Augrented Insights Report

The 5-unit, 3-story multi-family residential building at 19-23 Salmon Street in Nob Hill, owned by Edison K F Tseng, was constructed in 1907 and has experienced several maintenance and safety issues over recent years. Most concerning was a series of violations and complaints in 2024 (now resolved) related to water damage, including mold and mildew on ceilings and walls, and damaged walls and ceilings, reportedly caused by plumbing issues.

The building has also faced persistent ventilation problems, with multiple violations (2021-2024) concerning improperly installed kitchen exhaust fans that terminated too close to windows and property lines, finally addressed through permits in 2022 and 2024. Historical issues include stairway safety concerns, with repairs required in 2000 and 2008, and a water heater seismic bracing violation noted in 2008. A 1992 reroofing project was permitted, though its status is now expired.

The most recent maintenance issues involve plumbing problems, as documented in December 2024 complaints, and there is an open pavement defect issue from April 2024. Regular routine inspections have occurred, with the most recent being in 2016. The building's maintenance history suggests ongoing challenges with infrastructure and systems, particularly regarding plumbing, ventilation, and surface maintenance.
