In most of Texas, whether you can smoke inside comes down to the city you’re in and the property owner’s rules, because state law only bans indoor smoking in a short list of specific places. Penal Code Section 48.01 covers schools, elevators, enclosed theaters, libraries, museums, hospitals, and public transportation, and stops there. Restaurants, bars, offices, and stores are not on the statewide list, so a local ordinance or a “No Smoking” sign is usually what decides the question.
Where State Law Bans Indoor Smoking
Texas Penal Code Section 48.01 makes it a criminal offense to smoke tobacco, hold a lit tobacco product, or use an e-cigarette in these public places:1Justia. Texas Penal Code Chapter 48 – Conduct Affecting Public Health
- Public primary and secondary schools
- Elevators
- Enclosed theaters and movie houses
- Libraries
- Museums
- Hospitals
- Public transportation: transit buses, intrastate buses, planes, and trains
That is the complete statewide list, and it is shorter than most people expect. Public school campuses get an added layer of protection under Texas Education Code Section 38.006, which makes them tobacco-free and extends the ban to school-related activities off campus as well.2Texas Department of State Health Services.

Everywhere else? State law says nothing. If no city rule applies, the property owner decides.
How Cities Fill the Gap
Texas explicitly allows local governments to be stricter than state law. As of the most recent state count, 107 of Texas’s 1,220 municipalities have adopted comprehensive smoke-free ordinances.3Texas Department of State Health Services. 2025 Electronic Cigarette (E-Cigarette) Report Houston, Austin, San Antonio, Dallas, and El Paso all fall in that group, so indoor smoking is generally off-limits in their restaurants, bars, and workplaces.
Drive a short distance to an unincorporated area or a smaller town without an ordinance, and the same activity may be perfectly legal. The one clear limit on local rulemaking is that cities cannot ban smoking at businesses where at least 20 percent of revenue comes from cigar sales.
The practical takeaway is simple: check the local rule before you assume anything. What is fine in one Texas city can be a citable offense fifteen minutes down the highway.
Common Exceptions Inside Smoke-Free Cities
Even the stricter city ordinances carve out places where indoor smoking is still allowed. Houston’s ordinance is a useful reference because other Texas cities have followed a similar template. Its exemptions include:4City of Houston. Smokeless Tobacco Redline
- Hotel guest rooms designated for smoking, capped at 35 percent of rooms, on contiguous floors, with ventilation that keeps smoke out of nonsmoking areas
- Retail tobacco stores that do not serve alcohol and keep smoke out of restricted areas
- Tobacco bars grandfathered from before September 1, 2006, with approved ventilation, employee health insurance, and a city permit
- Private function spaces at hotels and convention centers during private events, with separate ventilation
Outdoor areas near doors are also regulated in most of these cities. Houston requires 25 feet from entrances, exits, and operable windows. Other cities use 20 or 50 feet. Stepping outside the front door and lighting up right next to it can still be a violation.
Workplaces, Homes, and Rentals
Texas has no state law requiring private workplaces to be smoke-free. In cities with comprehensive ordinances, indoor smoking is banned in nearly all workplaces. Outside those cities, employers set their own policy.
The Americans with Disabilities Act specifically states that nothing in it prevents an employer from banning workplace smoking. Because respiratory function is a major life activity under the ADA, an employee with a respiratory condition can request a smoke-free environment as a reasonable accommodation.5ADA.gov. Americans with Disabilities Act of 1990, As Amended
In your own home, state and local laws generally leave you alone. Renters are a different story: a lease can prohibit indoor smoking, and violating that clause can support eviction. Homeowners’ associations can restrict smoking in shared indoor areas.
Federally funded public housing is stricter. HUD requires every public housing agency to maintain a smoke-free policy covering living units, hallways, offices, community centers, and laundry rooms, and to prohibit smoking within 25 feet of the buildings.6eCFR. Subpart G – Smoke-Free Public Housing
Vaping Is Treated the Same
Penal Code 48.01 explicitly covers “operating an e-cigarette” alongside smoking tobacco. Anywhere state law bans smoking, it bans vaping.1Justia. Texas Penal Code Chapter 48 – Conduct Affecting Public Health City ordinances almost always follow the same approach, so if a local law bans indoor smoking, assume vaping is included unless you have confirmed otherwise.
On age, Texas law makes it an offense for anyone under 21 to possess, purchase, or use an e-cigarette or tobacco product.7Texas Public Law. Texas Health and Safety Code Section 161.252 – Possession, Purchase, Consumption, or Receipt of Cigarettes, E-Cigarettes, or Tobacco Products by Minors Prohibited A separate provision protects retailers who sell to someone 18 or older with a valid U.S. military ID, but that carveout shields the seller, not the buyer.8State of Texas. Texas Health and Safety Code Section 161.082 – Sale of Cigarettes, E-Cigarettes, or Tobacco Products to Persons Younger Than 21 Years of Age Prohibited
Federal Bans That Apply Anywhere in Texas
Federal regulations ban smoking and vaping on all commercial flights, including while the aircraft is on the ground. The rule covers traditional tobacco, e-cigarettes, and any device that produces smoke, vapor, or aerosol, and airlines are required to monitor lavatories.9eCFR. Part 252 – Smoking Aboard Aircraft
The HUD public housing rule applies throughout Texas as well. Indoors and within 25 feet of the buildings, smoking is prohibited.
Fines and Two Defenses Worth Knowing
A violation of Penal Code 48.01 is a Class C misdemeanor, punishable by a fine of up to $500 with no jail time.1Justia. Texas Penal Code Chapter 48 – Conduct Affecting Public Health The statute also provides two defenses. If the location does not have a prominently displayed sign stating that smoking is prohibited by state law and that violations carry a fine of up to $500, that is a defense to prosecution. If the location fails to provide receptacles for extinguishing smoking materials, that is also a defense.
These defenses apply only to the specific state-law locations. They do not help against a local ordinance charge, which has its own enforcement rules. Local fines typically run from $100 to $500 per violation, and business owners who fail to enforce a smoke-free ordinance can face larger fines and, in some cities, permit consequences after repeated violations. If you run a business in a smoke-free city, enforcement is on you, not just on the customer holding the cigarette.
