310 Filbert St, San Francisco, CA 94133

The two-unit multi-family residential building at 310 Filbert Street in Telegraph Hill, owned by the Gray Family Trust, is a two-story flats and duplex structure dating back to 1900. The property has undergone significant renovations and faced multiple maintenance challenges over the years, with the most substantial work occurring in 2010-2011. This included a $79,000 interior renovation in 2010 addressing multiple bathrooms and kitchen updates in response to a 2003 violation, along with complete electrical rewiring and panel upgrade, bathroom/kitchen plumbing work, and the construction of a new concrete retaining wall.

The building previously experienced serious sewer issues in 2003, which were officially noted as a health and safety hazard due to sewage overflow affecting neighboring properties, though this violation was ultimately abated in 2014. Other notable improvements included the enclosure of rear stairs and deck improvements in 2010, conversion of two interior doors to pocket doors in 2008 to address water leak issues around a main floor skylight, and the replacement of furnaces that same year. Recent activity at the property has been minimal, with only minor infrastructure-related issues reported through 311 calls, including street cleaning requests and sign maintenance matters.

The most recent documented concern was a damaged property report from January 2024 that was administratively closed due to technical issues. The building's major systems have been upgraded and maintained through various permits, showing a history of responding to both mandatory corrections and routine improvements, though some permits from 2010 related to street space usage remain listed as issued but not marked as finalized. The property has maintained compliance with health and safety regulations since addressing the significant 2003 sewer problem, with no active violations on record. The extensive renovation work performed in 2010-2011 appears to have substantially modernized the building's systems and living spaces, restoring compliance with building codes and improving resident amenities.
