797-799 De Haro St, San Francisco, CA 94107

The three-story multi-family residential building at 797-799 De Haro Street in Potrero Hill, constructed in 1978, contains two units and is currently owned by Hu Herman & Seid Marylee Trust. The building's maintenance history shows a completed re-roofing project from 1999, but the most significant issues emerged between 2006-2008 when multiple building violations were documented, all stemming from a single complaint filed on July 5, 2006.

These violations included inadequate heating systems, window repair needs, insufficient lighting, interior surface problems, damaged ceilings, and handrail repairs, all of which were eventually abated by September 30, 2008. More recent incidents in the building's vicinity include several 311 calls regarding various urban issues between 2019 and 2024, though none specifically related to the building's condition or safety.

These external issues ranged from illegal parking and sign defacement to a pavement defect in 2024. Three fire incidents have been recorded near the address, including non-injury situations involving barbecue smoke, a false alarm, and an electrical wiring/equipment problem, none of which resulted in civilian injuries. While the building had significant maintenance issues in the mid-2000s, there have been no documented housing code violations or serious building complaints in recent years, suggesting improved maintenance conditions.
