In 1888, this building hummed as the California Electric Light Company's Station B, the plant that arced San Francisco's very first electric streetlights to life and gave Arc Light its name. It survived the 1906 earthquake, anchored the city's South End Historic District for over a century, and today stands reimagined as sixty-plus loft residences layered beneath a striking modern glass addition.
Exposed brick, soaring ceilings, and oversized windows carry the building's industrial DNA into every home, flooding each residence with natural light. Layer in thoughtfully designed studio, 1-, 2-, and 3-bedroom floor plans, elevated amenities, and an unbeatable South Park location, and Arc Light brings together everything you need for a life that's as dynamic and as singular as the building itself.
