pass a Department of Justice background check through a licensed dealer, hold a valid Firearm Safety Certificate, present the right identification, wait 10 days, and complete a safe handling demonstration before you can take the gun home. The same process applies whether you’re buying from a retail dealer or from another private individual, since private party transfers also have to go through a licensed dealer.
Who Can Legally Buy
You must be 21 or older to purchase any firearm in the state, handgun, rifle, or shotgun. Penal Code 27510 prohibits licensed dealers from selling or giving a firearm to anyone younger, with narrow exceptions for law enforcement and military personnel.1California Legislative Information. California Code Penal Code 27510
Age isn’t the only gate. Penal Code 29800 bars anyone convicted of a felony or addicted to narcotics from possessing a firearm.2California Legislative Information. California Penal Code 29800 Other statutes extend the prohibition to people convicted of certain violent misdemeanors, those under active restraining orders, and people under indictment for crimes punishable by more than a year.3State of California – Department of Justice – Office of the Attorney General. Personal Firearms Eligibility Check Program
Mental health history can also disqualify you. If a court has found you dangerous to others because of a mental disorder, found you not guilty by reason of insanity, determined you incompetent to stand trial, or placed you under a mental health conservatorship, you cannot purchase or possess a firearm.4California Legislative Information. California Welfare and Institutions Code 8103 A history of substance abuse can trigger the same result. Buying or possessing a firearm while prohibited is a felony.
What You Need Before You Walk Into the Dealer
A Firearm Safety Certificate
You can’t start a purchase without a valid Firearm Safety Certificate (FSC). You get one by passing a 30-question written test given by a DOJ Certified Instructor, usually right at the dealer’s counter. You need a score of at least 75%, and the $25 fee covers two attempts. The certificate is good for five years.5State of California – Department of Justice – Office of the Attorney General. Firearm Safety Certificate Program FAQs
The test covers safe handling and storage, how different firearms operate, ammunition basics, prohibited transfers like straw purchases, and key California firearms laws, including the rules on concealed carry and the use of lethal force in self-defense.6State of California – Department of Justice – Office of the Attorney General. Firearm Safety Certificate Study Guide Active and retired law enforcement officers and military personnel with valid credentials are generally exempt.
Identification
Bring a valid California driver license or California ID card. Military ID also works, but only if you present it with permanent duty station orders showing a California posting; the dealer keeps copies of both.7State of California – Department of Justice – Office of the Attorney General. California Firearms Dealer Frequently Asked Questions You do not need a Real ID-compliant card. However, if your license or ID says “Federal Limits Apply” on the front, the dealer must also see proof that you are lawfully present in the United States.
Acceptable supplemental documents include a valid U.S. passport or passport card, a certified U.S. birth certificate, a Certificate of Naturalization, a valid Permanent Resident Card, or a valid foreign passport with an approved immigration visa and I-94.8State of California – Department of Justice – Office of the Attorney General. Identification Requirements for Firearms and Ammunition Eligibility If the name on your “Federal Limits Apply” ID differs from the name on your supplemental document, bring certified documentation of the change too, such as a marriage certificate or court-ordered name change.
A Second Document for Handgun Buyers
If you’re buying a handgun, you need a second document confirming your residential address, and the address has to match either your DROS application or your driver license. A utility bill from the past three months, a residential lease, or a property deed will do. Post office boxes aren’t accepted.7State of California – Department of Justice – Office of the Attorney General. California Firearms Dealer Frequently Asked Questions
The Dealer Record of Sale
The Dealer Record of Sale (DROS) is the electronic form that starts your background check and registers the firearm with the state. Every purchase, and every private party transfer, has to go through DROS at a licensed dealer.
You’ll provide your full legal name, any aliases, date and place of birth, residential address, email, phone number, occupation, and a physical description. You’ll answer yes-or-no questions about disqualifying factors such as felony convictions, mental health adjudications, and restraining orders. The dealer records your right thumbprint on the form. On the firearm side, the dealer enters the make, model, serial number, caliber, barrel length, color, type, and whether it’s new or used. You sign under penalty of perjury.9California Legislative Information. California Code Penal Code 28160
The total DROS fee is $37.19, which includes a $31.19 processing fee plus additional statutory fees.10State of California – Department of Justice – Office of the Attorney General. Firearms Fees For a private party transfer handled through a dealer, add a $10 per-firearm dealer fee on top of the DROS costs.
The 10-Day Waiting Period
Once the DROS is submitted, the mandatory waiting period starts. Penal Code 26815 prohibits a dealer from delivering a firearm within 10 days of the application.11California Legislative Information. California Penal Code 26815 During that window, DOJ runs your information against California criminal records, mental health databases, and federal systems.
