Lending a firearm in California is legal, but only if the loan fits one of the state’s specific exemptions from the licensed-dealer transfer rule. Every firearm loan is treated as a “transfer” by default, and the default requires a dealer, a background check, and a 10-day waiting period.1California Legislative Information. California Penal Code PEN 27545 The exemptions cover common situations like handing a firearm to a family member, letting a guest use it at your home, or taking a friend to the range, but each one has strict conditions you have to meet in full.
The Default Rule and Why It Matters
California law treats a loan the same as a sale: unless an exemption applies, the firearm has to move through a licensed dealer, who runs the borrower through a Department of Justice background check and holds the firearm for a 10-day waiting period before releasing it.1California Legislative Information. California Penal Code PEN 27545 A DROS fee of $31.19 applies, and dealers typically add their own processing charge.2New York Codes, Rules and Regulations. 4001 DROS Fees
If the DOJ finds the borrower is prohibited from possessing firearms, the transfer is blocked and law enforcement may be notified. Skipping the dealer process when it’s required is a crime, and it means no one has confirmed the borrower is legally allowed to have the firearm in the first place.
Loans That Don’t Require a Dealer
Four categories of private loans are exempt from the dealer requirement. You need to satisfy every condition of an exemption for it to apply — missing one condition makes the loan illegal, even if everything else looks fine.
Loans to Close Family Members
You can lend a firearm to a spouse, registered domestic partner, parent, child, sibling, grandparent, or grandchild — including step and adoptive relations — without going through a dealer. The loan cannot exceed 30 days, has to be infrequent rather than a standing arrangement, must be for a lawful purpose, and the borrower needs a valid Firearm Safety Certificate. If the firearm is a handgun, it must be registered to you.3California Legislative Information. California Penal Code 27880
The list is narrow. Aunts, uncles, cousins, in-laws, and friends are not covered by this exemption, no matter how close the relationship.
Loans on Your Own Property
You can hand a firearm to any eligible adult on your residential property, as long as the firearm never leaves the property. The borrower must be at least 18 and not a prohibited person, and any handgun must be registered to you. This is the exemption that covers letting a guest handle or fire your firearm at home.4California Legislative Information. California Penal Code 27881
Supervised Loans for Up to Three Days
If you stay with the borrower the entire time, you can lend a firearm for up to three days without a dealer transfer. Both people must be at least 18, the borrower can’t be a prohibited person, and the loan must be for a lawful purpose. This is what covers taking a friend to a shooting range or on a weekend hunting trip.5California Legislative Information. California Penal Code 27885 The moment you leave the borrower alone with the firearm, this exemption no longer applies.
Loans for Safekeeping
Two separate safekeeping exemptions let someone else hold a firearm for you.
The first covers suicide prevention. You can hand a firearm to another adult to keep it away from someone in your household who is at risk. The borrower has to store it unloaded and secured in a locked container, gun safe, or with a cable lock, and only for as long as reasonably necessary.6California Legislative Information. California Penal Code PEN 27882
The second covers general safekeeping — for example, while you travel or renovate your home. The firearm must stay locked at the borrower’s residence, the loan can’t exceed 120 days, no money can change hands, and both parties have to sign DOJ form BOF-145 acknowledging their obligations.7California Legislative Information. California Penal Code PEN 278838California Department of Justice. Firearm Loan Obligations Acknowledgment Keep the signed form in case questions arise later. The form is only required for this general safekeeping exemption, not for any of the others.
Who Cannot Be a Borrower
Every exemption and every dealer-processed loan requires the borrower to be legally allowed to possess a firearm. California prohibits possession by people convicted of any felony, certain misdemeanors including domestic violence offenses, people subject to restraining orders, and people who have been involuntarily committed for mental health treatment, among other categories.9California Legislative Information. California Penal Code 29800 Lending to someone in a prohibited category exposes you to serious criminal liability whether or not you knew about their status.
Age is a separate limit. No one may lend or transfer any firearm to a person under 18.10California Legislative Information. California Penal Code PEN 27505 Two narrow exceptions apply for minors: a parent or legal guardian can lend a firearm to their own minor child for hunting, competitive shooting, or similar lawful recreation, only for as long as the activity reasonably requires; and a non-parent can lend a semiautomatic centerfire rifle or handgun to a minor for up to 10 days if the minor’s parent or guardian is present or has given written consent.
