The Firearms Ordinance states that no gun can be discharged within City Limits or ETJ, with the following exceptions:
If your property was annexed after 09/01/1981 or you are located in the Extra Territorial Jurisdiction (ETJ), expect for the protection of a person or property in or about your home, or for an exhibition during a charitable contest with prior approval of city council after an application has been made and permit has been issued. Discharging shotguns, air or bb guns and/or bow and arrow on 10 acres minimum lots is permitted at any time as long as they are discharged at least 150 feet from a residence or occupied building located on another property and all projectiles must remain within the property lines of land on which it was discharged. For rim fire, centerfire, or any pistol shooting, it must occur on 50 acres or more, at least 300 feet from a residence or occupied building located on another property and all projectiles must remain within the property lines of land on which it was discharged.
If a firearm is discharged in the protection of your life, your family, or your property as allowed by the Texas State Penal Code, the incident will be investigated by police officers to determine the discharge was justified in accordance with the law. Any bullet discharged from a firearm is the responsibility of the firearm handler at that time. Any damage cause by the projectile is the responsibility of the firearm handler, and that person will be prosecuted accordingly to the law. A firearm handler will likely face serious charges for any injuries occurring as the result of an errant or misdirected projectile.
