Houston Gun Laws: Carry, Vehicles, and Prohibited Places

Houston gun laws are, with very few exceptions, Texas gun laws. State preemption blocks the city from writing its own rules on who can own, carry, or store firearms, so the framework that applies inside the Loop is the same one that applies across the rest of the state. If you are 21 or older and not otherwise disqualified, you can carry a handgun in public without a license, keep firearms in your home and vehicle, and use deadly force in defined self-defense situations. What changes from place to place is where you can take a firearm and how a property owner has posted their premises.

Who Can Legally Have a Firearm

Eligibility runs on two tracks, federal and state, and you have to clear both.

Federal law lists nine categories of people barred from possessing firearms or ammunition. The ones that come up most often: a felony conviction (any crime punishable by more than one year in prison), being a fugitive, being an unlawful user of controlled substances, having been involuntarily committed to a mental institution, being subject to certain domestic violence protective orders, and having been convicted of a misdemeanor crime of domestic violence.¹ The domestic violence misdemeanor ban has no exception for government employees, and violating it carries up to 15 years in prison.²

Texas adds its own layer. Under Penal Code Section 46.04, a person convicted of a felony cannot possess a firearm at all during the first five years after release from confinement or community supervision, whichever ends later.³

Age

You generally must be 21 to carry a handgun in public. People aged 18 to 20 can legally possess a handgun on their own property, inside their own home, or inside a vehicle they own or control, as long as the handgun stays out of plain view.⁴ Long guns like rifles and shotguns can be possessed by anyone 18 or older who is not otherwise disqualified.

Carrying a Handgun in Houston

Since September 2021, Texas has allowed permitless carry. If you are 21 or older and legally eligible to possess a firearm, you can carry a handgun in public without a state-issued license.⁵

Eligibility is not a one-time check. You lose the right to carry if you pick up a felony conviction or are convicted of certain misdemeanors within the preceding five years, including assault causing bodily injury, deadly conduct, or making terroristic threats.⁴

If you carry openly, the handgun must be in a holster. Displaying a handgun in plain view without a holster in a public place is a Class A misdemeanor, punishable by up to a year in jail and up to $4,000 in fines.⁴⁶ Concealed means the weapon stays hidden from ordinary observation.

Why the License to Carry Still Matters

The LTC is optional but useful. Many states with reciprocity agreements will honor a Texas LTC but will not recognize permitless carry from another state.⁷ An LTC also gives you access to certain locations where unlicensed carriers are restricted, including some areas near schools and on college campuses. The application fee is $40 for both original licenses and renewals.⁸

Guns in Your Vehicle

Texas treats vehicles as an extension of your personal space, but the rules depend on your age and license status. If you are 21 or older, or hold an LTC, you can have a handgun visible inside your vehicle as long as it’s in a holster.⁴ If you are 18 to 20 with no LTC, you can still have a handgun in a vehicle you own or control, but it must be concealed from plain view. Having a handgun visible without a holster while under 21 and unlicensed is a Class A misdemeanor.

Regardless of age or license status, you cannot have a firearm in your vehicle if you are engaged in criminal activity beyond a minor traffic violation or if you are legally prohibited from possessing firearms at all.⁴

Places Where Firearms Are Off-Limits

Some locations are prohibited by statute no matter who you are or what license you hold. Texas Penal Code Section 46.03 lists them, and violations are generally charged as third-degree felonies, punishable by two to ten years in prison and up to $10,000 in fines.⁹¹⁰ The prohibited locations include:

K-12 school premises and school transportation vehicles. Rules differ slightly for LTC holders at postsecondary institutions that allow concealed carry on campus.
Polling places during any election or early voting period.
Courtrooms and offices used by the court.
The premises of any licensed racetrack.
Past the security checkpoint at any commercial airport.
Businesses that earn 51% or more of their revenue from on-premises alcohol consumption. These post a red “51%” sign.
High school, collegiate, and professional athletic events, unless you’re a participant using the firearm in the event.
Correctional and civil commitment facilities.
Hospitals and nursing facilities, unless you have written authorization from the administration.
Mental health facilities.
Amusement parks.
Rooms where a governmental body holds a meeting open to the public under the Texas Open Meetings Act.

The bar prohibition trips people up most often. If you see the red “51%” sign on the door, your firearm stays outside regardless of your license status.

Federal Property

Houston has plenty of federal buildings, courthouses, post offices, and VA facilities. Federal law prohibits firearms in any federal facility, with conviction carrying up to one year in prison.¹¹ Federal court facilities carry up to two years, and bringing a weapon in with intent to commit a crime can bring five. Post offices prohibit both carrying and storing firearms on their premises, including in parking lots.¹² Your Texas LTC or permitless-carry rights do not override any of this.

