156 Duboce Ave, San Francisco, CA 94103

The 8-unit, 2-story apartment building at 156 Duboce Avenue, built in 1924, has undergone significant seismic improvements as part of San Francisco's mandatory soft-story retrofit program. The building, owned by Chang Sing & Chin Bee Cho T, successfully completed its soft-story retrofit in 2022, including a comprehensive fire system upgrade with new panel, smoke detectors, and low-frequency horns installed throughout all units.

The property has experienced several maintenance and compliance challenges over the years, with notable issues including a serious staircase safety concern in 2021-2022 when a section of stairs was replaced without proper permits, leading to code violations that were eventually resolved through proper repairs and permits in early 2022. Historical records show a pattern of building maintenance improvements and occasional compliance issues, including a significant window replacement project in 2010, garage foundation and mezzanine work in 2002, and various repairs and upgrades over the years.

The building has faced several tenant-related complaints regarding unauthorized work, including a 2019 complaint about unpermitted kitchen and bathroom renovations in Unit #1, and concerns about lead paint management during 2013 exterior painting work. More recent issues have included complaints about excessive noise during construction work in 2022 and concerns about sewage problems in 2014, though these were eventually resolved. The property has maintained active compliance with recent building safety requirements, evidenced by the issuance of the Certificate of Final Completion for the soft-story retrofit work.
