418-420 Corbett Ave, San Francisco, CA 94114

The property at 418-420 Corbett Avenue is a two-unit, two-story multi-family residential building constructed in 1938, currently owned by the Heitner-O'Connell Trust. The building has experienced recurring issues with dry rot and water damage over the years, with the most recent significant repairs occurring in December 2022 to address fungus and termite damage behind the stucco, and in 2019-2020 for water-related bathroom renovations and electrical panel upgrades.

A series of violations and complaints in 2011-2013 regarding unpermitted construction work, including window installations and exterior wall modifications, required multiple permits and corrections, though these issues were eventually resolved. The building underwent a complete reroofing in 2007, and notable recent improvements include electrical upgrades in 2020 with new meter sections and panels.

The property has experienced various maintenance and compliance challenges, including multiple instances of false fire alarms and system malfunctions recorded between 2020-2023, though none resulted in civilian injuries. Recent exterior issues have been documented through 311 calls, primarily related to graffiti and public space maintenance, with several cases remaining open as of early 2025. While the building's maintenance history shows ongoing attention to structural and safety issues, particularly regarding water and pest damage, there have been relatively few major health or safety violations in recent years, with the most pressing concerns being the recurring nature of dry rot repairs and the recent electrical upgrades indicating an effort to maintain and improve building systems.
