Free public WiFi in San Francisco, branded as #SFWiFi, is available in several high-traffic areas, including Chinatown (Grant Ave, St. Mary’s Square), Market Street, Civic Center, Alamo Square, and Mission Dolores Park. Other locations include various parks, recreation centers (e.g., Duboce Park), and library branches citywide.
Key locations and details for free public WiFi:
Chinatown: Active on Grant Avenue from Bush Street to Broadway, Dragon Gate, and St. Mary’s Square. Further expansions are planned for 2026.
Major Plazas & Parks: Civic Center Plaza, Union Square, Dolores Park, and Alamo Square.
Transit & Public Spaces: Many Muni stations and Market Street.
Other Areas: High-speed access is in progress for Japantown Peace Plaza, Gene Friend Recreation Center, and Herz Recreation Center.
Library & Community Centers: All SF Public Library branches offer free Wi-Fi, along with specialized locations like the Gubbio Project in the Mission.
San Francisco is actively expanding its free public #SFWiFi network, with a major focus on enhancing digital equity in under-resourced neighborhoods through 2026.
Here are the planned expansions of free public Wi-Fi in San Francisco as of March 2026:
Chinatown Expansion (Phase 2 - 2026)
Expansion Area: Following the initial launch on Grant Avenue (between Pacific and Broadway), phase two will expand coverage to Stockton Street, including surrounding alleyways, side streets, and additional public spaces.
Upgrades: Service at Portsmouth Square will be upgraded to improve speed and coverage upon completion of planned park renovations.
Timeline: Phase two is expected by the end of 2026.
In-Home Connectivity: The project includes the "Fiber to Housing" program, which connects low-income Single Room Occupancy (SRO) units in Chinatown to free high-speed internet.
Tenderloin and Bayview Neighborhoods
Upcoming Rollout: The Department of Technology (DT) is planning to bring similar free, high-speed Wi-Fi to the Tenderloin and Bayview neighborhoods, aiming to improve access in communities that have traditionally faced slower, costlier, and less reliable internet service.
Funding: These expansions are supported by a $10.3 million state grant secured in 2024 to connect 434 unserved locations across the city.
#SFWiFi Network Upgrades
General Expansion: The city continues to enhance its existing #SFWiFi network, which is already available in over 20 parks, plazas, and commercial areas.
Infrastructure Improvements: The city is partnering with commercial internet service providers to expand coverage and is moving towards a standardized SSID for all city-owned public wireless networks to ensure seamless access.
Offline Locations: Locations currently listed as offline, such as Alamo Square, Balboa Park, and Mission Dolores Park, are slated to be addressed as funding becomes available.
BART and Transit Connectivity
Underground Wi-Fi: BART is working to complete its Digital Railway program, aiming to install free Wi-Fi in all downtown San Francisco stations and, by 2025, install service-boosting poles along routes to enable internet access in the underground, where cellular service is currently limited.
