766 De Haro St, San Francisco, CA 94107

The two-story multi-family residential building at 766 De Haro Street in Potrero Hill, owned by George D & Thelma Giannakar, was constructed in 1912 and has no official unit count recorded. The property has exhibited several concerning maintenance issues, most notably a recent complaint filed in March 2024 regarding faulty gas stove ventilation and a significant hole between the wall and floor in the back sunroom, though this case is currently listed as not active.

The building's exterior and surrounding infrastructure have experienced recurring problems, particularly with the sidewalk, which has been the subject of multiple 311 calls between 2021 and 2022 for defects including lifting and collapse, with one case remaining open as of August 2022. Earlier incidents include a 2015 report of automotive debris, a flickering streetlight in 2014, and two separate complaints in 2011 regarding garbage cans being left out continuously.

The only building permit on record is from 1992 for reroofing work, though this permit has since expired. While some of these issues are relatively minor and have been resolved, the recent complaints about ventilation and structural openings suggest potential concerns regarding resident comfort and safety.
