San Diego gun laws stack three layers on top of each other: federal rules, California’s statewide firearms code (one of the strictest in the country), and a set of city ordinances that add their own requirements for home storage, unserialized firearms, and weapons in parks. If you live in or travel through the city with a gun, you have to clear all three.
Buying a Firearm in San Diego
Every purchase runs through a licensed dealer and triggers a 10-day waiting period. The clock starts when the California Department of Justice accepts your Dealer Record of Sale and issues a transaction number, and you cannot take the gun home until ten full 24-hour periods have passed, even if your background check clears in minutes.1State of California – Department of Justice – Office of the Attorney General. Frequently Asked Questions – Dealer
You also need a current Firearm Safety Certificate before the dealer can hand anything over. The FSC comes from passing a written test at a licensed dealer covering safe handling, storage, and California law. Buying or receiving a firearm without one is a misdemeanor, and so is transferring a gun to someone who lacks one.2California Legislative Information. California Code PEN 31615 – Firearm Safety Certificate
Your handgun choices are narrower here than in most states. The California Department of Justice keeps a roster of handguns certified as not unsafe, and a licensed dealer cannot sell you a new handgun that is not on it.3California Legislative Information. California Code PEN 32015 – Roster of Handguns Certified for Sale You are also limited to one firearm, frame, receiver, or precursor part per 30 days.4California Legislative Information. California Code PEN 27535 – Limitation on Firearm Applications Private-party sales get no exception: every transfer in California goes through a licensed dealer and includes a background check, even between people who know each other.
City Rules That Go Beyond California Law
Locked Storage at Home
San Diego Municipal Code Section 53.17 requires every firearm in a residence to be stored in a locked container or disabled with a trigger lock. The exception is a gun you are physically carrying, or one close enough that you could grab and use it as if it were on your person. A separate provision protects owners who report a lost or stolen firearm from prosecution for violating the storage rule for that specific weapon.5City of San Diego. San Diego Municipal Code Chapter 5 Article 3 – Firearms, Dangerous Weapons
Unserialized Firearms (Ghost Guns)
Section 53.18 bans possessing, buying, selling, or transporting any unfinished frame or receiver that does not carry a serial number from a federal firearms manufacturer or the California Department of Justice. The ordinance also bans possessing any completed firearm without a serial number. Narrow exceptions cover antique firearms, guns made before 1968, permanently inoperable weapons, and items that qualify as collector pieces under federal law.6City of San Diego. San Diego Ordinance O-21367 – Prohibition of Non-Serialized Firearms
Guns in City Parks
San Diego Municipal Code Section 63.08 prohibits possessing, carrying, or firing any firearm in a city park or designated open space without specific legal authorization or a city permit. Unloaded carry in a park is an infraction. Loaded carry is a misdemeanor punishable by fines or jail time.7City of San Diego. San Diego Municipal Code Chapter 6 Article 3 – Public Parks, Playgrounds, Beaches
What You Cannot Own
Assault Weapons
California bans an extensive list of firearms as assault weapons. Penal Code 30510 names specific prohibited models, and Penal Code 30515 defines a broader category by feature. A semiautomatic centerfire rifle without a fixed magazine is an assault weapon if it has any one of these: a protruding pistol grip, a thumbhole stock, a folding or telescoping stock, a flash suppressor, a forward pistol grip, or a grenade or flare launcher. A semiautomatic centerfire rifle with a fixed magazine over 10 rounds also qualifies, as does a semiautomatic shotgun with both a folding stock and a protruding pistol grip. Any shotgun with a revolving cylinder is banned outright.8California Legislative Information. California Code PEN 30515 – Assault Weapon Definition Possession is a wobbler: prosecutors can charge it as a misdemeanor carrying up to a year in county jail or a felony carrying up to three years in state prison.
Large-Capacity Magazines
Any magazine that accepts more than 10 rounds is a large-capacity magazine, except .22 caliber tube feeders and tubular magazines in lever-action firearms.9California Legislative Information. California Code PEN 16740 – Large-Capacity Magazine Definition Possession is either an infraction with a fine of up to $100 per magazine or a misdemeanor with up to a year in county jail plus the per-magazine fine. Importing or selling them carries steeper penalties.10California Legislative Information. California Code PEN 32310 – Large-Capacity Magazines
Bump Stocks and Trigger Activators
Devices built to increase a semiautomatic firearm’s rate of fire are illegal in California. That covers bump stocks and any trigger activator that lets a semiautomatic weapon fire multiple rounds with a single activation. Manufacturing, possessing, importing, selling, or lending these devices is a criminal offense.11State of California – Department of Justice – Office of the Attorney General. California Department of Justice Issues Advisory Reminding Gun Retailers That Bump Stocks Are Illegal
Carrying Without a License
Both open and concealed carry are prohibited in California without proper authorization. Carrying a loaded firearm in a public place is a misdemeanor under Penal Code 25850, punishable by up to a year in jail and a $1,000 fine. It becomes a felony carrying up to three years in prison if you have a prior felony conviction, the firearm is stolen, or you belong to a criminal street gang.