Three outcomes are possible. An approval lets the dealer release the firearm after day 10. A denial stops the transfer. An “undetermined” status happens when DOJ cannot confirm your eligibility within 30 days, in which case releasing the firearm is left to the dealer’s discretion.12Legal Information Institute (LII). Delivery of Firearms Following DROS Submission and Suspension If DOJ needs more time to investigate, the review can be extended to 30 days. If you’re denied, DOJ sends a letter within about two weeks explaining the reason and how to dispute it.
The 10 days aren’t quite absolute. If you already own a firearm recorded in California’s Automated Firearms System, hold a valid concealed carry permit, or have a Certificate of Eligibility with a firearm on record, the dealer may release the firearm earlier once DOJ has completed the check and cleared you.
One Firearm Every 30 Days
California limits you to one firearm purchase within any 30-day period. The cap covers all firearms, including completed and unfinished frames and receivers, and applies to both dealer sales and private party transfers.13California Legislative Information. California Penal Code 27535 A second DROS submitted inside that window will be flagged and the dealer cannot proceed.
Exceptions are narrow. Law enforcement agencies and full-time peace officers are exempt, as are licensed Curio and Relic collectors with a valid Certificate of Eligibility buying qualifying firearms.14State of California – Department of Justice – Office of the Attorney General. Firearms Frequently Asked Questions Transfers where the seller must relinquish all firearms under court order, and estate transfers from a deceased person’s representative to an heir, are also exempt.
Which Firearms You Can Actually Buy
Even if you qualify, not every firearm is available for sale in California. Handguns sold at retail must appear on the DOJ Roster of Handguns Certified for Sale, having passed firing, safety, and drop tests under rules in effect since 2001.15California Department of Justice. Handguns Certified for Sale Models whose certification has expired cannot be sold through dealers, though private party transfers, curio and relic handguns, and certain single-action revolvers are exempt from the roster.
California also bans assault weapons, defined by specific make and model as well as by physical features, and prohibits the sale of magazines holding more than 10 rounds.16State of California – Department of Justice – Office of the Attorney General. Assault Weapons Laws – California and Federal Law Check the roster and the assault weapon rules before you commit to a specific model.
Picking Up the Firearm
Once DOJ approves and the 10 days have passed, you return to the dealer to collect your firearm. You have from day 10 through day 30 to complete the pickup. Miss that window and the DROS expires, meaning you’d start over and pay the fees again.
Before the dealer hands the firearm over, you have to perform a safe handling demonstration using that exact firearm. For a semiautomatic pistol, that means safely removing and inserting the magazine, locking the slide back, visually and physically checking the chamber, loading and ejecting a dummy round, and applying the safety and any firearm safety device, all while maintaining muzzle awareness and trigger discipline.17New York Codes, Rules and Regulations. 11 CCR 4258 – Safe Handling Demonstration Steps for Handguns with Alternative Designs
Every firearm must also leave with a California-approved firearm safety device, such as a cable lock listed on the DOJ roster. You can buy one from the dealer, usually for under $10, or show you own a qualifying gun safe by presenting a receipt and signing an affidavit under penalty of perjury.18California Department of Justice. Firearm Safety Devices Frequently Asked Questions The dealer confirms the device is present before releasing the firearm.
Ammunition and New-Resident Rules
Buying ammunition triggers its own background check. Before a licensed vendor can sell you ammunition, DOJ has to run an eligibility check and approve the sale electronically. If your name, date of birth, address, and ID all match an existing record in the Automated Firearms System and you’re not prohibited, the check clears quickly. If you have no AFS record, the sale requires a manual review by a DOJ analyst, which can take several days. The simplest way to build an AFS record is through a prior California dealer purchase; you can also file a Firearm Ownership Report through the California Firearms Application Reporting System (CFARS).19State of California – Department of Justice – Office of the Attorney General. Ammunition Purchase Authorization Program
If you’re moving to California with firearms you already own, you must report them to DOJ within 60 days of becoming a resident. File a New Resident Report of Firearm Ownership (BOF 4010A) with a $19 processing fee and a copy of your California driver license or ID. Supplemental proof of lawful presence is required if your ID says “Federal Limits Apply.”20State of California – Department of Justice – Office of the Attorney General. New Resident Report of Firearm Ownership Reporting a firearm does not legalize it: assault weapons, large-capacity magazines, and off-roster handguns stay prohibited whether you register them or not.
