San Francisco Airport (SFO) is a completely smoke-free facility. Smoking and vaping are not allowed anywhere inside the terminal buildings, including lounges, dining areas, restrooms, and gate zones.
For those who do smoke, designated outdoor smoking zones are available:
- These areas can be found outside the terminals, both on the Departures (upper) and Arrivals (lower) levels.
- Look for marked spots near the terminal entrances — signs and ashtrays are provided to guide travelers.
- Please keep in mind that to access these smoking spots, you must exit the terminal, which means you’ll need to go through security screening again if you’re continuing your journey.
🚫 SFO does not provide indoor smoking lounges, so all smoking must take place in clearly marked outdoor areas only.