Private Property and Posted Signs

Property owners can ban firearms using specific signage defined by the Penal Code. Three different signs are in circulation, and they don’t all cover the same people:

A 30.06 sign prohibits concealed carry by LTC holders on the premises.¹³
A 30.07 sign prohibits open carry by LTC holders on the premises.¹⁴
A 30.05 notice is used for criminal trespass more broadly, including prohibiting entry by people carrying without a license.

The signs must include specific language in both English and Spanish, in contrasting colors, with block letters at least one inch tall.¹⁴ One distinction many people miss: 30.06 and 30.07 signs technically only apply to people carrying under an LTC. A business posting both but not 30.05 has restricted licensed carriers and left permitless carriers unaddressed.¹⁵

Ignoring a properly posted sign is initially a Class C misdemeanor with a fine of up to $200. If you’re told verbally to leave and refuse, the charge escalates to a Class A misdemeanor.¹⁴

When You Can Use a Firearm in Self-Defense

Texas has broad self-defense protections, but they come with firm conditions. Owning a gun without understanding when you can legally use it is a fast route to a felony charge.

Non-deadly force is justified when you reasonably believe it’s immediately necessary to protect yourself against another person’s unlawful force. That belief is presumed reasonable if someone unlawfully and forcibly enters or tries to enter your home, vehicle, or workplace, or tries to forcibly remove you from any of them.¹⁶ The same presumption applies if someone is committing or attempting murder, robbery, sexual assault, or kidnapping against you.

Deadly force is justified when you reasonably believe it’s immediately necessary to protect yourself against another person’s use of deadly force, or to prevent the imminent commission of serious violent crimes like murder, aggravated robbery, sexual assault, or aggravated kidnapping.¹⁷ The same presumption of reasonableness covers deadly force in the forced-entry scenarios above.

You do not have to retreat, as long as you have a right to be where the confrontation happens, you did not provoke the other person, and you were not engaged in criminal activity at the time.¹⁷ A jury cannot hold your failure to retreat against you.

Self-defense claims fail if you responded only to verbal provocation, if you consented to the force used against you, or if you provoked the encounter and did not clearly try to disengage before things escalated.¹⁶ You also cannot claim self-defense if you were carrying a handgun in violation of Section 46.02 or possessing a prohibited weapon when you picked the fight.

Buying, Transferring, and NFA Items

When you buy from a licensed dealer in Houston, you fill out ATF Form 4473, and the dealer runs a background check through the National Instant Criminal Background Check System before the sale goes through.¹⁸ Every federally licensed dealer must run this check for every transaction.

Private sales between two individuals within Texas do not currently require a background check. That said, knowingly selling or transferring a firearm to someone who is legally prohibited is a serious crime under both state and federal law. If you sell guns often enough that it amounts to a business, you need a Federal Firearms License, and operating without one is a federal offense. When in doubt about a buyer, many FFLs in Houston will facilitate a voluntary background check for a modest fee.

Suppressors, short-barreled rifles, and short-barreled shotguns are legal to own in Texas, but they fall under the federal National Firearms Act. Each item must be registered in the National Firearms Registration and Transfer Record, and you pay a one-time $200 federal tax when making or transferring the item.¹⁹ Texas Penal Code Section 46.05 does not list suppressors or short-barreled firearms as prohibited weapons, so state law adds no additional barrier once federal registration is complete.²⁰ There is no legal way to register an NFA item you already possess unregistered; trying to do so exposes you to criminal liability.

Storing Firearms at Home

Texas has a child access prevention statute. Penal Code Section 46.13 makes it an offense to leave a firearm accessible to a child under defined circumstances.²¹ Beyond that, Texas does not impose a general safe-storage mandate. There is no state requirement to use a gun safe, trigger lock, or locked container when a firearm is in your home, and no requirement that dealers include a locking device at the point of sale.

The absence of a broad storage law does not eliminate civil liability. If a child or prohibited person gains access to an unsecured firearm and someone is hurt, a negligence claim is on the table. Keeping firearms secured when not in use, especially in a household with children or anyone prohibited from possessing firearms, protects both safety and legal exposure.

What the City of Houston Can and Cannot Regulate

Texas Local Government Code Section 229.001 strips Houston of the power to write its own rules on the sale, possession, carrying, ownership, storage, transportation, licensing, or registration of firearms or ammunition.²² Any local ordinance that conflicts with state law is void, and the city cannot even require gun owners to carry liability insurance.

Houston keeps a few narrow powers. It can regulate when and where firearms are discharged (though not at sport shooting ranges) and can restrict carrying at public parks, public meetings, political rallies, and non-firearm-related sporting events. Separately, Texas Penal Code Section 42.12 makes it a Class A misdemeanor to recklessly fire a gun inside any city with a population of 100,000 or more, which includes Houston.²³ The penalty range is up to one year in jail and a fine of up to $4,000.⁶ For every other question a gun owner is likely to ask, the answer lives in the Texas Penal Code, not a Houston municipal ordinance.
