858-862 Union St, San Francisco, CA 94133

The three-story multi-family residential building at 858-862 Union Street in Russian Hill, owned by Mash Abbas & Mofrad Dalileh, is a four-unit flats and duplex structure built in 1907. The building has experienced several significant maintenance and safety issues in recent years, most notably in early 2023 when at least three wind-damaged broken flue pipes on the rooftop created safety concerns regarding debris falling hazards. This followed earlier ventilation issues documented in mid-2022, and heating system violations in late 2012 when the building failed to maintain required heat levels and smoke detector compliance, leading to official notices and a mandatory heating system replacement completed in 2013.

The property has a history of addressing necessary improvements, including roofing work in 1989 and aluminum window installations in 1986, though some issues have recurred, such as the 2022 and 2023 rooftop vent concerns. The building's recent history shows particular attention to ventilation and heating system issues, with multiple complaints and violations related to these systems between 2012 and 2023. Additional maintenance history includes a sewage backup incident in 2004 and various routine inspections.

The property has experienced frequent issues with parking enforcement in the vicinity, with multiple citations issued for driveway blocking between 2020 and 2023, though these are not directly related to building maintenance or resident safety. While recent building permits indicate some ongoing maintenance attention, the pattern of recurring ventilation issues suggests a need for continued monitoring of building systems. The property has had two categorized fire complaints, though both were found to have no merit or were referred to another agency.
