Augrented Insights Report

The two-story multi-family residential building at 1526-1528 California Street in Nob Hill, owned by the Chien Family Trust, was constructed in 1907 and contains two residential units and one commercial unit. The property has experienced significant recent maintenance issues, particularly with the roof and drainage systems. In early 2024, multiple complaints were filed regarding water leaks and drainage problems, including clogged and leaking roof drains, corroded drain stacks, and an unapproved sink drain, which were documented as health and safety violations.

The building underwent several repairs in 2024, including roof repairs, plumbing work, and drainage pipe replacements, with costs totaling approximately $9,500. The commercial space has seen some transitional use changes, notably converting from a computer store to a dry cleaning operation in 2014, including associated renovations such as flooring replacement and the installation of washers and dryers. Historical records show the building has faced various issues over the years, including electrical problems in 2000 with potentially hazardous wiring, compressor noise complaints in 2018, and a fire escape violation in 2006 that required correction.

The property has also been the subject of multiple 311 calls regarding sidewalk cleanliness and waste disposal, with recent reports in 2024 noting issues with garbage and debris on public property. In 2023-2024, the commercial tenant filed several complaints about water leaks and potential mold concerns, particularly regarding inadequate roof repairs and drainage systems, which became particularly problematic during rainy weather. While most recent violations were abated by February 2024, the recurring nature of water-related issues suggests ongoing infrastructure challenges. The building has received various permits for maintenance and improvements over the years, including electrical modifications and plumbing installations, indicating regular maintenance efforts by ownership.
