460-464 Union St, San Francisco, CA 94133

460-464 Union Street is a 3-story multi-family residential building constructed in 1908, consisting of 6 units and located in San Francisco's Telegraph Hill neighborhood. The property, currently owned by Lou Shuxian & Zhou Yanchun, has undergone several significant renovations and faced multiple regulatory challenges over the past two decades. Most recently, in 2018, there was a kitchen remodeling project costing $20,383, though associated plumbing permits from that period have since expired.

The building has experienced several concerning incidents, particularly during unauthorized construction work in 2018 that reportedly caused an accidental fire and involved non-contracted workers, which is currently listed as an active complaint. Additionally, there was a complaint in 2016 regarding unpermitted modifications to a roof access doorway. The property's maintenance history reveals some serious historical concerns, with violations recorded in 2011 related to interior paint conditions and potential lead paint hazards, though these were subsequently addressed.

Earlier routine inspections in 2005 raised issues regarding emergency exits and smoke detectors, which were also resolved. Two alarm system malfunctions were recorded in 2009 and 2008, but no civilian injuries were reported. The building's recent history shows consistent parking enforcement issues, with numerous citations for driveway blocking recorded between 2022 and 2024, though these are not directly related to building conditions. A window replacement permit from 2007 and various citations for parking violations in the surrounding area (totaling around 11 cases in 2022-2024) are also part of the building's permit and complaint history.