Carrying a concealed firearm without a license is a misdemeanor under Penal Code 25400, again with up to a year in jail and a $1,000 fine. Aggravating factors push it to a felony: a prior felony or firearms conviction, a stolen weapon, gang membership, or being prohibited from owning firearms. Even a prior misdemeanor for a crime against a person, a property offense, or a drug violation can lift the charge to wobbler status.12California Legislative Information. California Code PEN 25400 – Carrying Concealed Firearm
Where Guns Are Off-Limits, Even With a CCW
School Zones
The Gun-Free School Zone Act prohibits firearms on K-12 school grounds and within 1,000 feet of a school. On campus, possession carries two, three, or five years in state prison. Within the 1,000-foot perimeter, it is a wobbler: a misdemeanor with up to a year in county jail, or a felony with the same two-to-five-year prison range, depending on criminal history and the weapon.13California Legislative Information. California Code PEN 626.9 – Gun-Free School Zone Act of 1995
Sensitive Places Under State Law
Even a valid California CCW does not let you carry everywhere. Penal Code 26230 lists sensitive places where firearms are prohibited for license holders, including:
- Government buildings controlled by state executive or legislative officers, local government, or courts
- Hospitals, nursing homes, urgent care, mental health facilities, and medical offices
- Publicly funded buses and trains, plus their stations and parking areas
- Bars and restaurants that serve alcohol for on-site consumption
- Public parks, playgrounds, youth centers, athletic facilities, and adjacent streets and sidewalks
- Permitted public events and the area within 1,000 feet of them
- Preschools, childcare facilities, and K-12 schools
- Libraries, museums, amusement parks, and zoos
- Places of worship
A few of these have narrow exceptions for license holders passing through to reach their home, workplace, or vehicle.14State of California – Department of Justice – Office of the Attorney General. Additional Restrictions on CCW License Holders – Sensitive Places
Private Property
Private property owners can prohibit firearms through signage or direct notice. Entering armed against the owner’s stated wishes can bring trespassing charges on top of any firearms issue.
Getting a San Diego County CCW
San Diego County residents apply through the San Diego County Sheriff’s Department. You must be at least 21, live in the county, and have no disqualifying criminal convictions or active restraining orders. Every firearm you want to carry has to be listed on your application by make, model, serial number, and caliber, and each one must match California Department of Justice records.15San Diego County Sheriff. Carry Concealed Weapons (CCW) License
New applicants need at least 16 hours of training. The course covers safe handling, shooting technique, storage, legal transport, where permit holders can and cannot carry, and the legal standards for using lethal force in self-defense. At least one hour addresses mental health awareness and resources. There is also a live-fire component where you demonstrate proficiency with each firearm on your application. Renewals require at least eight hours covering the same material.16California Legislative Information. California Code PEN 26165 – Course of Training for License
Applications go through the Sheriff’s CCW Pro system online. Paper applications are no longer accepted. After filing, you are scheduled for an in-person appointment that includes a background investigator interview and livescan fingerprinting for state and federal checks. You pay the application fee and a separate livescan fee at or before the appointment, and the Sheriff sets fees for full cost recovery, so plan on several hundred dollars once application, fingerprinting, and state pass-through costs are added together. The fees are generally non-refundable.17San Diego County Sheriff. CCW PRO
The timeline from application to decision can run several months depending on volume and the depth of the investigation. Once the background check clears, the department will send instructions to complete your safety course if you haven’t already and pay any remaining balance. If denied, you receive a written explanation and information on appeal options. Check the portal regularly so you do not miss document requests.
Red-Flag Orders Can Strip Your Rights Without a Conviction
California’s Gun Violence Restraining Order (GVRO) law lets courts order a named person not to own, buy, possess, or receive firearms, ammunition, or magazines. Family members, household members, employers, coworkers, teachers, and law enforcement can all petition when they believe someone poses a significant danger to themselves or others.18California Legislative Information. California Code PEN 18100 – Gun Violence Restraining Order
If a GVRO is entered against you, you have to surrender all firearms and ammunition to law enforcement or a licensed dealer. Temporary emergency orders can issue the same day based on law enforcement testimony; longer-term orders require a hearing where you can respond. Holding on to weapons or acquiring new ones in violation of a GVRO is a separate criminal offense, and San Diego law enforcement uses the tool regularly.
Traveling With a Firearm
Driving
If you are driving through or out of California with a firearm, the federal Firearm Owners Protection Act gives you a safe-passage rule. Under 18 U.S.C. 926A, you can transport a firearm from one place where you may legally possess it to another, so long as the gun is unloaded and neither the firearm nor the ammunition is readily accessible from the passenger compartment. In a vehicle with no separate trunk, the firearm and ammunition have to be in a locked container other than the glove box or center console.19Office of the Law Revision Counsel. 18 USC 926A – Interstate Transportation of Firearms
This protection is narrower than it sounds. It covers transit, not extended stops. An overnight stay in a jurisdiction where your firearm is illegal may fall outside its reach. California’s own rules also require handguns transported within the state to be locked in a container in the trunk.
Flying Out of San Diego International
TSA requires firearms in checked baggage to be unloaded and locked in a hard-sided container that completely prevents access. You must declare the firearm and any ammunition to the airline at the ticket counter. A firearm counts as loaded when a live round or component of one is in the chamber, cylinder, or an inserted magazine, and TSA also treats it as loaded when the gun and ammunition are both accessible to the passenger. Original factory packaging usually does not meet TSA’s container standard.20Transportation Security Administration. Transporting Firearms and Ammunition
Airlines can add their own restrictions and fees, so call your carrier before you leave. Firearms are never allowed in carry-on luggage.
One Federal Warning Worth Repeating
Buying a gun on behalf of someone else who is prohibited, or who wants to avoid the background check, is a federal straw purchase under 18 U.S.C. 932. The penalty runs up to 15 years in prison and a $250,000 fine, rising to 25 years if the firearm is used in a felony, a terrorism offense, or a drug trafficking crime.21Office of the Law Revision Counsel. 18 USC 932 – Straw Purchasing of Firearms If a friend or family member asks you to put a gun in your name for them, the right answer is no.
