In 2026, traveling safely in San Francisco requires a "common sense" approach focused on vehicle security and situational awareness. The most prevalent issue is "smash-and-grab" auto burglaries; the universal rule in 2026 is "If you love it, don't leave it." Never leave even a small bag or a jacket visible in a parked car, especially in tourist hubs like Fisherman’s Wharf or the Painted Ladies. For personal safety, use the "AlertSF" text system for real-time emergency updates. When using public transit like MUNI or BART, keep your phone put away to avoid "snatch" thefts. While neighborhoods like the Tenderloin and parts of South of Market (SoMa) have high concentrations of homelessness and open drug use, most visitors find that staying on well-lit main thoroughfares and using ride-shares like Uber or Waymo (autonomous taxis) at night ensures a safe experience. In 2026, the city has increased "Ambassador" patrols in downtown areas to assist tourists and provide a visible security presence.
