Sector San Francisco

Sector San Francisco is a United States Coast Guard unit responsible for maritime safety, security, and environmental protection in the San Francisco Bay Area and surrounding Northern California waters. Established in 2004 as part of the Coast Guard’s sector reorganization, it combined the responsibilities of several legacy units, including the former Marine Safety Office San Francisco Bay and Group San Francisco. The unit oversees search and rescue operations, vessel inspections, pollution response, and port security across one of the nation’s busiest and most strategically important harbors. Sector San Francisco has played a critical role in safeguarding maritime commerce, responding to environmental incidents, and supporting national security initiatives in the region.
