Vaping in a restaurant is illegal in roughly 20 states, the District of Columbia, Puerto Rico, and hundreds of cities and counties that have folded e-cigarettes into their smoke-free indoor air laws. No federal law bans it, so whether you can legally use a vape at your table depends on the state you’re in, the local ordinance where the restaurant sits, and the restaurant’s own policy. Even where the law is silent, the owner can tell you to stop or leave.
Where Indoor Vaping Is Banned by Law
As of late 2024, 20 states, the District of Columbia, and Puerto Rico have comprehensive smoke-free indoor air laws that specifically include e-cigarettes and prohibit their use in private workplaces, restaurants, and bars.1Centers for Disease Control and Prevention. STATE System E-Cigarette Fact Sheet In those jurisdictions, anywhere smoking was already banned, vaping is banned too.
The remaining states either leave e-cigarettes out of their smoke-free laws or have no comprehensive indoor air law at all. That is where cities and counties often step in. Hundreds of municipalities have amended local smoking ordinances to cover e-cigarettes, and local rules are frequently stricter than state law. A city can ban vaping in all enclosed public spaces, including restaurants and bars, even if the state legislature hasn’t acted.
Checking state law alone isn’t enough. Local health department and city government websites usually post the current rules, and that’s the fastest way to confirm what applies at a specific address.
One wrinkle cuts the other direction. A handful of states have passed preemption laws that prevent cities and counties from enacting their own e-cigarette restrictions. In those states, if the legislature hasn’t banned indoor vaping, local governments can’t fill the gap.
Patios and Outdoor Seating
Most indoor air laws apply to enclosed spaces, so outdoor patios and sidewalk seating often fall outside the ban. Some jurisdictions have extended their restrictions to outdoor dining areas, particularly when the space is partially enclosed or attached to the building. Even where the law doesn’t reach the patio, the restaurant can prohibit vaping there on its own. When you’re unsure, ask a server before taking out a device.
The Restaurant Can Ban Vaping Regardless of the Law
A restaurant in a state with no vaping restrictions can still post a no-vaping policy and enforce it. Staff can ask you to stop, and if you refuse, they can ask you to leave. Staying after being told to leave turns a policy dispute into a trespassing issue, which is a criminal matter in every state.
Most restaurants that allow vaping do so passively, simply by not posting a policy. That silence isn’t permission. If a staff member asks you to stop, the restaurant’s authority to enforce the request is the same whether or not a sign is posted.
Fines and Other Penalties
If no law applies and you’re only breaking a house rule, the worst that happens is being asked to leave. Refuse, and you risk a trespassing charge.
When you violate a state or local indoor vaping ordinance, the penalties are usually civil fines rather than criminal charges. Amounts vary widely by jurisdiction. First-offense penalties for individuals commonly start in the low hundreds of dollars and climb for repeat violations.
Many of these laws also penalize the business for failing to enforce the ban. Owner fines tend to be significantly steeper, sometimes reaching several hundred to a few thousand dollars per violation after an initial warning period. Repeat enforcement failures can trigger escalating penalties or action from local health authorities. That is part of why a restaurant with no personal reason to care about your vape may still have a strong reason to ask you to put it away.
