519 Natoma St, San Francisco, CA 94103

The property at 519 Natoma Street is a two-story, four-unit multi-family residential building constructed in 1907 in San Francisco's South of Market neighborhood, currently owned by Byron Aftonomos Lefkos since 2010. The building underwent significant improvements in 2004, including a $150,000 renovation to upgrade the exit stair at the rear and infill the light wells, as well as a $60,000 project to replace kitchens and bathrooms in all four studio apartments while upgrading electrical and plumbing systems. A major electrical upgrade was completed in 2005, involving rewiring all four apartments with new lighting, switches, and receptacles.

The building has had three notable fire safety-related incidents: a cooking fire (contained), a smoke scare, and one false alarm, with no civilian injuries reported in any of these events. The property has undergone several safety inspections and renovations over its history, including addressing dry rot damage repairs to rear stairs in 1992. In 2004, multiple building violations were documented and subsequently abated, including issues with stairs, fire sprinklers, and gas shutoff tools.

A routine safety inspection in 2008 and a health and safety inspection in 2011 resulted in additional requirements for fire safety improvements and security devices, all of which were eventually resolved. More recently, 2023-2024 records show various municipal service calls near the property, including reports of encampments, illegal parking, and street cleaning issues, though these are primarily external to the building itself. The most recent building-related permits show limited recent activity, with the most recent being a street space permit issued in 2018, suggesting stable conditions since the last major renovations.
