Can You Keep a Gun in Your Car at the Post Office (or Work)?

A normal Saturday of errands can be a legal obstacle course for a car carrier. Drop a package at the post office. Swing by the VA clinic. Grab the kids from school. Stop at the office to pick up a laptop.

Most carriers know they can’t walk into some of those places armed. What trips people up is the parking lot. “I’ll just leave it in the car” works in a lot of places, but not all of them, and a few of the exceptions are federal.

Here’s where the line actually sits, starting with the one that surprises people most.

Can you carry a gun in a post office?

No, and the rule reaches further than the lobby. A Postal Service regulation, 39 C.F.R. § 232.1(l), says that no person on postal property may “carry firearms, other dangerous or deadly weapons, or explosives, either openly or concealed, or store the same on postal property, except for official purposes.”

Notice the word “store.” That’s what catches car carriers. The regulation applies to all real property under the Postal Service’s charge and control, and a violation can mean a fine, up to 30 days in jail, or both.

What about the parking lot?

The big case here is Bonidy v. United States Postal Service. A Colorado man with a concealed carry permit wanted to keep his handgun in his car in the post office lot in Avon, Colorado. In 2015, the Tenth Circuit upheld the ban for both the building and the parking lot, treating the lot as part of the same facility.

That ruling came before the Supreme Court’s 2022 Bruen decision changed how courts judge gun laws, and the question isn’t dead. In 2024, a federal judge in Florida ruled in United States v. Ayala that the federal ban on guns in federal facilities was unconstitutional as applied to an ordinary post office. But one trial court’s ruling doesn’t change the rules everywhere else.

Our take: until the law clearly changes where you live, treat the post office lot as off-limits. Park on a public street that isn’t part of the property, or mail that package on a day the gun stays home.

One gray area: if the post office is a storefront in a shopping center, the shared lot may belong to the shopping center, not the Postal Service. You usually can’t tell from the driver’s seat, so we wouldn’t bet on it.

Federal buildings and VA facilities

Federal law, 18 U.S.C. § 930, makes it a crime to knowingly bring a firearm into a federal facility, punishable by up to a year in prison. The law defines a federal facility as a building, or part of one, that the federal government owns or leases and where federal employees regularly work. Notice of the ban has to be posted at each public entrance.

That statute is about buildings. Parking lots depend on the agency that controls them, and some agencies go further. The Department of Veterans Affairs, for example, bans carrying firearms “either openly or concealed” anywhere on VA property, and its rules treat parking areas as part of that property. If you’re headed to a VA medical center, the car isn’t a safe harbor.

Federal courthouses have their own, stricter rule. Don’t even think about it.

The National Mall and DC monuments

Visiting the monuments with a DC license? DC’s own law bans carrying at the public memorials on the National Mall and along the Tidal Basin, at the White House complex and its grounds, and in any area where firearms are banned by federal law or a federal agency. Federal buildings on and around the Mall fall under the federal facilities ban too.

If you’re driving in for a monument day, secure the gun in the car the way DC requires before you head out on foot, or leave it at home. Our Washington, DC carry laws guide has the full list.

School pickup in DC

This one catches parents. DC’s list of prohibited places includes the building and grounds of schools and childcare facilities, “including any adjacent parking lot.” So pulling into the school lot for pickup counts. Secure the gun the way DC requires before you get there. For Maryland, Virginia, and other cities, check our guide to no-carry zones in your city.

Your employer’s parking lot

Some states have so-called parking lot laws that protect employees who keep a gun locked in their own car at work. Many states don’t. Virginia is one of them, according to a 2018 analysis by the employment law firm Littler, and since July 1, 2026, Virginia’s unattended-vehicle law also applies in parking areas reserved for commercial or retail employees. Leave a handgun in the car at work there and it has to be out of plain view in a locked, hard-sided container.

Where there’s no parking lot law, your employer’s weapons policy can cover the company lot. Breaking it might not be a crime, but it can absolutely cost you your job. Read your handbook, and if it’s unclear, ask HR before you assume. More on this in our guide to concealed carry for professionals at work.

An errand-day playbook

• Look at your route before you leave. Post office, VA, federal building, or school on the list? Plan around it.
• Read the signs at the entrance, including the driveway, not just the front door.
• Park off the property when you can, on a public street that isn’t part of the site.
• Do the federal stops on a no-carry day if they keep stacking up.
• Use a car safe for everywhere else. A locked, hard-sided safe attached to the car handles most no-carry stops. It doesn’t fix the post office or VA lot, because the rule there is about the property itself.

Federal property FAQ

Can I leave my gun locked in my car at the post office?

The Postal Service’s rule bans storing firearms on postal property, and the Tenth Circuit upheld that rule for a post office parking lot in 2015. Park somewhere else.

Is every federal parking lot off-limits?

Not automatically. The main federal statute covers buildings, and lots depend on the agency’s own rules. Some agencies, like the VA, ban weapons on all their property. Check the signs and the agency’s rules.

Didn’t a court strike down the post office ban?

One federal trial judge in Florida ruled in 2024 that the federal facilities ban was unconstitutional as applied to an ordinary post office. That ruling doesn’t change the law in Maryland, Virginia, DC, or anywhere else.