The Firearm Safety Certificate
Anyone receiving a firearm in California generally needs a valid Firearm Safety Certificate, and that includes borrowers. The one exception maps directly onto the supervised-loan exemption: no FSC is needed if the loan lasts three days or less and the lender stays with the borrower the whole time.11State of California – Department of Justice – Office of the Attorney General. Frequently Asked Questions
Some borrowers are separately exempt from the FSC requirement: active military, law enforcement officers, concealed carry permit holders, and holders of a valid hunting license (for long guns only). Everyone else needs the certificate before taking possession of a loaned firearm for anything longer than a supervised three-day loan.
Storage and Transport Once the Firearm Changes Hands
The borrower has to follow California’s storage and transport rules while the firearm is in their custody, and problems there can come back on the lender through civil liability. In a vehicle, the firearm must be unloaded and locked in the trunk or in a locked container inside the vehicle. A glove compartment or center console does not count as a locked container.12California Legislative Information. California Penal Code 25610
California’s criminal storage law creates liability whenever a firearm is kept where the person in custody of it knows or should know a child or prohibited person is likely to gain access. Using a DOJ-approved gun safe, locked container, or cable lock is the straightforward way to comply.13California Legislative Information. California Penal Code 25100 Several of the loan exemptions build these storage duties directly into the exemption itself, so a storage failure can also invalidate the loan.
Penalties for Getting It Wrong
Skipping the dealer requirement when no exemption applies is a misdemeanor at minimum.14California Legislative Information. California Penal Code 27590 When the firearm involved is a handgun or semiautomatic centerfire rifle, or when the violation involves age or waiting-period rules on those firearms, the offense can be charged as a misdemeanor carrying up to a year in county jail or as a felony, with fines up to $1,000.
Knowingly supplying a firearm to a prohibited person is a felony punishable by two, three, or four years in state prison. The same felony range applies automatically if the person making the illegal transfer has prior firearm convictions, is a prohibited person themselves, or is an active gang member. If a firearm delivered in violation of the age or prohibited-person rules is later used in a felony, an additional consecutive prison term of one to three years applies.
A firearm-offense conviction can also result in a lifetime prohibition on possessing firearms of your own. Civil liability is possible on top of the criminal side if a negligently loaned firearm is used to injure someone.
Borrowers Who Live in Another State
Federal law adds a separate layer when the borrower lives outside California. The Gun Control Act generally prohibits transferring a firearm to someone you know or have reason to believe lives in a different state. The one exception is a temporary loan for lawful sporting purposes, such as lending a rifle to an out-of-state friend for a hunting trip.15Office of the Law Revision Counsel. 18 USC 922 Outside that narrow sporting purpose, an interstate transfer must go through a federally licensed dealer in the borrower’s home state, and California’s rules still apply on top.
Loans That Are Really Purchases
A “loan” structured to hide who the real buyer is creates federal straw purchase liability. When someone buys a firearm from a dealer, they certify on ATF Form 4473 that they are the actual buyer. Using a loan as a way to route the firearm to someone who wanted to avoid a background check exposes both parties to federal prosecution. In Abramski v. United States, the U.S. Supreme Court held that this rule applies even when the intended recipient could legally buy the firearm on their own. The dividing line is whether the lender genuinely retains ownership and intends to get the firearm back.
Matching Your Situation to the Right Rule
- Handing a firearm to someone at your home who won’t leave the property with it: no dealer needed; borrower must be 18+ and not prohibited; handguns must be registered to you.4California Legislative Information. California Penal Code 27881
- Lending to a close family member for up to 30 days: no dealer needed; borrower needs an FSC; handguns must be registered to you.3California Legislative Information. California Penal Code 27880
- Taking a friend shooting and staying together the whole time, up to 3 days: no dealer needed, no FSC needed; both must be 18+.5California Legislative Information. California Penal Code 27885
- Asking someone to hold your firearm for safekeeping, up to 120 days: no dealer needed; sign the BOF-145; store locked at the borrower’s home; no payment.7California Legislative Information. California Penal Code PEN 27883
- Lending to a non-family member who will take it home unsupervised: must go through a licensed dealer with a background check and 10-day waiting period.1California Legislative Information. California Penal Code PEN 27545
When a situation doesn’t cleanly fit any exemption, running the loan through a dealer is the safe choice. The fee and the 10-day wait are small compared to what a misclassified loan can cost.
