Businesses must obtain a mixed beverage permit from the Texas Alcoholic Beverage Commission. They must also comply with local zoning laws and ordinances.To obtain a new permit or license you must complete the TABC applications and pay associated fees. We want to help you understand the laws, rules and regulations for the alcoholic beverage industry. By working together, we can keep Texans safe. Texas's DWI laws are stringent, with penalties increasing with the severity of the offense. There are no statewide bring-your-own-beverage (BYOB) laws in Texas. Check with your city or county for relevant local ordinances. The law prevents us from providing legal advice to any person. Please see the Bexar County Probate Courts website for more information. 11.
