About Sign

Hill

Sign Hill, located between Downtown South San Francisco and Oyster Point, is a hillside and industrial-edge South San Francisco neighborhood with the iconic hillside letters and bay-facing trails. The neighborhood’s character concentrates at the Sign Hill Park trailhead off Chestnut Avenue, where switchbacks, wind-swept overlooks, and the white “South San Francisco The Industrial City” sign set the tone. Housing leans to mid-century streets and compact lots, with warehouse blocks and light-industry corridors nearby. The ridge reads as a daily compass point, with planes tracing the sky and the Bay framing the horizon. For a local night out, the community’s pillars include Grand Avenue’s Orange Memorial Park, the historic South San Francisco Conference Center, and the long-running Basque spot Amoura Restaurant.
